Daniel Vetter 6e9f798d91 drm: Split connection_mutex out of mode_config.mutex (v3)
After the split-out of crtc locks from the big mode_config.mutex
there's still two major areas it protects:
- Various connector probe states, like connector->status, EDID
  properties, probed mode lists and similar information.
- The links from connector->encoder and encoder->crtc and other
  modeset-relevant connector state (e.g. properties which control the
  panel fitter).

The later is used by modeset operations. But they don't really care
about the former since it's allowed to e.g. enable a disconnected VGA
output or with a mode not in the probed list.

Thus far this hasn't been a problem, but for the atomic modeset
conversion Rob Clark needs to convert all modeset relevant locks into
w/w locks. This is required because the order of acquisition is
determined by how userspace supplies the atomic modeset data. This has
run into troubles in the detect path since the i915 load detect code
needs _both_ protections offered by the mode_config.mutex: It updates
probe state and it needs to change the modeset configuration to enable
the temporary load detect pipe.

The big deal here is that for the probe/detect users of this lock a
plain mutex fits best, but for atomic modesets we really want a w/w
mutex. To fix this lets split out a new connection_mutex lock for the
modeset relevant parts.

For simplicity I've decided to only add one additional lock for all
connector/encoder links and modeset configuration states. We have
piles of different modeset objects in addition to those (like bridges
or panels), so adding per-object locks would be much more effort.

Also, we're guaranteed (at least for now) to do a full modeset if we
need to acquire this lock. Which means that fine-grained locking is
fairly irrelevant compared to the amount of time the full modeset will
take.

I've done a full audit, and there's just a few things that justify
special focus:
- Locking in drm_sysfs.c is almost completely absent. We should
  sprinkle mode_config.connection_mutex over this file a bit, but
  since it already lacks mode_config.mutex this patch wont make the
  situation any worse. This is material for a follow-up patch.

- omap has a omap_framebuffer_flush function which walks the
  connector->encoder->crtc links and is called from many contexts.
  Some look like they don't acquire mode_config.mutex, so this is
  already racy. Again fixing this is material for a separate patch.

- The radeon hot_plug function to retrain DP links looks at
  connector->dpms. Currently this happens without any locking, so is
  already racy. I think radeon_hotplug_work_func should gain
  mutex_lock/unlock calls for the mode_config.connection_mutex.

- Same applies to i915's intel_dp_hot_plug. But again, this is already
  racy.

- i915 load_detect code needs to acquire this lock. Which means the
  w/w dance due to Rob's work will be nicely contained to _just_ this
  function.

I've added fixme comments everywhere where it looks suspicious but in
the sysfs code. After a quick irc discussion with Dave Airlie it
sounds like the lack of locking in there is due to sysfs cleanup fun
at module unload.

v1: original (only compile tested)

v2: missing mutex_init(), etc (from Rob Clark)

v3: i915 needs more care in the conversion:
- Protect the edp pp logic with the connection_mutex.
- Use connection_mutex in the backlight code due to
  get_pipe_from_connector.
- Use drm_modeset_lock_all in suspend/resume paths.
- Update lock checks in the overlay code.

Rob Clark 5ea22f24d7 drm: add extended property types
If we continue to use bitmask for type, we will quickly run out of room

continues to function as before, but reserve a chunk of the remaining
space for an integer type-id.  Wrap this all up in some type-check
helpers to keep the backwards-compat uglyness contained.

David Mansfield 52571ad5f4 drm/qxl: use surface_id 0 for primary surface on all monitors
spice-server and downstream code expect that the primary surface
will always have surface_id = 0, while in reality, once allocated, the
surface_id in qxl.ko is NEVER 0.  In a dual head environment, all
monitors render portions of the primary surface.

However, when the monitor config events are generated and sent,
the primary surface is only mapped to the correct identifier
(i.e. 0) for the primary head (where crtc index is 0).

The fix is to look at the "primary" flag in the bo and always
use id 0, irrespective of which head is being configured.

[airlied: qxl hw really needs to be fixed to scanout surfaces]

Mario Kleiner 89b92339c1 drm/radeon: Limit hdmi deep color bit depth to 12 bpc.
DCE-4/5/6 can't support more than 12 bpc deep color over hdmi,
so clamp to 12 bpc when a hdmi deep color capable display is
connected. This even makes sense on DCE-8+, which could do up
to 16 bpc, as driving with more than 12 bpc would only waste
video bandwidth as long as we don't support framebuffers with
more than 12 bpc depth.

On pre-DCE4 we clamp hdmi bit depth to 8 bpc, as those asics
don't support hdmi deep color.

Rafał Miłecki 8e4d9f8180 drm/radeon/hdmi: DCE2: simplify audio workaround
Thanks to advanced RE of fglrx we finally know what exactly needs to be
handled of AFMT change.

This has been tested for possible regressions on:
1) DCE2 HD2400 (RV610)
2) DCE3 HD3470 (RV620)

Rafał Miłecki 68706337da drm/radeon/hdmi: DCE2: update setmode
Recent RE efforts revealed ops performed by fglrx during HDMI setup.
This mostly adds masks to r/w ops plus few single missing bits.

This has been tested for possible regressions on:
1) DCE2 HD2400 (RV610)
2) DCE3 HD3470 (RV620)

Rafał Miłecki 2e93cac90c drm/radeon/hdmi: DCE3: clean ACR control
What initially seemed to be a typo in fglrx (using register 0x740c
instead of 0x74dc) appeared to be a correct behavior. DCE3 has ACR and
CRC registers swapped which explains why we needed
WREG32(HDMI0_AUDIO_CRC_CONTROL + offset, 0x1000);

This has been tested for possible regressions on DCE3 HD3470 (RV620).

Rafał Miłecki 8f33a156c2 drm/radeon/hdmi: use separated file for DCE 3.1/3.2 code
DCE 3.1 and 3.2 should be programmed in a different way than DCE 2 and
DCE 3. The order of setting registers and sets of registers are
different.
It's still unsure how we will handle DCE 3.1 vs. DCE 3.2, since they
have few differences as well.
For now separate DCE 2 and DCE 3 path, so we can work on it without a
risk of breaking DCE 3.1+.

This has been tested for possible regressions on DCE32 HD4550 (RV710).

Christian König ec3dbbcbd7 drm/radeon: add large PTE support for NI, SI and CIK v5
This patch implements support for VRAM page table entry compression.
PTE construction is enhanced to identify physically contiguous page
ranges and mark them in the PTE fragment field. L1/L2 TLB support is
enabled for 64KB (SI/CIK) and 256KB (NI) PTE fragments, significantly
improving TLB utilization for VRAM allocations.

Linear store bandwidth is improved from 60GB/s to 125GB/s on Pitcairn.
Unigine Heaven 3.0 sees an average improvement from 24.7 to 27.7 FPS
on default settings at 1920x1200 resolution with vsync disabled.

See main comment in radeon_vm.c for a technical description.

v2 (chk): rebased and simplified.
v3 (chk): add missing hw setup
v4 (chk): rebased on current drm-fixes-3.15
v5 (chk): fix comments and commit text
