57738ae40f drm/amd/display: do not dereference on NULL
WARN_ON() will not kill the process so the second WARN_ON()
will try to dereference NULL pointer.

71b970c868 drm/dp_mst: Use kHz as link rate units when settig source max link caps at init
[why]
Link rate in kHz is what is eventually required to calculate the link
bandwidth, which makes kHz a more generic unit. This should also make
forward-compatibility with new DP standards easier.

[how]
- Replace 'link rate DPCD code' with 'link rate in kHz' when used with
drm_dp_mst_topology_mgr_init()
- Add/remove related DPCD code conversion from/to kHz where applicable

580204038f drm/amd/display: Enable support for 16 bpc fixed-point framebuffers.
This is intended to enable direct high-precision scanout and pageflip
of Vulkan swapchain images in format VK_FORMAT_R16G16B16A16_UNORM.

Expose DRM_FORMAT_XRGB16161616, DRM_FORMAT_ARGB16161616,
DRM_FORMAT_XBGR16161616 and DRM_FORMAT_ABGR16161616 as 16 bpc
unsigned normalized formats. These allow to take full advantage
of the maximum precision of the display hardware, ie. currently
up to 12 bpc.

Searching through old AMD M56, M76 and RV630 hw programming docs
suggests that these 16 bpc formats are supported by all DCE and
DCN display engines, so we can expose the formats unconditionally.

Successfully tested on AMD Polaris11 DCE-11.2 an RavenRidge DCN-1.0
with a HDR-10 monitor over 10 bpc DP output with spatial dithering
enabled by the driver. Picture looks good, and my photometer
measurement procedure confirms an effective 12 bpc color
reproduction.

92e2b820dd drm/amd/display: Make assert in DCE's program_bit_depth_reduction more lenient.
This is needed to avoid warnings with linebuffer depth 36 bpp.
Testing on a Polaris11, DCE-11.2 on a 10 bit HDR-10 monitor
showed no obvious problems, and this 12 bpc limit is consistent
with what other function in the DCE bit depth reduction path use.

a316db7209 drm/amd/display: Increase linebuffer pixel depth to 36bpp.
Testing with the photometer shows that at least Raven Ridge DCN-1.0
does not achieve more than 10 bpc effective output precision with a
16 bpc unorm surface of type SURFACE_PIXEL_FORMAT_GRPH_ABGR16161616,
unless linebuffer depth is increased from LB_PIXEL_DEPTH_30BPP to
LB_PIXEL_DEPTH_36BPP. Otherwise precision gets truncated somewhere
to 10 bpc effective depth.

Strangely this increase was not needed on Polaris11 DCE-11.2 during
testing to get 12 bpc effective precision. It also is not needed for
fp16 framebuffers.

Tested on DCN-1.0 and DCE-11.2.

050cd3d616 drm/amd/display: Add support for SURFACE_PIXEL_FORMAT_GRPH_ABGR16161616.
Add the necessary format definition, bandwidth and pixel size mappings,
prescaler setup, and pixelformat selection, following the logic
already present for SURFACE_PIXEL_FORMAT_GRPH_ARGB16161616.

The new SURFACE_PIXEL_FORMAT_GRPH_ABGR16161616 is implemented as the
old SURFACE_PIXEL_FORMAT_GRPH_ARGB16161616 format, but with swapped
red <-> green color channel, by use of the hardware xbar.

Please note that on the DCN 1/2/3 display engines, the pixelformat
in hubp and dpp setup for the old SURFACE_PIXEL_FORMAT_GRPH_ARGB16161616
and the new SURFACE_PIXEL_FORMAT_GRPH_ABGR16161616 was changed from
format id 22 to id 26. See amd/include/navi10_enum.h for the meaning
of the id's.

For format 22, the display engine read the framebuffer in 16 bpc format,
but truncated to the 12 bpc actually supported by later pipeline stages.
However, the engine took the 12 LSB of each color component for
truncation, which is incompatible with rendering at least under Vulkan,
where content is 16 bit wide, and a 12 MSB alignment would be appropriate,
if any. Format 20 for ARGB16161616_12MSB does work, but even better, we
can choose format 26 for ARGB16161616_UNORM, keeping all 16 bits around
until later stages of the display pipeline.

