Gerd Hoffmann 9032e3d71c virtio-gpu: delay virglrenderer reset when blocked.
If renderer_blocked is set do not call virtio_gpu_virgl_reset().
Instead set a flag indicating that virglrenderer needs a reset.
When renderer_blocked gets cleared do the actual reset call.

Without this we can trigger an assert in spice due to calling
spice_qxl_gl_scanout() while another operation is still running:

spice_qxl_gl_scanout: condition `qxl_state->gl_draw_cookie == GL_DRAW_COOKIE_INVALID' failed

Marc-André Lureau 93f874fe9d virtio-gpu: fix crashes upon warm reboot with vga mode
With vga=775 on the Linux command line a first boot of the VM running
Linux works fine. After a warm reboot it crashes during Linux boot.

Before that, valgrind points out bad memory write to console
surface. The VGA code is not aware that virtio-gpu got a message
surface scanout when the display is disabled. Let's reset VGA graphic
mode when it is the case, so that a new display surface is created
when doing further VGA operations.

kernel headers to a version which does define the macro, so we can
now remove our workaround.

Gerd Hoffmann 9b7621bca2 virtio-gpu: track and limit host memory allocations
This patch makes virtio-gpu track host memory allocations for ressources
and applies a limit (configurable 256M by default).  When exceeding the
limit virtio-gpu throws VIRTIO_GPU_RESP_ERR_OUT_OF_MEMORY errors (like
it already does today when pixman image allocations fail).

This patch covers 2d mode only.  For 3d mode we have to figure how we
are going to handle this best.  qemu doesn't track resources in case
virglrenderer is used, so I guess we should extend virglrenderer to
allow setting a limit, then let qemu set the limit and catch
virgl_renderer_resource_create failures.

Daniel P. Berrange 8afc224ffe virtio-gpu: fix missing log.h include file
The virtio-gpu.h file defines a macro VIRTIO_GPU_FILL_CMD
which includes a call to qemu_log_mask, but does not
include qemu/log.h. In a default configure, it is lucky
and gets qemu/log.h indirectly due to the 'log' trace
backend being enabled. If that trace backend is disabled
though, eg

 ./configure --enable-trace-backends=nop

Then the build will fail:
