Christian König	f781f661e8	dma-buf: keep the signaling time of merged fences v3 ... Some Android CTS is testing if the signaling time keeps consistent during merges. v2: use the current time if the fence is still in the signaling path and the timestamp not yet available. v3: improve comment, fix one more case to use the correct timestamp Signed-off-by: Christian König <christian.koenig@amd.com> Reviewed-by: Luben Tuikov <luben.tuikov@amd.com> Link: https://patchwork.freedesktop.org/patch/msgid/20230630120041.109216-1-christian.koenig@amd.com	2023-07-03 13:47:06 +02:00
Christian König	4fa05a67b5	dma-buf: revert "return only unsignaled fences in dma_fence_unwrap_for_each v3" ... This reverts commit 8f61973718485f3e89bc4f408f929048b7b47c83. It turned out that this is not correct. Especially the sync_file info IOCTL needs to see even signaled fences to correctly report back their status to userspace. Instead add the filter in the merge function again where it makes sense.

Christian König	245a4a7b53	dma-buf: generalize dma_fence unwrap & merging v3 ... Introduce a dma_fence_unwrap_merge() macro which allows to unwrap fences which potentially can be containers as well and then merge them back together into a flat dma_fence_array. v2: rename the function, add some more comments about how the wrapper is used, move filtering of signaled fences into the unwrap iterator, add complex selftest which covers more cases. v3: fix signaled fence filtering once more Signed-off-by: Christian König <christian.koenig@amd.com> Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch> Link: https://patchwork.freedesktop.org/patch/msgid/20220518135844.3338-5-christian.koenig@amd.com	2022-05-30 14:24:04 +02:00