This allows to directly consume what the rendering hw produces under
Vulkan for swapchain format VK_FORMAT_R16G16B16A16_UNORM, as tested
with a patched version of the current AMD open-source amdvlk driver
which maps swapchain format VK_FORMAT_R16G16B16A16_UNORM onto
DRM_FORMAT_XBGR16161616.

The old id 22 would cause colorful pixeltrash to be displayed instead.

Tested under DCN-1.0 and DCE-11.2.

They are global ACPI methods, so maybe the structures
global in the driver. This simplified a number of things
in the handling of these methods.

v2: reset the handle if verify interface fails (Lijo)
v3: fix compilation when ACPI is not defined.

e8ce3d474f drm/amd/display: Fix overlay validation by considering cursors
A few weeks ago, we saw a two cursor issue in a ChromeOS system. We
fixed it in the commit:

 drm/amd/display: Fix two cursor duplication when using overlay
 (read the commit message for more details)

After this change, we noticed that some IGT subtests related to
kms_plane and kms_plane_scaling started to fail. After investigating
this issue, we noticed that all subtests that fail have a primary plane
covering the overlay plane, which is currently rejected by amdgpu dm.
Fail those IGT tests highlight that our verification was too broad and
compromises the overlay usage in our drive. This patch fixes this issue
by ensuring that we only reject commits where the primary plane is not
fully covered by the overlay when the cursor hardware is enabled. With
this fix, all IGT tests start to pass again, which means our overlay
support works as expected.

b0781603af drm/amd/display: Fix GPU scaling regression by FS video support
[Why]
FS video support regressed GPU scaling and the scaled buffer ends up
stuck in the top left of the screen at native size - full, aspect,
center scaling modes do not function.

This is because decide_crtc_timing_for_drm_display_mode() does not
get called when scaling is enabled.

[How]
Split recalculate timing and scaling into two different flags.

We don't want to call drm_mode_set_crtcinfo() for scaling, but we
do want to call it for FS video.

Optimize and move preferred_refresh calculation next to
decide_crtc_timing_for_drm_display_mode() like it used to be since
that's not used for FS video.

We don't need to copy over the VIC or polarity in the case of FS video
modes because those don't change.

d2aa135683 drm/amd/display: take dc_lock in short pulse handler only
[Why]
Conditions that end up modifying the global dc state must be locked.
However, during mst allocate payload sequence, lock is already taken.
With StarTech 1.2 DP hub, we get an HPD RX interrupt for a reason other
than to indicate down reply availability right after sending payload
allocation. The handler again takes dc lock before calling the
dc's HPD RX handler. Due to this contention, the DRM thread which waits
for MST down reply never gets a chance to finish its waiting
successfully and ends up timing out. Once the lock is released, the hpd
rx handler fires and goes ahead to read from the MST HUB, but now its
too late and the HUB doesnt lightup all displays since DRM lacks error
handling when payload allocation fails.

[How]
Take lock only if there is a change in link status or if automated test
pattern bit is set. The latter fixes the null pointer dereference when
running certain DP Link Layer Compliance test.

3ca402375a drm/amd/display: Refactor and add visual confirm for HW Flip Queue
[Why]
Visual confirm will indicate if driver is programming
the surface address.
Refactor is required because much of the visual confirm
logic is buried deep in the mpcc files.
In addition, visual confirm is not updated during fast updates.

[How]
In order to have visual confirm for driver flips, visual confirm
needs to be updated on every frame, including fast updates.
Add a new hw sequencer interface update_visual_confirm_color,
and a new mpc function pointer set_bg_color.

60d177fdf8 drm/amd/display: Use the correct max downscaling value for DCN3.x family
[why]
As per spec, DCN3.x can do 6:1 downscaling and DCN2.x can do 4:1. The
max downscaling limit value for DCN2.x is 250, which means it's
calculated as 1000 / 4 = 250. For DCN3.x this then gives 1000 / 6 = 167.

