Add code to get panel modes from the VBIOS if present and check whether certain
outputs exist. Should make our display detection code a little more robust.
It would be nice if one day the DRM driver was the canonical source for
register definitions and core macros. To that end, this patch cleans
things up quite a bit, removing redundant definitions (some with
different names referring to the same register) and generally tidying up
the header file.
This change adds a driver feature that for i915 is controlled by a module
parameter. You now need to do insmod i915.ko modeset=1 to enable it the
modesetting paths.
It also fixes up lots of X paths. I can run my new DDX driver on this code
with and without modesetting enabled
On many chipsets, the checks for DPLL enable or VGA mode will prevent the
pipeconf regs from being restored, which could result in a blank display or X
failing to come back after resume. So restore them unconditionally along with
actually restoring pipe B's palette correctly.
On resume, if the interrupt state isn't restored correctly, we may end
up with a flood of unexpected or ill-timed interrupts, which could cause
the kernel to disable the interrupt or vblank events to happen at the
wrong time. So save/restore them properly.
In hibernate, we may end up calling the VGA save regs function twice, so we
need to make sure it's idempotent. That means leaving ARX in index mode after
the first save operation. Fixes hibernate on 965.
Flags pending validation were stored in a misleadingly named field, 'mask'.
As 'mask' is already used to indicate pieces of a flags field which are
changing, it seems better to use a name reflecting the actual purpose of
this field. I chose 'proposed_flags' as they may not actually end up in
'flags', and in an case will be modified when they are moved over.
This affects the API, but not ABI of the user-mode interface.

Merge in the latest master bits and update the remaining drivers (except
mach64 which math_b is working on). Also remove the 9xx hack from the i915
driver; it seems to be correct.
Add suspend/resume support to the i915 driver. Moves some of the
initialization into the driver load routine, and fixes up places where we
assumed no dev_private existed in some of the cleanup paths. This allows
us to suspend/resume properly even if X isn't running.

Mostly removing typedefs that snuck into the modesetting code and
updating to the latest TTM APIs. As of today, the i915 driver builds,
but there are likely to be problems, so debugging and bugfixes will
come next.
If the driver doesn't support vertical blank interrupts, it won't call
drm_vblank_init(), and dev->num_crtcs will be 0.
Also fix an off-by-one test against dev->num_crtcs.
places).
Add new FB hooks to the drm driver structure and make i915 use them for an
Intel specific FB driver. This will allow acceleration and better handling
of the command stream.
When the kernel driver is loaded it sets up a lot of stuff..
it tears down the same stuff on unload.
This add a new map type called DRM_DRIVER which means the driver will clean the mapping up
and fix up the map cleaner
