Huang Rui 7739b1e7e1 drm/amd/powerplay: add prefix for all powerplay pr_* prints
Powerplay will use them instead of raw printk, and we can dynamic
change the debug level with it.

The prefix is like below:

[  xxx.xxxxxx] amdgpu: [powerplay] ...

a new way to fetch out vbios/rom, until current vbios/rom is started with

Arindam Nath 44879b6261 drm/amd/amdgpu: get maximum and used UVD handles (v4)
Change History
--------------

v4: Changes suggested by Emil, Christian
- return -ENODATA for asics with unlimited sessions

v3: changes suggested by Christian
- Add a check for UVD IP block using AMDGPU_HW_IP_UVD
  query type.
- Add a check for asic_type to be less than
  CHIP_POLARIS10 since starting Polaris, we support
  unlimited UVD instances.
- Add kerneldoc style comment for
  amdgpu_uvd_used_handles().

v2: as suggested by Christian
- Add a new query AMDGPU_INFO_NUM_HANDLES
- Create a helper function to return the number
  of currently used UVD handles.
- Modify the logic to count the number of used
  UVD handles since handles can be freed in
  non-linear fashion.

v1:
- User might want to query the maximum number of UVD
  instances supported by firmware. In addition to that,
  if there are multiple applications using UVD handles
  at the same time, he might also want to query the
  currently used number of handles.

  For this we add two variables max_handles and
  used_handles inside drm_amdgpu_info_hw_ip. So now
  an application (or libdrm) can use AMDGPU_INFO IOCTL
  with AMDGPU_INFO_HW_IP_INFO query type to get these
  values.

Currently the pitch is passed in as depth.  This causes
drm_mode_legacy_fb_format() to return the wrong pixel format.

The wrong pixel format will be rejected by vmw_kms_new_framebuffer(),
thus leaving par->set_fb to NULL.

This eventually causes a crash in vmw_fb_setcolreg() when the code
tries to dereference par->set_fb.

Dave Airlie c4d79c2201 Reinstate "drm/probe-helpers: Drop locking from poll_enable""
This reverts commit 54a07c7bb0,
and reinstates the original.

[airlied: this might be a bad plan for git].

commit 3846fd9b86
Author: Daniel Vetter <daniel.vetter@ffwll.ch>
Date:   Wed Jan 11 10:01:17 2017 +0100

    drm/probe-helpers: Drop locking from poll_enable

    It was only needed to protect the connector_list walking, see

    commit 8c4ccc4ab6
    Author: Daniel Vetter <daniel.vetter@ffwll.ch>
    Date:   Thu Jul 9 23:44:26 2015 +0200

        drm/probe-helper: Grab mode_config.mutex in poll_init/enable

    Unfortunately the commit message of that patch fails to mention that
    the new locking check was for the connector_list.

    But that requirement disappeared in

    commit c36a3254f7
    Author: Daniel Vetter <daniel.vetter@ffwll.ch>
    Date:   Thu Dec 15 16:58:43 2016 +0100

        drm: Convert all helpers to drm_connector_list_iter

    and so we can drop this again.

    This fixes a locking inversion on nouveau, where the rpm code needs to
    re-enable. But in other places the rpm_get() calls are nested within
    the big modeset locks.

    While at it, also improve the kerneldoc for these two functions a
    notch.

    v2: Update the kerneldoc even more to explain that these functions
    can't be called concurrently, or bad things happen (Chris).

We perform the conversion between kernel jiffies and ms only when
exporting kernel value to user space.

We need to do the opposite operation when value is written by user.

Only matters when HZ != 1000

Pull drm revert from Dave Airlie:
 "Revert one patch missing some prereqs.

  One of the connector fixes was missing some prereqs, we have an
  alternate driver fix that should work that I'll send tomorrow.

  Today is a holiday here so quickly smashing this out"

Daniel Vetter explains:
 "I pushed a locking change to fix a nouveau rpm issue to -fixes that
  needed the connector_list rework. And that's only in -next, but I
  missed that. Dave has the revert in a pull, and he'll follow-up with
  the hack nouveau patch for 4.10, and then we'll reapply the proper fix
  again for -next and revert the hacks. A bit a mess, but should be
  sorted soon"

Ville Syrjälä fcc8a22cc9 drm/edid: Set YQ bits in the AVI infoframe according to CEA-861-F
CEA-861-F tells us:
"When transmitting any RGB colorimetry, the Source should set the
 YQ-field to match the RGB Quantization Range being transmitted
 (e.g., when Limited Range RGB, set YQ=0 or when Full Range RGB,
 set YQ=1) and the Sink shall ignore the YQ-field."

So let's go ahead and do that. Perhaps there are sinks that don't
ignore the YQ as they should for RGB?

I wasn't able to find similar text in CEA-861-E, so it would seem
to be a fairly "recent" addition.
