Subject: modesetting: Fix cirrus 24bpp breakage
|
|
References: bsc#1101699
|
|
|
|
The recent rewrite of modesetting driver broke the 24bpp support.
|
|
As typically found on cirrus KMS, it leads to a blank screen, spewing
|
|
the error like:
|
|
failed to add fb -22
|
|
(EE) modeset(0): failed to set mode: Invalid argument
|
|
|
|
The culript is that the wrong bpp value of the front buffer is passed
|
|
to drmModeAddFB(). Fix it by replacing with the back buffer bpp,
|
|
drmmode->kbpp.
