Subject: [PATCH 2/3] drm/i915: Mark the kernel as tainted if we fail the preproduction check
Date: Thu, 26 Jan 2017 12:50:29 +0000 [thread overview]
Message-ID: <20170126125030.30815-2-chris@chris-wilson.co.uk> (raw)
In-Reply-To: <20170126125030.30815-1-chris@chris-wilson.co.uk>
Preproduction sdv are not supported beyond the release of production
hardware, and continued use is ill-advised. Mark the kernel as tainted
to reinforce the error.
