Subject: [PATCH v1 5/6] drm/msm/gpu: Add ttbr0 to the memptrs
Date: Tue, 28 Jan 2020 15:16:09 -0700 [thread overview]
Message-ID: <1580249770-1088-6-git-send-email-jcrouse@codeaurora.org> (raw)
In-Reply-To: <1580249770-1088-1-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.
