Extend the uAPI with a new job requirement flag for cycle counters. This requirement is used by userland to indicate that a job requires cycle counters or system timestamp to be propagated. (for use with write value timestamp jobs) We cannot enable cycle counters unconditionally as this would result in an increase of GPU power consumption. As a result, they should be left off unless required by the application. If a job requires cycle counters or system timestamps propagation, we must enable cycle counting before issuing a job and disable it right after the job completes. Since this extends the uAPI and because userland needs a way to advertise features like VK_KHR_shader_clock conditionally, we bumps the driver minor version. v2: - Rework commit message - Squash uAPI changes and implementation in this commit - Simplify changes based on Steven Price comments v3: - Add Steven Price r-b - Fix a codestyle issue Signed-off-by: Mary Guillemard <mary.guillemard@collabora.com> Reviewed-by: Steven Price <steven.price@arm.com> Tested-by: Heiko Stuebner <heiko@sntech.de> Signed-off-by: Steven Price <steven.price@arm.com> Link: https://patchwork.freedesktop.org/patch/msgid/20240819080224.24914-3-mary.guillemard@collabora.com |
