I am software engineer in charge of BSP (Samsung SOC vendor). Recently, Google introduced GKI from Android 11(R) version. So we can't modified kernel code except module drivers. Coresight drivers doesn't support module. I need the module support because our SoC should set value to vendor specific register to run ETMv4. And in GKI, ETM has disabled in recommend defconfig. So if we use ETM in Android 12(S), it should support module. Could you support the modules of the coresight drivers? ^ permalink raw reply [flat|nested] 2+ messages in thread

There have been multiple patchset submitted to do that, the latest one last week [1]. I encourage you to review and test the work.
