Tool/software:
I am using AM3358. And this project uses SDK 6.0.0.7.
I want to change the CPU frequency for testing during use.
However, cpufreq is not visible in sysfs.
root@AptusLx:/sys/devices/system/cpu/cpu0# ls crash_notes of_node subsystem uevent crash_notes_size power topology
I remember changing the CPU frequency through sysfs before.
However, it is not present in AM3358.
Does AM3358 not support changing cpufreq?
If it can be changed, how?
Regards,
Seungmin Nam.
Dear Bin Liu,
I checked again and the project is using TI SDK v8.2.0.24.
And the config I use was modified based on am335x-evm.
I am attaching the config I am using. (config.zip (.config))
Looking at this config, it looks like CPUFREQ is enabled.
#
# CPU Frequency scaling
#
CONFIG_CPU_FREQ=y
CONFIG_CPU_FREQ_GOV_ATTR_SET=y
CONFIG_CPU_FREQ_GOV_COMMON=y
CONFIG_CPU_FREQ_STAT=y
CONFIG_CPU_FREQ_DEFAULT_GOV_PERFORMANCE=y
# CONFIG_CPU_FREQ_DEFAULT_GOV_POWERSAVE is not set
# CONFIG_CPU_FREQ_DEFAULT_GOV_USERSPACE is not set
# CONFIG_CPU_FREQ_DEFAULT_GOV_ONDEMAND is not set
# CONFIG_CPU_FREQ_DEFAULT_GOV_CONSERVATIVE is not set
CONFIG_CPU_FREQ_GOV_PERFORMANCE=y
CONFIG_CPU_FREQ_GOV_POWERSAVE=y
CONFIG_CPU_FREQ_GOV_USERSPACE=y
CONFIG_CPU_FREQ_GOV_ONDEMAND=y
CONFIG_CPU_FREQ_GOV_CONSERVATIVE=y
Do I need to enable other parts more?
Regards,
Seungmin Nam.
Hi,
Please double check with tisdk_am335x-evm_defconfig in the SDK kernel to see what else is missing. For example:
$ grep 'CPUFREQ.*=y' arch/arm/configs/tisdk_am335x-evm_defconfig
CONFIG_CPUFREQ_DT=y
CONFIG_CPUFREQ_DT_PLATDEV=y
CONFIG_ARM_TI_CPUFREQ=y
I just checked your config.zip, it seems you already have these options enabled.
Does the kernel boot log say anything wrong with CPUFREQ?
Dear Bin Liu.
Thank you for checking.
There is no CPUFREQ wrong log in the bootlog.
Attached boot log.

And I download
And I downloaded kernel 5.10.100 from git.
URL: git://git.ti.com/ti-linux-kernel/ti-linux-kernel.git
But tisdk_am335x-evm_defconfig is not visible.
Please tell me where I can check tisdk_am335x-evm_defconfig.
Regards,
Seungmin Nam.
tisdk_am335x-evm_defconfig is kernel defconfig, provided in the kernel source directory in the Processor SDK:
tisdk_am335x-evm_defconfig is kernel defconfig, provided in the kernel source directory in the Processor SDK:
Have you tried to build the kernel with this defconfig? Does cpufreq show up in sysfs with this defconfig?
Dear Bin Liu,
Even if you build the kernel with tisdk_am335x-evm_defconfig, sysfs is not visible.
Are there more things to consider in other settings?
And there is a cpufreq folder in sysfs. But there is no content in it.

Dear Bin Liu,
For debugging, I added the debug code to cpufreq-dt.c as shown below and checked.
<dev_err(&pdev->dev, "failed dt_cpufreq_early_init : %d\n", ret)>
static int dt_cpufreq_probe(struct platform_device *pdev)
{
struct cpufreq_dt_platform_data *data = dev_get_platdata(&pdev->dev);
int ret, cpu;
dev_info(&pdev->dev, "dt_cpufreq_probe\n");
/* Request resources early so we can return in case of -EPROBE_DEFER */
for_each_possible_cpu(cpu) {
ret = dt_cpufreq_early_init(&pdev->dev, cpu);
if (ret) {
dev_err(&pdev->dev, "failed dt_cpufreq_early_init : %d\n", ret);
goto err;
}
}
if (data) {
if (data->have_governor_per_policy)
dt_cpufreq_driver.flags |= CPUFREQ_HAVE_GOVERNOR_PER_POLICY;
dt_cpufreq_driver.resume = data->resume;
if (data->suspend)
dt_cpufreq_driver.suspend = data->suspend;
if (data->get_intermediate) {
dt_cpufreq_driver.target_intermediate = data->target_intermediate;
dt_cpufreq_driver.get_intermediate = data->get_intermediate;
}
}
ret = cpufreq_register_driver(&dt_cpufreq_driver);
if (ret) {
dev_err(&pdev->dev, "failed register driver: %d\n", ret);
goto err;
}
dev_info(&pdev->dev, "dt_cpufreq_probe complete\n");
return 0;
err:
dt_cpufreq_release();
return ret;
}
An error occurred in dt_cpufreq_early_init as shown below.

Isn't this the cause?
As a result, dt_cpufreq_probe did not work properly.
In the end, dt_cpufreq_probe complete was not executed.
Request you to check.
Regards,
Seungmin Nam.
Hi,
Isn't this the cause?
It likely is the cause.
I have a queue of work for this week, but will review the code next week to see what could cause this deferred probe.
Hi Seungmin,
Sorry, I haven't got a chance for this yet. I have a deadline due next Monday. I won't get on this until mid/later next week.
Hi Seungmin,
Sorry for my delayed response.
I just checked the function dt_cpufreq_early_init() in cpufreq-dt.c, it has 4 places where could return -EPROBE_DEFER (-517). Can you please add a dev_err() in these places to see which function call failed?
