The DRM helper drm_fb_build_fourcc_list() creates a list of color
formats for primary planes of the generic drivers. Simplify the helper:
- It used to mix and filter native and emulated formats as provided
by the driver. Now the only emulated format is XRGB8888, which is
required as fallback by legacy software. Drop support for emulating
any other formats.
- Also convert alpha formats to their non-alpha counterparts. Generic
drivers don't support primary planes with alpha formats and some
DTs incorrectly advertise alpha channels for non-alpha hardware. So
only export non-alpha formats for primary planes.
With the simplified helper, scrap format lists of the affected generic
drivers. All they need is the firmware buffer's native format, from which
the helper creates the list of color formats.

Introduce the ability to track requests for the addition of DRM debugfs
files at any time and have them added all at once during
drm_dev_register().
Drivers can add DRM debugfs files to a device-managed list and, during
drm_dev_register(), all added files will be created at once.
Now, the drivers can use the functions drm_debugfs_add_file() and
drm_debugfs_add_files() to create DRM debugfs files instead of using the
drm_debugfs_create_files() function.

DSI sink devices typically want the DSI host powered up and configured
before they are powered up. pre_enable is the place this would normally
happen, but they are called in reverse order from panel/connector towards
the encoder, which is the "wrong" order.
Add a new flag pre_enable_prev_first that any bridge can set
to swap the order of pre_enable (and post_disable) for that and the
immediately previous bridge.
Should the immediately previous bridge also set the
pre_enable_prev_first flag, the previous bridge to that will be called
before either of those which requested pre_enable_prev_first.
eg:
- Panel
- Bridge 1
- Bridge 2 pre_enable_prev_first
- Bridge 3
- Bridge 4 pre_enable_prev_first
- Bridge 5 pre_enable_prev_first
- Bridge 6
- Encoder
Would result in pre_enable's being called as Panel, Bridge 1, Bridge 3,
Bridge 2, Bridge 6, Bridge 5, Bridge 4, Encoder.

perform a lookup of a TV mode name and return its value.

Multiple drivers (meson, vc4, sun4i) define analog TV 525-lines and
625-lines modes in their drivers.
Since those modes are fairly standard, and that we'll need to use them
in more places in the future, it makes sense to move their definition
into the core framework.
However, analog display usually have fairly loose timings requirements,
the only discrete parameters being the total number of lines and pixel
clock frequency. Thus, we created a function that will create a display
mode from the standard, the pixel frequency and the active area.

The TV mode property has been around for a while now to select and get the
current TV mode output on an analog TV connector.
Despite that property name being generic, its content isn't and has been
driver-specific which makes it hard to build any generic behaviour on top
of it, both in kernel and user-space.
Let's create a new enum tv norm property, that can contain any of the
analog TV standards currently supported by kernel drivers. Each driver can
then pass in a bitmask of the modes it supports, and the property
creation function will filter out the modes not supported.
We'll then be able to phase out the older tv mode property.

drm_mode_create_tv_properties(), among other things, will create the

However, that property is getting deprecated, so let's rename that

that function creating the property superseeding it in a later patch.

Since we're going to introduce a new, generic, property that fit the

The accelerator devices are exposed to user-space using a dedicated
major. In addition, they are represented in /dev with new, dedicated
device char names: /dev/accel/accel*. This is done to make sure any
user-space software that tries to open a graphic card won't open
the accelerator device by mistake.
The above implies that the minor numbering should be separated from
the rest of the DRM devices. However, to avoid code duplication, we
want the drm_minor structure to be able to represent the accelerator
device.
To achieve this, we add a new drm_minor* to drm_device that represents
the accelerator device. This pointer is initialized for drivers that
declare they handle compute accelerator, using a new driver feature
flag called DRIVER_COMPUTE_ACCEL. It is important to note that this
driver feature is mutually exclusive with DRIVER_RENDER. Devices that
want to expose both graphics and compute device char files should be
handled by two drivers that are connected using the auxiliary bus
framework.
In addition, we define a different IDR to handle the accelerators
minors. This is done to make the minor's index be identical to the
device index in /dev/. Any access to the IDR is done solely
by functions in accel_drv.c, as the IDR is define as static. The
DRM core functions call those functions in case they detect the minor's
type is DRM_MINOR_ACCEL.
We define a separate accel_open function (from drm_open) that the
accel drivers should set as their open callback function. Both these
functions eventually call the same drm_open_helper(), which had to be
changed to be non-static so it can be called from accel_drv.c.
accel_open() only partially duplicates drm_open as I removed some code
from it that handles legacy devices.
To help new drivers, I defined DEFINE_DRM_ACCEL_FOPS macro to easily
set the required function operations pointers structure.

