KernelVersion: 2.6.26
Contact: Dan Williams <dan.j.williams@intel.com>
Description: The /sys/dev tree provides a method to look up the sysfs
path for a device using the information returned from
stat(2). There are two directories, 'block' and 'char',
beneath /sys/dev containing symbolic links with names of
the form "<major>:<minor>". These links point to the
corresponding sysfs path for the given device.
Example:
$ readlink /sys/dev/block/8:32
../../block/sdc
Entries in /sys/dev/char and /sys/dev/block will be
dynamically created and destroyed as devices enter and
leave the system.

DMA_ATTR_WEAK_ORDERING specifies that reads and writes to the mapping
may be weakly ordered, that is that reads and writes may pass each other.
Since it is optional for platforms to implement DMA_ATTR_WEAK_ORDERING,

<para>
For some hardware that has more than one interrupt source internally,
but not separate IRQ mask and status registers, there might be
situations where userspace cannot determine what the interrupt source
was if the kernel handler disables them by writing to the chip's IRQ
register. In such a case, the kernel has to disable the IRQ completely
to leave the chip's register untouched. Now the userspace part can
determine the cause of the interrupt, but it cannot re-enable
interrupts. Another cornercase is chips where re-enabling interrupts
is a read-modify-write operation to a combined IRQ status/acknowledge
register. This would be racy if a new interrupt occurred
simultaneously.

Paravirt_ops on IA64
====================
21 May 2008, Isaku Yamahata <yamahata@valinux.co.jp>
Introduction
------------
The aim of this documentation is to help with maintainability and/or to
encourage people to use paravirt_ops/IA64.
paravirt_ops (pv_ops in short) is a way for virtualization support of
Linux kernel on x86. Several ways for virtualization support were
proposed, paravirt_ops is the winner.
On the other hand, now there are also several IA64 virtualization
technologies like kvm/IA64, xen/IA64 and many other academic IA64
hypervisors so that it is good to add generic virtualization
infrastructure on Linux/IA64.
What is paravirt_ops?
---------------------
It has been developed on x86 as virtualization support via API, not ABI.
It allows each hypervisor to override operations which are important for
hypervisors at API level. And it allows a single kernel binary to run on
all supported execution environments including native machine.
Essentially paravirt_ops is a set of function pointers which represent
operations corresponding to low level sensitive instructions and high
level functionalities in various area. But one significant difference
from usual function pointer table is that it allows optimization with
binary patch. It is because some of these operations are very
performance sensitive and indirect call overhead is not negligible.
With binary patch, indirect C function call can be transformed into
direct C function call or in-place execution to eliminate the overhead.
Thus, operations of paravirt_ops are classified into three categories.
- simple indirect call
These operations correspond to high level functionality so that the
overhead of indirect call isn't very important.
- indirect call which allows optimization with binary patch
Usually these operations correspond to low level instructions. They
are called frequently and performance critical. So the overhead is
very important.
- a set of macros for hand written assembly code
Hand written assembly codes (.S files) also need paravirtualization
because they include sensitive instructions or some of code paths in
them are very performance critical.
The relation to the IA64 machine vector
---------------------------------------
Linux/IA64 has the IA64 machine vector functionality which allows the
kernel to switch implementations (e.g. initialization, ipi, dma api...)
depending on executing platform.
We can replace some implementations very easily defining a new machine
vector. Thus another approach for virtualization support would be
enhancing the machine vector functionality.
But paravirt_ops approach was taken because
- virtualization support needs wider support than machine vector does.
e.g. low level instruction paravirtualization. It must be
initialized very early before platform detection.
- virtualization support needs more functionality like binary patch.
Probably the calling overhead might not be very large compared to the
emulation overhead of virtualization. However in the native case, the
overhead should be eliminated completely.
A single kernel binary should run on each environment including native,
and the overhead of paravirt_ops on native environment should be as
small as possible.
- for full virtualization technology, e.g. KVM/IA64 or
Xen/IA64 HVM domain, the result would be
(the emulated platform machine vector. probably dig) + (pv_ops).
This means that the virtualization support layer should be under
the machine vector layer.
Possibly it might be better to move some function pointers from
paravirt_ops to machine vector. In fact, Xen domU case utilizes both
pv_ops and machine vector.
IA64 paravirt_ops
-----------------
In this section, the concrete paravirt_ops will be discussed.
Because of the architecture difference between ia64 and x86, the
resulting set of functions is very different from x86 pv_ops.
- C function pointer tables
They are not very performance critical so that simple C indirect
function call is acceptable. The following structures are defined at
this moment. For details see linux/include/asm-ia64/paravirt.h
- struct pv_info
This structure describes the execution environment.
- struct pv_init_ops
This structure describes the various initialization hooks.
- struct pv_iosapic_ops
This structure describes hooks to iosapic operations.
- struct pv_irq_ops
This structure describes hooks to irq related operations
- struct pv_time_op
This structure describes hooks to steal time accounting.
- a set of indirect calls which need optimization
Currently this class of functions correspond to a subset of IA64
intrinsics. At this moment the optimization with binary patch isn't
implemented yet.
struct pv_cpu_op is defined. For details see
linux/include/asm-ia64/paravirt_privop.h
Mostly they correspond to ia64 intrinsics 1-to-1.
Caveat: Now they are defined as C indirect function pointers, but in
order to support binary patch optimization, they will be changed
using GCC extended inline assembly code.
- a set of macros for hand written assembly code (.S files)
For maintenance purpose, the taken approach for .S files is single
source code and compile multiple times with different macros definitions.
Each pv_ops instance must define those macros to compile.
The important thing here is that sensitive, but non-privileged
instructions must be paravirtualized and that some privileged
instructions also need paravirtualization for reasonable performance.
Developers who modify .S files must be aware of that. At this moment
an easy checker is implemented to detect paravirtualization breakage.
But it doesn't cover all the cases.
Sometimes this set of macros is called pv_cpu_asm_op. But there is no
corresponding structure in the source code.
Those macros mostly 1:1 correspond to a subset of privileged
instructions. See linux/include/asm-ia64/native/inst.h.
And some functions written in assembly also need to be overrided so
that each pv_ops instance have to define some macros. Again see
linux/include/asm-ia64/native/inst.h.
Those structures must be initialized very early before start_kernel.
Probably initialized in head.S using multi entry point or some other trick.
For native case implementation see linux/arch/ia64/kernel/paravirt.c.

