blu_spark_r134 release (A13 custom)
New build is up
I tested with lineage-20.0-20230307-nightly, kernel build may work with other ROMs that use similar device/kernel trees (confirm before flashing).
This is only for ROMS with A13 fw kernel patchset.
This kernel is tested for the 9 Pro but it's unified, so should work for the OP9 also.
For flashing and easy of install logging, Kernel Flasher
You can use Kernel Flasher/FKM download kernel feature, just import the link bellow in the app updates/flash section.
Download config: custom
Keep in mind:
I am mostly interested on debugging stuff with logs and reproducible steps to replicate the issue.
