2018-03-16target/xtensa: add linux-user supportMax Filippov22-44/+1705
Import list of syscalls from the kernel source. Conditionalize code/data that is only used with softmmu. Implement exception handlers. Implement signal hander (only the core registers for now, no coprocessors or TIE).

2018-03-13linux-user: fix target_mprotect/target_munmap error return valuesMax Filippov1-4/+4
target_mprotect/target_munmap return value goes through get_errno at the call site, thus the functions must either set errno to host error code and return -1 or return negative guest error code. Do the latter.

2018-03-13linux-user: fix assertion in shmdtMax Filippov1-1/+7
shmdt fails to call mmap_lock/mmap_unlock around page_set_flags, resulting in the following assertion: page_set_flags: Assertion `have_mmap_lock()' failed. Wrap shmdt internals into mmap_lock/mmap_unlock.

2018-03-13linux-user: fix mmap/munmap/mprotect/mremap/shmatMax Filippov4-16/+31
In linux-user QEMU that runs for a target with TARGET_ABI_BITS bigger than L1_MAP_ADDR_SPACE_BITS an assertion in page_set_flags fires when mmap, munmap, mprotect, mremap or shmat is called for an address outside the guest address space. mmap and mprotect should return ENOMEM in such case. Change definition of GUEST_ADDR_MAX to always be the last valid guest address. Account for this change in open_self_maps. Add macro guest_addr_valid that verifies if the guest address is valid. Add function guest_range_valid that verifies if address range is within guest address space and does not wrap around. Use that macro in mmap/munmap/mprotect/mremap/shmat for error checking.

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 Maydell3-21/+45
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 Hajnoczi2-32/+31
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).

2018-03-12audio: add driver registryGerd Hoffmann12-45/+106
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 Huth4-10/+35
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 Hoffmann3-5/+121
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.

2018-03-12vnc: deal with surface NULL pointersGerd Hoffmann3-4/+18
Secondary displays in multihead setups are allowed to have a NULL DisplaySurface. Typically user interfaces handle this by hiding the window which shows the display in question. This isn't an option for vnc though because it simply hasn't a concept of windows or outputs. So handle the situation by showing a placeholder DisplaySurface instead. Also check in console_select whenever a surface is preset in the first place before requesting an update. This fixes a segfault which can be triggered by switching to an unused display (via vtrl-alt-<nr>) in a multihead setup, for example using -device virtio-vga,max_outputs=2.
