Subject: [PATCH 11/32] Documentation: thunderx2-pmu: Use /sys/bus/event_source/devices paths
Date: Tue, 4 Apr 2023 14:42:04 +0100 [thread overview]
Message-ID: <20230404134225.13408-12-Jonathan.Cameron@huawei.com> (raw)
In-Reply-To: <20230404134225.13408-1-Jonathan.Cameron@huawei.com>
To allow setting an appropriate parent for the struct pmu device
remove existing references to /sys/devices/ path.

@@ -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.
