Subject: [Patch v9 03/24] perf/x86/intel: Enable large PEBS sampling for XMMs
Date: Mon,  6 Jul 2026 09:54:18 +0800	[thread overview]
Message-ID: <20260706015439.3040804-4-dapeng1.mi@linux.intel.com> (raw)
In-Reply-To: <20260706015439.3040804-1-dapeng1.mi@linux.intel.com>

Modern PEBS hardware supports directly sampling XMM registers, then
large PEBS can be enabled for XMM registers just like other GPRs.
