Marek Olšák 67e8e3f970 drm/radeon: track memory statistics about VRAM and GTT usage and buffer moves v2
The statistics are:
- VRAM usage in bytes
- GTT usage in bytes
- number of bytes moved by TTM

The last one is actually a counter, so you need to sample it before and after
command submission and take the difference.

This is useful for finding performance bottlenecks. Userspace queries are
also added.

v2: use atomic64_t

Dave Airlie f5395ba35f Merge branch 'drm-vbl-timestamp' of git://gitorious.org/vsyrjala/linux into drm-next
Here's the vblank timestamp pull request you wanted.

I addressed the few bugs that Mario pointed out and added
the r-bs.

As it has been a while since I made the changes, I gave it a
quick spin on a few different i915 machines. Fortunately
everything still seems to be fine.

* 'drm-vbl-timestamp' of git://gitorious.org/vsyrjala/linux:
  drm/i915: Add a kludge for DSL incrementing too late and ISR not working
  drm/radeon: Move the early vblank IRQ fixup to radeon_get_crtc_scanoutpos()
  drm: Pass 'flags' from the caller to .get_scanout_position()
  drm: Fix vblank timestamping constants for interlaced modes
  drm/i915: Fix scanoutpos calculations for interlaced modes
  drm: Change {pixel,line,frame}dur_ns from s64 to int
  drm: Use crtc_clock in drm_calc_timestamping_constants()
  drm/radeon: Populate crtc_clock in radeon_atom_get_tv_timings()
  drm: Simplify the math in drm_calc_timestamping_constants()
  drm: Improve drm_calc_timestamping_constants() documentation
  drm/i915: Call drm_calc_timestamping_constants() earlier
  drm/i915: Kill hwmode save/restore
  drm: Pass the display mode to drm_calc_vbltimestamp_from_scanoutpos()
  drm: Pass the display mode to drm_calc_timestamping_constants()

you want me to frob it for you a bit.

Tom Stellard e5b9e7503e drm/radeon/si: Add support for CP DMA to CS checker for compute v2
Also add a new RADEON_INFO query to check that CP DMA packets are
supported on the compute ring.

CP DMA has been supported since the 3.8 kernel, but due to an oversight
we forgot to teach the CS checker that the CP DMA packet was legal for
the compute ring on Southern Islands GPUs.

This patch fixes a bug where the radeon driver will incorrectly reject a legal
CP DMA packet from user space.  I would like to have the patch
backported to stable so that we don't have to require Mesa users to use a
bleeding edge kernel in order to take advantage of this feature which
is already present in the stable kernels (3.8 and newer).

v2:
  - Don't bump kms version, so this patch can be backported to stable
    kernels.

Linus Torvalds 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.

David Howells 4126d5d61f UAPI: (Scripted) Remove redundant DRM UAPI header #inclusions from drivers/gpu/.
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.

Christian Koenig fb98257a9d drm/radeon: apply Murphy's law to the kms irq code v3
1. It is really dangerous to have more than one
   spinlock protecting the same information.

2. radeon_irq_set sometimes wasn't called with lock
   protection, so it can happen that more than one
   CPU would tamper with the irq regs at the same
   time.

3. The pm.gui_idle variable was assuming that the 3D
   engine wasn't becoming idle between testing the
   register and setting the variable. So just remove
   it and test the register directly.

v2: Also handle the hpd irq code the same way.
v3: Rename hpd parameter for clarification.
