IMX6SOLO GPU GALCORE probe failed

I have a custom board with IMX6SOLO,

In which when I do an insmod galcore.ko I get the following error.

[ 612.024652] galcore: loading out-of-tree module taints kernel.
[ 612.040708] ERROR: could not get clock /soc/gpu@00130000:gpu3d_shader_clk(4)

[ 612.799677] galcore: probe of 130000.gpu failed with error -22

The Kernel Version I use is 4.9.123

The build environment is Buildroot.

My Device tree config is as follows

gpu@00130000 {
compatible = "fsl,imx6q-gpu";
reg = <0x00130000 0x4000>, <0x00134000 0x4000>,
<0x02204000 0x4000>, <0x10000000 0x0>,
<0x0 0x8000000>;
reg-names = "iobase_3d", "iobase_2d",
"iobase_vg", "phys_baseaddr",
"contiguous_mem";
interrupts = <0 9 IRQ_TYPE_LEVEL_HIGH>,
<0 10 IRQ_TYPE_LEVEL_HIGH>,
<0 11 IRQ_TYPE_LEVEL_HIGH>;
interrupt-names = "irq_3d", "irq_2d", "irq_vg";
clocks = <&clks IMX6QDL_CLK_GPU2D_AXI>, <&clks IMX6QDL_CLK_OPENVG_AXI>,
<&clks IMX6QDL_CLK_GPU3D_AXI>, <&clks IMX6QDL_CLK_GPU2D_CORE>,
<&clks IMX6QDL_CLK_GPU3D_CORE>, <&clks IMX6QDL_CLK_GPU3D_SHADER>;
clock-names = "gpu2d_axi_clk", "openvg_axi_clk",
"gpu3d_axi_clk", "gpu2d_clk",
"gpu3d_clk", "gpu3d_shader_clk";
resets = <&src 0>, <&src 3>, <&src 3>;
reset-names = "gpu3d", "gpu2d", "gpuvg";
power-domains = <&gpc 1>;
};

This works in Imx6Q and not in IMX6SOLO , can you please tell why its failing in IMX6SOLO

Thanks and Regards

Terry

Hi Terry

nxp does not support buildroot, also L4.9.123 does not support i.MX6 as described on

below link

https://www.nxp.com/design/software/embedded-software/i-mx-software/embedded-linux-for-i-mx-applications-processors:IMXLINUX?tab=In-Depth_Tab

One can test it on nxp sabresd board using any i.MX6 Demo Images from above link and

Chapter 5 Enabling Solo Emulation i.MX Linux User’s Guide

Best regards
igor
