From b216af2eb4618caec6bef32d5886a9700b0ecfeb Mon Sep 17 00:00:00 2001 From: Kan Liang Date: Tue, 20 May 2025 11:16:44 -0700 Subject: [PATCH] mips/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.
