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 testing this patchset on a Mediatek Genio 510 EVK board, with a kernel based on linux-next (tag: next-20250113) plus [1] patchset. 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/linux-mediatek/20250115-dts_mt8370-genio-510-v2-0-fc9b01d08834@xxxxxxxxxxxxx/ Signed-off-by: Louis-Alexis Eyraud <louisalexis.eyraud@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 | 10 ++++++++++ 3 files changed, 23 insertions(+), 1 deletion(-) --- base-commit: 37136bf5c3a6f6b686d74f41837a6406bec6b7bc change-id: 20250115-mt8370-enable-gpu-3b6f595fa63d prerequisite-change-id: 20250113-dts_mt8370-genio-510-3560b8010ba9:v2 prerequisite-patch-id: af53ae39240467340ac4c9cdbc8fdd949c5457a2 prerequisite-patch-id: ca07485956f81c1a40029b48d2b4bcf00d74fc13 prerequisite-patch-id: c34d9870b2c61d87ad8a6facba13d8970682e679 prerequisite-patch-id: 48784acdcdd8b886fdec9f21c9cb88abb327e2e1 Best regards, -- Louis-Alexis Eyraud <louisalexis.eyraud@xxxxxxxxxxxxx>
