47a1e0fe4b drm/nvd0/dmaobj: initial bind() method implementation
Currently unused, and rudimentary.  Lots to figure out here still, but
this is sufficient for what disp will need.

6c1689a08c drm/nouveau/dmaobj: move parent class check to bind() method
Otherwise when nvc0- gains a bind() method (disp needs it), the fifo
engine will attempt to create a dma object for the push buffer, which
is unnecessary on fermi.

The only sane place to put these checks is in the bind method itself,
and have it unconditionally called from wherever it might be needed.

3bb076af2a drm/nouveau/bios: fix DCB v1.5 parsing
memcmp->nv_strncmp conversion, in addition to name change, should have
inverted the return value.

But nv_strncmp does not act like strncmp - it does not check for string
terminator, returns true/false instead of -1/0/1 and has different
parameters order.

Let's rename it to nv_memcmp and let it act like memcmp.

eed6187d9f drm/nouveau/pm: do not stop reclocking if failing to set the fan speed
With the introduction of fan management modes, fan may not be drivable.
We should allow reclocking nonetheless.

This return was stupid to begin with since it may have left the card
in an intermediate state (clocks corresponding to a perflvl and voltage
corresponding to another one). The reclocking code will need to be
rewritten in a near-future in order to provide a better error handling.

612a9aab56 Merge branch 'drm-next' of git://people.freedesktop.org/~airlied/linux
Pull drm merge (part 1) from Dave Airlie:
 "So first of all my tree and uapi stuff has a conflict mess, its my
  fault as the nouveau stuff didn't hit -next as were trying to rebase
  regressions out of it before we merged.

  Highlights:
   - SH mobile modesetting driver and associated helpers
   - some DRM core documentation
   - i915 modesetting rework, haswell hdmi, haswell and vlv fixes, write
     combined pte writing, ilk rc6 support,
   - nouveau: major driver rework into a hw core driver, makes features
     like SLI a lot saner to implement,
   - psb: add eDP/DP support for Cedarview
   - radeon: 2 layer page tables, async VM pte updates, better PLL
     selection for > 2 screens, better ACPI interactions

  The rest is general grab bag of fixes.

  So why part 1? well I have the exynos pull req which came in a bit
  late but was waiting for me to do something they shouldn't have and it
  looks fairly safe, and David Howells has some more header cleanups
  he'd like me to pull, that seem like a good idea, but I'd like to get
  this merge out of the way so -next dosen't get blocked."

Tons of conflicts mostly due to silly include line changes, but mostly
mindless.  A few other small semantic conflicts too, noted from Dave's
pre-merged branch.

Merge tag 'uapi-prep-20121002' of 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

2f951a5db5 drm/nouveau/therm: add support for fan-control modes
For now, only 2 control modes are available:
- NONE: The fan is never touched (default)
- MANUAL: The fan is set to the user-defined fan speed (pwm1)

This patch introduces a distinction between ptherm internal fan management
and external fan management. The latter is bound to respect the fan mode
while the first can still select the speed it wants unless the NONE mode
is selected. This is important for automatic fan management.

bf6546b421 drm/nouveau/fan: rewrite the fan tachometer driver to get more precision, faster
The previous driver waited for 250ms to accumulate data. This version times a
complete fan rotation and extrapolates to RPM.

The fan rotational speed should now be read in less than 250ms (worst case)
and usually in less 50ms.

Further patches will fix the actual "driver" code and add new features.

v3: add a missing include

v4: Ben Skeggs <bskeggs@redhat.com>
- fixed set_defaults() to allow min_duty < 30 (thermal table will
  override this if it's actually necessary)
- fixed set_defaults() to not provide pwm_freq so nv4x (which only has

4c2d42225b drm/nouveau/core: have fifo store a unique context identifier at attach time
This value will match something that's easily available from the engine IRQ
handlers, and used to lookup the relevant context.

Since the changes in how this is done on each generation match when the
major PFIFO changes happened, fifo is responsible for calculating the
correct value to avoid duplicating the same code among many engine modules.

ebb945a94b drm/nouveau: port all engines to new engine module format
This is a HUGE commit, but it's not nearly as bad as it looks - any problems
can be isolated to a particular chipset and engine combination.  It was
simply too difficult to port each one at a time, the compat layers are
*already* ridiculous.

Most of the changes here are simply to the glue, the process for each of the
engine modules was to start with a standard skeleton and copy+paste the old
code into the appropriate places, fixing up variable names etc as needed.

9274f4a9ba drm/nouveau/core: pull in most of the new core infrastructure
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>

Remove redundant #inclusions of core DRM UAPI headers (drm.h, drm_mode.h and

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.

033d9959ed Merge branch 'for-3.7' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/wq
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.

833dd8224e drm/nvc0/fifo: ignore bits in PFIFO_INTR that aren't set in PFIFO_INTR_EN
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.

79eee7aa0d drm/nvc0/ltcg: mask off intr 0x10
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.

Merge tag 'v3.6-rc7' into drm-intel-next-queued

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 b98b601672
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 3cce574f01
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.

991083ba60 drm/nv50-/gpio: initialise to vbios defaults during init
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.

a348cd5fd8 drm/nvd0/disp: hopefully fix selection of 6/8bpc mode on DP outputs
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.

14f0458a41 drm/nvc0/copy: check PUNITS to determine which copy engines are disabled
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.

43829731dd workqueue: deprecate flush[_delayed]_work_sync()
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.
