Subject: [PATCH 5.15 131/276] perf arm-spe: augment the data source type with neoverse_spe list
Date: Fri, 17 Oct 2025 16:53:44 +0200	[thread overview]
Message-ID: <20251017145147.264329126@linuxfoundation.org> (raw)
In-Reply-To: <20251017145142.382145055@linuxfoundation.org>

5.15-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Jing Zhang <renyu.zj@linux.alibaba.com>

[ Upstream commit 74a61d53a6d1ca1172d85964d15c83c2cc3670b3 ]

When synthesizing event with SPE data source, commit 4e6430cbb1a9("perf
arm-spe: Use SPE data source for neoverse cores") augment the type with
source information by MIDR. However, is_midr_in_range only compares the
first entry in neoverse_spe.

Change is_midr_in_range to is_midr_in_range_list to traverse the
neoverse_spe array so that all neoverse cores synthesize event with data
source packet.

Fixes: 4e6430cbb1a9f1dc ("perf arm-spe: Use SPE data source for neoverse cores")
