Subject: [PATCH v2 20/25] coresight: trbe: Request specific affinities for percpu IRQ
Date: Mon, 15 Sep 2025 09:56:57 +0100 [thread overview]
Message-ID: <20250915085702.519996-21-maz@kernel.org> (raw)
In-Reply-To: <20250915085702.519996-1-maz@kernel.org>
Let the TRBE driver request IRQs with an affinity mask matching
the TRBE implementation affinity.