Add a new Kconfig for the accel subsystem. The Kconfig currently
contains only the basic CONFIG_DRM_ACCEL option that will be used to
decide whether to compile the accel registration code. Therefore, the
kconfig option is defined as bool.
The accel code will be compiled as part of drm.ko and will be called
directly from the DRM core code. The reason we compile it as part of
drm.ko and not as a separate module is because of cyclic dependency
between drm.ko and the separate module (if it would have existed).
This is due to the fact that DRM core code calls accel functions and
vice-versa.
The accelerator devices will be exposed to the user space with a new,
dedicated major number - 261.
The accel init function registers the new major number as a char device
and create corresponding sysfs and debugfs root entries, similar to
what is done in DRM init function.
I added a new header called drm_accel.h to include/drm/, that will hold
the prototypes of the drm_accel.c functions. In case CONFIG_DRM_ACCEL
is set to 'N', that header will contain empty inline implementations of
those functions, to allow DRM core code to compile successfully
without dependency on CONFIG_DRM_ACCEL.
I Updated the MAINTAINERS file accordingly with the newly added folder
and I have taken the liberty to appropriate the dri-devel mailing list
and the dri-devel IRC channel for the accel subsystem.

Move the nomodeset kernel parameter to drivers/video to make it
available to non-DRM drivers. Adapt the interface, but keep the DRM
interface drm_firmware_drivers_only() to avoid churn within DRM. The
function should later be inlined into callers.
The parameter disables any DRM graphics driver that would replace a
driver for firmware-provided scanout buffers. It is an option to easily
fallback to basic graphics output if the hardware's native driver is
broken. Moving it to a more prominent location wil make it available
to fbdev as well.

This reverts commit e6c6338f39.
This feature basically re-submits one job after another to
figure out which one was the one causing a hang.
This is obviously incompatible with gang-submit which requires
that multiple jobs run at the same time. It's also absolutely
not helpful to crash the hardware multiple times if a clean
recovery is desired.
For testing and debugging environments we should rather disable
recovery alltogether to be able to inspect the state with a hw
debugger.
Additional to that the sw implementation is clearly buggy and causes

Move the vmap code for shadow-plane helpers from prepare_fb to
begin_fb_access helpers. Vunmap is now performed at the end of
the current pageflip, instead of the end of the following pageflip.
Reduces the duration of the mapping from while the framebuffer is
being displayed to just the atomic commit. This is safe as outside
of the pageflip, nothing should access the mapped buffer memory.
Unmapping the framebuffer BO memory early allows to reduce address-
space consumption and possibly allows for evicting the memory pages.
The change is effectively a rename of prepare_fb and cleanup_fb
implementations, plus updates to the shadow-plane init macro. As
there's no longer a prepare_fb helper for shadow planes, atomic
helpers will call drm_gem_plane_helper_prepare_fb() automatically.

For I/O memory, fb helpers now provide drm_fb_helper_cfb_read() and

The fbdev helpers implement a damage worker that forwards fbdev
updates to the DRM driver. The worker's update logic depends on
the generic fbdev emulation. Separate the two via function pointer.
The generic fbdev emulation sets struct drm_fb_helper_funcs.fb_dirty,
a new callback that hides the update logic from the damage worker.
It's not possible to use the generic logic with other fbdev emulation,
because it contains additional code for the shadow buffering that
the generic emulation employs.
DRM drivers with internal fbdev emulation can set fb_dirty to their
own implementation if they require damage handling; although no such
drivers currently exist.

There's a lot going on here, but the main thing is switching the
firmware EDID loader to use struct drm_edid. Unfortunately, it's
difficult to reasonably split to smaller pieces.
Convert the EDID loader to struct drm_edid. There's a functional change
in validation; it no longer tries to fix errors or filter invalid
blocks. It's stricter in this sense. Hopefully this will not be an
issue.
As a by-product, this change also allows HF-EEODB extended EDIDs to be
passed via override/firmware EDID.

