virtio-gpu: fix ioctl and expose the fixed status to userspace.

2018-05-30T05:50:32+00:00

[ Upstream commit 9a191b114906457c4b2494c474f58ae4142d4e67 ] This exposes to mesa that it can use the fixed ioctl for querying later cap sets, cap set 1 is forever frozen in time.

drm/virtio: fix vq wait_event condition

2018-05-01T22:13:05+00:00

commit d02d270014f70dcab0117776b81a37b6fca745ae upstream. Wait until we have enough space in the virt queue to actually queue up our request. Avoids the guest spinning in case we have a non-zero amount of free entries but not enough for the request.

drm/virtio: fix framebuffer sparse warning

2017-08-11T15:49:35+00:00

[ Upstream commit 71d3f6ef7f5af38dea2975ec5715c88bae92e92d ] virtio uses normal ram as backing storage for the framebuffer, so we should assign the address to new screen_buffer (added by commit 17a7b0b4d9749f80d365d7baff5dec2f54b0e992) instead of screen_base.

virtio-gpu: fix vblank events

2016-11-03T00:14:19+00:00

virtio-gpu sends vblank events in virtio_gpu_crtc_atomic_flush, and because of that it must be called for disabled planes too. Ask drm_atomic_helper_commit_planes to do that. v2: update to use new drm_atomic_helper_commit_planes() API. Signed-off-by: Gerd Hoffmann Signed-off-by: Gustavo Padovan Signed-off-by: Dave Airlie

drm: virtio: reinstate drm_virtio_set_busid()

2016-10-04T03:10:30+00:00

Before commit a325725633c2 ("drm: Lobotomize set_busid nonsense for !pci drivers"), several DRM drivers for platform devices used to expose an explicit "drm_driver.set_busid" callback, invariably backed by drm_platform_set_busid(). Commit a325725633c2 removed drm_platform_set_busid(), along with the referring .set_busid field initializations. This was justified because interchangeable functionality had been implemented in drm_dev_alloc() / drm_dev_init(), which DRM_IOCTL_SET_VERSION would rely on going forward. However, commit a325725633c2 also removed drm_virtio_set_busid(), for which the same consolidation was not appropriate: this .set_busid callback had been implemented with drm_pci_set_busid(), and not drm_platform_set_busid(). The error regressed Xorg/xserver on QEMU's "virtio-vga" card; the drmGetBusid() function from libdrm would no longer return stable PCI identifiers like "pci:0000:00:02.0", but rather unstable platform ones like "virtio0".

drm: Don't swallow error codes in drm_dev_alloc()

2016-09-22T11:03:48+00:00

There are many reasons other than ENOMEM that drm_dev_init() can fail. Return ERR_PTR rather than NULL to be able to distinguish these in the caller. Signed-off-by: Tom Gundersen Signed-off-by: Sean Paul Link: http://patchwork.freedesktop.org/patch/msgid/20160921145919.13754-2-teg@jklm.no
