[PATCH v1 0/4] Improved logging

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This patch set does the following improvements:
1. Get time stamps available early in boot
2. Removes duplicated output on console during boot
3. Removes a dead zone, where after tty0 nothing is printed until
   ttyHV is regested; and even if we panic no messages are printed.

Here is example base output:

Fixed output:

  sparc64: initialize time early
  sparc64: allow platforms to say when to unload boot console
  sparc64: remove trailing white spaces
  sparc64: stop duplicating boot messages