[how]
Set maximum downscaling limit to 167 for DCN3.x

3bb68cec4d drm/amd/display: Add Overflow check to skip MALL
[Why]
In some small modes (<200pixels) the stutter period is really big and will cause
overflow. In these cases we shouldnt try to enable MALL as it will exceeds range
of hysteresis timer (this can be seen in some IGT tests where the
plane size is small)

[How]
Compare the stutter_period with the frame time and if we will overflow
there is no point in trying to enable MALL (and see the ASSERT) so we
early exist in this case

132c894e93 drm/amd/display: treat memory as a single-channel for asymmetric memory V3
Previous patch caused crash and had been reverted. This patch
addresses the issue without regression.

[Why]
1. Driver use umachannelnumber to calculate watermarks for stutter.
In asymmetric memory config, the actual bandwidth is less than
dual-channel. The bandwidth should be the same as single-channel.
2. We found single rank dimm need additional delay time for stutter.

[How]
Get information from each DIMM. Treat memory config as a single-channel
for asymmetric memory in bandwidth calculating.
Add additional delay time for single rank dimm.

c31bef1cb1 drm/amd/display: Fix clock table filling logic
[Why]
Currently, the code that fills the clock table can miss filling
information about some of the higher voltage states advertised
by the SMU. This, in turn, may cause some of the higher pixel clock
modes (e.g. 8k60) to fail validation.

[How]
Fill the table with one entry per DCFCLK level instead of one entry
per FCLK level. This is needed because the maximum FCLK does not
necessarily need maximum voltage, whereas DCFCLK values from SMU
cover the full voltage range.

[WHY]
To process AUX transactions with DMUB using inbox1 and outbox1 mail boxes.

[How]
1) Added inbox1 command DMUB_CMD__DP_AUX_ACCESS to issue AUX commands
   to DMUB in dc_process_dmub_aux_transfer_async(). DMUB processes AUX cmd
   with DCN and sends reply back in an outbox1 message triggering an
   outbox1 interrupt to driver.
2) In existing driver implementation, AUX commands are processed
   synchronously by configuring DCN reg. But in DMUB AUX, driver sends an
   inbox1 message and waits for a conditional variable (CV) which will be
   signaled by outbox1 ISR.
3) DM will retrieve Outbox1 message and send back reply to upper layer
   and complete the AUX command

[Why]
In gpu reset dc_lock acquired in dm_suspend().
Asynchronously handle_hpd_rx_irq can also be called
through amdgpu_dm_irq_suspend->flush_work, which also
tries to acquire dc_lock. That causes a deadlock.

ddab8bd788 drm/amd/display: Fix two cursor duplication when using overlay
Our driver supports overlay planes, and as expected, some userspace
compositor takes advantage of these features. If the userspace is not
enabling the cursor, they can use multiple planes as they please.
Nevertheless, we start to have constraints when userspace tries to
enable hardware cursor with various planes. Basically, we cannot draw
the cursor at the same size and position on two separated pipes since it
uses extra bandwidth and DML only run with one cursor.

For those reasons, when we enable hardware cursor and multiple planes,
our driver should accept variations like the ones described below:

  +-------------+   +--------------+
  | +---------+ |   |              |
  | |Primary  | |   | Primary      |
  | |         | |   | Overlay      |
  | +---------+ |   |              |
  |Overlay      |   |              |
  +-------------+   +--------------+

In this scenario, we can have the desktop UI in the overlay and some
other framebuffer attached to the primary plane (e.g., video). However,
userspace needs to obey some rules and avoid scenarios like the ones
described below (when enabling hw cursor):

                                      +--------+
                                      |Overlay |
 +-------------+    +-----+-------+ +-|        |--+
 | +--------+  | +--------+       | | +--------+  |
 | |Overlay |  | |Overlay |       | |             |
 | |        |  | |        |       | |             |
 | +--------+  | +--------+       | |             |
 | Primary     |    | Primary     | | Primary     |
 +-------------+    +-------------+ +-------------+

 +-------------+   +-------------+
 |     +--------+  |  Primary    |
 |     |Overlay |  |             |
 |     |        |  |             |
 |     +--------+  | +--------+  |
 | Primary     |   | |Overlay |  |
 +-------------+   +-|        |--+
                     +--------+

If the userspace violates some of the above scenarios, our driver needs
to reject the commit; otherwise, we can have unexpected behavior. Since
we don't have a proper driver validation for the above case, we can see
some problems like a duplicate cursor in applications that use multiple
planes. This commit fixes the cursor issue and others by adding adequate
verification for multiple planes.

