-Subject: [PATCH 104/134] printk: nbcon: Add driver_enter/driver_exit console
- callbacks
-Origin: https://www.kernel.org/pub/linux/kernel/projects/rt/6.6/older/patches-6.6.7-rt18.tar.xz
-
-Console drivers need some mechanism to synchronize between "normal
-driver activity" and console printing. For uart serial drivers it
-is the port lock. Other types of console drivers (network,
-graphics, USB) will need something as well.
-
-Provide 2 new mandatory nbcon console callbacks (driver_enter and
-driver_exit) to allow the consoles drivers to implement the
-appropriate synchronization. The callbacks are also expected to
-disable/enable migration.
