KeyError: 'pwm1_enable'

[GnomeBeans]

I swapped to a 9070 xt and I'm getting this error.

Traceback (most recent call last):

can you ls the hwmon directory for that device?

ls /sys/class/hwmon/hwmon<number>

if you give me the output of the following 2 commands, i can probably work it out myself

ls /sys/class/hwmon/hwmon*
cat /sys/class/hwmon/hwmon*/name

[GnomeBeans]

Yes. I looked around and tried to fix the python but no luck. I kept thinking it was looking in hwmon6 for pwm1_enable but I really have no idea. Heres the information.

Sorry for the delay.

ls /sys/class/hwmon/hwmon6/device/gpu_od/fan_ctrl

if you get a list of files something like:

acoustic_limit_rpm_threshold
acoustic_target_rpm_threshold
fan_curve
fan_minimum_pwm
fan_target_temperature

We might have something to go with here. Looks like RDNA4 moved the fan control sysfs files, and also changed the format... yay... 😄

[GnomeBeans]

Thanks for your support! This isn’t a critical need, but I do really like the tool — it’s powerful without requiring a fancy UI installation.

Here’s what I have in the requested directory:

acoustic_limit_rpm_threshold
acoustic_target_rpm_threshold
fan_curve
fan_minimum_pwm
fan_target_temperature
fan_zero_rpm_enable

[chestm007]

This isnt going to be overly straightforward as none of my hardware is this new haha, ill slap it on my todo list as it looks like an interesting task to implement!

Let me know if I can provide any details that might help and I can test as well.

I upgraded to a 9060 XT (with a 9600X CPU) and am getting the same error.

I assume you'd want me to look at
ls /sys/class/hwmon/hwmon2/device/gpu_od/fan_ctrl
and
ls /sys/class/hwmon/hwmon3/device/gpu_od/fan_ctrl

but I get:
ls: cannot access '/sys/class/hwmon/hwmon2/device/gpu_od/fan_ctrl': No such file or directory
for both of them.

In fact I can't even find a gpu_od directory anywhere...
