Subject: [Intel-gfx] [PATCH 21/27] drm/i915/pxp: Add i915 trace logs for PXP operations
Date: Fri, 13 Nov 2020 17:45:31 -0800	[thread overview]
Message-ID: <20201114014537.25495-21-sean.z.huang@intel.com> (raw)
In-Reply-To: <20201114014537.25495-1-sean.z.huang@intel.com>

From: "Huang, Sean Z" <sean.z.huang@intel.com>

Add several i915 trace logs for PXP calls for debugging or
performance measurement, including:
(1) PXP ioctl
(2) PXP teardown callbacks

To trun on this feature, we need to set
"CONFIG_DRM_I915_LOW_LEVEL_TRACEPOINTS=y" in .config for compiling
the Linux kernel.