Change since V1 (Harry and Sean):
- Remove cursor verification from the equation.

98025a62cb drm/dp_mst: Use Extended Base Receiver Capability DPCD space
[why]
DP 1.4a spec mandates that if DP_EXTENDED_RECEIVER_CAP_FIELD_PRESENT is
set, Extended Base Receiver Capability DPCD space must be used. Without
doing that, the three DPCD values that differ will be wrong, leading to
incorrect or limited functionality. MST link rate, for example, could
have a lower value. Also, Synaptics quirk wouldn't work out well when
Extended DPCD was not read, resulting in no DSC for such hubs.

[how]
Modify MST topology manager to use the values from Extended DPCD where
applicable.

To prevent regression on the sources that have a lower maximum link rate
capability than MAX_LINK_RATE from Extended DPCD, have the drivers
supply maximum lane count and rate at initialization time.

This also reverts commit 2dcab875e7 ("Revert drm/dp_mst: Retrieve
extended DPCD caps for topology manager"), brining the change back to the
original commit ad44c03208 ("drm/dp_mst: Retrieve extended DPCD caps for

6cba3fe433 drm/dp: Add backpointer to drm_device in drm_dp_aux
This is something that we've wanted for a while now: the ability to
actually look up the respective drm_device for a given drm_dp_aux struct.
This will also allow us to transition over to using the drm_dbg_*() helpers
for debug message printing, as we'll finally have a drm_device to reference
for doing so.

Note that there is one limitation with this - because some DP AUX adapters
exist as platform devices which are initialized independently of their
respective DRM devices, one cannot rely on drm_dp_aux->drm_dev to always be
non-NULL until drm_dp_aux_register() has been called. We make sure to point
this out in the documentation for struct drm_dp_aux.

v3:
* Add WARN_ON_ONCE() to drm_dp_aux_register() if drm_dev isn't filled out

c6c6a71219 drm/amd/display: Reject non-zero src_y and src_x for video planes
[Why]
This hasn't been well tested and leads to complete system hangs on DCN1

The system hang can be reproduced by gesturing the video on the YouTube

[How]
Reject atomic commits with non-zero drm_plane_state.src_x or src_y values.

v2:
 - Add code comment describing the reason we're rejecting non-zero
   src_x and src_y
 - Drop gerrit Change-Id
 - Add stable CC
 - Based on amd-staging-drm-next

[Why]
1. Driver use umachannelnumber to calculate watermarks for stutter.
In asymmetric memory config, the actual bandwidth is less than
dual-channel. The bandwidth should be the same as single-channel.
2. We found single rank dimm need additional delay time for stutter.

41efcd3879 drm/amd/display: Add MST capability to trigger_hotplug interface
[Why]
Need to be able to trigger software hotplug for MST connectors

[How]
For unplug the driver calls to disable topologies manager
that connector is attached to. For plugging in it does the
whole rediscovery of all connectors in drm device and enbles their
topologies if attached.

The interface for MST connectors works in the following way:

1. To disconnect all MST topologies currently connected:
   echo 0 > /sys/kernel/debug/dri/0/amdgpu_dm_trigger_hpd_mst

2. To reconnect/rediscover all topologies that are physically
connected to the card:
   echo 1 > /sys/kernel/debug/dri/0/amdgpu_dm_trigger_hpd_mst

Today a parameter is passed to dmub_srv_send_gpint_command

to be acked.
This parameter instead specifies the number of times to check if
the command was acked.
We wish to add a lower bound to the timeout, which can be
accomplished by using a delay or a timestamp.
It has been decided to use udelay instead of a timestamp simply
because we don't want to expose a high precision counter if it
doesn't yield large benefits.

cb2318b7c9 drm/amd/display: Use pr_debug in DM to prevent dmesg flooding
[why]
Our CI enables drm.debug=0x4 logs and the dmesg is flooded with cursor
updates. We probably want to avoid spamming the log with DRM_DEBUG_KMS.

[how]
Define and use pr_debug macros instead of a few spammy DRM_DEBUG_*'s.

