drm: Use idr_init_base(1) when using id==0 for invalid

2018-02-19T12:21:24Z

Use the new idr_init_base() function to create an IDR that knows id==0 is never allocated as it maps to an invalid identifier. By knowing that id==0 is invalid, the IDR can start from id=1 instead avoiding the issue of having to start each lookup from the zeroth leaf as id==0 is always unused (and thus the tree-of-bitmaps indicate that is the first available).

drm/syncobj: Stop reusing the same struct file for all syncobj -> fd

2017-12-22T04:14:39Z

The vk cts test: dEQP-VK.api.external.semaphore.opaque_fd.export_multiple_times_temporary triggers a lot of VFS: Close: file count is 0 Dave pointed out that clearing the syncobj->file from drm_syncobj_file_release() was sufficient to silence the test, but that opens a can of worm since we assumed that the syncobj->file was never unset. Stop trying to reuse the same struct file for every fd pointing to the drm_syncobj, and allocate one file for each fd instead. v2: Fixup return handling of drm_syncobj_fd_to_handle v2.1: [airlied: fix possible syncobj ref race] Reported-by: Dave Airlie Signed-off-by: Chris Wilson Tested-by: Dave Airlie Reviewed-by: Daniel Vetter Signed-off-by: Dave Airlie

drm/syncobj: Use proper methods for accessing rcu protected pointers

2017-11-09T18:34:21Z

Use rcu_dereference_protected() and rcu_assign_pointer() for accessing the rcu protected syncobj->fence pointer. This eliminates several sparse warnings.
