Subject: [PATCH v2 0/7] drm/panfrost: Add heap and no execute buffer allocation
Date: Wed, 24 Jul 2019 19:09:56 -0600	[thread overview]
Message-ID: <20190725011003.30837-1-robh@kernel.org> (raw)

This series adds new BO allocation flags PANFROST_BO_HEAP and
PANFROST_BO_NOEXEC. The heap allocations are paged in on GPU page faults.

This is based on drm-misc-next. A branch is here[1].
