Merge v6.3-rc4 into drm-next

2023-03-29T14:00:23+00:00

I just landed the fence deadline PR from Rob that a bunch of drivers want/need to apply driver-specific patches. Backmerge -rc4 so that they don't have to be stuck on -rc2 for no reason at all. Signed-off-by: Daniel Vetter

drm/virtio: use strscpy() to instead of strncpy()

The implementation of strscpy() is more robust and safer. That's now the recommended way to copy NUL terminated strings. Signed-off-by: Xu Panda Signed-off-by: Yang Yang Signed-off-by: Dmitry Osipenko Link: https://patchwork.freedesktop.org/patch/msgid/202212070913161959936@zte.com.cn

drm/virtio: Pass correct device to dma_sync_sgtable_for_device()

2023-02-26T23:39:24+00:00

The "vdev->dev.parent" should be used instead of "vdev->dev" as a device for which to perform the DMA operation in both virtio_gpu_cmd_transfer_to_host_2d(3d). Because the virtio-gpu device "vdev->dev" doesn't really have DMA OPS assigned to it, but parent (virtio-pci or virtio-mmio) device "vdev->dev.parent" has. The more, the sgtable in question the code is trying to sync here was mapped for the parent device (by using its DMA OPS) previously at: virtio_gpu_object_shmem_init()->drm_gem_shmem_get_pages_sgt()-> dma_map_sgtable(), so should be synced here for the same parent device.

drm/virtio: Return proper error codes instead of -1

2022-07-19T12:40:58+00:00

Don't return -1 in error cases, return proper error code. The returned error codes propagate to error messages and to userspace and it's always good to have a meaningful error number for debugging purposes.

drm/virtio: Improve DMA API usage for shmem BOs

2022-07-19T12:40:58+00:00

DRM API requires the DRM's driver to be backed with the device that can be used for generic DMA operations. The VirtIO-GPU device can't perform DMA operations if it uses PCI transport because PCI device driver creates a virtual VirtIO-GPU device that isn't associated with the PCI. Use PCI's GPU device for the DRM's device instead of the VirtIO-GPU device and drop DMA-related hacks from the VirtIO-GPU driver.

drm/virtio: Check whether transferred 2D BO is shmem

Transferred 2D BO always must be a shmem BO. Add check for that to prevent NULL dereference if userspace passes a VRAM BO.

drm: Drop drm_edid.h from drm_crtc.h

2022-06-20T20:53:55+00:00

drm_crtc.h has no need for drm_edid.h, so don't include it. Avoids useless rebuilds of the entire universe when touching drm_edid.h. Quite a few placs do currently depend on drm_edid.h without actually including it directly.
