For example, Intel Sapphire Rapidsserver supports the discovery mechanism. Without the platform-specificsupport, an uncore PMU is named by a type ID plus a box ID, e.g.,uncore_type_0_0, because the real name of the uncore PMU cannot beretrieved from the discovery table. With the platform-specific supportlater, perf has the mapping information from a type ID to a specificuncore unit. Just like the previous platforms, the uncore PMU is namedby the real PMU name, e.g., uncore_cha_0. The user scripts which workwell with the old numeric name may not work anymore.Add a new attribute "alias" to indicate the old numeric name. Thefollowing userspace perf tool patch will handle both names. The userscripts should work properly with the updated perf tool.Signed-off-by: Kan Liang <kan.liang@linux.intel.com>Signed-off-by: Peter Zijlstra (Intel) <peterz@infradead.org>Reviewed-by: Andi Kleen <ak@linux.intel.com>Link: https://lore.kernel.org/r/1625087320-194204-13-git-send-email-kan.liang@linux.intel.com List of files: /linux-6.15/Documentation/ABI/testing/sysfs-bus-event_source-devices-uncore Wed, 30 Jun 2021 21:08:36 +0000 Kan Liang <kan.liang@linux.intel.com>
