This allows multiple X server to use DRI and makes it possible to run
multiple X servers under KMS. This requires a 2.6.29 kernel to work.
On older kernels it will just log a warning and DRI will fail to
initialize for the second X server.
This is based on Jesse's origin patch for bug #12763.
But export integer range to user instead of hardware float
point format, and fix different real format on 965G and 945G
for contrast and saturation.
This can let user override non-stable driver TV load detect,
and set connector type manually, e.g for s-video to component
converter, this patch seems must needed to use HD modes.
This is to fix bug #16566, change TV format will cause BadMatch
error when crtc config apply. Everytime when we change TV format,
we may generate a new list of modelines as TV clock changed. After
randr get info request, new modelines will be probed and randr output's
modes will be renewed too. But crtc's mode failed to be updated,
as it never can find a matching mode now within new modes list.
So get info will return an invalid crtc's mode, later set crtc
config will pass that info, and xserver catches a bad match.
This patch trys to refresh output modes and setup crtc's mode
with new modelines in TV format change. So get info would be
sure to turn valid crtc mode that reference in current new modelines.
This is the intel video driver patch for a new chip, which is G33-like
and has some clocking setting related register changes. This patch adds
the pci id and DPLx/FPx register changes.
The gtt tool should just work to me, as the chip hasn't any changes
against G33 on this side.

The LVDS config bits in VBT driver feature block is used by vendor
to identify the board implement of integrated LVDS/eDP or SDVO LVDS.
And video bios uses these bits for LVDS enabling or not. So check
these bits for integrated LVDS might eliminate more quirks.
Instead of set control bus switch before every i2c start,
just set once before doing DDC. This should eliminate some
encoders returning error during that.
As SDVO TV uses SDVO_TVClkIn from SDVO encoder for clock reference,
it needs to generate proper PLL for current input clock. This uses
fixed PLL table from vbios for this. And possible sdvo mulitiplier
has to be setup correctly. This makes TV output stable on my 945GCLF2
board with NTSC-M format.
SDVO HDMI encode and audio is not setup in detect,
which fails in hotplug case for HDMI audio. Fix to
check current encode type and set flag for HDMI audio
enabling.
Check and set HDMI encode state in get_modes.
