video: move fbdev to drivers/video/fbdev

2014-04-17T05:10:19+00:00

The drivers/video directory is a mess. It contains generic video related
files, directories for backlight, console, linux logo, lots of fbdev
device drivers, fbdev framework files.

Make some order into the chaos by creating drivers/video/fbdev
directory, and move all fbdev related files there.

No functionality is changed, although I guess it is possible that some
subtle Makefile build order related issue could be created by this
patch.

mach64: fix cursor when character width is not a multiple of 8 pixels

2014-02-11T13:01:04+00:00

This patch fixes the hardware cursor on mach64 when font width is not a
multiple of 8 pixels.

If you load such a font, the cursor is expanded to the next 8-byte
boundary and a part of the next character after the cursor is not
visible.
For example, when you load a font with 12-pixel width, the cursor width
is 16 pixels and when the cursor is displayed, 4 pixels of the next
character are not visible.

The reason is this: atyfb_cursor is called with proper parameters to
load an image that is 12-pixel wide. However, the number is aligned on
the next 8-pixel boundary on the line
"unsigned int width = (cursor->image.width + 7) >> 3;" and the whole
function acts as it is was loading a 16-pixel image.

This patch fixes it so that the value written to the framebuffer is
padded with 0xaaaa (the transparent pattern) when the image size it not
a multiple of 8 pixels. The transparent pattern causes that the cursor
will not interfere with the next character.

atyfb: set FBINFO_READS_FAST

2014-02-11T13:01:04+00:00

Set FBINFO_READS_FAST so that the console code uses scrolling instead of
rewriting. This improves scrolling speed.

mach64: use unaligned access

2014-02-11T13:01:04+00:00

This patch fixes mach64 to use unaligned access to the font bitmap.

This fixes unaligned access warning on sparc64 when 14x8 font is loaded.

On x86(64), unaligned access is handled in hardware, so both functions
le32_to_cpup and get_unaligned_le32 perform the same operation.

On RISC machines, unaligned access is not handled in hardware, so we
better use get_unaligned_le32 to avoid the unaligned trap and warning.

atyfb: remove resolution limit 1600

2014-02-11T13:01:04+00:00

The card works fine in 1980x1080 resolution. Therefore, there is no need
to limit the resolution to 1600 pixels.

drivers/video/aty/aty128fb.c: fix a warning pertaining to the aty128fb backlight variable

2014-01-24T00:36:55+00:00

Fix the following warning in the aty128fb driver:

	drivers/video/aty/aty128fb.c:363:12: warning: 'backlight' defined but not used [-Wunused-variable]
	 static int backlight = 0;
		    ^

as the variable's value is only read if CONFIG_FB_ATY128_BACKLIGHT=y.  The
variable is also set if MODULE is unset[*].

[*] I wonder if the conditional wrapper around aty128fb_setup() should be
    using CONFIG_MODULE rather than MODULE.

The power management code is only used on X86 and PowerMac. To prevent
the compiler from warning about unused code, only build when PM and one
of X86 or PowerMac is selected.
