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.

Some systems have multiple connectors connected to the same encoder;

separately which results in it trying to source the same encoder to
different crtcs. If we have an HDMI and DVI-D port on the same encoder,
pick the one to be considered connected based on the edid (HDMI if edid

When we are evicting from VRAM->RAM we allocate the ttm object,
but we don't set the caching policy on it before blitting into it.
This means on AGP we end up blitting into cached pages, and
the CPU later flushes out on top of them. This was mostly seen as
font corruption.
The other question is why we don't evict VRAM->GTT in a lot of cases,
this would save us some cache transitions since a lot of objects
that are evicted from VRAM will probably end up being pulled back in
a few operations later, and evicting them to system memory involves
2 unnecessary cache transitions.

New init path allow to simply asic initialization and make easier
to trace what happen on each different asic. We are removing most
callback. More cleanup should happen latter to remove even more
callback. Also cleanup register specific to R100,RV200,RV250.
Version 2 correct the placement on IGP of the VRAM inside GPU address
space to match the stollen RAM placement of IGP.

Also cleanup register specific to RS400/RS480. This patch also fix
legacy VGA register used to disable VGA access we were programming
wrong register. Now we should properly disable VGA on r100 up to
rs400 asics. Note that RS400/RS480 resume is broken, it hangs the
computer while reprogramming dynamic clock, doesn't work either
without that patch. We need to spend more time investigating this
issue. Version 2 of the patch remove dead code that was left
commented out in the previous version. Version 3 correct the
placement on IGP of the VRAM inside GPU address space to match the
stollen RAM placement of IGP.

Convert the r520 asic support to new init path, change are smaller than
previous one as most of the architecture is now in place and more code

[note this requires an fb patch posted to linux-fbdev-devel already]
This uses the normal video= command line option to control the kms
output setup at boot time. It is used to override the autodetection
done by kms.
video= normally takes a framebuffer as the first parameter, in kms
it will take a connector name, DVI-I-1, or LVDS-1 etc. If no output
connector is specified the mode string will apply to all connectors.
The mode specification used will match down the probed modes, and if
no mode is found it will add a CVT mode that matches.
video=1024x768 - all connectors match a 1024x768 mode or add a CVT on
video=VGA-1:1024x768, VGA-1 connector gets mode only.
The same strings as used in current fb modedb.c are used, except I've
added three more letters, e, D, d, e = enable, D = enable Digital,
d = disable, which allow a connector to be forced into a certain state.

This avoids needing to do a kmalloc > PAGE_SIZE for the main
indirect buffer chunk, it adds an accessor for all reads from
the chunk and caches a single page at a time for subsequent
reads.
changes since v1:
Use a two page pool which should be the most common case
a single packet spanning > PAGE_SIZE will be hit, but I'm
having trouble seeing anywhere we currently generate anything like that.
hopefully proper short page copying at end
added parser_error flag to set deep errors instead of having to test
every ib value fetch.
fixed bug in patch that went to list.

VGA arb requires DRM support for non-kms drivers, to turn on/off
irqs when disabling the mem/io regions.
VGA arb requires KMS support for GPUs where we can turn off VGA
decoding. Currently we know how to do this for intel and radeon
kms drivers, which allows them to be removed from the arbiter.

Before we use any of VRAM, we need to disable the VGA rendering
engine, this render text mode into a graphical framebuffer
for scanout, however it does this on vblank, and can end up
overwriting the GART table and r600 shader objects.

Someone on IRC reported problems after commit
95a8f1bf4f ('drm/radeon/kms: Move
radeon_clocks_init() call back after getting VRAM info.'). And indeed, at least
some ASIC vram_info hooks use the clock info obtained by
radeon_get_clock_info(). So, move that call out of radeon_clocks_init(), ahead
of the radeon_vram_info() call.
