Subject: [Intel-xe] [PATCH 13/17] drm/xe/oa: Multiplex PERF ops through a single PERF ioctl
Date: Thu,  7 Sep 2023 21:23:44 -0700	[thread overview]
Message-ID: <20230908042348.1592535-14-ashutosh.dixit@intel.com> (raw)
In-Reply-To: <20230908042348.1592535-1-ashutosh.dixit@intel.com>

Since we are already mulitplexing multiple perf counter stream types
through the PERF layer, it seems odd to retain separate ioctls for perf
op's (add/remove config). In fact it seems logical to also multiplex these
ops through a single PERF ioctl. This also affords greater flexibility to
add stream specific ops if needed for different perf stream types.
