cards: the chips are all marked "RTL8111B", but they put stickers on the
back that say "RTL8168B/8111B". The manual says there's only one HWREV code
for both the 8111B and 8168B devices, which is 0x30000000, but the cards
they sent me actually report HWREV of 0x38000000. Deciding to trust the
hardware in front of me rather than a possibly incorrect manual (it wouldn't
be the first time the HWREVs were incorrectly documented), I changed the
8168 revision code. It turns out this was a mistake though: 0x30000000
really is a valid for the 8168.
There are two possible reasons for there to be two different HWREVs:
1) 0x30000000 is used only for the 8168B and 0x38000000 is only for
the 8111B.
2) There were 8111/8168 rev A devices which both used code 0x30000000,
and the 8111B/8168B both use 0x38000000.
The product list on the RealTek website doesn't mention the existence of
any 8168/8111 rev A chips being in production though, and I've never seen
one, so until I get clarification from RealTek, I'm going to assume that
0x30000000 is just for the 8168B and 0x38000000 is for the 8111B only.
So, the HWREV code for the 8168 has been put back to 0x30000000,
a new 8111 HWREV code has been added, and there are now separate
entries for recognizing both devices in the device list. This will
allow all devices to work, though if it turns out I'm wrong I may
need to change the ID strings
latter is a PCIe 10/100 chip.
Finally fix the EEPROM reading code so that we can access the EEPROMs on all
devices. In order to access the EEPROM, we must select 'EEPROM programming'
mode, and then set the EEPROM chip select bit. Previously, we were setting
both bits simultaneously, which doesn't work: they must be set in the
right sequence.
Always obtain the station address from the EEPROM, now that EEPROM
reading works correctly.
Make the TX interrupt moderation code based on the internal timer
optional and turned off by default.
Make the re_diag() routine conditional and off by default. When it is
on, only use it for the original 8169, which was the only device that
that really needed it.
Modify interrupt handling to use a fast interrupt handler and fast
taskqeueue.
Correct the rgephy driver so that it only applies the DSP fixup for
PHY revs 0 and 1. Later chips are fixed and don't need the fixup.
Make the rgephy driver advertise both 1000_FD and 1000_HD bits in
autoneg mode. A couple of the devices don't autoneg correctly unless
configured this way.
capability is present as not all devices supported by the agp_i810 driver
(such as i915) have the AGP capability. Instead, add an identify routine
to the agp_i810 driver that uses the PCI ID to determine if it should
create an agp child device.
if we need a valid MAC address (for probing the media for example) before
ether_ifattach() has been called since IF_LLADDR() is NULL then.

the addition of pci_find_extcap().
- Change the drm drivers to attach to vgapci. This is #ifdef'd so the
code can be shared across branches.
- Use pci_find_extcap() to look for AGP and PCIE capabilities in drm.
- GC all the drmsub stuff for i810/i830/i915. The agp and drm devices are
now both children of vgapci.
attach to the hostb driver instead. This means that agp can now be loaded
at runtime (in theory at least). Also, the drivers no longer have to
explicity call device_verbose() to cancel out any earlier calls to
device_quiet() by the hostb(4) driver (this shows a limitation in new-bus,
drivers really shouldn't be doing device_quiet() until they know they are
going to drive that device, i.e. in attach).
drivers already map sections into KVA as needed anyway. Note that this
will probably break the nvidia driver, but I will coordinate to get that
fixed.

AMD-8111 SMBus 2.0 controller) are all SMBus 2.0 controllers,

this driver supports AMD-756 SMBus 1.0 controller and clones,
including AMD-8111 SMBus 1.0 controller.

