TMDSEVM572X: TIDL部分的Insufficient OpenCL global memory问题

我咨询相关工程师后再给您回复。

你好。

我今天只对dts文件做以下修改：

（1）cmem_block_mem@a0000000部分，“reg = <0x0 0xa0000000 0x0 0xc000000>;”改为“reg = <0x0 0xa0000000 0x0 0x18000000>;”

（2）cmem_block@0部分，“cmem-buf-pools = <0x1 0x0 0xc000000>;”改为“cmem-buf-pools = <0x1 0x0 0x18000000>;”

dts文件转换dtb文件无报错，但是当我重启设备后，CMEM大小依旧没有变化。希望得到对应解决方案。

谢谢！

请将您目前设备树中memory部分的配置直接贴上来，谢谢！

memory@0 {
		device_type = "memory";
		reg = <0x0 0x80000000 0x0 0x80000000>;
	};

	reserved-memory {
		#address-cells = <0x2>;
		#size-cells = <0x2>;
		ranges;

		ipu2-memory@95800000 {
			compatible = "shared-dma-pool";
			reg = <0x0 0x95800000 0x0 0x3800000>;
			reusable;
			status = "okay";
			phandle = <0xa0>;
		};

		dsp1-memory@99000000 {
			compatible = "shared-dma-pool";
			reg = <0x0 0x99000000 0x0 0x4000000>;
			reusable;
			status = "okay";
			phandle = <0xa6>;
		};

		ipu1-memory@9d000000 {
			compatible = "shared-dma-pool";
			reg = <0x0 0x9d000000 0x0 0x2000000>;
			status = "okay";
			no-map;
			phandle = <0x99>;
		};

		dsp2-memory@9f000000 {
			compatible = "shared-dma-pool";
			reg = <0x0 0x9f000000 0x0 0x800000>;
			reusable;
			status = "okay";
			phandle = <0xda>;
		};

		mmu-early-page-tables@95700000 {
			reg = <0x0 0x95700000 0x0 0x100000>;
			no-map;
		};

		cmem_block_mem@a0000000 {
			reg = <0x0 0xa0000000 0x0 0x18000000>;
			no-map;
			status = "okay";
			phandle = <0xed>;
		};

		cmem_block_mem@40500000 {
			reg = <0x0 0x40500000 0x0 0x100000>;
			no-map;
			status = "okay";
			phandle = <0xee>;
		};
	};

以上修改了cmem_block_mem@a0000000部分。只修改了reg语句。

	cmem {
		compatible = "ti,cmem";
		#address-cells = <0x1>;
		#size-cells = <0x0>;
		#pool-size-cells = <0x2>;
		status = "okay";

		cmem_block@0 {
			reg = <0x0>;
			memory-region = <0xed>;
			cmem-buf-pools = <0x1 0x0 0x18000000>;
			phandle = <0x211>;
		};

		cmem_block@1 {
			reg = <0x1>;
			memory-region = <0xee>;
			phandle = <0x212>;
		};
	};

以上修改了cmem_block@0部分。只修改了cmem-buf-pools语句。

仅修改以上两个语句，则am57xx-evm.dts和am57xx-evm-reva3.dts都可顺利转换为dtb文件。

谢谢帮助。
