From: Ian Rogers Date: Thu, 24 Aug 2023 18:32:12 +0000 (-0700) Subject: perf jevents: Don't append Unit to desc X-Git-Tag: v6.6.17~3940^2~32 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=eeb6b12992c4a348af6773e50084f981dc3dda76;p=platform%2Fkernel%2Flinux-rpi.git perf jevents: Don't append Unit to desc Unit with the PMU name is appended to desc in jevents.py, but on hybrid platforms it causes the desc to differ from the regular non-hybrid system with a PMU of 'cpu'. Having differing descs means the events don't deduplicate. To make the perf list output not differ, append the Unit on again in the perf list printing code. On x86 reduces the binary size by 409,600 bytes or about 4%. Update pmu-events test expectations to match the differently generated pmu-events.c code.
