Subject: [PATCH v3 19/26] perf: arm_spe_pmu: Request specific affinities for percpu IRQ
Date: Mon, 22 Sep 2025 09:28:26 +0100 [thread overview]
Message-ID: <20250922082833.2038905-20-maz@kernel.org> (raw)
In-Reply-To: <20250922082833.2038905-1-maz@kernel.org>
Let the SPE driver request IRQs with an affinity mask matching
the SPE implementation affinity.
