bdee56f546 tpm: reorganize headers and split hardware part
The TPM subsystem does not have a full front-end/back-end separation.
The sole available backend, tpm_passthrough, depends on the data
structures of the sole available frontend, tpm_tis.

However, we can at least try to split the user interface (tpm.c) from the
implementation (hw/tpm).  The patches makes tpm.c not include tpm_int.h,
which is shared between tpm_tis.c and tpm_passthrough.c; instead it
moves more stuff to tpm_backend.h.

aad64f3193 ide: refuse WIN_READ_NATIVE_MAX on empty device
What is the highest addressable sector on an empty CD-ROM?  Nothing is
addressable so produce an error.

This patch prevents a divide-by-zero in ide_set_sector() since
s->sectors and s->heads would be 0.  Not to mention that a sector=-1
argument would be nonsense.

Note that WIN_READ_NATIVE_MAX can be triggered using hdparm -N 1024
/dev/cdrom.  The LBA bit will be set to 1 though, so the only easy way
to go down the ide_set_sector() CHS code path which divides by zero is
to comment out the s->select & 0x40 case for testing.

fd7f8a99f3 pl330: Don't inhibit ES bits on INTEN
This if-else logic inhibits setting of the event status (ES) bits

regardless on INTEN state. INTEN only inhibits the signalling of

9246ce8811 Allow xen guests to plug disks of 1 TiB or more
The current xen backend driver implementation uses int64_t variables
to store the size of the corresponding backend disk/file. It also uses
an int64_t variable to store the block size of that image. When writing
the number of sectors (file_size/block_size) to xenstore, however, it
passes these values as 32 bit signed integers. This will cause an
overflow for any disk of 1 TiB or more.

This patch changes the xen backend driver to use a 64 bit integer write
xenstore function.

10bb3c6234 Introduce 64 bit integer write interface to xenstore
The current implementation of xen_backend only provides 32 bit integer
functions to write to xenstore. This patch adds two functions that
allow writing 64 bit integers (one generic function and another for
the backend only).

This patch also fixes the size of the char arrays used to represent
these integers as strings (originally 32 bytes, however no more than
12 bytes are needed for 32 bit integers and no more than 21 bytes are
needed for 64 bit integers).

c1a88ad1f4 Xen PV backend: Disable use of O_DIRECT by default as it results in crashes.
Due to what is almost certainly a kernel bug, writes with O_DIRECT may
continue to reference the page after the write has been marked as
completed, particularly in the case of TCP retransmit. In other
scenarios, this "merely" risks data corruption on the write, but with
Xen pages from domU are only transiently mapped into dom0's memory,
resulting in kernel panics when they are subsequently accessed.

This brings PV devices in line with emulated devices.  Removing
O_DIRECT is safe as barrier operations are now correctly passed
through.

See:

This commit delays the point at which bdrv_new (and hence blk_open

This ensures that in an inbound live migrate, the block device is
not opened until it has been closed at the other end. This is in
preparation for supporting devices with open/close consistency
without using O_DIRECT. This commit does NOT itself change O_DIRECT

e980f2bf0a acpi_table_add(): extract and reimplement internals
The new function acpi_table_install() installs any blob the caller passes
in. In the next patches this function will be promoted from helper role to
extern.

Reimplementing the logic should make it easier to understand. It also
removes a buffer overflow when

    has_header &&
    cumulative_file_size < ACPI_TABLE_HDR_SIZE - ACPI_TABLE_PFX_SIZE

(In that case the g_realloc() call in the read() loop used to shrink the
"acpi_tables" array, causing an out-of-bounds read access when copying the
header out of "acpi_tables".)

The new code isn't more daring alignment-wise than its predecessor:
"acpi_table_header" is packed, and the uint32_t fields are at offsets 6,
26, and 34.

7076eabcbf qemu vfio-pci: Graphics device quirks
Graphics cards have a number of different backdoors.  Some of these
are alternative ways to get PCI BAR addresses, some of them are
complete mirrors of PCI config space available through MMIO and
I/O port access.  These quirks cover a number of ATI Radeon and
Nvidia devices.  On the ATI/AMD side, this should enable HD5450
and HD7850 and hopefully a host of devices around those generations.
For Nvidia, my card selection is much more dated.  A 8400gs works
well with both the Window shipped driver and the Nvidia downloaded
driver.  A 7300le works as well, with the caveat that generating
the Window experience index with the Nvidia driver causes the card
to reset several times before generating a BSOD.  An NVS 290 card
seems to run well with the shipped Windows driver, but generates
a BSOD with the Nvidia driver.  All of the Nvidia devices work with
the Linux Nvidia proprietary driver and nouveau, the HD5450 works
with either radeon or fglrx, HD7850 works with vesa and fglrx (not
supported by radeon).  Extremely limited 3D testing.

Device reset is also an issue with graphics.  It's unfortunately
very common that the devices offer no means to reset the card or
doesn't seem effective.  Nvidia devices are pretty good about being
able to get the device to a working state through the VGA BIOS init,
Radeon devices less so, and often require a host reboot.  Work
remains to be done here.

f15689c7e4 qemu vfio-pci: Add support for VGA MMIO and I/O port access
Most VGA cards need some kind of quirk to fully operate since they
hide backdoors to get to other registers outside of PCI config space
within the registers, but this provides the base infrastructure.  If
we could identity map PCI resources for assigned devices we would need
a lot fewer quirks.

