From: Kan Liang Date: Tue, 20 May 2025 18:16:41 +0000 (-0700) Subject: loongarch/perf: Remove driver-specific throttle support X-Git-Tag: v6.16-rc1~196^2~6 X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=b82f8885d1fd46d88c554877a0d87e9a1c3d7165;p=thirdparty%2Fkernel%2Flinux.git loongarch/perf: Remove driver-specific throttle support The throttle support has been added in the generic code. Remove the driver-specific throttle support. Besides the throttle, perf_event_overflow may return true because of event_limit. It already does an inatomic event disable. The pmu->stop is not required either.
