Subject: [PATCH 0/5] drm/panfrost: add Amlogic integration quirks
Date: Tue, 8 Sep 2020 17:18:48 +0200 [thread overview]
Message-ID: <20200908151853.4837-1-narmstrong@baylibre.com> (raw)
The T820, G31 & G52 GPUs integrated by Amlogic in the respective GXM, G12A/SM1 & G12B
SoCs needs a quirk in the PWR registers at the GPU reset time.
The coherency integration of the IOMMU in the Mali-G52 found in the Amlogic G12B SoCs
is broken and leads to constant and random faults from the IOMMU.
This serie adds the necessary quirks for the Amlogic integrated GPUs only.
Neil Armstrong (5):
iommu/io-pgtable-arm: Add BROKEN_NS quirk to disable shareability on
ARM LPAE
drm/panfrost: add support specifying pgtbl quirks
drm/panfrost: add support for reset quirk
drm/panfrost: add amlogic reset quirk callback
drm/panfrost: add Amlogic GPU integration quirks
