Subject: [PATCH 12/12] perf/x86/intel: Rename NVL offcore_rsp attribute to offmodule_rsp
Date: Thu, 17 Sep 2026 09:52:34 +0800 [thread overview]
Message-ID: <20260917015234.981153-13-dapeng1.mi@linux.intel.com> (raw)
In-Reply-To: <20260917015234.981153-1-dapeng1.mi@linux.intel.com>
NVL introduces Offmodule Response events in place of the legacy
Offcore Response events, but it still exposes the inherited
offcore_rsp PMU attribute for programming the corresponding MSR data.
Rename the NVL PMU attribute to offmodule_rsp so the sysfs interface
matches the underlying event name and avoids user confusion.
