I saw there’d been a discussion about the different btw kernel/distros officially supported by Qualcomm vs ones supported by Linaro : Can anyone explain to me what essential differences between linaro and codeaurora?
I understand that the Qualcomm’s resource is not easy and straight forward to access (there might also separated patches & stuffs to make the board run with the downstream kernel of Qualcomm). Therefore, for Qualcomm RB5, I would like to know if there’s limitation in term of HW support if the upstream kernel (i.e. the one supported by Linaro) is used, please ?
For example, I would like to patch in order to enable the Fully Preempt Kernel. And I would assume that this task would take less effort by using the Linaro upstream kernel (with example of Dragonboard845c-RB3) than the Qualcomm kernel. But I worry that by this way I could not have full HW functional especially for advance HW blocks such as image processing or deep learning, etc.
I’m looking forward to hearing from you.
Thanks in advance and best regards,
