Use GEM for ring buffer setup and framebuffer allocation. This means reworking
the hardware status page stuff a bit (just use the basic range allocator for
vram for now) and #ifdef'ing out the TTM & DRI2 code. Works well enough to
load/unload several times and display fbcon on my T61 (though there's still
some unexplained console corruption).
Okay we have crtc, encoder and connectors.
No more outputs exposed beyond driver internals
I've broken intel tv connector stuff.
Really for TV we should have one TV connector, with a sub property for the
type of signal been driven over it
Use subclassing from the drivers to allocate the objects. This saves
two objects being allocated for each crtc/output and generally makes
exit paths cleaner.
This splits a lot of the core modesetting code out into a file of
helper functions, that are only called from themselves and/or the driver.
The driver gets called into more often or can call these functions from itself
if it is a helper using driver.
I've broken framebuffer resize doing this but I didn't like the API for that
in any case.
drm_crtc->fb may point to NULL, f.e X server will allocate a new fb
and assign it to the CRTC at startup, when X server exits, it will destroy
the allocated fb, making drm_crtc->fb points to NULL.
TV out needs to do load detection, which means we have to find an
available pipe to use for the detection. Port over the pipe reservation
code for this purpose.
This patch ties outputs, output properties and hotplug events into the
DRM core. Each output has a corresponding directory under the primary
DRM device (usually card0) containing dpms, edid, modes, and connection
status files.
New hotplug change events occur when outputs are added or hotplug events
are detected.

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.

Lots of changes to merge with alanh's latest stuff:
o fix use of fb->pitch now that it has the right value
o add new helper for finding the CRTC given an FB
o fix new fb_probe/fb_remove functions to take a CRTC
o fixup callers of new FB routines
o port drm_fb changes to intel_fb
o check for errors after creating fb buffer object
o go back to using cfb_imageblit since the accel stubs aren't ready
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.
Change from DIRECTCOLOR to TRUECOLOR, and enable
support for PSEUDOCOLOR. DIRECTCOLOR support needs more work.
Add the ability to change the mode on the fbdev device.
Support depth 8, 15, 16 and 24 (and 32).
Add a /dev/fbX device per CRTC, but there's some code which
doesn't allocate the fbX device unless the output is actually
enabled. Read the code on this as it impacts the fbcon map flags.
Pick CRTC's based on the available outputs. More work could
be done here to match modes, so cloning could be achieved on
outputs. This fits more inline with what the X code does.
- move EDID structures to drm_edid.h
- add EDID info structure to drm_output
- add a few routines to intel_display for getting current mode info
- add some prototypes to intel_drv.h and drm_crtc.h
