This adds the initial i915 superioctl interface. The interface should be
sufficent even if the implementation may needs fixes/optimisations internally
in the drm wrt caching etc.

On the plus side, it was at least binary compatible.

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.
This mod makes the SAREA track plane to pipe mappings and corrects the name of
the plane info variables (they were mislabeled as pipe info since until now all
code assumed a direct mapping between planes and pipes).
It also updates the flip ioctl argument to take a set of planes rather than
pipes, since planes are flipped while pipes generate vblank events.
The data is now in kernel space, copied in/out as appropriate according to the
This results in DRM_COPY_{TO,FROM}_USER going away, and error paths to deal
with those failures. This also means that XFree86 4.2.0 support for i810 DRM
is lost.
As a fallout, replace filp storage with file_priv storage for "unique
identifier of a client" all over the DRM. There is a 1:1 mapping, so this
should be a noop. This could be a minor performance improvement, as everything
on Linux dereferenced filp to get file_priv anyway, while only the mmap ioctls
went the other direction.
This was used to make all ioctl handlers return -errno on linux and errno on
*BSD. Instead, just return -errno in shared code, and flip sign on return from
shared code to *BSD code.
These require that the status page be referenced by a pointer in GTT, rather
than phsyical memory. So, we have the X Server allocate that memory and tell
us the address, instead.
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.
i915_driver_irq_postinstall was forcing vblank interrupts to pipe A when
called with vblank interrupts disabled. This caused vblank interrupts to be
accidentally re-enabled when VT switching the X server. Instead, start the
driver with vblank interrupts enabled on pipe A to support older X servers,
but then leave control over the state to the X server if it is able to do so.
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
The MI_WAIT_FOR_EVENT instruction does not support waiting for several events
at once, so this should fix the lockups with page flipping when both pipes are
enabled.
