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.
To allow setting an appropriate parent for the struct pmu device remove existing references to /sys/devices/ path. Signed-off-by: Jonathan Cameron <Jonathan.Cameron@huawei.com> --- Documentation/admin-guide/perf/thunderx2-pmu.rst | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)
