@ -22,7 +22,7 @@ The thunderx2_pmu driver registers per-socket perf PMUs for the DMC and
L3C devices. Each PMU can be used to count up to 4 (DMC/L3C) or up to 8
(CCPI2) events simultaneously. The PMUs provide a description of their
available events and configuration options under sysfs, see
/sys/devices/uncore_<l3c_S/dmc_S/ccpi2_S/>; S is the socket id.
/sys/bus/event_source/devices/uncore_<l3c_S/dmc_S/ccpi2_S/>; S is the socket id.
The driver does not support sampling, therefore "perf record" will not
work. Per-task perf sessions are also not supported.
