This patchset adds the support of the ARM Mali G57 MC2 GPU (Valhall-JM, dual core), integrated in the Mediatek MT8370 SoC, to the panfrost driver and to the mt8370.dtsi include file. I've tested this patchset on a Mediatek Genio 510 EVK board, with a kernel based on linux-next (tag: next-20250207) plus [1] patch (not needed for building, only for testing to avoid boot issues on this board). The panfrost driver probed with the following messages: ``` panfrost 13000000.gpu: clock rate = 390000000 panfrost 13000000.gpu: mali-g57 id 0x9093 major 0x0 minor 0x0 status 0x0 panfrost 13000000.gpu: features: 00000000,000019f7, issues: 00000003, 80000400 panfrost 13000000.gpu: Features: L2:0x08130206 Shader:0x00000000 Tiler:0x00000809 Mem:0x1 MMU:0x00002830 AS:0xff JS:0x7 panfrost 13000000.gpu: shader_present=0x5 l2_present=0x1 [drm] Initialized panfrost 1.3.0 for 13000000.gpu on minor 0 ``` [1] https://lore.kernel.org/all/20250124191644.2309790-1-robh@xxxxxxxxxx/ Signed-off-by: Louis-Alexis Eyraud <louisalexis.eyraud@xxxxxxxxxxxxx> --- Changes in v3: - Rebased on linux-next (tag: next-20250207) - Remove prerequisite change/patch ids - Reword commit messages to better explicit compatible needs - Link to v2: https://lore.kernel.org/r/20250130-mt8370-enable-gpu-v2-0-c154d0815db5@xxxxxxxxxxxxx Changes in v2: - Rework "drm/panfrost: Add support for Mali on the MT8370 SoC" to avoid data structure duplication, as requested by Krzysztof Kozlowski - Reword commit messages to use imperative mood and make new compatible need more explicit - Link to v1: https://lore.kernel.org/r/20250116-mt8370-enable-gpu-v1-0-0a6b78e925c8@xxxxxxxxxxxxx --- Louis-Alexis Eyraud (3): dt-bindings: gpu: mali-bifrost: Add compatible for MT8370 SoC drm/panfrost: Add support for Mali on the MT8370 SoC arm64: dts: mediatek: mt8370: Enable gpu support Documentation/devicetree/bindings/gpu/arm,mali-bifrost.yaml | 5 ++++- arch/arm64/boot/dts/mediatek/mt8370.dtsi | 9 +++++++++ drivers/gpu/drm/panfrost/panfrost_drv.c | 1 + 3 files changed, 14 insertions(+), 1 deletion(-) --- base-commit: ed58d103e6da15a442ff87567898768dc3a66987 change-id: 20250115-mt8370-enable-gpu-3b6f595fa63d Best regards, -- Louis-Alexis Eyraud <louisalexis.eyraud@xxxxxxxxxxxxx>
