Subject: [Intel-gfx] [PATCH 06/20] drm/i915/gt: Prevent allocation on a banned context
Date: Thu, 27 Feb 2020 08:57:09 +0000 [thread overview]
Message-ID: <20200227085723.1961649-6-chris@chris-wilson.co.uk> (raw)
In-Reply-To: <20200227085723.1961649-1-chris@chris-wilson.co.uk>
If a context is banned even before we submit our first request to it,
report the failure before we attempt to allocate any resources for the
context.
