Display refreshment is invoked by a timer and it erroneously disables the active scanout if it happens to be invoked after scanout has been enabled. This offending scanout-disable race condition with a timer can be easily hit when Qemu runs with a disabled vsync by using SDL or GTK displays (with vblank_mode=0 for GTK). Refreshment of display's content shouldn't disable the active display. Fix it by keeping the scanout's state unchanged when display is redrawn.

Add support for DRM native contexts to VirtIO-GPU. DRM context is enabled using a new virtio-gpu-gl device option "drm=true". Unlike Virgl and Venus contexts that operate on application API level, DRM native contexts work on a kernel UAPI level. This lower level results in a lightweight context implementations that yield better performance. Signed-off-by: -

Support asynchronous fencing feature of virglrenderer. It allows Qemu to handle fence as soon as it's signalled instead of periodically polling the fence status. This feature is required for enabling DRM context support in Qemu because legacy fencing mode isn't supported for DRM contexts in virglrenderer. Signed-off-by: -

If EGL is used, we can rely on dmabuf to import textures without doing copies. To get this working on X11, we use the existing SDL hint: SDL_HINT_VIDEO_X11_FORCE_EGL (because dmabuf can't be used with GLX). Signed-off-by:

SDL API changes GL context to a newly created GL context, which differs from other GL providers that don't switch context. Change SDL backend to restore the original GL context. This allows Qemu's virtio-gpu to support new virglrenderer async-fencing feature for Virgl context, otherwise it's impossible for virglrenderer to switch GL context from a thread that waits for async-fences.

virtio_gpu_virgl_get_num_capsets will return "num_capsets", but we can't assume that capset_index 1 is always VIRGL2 once we'll support more capsets, like Venus and DRM capsets. Register capsets dynamically to avoid that problem. Reviewed-by:

The udmabuf usage is mandatory when virgl is disabled and blobs feature enabled in the Qemu machine configuration. If virgl and blobs are enabled, then udmabuf requirement is optional. Since udmabuf isn't widely supported by a popular Linux distros today, let's relax the udmabuf requirement for blobs=on,virgl=on. Now, a full-featured virtio-gpu acceleration is available to Qemu users without a need to have udmabuf available in the system. Reviewed-by:

Accessing another device in a post_load hook is a bad idea, because the order of device save/restore is not fixed, and so this cross-device access makes the save/restore non-deterministic. We previously only flagged up this requirement in the record-and-replay developer docs; repeat it in the main migration documentation, where a developer trying to implement a post_load hook is more likely to see it.

hw/char/serial currently contains the implementation of both TYPE_SERIAL and TYPE_SERIAL_MM. According to serial_class_init(), TYPE_SERIAL is an internal class while TYPE_SERIAL_MM is used by numerous machine types directly. Let's move the latter into its own module which makes the dependencies more obvious and the code more tidy. The includes and the dependencies have been converted mechanically except in the hw/char directories which were updated manually. The result was compile-tested. Now, only hw/char makes direct use of TYPE_SERIAL: # grep -r -e "select SERIAL" | grep -v SERIAL_ hw/char/Kconfig: select SERIAL hw/char/Kconfig: select SERIAL hw/char/Kconfig: select SERIAL hw/char/Kconfig: select SERIAL hw/char/Kconfig: select SERIAL # grep -r -e "/serial\\.h" include/hw/char/serial-mm.h:#include "hw/char/serial.h" hw/char/serial-pci-multi.c:#include "hw/char/serial.h" hw/char/serial.c:#include "hw/char/serial.h" hw/char/serial-isa.c:#include "hw/char/serial.h" hw/char/serial-pci.c:#include "hw/char/serial.h" Tested-by:
