Cover letter [PATCH 0/3] perf/arm_dsu: Support newer DSUs
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.
