The main problem with this error handling was that it didn't clean up if i2c_add_numbered_adapter() failed. This code is pretty old, and doesn't match with today's checkpatch.pl standards so I took the opportunity to tidy it up a bit. I changed the NULL comparison, and removed the WARNING message if kzalloc() fails and updated the label names. Fixes: 1b082ccf ("gma500: Add Oaktrail support") Signed-off-by:

It seems like we can't have nice things, so let's just document the disappointing behaviour instead. The previous version assumed the kernel would perform the probing work when appropriate, however this is not the case today. Update the documentation to reflect reality. v2: - Improve commit message to explain why this change is made (Pekka) - Keep the bit about flickering (Daniel) - Explain when user-space should force-probe, and when it shouldn't (Daniel) Signed-off-by:

This an incremental refactor towards multiple dma-fence contexts in virtio-gpu. Since all fences are still allocated using &virtio_gpu_fence_driver.context, nothing should break and every processed fence will be signaled. The overall idea is every 3D context can allocate a number of dma-fence contexts. Each dma-fence context refers to it's own timeline. For example, consider the following case where virgl submits commands to the GPU (fence ids 1, 3) and does a metadata query with the CPU (fence id 5). In a different process, gfxstream submits commands to the GPU (fence ids 2, 4). fence_id (&dma_fence.seqno) | 1 2 3 4 5 ----------------------------------|----------- fence_ctx 0 (virgl gpu) | 1 3 fence_ctx 1 (virgl metadata query)| 5 fence_ctx 2 (gfxstream gpu) | 2 4 With multiple fence contexts, we can wait for the metadata query to finish without waiting for the virgl gpu to finish. virgl gpu does not have to wait for gfxstream gpu. The fence id still is the monotonically increasing sequence number, but it's only revelant to the specific dma-fence context. To fully enable this feature, we'll need to: - have each 3d context allocate a number of fence contexts. Not too hard with explicit context initialization on the horizon. - have guest userspace specify fence context when performing ioctls. - tag each fence emitted to the host with the fence context information. virtio_gpu_ctrl_hdr has padding + flags available, so that should be easy. This change goes in the direction specified above, by: - looking up the virtgpu_fence given a fence_id - signalling all prior fences in a given context - signalling current fence v2: fix grammar in comment v3: add r-b tags Reviewed-by:Anthoine Bourgeois <anthoine.bourgeois@gmail.com> Signed-off-by:

virtio_gpu_fence_event_process sets the last_fence_id and subsequently calls dma_fence_signal_locked(..). dma_fence_signal_locked(..) sets DMA_FENCE_FLAG_SIGNALED_BIT, which is actually checked before &dma_fence_ops.(*signaled) is called. The check for last_fence_id is therefore a bit redundant, and it will not be sufficient to check the last_fence_id for multiple synchronization timelines. Remove it. v3: add r-b tags Signed-off-by:

Purely conjecture, but I think the original locking inversion with the legacy page flip code between flipping and ttm's bo move function shoudn't exist anymore with atomic: With atomic the bo pinning and actual modeset commit is completely separated in the code patsh.

The new GEM object function drm_gem_cma_mmap() sets the VMA flags and offset as in the old implementation and immediately maps in the buffer's memory pages. Changing CMA helpers to use the GEM object function allows for the removal of the special implementations for mmap and gem_prime_mmap callbacks. The regular functions drm_gem_mmap() and drm_gem_prime_mmap() are now used. Signed-off-by:
