Adds an extra layer of indirection to each register access, but it's not
too bad, and will also go away as pieces are ported.

These currently just call the existing ones in nouveau_drv.c, but will be
extended in upcoming commits. This needed to be separated from the current
code as there will be some header clashes until things are ported.

This commit provides most of the infrastructure to support a major overhaul
of Nouveau's internals coming in the following commits. This work aims to
take all the things we've learned over the last several years, and turn that
into a cleaner architecture that's more maintainable going forward.
RAMHT and MM bits of the new core have been left out for the moment, and
will be pulled in as I go through the process of porting the code to
become either subdev or engine modules.
There are several main goals I wanted to achieve through this work:
-- Reduce complexity
The goal here was to make each component of the driver as independent as
possible, which will ease maintainability and readability, and provide a
good base for resetting locked up GPU units in the future.
-- Better tracking of GPU units that are required at any given time
This is for future PM work, we'll be able to tell exactly what parts of the
GPU we need powered at any given point (etc).
-- Expose all available NVIDIA GPUs to the client
In order to support things such as multi-GPU channels, we want to be able
to expose all the NVIDIA GPUs to the client over a single file descriptor
so it can send a single push buffer to multiple GPUs.
-- Untangle the core hardware support code from the DRM implementation
This happened initially as an unexpected side-effect of developing the
initial core infrastructure in userspace, but it turned into a goal of
the whole project. Initial benefits will be the availablility of a
number of userspace tools and tests using the same code as the driver
itself, but will also be important as I look into some virtualisation
ideas.
v2: Ben Skeggs <bskeggs@redhat.com>
- fix duplicate assignments noticed by clang
- implement some forgotten yelling in error path
- ensure 64-bit engine mask is used everywhere
v3: Marcin Slusarz <marcin.slusarz@gmail.com>

v4: Ben Skeggs <bskeggs@redhat.com>

Future work will be headed in the way of separating the policy supplied by
the nouveau drm module from the mechanisms provided by the driver core.
There will be a couple of major classes (subdev, engine) of driver modules
that have clearly defined tasks, and the further directory structure change
is to reflect this.
No code changes here whatsoever, aside from fixing up a couple of include
file pathnames.

Won't necessarily be a drm_mm_node in the future, and I can't think of any
good reason to not use the offset from the bo struct. There may have been
some reason once apon a time, but, separate commit just in case.

Fixes some unfortunate races on resume. The G84 version of the code doesn't
need this as "gpuobj"s are automagically suspended/resumed by the core code
whereas pinned buffer objects are not.

Manual backmerge of -rc7 to resolve a silent conflict leading to
compile failure in drivers/gpu/drm/i915/intel_hdmi.c.
This is due to the bugfix in -rc7:
commit b98b60167279df3acac9422c3c9820d9ebbcf9fb
Author: Wang Xingchao <xingchao.wang@intel.com>
Date: Thu Sep 13 07:43:22 2012 +0800
drm/i915: HDMI - Clear Audio Enable bit for Hot Plug
Since this code moved around a lot in -next git put that snippet at
the wrong spot. I've tried to fix this by making the conflict explicit
by merging a version for next with:
commit 3cce574f0190dd149472059fb69267cf83d290f9
Author: Wang Xingchao <xingchao.wang@intel.com>
Date: Thu Sep 13 11:19:00 2012 +0800
drm/i915: HDMI - Clear Audio Enable bit for Hot Plug unconditionally
But that failed to solve the entire problem. To avoid pushing out
further -nightly branch to our QA where this is broken, do the
backmerge and manually add the stuff git adds to -next from the patch
in -fixes.
Note that this doesn't show up in git's merge diff (and hence is also
not handled by git rerere), which adds to the reasons why I'd like to
fix this with a verbose backmerge. The git merge diff only shows a
bunch of trivial conflicts of the "code changed in lines next to each
another" kind.

git://git.infradead.org/users/dhowells/linux-headers
Pull preparatory patches for user API disintegration from David Howells:
"The patches herein prepare for the extraction of the Userspace API
bits from the various header files named in the Kbuild files.
New subdirectories are created under either include/uapi/ or
arch/x/include/uapi/ that correspond to the subdirectory containing
that file under include/ or arch/x/include/.
The new subdirs under the uapi/ directory are populated with Kbuild
files that mostly do nothing at this time. Further patches will
disintegrate the headers in each original directory and fill in the
Kbuild files as they do it.
These patches also:
(1) fix up #inclusions of "foo.h" rather than <foo.h>.
(2) Remove some redundant #includes from the DRM code.
(3) Make the kernel build infrastructure handle Kbuild files both in
the old places and the new UAPI place that both specify headers
to be exported.
(4) Fix some kernel tools that #include kernel headers during their
build.
I have compile tested this with allyesconfig against x86_64,
allmodconfig against i386 and a scattering of additional defconfigs of
other arches. Prepared for main script

Remove redundant DRM UAPI header #inclusions from drivers/gpu/.
Remove redundant #inclusions of core DRM UAPI headers (drm.h, drm_mode.h and
drm_sarea.h). They are now #included via drmP.h and drm_crtc.h via a preceding
patch.
Without this patch and the patch to make include the UAPI headers from the core
headers, after the UAPI split, the DRM C sources cannot find these UAPI headers
because the DRM code relies on specific -I flags to make #include "..." work
on headers in include/drm/ - but that does not work after the UAPI split without
adding more -I flags.

Pull workqueue changes from Tejun Heo:
"This is workqueue updates for v3.7-rc1. A lot of activities this
round including considerable API and behavior cleanups.
* delayed_work combines a timer and a work item. The handling of the
timer part has always been a bit clunky leading to confusing
cancelation API with weird corner-case behaviors. delayed_work is
updated to use new IRQ safe timer and cancelation now works as
expected.
* Another deficiency of delayed_work was lack of the counterpart of
mod_timer() which led to cancel+queue combinations or open-coded
timer+work usages. mod_delayed_work[_on]() are added.
These two delayed_work changes make delayed_work provide interface
and behave like timer which is executed with process context.
* A work item could be executed concurrently on multiple CPUs, which
is rather unintuitive and made flush_work() behavior confusing and
half-broken under certain circumstances. This problem doesn't
exist for non-reentrant workqueues. While non-reentrancy check
isn't free, the overhead is incurred only when a work item bounces
across different CPUs and even in simulated pathological scenario
the overhead isn't too high.
All workqueues are made non-reentrant. This removes the
distinction between flush_[delayed_]work() and
flush_[delayed_]_work_sync(). The former is now as strong as the
latter and the specified work item is guaranteed to have finished
execution of any previous queueing on return.
* In addition to the various bug fixes, Lai redid and simplified CPU
hotplug handling significantly.
* Joonsoo introduced system_highpri_wq and used it during CPU
hotplug.
There are two merge commits - one to pull in IRQ safe timer from
tip/timers/core and the other to pull in CPU hotplug fixes from
wq/for-3.6-fixes as Lai's hotplug restructuring depended on them."
Fixed a number of trivial conflicts, but the more interesting conflicts
were silent ones where the deprecated interfaces had been used by new
code in the merge window, and thus didn't cause any real data conflicts.
Tejun pointed out a few of them, I fixed a couple more.

flush[_delayed]_work_sync() are now spurious. Mark them deprecated
and convert all users to flush[_delayed]_work().
If you're cc'd and wondering what's going on: Now all workqueues are
non-reentrant and the regular flushes guarantee that the work item is
not pending or running on any CPU on return, so there's no reason to
use the sync flushes at all and they're going away.
This patch doesn't make any functional difference.

PFIFO_INTR = 0x40000000 appears to be a normal case on nvc0/nve0 PFIFO,
the binary driver appears to completely ignore it in its PFIFO interrupt
handler and even masks off the bit (as we do) in PFIFO_INTR_EN at init
time.
The bits still light up in the hardware sometimes though, so lets just
ignore any bits we haven't explicitely requested.

NVIDIA do that at startup too on Fermi, so perhaps the heap of 0x10
intrs we receive are normal and we can ignore them.
On Kepler NVIDIA *don't* do this, but the hardware appears to come up
with the bit masked off by default - so that's probably why :)
This should silence some interrupt spam seen on Fermi+ boards.

This is required to fix an issue on the Retina MBP where the eDP panel's
AUX channel isn't wired up to the HPD pin for the panel, causing our aux
code to bail out early.
From looking at various traces of the binary driver, it appears NVIDIA do
something very similar on at least all nv50+ chipsets during their
initialisation sequence. So, hopefully this is safe.
Issue and fix initially tracked down by Ryan Bourgeois on fdo#51971.
Backported fix from reworked nouveau kernel module.

I have a very limited number of traces available for DP on NVD9+, but,
these values produce the same as the binary driver on a confirmed 18-bit
eDP panel and a confirmed 24-bit eDP panel (Retina MBP).
It's interesting that the bitfield values also match the MODE_CTRL values
that control the same thing on nv50:nvd9.

Ben says its just a single fix to avoid the wrong pcopy units being used.

On some Fermi chipsets (NVCE particularly) PCOPY1 doesn't exist. And if
what I've seen on Kepler is true of Fermi too, chipsets of the same type
can have different PCOPY units available.
This should fix a v3.5 regression reported by a number of people effecting
suspend/resume on NVC8/NVCE chipsets.

This callback is a no-op in nouveau, and the upcoming apple-gmux
switcheroo support won't require it either. Rather than forcing drivers
to stub it out, just make it optional and remove the callback from
nouveau.

This fix is a backport from the reworked nouveau driver. It masks off the
engines we're not expecting to use before attempting a channel kickoff.

The copy engine exhibits random memory corruption in at least one case, the
GeForce 320M (nv50, 0xaf) in the MacBookAir3,1.
This patch omits creating the engine for the specific chipset, falling back
to M2MF, which kills the symptoms.

At least partially fixes DP output detection on W530. Not sure if more
issues remain, or if my adaptor is just behaving weirdly (it does that
sometimes).
In any case, this patch is necessary.

Current name is misleading, because this error can be triggered by other
conditions, like changing STRMOUT parameter without disabling STRMOUT first.