Having the EDID override debugfs directly update the EDID property is
problematic. The update is partial only. The driver has no way of
knowing it's been updated. Mode list is not updated. It's an
inconsistent state.
Detach debugfs EDID override from the property update completely. Only
set and reset a separate override EDID copy from debugfs, and have it
take effect only at detect (via EDID read). The copy is at
connector->edid_override, protected by connector->edid_override_mutex.
This also brings override EDID closer to firmware EDID in behaviour.
Add validation of the override EDID which we completely lacked.
Note that IGT already forces a detect whenever tests update the override
EDID.

Follow the naming of both EDID override functions as well as
drm_edid_connector_update(). This also matches better what the function
does; a combination of EDID property update and add modes. Indeed it
should later be converted to call drm_edid_connector_update().

The fb_base in struct drm_mode_config has been unused for a long time.
Some drivers set it and some don't leading to a very confusing state
where the variable can't be relied upon, because there's no indication
as to which driver sets it and which doesn't.
The only usage of fb_base is internal to two drivers so instead of trying
to force it into all the drivers to get it into a coherent state
completely remove it.

The new common dma-buf locking convention will require buffer importers
to hold the reservation lock around mapping operations. Make DRM GEM core
to take the lock around the vmapping operations and update DRM drivers to
use the locked functions for the case where DRM core now holds the lock.
This patch prepares DRM core and drivers to the common dynamic dma-buf
locking convention.

There are some drivers that duplicate this logic in their helpers, such as

The subconnector property was created by drm_mode_create_tv_properties(),
but wasn't exposed to the userspace through the generic
atomic_get/set_property implementation, and wasn't stored in any generic
state structure.

There is two TV subconnector related properties registered by
drm_mode_create_tv_properties(): subconnector and select subconnector.
While the select subconnector property is stored in the kernel by the
drm_tv_connector_state structure, the subconnector property isn't stored
anywhere.
Worse, the select subconnector property is stored in a field called
subconnector, creating some ambiguity about which property content we're
accessing.
Let's rename that field to one called select_subconnector to make it move
obvious what it's about.

We currently have two sets of TV properties.
The first one is there to deal with analog TV properties, creating
properties such as the TV mode, subconnectors, saturation, hue and so on.
It's created by calling the drm_mode_create_tv_properties() function.
The second one is there to deal with properties that might be useful on a
TV, creating the overscan margins for example. It's created by calling the
drm_mode_create_tv_margin_properties().
However, we also have a drm_atomic_helper_connector_tv_reset() function
that will reset the TV margin properties to their default values, and thus
is supposed to be called for the latter set. This creates an ambiguity due
to the inconsistent naming.
We can thus rename the drm_atomic_helper_connector_tv_reset() function to
drm_atomic_helper_connector_tv_margins_reset() to remove that ambiguity
and hopefully make it more obvious.

Rename the atomic helper function drm_atomic_helper_check_crtc_state()
to drm_atomic_helper_check_crtc_primary_plane() and only check for an
attached primary plane. Adapt callers.
Instead of having one big function to check for various CRTC state
conditions, we rather want smaller functions that drivers can pick
individually.

When many entities are competing for the same run queue
on the same scheduler, we observe an unusually long wait
times and some jobs get starved. This has been observed on GPUVis.
The issue is due to the Round Robin policy used by schedulers
to pick up the next entity's job queue for execution. Under stress
of many entities and long job queues within entity some
jobs could be stuck for very long time in it's entity's
queue before being popped from the queue and executed
while for other entities with smaller job queues a job
might execute earlier even though that job arrived later
then the job in the long queue.
Fix:
Add FIFO selection policy to entities in run queue, chose next entity
on run queue in such order that if job on one entity arrived
earlier then job on another entity the first job will start
executing earlier regardless of the length of the entity's job
queue.
v2:
Switch to rb tree structure for entities based on TS of
oldest job waiting in the job queue of an entity. Improves next
entity extraction to O(1). Entity TS update
O(log N) where N is the number of entities in the run-queue
Drop default option in module control parameter.

upgrade the callchain to drm_dbg() and drm_dev_dbg(); add a struct
_ddebug ptr parameter to them, and supply that additional param by
replacing the '_no_desc' flavor of dyndbg Factory macro currently used
with the flavor that supplies the descriptor.
NOTES:
The descriptor gives these fns access to the decorator flags, but they
do none of the dynamic-prefixing done by dynamic_emit_prefix(), which
is currently static.
DRM already has conventions for logging/messaging; just tossing
optional decorations on top probably wouldn't help. Instead, existing
flags (or new ones, perhaps 'sd' ala lspci) can be used to make
current message conventions optional. This suggests a new
drmdbg_prefix_emit() to handle prefixing locally.
For CONFIG_DRM_USE_DYNAMIC_DEBUG=N, just pass null descriptor.
desc->class_id is redundant with category parameter, but its
availability is dependent on desc.

