Author: Mike Blumenkrantz <michael.blumenkra...@gmail.com> Date: Mon Jan 8 09:51:31 2024 -0500 zink: always force flushes when originating from api frontend flags=0 is used for e.g., glFenceSync, which apps use to insert sync points to determine when all prior work has completed. eliding these flushes into no-ops is fine for all scenarios except when the last op was a present, in which case the no-op (previous) fence will not sync as expected for the present and graphical artifacts will result in the future, this may be changed back to the previous behavior if/when presentation gains timeline semaphore capabilities by providing the last timeline id as a fence instead of the last batch fixes #10386 cc: mesa-stable Part-of: <https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/26935> (cherry picked from commit 03f049f49730b8b1268f2975fc34ac2b1f9a4ef9) --- .pick_status.json | 2 +- src/gallium/drivers/zink/zink_context.c | 3 ++- 2 files changed, 3 insertions(+), 2 deletions(-) diff --git a/.pick_status.json b/.pick_status.json index 9a8f56ce3b3..40f3634c46d 100644 --- a/.pick_status.json +++ b/.pick_status.json @@ -3294,7 +3294,7 @@ "description": "zink: always force flushes when originating from api frontend", "nominated": true, "nomination_type": 0, - "resolution": 0, + "resolution": 1, "main_sha": null, "because_sha": null, "notes": null diff --git a/src/gallium/drivers/zink/zink_context.c b/src/gallium/drivers/zink/zink_context.c index f4716527883..28afec232eb 100644 --- a/src/gallium/drivers/zink/zink_context.c +++ b/src/gallium/drivers/zink/zink_context.c @@ -3849,7 +3849,8 @@ zink_flush(struct pipe_context *pctx, } } - if (!batch->has_work) { + /* TODO: if swapchains gain timeline semaphore semantics, `flags` can be eliminated and no-op fence can return timeline id */ + if (!batch->has_work && flags) { if (pfence) { /* reuse last fence */ fence = ctx->last_fence;
