Subject: [PATCH 0/3] perf/arm_dsu: Support newer DSUs
Date: Mon, 15 Dec 2025 13:04:57 +0000 [thread overview]
Message-ID: <cover.1765802897.git.robin.murphy@arm.com> (raw)
Hi all,
DSU-110 and 120 have been out for a while, and although they continue
to share the same basic system register interface, they have subtle
functional changes that require a little attention to support properly.
And while DSUs still aren't widely exposed in current systems, at least
some folks do apparently care.
Sanity-checked on DSU-120 in FPGA, and original DSU on Rockchip RK3566
with TF-A hacked to set ACTLR_EL3.CLUSTERPMUEN.
Cheers,
Robin.
