Subject: [PATCH 07/13] tools headers uapi: Update drm/i915_drm.h
Date: Fri, 29 Mar 2019 10:37:55 -0300 [thread overview]
Message-ID: <20190329133801.21004-8-acme@kernel.org> (raw)
In-Reply-To: <20190329133801.21004-1-acme@kernel.org>
From: Arnaldo Carvalho de Melo <acme@redhat.com>
To get the changes in:
e46c2e99f600 ("drm/i915: Expose RPCS (SSEU) configuration to userspace (Gen11 only)")
That don't cause changes in the generated perf binaries.
To silence this perf build warning:
Warning: Kernel ABI header at 'tools/include/uapi/drm/i915_drm.h' differs from latest version at 'include/uapi/drm/i915_drm.h'
