The DCB table provided by the VBIOS on most MXM chips has a number of
entries which either need to be disabled, or modified according to the
MXM-SIS Output Device Descriptors.
The x86 vbios code usually takes care of this for us, however, with the
large number of laptops now with switchable graphics or optimus, a lot
of the time nouveau is responsible for POSTing the card instead - leaving
some fun situations like, plugging in a monitor and having nouveau decide
3 connectors actually just got plugged in..
No MXM-SIS fetching methods implemented yet.

Otherwice code that responsible for idling the card can't work.
BIOS init tables are supposed to init the clocks to correct values,
so that shouldn't cause any problems (we don't reclock by default anyway)

Subject: [PATCH] drm: Make the per-driver file_operations struct const
The DRM layer keeps a copy of struct file_operations inside its
big driver struct... which prevents it from being consistent and static.
For consistency (and the general security objective of having such things
static), it's desirable to get this fixed.
This patch splits out the file_operations field to its own struct,
which is then "static const", and just stick a pointer to this into
the driver struct, making it more consistent with how the rest of the
kernel does this.

It may not be necessary to fail in certain cases (such as failing to idle)
on module unload, whereas on suspend it's important to ensure a consistent

The ability to use NVIDIA's fuc has been retained *temporarily* in order
to better debug any issues that may be lingering in our initial attempt
at writing this ucode. Once I'm fairly confident we're okay, it'll be
removed.
There's a number of things not implemented by this fuc currently, but
most of it is sets of state that our context setup would not have used
anyway. No doubt we'll find out what they're for at some point, and
implement it if required.
This has been tested on 0xc0/0xc4 thus far, and from what I could tell
it worked as well as NVIDIA's. It's also been tested on 0xc1, but even
with NVIDIA's fuc that chipset doesn't work correctly with nouveau yet.
0xc3/0xc8/0xce should in theory be supported too, but I don't have the
hardware to check that.
There's no doubt numerous bugs to squash yet, please report any!

There's lots of more-or-less independant engines present on NVIDIA GPUs
these days, and we generally want to perform the same operations on them.
Implementing new ones requires hooking into lots of different places,
the aim of this work is to make this simpler and cleaner.

The -rt patches change the console_semaphore to console_mutex. As a
result, a quite large chunk of the patches changes all
acquire/release_console_sem() to acquire/release_console_mutex()
This commit makes things use more neutral function names which dont make
implications about the underlying lock.
The only real change is the return value of console_trylock which is
inverted from try_acquire_console_sem()
This patch also paves the way to switching console_sem from a semaphore to
a mutex.

nouveau_fence_* functions are not type safe, which could lead to bugs.
Additionally every use of nouveau_fence_unref had to cast struct
nouveau_fence to void **.
Fix it by renaming old functions and creating static inline functions with
new prototypes. We still need old functions, because we pass function
pointers to ttm.
As we are wrapping functions, drop unused "void *arg" parameter where possible.

Only supported on NV50+ so far, and disabled by default currently. The
module parameter "msi=1" will enable it.
There's a kernel bug which will cause this to fail if the module (or the
NVIDIA binary driver) has ever been loaded before loading nouveau with
MSI enabled. As such, this is only safe to enable if you have nouveau
load on boot, and don't wish to ever reload it.
The workaround is to "echo 0 > /sys/bus/pci/devices/<device>/enable"
until the enable count reads 0. Then you should be able to load nouveau
with MSI enabled.

The drm device drivers currently allow seeking on the
character device but never care about the actual
file position.
When we change the default llseek operation to be
no_llseek, calling llseek on a drm device would
return an error condition, which is an API change.
Explicitly setting noop_llseek lets us keep the
current API.

BIOS scripts usually make an attempt to reset the AGP controller,
however on some nv4x cards doing it properly involves switching FW off
and on: if we do that without updating the AGP bridge settings
accordingly (e.g. with the corresponding calls to agp_enable()) we
will be locking ourselves out of the card MMIO space. Do it from
nouveau_mem_reset_agp() before the init scripts are executed.
