2009-09-09qdev/usb: make qemu aware of usb busses.Gerd Hoffmann1-2/+5
Move usb code from vl.c to usb-bus.c and make it use the new data structures added by qdev conversion. qemu usb core should be able to handle multiple USB busses just fine now (untested though). Kill some usb_*_init() legacy functions, use usb_create_simple() instead. Kill some FIXMEs added by the first qdev/usb patch.

2008-09-11uhci: Change default transaction lifetime to 32 frames (Max Krasnyansky)aliguori1-1/+1
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.

2008-08-22uhci: improved TD matching, working ISOC transfersaurel321-12/+28
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.

2008-08-21uhci: fixes for save/load-vm (Max Krasnyansky)aliguori1-2/+8
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.

2008-08-21uhci: rewrite UHCI emulator, fully async operation with multiple outstanding ↵aliguori1-364/+533
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.
