加载驱动时输出:
insmod: ERROR: could not insert module drivers/cpufreq/loongson3_cpufreq.ko: Operation not permitted
出错位置:
static int configure_cpufreq_info(void)
{
int ret;
union smc_message msg;
msg.cmd = CMD_GET_VERSION;
msg.extra = 0;
msg.complete = 0;
ret = do_service_request(&msg);
if (ret < 0 || msg.val < 0x1)
return -EPERM;
......
此处 msg.val
返回值为0
假如注释该处,则出错位置如下:
......
ret = cpufreq_register_driver(&loongson3_cpufreq_driver);
if (ret)
goto err;
......
此处 ret
返回值为-19
