The function alloc_carmine_fb() references the variable __devinitdata
carminefb_fix. This is often because alloc_carmine_fb lacks a

Currently, it is possible to set a graphics VESA mode at boot time via the
vga= parameter even when no framebuffer driver supporting this is
configured. This could lead to the system booting with a black screen,
without a usable console.Fix this problem by only allowing to set graphics modes at boot time if a
supporting framebuffer driver is configured.Signed-off-by: Michal Januszewski

Some BIOSes return error codes when queried for information about
modes from their own modelist. uvesafb treats this as an error
case and bails out.Change this behavior so that broken modes do not prevent the driver
from working. Only the failure to retrieve information about any
usable video mode is considered to be an error case.Signed-off-by: Michal Januszewski

Implement support for HW color expansion of 1bpp images, along with some
improvements to the FIFO handling and other accel operations.The offset fixup code is now unnecessary as the fbcon core will call our
set_par upon switch back from KD_GRAPHICS before anything else happens. I
removed it as it would slow down accel operations.The fifo wait has been improved to avoid hitting the HW register as often,
and the various accel ops are now performing better caching of register
values.Overall, this improve accel performances. The imageblit acceleration does
result in a small overall regression in performances on some machines (on
the order of 5% on some x86), probably becaus the SW path provides a
better bus utilisation, but I decided to ingnore that as the performances
is still very good, and on the other hand, some machines such as some
sparc64 get a 3 fold performance improvement.Signed-off-by: Benjamin Herrenschmidt

A memory clock value (MCLK) is changed to a minimum required by a current
mode bandwidth. This usually lowers the MCLK to its minimum (50 MHz) thus
decreasing the card performance. Just leave the MCLK value set by card
BIOS.The CL-GD5446 Technical Reference Manual point 9.9.1.3 states that if a
pixclock value is close (~1%) to the MCLK or MCLK/2 this may result in a
jitter on the screen. A countermeasure is to use the MCLK as pixclock
source instead of a VCLK. The patch implements this as well.Signed-off-by: Krzysztof Helt

Add support for Intel's 945GME graphics chip to the intelfb driver. I
have assumed that the 945GME is identical to the already-supported 945GM
apart from its PCI IDs; this is based on a quick look at the X driver for
these chips which seems to treat them identically.The 945GME is used in the ASUS Eee 901, and I coded this in the hope that
I'd be able to use it to get a console at the native 1024x600 resolution
which is not known to the BIOS. I realised too late that the intelfb
driver does not support mode changing on laptops, so it won't be any
use for me.Signed-off-by: Phil Endecott
