This populates the connectors with HPD (Hot Plug Detect)
information. This will be used in subsequent patches
for automatic digital monitor connect/disconnect handling.

This moves the radeon DP link training call to happen when we

This fix reorganises the initial DP link training slightly, and
actually makes DP work under kms here.

Not returning here caused us to get a display port version of 0 for everything
this caused power up to not get sent which ends up in a black screen.

Both radeon and nouveau can re-use this code so move it up a level
so they can. However the hw interfaces for aux ch are different
enough that the code to translate from mode, address, bytes
to actual hw interfaces isn't generic, so move that code into the
Intel driver.

This is intended to be used by ttm-aware drivers to
1) Block clients to inactive masters when
they try to validate buffers for GPU use.
2) Optionally block clients to the current master when
there is thrashing due to GPU memory shortage.
Used by the vmwgfx driver.

Add objects needed for user-space to maintain reference counts on ttm objects.
This is used by the vmwgfx driver which allows user-space to maintain

Again we try to put VRAM at 0, and it didn't work on this chipset,
reports of corrupt RAM appeared on irc and bugzilla.
Fix the vram location according to what the BIOS setup, I'm not 100%
sure we don't need the same thing on rs690/rs780/rs880, we probably
should do it there just in case as its what the DDX does.

This commit adds a ioctl and property to allow userspace
to notify the kernel that a framebuffer has changed. Instead
of snooping the command stream this allows finer grained
tracking of which areas have changed.
The primary user for this functionality is virtual hardware
like the vmware svga device, but also Xen hardware likes to
be notify. There is also real hardware like DisplayLink and
DisplayPort that might take advantage of this ioctl.

The vmwgfx driver has a per master rw lock around TTM, to guarantee
mutual exclusion when needed.
This is typically when all evictable buffers are evicted due to
1) vt switch
2) master switch
3) suspend / resume.
In the multi-master case, on master switch the new master takes the
previously active master lock in write mode, and then evicts all
buffers. Any clients to previous masters will then block on that lock
when trying to validate a buffer. fbdev also acts as a virtual master
wrt this.

The locking & protection of radeon object was somewhat messy.
This patch completely rework it to now use ttm reserve as a
protection for the radeon object structure member. It also
shrink down the various radeon object structure by removing
field which were redondant with the ttm information. Last it
converts few simple functions to inline which should with
performances.

We really don't need to process every irq that comes in, we only
really want to do SW irq processing when we are actually waiting for
a fence to pass. I'm not 100% sure this is race free esp on non-MSI systems
so it needs some testing.

This enables the use of interrupts on r6xx/r7xx hardware.
Interrupts are implemented via a ring buffer. The GPU adds
interrupts vectors to the ring and the host reads them off
in the interrupt handler. The interrupt controller requires
firmware like the CP. This firmware must be installed and
accessble to the firmware loader for interrupts to function.
MSIs don't seem to work on my RS780. They work fine on all
my discrete cards. I'm not sure about other RS780s or
RS880s. I've disabled MSIs on RS780 and RS880, but it would
probably be worth checking on some other systems.
v2 - fix some checkpatch.pl problems;
re-read the disp int status reg if we restart the ih;
v3 - remove the irq handler if r600_irq_init() fails;
remove spinlock in r600_ih_ring_fini();
move ih rb overflow check to r600_get_ih_wptr();
move irq ack to separate function;
