Subject: [PATCH V13 07/14] perf/x86/intel: Do not enable large PEBS for events with aux actions or aux sampling
Date: Mon, 14 Oct 2024 13:51:17 +0300 [thread overview]
Message-ID: <20241014105124.24473-8-adrian.hunter@intel.com> (raw)
In-Reply-To: <20241014105124.24473-1-adrian.hunter@intel.com>
Events with aux actions or aux sampling expect the PMI to coincide with the
event, which does not happen for large PEBS, so do not enable large PEBS in
that case.
Signed-off-by: Adrian Hunter <adrian.hunter@intel.com>
Reviewed-by: Andi Kleen <ak@linux.intel.com>

Changes in V11:
Remove definition of has_aux_action() because it has
already been added as an inline function.
