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: Add a signal ioctl (v3)

2017-08-29T00:16:25Z

This IOCTL provides a mechanism for userspace to trigger a sync object directly. There are other ways that userspace can trigger a syncobj such as submitting a dummy batch somewhere or hanging on to a triggered sync_file and doing an import. This just provides an easy way to manually trigger the sync object without weird hacks. The motivation for this IOCTL is Vulkan fences. Vulkan lets you create a fence already in the signaled state so that you can wait on it immediatly without stalling. We could also handle this with a new create flag to ask the driver to create a syncobj that is already signaled but the IOCTL seemed a bit cleaner and more generic. v2: - Take an array of sync objects (Dave Airlie) v3: - Throw -EINVAL if pad != 0 Signed-off-by: Jason Ekstrand Signed-off-by: Dave Airlie

drm/syncobj: Add a reset ioctl (v3)

2017-08-29T00:16:19Z

This just resets the dma_fence to NULL so it looks like it's never been signaled. This will be useful once we add the new wait API for allowing wait on "submit and signal" behavior. v2: - Take an array of sync objects (Dave Airlie) v3: - Throw -EINVAL if pad != 0 Signed-off-by: Jason Ekstrand Reviewed-by: Christian König (v1) Signed-off-by: Dave Airlie