Fail over MAC is useful for devices that cannot ever alter

the ARP monitor).
Possible values are:
The down side of fail over MAC is that every device on the
network must be updated via gratuitous ARP, vs. just updating
a switch or set of switches (which often takes place for any
traffic, not just ARP traffic, if the switch snoops incoming

the gratuitous ARP is lost, communication may be disrupted.
none or 0
When fail over MAC is used in conjuction with the mii monitor,
devices which assert link up prior to being able to actually
transmit and receive are particularly susecptible to loss of
the gratuitous ARP, and an appropriate updelay setting may be
required.
This setting disables fail_over_mac, and causes
bonding to set all slaves of an active-backup bond to
the same MAC address at enslavement time. This is the
default.
A value of 0 disables fail over MAC, and is the default. A
value of 1 enables fail over MAC. This option is enabled
automatically if the first slave added cannot change its MAC
address. This option may be modified via sysfs only when no
slaves are present in the bond.
active or 1
This option was added in bonding version 3.2.0.
The "active" fail_over_mac policy indicates that the
MAC address of the bond should always be the MAC
address of the currently active slave. The MAC
address of the slaves is not changed; instead, the MAC
address of the bond changes during a failover.
This policy is useful for devices that cannot ever
alter their MAC address, or for devices that refuse
incoming broadcasts with their own source MAC (which
interferes with the ARP monitor).
The down side of this policy is that every device on
the network must be updated via gratuitous ARP,

often takes place for any traffic, not just ARP
traffic, if the switch snoops incoming traffic to
update its tables) for the traditional method. If the

monitor, devices which assert link up prior to being
able to actually transmit and receive are particularly
susecptible to loss of the gratuitous ARP, and an
appropriate updelay setting may be required.
follow or 2
The "follow" fail_over_mac policy causes the MAC
address of the bond to be selected normally (normally
the MAC address of the first slave added to the bond).
However, the second and subsequent slaves are not set
to this MAC address while they are in a backup role; a
slave is programmed with the bond's MAC address at
failover time (and the formerly active slave receives
the newly active slave's MAC address).
This policy is useful for multiport devices that
either become confused or incur a performance penalty
when multiple ports are programmed with the same MAC
address.
The default policy is none, unless the first slave cannot
change its MAC address, in which case the active policy is
selected by default.
This option may be modified via sysfs only when no slaves are
present in the bond.

DM9000 Network driver
=====================
Copyright 2008 Simtec Electronics,
Ben Dooks <ben@simtec.co.uk> <ben-linux@fluff.org>
Introduction
------------
This file describes how to use the DM9000 platform-device based network driver
that is contained in the files drivers/net/dm9000.c and drivers/net/dm9000.h.
The driver supports three DM9000 variants, the DM9000E which is the first chip
supported as well as the newer DM9000A and DM9000B devices. It is currently
maintained and tested by Ben Dooks, who should be CC: to any patches for this
driver.
Defining the platform device
----------------------------
The minimum set of resources attached to the platform device are as follows:
1) The physical address of the address register
2) The physical address of the data register
3) The IRQ line the device's interrupt pin is connected to.
These resources should be specified in that order, as the ordering of the
two address regions is important (the driver expects these to be address
and then data).
An example from arch/arm/mach-s3c2410/mach-bast.c is:
static struct resource bast_dm9k_resource[] = {
[0] = {
.start = S3C2410_CS5 + BAST_PA_DM9000,
.end = S3C2410_CS5 + BAST_PA_DM9000 + 3,
.flags = IORESOURCE_MEM,
},
[1] = {
.start = S3C2410_CS5 + BAST_PA_DM9000 + 0x40,
.end = S3C2410_CS5 + BAST_PA_DM9000 + 0x40 + 0x3f,
.flags = IORESOURCE_MEM,
},
[2] = {
.start = IRQ_DM9000,
.end = IRQ_DM9000,
.flags = IORESOURCE_IRQ | IORESOURCE_IRQ_HIGHLEVEL,
}
};
static struct platform_device bast_device_dm9k = {
.name = "dm9000",
.id = 0,
.num_resources = ARRAY_SIZE(bast_dm9k_resource),
.resource = bast_dm9k_resource,
};
Note the setting of the IRQ trigger flag in bast_dm9k_resource[2].flags,
as this will generate a warning if it is not present. The trigger from
the flags field will be passed to request_irq() when registering the IRQ
handler to ensure that the IRQ is setup correctly.
This shows a typical platform device, without the optional configuration
platform data supplied. The next example uses the same resources, but adds
the optional platform data to pass extra configuration data:
static struct dm9000_plat_data bast_dm9k_platdata = {
.flags = DM9000_PLATF_16BITONLY,
};
static struct platform_device bast_device_dm9k = {
.name = "dm9000",
.id = 0,
.num_resources = ARRAY_SIZE(bast_dm9k_resource),
.resource = bast_dm9k_resource,
.dev = {
.platform_data = &bast_dm9k_platdata,
}
};
The platform data is defined in include/linux/dm9000.h and described below.
Platform data
-------------
Extra platform data for the DM9000 can describe the IO bus width to the
device, whether or not an external PHY is attached to the device and
the availability of an external configuration EEPROM.
The flags for the platform data .flags field are as follows:
DM9000_PLATF_8BITONLY
The IO should be done with 8bit operations.
DM9000_PLATF_16BITONLY
The IO should be done with 16bit operations.
DM9000_PLATF_32BITONLY
The IO should be done with 32bit operations.
DM9000_PLATF_EXT_PHY
The chip is connected to an external PHY.
DM9000_PLATF_NO_EEPROM
This can be used to signify that the board does not have an
EEPROM, or that the EEPROM should be hidden from the user.
DM9000_PLATF_SIMPLE_PHY
Switch to using the simpler PHY polling method which does not
try and read the MII PHY state regularly. This is only available
when using the internal PHY. See the section on link state polling
for more information.
The config symbol DM9000_FORCE_SIMPLE_PHY_POLL, Kconfig entry
"Force simple NSR based PHY polling" allows this flag to be
forced on at build time.
PHY Link state polling
----------------------
The driver keeps track of the link state and informs the network core
about link (carrier) availablilty. This is managed by several methods
depending on the version of the chip and on which PHY is being used.
For the internal PHY, the original (and currently default) method is
to read the MII state, either when the status changes if we have the
necessary interrupt support in the chip or every two seconds via a
periodic timer.
To reduce the overhead for the internal PHY, there is now the option
of using the DM9000_FORCE_SIMPLE_PHY_POLL config, or DM9000_PLATF_SIMPLE_PHY
platform data option to read the summary information without the
expensive MII accesses. This method is faster, but does not print
as much information.
When using an external PHY, the driver currently has to poll the MII
link status as there is no method for getting an interrupt on link change.
DM9000A / DM9000B
-----------------
These chips are functionally similar to the DM9000E and are supported easily
by the same driver. The features are:
1) Interrupt on internal PHY state change. This means that the periodic
polling of the PHY status may be disabled on these devices when using
the internal PHY.
2) TCP/UDP checksum offloading, which the driver does not currently support.
ethtool
-------
The driver supports the ethtool interface for access to the driver
state information, the PHY state and the EEPROM.

This file describes the Linux* Base Driver for the Intel(R) PRO/10GbE Family
of Adapters, version 1.0.x.
This file describes the ixgb Linux Base Driver for the 10 Gigabit Intel(R)
Network Connection. This driver includes support for Itanium(R)2-based
systems.
For questions related to hardware requirements, refer to the documentation
supplied with your 10 Gigabit adapter. All hardware requirements listed apply
to use with Linux.
The following features are available in this kernel:
- Native VLANs
- Channel Bonding (teaming)
- SNMP
Channel Bonding documentation can be found in the Linux kernel source:
/Documentation/networking/bonding.txt
The driver information previously displayed in the /proc filesystem is not
supported in this release. Alternatively, you can use ethtool (version 1.6
or later), lspci, and ifconfig to obtain the same information.
Instructions on updating ethtool can be found in the section "Additional
Configurations" later in this document.
For questions related to hardware requirements, refer to the documentation
supplied with your Intel PRO/10GbE adapter. All hardware requirements listed
apply to use with Linux.
Identifying Your Adapter
========================
To verify your Intel adapter is supported, find the board ID number on the
adapter. Look for a label that has a barcode and a number in the format
A12345-001.

