[PATCH 00/19] Ultrajoiner basic functionality series

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

 



This patch series attempts to implement basic support
for Ultrajoiner functionality.

Rev6:
-Upgrade the debugfs functionality to enable the joining of a
specified number of pipes.
-Modify the display helpers reliant on the pipe joiner mechanism
to use number of pipes joined, instead of joiner flag.
-Checkpatch fixes.

Rev7:
-Use struct intel_display, minor refactoring, and rebase.

Rev8:
-Address comments from Ville.
-Simplified debugfs for forcing joiner, and added option to disable
joiner.
-Modified the ultra/bigjoiner helpers as suggested by Ville. 
-Split few of the bigger patches as suggested.
