As Chris mentioned there is a tendency for us to find out more
PCI IDs only when users report. So let's add all new reserved Haswell IDs.
I didn't have better names for this reserved ids and didn't want to use rsvd1
and rsvd2 groups, so I decided to use "B" and "E" that stands for the last
id digit.

When publishing first HSW ids we weren't allowed to use "GT3" codname.
But this is the correct codname and Mesa is using it already.
So to avoid people getting confused why in Mesa it is called GT3 and here
it is called GT2_PLUS let's fix this name in a standard and correct way.

There is a tendency for a product to ship based on a 'reserved' PCI-ID
prior to us being notified about it. In other words, the first we find
out about such a product is when customers start complaining about their
shiny new hardware not being supported...

Do not rely on a fully populated set of CRTCs, but merely note that the
GETRESOURCES ioctl returns an error if KMS is not enabled.

If the kernel has the module, but the KMS module option is not enabled,
we cannot function. So after checking to see if the i915.ko is bound,
then querying whether it provides any KMS resources. If it has no CRTCs
attached, then we need to failover to the VESA/fbdev drivers. Note that
this should have been detected by drmCheckModesettingSupported()

Once upon a time this was used to hide a compiler warning about a
pointer mismatch, now the compiler still warns about the cast, making
the indirect moot.

Allow --enable-ums-only as a counter-option to --enable-kms-only in case
the distribution wishes to enable a non-root KMS driver but also offer
a separate UMS driver for i81x.
On the second pass, use "--enable-ums-only --disable-uxa --disable-sna"
to get the trimmed down unaccelerated i810 support.

Section "Device"
Option "AccelMethod" "uxa/glamor/sna"
EndSection
The appropriate backend must also be enabled at compile time for the
runtime option to be available (i.e. --enable-uxa (default) --enable-sna
--enable-glamor)

Y-tiling is slightly faster with RENDER operations, so attempt to
allocate source-only pixmaps using this tiling mode. Actually using
Y-tiling is a delicate balance because it then prevents the use of the
BLT. For instance, enabling Y-tiling by default gives a 30% performance
improvement on the fish-demo (compositing benchmark) at 2560x1440 on
Ironlake but regresses tiger-demo by 2x (spans benchmark).
So experiment with this compromise and allow for changing the default
tiling.