NOTE: These changes are only suggestions, and serve as a starting point for

The changes are made in three major ways, listed in order of greatest effect:
- Use ifconfig to modify the mtu (maximum transmission unit) and the txqueuelen
- Use ifconfig to modify the mtu (maximum transmission unit) and the txqueuelen
parameter.
- Use sysctl to modify /proc parameters (essentially kernel tuning)
- Use setpci to modify the MMRBC field in PCI-X configuration space to increase
- Use setpci to modify the MMRBC field in PCI-X configuration space to increase
transmit burst lengths on the bus.
NOTE: setpci modifies the adapter's configuration registers to allow it to read
up to 4k bytes at a time (for transmits). However, for some systems the
behavior after modifying this register may be undefined (possibly errors of some
kind). A power-cycle, hard reset or explicitly setting the e6 register back to

configuration.
NOTE: setpci modifies the adapter's configuration registers to allow it to read
up to 4k bytes at a time (for transmits). However, for some systems the
behavior after modifying this register may be undefined (possibly errors of
some kind). A power-cycle, hard reset or explicitly setting the e6 register
back to 22 (setpci -d 8086:1a48 e6.b=22) may be required to get back to a
stable configuration.

Resolving Slow UDP Traffic
--------------------------
If your server does not seem to be able to receive UDP traffic as fast as it
can receive TCP traffic, it could be because Linux, by default, does not set
the network stack buffers as large as they need to be to support high UDP
transfer rates. One way to alleviate this problem is to allow more memory to
be used by the IP stack to store incoming data.

For instance, use the commands:
sysctl -w net.core.rmem_max=262143
and
sysctl -w net.core.rmem_default=262143
to increase the read buffer memory max and default to 262143 (256k - 1) from
defaults of max=131071 (128k - 1) and default=65535 (64k - 1). These variables
will increase the amount of memory used by the network stack for receives, and
to increase the read buffer memory max and default to 262143 (256k - 1) from
defaults of max=131071 (128k - 1) and default=65535 (64k - 1). These variables
will increase the amount of memory used by the network stack for receives, and
can be increased significantly more if necessary for your application.
Additional Configurations
=========================
Configuring the Driver on Different Distributions
-------------------------------------------------
Configuring a network driver to load properly when the system is started is
distribution dependent. Typically, the configuration process involves adding
an alias line to /etc/modprobe.conf as well as editing other system startup
scripts and/or configuration files. Many popular Linux distributions ship
with tools to make these changes for you. To learn the proper way to
configure a network device for your system, refer to your distribution
documentation. If during this process you are asked for the driver or module
name, the name for the Linux Base Driver for the Intel 10GbE Family of
Adapters is ixgb.
Viewing Link Messages
---------------------
Link messages will not be displayed to the console if the distribution is
restricting system messages. In order to see network driver link messages on
your console, set dmesg to eight by entering the following:
dmesg -n 8
NOTE: This setting is not saved across reboots.
Jumbo Frames
------------
The driver supports Jumbo Frames for all adapters. Jumbo Frames support is
enabled by changing the MTU to a value larger than the default of 1500.
The maximum value for the MTU is 16114. Use the ifconfig command to
increase the MTU size. For example:
ifconfig ethx mtu 9000 up
The maximum MTU setting for Jumbo Frames is 16114. This value coincides
with the maximum Jumbo Frames size of 16128.
Ethtool
-------
The driver utilizes the ethtool interface for driver configuration and
diagnostics, as well as displaying statistical information. Ethtool
version 1.6 or later is required for this functionality.
The latest release of ethtool can be found from
http://sourceforge.net/projects/gkernel
NOTE: Ethtool 1.6 only supports a limited set of ethtool options. Support
for a more complete ethtool feature set can be enabled by upgrading
to the latest version.
NAPI
----
NAPI (Rx polling mode) is supported in the ixgb driver. NAPI is enabled
or disabled based on the configuration of the kernel. see CONFIG_IXGB_NAPI
See www.cyberus.ca/~hadi/usenix-paper.tgz for more information on NAPI.
Known Issues/Troubleshooting
============================
NOTE: After installing the driver, if your Intel Network Connection is not
working, verify in the "In This Release" section of the readme that you have
installed the correct driver.
Intel(R) PRO/10GbE CX4 Server Adapter Cable Interoperability Issue with
Fujitsu XENPAK Module in SmartBits Chassis
---------------------------------------------------------------------
Excessive CRC errors may be observed if the Intel(R) PRO/10GbE CX4
Server adapter is connected to a Fujitsu XENPAK CX4 module in a SmartBits
chassis using 15 m/24AWG cable assemblies manufactured by Fujitsu or Leoni.
The CRC errors may be received either by the Intel(R) PRO/10GbE CX4
Server adapter or the SmartBits. If this situation occurs using a different
cable assembly may resolve the issue.
CX4 Server Adapter Cable Interoperability Issues with HP Procurve 3400cl
Switch Port
------------------------------------------------------------------------
Excessive CRC errors may be observed if the Intel(R) PRO/10GbE CX4 Server
adapter is connected to an HP Procurve 3400cl switch port using short cables
(1 m or shorter). If this situation occurs, using a longer cable may resolve
the issue.
Excessive CRC errors may be observed using Fujitsu 24AWG cable assemblies that
Are 10 m or longer or where using a Leoni 15 m/24AWG cable assembly. The CRC
errors may be received either by the CX4 Server adapter or at the switch. If
this situation occurs, using a different cable assembly may resolve the issue.
Jumbo Frames System Requirement
-------------------------------
Memory allocation failures have been observed on Linux systems with 64 MB
of RAM or less that are running Jumbo Frames. If you are using Jumbo
Frames, your system may require more than the advertised minimum
requirement of 64 MB of system memory.
Performance Degradation with Jumbo Frames
-----------------------------------------
Degradation in throughput performance may be observed in some Jumbo frames
environments. If this is observed, increasing the application's socket buffer
size and/or increasing the /proc/sys/net/ipv4/tcp_*mem entry values may help.
See the specific application manual and /usr/src/linux*/Documentation/
networking/ip-sysctl.txt for more details.
Allocating Rx Buffers when Using Jumbo Frames
---------------------------------------------
Allocating Rx buffers when using Jumbo Frames on 2.6.x kernels may fail if
the available memory is heavily fragmented. This issue may be seen with PCI-X
adapters or with packet split disabled. This can be reduced or eliminated
by changing the amount of available memory for receive buffer allocation, by
increasing /proc/sys/vm/min_free_kbytes.
Multiple Interfaces on Same Ethernet Broadcast Network
------------------------------------------------------
Due to the default ARP behavior on Linux, it is not possible to have
one system on two IP networks in the same Ethernet broadcast domain
(non-partitioned switch) behave as expected. All Ethernet interfaces
will respond to IP traffic for any IP address assigned to the system.
This results in unbalanced receive traffic.
If you have multiple interfaces in a server, do either of the following:
- Turn on ARP filtering by entering:
echo 1 > /proc/sys/net/ipv4/conf/all/arp_filter
- Install the interfaces in separate broadcast domains - either in
different switches or in a switch partitioned to VLANs.
UDP Stress Test Dropped Packet Issue
--------------------------------------
Under small packets UDP stress test with 10GbE driver, the Linux system
may drop UDP packets due to the fullness of socket buffers. You may want
to change the driver's Flow Control variables to the minimum value for
controlling packet reception.
Tx Hangs Possible Under Stress
------------------------------
Under stress conditions, if TX hangs occur, turning off TSO
"ethtool -K eth0 tso off" may resolve the problem.

