Subject: [PATCH v3 14/16] drm/msm/gpu: Add ttbr0 to the memptrs
Date: Wed, 29 May 2019 14:54:50 -0600	[thread overview]
Message-ID: <1559163292-4792-15-git-send-email-jcrouse@codeaurora.org> (raw)
In-Reply-To: <1559163292-4792-1-git-send-email-jcrouse@codeaurora.org>

Targets that support per-instance pagetable switching will have to keep
track of which pagetable belongs to each instance to be able to recover
for preemption.
