b6d57ae97a MIPS: gbe: Make needlessly global symbols static in drivers/video/gbefb.c
The following symbols are needlessly defined global:

default_mode
default_var
gbe_mem_phys
gbe_turn_off
gbefb_exit
gbefb_init
gbefb_setup

This error was noticed by namespacecheck when compiling ip32_defconfig.

This patch makes the symbols static.

ee1ef82c7e viafb: make it work on x86_64
Fix a bug in viafb on x86_64 builds (e.g. for VIA Nano CPU).

You cannot make the assumption that sizeof(unsigned int) ==
sizeof(unsigned long), so the parsing of the default mode (640x480) fails,
leading to a division by zero during insmod of the driver.

bdca0f9b1e fbdev: fix fillrect for 24bpp modes
The software fillrect routines do not work properly when the number of
pixels per machine word is not an integer.  To see that, run the following
command on a fbdev console with a 24bpp video mode, using a
non-accelerated driver such as (u)vesafb:

  reset ; echo -e '\e[41mtest\e[K'

The expected result is 'test' displayed on a line with red background.
Instead of that, 'test' has a red background, but the rest of the line
(rendered using fillrect()) contains a distored colorful pattern.

This patch fixes the problem by correctly computing rotation shifts.  It
has been tested in a 24bpp mode on 32- and 64-bit little-endian machines.

b175dc0928 vgacon: return the upper half of 512 character fonts
Uwe Geuder noted that he gets random bitmaps on a text console if he tried
to type extended characters (like the e acute).  For him everything above
unicode 0xa0 was corrupted.

After some digging there seems to be a little culprit in vgacon since the
beginning of ages (well git).  The function vgacon_font_get will store the
number of characters correctly in font->charcount but then calls to
vgacon_do_font_op(..., 0, 0).  Which means only the lower 256 characters
are actually stored to the fontdata.  The rest is left untouched.  So the
next time that saved data is used, the garbled font appears.  This happens
on every switch between text consoles.

c78a628849 backlight: Add support for MacBook 5, MacBook Air 2, and MacBook Pro 5
This patch adds support for the new Apple models incorporating an Nvidia
chipset.  Apple still uses the same protocol as on older models, but the
registers moved to a different address. To do this, two sets of functions
are added for the Intel/Nvidia chipset models and passed by the DMI_MATCH
function.

The initial code has been contributed by Hu Gang <hugang@soulinfo.com>.

The driver is known to work on MacBook Pro 3, MacBook Pro 4 and MacBook
Pro 5.

Its known to work with limitations on MacBook 5 / MacBook Air 2. Changing
brightness within X doesn't work, if using Nvidia's proprietary graphics
driver with no known fix at present. Changing brightness on a text console
or using the open-source driver does work.

MacBook Pro 5 has a known bug where the initial brightness after bootup is
the last recently used brightness (in Mac OSX), while the firmware reports
maximum. Impossible to fix.

e14a685dfa efifb: dmi set video type
The current logic for dmi matching in efifb does not allow efifb to load
on all hardware that we can dmi match for.

For a real world example, boot with elilo (3.7 or 3.8 vanilla) and on a
Apple (MacBook) and EFI framebuffer driver will not load (you will have no
video).  This specific hardware is efi v1.10, so we have UGA and not GOP.
Without special bootloader magic (i.e.  extra elilo patches for UGA
graphics detection) no screen info will be passed to the kernel and as a
result efifb will not load.

This patch allows the dmi match to happen by moving it to earlier in
efifb_init, and sets the video type (in set_system) so that efifb can load
when we have a valid dmi match and already know the specifics of the
hardware.

Without this patch the efifb driver will fail to load in the event screen
info is not found and passed in by the bootloader, being that we will
never get to look for a dmi match.  A primary reason for matching with dmi
is because not all bootloaders detect the video info properly.  The
solution is that in the event of a dmi match, we should set
screen_info.orig_video_isVGA.  Most bootloaders fail to set screen info on
Apple hardware, and this is a big problem for people who use Apple
hardware.

Tested on a MacBook SantaRosa with elilo-3.8 (vanilla) and resolves the
issue, the dmi match now works, EFI framebuffer now loads and video works.

04645fc337 tridentfb: delete acceleration Kconfig option
Remove Kconfig option for tridentfb acceleration.  The acceleration can be
switched off with modules "noaccel" parameter.

The acceleration for Trident chips was fixed in the 2.6.27 kernel.

Also, add CyberXXX and CyberBlade names to Kconfig option's name.  It should
make easier to find the tridentfb choice for cyblafb driver's users.  The
cyblafb driver has been replaced by the tridentfb driver.

84d9077b33 fb: hide hardware cursor in graphics mode (Mach64)
A hardware cursor is left enabled in the fb_set_par() which is called when a
new console is created.  This is inconsistent with software cursor's
behaviour.

Also, this makes a hardware cursor always visible in the Xfbdev (Xorg kdrive)
server.

23b7365454 uvesafb: fix selecting mode with the vbemode option
If the vbemode option is used, uvesafb calls fb_get_mode() without first
setting the resolution in info->var.  This results in a division by zero
in fb_get_mode(), as evidenced e.g.  in [1].  Fix this by ensuring the
info->var structure is populated before fb_get_mode() is called.

ddb53d48da fbdev: remove cyblafb driver
A tridentfb driver has all the functionality of the cyblafb driver without
the bugs of the latter.

Changes to the tridentfb driver:

- FBINFO_READS_FAST added to the tridentfb.  The cyblafb used a blitter
  for scrolling which is faster than color expansion on Cyberblade
  chipsets.  The blitter is slower on a discrete Blade3D core.  Use the
  blitter for scrolling in the tridentfb only for integrated Blade3D
  cores.  Now, scrolling speed is about equal for the tridentfb and the
  cyblafb.

- a copyright notice addition is done on request of Jani Monoses (the
  first author of the tridentfb).

Tested on AGP Blade3D card and PCChips
M787CLR motherboard: VIA C3 cpu +
VT8601 north  bridge (aka Cyberblade/i1).