When CONFIG_DRM_USE_DYNAMIC_DEBUG=y, the drm.debug API (a macro stack,
calling _+drm_*dbg() eventually) invokes a dyndbg Factory macro to
create a descriptor for each callsite, thus making them individually
>control-able.
In this case, the calls to _drm_*dbg are unreachable unless the
callsite is enabled. So those calls can short-circuit their early
do-nothing returns. Provide and use __drm_debug_enabled(), to do this
when config'd, or the _raw flags-check otherwize.
And since dyndbg is in use, lets also instrument the remaining users
of drm_debug_enabled, by wrapping the _raw in a macro with a:
pr_debug("todo: is this frequent enough to optimize ?\n");
For CONFIG_DRM_USE_DYNAMIC_DEBUG=n, do no site instrumenting at all,
since JUMP_LABEL might be off, and we don't want to make work.
With drm, amdgpu, i915, nouveau loaded, heres remaining uses of
drm_debug_enabled(), which costs ~1.5kb data to control the
pr_debug("todo:..")s.
Some of those uses might be ok to use __drm_debug_enabled() by
inspection, others might warrant conversion to use dyndbg Factory
macros, and that would want callrate data to estimate the savings
possible. TBH, any remaining savings are probably small; drm.debug
covers the vast bulk of the uses. Maybe "vblank" is the exception.

drm_print defines all of these:

but not drm_dbg_driver itself, since it was the original drm_dbg.
To improve namespace symmetry, change the drm_dbg defn to
drm_dbg_driver, and redef grandfathered name to symmetric one.
This will help with nouveau, which uses its own stack of macros to
construct calls to dev_info, dev_dbg, etc, for which adaptation means
drm_dbg_##driver constructs.

For CONFIG_DRM_USE_DYNAMIC_DEBUG=y, wrap __drm_dbg() & __drm_dev_dbg()
in one of dyndbg's Factory macros: _dynamic_func_call_no_desc().
This adds the callsite descriptor into the code, and an entry for each
into /proc/dynamic_debug/control.
#> echo class DRM_UT_ATOMIC +p > /proc/dynamic_debug/control
CONFIG_DRM_USE_DYNAMIC_DEBUG=y/n is configurable because of the .data
footprint cost of per-callsite control; 56 bytes/site * ~2k for i915,
~4k callsites for amdgpu. This is large enough that a kernel builder
might not want it.

change drm_dev_dbg & drm_dbg to macros, which forward to the renamed
functions (with __ prefix added).
Those functions sit below the categorized layer of macros implementing
the DRM debug.category API, and implement most of it. These are good
places to insert dynamic-debug jump-label mechanics, which will allow
DRM to avoid the runtime cost of drm_debug_enabled().
no functional changes.

Use DECLARE_DYNDBG_CLASSMAP across DRM:
- in .c files, since macro defines/initializes a record
- in drivers, $mod_{drv,drm,param}.c
ie where param setup is done, since a classmap is param related
- in drm/drm_print.c
since existing __drm_debug param is defined there,
and we ifdef it, and provide an elaborated alternative.
- in drm_*_helper modules:
dp/drm_dp - 1st item in makefile target
drivers/gpu/drm/drm_crtc_helper.c - random pick iirc.
Since these modules all use identical CLASSMAP declarations (ie: names
and .class_id's) they will all respond together to "class DRM_UT_*"
query-commands:
:#> echo class DRM_UT_KMS +p > /proc/dynamic_debug/control
NOTES:
This changes __drm_debug from int to ulong, so BIT() is usable on it.
DRM's enum drm_debug_category values need to sync with the index of
their respective class-names here. Then .class_id == category, and
dyndbg's class FOO mechanisms will enable drm_dbg(DRM_UT_KMS, ...).
Though DRM needs consistent categories across all modules, thats not
generally needed; modules X and Y could define FOO differently (ie a
different NAME => class_id mapping), changes are made according to
each module's private class-map.
No callsites are actually selected by this patch, since none are
class'd yet.

