The problem boils down to the order when the bit11
of the texture size is or'ed to the original width.
In the end each mipmap level has the same width or
height because of that 11 bit is ored to the scaled
down lod with and thus blows up the size again to the
full size or more due to the power of two rounding
afterwards.

The attached patch changes this order so that the
texture sizes are computed correct. Also the on error
the yet missing inputs to the size computation are
printed which helped me to find out where it really breaks.

Sometimes we will get the incorrect display modeline when parsing the detailed
timing in EDID. For example:
   >hsync/vsync width is zero
   >sync is beyond the blank.

So add the basic check for the detailed timing in EDID to avoid the incorrect
display modeline.

While investigating the cause of CRTC FIFO underruns, I noticed that when
converting the memory bandwidth calculation from the userspace X driver code,
an instance of '8.0' was apparently accidentally converted to '80'.
Signed-off-by: NMichel Dänzer <daenzer@vmware.com>
Signed-off-by: NDave Airlie <airlied@redhat.com>

The hook may change the number of bytes per pixel being scanned out, which
affects the CRTC memory bandwidth requirements. E.g. booting in 8bpp and then
running X in 32bpp would result in the bandwidth requirements being
underestimated for the latter and consequently in CRTC FIFO underruns causing
visible artifacts with 3D intensive workloads.

When GPU acceleration is not working with AGP try to fallback to non
AGP GART (either PCI or PCIE GART). This should make KMS failure on
AGP less painfull. We still need to find out what is wrong when AGP
fails but at least user have a lot of more chances to get a working
configuration with acceleration. This patch also cleanup R600/RV770
fallback path so they use same code as others asics. Version 2
factorize agp disabling logic to avoid code duplication and bugs.

The previous patches had some unwanted side effects, I've fixed
the lack of 32bpp working, and fixed up 16bpp so it should also work.

this also adds the interface to allow the driver to set a preferred
console depth so for example low memory rn50 can set it to 8bpp.
It also catches 24bpp on cards that can't do it and forces 32bpp.
