The current init code sets hiprilvl to 0 and maxhipri to 5. According to the
specs those values are illegal on both G200 and G400. It also causes
distortions on the TV-out at least when CRTC2 is in YUV mode as is the case
with DirectFB. This patch resets both values to 0.

Add new entries for Mystique AGP with the PCI ID 0x051e.
I don't actually have such boards but according to google they do exist.
Curiosly X.Org doesn't recognize that PCI ID. And what's even more
interesting is that Matrox's own Windows drivers don't recognize it either.
After going through about a dozen different versions I did find one older
driver that does list this particular ID. It is also listed in the pci.ids
file.
I'm not sure if non-220 AGP chips exist. I left the chip revision check
intact for AGP chips nonetheless.

Currently the fb_find_nearest_mode() function finds a mode with screen
resolution closest to that described by the 'var' argument and with some
arbitrary refresh rate (eg. in the following sequence of refresh rates: 70 60
53 85 75, 53 is selected).
This patch fixes the function so that it looks for the closest mode as far as
both resolution and refresh rate are concerned. The function's first argument
is changed to fb_videomode so that the refresh rate can be specified by the
caller, as fb_var_screeninfo doesn't have any fields that could directly hold
this data.

Reported by: Jean-Philippe Guérard (Bugzilla Bug 1782)
"I've tried with video=atyfb:debug and video=atyfb:debug,mode:1280x600, \
nomtrr.
In both case, the screen stays black, but seems divided into 4 vertical bands.
Some white lines pop up randomly on each vertical band."
The problem is a combination of an incorrect xclk plus lack of timing
information. The adapter is attached to an LCD device that can do 1280x600
(which is not a standard resolution). The global mode database does not have
an entry for it. Fortunately, the Video BIOS contains the complete timing
info for this display, however, atyfb is not making use of it.
Add support to get the timing information from the BIOS, if available.

hardware, it's possible that the driver's fb_release() method will attempt to

According to Jon Smirl, filling in the field fb_cursor with soft_cursor for
drivers that do not support hardware cursors is redundant. The soft_cursor
function is usable by all drivers because it is just a wrapper around
fb_imageblit. And because soft_cursor is an fbcon-specific hook, the file is
moved to the console directory.
Thus, drivers that do not support hardware cursors can leave the fb_cursor
field blank. For drivers that do, they can fill up this field with their own
version.
The end result is a smaller code size. And if the framebuffer console is not
loaded, module/kernel size is also reduced because the soft_cursor module will
also not be loaded.

nvidiafb didn't fully hook-up the code it borrowed from X for doing flat
panel dithering (this is useful for 6 bits panels). This adds a driver
option to force it, and by default "reads" the current value from the chip
to get the firmware setting. It significantly improves the quality of
images on the iMac G5 I have here (though the X driver doesn't yet "read"
the current value and defaults to 0, so you have to add Option "FBDither"
"true" to your X config file to get that, I'll try to fix X.org to "read"
the default unless specified asap).

Some visually impaired people use hardware devices which directly read
the vga screen. When newt for instance asks to hide the cursor for
better visual aspect, the kernel puts the vga cursor out of the screen,
so that the cursor position can't be read by the hardware device. This
is a great loss for such people.
Here is a patch which uses the same technique as CUR_NONE for hiding the
cursor while still moving it.

This patch fixes a long-standing vgacon bug: characters with the bright bit
set were left on the screen and not blacked out. All I did was that I
lookuped up some examples on the net about setting the vga palette, and
added the call missing from the linux kernel, but included in all other
ones. It works for me.
You can test this by writing something with the bright set to the
console, for example:
echo -e "\e[1;31mhello there\e[0m"
and then wait for the console to blank itself (by default, after 10 mins
of inactivity), maybe making it faster using
setterm -blank 1
so you only have to wait 1 minute.

Change the phys_mem_access_prot() function to take a pfn instead of an
address. This allows mmap64() to work on /dev/mem for addresses above 4G
on 32-bit architectures. We start with a pfn in mmap_mem(), so there's no
need to convert to an address; in fact, it's actively bad, since the
conversion can overflow when the address is above 4G.
Similarly fix the ppc32 page_is_ram() function to avoid a conversion to an
address by directly comparing to max_pfn. Working with max_pfn instead of
high_memory fixes page_is_ram() to give the right answer for highmem pages.
