PPC: tell the guest about the time base frequency

Our guest systems need to know by how much the timebase increases every second,
so there usually is a "timebase-frequency" property in the cpu leaf of the
device tree.

This property is missing in OpenBIOS.

With qemu, Linux's fallback timebase speed and qemu's internal timebase speed
match up. With KVM, that is no longer true. The guest is running at the same
timebase speed as the host.

This leads to massive timing problems. On my test machine, a "sleep 2" takes
about 14 seconds with KVM enabled.

This patch exports the timebase frequency to OpenBIOS, so it can then put them

Add three new qdev properties to export block topology information to
the guest.  This is needed to get optimal I/O alignment for RAID arrays
or SSDs.

The options are:

 - physical_block_size to specify the physical block size of the device,
   this is going to increase from 512 bytes to 4096 kilobytes for many
   modern storage devices
 - min_io_size to specify the minimal I/O size without performance impact,

 - opt_io_size to specify the optimal sustained I/O size, this is
   typically the RAID stripe width for arrays.

I decided to not auto-probe these values from blkid which might easily
be possible as I don't know how to deal with these issues on migration.

Note that we specificly only set the physical_block_size, and not the
logial one which is the unit all I/O is described in.  The reason for
that is that IDE does not support increasing the logical block size and
at last for now I want to stick to one meachnisms in queue and allow
for easy switching of transports for a given backing image which would
not be possible if scsi and virtio use real 4k sectors, while ide only
uses the physical block exponent.

To make this more common for the different block drivers introduce a
new BlockConf structure holding all common block properties and a

the ones in these files:

  block/curl.c
  net.c
  slirp/misc.c

and the first one in block/vvfat.c.
The others in block/vvfat.c may not lead to an immediate segfault, but I
traced the two schedule_rename(..., strdup(path)) uses, and a failed
strdup would appear to trigger this assertion in handle_renames_and_mkdirs:

    assert(commit->path);

The conversion to use qemu_strdup in envlist_to_environ is not technically
needed, but does avoid a theoretical leak in the caller when strdup fails
for one value, but later succeeds in allocating another buffer(plausible,
if one string length is much larger than the others).  The caller does
not know the length of the returned list, and as such can only free
pointers until it hits the first NULL.  If there are non-NULL pointers
beyond the first, their buffers would be leaked.  This one is admittedly
far-fetched.

The two in linux-user/main.c are worth fixing to ensure that an
OOM error is diagnosed up front, rather than letting it provoke some
harder-to-diagnose secondary error, in case of exec failure, or worse, in
case the exec succeeds but with an invalid list of command line options.
However, considering how unlikely it is to encounter a failed strdup early
in main, this isn't a big deal.  Note that adding the required uses of
qemu_strdup here and in envlist.c induce link failures because qemu_strdup

However, we still have not fully converted handlers using

14 years agoaudio streaming from usb devices
David S. Ahern [Wed, 3 Feb 2010 15:49:39 +0000 (08:49 -0700)]
audio streaming from usb devices

I have streaming audio devices working within qemu-kvm. This is a port
of the changes to qemu.

Streaming audio generates a series of isochronous requests that are
repetitive and time sensitive. The URBs need to be submitted in
consecutive USB frames and responses need to be handled in a timely manner.

Summary of the changes for isochronous requests:

1. The initial 'valid' value is increased to 32. It needs to be higher
than its current value of 10 since the host adds a 10 frame delay to the
scheduling of the first request; if valid is set to 10 the first
isochronous request times out and qemu cancels it. 32 was chosen as a
nice round number, and it is used in the path where a TD-async pairing
already exists.

2. The token field in the TD is *not* unique for isochronous requests,
so it is not a good choice for finding a matching async request. The
buffer (where to write the guest data) is unique, so use that value instead.

3. TD's for isochronous request need to be completed in the async
completion handler so that data is pushed to the guest as soon as it is
available. The uhci code currently attempts to process complete
isochronous TDs the next time the UHCI frame with the request is
processed. The results in lost data since the async requests will have
long since timed out based on the valid parameter. Increasing the valid
value is not acceptable as it introduces a 1+ second delay in the data
getting pushed to the guest.

4. The frame timer needs to be run on 1 msec intervals. Currently, the
expire time for the processing the next frame is computed after the
processing of each frame. This regularly causes the scheduling of frames
to shift in time. When this happens the periodic scheduling of the
requests is broken and the subsequent request is seen as a new request
by the host resulting in a 10 msec delay (first isochronous request is
scheduled for 10 frames from when the URB is submitted).

[ For what's worth a small change is needed to the guest driver to have
more outstanding URBs (at least 4 URBs with 5 packets per URB).]
