Sampler TS is an hardware optimization that can be used when rendering to textures. After rendering to a resource with TS enabled, the texture unit can use this to bypass lookups to empty tiles. This also means a resolve-in-place can be avoided to flush the TS.
This patch series adds support for sampler TS on hardware that supports this. It also contains an optimization when not using sampler TS, as resolve-in-place will now be skipped if a resource has no (valid) TS. For example the 'shadow' test in glmark2 increases in performance with: before: [shadow] <default>: FPS: 130 FrameTime: 7.692 ms after: [shadow] <default>: FPS: 244 FrameTime: 4.098 ms Wladimir J. van der Laan (3): etnaviv: rnndb update etnaviv: Add TS_SAMPLER formats to etnaviv_format etnaviv: Add sampler TS support src/gallium/drivers/etnaviv/etnaviv_emit.c | 26 +++++++ src/gallium/drivers/etnaviv/etnaviv_format.c | 19 +++++ src/gallium/drivers/etnaviv/etnaviv_format.h | 3 + src/gallium/drivers/etnaviv/etnaviv_texture.c | 92 +++++++++++++++++++++++-- src/gallium/drivers/etnaviv/etnaviv_texture.h | 5 ++ src/gallium/drivers/etnaviv/hw/common.xml.h | 2 +- src/gallium/drivers/etnaviv/hw/common_3d.xml.h | 2 +- src/gallium/drivers/etnaviv/hw/state.xml.h | 4 +- src/gallium/drivers/etnaviv/hw/state_3d.xml.h | 14 +++- src/gallium/drivers/etnaviv/hw/state_blt.xml.h | 4 +- src/gallium/drivers/etnaviv/hw/texdesc_3d.xml.h | 3 +- 11 files changed, 158 insertions(+), 16 deletions(-) -- 2.7.4 _______________________________________________ mesa-dev mailing list [email protected] https://lists.freedesktop.org/mailman/listinfo/mesa-dev
