Hibernate bricks the machine if a discrete GPU was disabled via echo IGD > /sys/kernel/debug/vgaswitcheroo/switch The freeze and thaw handler lacks checking the GPU power state, as suspend and resume do. This patch add the checks and fix this issue. Signed-off-by:

Add amdxdna_gem_prime_export() and amdxdna_gem_prime_import() for BO import and export. Register mmu notifier for imported BO as well. When MMU_NOTIFIER_UNMAP event is received, queue work to remove the notifier. The same BO could be mapped multiple times if it is exported and imported by an application. Use a link list to track VMAs the BO been mapped. v2: Rebased and call get_dma_buf() before dma_buf_attach() v3: Removed import_attach usage Reviewed-by:

Since the context-type additions to the virtio-gpu spec, these have been defined locally in guest user-space, and virtio-gpu backend library code. Now, these capsets have been stabilized, and should be defined in a common space, in both the virtio_gpu header, and alongside the virtgpu_drm interface that they apply to. Reviewed-by:

The vmapped pages shall be pinned in memory and previously get/put_pages() were implicitly hard-pinning/unpinning the pages. This will no longer be the case with addition of memory shrinker because pages_use_count > 0 won't determine anymore whether pages are hard-pinned (they will be soft-pinned), while the new pages_pin_count will do the hard-pinning. Switch the vmap/vunmap() to use pin/unpin() functions in a preparation of addition of the memory shrinker support to drm-shmem. Acked-by:

With the addition of memory shrinker support to drm-shmem, the pages_use_count will no longer determine whether pages are hard-pinned in memory, but whether pages exist and are soft-pinned (and could be swapped out).

Everything that uses the mapped buffer should be agnostic to is_iomem. The only reason for the is_iomem test is that we're setting shmem->vaddr to the returned map->vaddr. Now that the shmem->vaddr code is gone, remove the obsoleted is_iomem test to clean up the code. Acked-by:

drm_dp_dpcd_read_link_status() follows the "return error code or number of bytes read" protocol, with the code returning less bytes than requested in case of some errors. However most of the drivers interpreted that as "return error code in case of any error". Switch drm_dp_dpcd_read_link_status() to drm_dp_dpcd_read_data() and make it follow that protocol too.

Existing DPCD access functions return an error code or the number of bytes being read / write in case of partial access. However a lot of drivers either (incorrectly) ignore partial access or mishandle error codes. In other cases this results in a boilerplate code which compares returned value with the size. Implement new set of DPCD access helpers, which ignore partial access, always return 0 or an error code. Suggested-by:
