2018-03-13iotests: add dirty bitmap migration testVladimir Sementsov-Ogievskiy
The test starts two vms (vm_a, vm_b), create dirty bitmap in the first one, do several writes to corresponding device and then migrate vm_a to vm_b. Signed-off-by: Vladimir Sementsov-Ogievskiy <vsementsov@virtuozzo.com> Message-id: 20180313180320.339796-13-vsementsov@virtuozzo.com
2018-03-13migration: add postcopy migration of dirty bitmapsVladimir Sementsov-Ogievskiy
Postcopy migration of dirty bitmaps. Only named dirty bitmaps are migrated. If destination qemu is already containing a dirty bitmap with the same name as a migrated bitmap (for the same node), then, if their granularities are the same the migration will be done, otherwise the error will be generated. If destination qemu doesn't contain such bitmap it will be created.

2018-03-12trace: only permit standard C types and fixed size integer typesDaniel P. Berrangé
Some trace backends will compile code based on the declared trace events. It should not be assumed that the backends can resolve any QEMU specific typedefs. So trace events should restrict their argument types to the standard C types and fixed size integer types. Any complex pointer types can be declared as "void *" for purposes of trace events, since nothing will be dereferencing these pointer arguments. Signed-off-by: Daniel P.

2018-03-12simpletrace: fix timestamp argument typeStefan Hajnoczi
The timestamp argument to a trace event method is documented as follows: The method can also take a timestamp argument before the trace event arguments: def runstate_set(self, timestamp, new_state): ... Timestamps have the uint64_t type and are in nanoseconds. In reality methods with a timestamp argument actually receive a tuple like (123456789,) as the timestamp argument. This is due to a bug in simpletrace.py. This patch unpacks the tuple so that methods receive the correct timestamp argument type.

2018-03-12log-for-trace.h: Split out parts of log.h used by trace.hPeter Maydell
A persistent build problem we see is where a source file accidentally omits the #include of log.h. This slips through local developer testing because if you configure with the default (log) trace backend trace.h will pull in log.h for you. Compilation fails only if some other backend is selected. To make this error cause a compile failure regardless of the configured trace backend, split out the parts of log.h that trace.h requires into a new log-for-trace.h header. Since almost all manual uses of the log.h functions will use constants or functions which aren't in log-for-trace.h, this will let us catch missing #include "qemu/log.h" more consistently.

2018-03-12block: make BDRV_POLL_WHILE() re-entrancy safeStefan Hajnoczi
Nested BDRV_POLL_WHILE() calls can occur. Currently assert(!wait_->wakeup) fails in AIO_WAIT_WHILE() when this happens. This patch converts the bool wait_->need_kick flag to an unsigned wait_->num_waiters counter. Nesting works correctly because outer AIO_WAIT_WHILE() callers evaluate the condition again after the inner caller completes (invoking the inner caller counts as aio_poll() progress).

2018-03-12vga: fix region calculationGerd Hoffmann
Typically the scanline length and the line offset are identical. But in case they are not our calculation for region_end is incorrect. Using line_offset is fine for all scanlines, except the last one where we have to use the actual scanline length.

Add registry for audio drivers, using the existing audio_driver struct. Make all drivers register themself. The old list of audio_driver struct pointers is now a list of audio driver names, specifying the priority (aka probe order) in case no driver is explicitly asked for.

2018-03-12qapi: Add device ID and head parameters to screendumpThomas Huth
QEMU's screendump command can only take dumps from the primary display. When using multiple VGA cards, there is no way to get a dump from a secondary card or other display heads yet. So let's add a 'device' and a 'head' parameter to the HMP and QMP commands to be able to specify alternative devices and heads with the screendump command, too. Reviewed-by: Daniel P.

2018-03-12spice: add cursor_dmabuf supportGerd Hoffmann
Add support for cursor dmabufs. qemu has to render the cursor for that, so in case a cursor is present qemu allocates a new dmabuf, blits the scanout, blends in the pointer and passes on the new dmabuf to spice-server. Without cursor qemu continues to simply pass on the scanout dmabuf as-is.
