Subject: [PATCH] fb: Fix invalid bpp for 24bit depth window
|
|
|
|
We have a hack in fb layer for a 24bpp screen to use 32bpp images, and
|
|
fbCreateWindow() replaces its drawable.bitsPerPixel field
|
|
appropriately. But, the problem is that it always replaces when 32bpp
|
|
is passed. If the depth is 32, this results in bpp < depth, which is
|
|
actually invalid.
|
|
|
|
Meanwhile, fbCreatePixmap() has a more check and it creates with 24bpp
|
|
only when the passed depth <= 24 for avoiding such a problem.
|
|
|
|
This oneliner patch just adds the similar check in fbCreateWindow().
|
|
This (hopefully) fixes the long-standing broken graphics mess of
|
|
cirrus KMS with 24bpp.
