AIO-3399-JD4开发板升级到Kernel 4.19,发现以下问题:
1. HDMI显示问题
rga2 irq invalid
voq.iommu irq错误导致HDMI图形界面使用鼠标异常
2、ramoops的dts配置不正确,需要修改为以下配置方式才能在新内核版本正常使能pstore
reserved-memory {
#address-cells = <2>;
#size-cells = <2>;
ranges;
drm_logo: drm-logo@00000000 {
compatible = "rockchip,drm-logo";
reg = <0x0 0x0 0x0 0x0>;
};
ramoops_mem: region@110000 {
compatible = "ramoops";
reg = <0x0 0x110000 0x0 0xf0000>;
record-size = <0x40000>; /* 注意不能配置为 <0 0x40000> */
console-size = <0x80000>;
ftrace-size = <0x00000>;
pmsg-size = <0x00000>;
};
}; |