mac80211_hwsim - software simulator of 802.11 radio(s) for mac80211

Introduction
mac80211_hwsim is a Linux kernel module that can be used to simulate
arbitrary number of IEEE 802.11 radios for mac80211. It can be used to
test most of the mac80211 functionality and user space tools (e.g.,
hostapd and wpa_supplicant) in a way that matches very closely with
the normal case of using real WLAN hardware. From the mac80211 view
point, mac80211_hwsim is yet another hardware driver, i.e., no changes
to mac80211 are needed to use this testing tool.
The main goal for mac80211_hwsim is to make it easier for developers
to test their code and work with new features to mac80211, hostapd,
and wpa_supplicant. The simulated radios do not have the limitations
of real hardware, so it is easy to generate an arbitrary test setup
and always reproduce the same setup for future tests. In addition,
since all radio operation is simulated, any channel can be used in
tests regardless of regulatory rules.
mac80211_hwsim kernel module has a parameter 'radios' that can be used
to select how many radios are simulated (default 2). This allows
configuration of both very simply setups (e.g., just a single access
point and a station) or large scale tests (multiple access points with
hundreds of stations).
mac80211_hwsim works by tracking the current channel of each virtual
radio and copying all transmitted frames to all other radios that are
currently enabled and on the same channel as the transmitting
radio. Software encryption in mac80211 is used so that the frames are
actually encrypted over the virtual air interface to allow more
complete testing of encryption.
A global monitoring netdev, hwsim#, is created independent of
mac80211. This interface can be used to monitor all transmitted frames
regardless of channel.
Simple example
This example shows how to use mac80211_hwsim to simulate two radios:
one to act as an access point and the other as a station that
associates with the AP. hostapd and wpa_supplicant are used to take
care of WPA2-PSK authentication. In addition, hostapd is also
processing access point side of association.
Please note that the current Linux kernel does not enable AP mode, so a
simple patch is needed to enable AP mode selection:
http://johannes.sipsolutions.net/patches/kernel/all/LATEST/006-allow-ap-vlan-modes.patch
# Build mac80211_hwsim as part of kernel configuration
# Load the module
modprobe mac80211_hwsim
# Run hostapd (AP) for wlan0
hostapd hostapd.conf
# Run wpa_supplicant (station) for wlan1

Intro: Kernel support for multiqueue devices
---------------------------------------------------------
Kernel support for multiqueue devices is only an API that is presented to the
netdevice layer for base drivers to implement. This feature is part of the
core networking stack, and all network devices will be running on the
multiqueue-aware stack. If a base driver only has one queue, then these
changes are transparent to that driver.
Kernel support for multiqueue devices is always present.
Section 1: Base driver requirements for implementing multiqueue support
-----------------------------------------------------------------------
@ -32,84 +24,4 @@ netif_{start|stop|wake}_subqueue() functions to manage each queue while the
device is still operational. netdev->queue_lock is still used when the device
comes online or when it's completely shut down (unregister_netdev(), etc.).
Finally, the base driver should indicate that it is a multiqueue device. The
feature flag NETIF_F_MULTI_QUEUE should be added to the netdev->features
bitmap on device initialization. Below is an example from e1000:
#ifdef CONFIG_E1000_MQ
if ( (adapter->hw.mac.type == e1000_82571) ||
(adapter->hw.mac.type == e1000_82572) ||
(adapter->hw.mac.type == e1000_80003es2lan))
netdev->features |= NETIF_F_MULTI_QUEUE;
#endif
Section 2: Qdisc support for multiqueue devices
-----------------------------------------------
Currently two qdiscs support multiqueue devices. A new round-robin qdisc,
sch_rr, and sch_prio. The qdisc is responsible for classifying the skb's to
bands and queues, and will store the queue mapping into skb->queue_mapping.
Use this field in the base driver to determine which queue to send the skb
to.
sch_rr has been added for hardware that doesn't want scheduling policies from
software, so it's a straight round-robin qdisc. It uses the same syntax and
classification priomap that sch_prio uses, so it should be intuitive to
configure for people who've used sch_prio.
In order to utilitize the multiqueue features of the qdiscs, the network
device layer needs to enable multiple queue support. This can be done by
selecting NETDEVICES_MULTIQUEUE under Drivers.
The PRIO qdisc naturally plugs into a multiqueue device. If
NETDEVICES_MULTIQUEUE is selected, then on qdisc load, the number of
bands requested is compared to the number of queues on the hardware. If they
are equal, it sets a one-to-one mapping up between the queues and bands. If
they're not equal, it will not load the qdisc. This is the same behavior
for RR. Once the association is made, any skb that is classified will have
skb->queue_mapping set, which will allow the driver to properly queue skb's
to multiple queues.
Section 3: Brief howto using PRIO and RR for multiqueue devices
---------------------------------------------------------------
The userspace command 'tc,' part of the iproute2 package, is used to configure
qdiscs. To add the PRIO qdisc to your network device, assuming the device is
called eth0, run the following command:
# tc qdisc add dev eth0 root handle 1: prio bands 4 multiqueue
This will create 4 bands, 0 being highest priority, and associate those bands
to the queues on your NIC. Assuming eth0 has 4 Tx queues, the band mapping
would look like:
band 0 => queue 0
band 1 => queue 1
band 2 => queue 2
band 3 => queue 3
Traffic will begin flowing through each queue if your TOS values are assigning
traffic across the various bands. For example, ssh traffic will always try to
go out band 0 based on TOS -> Linux priority conversion (realtime traffic),
so it will be sent out queue 0. ICMP traffic (pings) fall into the "normal"
traffic classification, which is band 1. Therefore pings will be send out
queue 1 on the NIC.
Note the use of the multiqueue keyword. This is only in versions of iproute2
that support multiqueue networking devices; if this is omitted when loading
a qdisc onto a multiqueue device, the qdisc will load and operate the same
if it were loaded onto a single-queue device (i.e. - sends all traffic to
queue 0).
Another alternative to multiqueue band allocation can be done by using the
multiqueue option and specify 0 bands. If this is the case, the qdisc will
allocate the number of bands to equal the number of queues that the device
reports, and bring the qdisc online.
The behavior of tc filters remains the same, where it will override TOS priority
classification.

X - Specifying Device Power Management Information (sleep property)
===================================================================
Devices on SOCs often have mechanisms for placing devices into low-power
states that are decoupled from the devices' own register blocks. Sometimes,
this information is more complicated than a cell-index property can
reasonably describe. Thus, each device controlled in such a manner
may contain a "sleep" property which describes these connections.
The sleep property consists of one or more sleep resources, each of
which consists of a phandle to a sleep controller, followed by a
controller-specific sleep specifier of zero or more cells.
The semantics of what type of low power modes are possible are defined
by the sleep controller. Some examples of the types of low power modes
that may be supported are:
- Dynamic: The device may be disabled or enabled at any time.
- System Suspend: The device may request to be disabled or remain
awake during system suspend, but will not be disabled until then.
- Permanent: The device is disabled permanently (until the next hard
reset).
Some devices may share a clock domain with each other, such that they should
only be suspended when none of the devices are in use. Where reasonable,
such nodes should be placed on a virtual bus, where the bus has the sleep
property. If the clock domain is shared among devices that cannot be
reasonably grouped in this manner, then create a virtual sleep controller
(similar to an interrupt nexus, except that defining a standardized
sleep-map should wait until its necessity is demonstrated).

