this patch allows to fully use a tape device connected to qemu through
the scsi-generic interface.
Previous patch introduced tape SCSI commands management, this one
improve error case management:
- the SCSI controller command completion must be called with the status
value, not the sense value. In the case of scsi-generic, the SCSI status
is given by the field status of sg_io_hdr_t (the value is left shifted
by one regarding status codes defined in /usr/include/scsi/scsi.h)
- when a read is aborted due to a mark/EOF/EOD/EOM, the len reported to
controller can be 0. LSI controller emulation doesn't know how to manage
this. A workaround found is to call the completion routine with
SCSI_REASON_DONE just after calling it with SCSI_REASON_DATA with len=0.
This patch also manages correctly the block size of the tape device.
This patch has been tested with a real tape device "HP C5683A", linux
guest (debian etch) and tools like "mt", "tar" and "btape".
Windows guest is not better supported than before...

This patch allows QEMUFile's read and write operations to return
negative error codes. This is necessary to detect things like closed

It also removes unused code for QEMUFileFD write path. Finally, it

is only being used for input. This was spotted by Uri Lublin.

The current flash emulation code advertises a write buffer size of 16
bytes (1 << 4, according to offset 0x2A of the CFI table). This is
very small compared to normal write buffer sizes, and makes the
process of writing to the flash very slow (at least from U-Boot).
This patch increases this size to 2048 bytes. Except the modification
of the CFI table, the only other required modification is to use
"value" instead of "cmd" to set pfl->counter, because cmd is truncated
to the 8 lower bits of value, while the number of bytes for a write
can now be greater than 255 bytes.

The current savevm/loadvm protocol has some draw backs. It does not support
the ability to do progressive saving which means it cannot be used for live
checkpointing or migration. The sections sizes are 32-bit integers which
means that it will not function when using more than 4GB of memory for a guest.
It attempts to seek within the output file which means it cannot be streamed.
The current protocol also is pretty lax about how it supports forward
compatibility. If a saved section version is greater than what the restore
code support, the restore code generally treats the saved data as being in
whatever version it supports. This means that restoring a saved VM on an older
version of QEMU will likely result in silent guest failure.
This patch introduces a new version of the savevm protocol. It has the
following features:
* Support for progressive save of sections (for live checkpoint/migration)
* An asynchronous API for doing save
* Support for interleaving multiple progressive save sections
(for future support of memory hot-add/storage migration)
* Fully streaming format
* Strong section version checking

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).

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

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

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 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.

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.

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.

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.

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.

Current key injection via the monitor basically generates no key hold
time. This is fine for keyboard emulations that have their own queues,
but it causes troubles for those how don't (like the MusicPal - it
simply does not work with injected keys). Moreover, I would like to use
this mechanism to simulate pressed buttons during power-up.
Therefore, this patch enhances the key injection with a configurable
release delay (by default 100 virtual milliseconds).
This feature allows to get rid of the initial sleep() in musicpal_init
because one can now simply start qemu with -S and issue "sendkey m 1000"
and "continue" in the monitor to achieve the desired effect of a pressed
menu button during power-up. So there is no need for a per-musicpal or
even qemu-wide "-hold-button" switch.

Apparently Windows Server 2003 sets the frequency for either mc or pi
voice to zero, which in turn triggers a call to audio_bug from this
chain:
open_voice -> AUD_open_in -> audio_bug (audio_validate_settings):
A bug was just triggered in AUD_open_in
...
Context:
audio: frequency=0 nchannels=2 fmt=S16 endianness=little
But since no attempt by the said OS is made to actually use the voice
with zero frequency this can be considered normal behavior.
Hence if zero freqency situation is encountered - close current voice,
and make noises if the guest tries to use it.

Previously, the BIOS would probe the CPUs for SMP guests. This tends to be
very unreliably because of startup timing issues. By passing the number of
CPUs in the CMOS, the BIOS can detect the number of CPUs much more reliably.

This patch fixes endianness issues in the e1000 nic emulation, which
currently only works on little endian hosts with little endian targets.
Byte swapping does not depend on host endianness, so this patch remove
the use of cpu_to_le32 and le32_to_cpu functions. It depends on the path
from the CPU to the device, which is currently and *wrongly* implemented
in Qemu as a byteswap on big endian targets. This patch does the same
as in other devices emulation as all the currently implemented targets
work with this implementation.

On big endian targets with mmio accesses, the values are not always

- Byte swapping for internal GT64XXX registers is controlled by the bit
12 of the Configuration Register and not by the PCI Internal Command
register.
- The bit 0 of the PCI Internal Command register controls byte swapping
for PCI access *except for the internal PCI device*, that is when both
bus and device numbers are 0.
