Now that mesa 9.2 is out with support for tiling
on SI asics, we can enable it here. Tiling improves
memory bandwidth utilization.
V2: update man page

This necessarily involved adding some content, which I was able to
Google for. Please review, correct, and make more specific.
Bodiless .TP entries screw up doclifter's page parsing. Please
don't do that anymore.
Defaults to shadowfb. 3D acceleration is available with glamor. 2D
acceleration is disabled until the radeonsi driver can handle glamor's
shaders.

Enable at build time with --enable-glamor and runtime with
Option "AccelMethod" "glamor"
The most notable lack of functionality is XVideo. Use something like VDPAU for
now.

A new optional kms driver option "SwapbuffersWait" is defined
for xorg.conf, which defaults to "on". If "on", DRI2 bufferswaps
will be synchronized to vsync, otherwise not.
This currently only affects copy-swaps, not pageflipped swaps.
It also requires a swap_interval setting of zero by the OpenGL
client.
Ideally, we'd provide a way for dri2 to pass the current swap
interval to the ddx so we could change this dynamically.

- makes Xv more consistent with r1xx/r2xx/r6xx/r7xx
- Xv attributes like brightness, contrast, hue, etc. only work
when bicubic is disabled.
- avoids performance issues on some systems when sampling from textures
in GART with kms.
- It can be re-enabled with using xvattr

Now that the screen section mapping is fixed,
Make the option per-instance and allow multiple
outputs to be specified; e.g., DVI-0 and HDMI-0
associated with instance 0 and LVDS and VGA-0
associated with instance 1.
Allows users that want to use zaphod mode to select
which xrandr outputs are assigned to which head. E.g.,
Option "ZaphodHeads" "LVDS,VGA-0"
will assign LVDS to the first zaphod driver instance
and VGA-0 to the second instance.
This patch returns NULL for pixmap creation when we are using
mixed pixmaps and the pixmap has a size.
The size check is necessary for the front buffer.
We add a flag to force pixmap creation for certain pixmaps
that need to be hw, like the DRI2 and Xv ones.
Idea from Michel and workarounds from Ben Skeggs.
v2: add Option "EXALowVRAM" to allow configuring this, value in MBs.

This attribute allows the user to override which
crtc is synced with when XV_VSYNC is enabled. This
is useful for clone modes where the user can might want
to override the default.
Allows you to specify an edid per output from a file
to override what is detected by DDC. Useful for
problematic monitors or KVM switches that block
DDC. Specifying an EDID that is not compatible with
your monitor could damage your monitor so use with
caution.
agd5f: cache the custom edid at startup so we don't
have to read it from file every time the output is
queried.