rfkill - RF switch subsystem support

1. Introduction:
The rfkill switch subsystem exists to add a generic interface to circuitry that
can enable or disable the signal output of a wireless *transmitter* of any
type. By far, the most common use is to disable radio-frequency transmitters.
Note that disabling the signal output means that the the transmitter is to be
made to not emit any energy when "blocked". rfkill is not about blocking data
transmissions, it is about blocking energy emission.
The rfkill subsystem offers support for keys and switches often found on
laptops to enable wireless devices like WiFi and Bluetooth, so that these keys
and switches actually perform an action in all wireless devices of a given type
attached to the system.
The buttons to enable and disable the wireless transmitters are important in
situations where the user is for example using his laptop on a location where
radio-frequency transmitters _must_ be disabled (e.g. airplanes).
Because of this requirement, userspace support for the keys should not be made
mandatory. Because userspace might want to perform some additional smarter
tasks when the key is pressed, rfkill provides userspace the possibility to
take over the task to handle the key events.
===============================================================================
1: Implementation details
2: Implementation details
The rfkill switch subsystem offers support for keys often found on laptops
to enable wireless devices like WiFi and Bluetooth.
The rfkill subsystem is composed of various components: the rfkill class, the
rfkill-input module (an input layer handler), and some specific input layer
events.
This is done by providing the user 3 possibilities:
1 - The rfkill system handles all events; userspace is not aware of events.
2 - The rfkill system handles all events; userspace is informed about the events.
3 - The rfkill system does not handle events; userspace handles all events.
The rfkill class provides kernel drivers with an interface that allows them to
know when they should enable or disable a wireless network device transmitter.
This is enabled by the CONFIG_RFKILL Kconfig option.
The buttons to enable and disable the wireless radios are important in
situations where the user is for example using his laptop on a location where
wireless radios _must_ be disabled (e.g. airplanes).
Because of this requirement, userspace support for the keys should not be
made mandatory. Because userspace might want to perform some additional smarter
tasks when the key is pressed, rfkill still provides userspace the possibility
to take over the task to handle the key events.
The rfkill class support makes sure userspace will be notified of all state
changes on rfkill devices through uevents. It provides a notification chain
for interested parties in the kernel to also get notified of rfkill state
changes in other drivers. It creates several sysfs entries which can be used
by userspace. See section "Userspace support".
The system inside the kernel has been split into 2 separate sections:
1 - RFKILL
2 - RFKILL_INPUT
The rfkill-input module provides the kernel with the ability to implement a
basic response when the user presses a key or button (or toggles a switch)
related to rfkill functionality. It is an in-kernel implementation of default
policy of reacting to rfkill-related input events and neither mandatory nor
required for wireless drivers to operate. It is enabled by the
CONFIG_RFKILL_INPUT Kconfig option.
The first option enables rfkill support and will make sure userspace will
be notified of any events through the input device. It also creates several
sysfs entries which can be used by userspace. See section "Userspace support".
rfkill-input is a rfkill-related events input layer handler. This handler will
listen to all rfkill key events and will change the rfkill state of the
wireless devices accordingly. With this option enabled userspace could either
do nothing or simply perform monitoring tasks.
The second option provides an rfkill input handler. This handler will
listen to all rfkill key events and will toggle the radio accordingly.
With this option enabled userspace could either do nothing or simply
perform monitoring tasks.
The rfkill-input module also provides EPO (emergency power-off) functionality
for all wireless transmitters. This function cannot be overridden, and it is
always active. rfkill EPO is related to *_RFKILL_ALL input layer events.
Important terms for the rfkill subsystem:
In order to avoid confusion, we avoid the term "switch" in rfkill when it is
referring to an electronic control circuit that enables or disables a
transmitter. We reserve it for the physical device a human manipulates
(which is an input device, by the way):
rfkill switch:
A physical device a human manipulates. Its state can be perceived by
the kernel either directly (through a GPIO pin, ACPI GPE) or by its
effect on a rfkill line of a wireless device.
rfkill controller:
A hardware circuit that controls the state of a rfkill line, which a
kernel driver can interact with *to modify* that state (i.e. it has
either write-only or read/write access).
rfkill line:
An input channel (hardware or software) of a wireless device, which
causes a wireless transmitter to stop emitting energy (BLOCK) when it
is active. Point of view is extremely important here: rfkill lines are
always seen from the PoV of a wireless device (and its driver).
soft rfkill line/software rfkill line:
A rfkill line the wireless device driver can directly change the state
of. Related to rfkill_state RFKILL_STATE_SOFT_BLOCKED.
hard rfkill line/hardware rfkill line:
A rfkill line that works fully in hardware or firmware, and that cannot
be overridden by the kernel driver. The hardware device or the
firmware just exports its status to the driver, but it is read-only.
Related to rfkill_state RFKILL_STATE_HARD_BLOCKED.
The enum rfkill_state describes the rfkill state of a transmitter:
When a rfkill line or rfkill controller is in the RFKILL_STATE_UNBLOCKED state,
the wireless transmitter (radio TX circuit for example) is *enabled*. When the
it is in the RFKILL_STATE_SOFT_BLOCKED or RFKILL_STATE_HARD_BLOCKED, the
wireless transmitter is to be *blocked* from operating.
RFKILL_STATE_SOFT_BLOCKED indicates that a call to toggle_radio() can change
that state. RFKILL_STATE_HARD_BLOCKED indicates that a call to toggle_radio()
will not be able to change the state and will return with a suitable error if
attempts are made to set the state to RFKILL_STATE_UNBLOCKED.
RFKILL_STATE_HARD_BLOCKED is used by drivers to signal that the device is
locked in the BLOCKED state by a hardwire rfkill line (typically an input pin
that, when active, forces the transmitter to be disabled) which the driver
CANNOT override.
Full rfkill functionality requires two different subsystems to cooperate: the
input layer and the rfkill class. The input layer issues *commands* to the
entire system requesting that devices registered to the rfkill class change
state. The way this interaction happens is not complex, but it is not obvious
either:
Kernel Input layer:
* Generates KEY_WWAN, KEY_WLAN, KEY_BLUETOOTH, SW_RFKILL_ALL, and
other such events when the user presses certain keys, buttons, or
toggles certain physical switches.
THE INPUT LAYER IS NEVER USED TO PROPAGATE STATUS, NOTIFICATIONS OR THE
KIND OF STUFF AN ON-SCREEN-DISPLAY APPLICATION WOULD REPORT. It is
used to issue *commands* for the system to change behaviour, and these
commands may or may not be carried out by some kernel driver or
userspace application. It follows that doing user feedback based only
on input events is broken, as there is no guarantee that an input event
will be acted upon.
Most wireless communication device drivers implementing rfkill
functionality MUST NOT generate these events, and have no reason to
register themselves with the input layer. Doing otherwise is a common
misconception. There is an API to propagate rfkill status change
information, and it is NOT the input layer.
rfkill class:
* Calls a hook in a driver to effectively change the wireless
transmitter state;
* Keeps track of the wireless transmitter state (with help from
the driver);
* Generates userspace notifications (uevents) and a call to a
notification chain (kernel) when there is a wireless transmitter
state change;
* Connects a wireless communications driver with the common rfkill
control system, which, for example, allows actions such as
"switch all bluetooth devices offline" to be carried out by
userspace or by rfkill-input.
THE RFKILL CLASS NEVER ISSUES INPUT EVENTS. THE RFKILL CLASS DOES
NOT LISTEN TO INPUT EVENTS. NO DRIVER USING THE RFKILL CLASS SHALL
EVER LISTEN TO, OR ACT ON RFKILL INPUT EVENTS. Doing otherwise is
a layering violation.
Most wireless data communication drivers in the kernel have just to
implement the rfkill class API to work properly. Interfacing to the
input layer is not often required (and is very often a *bug*) on
wireless drivers.
Platform drivers often have to attach to the input layer to *issue*
(but never to listen to) rfkill events for rfkill switches, and also to
the rfkill class to export a control interface for the platform rfkill
controllers to the rfkill subsystem. This does NOT mean the rfkill
switch is attached to a rfkill class (doing so is almost always wrong).
It just means the same kernel module is the driver for different
devices (rfkill switches and rfkill controllers).
Userspace input handlers (uevents) or kernel input handlers (rfkill-input):
* Implements the policy of what should happen when one of the input
layer events related to rfkill operation is received.
* Uses the sysfs interface (userspace) or private rfkill API calls
to tell the devices registered with the rfkill class to change
their state (i.e. translates the input layer event into real
action).
* rfkill-input implements EPO by handling EV_SW SW_RFKILL_ALL 0
(power off all transmitters) in a special way: it ignores any
overrides and local state cache and forces all transmitters to the
RFKILL_STATE_SOFT_BLOCKED state (including those which are already
supposed to be BLOCKED). Note that the opposite event (power on all
transmitters) is handled normally.
Userspace uevent handler or kernel platform-specific drivers hooked to the
rfkill notifier chain:
* Taps into the rfkill notifier chain or to KOBJ_CHANGE uevents,
in order to know when a device that is registered with the rfkill
class changes state;
* Issues feedback notifications to the user;
* In the rare platforms where this is required, synthesizes an input
event to command all *OTHER* rfkill devices to also change their
statues when a specific rfkill device changes state.

