Subject: [Patch v7 03/24] perf/x86/intel: Enable large PEBS sampling for XMMs
Date: Tue, 24 Mar 2026 08:40:57 +0800	[thread overview]
Message-ID: <20260324004118.3772171-4-dapeng1.mi@linux.intel.com> (raw)
In-Reply-To: <20260324004118.3772171-1-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.
