blueswir1 173a543b36 Add and use #defines for PCI device classes
This patch adds and uses #defines for PCI device classes and subclases,
using a new pci_config_set_class() function, similar to the recently
added pci_config_set_vendor_id() and pci_config_set_device_id().

Change since v1: fixed compilation of hw/sun4u.c

aliguori deb54399df Define PCI vendor and device IDs in pci.h (Stuart Brady)
This patch defines PCI vendor and device IDs in pci.h (matching those
from Linux's pci_ids.h), and uses those definitions where appropriate.

Change from v1:
  Introduces pci_config_set_vendor_id() / pci_config_set_device_id()
  accessors as suggested by Anthony Liguori.

aliguori a145ea5120 uhci: Change default transaction lifetime to 32 frames (Max Krasnyansky)
Transaction lifetime was originally set to 10 frames. That was an arbitrary
number I picked without much thinking :).
I'm changing that to 32 frames because things like interrupt transfers
and such are scheduled at that rate. It seems like 1/32 is accepted as
lowest supported rate. OHCI, for example, defines exactly 32 interrupt
heads.

While testing USB webcam under XP I noticed that interrupt transactions were
being canceled and then resubmitted on a regular basis, which works but is a
waste of CPU cycles. This change fixes that.
All other devices I have are not affected.

aurel32 e8ee3c7276 uhci: improved TD matching, working ISOC transfers
While trying to make VX-3000 camera work on XP under KVM I realized that
we do not necessarily have to find original TD address. All we care about
is the token which identifies the transfer rather well (direction, endpoint,
size, etc).
This is especially important for the isochronous transfers because otherwise
they are being canceled left and right and we do not make much progress.

With this patch all devices that used bulk transfers that I've tried so
far continue to work just as well. And now my USB web cammera (isoc transfers)
is working well tool. It's not as smooth as native Windows but it's pretty
darn smooth.

The cool thing is that new USB code (both usb-uhci and usb-linux) is totaly
generic and does not need any special logic for ISOC.

aliguori 6f382b5ec0 uhci: fixes for save/load-vm (Max Krasnyansky)
For some reason we were not registering save/load-vm handler for piix3
flavor of UHCI and hence save/load was broken.

Async transactions need to be canceled when we save the VM because there
is no way we can save/restore all that state. Since we do not mess the
original TD/QH the driver will simply resubmit the transfers.

Tested with Windows XP-SP2 running under QEMU/KQEMU.

aliguori 54f254f973 uhci: rewrite UHCI emulator, fully async operation with multiple outstanding transactions (Max Krasnyansky)
This is esentially a re-write of the QEMU UHCI layer. My initial goal
was to support fully async operation with multiple outstanding async
transactions. Along the way I realized that I can greatly simplify
and cleanup the overall logic. There was a lot of duplicate and confusing
code in the UHCI data structure parsing and other places.
We were actually violating UHCI spec in handling async ISOC transaction
(host controller is not supposed to write into the frame pointer).

The reason I wanted to support fully async operation is because current
synchronous version is unusable with most devices exported from host
(via usb-linux.c). Transactions take a long time and the whole VM becomes
slow as hell.

Current async support is very rudimentory and for the most part
non-functional. Single transaction at a time is simply not enough. I have
a device for which XP driver submits both IN and OUT packets at the same
time. IN packet always times out unless OUT packet makes it to the device.
Hence we must be able to process both in order for that device to work.

The new code is backwards compatible and was first tested agains original
synchronous usb-linux.c and builtin usb devices like tablet which is also
synchronous. Rewrite of the usb-linux.c is coming up next.

Async support was tested against various XP versions (ie XP, SP2, SP3) and
a bunch of different USB devices: serial port controllers, mice, keyboard,
JTAG dongles (from Xilinx and Altera).

ISOC support was only lighly tested and needs more work. It's not any worse
than current code though.

UHCI parser changes are probably somewhat hard to review without the
understanding of the UHCI spec.
The async design should be fairly easy to follow. Basically we have a list
of async objects for each pending transfer. Async objects are tagged with
the original TD (transfer descriptor) address and token. We now support
unlimited number of outstanding isoc and one outstanding bulk/intr/ctrl
transfer per QH (queue head). UHCI spec does not have a clear protocol for
the cancelation of the trasfer requests. Driver can yank out TDs on any
frame boundary. In oder to handle that I added somewhat fancy TD validation
logic logic to avoid unnecessary cancelations.
