A133 linux5.4 GPU（ge8300）无法使用

afaf LV 4

A133 linux5.4 下的 GPU 无法正常使用（编译为 linux 固件，非安卓固件）

insmod pvrsrvkm.ko 打印 read BVNC 0.0.0.0，无法读取到 BVNC，指定使用 22.102.54.38

接着跑 QT 例程时打印读取不到固件 rgx.fw.22.102.54.38。

将固件 rgx.fw.22.102.54.38 放到 /lib/firmware/ 下，重启系统后再次安装 pvrsrvkm.ko 后跑 QT 例程，dmesg 可看到下面的打印信息

好像是说 gpu 电源没起来？处于 idle 模式？

查看源码，有一些提示

直接翻译注释

当bFirmwareStarted失败时，可以通过执行以下调试转储获得一些信息，但不幸的是，如果未启动的原因是GPU电源未打开，则可能存在潜在危险。
然而，如果我们已经到达这一点，系统层已经返回没有错误，我们假设GPU电源确实是ON。

设备树 board.dts 配置如下

&gpu {
  gpu_idle = <0>;
  dvfs_status = <1>;
  pll_rate = <504000>;
  independent_power = <0>;
  operating-points = <
    /* KHz   uV */
    504000 950000
    472500 950000
    441000 950000
    252000 950000
   >;
   gpu-supply = <&reg_dcdc4>;
};

linux menuconfig：
1、打开 DRM

2、选择 GPU 为 ge8300

有大神知道怎么搞吗，linux5.4 下无法使用 gpu，而编译安卓的固件就可以，Linux的固件就不行。

GPU 安卓部分是正常的，linux 部分才有这个问题，我使用的是 linux，不适用安卓。
