[VIDEO] sbuslib: Disallow private mmaps.

2005-12-24T20:06:10+00:00

The COW semantics just do not make any sense especially
with the physically discontiguous I/O mappings possible
here.

[SPARC]: introduce a SPARC Kconfig symbol

2005-12-23T07:09:54+00:00

Introduce a Kconfig symbol SPARC that is defined on both the sparc and
sparc64 architectures.

This symbol makes some dependencies more readable.

[PATCH] Fix framebuffer console upside-down ywrap scrolling

2005-12-20T17:44:20+00:00

Whenever ywrap scrolling is selected together with 180 degree screen
rotation, 2.6.15-rc6 and earlier versions are broken.  fb_pan_display()
expects non-negative yoffsets, but ud_update_start() calls it with
yoffsets down to -(yres - font height).  This patch transforms yoffset
to the correct range 0 ...  vyres-1.

Some obviously unneeded parentheses are removed, too.

Verified with cyblafb, should be applied before 2.6.15-final because it
does fix the framebuffer rotation code introduced early in the 2.6.15
release cycle.

[PATCH] intelfb: Fix oops when changing video mode

2005-12-20T17:27:15+00:00

Reported by: janis huang (Bugzilla Bug 5747)

Fix on oops in intelfb.  Not sure what's happening, looks like
dinfo->name pointer is invalidated after initialization.  Remove
intelfb_get_fix, it's not needed and move the majority of the code to
the initialization routine.

[PATCH] fbdev: make pxafb more robust to errors with CONFIG_FB_PXA_PARAMETERS

2005-12-14T05:18:16+00:00

pxafb.c runs into an oops if CONFIG_FB_PXA_PARAMETERS is enabled and no
parameters are set in command line.  The following patch avoids this
problem.

[PATCH] fbdev: Fix incorrect unaligned access in little-endian machines

2005-12-13T06:31:17+00:00

The drawing function cfbfillrect does not work correctly when access is not
unsigned-long aligned.  It manifests as extra lines of pixels that are not
complete drawn.  Reversing the shift operator solves the problem, so I would
presume that this bug would manifest only on little endian machines.  The
function cfbcopyarea may also have this bug.

Aligned access should present no problems.

[PATCH] fbdev: Shift pixel value before entering loop in cfbimageblit

2005-12-13T06:31:17+00:00

In slow imageblit, the pixel value is shifted by a certain amount (dependent
on the bpp and endianness) for each iteration.  This is inefficient.  Better
do the shifting once before going into the loop.
