Display got wrong rotation after hid_sensor_accel_3d is loaded

Display got wrong rotation after hid_sensor_accel_3d is loaded

[AceLan Kao]

Hi all,

I'm working on a new platform which comes with an accelerator meter.
It's a STMicroelectronics LSM6DS3US accelerator meter, it doesn't use
st_sensors driver, but hid_sensor_accel_3d.
After hid_sensor_accel_3d is loaded, the display becomes upside down,
so I tried to add some code to make it become normal.(ACCEL_X should
have the same modification)

I don't know how to fix this in a correct way, please give me some hints.
Thanks.

This needs to be done as a quirk, either by applying a quirk for the
HID descriptors (which should have a definition of the scale, which
would be negative for this device), or in user-space in systemd's hwdb
database, which your user-space consumers need to take care of:
https://github.com/systemd/systemd/blob/master/hwdb.d/60-sensor.hwdb

Hi Bastien,

Thanks for your suggestion.
I just tried to add the following line into
/lib/udev/hwdb.d/60-sensor.hwdb and got the correct screen rotation.
But the cursor is still un-rotated, the cursor is drawn upside down,
and its coordinates are inverted.

#########################################
# STMicro
#########################################
sensor:modalias:platform:platform:HID-SENSOR-200073
 ACCEL_MOUNT_MATRIX=-1, 0, 0; 0, -1, 0; 0, 0, 1

It looks like we should introduce a quirk into hid_sensor_accel_3d driver.
There are 3 different scale variables in hid_sensor_accel_3d, but I
don't see any of them would work the way I want.
Do you mean to introduce new scale variables?

   drivers/iio/accel/hid-sensor-accel-3d.c:34:     int scale_pre_decml;
   drivers/iio/accel/hid-sensor-accel-3d.c:35:     int scale_post_decml;
   drivers/iio/accel/hid-sensor-accel-3d.c:36:     int scale_precision;

Hi Kao,

Is this device sold with Windows?
Can you send full report descriptor (You can get from
/sys/kernel/debug/hid)?

Thanks,
Srinivas

Yes, this machine will be sold with Windows, but currently we didn't
hear any issues from Windows side.
Here is the rdesc I found under /sys/kernel/debug/hid

BTW, we're trying to push BIOS to provide some useful info about the
orientation of the sensor, so that we don't have to list those
machines in the driver.

There are custom sensors, which probably getting used by Windows
instead of accel_3d. I didn't see any special fields in accel_3d.

Re: Display got wrong rotation after hid_sensor_accel_3d is loaded

Hi all,

Quick update, ODM BIOS admits it's a BIOS issue, and they will fix
this from BIOS side.
Thanks all.
