I'm working on the kernel of my xiaomi device. However, whenever I start it, it soft reboots to recovery. 

I'm guessing a kernel oops occur.

I wanted to ask how to read kernel debug messages of the last run ?

In my Nexus 5, I have /proc/last_kmsg which contains the messages from the last run.

However, in my xiaomi kernel tree, that proc entry is removed.

Responsible commit - https://github.com/omerjerk/android_kernel_xiaomi_ferrari/commit/15d76446205710ddfcba6cc9156c7883074f84b1

It says that functionality has been moved to pstore. 

But I'm not able to get how to exactly read the debug messages of the last run.

Thanks
