Hi Folks,
Cannot get the accelerometer sensor to work. Obviously the kernel module is not loaded and trying to load it manually amd_sfhtp_hid gives:

Any idea how to get the kernel module amd_sfhtp_hid is highly appreciated. Thanks in advance.

Where did you find that you need to load this module ?
I cannot find any module with that name even in the most recent kernel (6.1). The closest one is amd_sfh and lsmod shows it is already loaded.

Thanks for the reply @p.H
I got the idea from here https://bbs.archlinux.org/viewtopic.php?id=252815.
Actually the problem is I have this accelometer sensor:

Code: Select all

03:00.7 Signal processing controller: Advanced Micro Devices, Inc. [AMD] Raven/Raven2/Renoir Sensor Fusion Hub

and in the past on the same version of debian I had these files:

Code: Select all

/sys/devices/0020:1022:0001.0001/HID-SENSOR-200073.1.auto/iio:device0/in_accel_x_raw
/sys/devices/0020:1022:0001.0001/HID-SENSOR-200073.1.auto/iio:device0/in_accel_y_raw
/sys/devices/0020:1022:0001.0001/HID-SENSOR-200073.1.auto/iio:device0/in_accel_z_raw

Now after recent updates they have disappeared. That is the problem. I want to get the sensor to work. Any idea is highly appreciated.

Did it worked with non-backported kernel?
Try to boot with previous kernel to test for regression.

Thanks for the reply. Tried:

Code: Select all

linux-headers-5.10.0-18-amd64
linux-headers-5.10.0-18-common
linux-image-5.10.0-18-amd64
linux-kbuild-5.10

linux-headers-5.18.0-0.deb11.4-amd64
linux-headers-5.18.0-0.deb11.4-common
linux-image-5.18.0-0.deb11.4-amd64
linux-kbuild-5.18

linux-headers-6.0.0-0.deb11.2-amd64
linux-headers-6.0.0-0.deb11.2-common
linux-image-6.0.0-0.deb11.2-amd64
linux-kbuild-6.0

None fixed the issue. Plus, on 5.10 I don't have suspend (That's why I use backports in the first place). Still any ideas?

IIUC this thread is about an early driver version which was not merged as is into the mainline kernel. The module name was different when it was eventually merged in Linux 5.11.

Thanks for the reply. I see it talks about the patches being merged into 5.20. As I wrote above, I have tried:

Code: Select all

linux-headers-5.10.0-18-amd64
linux-headers-5.10.0-18-common
linux-image-5.10.0-18-amd64
linux-kbuild-5.10

linux-headers-5.18.0-0.deb11.4-amd64
linux-headers-5.18.0-0.deb11.4-common
linux-image-5.18.0-0.deb11.4-amd64
linux-kbuild-5.18

linux-headers-6.0.0-0.deb11.2-amd64
linux-headers-6.0.0-0.deb11.2-common
linux-image-6.0.0-0.deb11.2-amd64
linux-kbuild-6.0

So why is that it still does not work for me? And it used to work before on the same computer and same installation. It suddenly stopped working. I think it should be some config file somewhere disabled this?

Can you send a system log's extract of previous booting with a kernel when the sensor has been recognized ?

Anyway, the kernel module's name should be amd_sfh.ko and it's in the following kernels from debian stable-backports: https://packages.debian.org/search?mode ... amd_sfh.ko . Try to probe the hardware using this kernel module.

Unfortunately it not possible. I don't have those logs anymore (/var/log is mounted as tmpfs) and I don't know which version of which package to roll back to, to make it work again.

The module is already loaded. Unloading it with rmmod and then modprobe again also did not solve the problem. Any other ideas?
