Dear Linux folks,
Currently, on Dell systems with the accelerometer lis3lv02d, its I²C
address needs to be added to `dell_lis3lv02d_devices[]` in
`drivers/i2c/busses/i2c-i801.c`.
In Linux 6.7-rc6 that array has nine elements, so only a small fraction
of all Dell notebooks is listed. Searching the Linux logs uploaded to
the Linux hardware database from May 2023 [1], there are around 129
devices without support in the Linux kernel version the upload was done
with.
Do you know, how the Microsoft Windows driver is doing this? Is it
hard-coded there too, or can it be deduced somehow, for example from the
ACPI tables?
I added some Kai-Heng and Hans to Cc as they might have contact. Dell
offers or offered quite a few of the models with official Ubuntu
support, so I would have hoped to have a generic solution for this.
Maybe Mario can also forward it to the Dell team.
Kind regards,
Paul
