* virtio-gpu: fix crashes upon warm reboot with vga modeMarc-André Lureau2018-08-071-0/+1
| | | | | | | | | | | | | | | | | | | | | 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. https://bugs.launchpad.net/qemu/+bug/1784900/ Reported-by: Stefan Berger <stefanb@linux.vnet.ibm.com> Signed-off-by: Marc-André Lureau <marcandre.lureau@redhat.com> Reviewed-by: Michael S.

* virtio-gpu-3d: Drop workaround for VIRTIO_GPU_CAPSET_VIRGL2 definePeter Maydell2018-06-261-5/+0
| | | | | | | | | | | | In commit a8bff79e9f27df we added a definition to hw/virtio/virtio-gpu.h for VIRTIO_GPU_CAPSET_VIRGL2, as a workaround for it not yet being in the Linux kernel headers. In commit 77d361b13c19 we updated our kernel headers to a version which does define the macro, so we can now remove our workaround.

* virtio-gpu-3d: Define VIRTIO_GPU_CAPSET_VIRGL2 elsewhereAlex Williamson2018-06-011-0/+6
| | | | | | | | | | | | | | | | | | Commit 5643cc94ac1c ("virtio-gpu-3d: add support for second capability set (v4)") updated virtio_gpu.h with a define that does not yet(?) exist upstream resulting in build breakage every time Linux headers are updated via the standard update script. Conditionally define this within QEMU code instead to avoid future breakage.

| | | | | | | | | | | | | | | Due to a kernel bug we can never increase the size of capability set 1, so introduce a new capability set in parallel, old userspace will continue to use the old set, new userspace will start using the new one when it detects a fixed kernel. v2: don't use a define from virglrenderer, just probe it. v3: fix compilation when virglrenderer disabled v4: fix style warning, just use ?: op instead.

* virtio-gpu: track and limit host memory allocationsGerd Hoffmann2016-12-201-0/+3
| | | | | | | | | | | | | | | | | | | 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.

* virtio-gpu: fix missing log.h include fileDaniel P. Berrange2016-08-161-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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: In file included from /home/berrange/src/virt/qemu/hw/display/virtio-gpu-3d.c:19:0: /home/berrange/src/virt/qemu/hw/display/virtio-gpu-3d.c: In function ‘virgl_cmd_create_resource_2d’: /home/berrange/src/virt/qemu/include/hw/virtio/virtio-gpu.h:138:13: error: implicit declaration of function ‘qemu_log_mask’ [-Werror=implicit-function-declaration] qemu_log_mask(LOG_GUEST_ERROR, \ ^ /home/berrange/src/virt/qemu/hw/display/virtio-gpu-3d.c:34:5: note: in expansion of macro ‘VIRTIO_GPU_FILL_CMD’ VIRTIO_GPU_FILL_CMD(c2d); ^~~~~~~~~~~~~~~~~~~ /home/berrange/src/virt/qemu/hw/display/virtio-gpu-3d.c:34:5: error: nested extern declaration of ‘qemu_log_mask’ [-Werror=nested-externs] In file included from /home/berrange/src/virt/qemu/hw/display/virtio-gpu-3d.c:19:0: /home/berrange/src/virt/qemu/include/hw/virtio/virtio-gpu.h:138:27: error: ‘LOG_GUEST_ERROR’ undeclared (first use in this function) qemu_log_mask(LOG_GUEST_ERROR, \ [snip many more errors] Signed-off-by: Daniel P.
