drm/virtio: drop owner assignment

virtio core already sets the .owner, so driver does not need to. Signed-off-by: Krzysztof Kozlowski Message-Id: <20240331-module-owner-virtio-v2-13-98f04bfaf46a@linaro.org> Signed-off-by: Michael S. Tsirkin

drm/virtio: Use fbdev-shmem

2024-05-02T09:33:21+00:00

Implement fbdev emulation with fbdev-shmem. Avoids the overhead of fbdev-generic's additional shadow buffering. No functional changes.

drm/virtio: Set segment size for virtio_gpu device

Set the segment size of the virtio_gpu device to the value used by the drm helpers when allocating sg lists to fix the following complaint from DMA_API debug code: DMA-API: virtio-pci 0000:07:00.0: mapping sg segment longer than device claims to support [len=262144] [max=65536] Cc: stable@vger.kernel.org Tested-by: Zhenyu Zhang Acked-by: Vivek Kasireddy Signed-off-by: Sebastian Ott Signed-off-by: Dmitry Osipenko Link: https://patchwork.freedesktop.org/patch/msgid/7258a4cc-da16-5c34-a042-2a23ee396d56@redhat.com

drm: Disable the cursor plane on atomic contexts with virtualized drivers

2023-11-24T10:57:54+00:00

Cursor planes on virtualized drivers have special meaning and require that the clients handle them in specific ways, e.g. the cursor plane should react to the mouse movement the way a mouse cursor would be expected to and the client is required to set hotspot properties on it in order for the mouse events to be routed correctly. This breaks the contract as specified by the "universal planes". Fix it by disabling the cursor planes on virtualized drivers while adding a foundation on top of which it's possible to special case mouse cursor planes for clients that want it. Disabling the cursor planes makes some kms compositors which were broken, e.g. Weston, fallback to software cursor which works fine or at least better than currently while having no effect on others, e.g. gnome-shell or kwin, which put virtualized drivers on a deny-list when running in atomic context to make them fallback to legacy kms and avoid this issue.

drm/virtio: Use pci_is_vga() to identify VGA devices

2023-10-06T22:19:01+00:00

Use pci_is_vga() to identify VGA devices instead of open-coding the class test. This means virtio_gpu_pci_quirk() will apply to old PCI_CLASS_NOT_DEFINED_VGA (0x0001) devices as well as the PCI_CLASS_DISPLAY_VGA (0x0300) devices it did previously.

drm/virtio: Add option to disable KMS support

2023-03-03T20:29:54+00:00

Add a build option to disable modesetting support. This is useful in cases where the guest only needs to use the GPU in a headless mode, or (such as in the CrOS usage) window surfaces are proxied to a host compositor. As the modesetting ioctls are a big surface area for potential security bugs to be found (it's happened in the past, we should assume it will again in the future), it makes sense to have a build option to disable those ioctls in cases where they serve no legitimate purpose. v2: Use more if (IS_ENABLED(...)) v3: Also permit the host to advertise no scanouts v4: Spiff out commit msg v5: Make num_scanouts==0 and DRM_VIRTIO_GPU_KMS=n behave the same v6: Drop conditionally building virtgpu_display.c and early-out of it's init/fini fxns instead Signed-off-by: Rob Clark Reviewed-by: Dmitry Osipenko Reviewed-by: Javier Martinez Canillas Reviewed-by: Gerd Hoffmann Signed-off-by: Dmitry Osipenko Link: https://patchwork.freedesktop.org/patch/msgid/20230302233506.3146290-1-robdclark@gmail.com