enum drm_debug_category has 10 categories, but is initialized with
bitmasks which require 10 bits of underlying storage. By using
natural enumeration, and moving the BIT(cat) into drm_debug_enabled(),
the enum fits in 4 bits, allowing the category to be represented
directly in pr_debug callsites, via the ddebug.class_id field.
While this slightly pessimizes the bit-test in drm_debug_enabled(),
using dyndbg with JUMP_LABEL will avoid the function entirely.
NOTE: this change forecloses the possibility of doing:
drm_dbg(DRM_UT_CORE|DRM_UT_KMS, "weird 2-cat experiment")
but thats already strongly implied by the use of the enum itself; its
not a normal enum if it can be 2 values simultaneously.

Similar to HDMI, DP uses audio infoframes as well which are structured
very similar to the HDMI ones.
This patch adds a helper function to pack the HDMI audio infoframe for
DP, called hdmi_audio_infoframe_pack_for_dp().
hdmi_audio_infoframe_pack_only() is split into two parts. One of them
packs the payload only and can be used for HDMI and DP.
Also constify the frame parameter in hdmi_audio_infoframe_check() as
it is passed to hdmi_audio_infoframe_check_only() which expects a const.

Now that we've finally gotten rid of the non-atomic MST users leftover in
the kernel, we can finally get rid of all of the legacy payload code we
have and move as much as possible into the MST atomic state structs. The
main purpose of this is to make the MST code a lot less confusing to work
on, as there's a lot of duplicated logic that doesn't really need to be
here. As well, this should make introducing features like fallback link
retraining and DSC support far easier.
Since the old payload code was pretty gnarly and there's a Lot of changes
here, I expect this might be a bit difficult to review. So to make things
as easy as possible for reviewers, I'll sum up how both the old and new
code worked here (it took me a while to figure this out too!).
The old MST code basically worked by maintaining two different payload
tables - proposed_vcpis, and payloads. proposed_vcpis would hold the
modified payload we wanted to push to the topology, while payloads held the
payload table that was currently programmed in hardware. Modifications to
proposed_vcpis would be handled through drm_dp_allocate_vcpi(),
drm_dp_mst_deallocate_vcpi(), and drm_dp_mst_reset_vcpi_slots(). Then, they
would be pushed via drm_dp_mst_update_payload_step1() and
drm_dp_mst_update_payload_step2().
Furthermore, it's important to note how adding and removing VC payloads
actually worked with drm_dp_mst_update_payload_step1(). When a VC payload
is removed from the VC table, all VC payloads which come after the removed
VC payload's slots must have their time slots shifted towards the start of
the table. The old code handles this by looping through the entire payload
table and recomputing the start slot for every payload in the topology from
scratch. While very much overkill, this ends up doing the right thing
because we always order the VCPIs for payloads from first to last starting
timeslot.
It's important to also note that drm_dp_mst_update_payload_step2() isn't
actually limited to updating a single payload - the driver can use it to
queue up multiple payload changes so that as many of them can be sent as
possible before waiting for the ACT. This is -technically- not against
spec, but as Wayne Lin has pointed out it's not consistently implemented
correctly in hubs - so it might as well be.
drm_dp_mst_update_payload_step2() is pretty self explanatory and basically
the same between the old and new code, save for the fact we don't have a
second step for deleting payloads anymore -and thus rename it to
drm_dp_mst_add_payload_step2().
The new payload code stores all of the current payload info within the MST
atomic state and computes as much of the state as possible ahead of time.
This has the one exception of the starting timeslots for payloads, which
can't be determined at atomic check time since the starting time slots will
vary depending on what order CRTCs are enabled in the atomic state - which
varies from driver to driver. These are still stored in the atomic MST
state, but are only copied from the old MST state during atomic commit
time. Likewise, this is when new start slots are determined.
Adding/removing payloads now works much more closely to how things are
described in the spec. When we delete a payload, we loop through the
current list of payloads and update the start slots for any payloads whose
time slots came after the payload we just deleted. Determining the starting
time slots for new payloads being added is done by simply keeping track of
where the end of the VC table is in
drm_dp_mst_topology_mgr->next_start_slot. Additionally, it's worth noting
that we no longer have a single update_payload() function. Instead, we now
have drm_dp_mst_add_payload_step1|2() and drm_dp_mst_remove_payload(). As
such, it's now left it up to the driver to figure out when to add or remove
payloads. The driver already knows when it's disabling/enabling CRTCs, so
it also already knows when payloads should be added or removed.
Changes since v1:
* Refactor around all of the completely dead code changes that are
happening in amdgpu for some reason when they really shouldn't even be
there in the first place… :\
* Remove mention of sending one ACT per series of payload updates. As Wayne
Lin pointed out, there are apparently hubs on the market that don't work
correctly with this scheme and require a separate ACT per payload update.
* Fix accidental drop of mst_mgr.lock - Wayne Lin
* Remove mentions of allowing multiple ACT updates per payload change,
mention that this is a result of vendors not consistently supporting this
part of the spec and requiring a unique ACT for each payload change.
* Get rid of reference to drm_dp_mst_port in DC - turns out I just got
myself confused by DC and we don't actually need this.
Changes since v2:
* Get rid of fix for not sending payload deallocations if ddps=0 and just

