We've talked about doing this since the start of the project, putting it off
until "some convenient time". Just after removing a third of the driver seems
like a convenient time, when backporting's probably not happening much anyway.

Add LVDS backlight and power VBT structures and dump from the BIOS reader.

The size of general definition block varies on different platform/machines.
In such case the number of child device is also different.
And it will be better to get the number of child device in general definition
block dynamically.
The number of child device can be calculated by the following formula:
(block_size - block_header_size) /
sizeof( struct child_device_config)

ALL_LVDS is actually not defined before and include GM45.
Embedded DP bit will be used for newer chips.

The server's pci_device structure ends up conflicting with libpciaccess's.
Just don't include the server structure for this non-server tool.
|
|
Document a few more VBT structures and comment on VBIOS communication a
bit. There should be enough there now for a sufficiently motivated
developer to start implementing support for hotkeys and other features
on pre-IGD OpRegion machines.
|
|
Still need to actually print all the flags & test on various platforms, but at
least the bits are documented now.
|
|
We just use the structure definitions now.
|
|
More correct & consistent with other definitions.

Issue found by Peter Clifton.
|
|
Make VBT parsing happen at driver init time rather than in each output init
function, to save time and better separate VBIOS code into i830_bios.[ch]. The
changes end up touching the output files due to field name changes, and allow
us to reorder & simplify our LFP mode detection code.
|
|
Improve the VBIOS feature detection and use it to find whether the platform
supports spread spectrum clocking. Use the specified reference clock, but
disable SSC if multiple heads are active, since it can cause problems in cloned
configurations.

Needed for new uint* usage.
|
|
Several uses are actually left, which are determined by the X Server
interfaces we're implementing.

Add-in modules have per-module data in the BIOS which contains configuration
information which cannot be entirely discovered.
|
|
These two sources are placed in higher priority to the BIOS data when
available, since the BIOS data has proven unreliable. The BIOS data is still
read, and warnings printed if it doesn't match what we probe. The BIOS data
remains useful for the situation where we want to turn on LVDS but there is no
EDID available and no current mode programmed (i.e. booting with VGA or TV
connected).
