[PATCH v2 0/5] *** Delay context create cmd ***
by Gurchetan Singh 15 Feb '20

15 Feb '20

Let's delay enqueuing the context creation command until the first 3D ioctl, as we add more context types. This series is based on kraxel's "[PATCH v3 0/4] drm/virtio: rework batching" patches. Gurchetan Singh (5): drm/virtio: use consistent names for drm_files drm/virtio: factor out context create hyercall drm/virtio: track whether or not a context has been initiated drm/virtio: enqueue virtio_gpu_create_context after the first 3D ioctl drm/virtio: add virtio_gpu_context_type drivers/gpu/drm/virtio/virtgpu_drv.h | 1 + drivers/gpu/drm/virtio/virtgpu_ioctl.c | 55 +++++++++++++++++++++----- drivers/gpu/drm/virtio/virtgpu_kms.c | 25 +++--------- 3 files changed, 52 insertions(+), 29 deletions(-) -- 2.25.0.265.gbab2e86ba0-goog

[PATCH v2 0/5] drm/nouveau: DP interlace fixes
by Lyude Paul 14 Feb '20

14 Feb '20

Currently, nouveau doesn't actually bother to try probing whether or not it can actually handle interlaced modes over DisplayPort. As a result, on volta and later we'll end up trying to set an interlaced mode even when it's not supported and cause the front end for the display engine to hang. So, let's teach nouveau to reject interlaced modes on hardware that can't actually handle it. Additionally for MST, since we accomplish this by simply reusing more of the SST mode validation we also get (some) basic bw validation for modes we detect on MST connectors completely for free.

[git pull] drm fixes for 5.6-rc2
by Dave Airlie 14 Feb '20

14 Feb '20

Hey Linus, This week's fixes ready for rc2. The core has a build fix for edid code on certain compilers/arches/, one MST fix and one vgem fix. Regular amdgpu fixes, and a couple of small driver fixes. The i915 fixes are bit larger than normal for this stage, but they were having CI issues last week, and they hadn't sent any fixes last week due to this. Regards, Dave. drm-fixes-2020-02-14: drm fixes for 5.6-rc2 core: - edid build fix mst: - fix NULL ptr deref vgem: - fix close after free msm: - better dma-api usage sun4i: - disable allow_fb_modifiers amdgpu: -
