Subject: [PATCH 036/329] rt: Provide PREEMPT_RT_BASE config switch
|
|
Origin: https://www.kernel.org/pub/linux/kernel/projects/rt/4.19/older/patches-4.19.135-rt60.tar.xz
|
|
|
|
Introduce PREEMPT_RT_BASE which enables parts of
|
|
PREEMPT_RT_FULL. Forces interrupt threading and enables some of the RT
|
|
substitutions for testing.
