Greetings:

I am relatively new to the dragon board 410c.

I am running the branch debian-qcom-dragonboard410c-20.07 from http://git.linaro.org/landing-teams/working/qualcomm/kernel.git which boots kernel 5.7.0-qcomlt-arm64

This 5.7.0 kernel and associated files does not compile cs-etm-decoder.c as symbol OCSD_GEN_TRC_ELEM_I_RANGE_NOPATH is undefined.

Mathieu Portier, a developer of the coresight package for aarch64 processors, says that this symbol has been defined in linux kernels >= 5.8

Is there a more recent branch of the kernel for the dragonboard 410c that is based on linux kernel 5.8 (or even 5.9-rc1)?

Thanks in advance, Robert Henry