3: Kernel driver guidelines
Remember: point-of-view is everything for a driver that connects to the rfkill
subsystem. All the details below must be measured/perceived from the point of
view of the specific driver being modified.
The first thing one needs to know is whether his driver should be talking to
the rfkill class or to the input layer. In rare cases (platform drivers), it
could happen that you need to do both, as platform drivers often handle a
variety of devices in the same driver.
Do not mistake input devices for rfkill controllers. The only type of "rfkill
switch" device that is to be registered with the rfkill class are those
directly controlling the circuits that cause a wireless transmitter to stop
working (or the software equivalent of them), i.e. what we call a rfkill
controller. Every other kind of "rfkill switch" is just an input device and
MUST NOT be registered with the rfkill class.
A driver should register a device with the rfkill class when ALL of the
following conditions are met (they define a rfkill controller):
1. The device is/controls a data communications wireless transmitter;
2. The kernel can interact with the hardware/firmware to CHANGE the wireless
transmitter state (block/unblock TX operation);
3. The transmitter can be made to not emit any energy when "blocked":
rfkill is not about blocking data transmissions, it is about blocking
energy emission;
A driver should register a device with the input subsystem to issue
rfkill-related events (KEY_WLAN, KEY_BLUETOOTH, KEY_WWAN, KEY_WIMAX,
SW_RFKILL_ALL, etc) when ALL of the folowing conditions are met:
1. It is directly related to some physical device the user interacts with, to
command the O.S./firmware/hardware to enable/disable a data communications
wireless transmitter.
Examples of the physical device are: buttons, keys and switches the user
will press/touch/slide/switch to enable or disable the wireless
communication device.
2. It is NOT slaved to another device, i.e. there is no other device that
issues rfkill-related input events in preference to this one.
Please refer to the corner cases and examples section for more details.
When in doubt, do not issue input events. For drivers that should generate
input events in some platforms, but not in others (e.g. b43), the best solution
is to NEVER generate input events in the first place. That work should be
deferred to a platform-specific kernel module (which will know when to generate
events through the rfkill notifier chain) or to userspace. This avoids the
usual maintenance problems with DMI whitelisting.
Corner cases and examples:
====================================
2: Driver support
To build a driver with rfkill subsystem support, the driver should
depend on the Kconfig symbol RFKILL; it should _not_ depend on
RKFILL_INPUT.
1. If the device is an input device that, because of hardware or firmware,
causes wireless transmitters to be blocked regardless of the kernel's will, it
is still just an input device, and NOT to be registered with the rfkill class.
Unless key events trigger an interrupt to which the driver listens, polling
will be required to determine the key state changes. For this the input
layer providers the input-polldev handler.
2. If the wireless transmitter switch control is read-only, it is an input
device and not to be registered with the rfkill class (and maybe not to be made
an input layer event source either, see below).
A driver should implement a few steps to correctly make use of the
rfkill subsystem. First for non-polling drivers:
3. If there is some other device driver *closer* to the actual hardware the
user interacted with (the button/switch/key) to issue an input event, THAT is
the device driver that should be issuing input events.
- rfkill_allocate()
- input_allocate_device()
- rfkill_register()
- input_register_device()
E.g:
[RFKILL slider switch] -- [GPIO hardware] -- [WLAN card rf-kill input]
(platform driver) (wireless card driver)
For polling drivers:
The user is closer to the RFKILL slide switch plaform driver, so the driver
which must issue input events is the platform driver looking at the GPIO
hardware, and NEVER the wireless card driver (which is just a slave). It is
very likely that there are other leaves than just the WLAN card rf-kill input
(e.g. a bluetooth card, etc)...
- rfkill_allocate()
- input_allocate_polled_device()
- rfkill_register()
- input_register_polled_device()
On the other hand, some embedded devices do this:
When a key event has been detected, the correct event should be
sent over the input device which has been registered by the driver.
[RFKILL slider switch] -- [WLAN card rf-kill input]
(wireless card driver)
In this situation, the wireless card driver *could* register itself as an input
device and issue rf-kill related input events... but in order to AVOID the need
for DMI whitelisting, the wireless card driver does NOT do it. Userspace (HAL)
or a platform driver (that exists only on these embedded devices) will do the
dirty job of issuing the input events.
COMMON MISTAKES in kernel drivers, related to rfkill:
====================================
3: Userspace support
For each key an input device will be created which will send out the correct
key event when the rfkill key has been pressed.
1. NEVER confuse input device keys and buttons with input device switches.
1a. Switches are always set or reset. They report the current state
(on position or off position).
1b. Keys and buttons are either in the pressed or not-pressed state, and
that's it. A "button" that latches down when you press it, and
unlatches when you press it again is in fact a switch as far as input
devices go.
Add the SW_* events you need for switches, do NOT try to emulate a button using
KEY_* events just because there is no such SW_* event yet. Do NOT try to use,
for example, KEY_BLUETOOTH when you should be using SW_BLUETOOTH instead.
2. Input device switches (sources of EV_SW events) DO store their current state
(so you *must* initialize it by issuing a gratuitous input layer event on
driver start-up and also when resuming from sleep), and that state CAN be
queried from userspace through IOCTLs. There is no sysfs interface for this,
but that doesn't mean you should break things trying to hook it to the rfkill
class to get a sysfs interface :-)
3. Do not issue *_RFKILL_ALL events by default, unless you are sure it is the
correct event for your switch/button. These events are emergency power-off
events when they are trying to turn the transmitters off. An example of an
input device which SHOULD generate *_RFKILL_ALL events is the wireless-kill
switch in a laptop which is NOT a hotkey, but a real switch that kills radios
in hardware, even if the O.S. has gone to lunch. An example of an input device
which SHOULD NOT generate *_RFKILL_ALL events by default, is any sort of hot
key that does nothing by itself, as well as any hot key that is type-specific
(e.g. the one for WLAN).
3.1 Guidelines for wireless device drivers
------------------------------------------
1. Each independent transmitter in a wireless device (usually there is only one
transmitter per device) should have a SINGLE rfkill class attached to it.
2. If the device does not have any sort of hardware assistance to allow the
driver to rfkill the device, the driver should emulate it by taking all actions
required to silence the transmitter.
3. If it is impossible to silence the transmitter (i.e. it still emits energy,
even if it is just in brief pulses, when there is no data to transmit and there
is no hardware support to turn it off) do NOT lie to the users. Do not attach
it to a rfkill class. The rfkill subsystem does not deal with data
transmission, it deals with energy emission. If the transmitter is emitting
energy, it is not blocked in rfkill terms.
4. It doesn't matter if the device has multiple rfkill input lines affecting
the same transmitter, their combined state is to be exported as a single state