68eb3ae3c6 drm/amd/display: Try YCbCr420 color when YCbCr444 fails
When encoder validation of a display mode fails, retry with less bandwidth
heavy YCbCr420 color mode, if available. This enables some HDMI 1.4 setups
to support 4k60Hz output, which previously failed silently.

On some setups, while the monitor and the gpu support display modes with
pixel clocks of up to 600MHz, the link encoder might not. This prevents
YCbCr444 and RGB encoding for 4k60Hz, but YCbCr420 encoding might still be
possible. However, which color mode is used is decided before the link
encoder capabilities are checked. This patch fixes the problem by retrying
to find a display mode with YCbCr420 enforced and using it, if it is
valid.

Due to the change how timing parameters were set, scaled modes would
cause a black screen on some eDP panels. Would probably apply to
other displays (i.e. even non-eDP) that only have scaled modes,
but such case is not that usual for external displays.

7df4ceb60f drm/amd/display: check fb of primary plane
Sometimes the primary plane might not be initialized (yet), which
causes dm_check_crtc_cursor to divide by zero.
Apparently a weird state before a S3-suspend causes the aforementioned
divide-by-zero error when resuming from S3.  This was explained in
bug 212293 on Bugzilla.

To avoid this divide-by-zero error we check if the primary plane's fb
isn't NULL.  If it's NULL the src_w and src_h attributes will be 0,
which would cause a divide-by-zero.

This fixes Bugzilla report 212293

dm_plane_format_mod_supported which is extended to validate that the
modifier is on the list of the plane's supported modifiers.

The bug was caught using igt-gpu-tools test: kms_addfb_basic.addfb25-bad-modifier

Tested on ChromeOS Zork by turning on the display, running an overlay
test, and running a YT video.

=== Changes from v1 ===
Explicitly handle DRM_FORMAT_MOD_INVALID modifier.

54718747a6 drm/amd/display: Fix UBSAN: shift-out-of-bounds warning
[Why]
On NAVI14 CONFIG_UBSAN reported shift-out-of-bounds at
display_rq_dlg_calc_20v2.c:304:38

rq_param->misc.rq_c.blk256_height is 0 when chroma(*_c) is invalid.
dml_log2 returns -1023 for log2(0), although log2(0) is undefined.

Which ended up as:
rq_param->dlg.rq_c.swath_height = 1 << -1023

[How]
Fix applied on all dml versions.
1. Ensure dml_log2 is only called if the argument is greater than 0.
2. Subtract req128_l/req128_c from log2_swath_height_l/log2_swath_height_c
   only when it is greater than 0.

d1fa156809 drm/amd/display: Support vertical interrupt 0 for all dcn ASIC
[Why]
When CONFIG_DRM_AMD_SECURE_DISPLAY is enabled, it will try
to register vertical interrupt 0 for specific task.

Currently, only dcn10 have defined relevant info for vertical interrupt
0. If we enable CONFIG_DRM_AMD_SECURE_DISPLAY for other dcn ASIC, will
get DC_IRQ_SOURCE_INVALID while calling dc_interrupt_to_irq_source() and
cause pointer errors.

[Why]
Find out that when we are registering vertical interrupt0, we get
DC_IRQ_SOURCE_INVALID when call dc_interrupt_to_irq_source for
DCN_1_0__SRCID__OTG6_VERTICAL_INTERRUPT0_CONTROL.

After analyzing, it's due to the defined value for
DCN_1_0__SRCID__OTG6_VERTICAL_INTERRUPT0_CONTROL is not
(DCN_1_0__SRCID__OTG5_VERTICAL_INTERRUPT0_CONTROL + 1). It's not
incremental sequence.

[How]
Use an array to record all vertical interrupt0 SRCID. While registering
interrupt, use an incremental index to visit the array to get the right
SRCID to register.

