Antoine Coutant d6d0f73a2e board/khadas/vim3: add the path of the devicetree in extlinux.conf ... Without this patch, the devicetree used by linux at runtime is the u_boot devicetree. While using rusticl on the khadas vim3 board with the default extlinux.conf, mesa's panfrost driver return "gpu shed timeout" errors. Adding "devicetree /meson-g12b-khadas-vim3.dtb" to the extlinux.conf file solve the problem. Linux successfully boot with and without the change but without this patch the devicetree used by linux at runtime is the u-boot devicetree. The differences between the u-boot devicetree and the linux devicetree are: -The u-boot devicetree contains two more nodes than the linux devicetree. Those nodes are: - smbios : compatible option is set to "u-boot,sysinfo-smbios". - __symbols__ : present if -@ or --symbols is used during the devicetree compilation. -Most of u-boot devicetree nodes have a "phandle" property. -SoC and vpu have a "u-boot,dm-pre-reloc;" property. -Some aliases are different. -The u-boot operating points tables contains more nodes. The size difference between the u-boot devicetree and the linux devicetree is approximately 3.5kB. During runtime, the linux devicetree have the "phandle" and "u-boot,dm-pre-reloc;" properties and the smbios node. So, The runtime devicetree is the one from u-boot.
