Hi all,

This regarding to the plan to build coresight drivers as Kernel module. Currently, it doesn't support that. I noticed there's some patch to add the ability to build as module but that patch doesn't end to be merged.

I'd like to know whether anyone is working on this or has plan for this.

A fellow from Suse sent me a patchset in January to do just that[1]. I don't know where his work is currently at.

This is something that has been attempted at least a couple of times in the past. The challenge has always been to make sure any single driver can be removed without having an effect on other drivers that may currently depend on them (or at any time in the future).

Thanks, Mathieu

I'm interesting in this since there's some trend on mobile device especially Android device that all drivers should be built as Kernel modules. Coresight drivers are important for mobile device to debug SW/HW issues.