per transmitter (see rule 1).
This rule exists because users of the rfkill subsystem expect to get (and set,
when possible) the overall transmitter rfkill state, not of a particular rfkill
line.
Example of a WLAN wireless driver connected to the rfkill subsystem:
--------------------------------------------------------------------
A certain WLAN card has one input pin that causes it to block the transmitter
and makes the status of that input pin available (only for reading!) to the
kernel driver. This is a hard rfkill input line (it cannot be overridden by
the kernel driver).
The card also has one PCI register that, if manipulated by the driver, causes
it to block the transmitter. This is a soft rfkill input line.
It has also a thermal protection circuitry that shuts down its transmitter if
the card overheats, and makes the status of that protection available (only for
reading!) to the kernel driver. This is also a hard rfkill input line.
If either one of these rfkill lines are active, the transmitter is blocked by
the hardware and forced offline.
The driver should allocate and attach to its struct device *ONE* instance of
the rfkill class (there is only one transmitter).
It can implement the get_state() hook, and return RFKILL_STATE_HARD_BLOCKED if
either one of its two hard rfkill input lines are active. If the two hard
rfkill lines are inactive, it must return RFKILL_STATE_SOFT_BLOCKED if its soft
rfkill input line is active. Only if none of the rfkill input lines are
active, will it return RFKILL_STATE_UNBLOCKED.
If it doesn't implement the get_state() hook, it must make sure that its calls
to rfkill_force_state() are enough to keep the status always up-to-date, and it
must do a rfkill_force_state() on resume from sleep.
Every time the driver gets a notification from the card that one of its rfkill
lines changed state (polling might be needed on badly designed cards that don't
generate interrupts for such events), it recomputes the rfkill state as per
above, and calls rfkill_force_state() to update it.
The driver should implement the toggle_radio() hook, that:
1. Returns an error if one of the hardware rfkill lines are active, and the
caller asked for RFKILL_STATE_UNBLOCKED.
2. Activates the soft rfkill line if the caller asked for state
RFKILL_STATE_SOFT_BLOCKED. It should do this even if one of the hard rfkill
lines are active, effectively double-blocking the transmitter.
3. Deactivates the soft rfkill line if none of the hardware rfkill lines are
active and the caller asked for RFKILL_STATE_UNBLOCKED.
===============================================================================
4: Kernel API
To build a driver with rfkill subsystem support, the driver should depend on
(or select) the Kconfig symbol RFKILL; it should _not_ depend on RKFILL_INPUT.
The hardware the driver talks to may be write-only (where the current state
of the hardware is unknown), or read-write (where the hardware can be queried
about its current state).
The rfkill class will call the get_state hook of a device every time it needs
to know the *real* current state of the hardware. This can happen often.
Some hardware provides events when its status changes. In these cases, it is
best for the driver to not provide a get_state hook, and instead register the
rfkill class *already* with the correct status, and keep it updated using
rfkill_force_state() when it gets an event from the hardware.
There is no provision for a statically-allocated rfkill struct. You must
use rfkill_allocate() to allocate one.
You should:
- rfkill_allocate()
- modify rfkill fields (flags, name)
- modify state to the current hardware state (THIS IS THE ONLY TIME
YOU CAN ACCESS state DIRECTLY)
- rfkill_register()
The only way to set a device to the RFKILL_STATE_HARD_BLOCKED state is through
a suitable return of get_state() or through rfkill_force_state().
When a device is in the RFKILL_STATE_HARD_BLOCKED state, the only way to switch
it to a different state is through a suitable return of get_state() or through
rfkill_force_state().
If toggle_radio() is called to set a device to state RFKILL_STATE_SOFT_BLOCKED
when that device is already at the RFKILL_STATE_HARD_BLOCKED state, it should
not return an error. Instead, it should try to double-block the transmitter,
so that its state will change from RFKILL_STATE_HARD_BLOCKED to
RFKILL_STATE_SOFT_BLOCKED should the hardware blocking cease.
Please refer to the source for more documentation.
===============================================================================
5: Userspace support
rfkill devices issue uevents (with an action of "change"), with the following
environment variables set:
RFKILL_NAME
RFKILL_STATE
RFKILL_TYPE
The ABI for these variables is defined by the sysfs attributes. It is best
to take a quick look at the source to make sure of the possible values.
It is expected that HAL will trap those, and bridge them to DBUS, etc. These
events CAN and SHOULD be used to give feedback to the user about the rfkill
status of the system.
Input devices may issue events that are related to rfkill. These are the
various KEY_* events and SW_* events supported by rfkill-input.c.
******IMPORTANT******
When rfkill-input is ACTIVE, userspace is NOT TO CHANGE THE STATE OF AN RFKILL
SWITCH IN RESPONSE TO AN INPUT EVENT also handled by rfkill-input, unless it
has set to true the user_claim attribute for that particular switch. This rule
is *absolute*; do NOT violate it.
******IMPORTANT******
Userspace must not assume it is the only source of control for rfkill switches.
Their state CAN and WILL change due to firmware actions, direct user actions,
and the rfkill-input EPO override for *_RFKILL_ALL.
When rfkill-input is not active, userspace must initiate a rfkill status
change by writing to the "state" attribute in order for anything to happen.
Take particular care to implement EV_SW SW_RFKILL_ALL properly. When that
switch is set to OFF, *every* rfkill device *MUST* be immediately put into the
RFKILL_STATE_SOFT_BLOCKED state, no questions asked.
The following sysfs entries will be created:
name: Name assigned by driver to this key (interface or driver name).
type: Name of the key type ("wlan", "bluetooth", etc).
state: Current state of the key. 1: On, 0: Off.
state: Current state of the transmitter
0: RFKILL_STATE_SOFT_BLOCKED
transmitter is forced off, but one can override it
by a write to the state attribute;
1: RFKILL_STATE_UNBLOCKED
transmiter is NOT forced off, and may operate if
all other conditions for such operation are met
(such as interface is up and configured, etc);
2: RFKILL_STATE_HARD_BLOCKED
transmitter is forced off by something outside of
the driver's control. One cannot set a device to
this state through writes to the state attribute;
claim: 1: Userspace handles events, 0: Kernel handles events
Both the "state" and "claim" entries are also writable. For the "state" entry
this means that when 1 or 0 is written all radios, not yet in the requested
state, will be will be toggled accordingly.
this means that when 1 or 0 is written, the device rfkill state (if not yet in
the requested state), will be will be toggled accordingly.
For the "claim" entry writing 1 to it means that the kernel no longer handles
key events even though RFKILL_INPUT input was enabled. When "claim" has been
set to 0, userspace should make sure that it listens for the input events or
check the sysfs "state" entry regularly to correctly perform the required
tasks when the rkfill key is pressed.
check the sysfs "state" entry regularly to correctly perform the required tasks
when the rkfill key is pressed.
A note about input devices and EV_SW events:
In order to know the current state of an input device switch (like
SW_RFKILL_ALL), you will need to use an IOCTL. That information is not
available through sysfs in a generic way at this time, and it is not available
through the rfkill class AT ALL.

