584bdbca91 drm/bridge: tc358768: select CONFIG_VIDEOMODE_HELPERS
[ Upstream commit 2651330097 ]

A dependency on this feature was recently introduced:

x86_64-linux-ld: vmlinux.o: in function `tc358768_bridge_pre_enable':
tc358768.c:(.text+0xbe3dae): undefined reference to `drm_display_mode_to_videomode'

Make sure this is always enabled.

45d72eadf2 drm/amdkfd: get doorbell's absolute offset based on the db_size
[ Upstream commit 367a0af433 ]

Here, Adding db_size in byte to find the doorbell's
absolute offset for both 32-bit and 64-bit doorbell sizes.
So that doorbell offset will be aligned based on the doorbell
size.

v2:
- Addressed the review comment from Felix.
v3:
- Adding doorbell_size as parameter to get db absolute offset.
v4:
  Squash the two patches into one.

915864d186 drm/amdgpu: correct chunk_ptr to a pointer to chunk.
[ Upstream commit 50d51374b4 ]

The variable "chunk_ptr" should be a pointer pointing
to a struct drm_amdgpu_cs_chunk instead of to a pointer
of that.

117917b0be drm/amd/display: Fix MPCC 1DLUT programming
[ Upstream commit 6f395cebdd ]

[Why]
Wrong function is used to translate LUT values to HW format, leading to
visible artifacting in some cases.

[How]
Use the correct cm3_helper function.

d05614ebad drm/amd/display: Simplify brightness initialization
[ Upstream commit d9e865826c ]

[Why]
Remove the brightness cache in DC. It uses a single value to represent
the brightness for both SDR and HDR mode. This leads to flash in HDR
on/off. It also unconditionally programs brightness as in HDR mode. This
may introduce garbage on SDR mode in miniLED panel.

[How]
Simplify the initialization flow by removing the DC cache and taking
what panel has as default. Expand the mechanism for PWM to DPCD Aux to
restore cached brightness value generally.

86cd446a77 drm/amd/display: Reduce default backlight min from 5 nits to 1 nits

[Why & How]
Currently set_default_brightness_aux function uses 5 nits as lower limit

d03960b483 drm/i915/gsc: Mark internal GSC engine with reserved uabi class
[ Upstream commit 503579448d ]

The GSC CS is not exposed to the user, so we skipped assigning a uabi
class number for it. However, the trace logs use the uabi class and
instance to identify the engine, so leaving uabi class unset makes the
GSC CS show up as the RCS in those logs.

Given that the engine is not exposed to the user, we can't add a new
case in the uabi enum, so we insted internally define a kernel
internal class as -1.

At the same time remove special handling for the name and complete
the uabi_classes array so internal class is automatically correctly
assigned.

Engine will show as 65535:0 other0 in the logs/traces which should
be unique enough.

v2:
 * Fix uabi class u8 vs u16 type confusion.

commit b9f46f0b98 upstream.

On recent versions of DMUB firmware, if we want to completely disable
ABM we have to pass ABM_LEVEL_IMMEDIATE_DISABLE as the requested ABM
level to DMUB. Otherwise, LCD eDP displays are unable to reach their
maximum brightness levels. So, to fix this whenever the user requests an
ABM level of 0 pass ABM_LEVEL_IMMEDIATE_DISABLE to DMUB instead. Also,
to keep the user's experience consistent map ABM_LEVEL_IMMEDIATE_DISABLE
to 0 when a user tries to read the requested ABM level.

517e1355bb drm/i915: Also check for VGA converter in eDP probe
commit f76f83a83c upstream.

Unfortunately even the HPD based detection added in
commit cfe5bdfb27 ("drm/i915: Check HPD live state during eDP probe")
fails to detect that the VBT's eDP/DDI-A is a ghost on
Asus B360M-A (CFL+CNP). On that board eDP/DDI-A has its HPD
asserted despite nothing being actually connected there :(
The straps/fuses also indicate that the eDP port is present.

So if one boots with a VGA monitor connected the eDP probe will
mistake the DP->VGA converter hooked to DDI-E for an eDP panel
on DDI-A.

As a last resort check what kind of DP device we've detected,
and if it looks like a DP->VGA converter then conclude that
the eDP port should be ignored.

