From c617ec63339222f3a44d73e36677a9acc8954ccd Mon Sep 17 00:00:00 2001 From: John Ogness Date: Thu, 19 Nov 2020 02:41:21 +0000 Subject: [PATCH 1/2] [PATCH 1/2] printk: add support for lockless ringbuffer * Required for kernel 5.10 Linux 5.10 introduces a new lockless ringbuffer. The new ringbuffer is structured completely different to the previous iterations. Add support for retrieving the ringbuffer from debug information and/or using vmcoreinfo. The new ringbuffer is detected based on the availability of the "prb" symbol.