1c5ea40c2a drm/amd/display: add a func to disable accelerated mode
[Why]
When driver disabled, we driver force the YCbCr420 to RGB,
which means some register will be changed, such as
RDPCS_PHY_DP_MPLLB_TX_CLK_DIV changed from 1 to 0
When driver re-enabled, OS will Set Mode YCbCr420 again,
which means the register RDPCS_PHY_DP_MPLLB_TX_CLK_DIV
should to be 1 again, but dmub fw can’t update the
register to 1 due to the mpll is not off

[How]
Adds an interface to disable accelerated mode bit,
which allows DM to decide to call during driver
disable/unload scenarios.

cd95ef0097 drm/amd/display: Fix secure display lock problems
[Why]
Find out few locks problems while doing secure display. They are
following few parts:

1. crc_rd_work_lock in amdgpu_dm_crtc_handle_crc_window_irq() should
also use spin_lock_irqsave instead of spin_lock_irq.

2. In crc_win_update_set(), crc_rd_work_lock should be grabbed after
obtaining lock event_lock. Otherwise, will cause deadlock by conflicting
the lock order in amdgpu_dm_crtc_handle_crc_window_irq()

3. flush_work() in crc_win_update_set() is no need and will cause
deadlock since amdgpu_dm_crtc_notify_ta_to_read() also tries to grab
lock crc_rd_work_lock.

[How]
Fix above problems.

0dd7953234 drm/amdgpu/display: Implement functions to let DC allocate GPU memory
[Why]
DC needs to communicate with PM FW through GPU memory. In order
to do so we need to be able to allocate memory from within DC.

[How]
Call amdgpu_bo_create_kernel to allocate GPU memory and use a
list in amdgpu_display_manager to track our allocations so we
can clean them up later.

554ba183b1 drm/amd/display: Align cursor cache address to 2KB
[Why]
The registers for the address of the cursor are aligned to 2KB, so all
cursor surfaces also need to be aligned to 2KB. Currently, the
provided cursor cache surface is not aligned, so we need a workaround
until alignment is enforced by the surface provider.

[How]
 - round up surface address to nearest multiple of 2048
 - current policy is to provide a much bigger cache size than
   necessary,so this operation is safe

15e8b95d5f drm/amd/display: Fix nested FPU context in dcn21_validate_bandwidth()
Commit 41401ac677 added FPU wrappers to dcn21_validate_bandwidth(),
which was correct. Unfortunately a nested function alredy contained
DC_FP_START()/DC_FP_END() calls, which results in nested FPU context
enter/exit and complaints by kernel_fpu_begin_mask().
This can be observed e.g. with 5.10.20, which backported 41401ac677
and now emits the following warning on boot:

WARNING: CPU: 6 PID: 858 at arch/x86/kernel/fpu/core.c:129 kernel_fpu_begin_mask+0xa5/0xc0
Call Trace:
 dcn21_calculate_wm+0x47/0xa90 [amdgpu]

 dcn21_validate_bandwidth+0x29/0x40 [amdgpu]
 dc_validate_global_state+0x3c7/0x4c0 [amdgpu]

The warning is emitted due to the additional DC_FP_START/END calls in
patch_bounding_box(), which is inlined into dcn21_calculate_wm(),
its only caller. Removing the calls brings the code in line with
dcn20 and makes the warning disappear.

7c20984795 drm/amd/display: Add a backlight module option
There seem devices that don't work with the aux channel backlight
control.  For allowing such users to test with the other backlight
control method, provide a new module option, aux_backlight, to specify
enabling or disabling the aux backport support explicitly.  As
default, the aux support is detected by the hardware capability.

v2: make the backlight option generic in case we add future
backlight types (Alex)

8e6fafd5a2 drm/amd/display: Fix off by one in hdmi_14_process_transaction()
The hdcp_i2c_offsets[] array did not have an entry for
HDCP_MESSAGE_ID_WRITE_CONTENT_STREAM_TYPE so it led to an off by one
read overflow.  I added an entry and copied the 0x0 value for the offset
from similar code in drivers/gpu/drm/amd/display/modules/hdcp/hdcp_ddc.c.

I also declared several of these arrays as having HDCP_MESSAGE_ID_MAX
entries.  This doesn't change the code, but it's just a belt and
suspenders approach to try future proof the code.

array index:

drivers/gpu/drm/amd/amdgpu/../display/amdgpu_dm/amdgpu_dm.c:9720:7: note: initialize the variable 'i' to silence this warning

My best guess is that the index should have been returned by the
parse_hdmi_amd_vsdb() function that walks an array here, so do that.