This document and the new uhci sources can be found on
http://hotswap.in.tum.de/usb
1. General issues
1.1 Why a new UHCI driver, we already have one?!?
Correct, but its internal structure got more and more mixed up by the (still
ongoing) efforts to get isochronous transfers (ISO) to work.
Since there is an increasing need for reliable ISO-transfers (especially
for USB-audio needed by TS and for a DAB-USB-Receiver build by GA and DF),
this state was a bit unsatisfying in our opinion, so we've decided (based
on knowledge and experiences with the old UHCI driver) to start
from scratch with a new approach, much simpler but at the same time more
powerful.
It is inspired by the way Win98/Win2000 handles USB requests via URBs,
but it's definitely 100% free of MS-code and doesn't crash while
unplugging an used ISO-device like Win98 ;-)
Some code for HW setup and root hub management was taken from the
original UHCI driver, but heavily modified to fit into the new code.
The invention of the basic concept, and major coding were completed in two
days (and nights) on the 16th and 17th of October 1999, now known as the
great USB-October-Revolution started by GA, DF, and TS ;-)
Since the concept is in no way UHCI dependent, we hope that it will also be
transferred to the OHCI-driver, so both drivers share a common API.
1.2. Advantages and disadvantages
+ All USB transfer types work now!
+ Asynchronous operation
+ Simple, but powerful interface (only two calls for start and cancel)
+ Easy migration to the new API, simplified by a compatibility API
+ Simple usage of ISO transfers
+ Automatic linking of requests
+ ISO transfers allow variable length for each frame and striping
+ No CPU dependent and non-portable atomic memory access, no asm()-inlines
+ Tested on x86 and Alpha
- Rewriting for ISO transfers needed
1.3. Is there some compatibility to the old API?
Yes, but only for control, bulk and interrupt transfers. We've implemented
some wrapper calls for these transfer types. The usbcore works fine with
these wrappers. For ISO there's no compatibility, because the old ISO-API
and its semantics were unnecessary complicated in our opinion.
1.4. What's really working?
As said above, CTRL and BULK already work fine even with the wrappers,
so legacy code wouldn't notice the change.
Regarding to Thomas, ISO transfers now run stable with USB audio.
INT transfers (e.g. mouse driver) work fine, too.
1.5. Are there any bugs?
No ;-)
Hm...
Well, of course this implementation needs extensive testing on all available
hardware, but we believe that any fixes shouldn't harm the overall concept.
1.6. What should be done next?
A large part of the request handling seems to be identical for UHCI and
OHCI, so it would be a good idea to extract the common parts and have only
the HW specific stuff in uhci.c. Furthermore, all other USB device drivers
should need URBification, if they use isochronous or interrupt transfers.
One thing missing in the current implementation (and the old UHCI driver)
is fair queueing for BULK transfers. Since this would need (in principle)
the alteration of already constructed TD chains (to switch from depth to
breadth execution), another way has to be found. Maybe some simple
heuristics work with the same effect.
---------------------------------------------------------------------------
2. Internal structure and mechanisms
To get quickly familiar with the internal structures, here's a short
description how the new UHCI driver works. However, the ultimate source of
truth is only uhci.c!
2.1. Descriptor structure (QHs and TDs)
During initialization, the following skeleton is allocated in init_skel:
framespecific | common chain
framelist[]
[ 0 ]-----> TD --> TD -------\
[ 1 ]-----> TD --> TD --------> TD ----> QH -------> QH -------> QH ---> NULL
... TD --> TD -------/
[1023]-----> TD --> TD ------/
^^ ^^ ^^ ^^ ^^ ^^
1024 TDs for 7 TDs for 1 TD for Start of Start of End Chain
ISO INT (2-128ms) 1ms-INT CTRL Chain BULK Chain
For each CTRL or BULK transfer a new QH is allocated and the containing data
transfers are appended as (vertical) TDs. After building the whole QH with its
dangling TDs, the QH is inserted before the BULK Chain QH (for CTRL) or
before the End Chain QH (for BULK). Since only the QH->next pointers are
affected, no atomic memory operation is required. The three QHs in the
common chain are never equipped with TDs!
For ISO or INT, the TD for each frame is simply inserted into the appropriate
ISO/INT-TD-chain for the desired frame. The 7 skeleton INT-TDs are scattered
among the 1024 frames similar to the old UHCI driver.
For CTRL/BULK/ISO, the last TD in the transfer has the IOC-bit set. For INT,
every TD (there is only one...) has the IOC-bit set.
Besides the data for the UHCI controller (2 or 4 32bit words), the descriptors
are double-linked through the .vertical and .horizontal elements in the
SW data of the descriptor (using the double-linked list structures and
operations), but SW-linking occurs only in closed domains, i.e. for each of
the 1024 ISO-chains and the 8 INT-chains there is a closed cycle. This
simplifies all insertions and unlinking operations and avoids costly
bus_to_virt()-calls.
2.2. URB structure and linking to QH/TDs
During assembly of the QH and TDs of the requested action, these descriptors
are stored in urb->urb_list, so the allocated QH/TD descriptors are bound to
this URB.
If the assembly was successful and the descriptors were added to the HW chain,
the corresponding URB is inserted into a global URB list for this controller.
This list stores all pending URBs.
2.3. Interrupt processing
Since UHCI provides no means to directly detect completed transactions, the
following is done in each UHCI interrupt (uhci_interrupt()):
For each URB in the pending queue (process_urb()), the ACTIVE-flag of the
associated TDs are processed (depending on the transfer type
process_{transfer|interrupt|iso}()). If the TDs are not active anymore,
they indicate the completion of the transaction and the status is calculated.
Inactive QH/TDs are removed from the HW chain (since the host controller
already removed the TDs from the QH, no atomic access is needed) and
eventually the URB is marked as completed (OK or errors) and removed from the
pending queue. Then the next linked URB is submitted. After (or immediately
before) that, the completion handler is called.
2.4. Unlinking URBs
First, all QH/TDs stored in the URB are unlinked from the HW chain.
To ensure that the host controller really left a vertical TD chain, we
wait for one frame. After that, the TDs are physically destroyed.
2.5. URB linking and the consequences
Since URBs can be linked and the corresponding submit_urb is called in
the UHCI-interrupt, all work associated with URB/QH/TD assembly has to be
interrupt save. This forces kmalloc to use GFP_ATOMIC in the interrupt.

The symptom is that the eeprom cannot be read and the card is
unusable.
unusable. This is probably fixed, but if you have problems
then post to the video4linux or ivtv-users mailinglist.
3) The audio from the analog tuner is mono only. Probably caused by
incorrect audio register information in the datasheet. We are
waiting for updated information from Conexant.
