Subject: [PATCH 10/11] perf/x86/intel: Update event constraints and cache_extra_regs[] for SRF
Date: Fri, 15 May 2026 14:11:42 +0800 [thread overview]
Message-ID: <20260515061143.338553-11-dapeng1.mi@linux.intel.com> (raw)
In-Reply-To: <20260515061143.338553-1-dapeng1.mi@linux.intel.com>
Update perf hard-coded event constraints and cache_extra_regs[] for
Sierra Forest according to the latest SRF perfmon events (V1.17).
SRF has same uarch (crestmont) as MTL E-core and shares same perf
events, so directly apply the crestmont perf events.
SRF perfmon events:
