全志H3 找不到Mali-400 GPU设备

问题描述：




使用的是友善之臂官网的 2017.11 uboot ，内核是LTS 5.15.101，参考了下面两个帖子的方法在内核进行了修改，但是无法在/dev设备列表下找到mali设备

gpu dts 配置：

		mali: gpu@1c40000 {
			compatible = "allwinner,sun8i-h3-mali", "arm,mali-400";
			reg = <0x01c40000 0x10000>;
			interrupts = <GIC_SPI 97 IRQ_TYPE_LEVEL_HIGH>,

				     <GIC_SPI 103 IRQ_TYPE_LEVEL_HIGH>,
				     <GIC_SPI 101 IRQ_TYPE_LEVEL_HIGH>;
			interrupt-names = "gp",
					  "gpmmu",
					  "pp0",
					  "ppmmu0",
					  "pp1",
					  "ppmmu1",
					  "pmu";
			clocks = <&ccu CLK_BUS_GPU>, <&ccu CLK_GPU>;
			clock-names = "bus", "core";
			resets = <&ccu RST_BUS_GPU>;
			operating-points-v2 = <&gpu_opp_table>;
		};
&mali {
	status = "okay";
};

内核设置：

Re: 全志H3 找不到Mali-400 GPU设备

后续：不知咋了，kmscube可以用了，但是还是没有mali结点。按照下面的全志官网链接进行用户端配置


https://linux-sunxi.org/Mali_binary_driver#Installing_the_UMP_.28Unified_Memory_Provider.29_userspace_library
https://linux-sunxi.org/Xorg






kmscube

奇怪的是，这个只能在串口输入才有效果，在Xshell连接以太网输入则说找不到设备

Xshell端连接网线：

h3_tinyscan@BIPLAB:~$ kmscube
no drm device found!
could not open drm device
failed to initialize legacy DRM

后面继续报错：

DRM_IOCTL_MODE_CREATE_DUMB failed: Cannot allocate memory
Segmentation fault





glmark2

glmark2：

Error: main: Could not initialize canvas

glmark2-drm：

root@BIPLAB:/home/h3_tinyscan/glmark2/build/src# glmark2-drm
Warning: DRM_CAP_ASYNC_PAGE_FLIP not supported, falling back to 'mailbox' mode for SwapInterval(0).

和kmscube报一样的错误

Re: 全志H3 找不到Mali-400 GPU设备

我又来更新了



找到问题，在设备树里面修改CMA大小，原来是64MB，改成128就可以成功运行了，参考下面几个连接。估计是因为使用2K屏的原因？


https://retropie.org.uk/forum/topic/24436/drm_ioctl_mode_create_dumb-failed-cannot-allocate-memory/18
https://community.toradex.com/t/problem-allocating-kms-memory-drm-ioctl-mode-create-dumb/16356
https://developer.toradex.com/software/linux-resources/linux-features/contiguous-memory-allocator-cma-linux/
https://blog.csdn.net/kickxxx/article/details/54631535



DTS设备树中的修改：

	reserved-memory {
		#address-cells = <1>;
		#size-cells = <1>;
		ranges;

		cma: linux,cma {
			compatible = "shared-dma-pool";	//采用DMA的方式使用预留的内存
			reusable;		//将预留的内存区域用作默认的CMA内存池
			size = <0x8000000>;//128MB
			alignment = <0x2000>;
			linux,cma-default;
		};
	};


glmaek2成功跑分：
