Not used any more. And it is bad design to use a TTM flag
to do a check inside a driver.

Instead use a boolean field in the memory manager structure.

Also invert the meaning of the field since the use of a TT
structure is the special case here.

v2: cleanup zero init.

Subject: drm/ttm: remove the init_mem_type callback

It is a very strange concept to call a function which just
calls back the caller for the functions parameters.

Subject: drm/panel: remove return value of function drm_panel_add

The function "int drm_panel_add(struct drm_panel *panel)"
always returns 0, this return value is meaningless.
Also, there is no need to check return value which calls
"drm_panel_add and", error branch code will never run.

Drop the WARN_ON and consolidate the two paths into one.

Use the consolidate slowpath in the execbuf utils code.

Subject: drm/ttm: export memory type debug entrypoint.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

As suggested on review, just export the memory type debug for
drivers to use, while also making the debug callback optional
(don't need to test for system as it won't init it).

rename it to be more consistent with object name for now.
(we may rename all the objects later.)

This will allow the driver to control the ordering here better.

Eventually the old path will be removed.

rename new path to ttm_mem_type_manager_init/set_used(for now)

Subject: drm/ttm: make TTM responsible for cleaning system only.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Drivers should all be cleaning up their memory managers
themselves now, so let the core just clean the system one up.

Remove the legacy cleaning interface.

The driver now controls these, the core just controls the system
memory one.

v2: init sysman explicitly and assign it as a driver manager
to simplify the lookup sequence.

This converts vmwgfx over to using an interface to set the
in use and check the in use flag.

This name makes a lot more sense, since these are about managing
driver resources rather than just memory ranges.

From 2966141ad2dda23d1b37997de6a4389b7864c169 Mon Sep 17 00:00:00 2001

Subject: drm/ttm: rename ttm_mem_reg to ttm_resource.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This name better reflects what the object does. I didn't rename
all the pointers it seemed too messy.

Subject: drm: Remove unnecessary drm_panel_attach and drm_panel_detach

These functions are now empty and no longer
useful so remove the functions and their uses.

Subject: drm: report dp downstream port type as a subconnector property
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Currently, downstream port type is only reported in debugfs. This
information should be considered important since it reflects the actual
physical connector type. Some userspace (e.g. window compositors)
may want to show this info to a user.

The 'subconnector' property is already utilized for DVI-I and TV-out for
reporting connector subtype.

The initial motivation for this feature came from i2c test [1].
It is supposed to be skipped on VGA connectors, but it cannot
detect VGA over DP and fails instead.

v2:
 - Ville: utilized drm_dp_is_branch()
 - Ville: implement DP 1.0 downstream type info
 - Replaced create_dp_properties with add_dp_subconnector_property
 - Added dp_set_subconnector_property helper

v4:
 - Ville: add DP1.0 best assumption about subconnector
 - Ville: assume DVI is DVI-D
 - Ville: reuse Writeback enum value for Virtual subconnector
 - Renamed #defines: HDMI -> HDMIA, DP -> DisplayPort

v5: rebase

v6:
 - Jani Nikula: renamed a function name
 - Jani Nikula: addressed the issues with documentation

Subject: drm/modeset-lock: Take the modeset BKL for legacy drivers

This fell off in the conversion in

commit 9bcaa3fe58ab7559e71df798bcff6e0795158695
Author: Michal Orzel <michalorzel.eng@gmail.com>
Date:   Tue Apr 28 19:10:04 2020 +0200

    drm: Replace drm_modeset_lock/unlock_all with DRM_MODESET_LOCK_ALL_* helpers

but it's caught by the drm_warn_on_modeset_not_all_locked() that the
legacy modeset code uses. Since this is the bkl and it's unclear
what's all protected, play it safe and grab it again for legacy
drivers.

Unfortunately this means we need to sprinkle a few more #includes
around.

Also we need to add the drm_device as a parameter to the _END macro.

Finally remove the mute_lock() from setcrtc, since that's now done by
the macro.

Subject: drm/scheduler: Scheduler priority fixes (v2)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Remove DRM_SCHED_PRIORITY_LOW, as it was used
in only one place.

Rename and separate by a line
DRM_SCHED_PRIORITY_MAX to DRM_SCHED_PRIORITY_COUNT
as it represents a (total) count of said
priorities and it is used as such in loops
throughout the code. (0-based indexing is the
the count number.)

Remove redundant word HIGH in priority names,
and rename *KERNEL* to *HIGH*, as it really
means that, high.

v2: Add back KERNEL and remove SW and HW,
    in lieu of a single HIGH between NORMAL and KERNEL.