Currently, we set drm_dp_atomic_payload->time_slots to 0 in order to
indicate that we're about to delete a payload in the current atomic state.
Since we're going to be dropping all of the legacy code for handling the
payload table however, we need to be able to ensure that we still keep
track of the current time slot allocations for each payload so we can reuse
this info when asking the root MST hub to delete payloads. We'll also be
using it to recalculate the start slots of each VC.
So, let's keep track of the intent of a payload in drm_dp_atomic_payload by
adding ->delete, which we set whenever we're planning on deleting a payload
during the current atomic commit.

There's another kind of situation where we could potentially race with
nonblocking modesets and MST, especially if we were to only use the locking
provided by atomic modesetting:
* Display 1 begins as enabled on DP-1 in SST mode
* Display 1 switches to MST mode, exposes one sink in MST mode
* Userspace does non-blocking modeset to disable the SST display
* Userspace does non-blocking modeset to enable the MST display with a
different CRTC, but the SST display hasn't been fully taken down yet
* Execution order between the last two commits isn't guaranteed since they
share no drm resources
We can fix this however, by ensuring that we always pull in the atomic
topology state whenever a connector capable of driving an MST display
performs its atomic check - and then tracking CRTC commits happening on the
SST connector in the MST topology state. So, let's add some simple helpers
for doing that and hook them up in various drivers.

As Daniel Vetter pointed out, if we only use the atomic modesetting locks
with MST it's technically possible for a driver with non-blocking modesets
to race when it comes to MST displays - as we make the mistake of not doing
our own CRTC commit tracking in the topology_state object.
This could potentially cause problems if something like this happens:
* User starts non-blocking commit to disable CRTC-1 on MST topology 1
* User starts non-blocking commit to enable CRTC-2 on MST topology 1
There's no guarantee here that the commit for disabling CRTC-2 will only
occur after CRTC-1 has finished, since neither commit shares a CRTC - only
the private modesetting object for MST. Keep in mind this likely isn't a
problem for blocking modesets, only non-blocking.
So, begin fixing this by keeping track of which CRTCs on a topology have
changed by keeping track of which CRTCs we release or allocate timeslots
on. As well, add some helpers for:
* Setting up the drm_crtc_commit structs in the ->commit_setup hook
* Waiting for any CRTC dependencies from the previous topology state
v2:
* Use drm_dp_mst_atomic_setup_commit() directly - Jani

VCPI is only sort of the correct term here, originally the majority of this
code simply referred to timeslots vaguely as "slots" - and since I started
working on it and adding atomic functionality, the name "VCPI slots" has
been used to represent time slots.
Now that we actually have consistent access to the DisplayPort spec thanks
to VESA, I now know this isn't actually the proper term - as the
specification refers to these as time slots.
Since we're trying to make this code as easy to figure out as possible,
let's take this opportunity to correct this nomenclature and call them by
their proper name - timeslots. Likewise, we rename various functions
appropriately, along with replacing references in the kernel documentation
and various debugging messages.
It's important to note that this patch series leaves the legacy MST code
untouched for the most part, which is fine since we'll be removing it soon
anyhow. There should be no functional changes in this series.

In retrospect, the name I chose for this originally is confusing, as
there's a lot more info in here then just the VCPI. This really should be
called a payload. Let's make it more obvious that this is meant to be
related to the atomic state and is about payloads by renaming it to
drm_dp_mst_atomic_payload. Also, rename various variables throughout the
code that use atomic payloads.