Many user-space compositors fail with mode setting if a CRTC has
more than one connected connector. This is the case with the BMC
on Aspeed systems. Work around this problem by setting the BMC's
connector status to disconnected when the physical connector has
a display attached. This way compositors will only see one connected

405b4f6d21 drm/msm/dpu: Add missing safe_lut_tbl in sc8280xp catalog
commit a33b2431d1 upstream.

During USB transfers on the SC8280XP __arm_smmu_tlb_sync() is seen to
typically take 1-2ms to complete. As expected this results in poor
performance, something that has been mitigated by proposing running the
iommu in non-strict mode (boot with iommu.strict=0).

This turns out to be related to the SAFE logic, and programming the QOS
SAFE values in the DPU (per suggestion from Rob and Doug) reduces the
TLB sync time to below 10us, which means significant less time spent
with interrupts disabled and a significant boost in throughput.

d75f7c1bd8 drm/panel: boe-tv101wum-nl6: Fine tune Himax83102-j02 panel HFP and HBP
[ Upstream commit cea7008190 ]

The refresh reported by modetest is 60.46Hz, and the actual measurement
is 60.01Hz, which is outside the expected tolerance. Adjust hporch and
pixel clock to fix it. After repair, modetest and actual measurement were
all 60.01Hz.

Modetest refresh = Pixel CLK/ htotal* vtotal, but measurement frame rate
is HS->LP cycle time(Vblanking). Measured frame rate is not only affecte
by Htotal/Vtotal/pixel clock, also affected by Lane-num/PixelBit/LineTime
/DSI CLK. Assume that the DSI controller could not make the mode that we
requested(presumably it's PLL couldn't generate the exact pixel clock?).
If you use a different DSI controller, you may need to readjust these
parameters. Now this panel looks like it's only used by me on the MTK
platform, so let's change this set of parameters.

1911b120d4 drm/i915: do not clean GT table on error path
[ Upstream commit 0561794b6b ]

The only task of intel_gt_release_all is to zero gt table. Calling
it on error path prevents intel_gt_driver_late_release_all (called from
i915_driver_late_release) to cleanup GTs, causing leakage.
After i915_driver_late_release GT array is not used anymore so
it does not need cleaning at all.

Sample leak report:

BUG i915_request (...): Objects remaining in i915_request on __kmem_cache_shutdown()
...
Object 0xffff888113420040 @offset=64
Allocated in __i915_request_create+0x75/0x610 [i915] age=18339 cpu=1 pid=1454

d6569fecd6 drm/panel: simple: Fix Innolux G101ICE-L01 timings
[ Upstream commit 3f9a91b6c0 ]

The Innolux G101ICE-L01 datasheet [1] page 17 table
6.1 INPUT SIGNAL TIMING SPECIFICATIONS
indicates that maximum vertical blanking time is 40 lines.
Currently the driver uses 29 lines.

Fix it, and since this panel is a DE panel, adjust the timings
to make them less hostile to controllers which cannot do 1 px
HSA/VSA, distribute the delays evenly between all three parts.

17661e606e drm/amd/display: Change the DMCUB mailbox memory location from FB to inbox
commit 5911d02cac upstream.

[WHY]
Flush command sent to DMCUB spends more time for execution on
a dGPU than on an APU. This causes cursor lag when using high
refresh rate mouses.

[HOW]
1. Change the DMCUB mailbox memory location from FB to inbox.
2. Only change windows memory to inbox.

a4a131bdd9 drm/amd/display: Clear dpcd_sink_ext_caps if not set
commit 923bbfe6c8 upstream.

[WHY]
Some eDP panels' ext caps don't set initial values
and the value of dpcd_addr (0x317) is random.
It means that sometimes the eDP can be OLED, miniLED and etc,
and cause incorrect backlight control interface.

[HOW]
Add remove_sink_ext_caps to remove sink ext caps (HDR, OLED and etc)

commit b71f4ade1b upstream.

When ddc_service_construct() is called, it explicitly checks both the
link type and whether there is something on the link which will
dictate whether the pin is marked as hw_supported.

If the pin isn't set or the link is not set (such as from
unloading/reloading amdgpu in an IGT test) then fail the
amdgpu_dm_i2c_xfer() call.
