insmod bifrost_kbase.ko fail, can't run glmak2-es2

qianqian321

1. cd kernel,
   make menuconfig   CONFIG_MALI_BIFROST=m
2.  cd ../
./build.sh uboot

./build.sh kernel
./build.sh recovery
./mkfirmware.sh
./build.sh rawimg
3. use balena-etcher-electron-1.4.9-linux-x64 flash to SD, then power on the board
4. after boot, insmod bifrost_kbase.ko
encounter follow error:
dev_pm_opp_set_regulators: no regulator (shadercores) found: -19
devfreq fde60000.gpu: Couldn't update frequency transition information.

and can't run glmark2-es2：
arm_release_ver of this libmali is 'g2p0-01eac0', rk_so_ver is '4'.
arm_release_ver of this libmali is 'g2p0-01eac0', rk_so_ver is '4'.
Error: eglInitialize() failed with error: 0x3001
arm_release_ver of this libmali is 'g2p0-01eac0', rk_so_ver is '4'.
Error: eglInitialize() failed with error: 0x3001
Error: main: Could not initialize canvas

另外如果我采用built-in的方式，将mali直接编译进内核，即直接运行build.sh，这样启动后是可以运行的glmark2-es2的。

有没有人可以帮我看看，非常感谢

你一定要用模块方式？
你编译成模块后有没有把ko文件安装到板子里？

insmod bifrost_kbase.ko
我执行了这句

嗯，我要用模块的方式的

补充信息：
用模块加载的方式，在dmesg搜到的mali相关的打印和built-in的打印是一样的：

我试过了没问题，步骤如下：
SDK 更新到最新
CONFIG_MALI_BIFROST改为m并保存
./build.sh extboot 编译内核
sudo upgrade_tool di -b extboot.img 烧录内核
执行lsmod可以看到系统已经自动找到模块并已经在使用了，根本无需手动insmod
执行glmark2-es2没有问题

请问这个extboot.img是包含uboot, kernel, rootfs的吗？你也是通过烧到SD卡启动的吗？

Liuth

不是，extboot.img就是单纯内核，如果你要用sd卡，那你修改完成后执行./build.sh rawimg，编译完整固件

请问你这个烧录内核，是烧到开发板上吗，是可以只烧录内核的吗？文件系统呢？
