Priority: medium Bug ID: 82050 Assignee: dri-devel@lists.freedesktop.org Summary: R9270X pyrit benchmark perf regressions with latest kernel/llvm Severity: normal Classification: Unclassified OS: All Reporter: adf.lists@gmail.com Hardware: Other Status: NEW Version: git Component: Drivers/Gallium/radeonsi Product: Mesa
Don't really have time to bisect this but posting FYI.
Maybe pyrit benchmark is the glxgears of benchmarks - if so please say so and I'll ignore it :-)
Status Que for my R9 270X pyrit 0.3.0 since I got it in May has been around -
Computed 75761.96 PMKs/s total. #1: 'OpenCL-Device 'AMD PITCAIRN'': 73256.9 PMKs/s (RTT 0.8) #2: 'CPU-Core (SSE2)': 743.3 PMKs/s (RTT 2.9) #3: 'CPU-Core (SSE2)': 741.3 PMKs/s (RTT 2.8) #4: 'CPU-Core (SSE2)': 740.2 PMKs/s (RTT 2.9) #5: 'Network-Clients': 0.0 PMKs/s (RTT 0.0)
This was kernel agd5f drm-fixes-3.16-wip
I noticed yesterday after trying agd5f drm-next-3.17-rebased-on-fixes that I lost around 10,000 PMKs/s with the newer kernel.
Both were with yesterdays mesa but llvm was older say a couple of weeks.
Updated llvm and mesa today and it's regressed more on both kernels -
drm-fixes-3.16-wip
