> I have attached an ACPI Dump as requested.
Thank you. First of all sorry for asking for one needlessly I now see there
already was one attached to this bug.
So the ACPI firmware node describing the MXC6655 does contain a ROTM method
like we have also seen on BOSC0200 and KIOX000A ACPI firmware nodes and that
does correctly describe the rotation matrix of the accelerometer if I compare
it with your hwdb, the only thing which is different is that it inverts the Z
axis, but that axis is not used for rotation so chances are that inverting it
is actually correct for apps which do care about it.
I have prepared a set of patches:
https://lore.kernel.org/linux-iio/20240417164616.74651-1-hdegoede@redhat.com/
Which adds ROTM parsing to the mxc4005 driver. I have started a F39 kernel
build with the original set of fixes + these patches on top here:
https://koji.fedoraproject.org/koji/taskinfo?taskID=116515238
This is still building atm, this should complete building in a couple of hours.
Once this is done building please give this a test run. Here are some
instructions for directly installing a kernel from koji (Fedora's buildsystem):
https://fedorapeople.org/~jwrdegoede/kernel-test-instructions.txt
If you don't have time to test the next couple of days, please at least
download the kernel rpms.
After booting this kernel you should be able to do:
cat /sys/bus/iio/devices/iio:device0/in_mount_matrix
(assuming iio:device0 is the accel)
And this should then show:
0, -1, 0; -1, 0, 0; 0, 0, -1
and you could drop the hwdb entry for the tablet if you want since
iio-sensor-proxy should now pick it up from this file (hwdb entries will
override the contents of this file so that broken firmware settings can be
fixed).