To enable this, use a kernel side vfio-pci driver that incorporates
VGA support (v3.9), and use the -vga none option and add the x-vga=on
option for the vfio-pci device.  The "x-" denotes this as an
experimental feature.  You may also need to use a cached copy of the
VGA BIOS for your device, passing it to vfio-pci using the romfile=
option.

96adc5c7c2 vfio-pci: Add PCIe capability mangling based on bus type
Windows seems to pay particular interest to the PCIe header type of
devices and will fail to load drivers if we attach Endpoint devices or
Legacy Endpoint devices to the Root Complex.  We can use
pci_bus_is_express and pci_bus_is_root to determine the bus type and
mangle the type appropriately:

* Legacy PCI
  * No change, capability is unmodified for compatibility.
* PCI Express
  * Integrated Root Complex Endpoint -> Endpoint
* PCI Express Root Complex
  * Endpoint -> Integrated Root Complex Endpoint
  * Legacy Endpoint -> none, capability hidden

We also take this opportunity to explicitly limit supported devices
to Endpoints, Legacy Endpoints, and Root Complex Integrated Endpoints.
We don't currently have support for other types and users often cause
themselves problems by assigning them.

4b5d5e87c7 vfio-pci: Generalize PCI config mangling
Kernel-side vfio virtualizes all of config space, but some parts are
unique to Qemu.  For instance we may or may not expose the ROM BAR,
Qemu manages MSI/MSIX, and Qemu manages the multi-function bit so that
single function devices can appear as multi-function and vica versa.
Generalize this into a bitmap of Qemu emulated bits.

e63d28d7db sysbus: Remove sysbus_add_memory and sysbus_del_memory
Remove the sysbus_add_memory and sysbus_del_memory functions. These
are trivial wrappers for mapping a memory region into the system
memory space, and have no users now.  Sysbus devices should never map
their own memory regions anyway; the correct API for mapping an mmio
region is for the creator of the device to use sysbus_mmio_map.

Don't map the pmem and dmem RAM memory regions in the milkymist-softusb

the device creator can map appropriately. This allows us to drop the

bc6b815d9e virtio-serial: propagate guest_connected to the port on post_load
When migrating a host with with a spice agent running the mouse becomes
non operational after the migration due to the agent state being
inconsistent between the guest and the client.

After migration the spicevmc backend on the destination has never been notified
of the (non 0) guest_connected state. Virtio-serial holds this state
information and migrates it, this patch properly propagates this information
to virtio-console and through that to interested chardev backends.

pci_bridge_dev_map_irq_fn() is identical to pci_swizzle_map_irq_fn(),
which is now the default for all PCI bridges.  We can therefore remove
this function and the pci_bridge_map_irq() call that used it.

659fefeed3 pci_bridge: Use a default map_irq function
The PCI bridge spec defines a default swizzle for translating INTx
IRQs from secondary bus to primary.  Use this by default for any
bridge that doesn't set a function.

e5368f0da7 pci: Fix INTx routing notifier recursion
For some reason we recurse to fire the INTx routing notifier for each
child of a bus, for each possible device of a bus.  That means that if
we add a root port, the notifier gets called for that bridge 256
times.  If we add an upstream switch behind that root port, 256^2.  But
of course we need a downstream switch, 256^3.  This starts to be
noticeable.  Stop the insanity.

600d05b9aa pci_bridge: drop formatting from source
We use the same formatting for all files, it
doesn't make sense to have formatting directives only
in pci bridge header.

45eb768c70 pci_bridge: factor out common code
Reuse common code in pcie_port, override the hardwired-to-0
bits per PCI Express spec.
No functional change but makes the code easier to follow.

ba7d8515c1 pci: Teach PCI Bridges about VGA routing
Each PCI Bridge has a set of implied VGA regions that are enabled when
the VGA bit is set in the bridge control register.  This allows VGA
devices behind bridges.  Unfortunately with VGA Enable, which we
formerly allowed but didn't back, comes along some required VGA
baggage.  VGA Palette Snooping is required, along with VGA 16-bit
decoding.  We don't yet have support for palette snooping.
We also don't have support for 10-bit VGA aliases, the default mode, but
we enable the register, even on root ports, to avoid confusing guests.
Fortunately there's likely nothing from this century that requires these
features, so the missing bits are noted with TODOs.

e01fd68718 pci: Add PCI VGA helpers
Allow devices to register VGA memory regions for handling PCI spec
defined VGA I/O port and MMIO areas.  PCI will attach these to the
bus address spaces and enable them according to the device command
register value.

a38b2c49bf virtio-pci: guest notifier mask without non-irqfd
non-irqfd setups are currently broken with vhost:
we start up masked and nothing unmasks the interrupts.
Fix by using mask notifiers, same as the irqfd path.

Sharing irqchip/non irqchip code is always a good thing,
in this case it will help non irqchip benefit
from backend masking optimization.
