Subject: [Patch v10 02/23] perf/x86/intel: Enable large PEBS sampling for XMMs
Date: Tue, 21 Jul 2026 14:24:45 +0800 [thread overview]
Message-ID: <20260721062506.3745816-3-dapeng1.mi@linux.intel.com> (raw)
In-Reply-To: <20260721062506.3745816-1-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.
