Christian König d67b5a2b97 dma-buf: add dma_fence_timestamp helper ... commit b83ce9cb4a465b8f9a3fa45561b721a9551f60e3 upstream. When a fence signals there is a very small race window where the timestamp isn't updated yet. sync_file solves this by busy waiting for the timestamp to appear, but on other ocassions didn't handled this correctly. Provide a dma_fence_timestamp() helper function for this and use it in all appropriate cases. Another alternative would be to grab the spinlock when that happens. v2 by teddy: add a wait parameter to wait for the timestamp to show up, in case the accurate timestamp is needed and/or the timestamp is not based on ktime (e.g. hw timestamp) v3 chk: drop the parameter again for unified handling Signed-off-by: Yunxiang Li <Yunxiang.Li@amd.com> Signed-off-by: Christian König <christian.koenig@amd.com> Fixes: 1774baa64f ("drm/scheduler: Change scheduled fence track v2") Reviewed-by: Alex Deucher <alexander.deucher@amd.com> CC: stable@vger.kernel.org Link: https://patchwork.freedesktop.org/patch/msgid/20230929104725.2358-1-christian.koenig@amd.com Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>		2023-10-19 23:08:57 +02:00
