[PATCH v5 0/1] platform/x86/tuxedo: Add virtual LampArray for TUXEDO NB04 devices

[Werner Sembach <wse@tuxedocomputers.com>]

Hi,
after some other work, picked this up again.
Only coding style changes vs v4.


I now got my feet a little wet with hid-bpf regarding something else, and
with that knowledge I would leave the long arrays in the beginning in the
kernel code for the time being:

sirius_16_ansii_kbl_mapping and sirius_16_iso_kbl_mapping are required
during initialization so they have to exist in the kernel code anyway.

report_descriptor will most likly not change even for future models and
afaik having report_descriptors in kernel drivers is not unheard of.

So the only things that could be meaningfully moved to a hid-bpf program
are the sirius_16_*_kbl_mapping_pos_* arrays. But for these is have to give
out some fallback value anyway for the case where a hid-bpf file is missing
or fails to load. So why not use real world values from my test device for
these values?

As soon as there is a future device that can use the same driver with just
these pos arrays different, then I would implement that change via a bpf
program instead of a change to the kernel driver.

Let me know if you too think this is a sensefull approach?


Another question: Would this patch need to wait for a userspace
implementation of lamp array before it can get accepted?


The folder structure and naming scheme with nb04 is im preparation for
other parts of tuxedo-drivers to be upstreamed. NB04 is one of the
board_vendor dmi strings on TUXEDO devices that aligns with which part of
tuxedo-drivers implements the features of that device. They are independent
of each other so I plan to put them in different subfolders to reflect
that.

Best regards,
Werner Sembach