All of us got the same(!) nonsense when running ``mbmon -S'',
repeated every four rows.
SMBus 1.0 and not SMBus 2.0.
AMD-8111 hub (datasheet is publically available) implements both SMBus
2.0 (a separate PCI device) and SMBus 1.0 (a subfunction of the System
Management Controller device with the base I/O address is accessible
through the CSR 0x58). This driver only supports AMD-756 SMBus 1.0
compatible devices.
With the patched sysutils/xmbmon port (to also fix PCI ID and to enable
smb(4) support), I now get:
pciconf:

I think the confusion comes from the fact that nobody really tried
SMBus with xmbmon :-), since sysutils/xmbmon port doesn't come with
SMBus support enabled, neither in FreeBSD 4, nor in later versions,
so mbmon(1) was just showing the values from the Winbond sensors
accessible through the ISA I/O method (mbmon -I), for me anyway.
On my test machine, the amdpm(4) didn't even attach due to I/O port
allocation failure (who knows what the hell it read from CSR 0x58
of the SMBus 2.0 device :-), which isn't in the CSR space).
I've also checked that lm_sensors.org uses correct PCI ID for SMBus
1.0 of AMD-8111:
i2c-amd756.c: {PCI_VENDOR_ID_AMD, 0x746B, PCI_ANY_ID, PCI_ANY_ID, 0, 0, AMD8111 },
This driver is analogous to our amdpm.c which supports SMBus 1.0
AMD-756 and compatible devices, including SMBus 1.0 on AMD-8111.
i2c-amd8111.c: { 0x1022, 0x746a, PCI_ANY_ID, PCI_ANY_ID, 0, 0, 0 },
This driver is analogous to nForce-2/3/4, i2c-nforce2.c, which
supports SMBus 2.0, and which our amdpm.c does NOT support
(SMBus 2.0 uses a different, ACPI-unified, API to talk to SMBus).
At least I know for sure it doesn't work with my nForce3. :-)
(The xmbmon port will be fixed to correct the PCI ID too and to
enable the smb(4) support.)
SMBus busses. Because of limitations in smbus_if.m, the second smbus is
attached to an amdpm1 device that is a child of amdpm0.

and some fixes from Motomichi Matsuzaki. Testing involved many people, but the
final, successful testing was from rwatson who endured several rounds of "it
crashes at XYZ stage" "oh, please correct this typo and try again." The Linux
driver, and to a small extent the limited specs, were both used as a reference
for how to program the chipset.

- Don't call tulip_addr_filter() to reset the RX address filter in
tulip_reset() since that gets called before ether_ifattach(). Just
call it in tulip_init_locked().
- Use be16dec() and le16dec() to parse MAC addresses when programming
the RX filter.
- Let ether_ioctl() handle SIOCSIFMTU since we were doing the exact same
thing with the added bonus that we leaked the driver lock if the MTU
was > ETHERMTU in the homerolled version. This part will be MFC'd.

rather than in ifindex_table[]; all (except one) accesses are
through ifp anyway. IF_LLADDR() works faster, and all (except
one) ifaddr_byindex() users were converted to use ifp->if_addr.
- Stop storing a (pointer to) Ethernet address in "struct arpcom",
and drop the IFP2ENADDR() macro; all users have been converted
to use IF_LLADDR() instead.
PCI-ISA bridge. Thus, when viapm0 or viapropm0 attaches, isab0 dosen't
attach so there is no isa0 bus hung off of that bridge. In the non-ACPI
case, legacy0 will add an isa0 anyway as a fail-safe, but ACPI assumes that
any ISA bus will be enumerated via a bridge. To fix this, call
isab_attach() to attach an isa0 ISA child bus device if the pm or propm
device we are probing is a PCI-ISA bridge. Both drivers now have to
implement the bus_if interface via the generic methods for resource
allocation, etc. to work. Also, we now add 2 new ISA bus drivers that
attach to viapm and viapropm devices.

- Use callout_*() to manage callout.
- Test IFF_DRV_RUNNING rather than IFF_UP in wb_intr() to see if we are
still active when an interrupt comes in.
I couldn't find any of these cards anywhere to test on myself, and google
turns up references to FreeBSD and OpenBSD manpages for this driver when
trying to locate a card that way. I'm not sure anyone actually uses these
cards with FreeBSD.
