The IDE PIO write sector code path uses bdrv_write() and hence can make
the guest unresponsive while the I/O request is in progress. This patch
converts ide_sector_write() to use bdrv_aio_writev() by using the
BUSY_STAT bit to tell the guest that the request is in progress.

The IDE PIO interface currently uses bdrv_read() to perform reads
synchronously. Synchronous I/O in the vcpu thread is bad because it
prevents the guest from executing code - it makes the guest
unresponsive.
This patch converts IDE PIO to use bdrv_aio_readv(). We simply need to
use the BUSY_STAT status so the guest knows to wait while we are busy.
The only external user of ide_sector_read() is restart behavior on I/O
errors and it is not affected by this change. We still need to restart
I/O in the same way.
Migration is also unaffected if I understand the code correctly. We
continue to use the same transfer function and the BUSY_STAT status
should never be migrated since we flush I/O before migrating device
state.

Adding multiqueue is as simple as creating more than one virtqueues,
and saving the queue number for each request.
Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
Serializing virtio-scsi requests needs a simple way to get from a
VirtQueue to the number of the queue. The virtio_queue_get_id
provides this.
Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
In order to restore requests correctly from a multitude of virtqueues,
we need to store the id of the request queue that each request came
from.
Do this even for single-queue, by storing a hard-coded zero, to
simplify future implementation of multiqueue.

The addition of those values caused a regression where not specifying
any value for the vram bar size would result in a 4096 _byte_ surface
area. This is ok for the windows driver but causes the X driver to be

Not sure what the purpose of the assert() was, in any case it is bogous.
We can arrive there if transfer descriptors passed to us from the guest
failed to pass sanity checks, i.e. it is guest-triggerable. We deal

This patch carries a complete rewrite of the usb descriptor parser.
Changes / improvements:
* We are using the USBDescriptor struct instead of hard-coded offsets
now to access descriptor data.
* (debug) printfs are all gone, tracepoints have been added instead.
* We don't try (and fail) to skip over unneeded descriptors. We parse
them all one by one. We keep track of which configuration, interface
and altsetting we are looking at and use this information to figure
which desciptors are in use and which we can ignore.
* On parse errors we clear all endpoint information, which will
disallow any communication with the device, except control endpoint
messages. This makes sure we don't end up with a silly device state
where half of the endpoints got enabled and the other half was left
disabled.
* Some sanity checks have been added.
The new parser is more robust and also leaves complete device
information in the trace log if you enable the ush_host_parse_*
tracepoints.

frindex always is a 14 bits counter, and not a 13 bits one as we were
emulating. There are some subtle hints to this in the spec, first of all
"Table 2-12. FRINDEX - Frame Index Register" says:
"Bit 13:0 Frame Index. The value in this register increments at the end of
each time frame (e.g. micro-frame). Bits [N:3] are used for the Frame List
current index. This means that each location of the frame list is accessed
8 times (frames or micro-frames) before moving to the next index. The
following illustrates values of N based on the value of the Frame List
Size field in the USBCMD register.
USBCMD[Frame List Size] Number Elements N
00b 1024 12
01b 512 11
10b 256 10
11b Reserved"
Notice how the text talks about "Bits [N:3]" are used ..., it does
NOT say that when N == 12 (our case) the counter will wrap from 8191 to 0,
or in otherwords that it is a 13 bits counter (bits 0 - 12).
The other hint is in "Table 2-10. USBSTS USB Status Register Bit Definitions":
"Bit 3 Frame List Rollover - R/WC. The Host Controller sets this bit to a one
when the Frame List Index (see Section 2.3.4) rolls over from its maximum value
to zero. The exact value at which the rollover occurs depends on the frame
list size. For example, if the frame list size (as programmed in the Frame
List Size field of the USBCMD register) is 1024, the Frame Index Register
rolls over every time FRINDEX[13] toggles. Similarly, if the size is 512,
the Host Controller sets this bit to a one every time FRINDEX[12] toggles."
Notice how this text talks about setting bit 3 when bit 13 of frindex toggles
(when there are 1024 entries, so our case), so this indicates that frindex
has a bit 13 making it a 14 bit counter.
Besides these clear hints the real proof is in the pudding. Before this
patch I could not stream data from a USB2 webcam under Windows XP, after
this cam using a USB2 webcam under Windows XP works fine, and no regressions
with other operating systems were seen.
