a9dd6843be scsi-generic: decode correctly SCSI tape commands (Laurent Vivier)
This patch allows to use a "real" SCSI tape with qemu using
"-drive /dev/sgX,if=scsi".

It allows to decode correctly transfer length when the type of the
device is a tape.

Some issues remain when the application reading the tape tries to go
beyond the end of the stream (but they must be corrected at the SCSI
controller level).

ee4d919f30 LSI SCSI: raise UDC on infinite loop (Marcelo Tosatti)
Raise UDC (Unexpected Disconnect) when a large enough number of
instructions has been executed by the SCRIPTS processor. This "solution"
is much simpler than temporarily interrupting execution.

This remedies the situation with Windows which downloads SCRIPTS code
that busy loops on guest main memory. Their drivers _do_ handle UDC 
appropriately (at least XP and 2003).

It would be nicer to actually detect infinite loops, but until then,
this bandaid seems acceptable.

Since the situation seems to be rare enough, raise the number 
of instructions to 10000 (previously 1000).

Three people other than myself had success with this patch.

5628a6260a 16550A UART: RHR irq enable bit also masks the Rx timeout irq.
The "Rx timeout" (aka. Character Timeout Indication) has no separate mask
bit in the IER register and according to the specs reading RHR is the only
way to reset the irq.  However on the hardware (tested on OMAP2 UART which
is an extended 16550A) the RHR_IT bit in IER disables the irc, too.  Linux
bluetooth serial dongle driver for N800 depends on this behavior.

82b36dc398 Right now, kvm keeps the memory allocation split, so we can

This patch proposes using this common ground for everyone, by spliting
raw qemu.

5d0c5750bb usb: Support for removing device by host addr, improved auto filter syntax (Max Krasnyansky)
This patch adds support for removing USB devices by host address.
Which is usefull for things like libvirtd because there is no easy way to
find guest USB address of the host device.
In other words you can now do:
   usb_add host:3.5
   ...
   usb_del host:3.5
Before the patch 'usb_del' did not support 'host:' notation.

----
Syntax for specifying auto connect filters has been improved.
Old syntax was
    host:bus.dev
    host:pid:vid
New syntax is
    host:auto:bus.dev[:pid:vid]
In both the cases any attribute can be set to "*".

New syntax is more flexible and lets you do things like
    host:3.*:5533:* /* grab any device on bus 3 with vendor id 5533 */

It's now possible to remove auto filters. For example:
    usb_del host:auto:3.*:5533:*

Active filters are printed after all host devices in 'info usb' output.
Which now looks like this:

  Device 1.1, speed 480 Mb/s
    Hub: USB device 1d6b:0002, EHCI Host Controller
  Device 1.4, speed 480 Mb/s
    Class 00: USB device 1058:0704, External HDD
  Auto filters:
    Device 3.* ID *:*

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.

0fd3ca30c4 sh4: CPU versioning.
Trivial patch adding CPU listing and the ability to do per-subtype
CVR/PVR/PRR values. Presently SH7750R and SH7751R definitions are
provided, as these are the ones in present use in-tree.

The CVR value for SH7751R is intentionally restricted so the kernel
boots, though this will want to be switched to the proper CVR value
once system emulation has sufficiently stabilized.

This also makes it trivial to abstract subtype specific registers like
MMU_PTEA and to set up feature bits in line with the kernel probing for
things like conditionalizing FPU/DSP context.

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.

06afe2c884 [sh4] MMU bug fix
Some bugs on SH4 MMU are fixed.

- When a TLB entry is overwritten or invalidated, tlb_flush_page() should be
  invoked to invalidate old entry.
- When a ASID is changed, tlb_flush() should be invoke to invalidate entries
  which have old ASID.
- The check for shared bit in TLB entry causes multiple TLB hit exception.
  As SH3's MMU, shared bit is ignored.
- ASID is used when MMUCR's SV bit or SR's MD bit is zero.
  No need to check both bits are zero.

The direction bit in the control register should not be directly

set using PPWCONTROL. The kernel gives the following debug message.

    parport0 (ppdev0): use data_reverse for this!

More over setting the data pins to forward mode does not work,
perhaps a bug in the Linux PP driver. The right way to do this is
to use PPDATADIR to set the direction. The patch checks if the
user is toggling the direction bit, and invokes PPDATADIR to
do the job.

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.

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.

4b096fc9ec husb: support for USB host device auto connect (Max Krasnyansky)
QEMU can now automatically grab host USB devices that match the filter.
For now I just extended 'host:X.Y' and 'host:VID:PID' syntax to handle
wildcards. So for example if you do something like
   usb_add host:5.*
QEMU will automatically grab any non-hub device with host address 5.*.

Same with the 'host:PID:*', we grab any device that matches PID.

Filtering itself is very generic so we can probably add more elaborate
syntax like 'host:BUS.ADDR:VID:PID'. So that we can do 'host:5.*:6000:*'.

Anyway, it's implemented using a periodic timer that scans host devices
and grabs those that match the filter. Timer is started when the first
filter is added.

We now keep the list of all host devices that we grabbed to make sure that
we do not grab the same device twice.

btw It's currently possible to grab the same host device more than once.
ie You can just do "usb_add host:1.1" more than once, which of course does
not work. So this patch fixes that issue too.

Along with auto disconnect patch that I send a minute ago the setup is very
seamless now. You can just allocate some usb ports to the VMs and plug/unplug
devices at any time.

1f3870ab24 husb: support for USB host device auto disconnect (Max Krasnyansky)
I got really annoyed by the fact that you have to manually do
usb_del in the monitor when host device is unplugged and decided
to fix it :)

Basically we now automatically remove guest USB device
when the actual host device is disconnected.

At first I've extended set_fd_handlerX() stuff to support checking
for exceptions on fds. But unfortunately usbfs code does not wake up
user-space process when device is removed, which means we need a
timer to periodically check if device is still there. So I removed
fd exception stuff and implemented it with the timer.