From 9af5e21dace795891544042abda877ada39abacc Mon Sep 17 00:00:00 2001
From: Luben Tuikov <luben.tuikov@amd.com>

Subject: drm/scheduler: Remove priority macro INVALID (v2)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Remove DRM_SCHED_PRIORITY_INVALID. We no longer
carry around an invalid priority and cut it off
at the source.

Backwards compatibility behaviour of AMDGPU CTX
IOCTL passing in garbage for context priority
from user space and then mapping that to
DRM_SCHED_PRIORITY_NORMAL is preserved.

v2: Revert "res"  --> "r" and
           "prio" --> "priority".

Subject: drm/i915/dp: Extract drm_dp_read_mst_cap()

Just a tiny drive-by cleanup, we can consolidate i915's code for
checking for MST support into a helper to be shared across drivers.

v5:
* Drop !!()
* Move drm_dp_has_mst() out of header
* Change name from drm_dp_has_mst() to drm_dp_read_mst_cap()

Subject: drm/i915/dp: Extract drm_dp_read_downstream_info()

We're going to be doing the same probing process in nouveau for
determining downstream DP port capabilities, so let's deduplicate the
work by moving i915's code for handling this into a shared helper:
drm_dp_read_downstream_info().

Note that when we do this, we also do make some functional changes while
we're at it:
* We always clear the downstream port info before trying to read it,
  just to make things easier for the caller
* We skip reading downstream port info if the DPCD indicates that we
  don't support downstream port info
* We only read as many bytes as needed for the reported number of
  downstream ports, no sense in reading the whole thing every time

v2:
* Fixup logic for calculating the downstream port length to account for
  the fact that downstream port caps can be either 1 byte or 4 bytes
  long. We can actually skip fixing the max_clock/max_bpc helpers here
  since they all check for DP_DETAILED_CAP_INFO_AVAILABLE anyway.
* Fix ret code check for drm_dp_dpcd_read
v5:
* Change name from drm_dp_downstream_read_info() to
  drm_dp_read_downstream_info()
* Also, add "See Also" sections for the various downstream info
  functions (drm_dp_read_downstream_info(), drm_dp_downstream_max_clock(),
  drm_dp_downstream_max_bpc())

Subject: drm/i915/dp: Extract drm_dp_read_sink_count_cap()

Since other drivers are also going to need to be aware of the sink count
in order to do proper dongle detection, we might as well steal i915's
DP_SINK_COUNT helpers and move them into DRM helpers so that other
dirvers can use them as well.

Note that this also starts using intel_dp_has_sink_count() in
intel_dp_detect_dpcd(), which is a functional change.

v5:
* Change name from drm_dp_has_sink_count() to
  drm_dp_read_sink_count_cap()

Subject: drm/i915/dp: Extract drm_dp_read_dpcd_caps()

Since DP 1.3, it's been possible for DP receivers to specify an
additional set of DPCD capabilities, which can take precedence over the
capabilities reported at DP_DPCD_REV.

Basically any device supporting DP is going to need to read these in an
identical manner, in particular nouveau, so let's go ahead and just move
this code out of i915 into a shared DRM DP helper that we can use in
other drivers.

v2:
* Remove redundant dpcd[DP_DPCD_REV] == 0 check
* Fix drm_dp_dpcd_read() ret checks

From 9ab57658a608f879469ffa22b723c4539c05a58f Mon Sep 17 00:00:00 2001
From: Sean Paul <seanpaul@chromium.org>
Date: Tue, 18 Aug 2020 11:38:49 -0400
Subject: drm/i915: Fix sha_text population code

This patch fixes a few bugs:

1- We weren't taking into account sha_leftovers when adding multiple
   ksvs to sha_text. As such, we were or'ing the end of ksv[j - 1] with
   the beginning of ksv[j]

2- In the sha_leftovers == 2 and sha_leftovers == 3 case, bstatus was
   being placed on the wrong half of sha_text, overlapping the leftover
   ksv value

3- In the sha_leftovers == 2 case, we need to manually terminate the
   byte stream with 0x80 since the hardware doesn't have enough room to
   add it after writing M0

The upside is that all of the HDCP supported HDMI repeaters I could
find on Amazon just strip HDCP anyways, so it turns out to be _really_
hard to hit any of these cases without an MST hub, which is not (yet)
supported. Oh, and the sha_leftovers == 1 case works perfectly!
