Description
Mesa performance in SynMark2 v7 CSDof test dropped 3-7% on all our GEN9 devices.
Setup:
- Ubuntu 18.04
- Unity / compiz desktop
- Mesa from git
- X server and drm-tip kernel from git within last 1-2 months, with modifier support enabled
- FullHD monitor
Test-case:
- synmark2 OglCSDof (configured to run in fullscreen FullHD resolution.)
Regression happened between following commits:
- 2019-05-14 16:23:12 e8139286: iris/resource: Drop redundant checks for aux support
- 2019-05-15 04:34:49 a9cef4f0: gallium: Add default check for PIPE_CAP_FRAGMENT_SHADER_INTERLOCK
Notes:
- There are a lot of compiler changes between these dates
- Only CSDof test performance changed, and only on GEN9 devices (not on GEN7-8 ones)
Version: git
