During driver probe we might be briefly using CT safe mode, which
is based on a delayed work, but usually we are able to stop this
once we have IRQ fully operational. However, if we abort the probe
quite early then during unwind we might try to destroy the workqueue
while there is still a pending delayed work that attempts to restart
itself which triggers a WARN.
This was recently observed during unsuccessful VF initialization:
[ ] xe 0000:00:02.1: probe with driver xe failed with error -62

By default, HPD was disabled on SN65DSI86 bridge. When the driver was
added (commit "a095f15c00e27"), the HPD_DISABLE bit was set in pre-enable
call which was moved to other function calls subsequently.
Later on, commit "c312b0df3b13" added detect utility for DP mode. But with
HPD_DISABLE bit set, all the HPD events are disabled[0] and the debounced
state always return 1 (always connected state).
Set HPD_DISABLE bit conditionally based on display sink's connector type.
Since the HPD_STATE is reflected correctly only after waiting for debounce
time (~100-400ms) and adding this delay in detect() is not feasible
owing to the performace impact (glitches and frame drop), remove runtime
calls in detect() and add hpd_enable()/disable() bridge hooks with runtime
calls, to detect hpd properly without any delay.

As I understand it, the problem is that the function is not always fully
inlined, but the __builtin_constant_p() can still evaluate the argument
as being constant.
Marking it as __always_inline so far works for me in all configurations.

When EDID is retrieved via drm_edid_raw(), it doesn't guarantee to
return proper EDID bytes the caller wants: it may be either NULL (that
leads to an Oops) or with too long bytes over the fixed size raw_edid
array (that may lead to memory corruption). The latter was reported
actually when connected with a bad adapter.
Add sanity checks for drm_edid_raw() to address the above corner
cases, and return EDID_BAD_INPUT accordingly.

missed updating AMDGPU_MAX_BL_LEVEL which is needed to make sure that
scaling works properly with custom brightness curves.

Enable the cleaner shader for other GFX9.x series of GPUs to provide
data isolation between GPU workloads. The cleaner shader is responsible
for clearing the Local Data Store (LDS), Vector General Purpose
Registers (VGPRs), and Scalar General Purpose Registers (SGPRs), which
helps prevent data leakage and ensures accurate computation results.
This update extends cleaner shader support to GFX9.x GPUs, previously
available for GFX9.4.2. It enhances security by clearing GPU memory
between processes and maintains a consistent GPU state across KGD and
KFD workloads.

Reading DPCD registers has side-effects in general. In particular
accessing registers outside of the link training register range
(0x102-0x106, 0x202-0x207, 0x200c-0x200f, 0x2216) is explicitly
forbidden by the DP v2.1 Standard, see
3.6.5.1 DPTX AUX Transaction Handling Mandates
3.6.7.4 128b/132b DP Link Layer LTTPR Link Training Mandates
Based on my tests, accessing the DPCD_REV register during the link
training of an UHBR TBT DP tunnel sink leads to link training failures.
Solve the above by using the DP_LANE0_1_STATUS (0x202) register for the
DPCD register access quirk.

DIV_ROUND_CLOSEST_ULL uses do_div(), which expects a 32-bit divisor.
When passing a 64-bit constant like CURVE2_MULTIPLIER, the value is
silently truncated to u32, potentially leading to incorrect results

Replace DIV_ROUND_CLOSEST_ULL with DIV64_U64_ROUND_CLOSEST which correctly
handles full 64-bit division.

The drm_writeback_connector_cleanup have the signature:
static void drm_writeback_connector_cleanup(
struct drm_device *dev,
struct drm_writeback_connector *wb_connector)
But it is stored and used as a drmres_release_t
typedef void (*drmres_release_t)(struct drm_device *dev, void *res);
While the current code is valid and does not produce any warning, the
CFI runtime check (CONFIG_CFI_CLANG) can fail because the function
signature is not the same as drmres_release_t.
In order to fix this, change the function signature to match what is
expected by drmres_release_t.

programmed from 0-0xFFFF. This can be limiting to some software
that wants to apply greater granularity.
[HOW]
Convert internally to firmware values only when mapping custom
brightness curves because these are in 0-0xFF range. Advertise full
PWM range to userspace.

[WHY]
Backlight caps are read already in amdgpu_dm_update_backlight_caps().
They may be updated by update_connector_ext_caps(). Reading again when
registering backlight device may cause wrong values to be used.
[HOW]
Use backlight caps already registered to the dm.

[WHY]
For non-zero DSC instances it's possible that the HUBP domain required
to drive it for sequential ONO ASICs isn't met, potentially causing
the logic to the tile to enter an undefined state leading to a system
hang.
[HOW]
Add more checks to ensure that the HUBP domain matching the DSC instance
is appropriately powered.

(cherry picked from commit da63df0711)
Cc: stable@vger.kernel.org
[WHY]
These fields are read for the explicit purpose of detecting embedded LTTPRs
(i.e. between host ASIC and the user-facing port), and thus need to
calculate the correct DPCD address offset based on LTTPR count to target
the appropriate LTTPR's DPCD register space with these queries.
[HOW]
Cascaded LTTPRs in a link each snoop and increment LTTPR count when queried
via DPCD read, so an LTTPR embedded in a source device (e.g. USB4 port on a
laptop) will always be addressible using the max LTTPR count seen by the
host. Therefore we simply need to use a recently added helper function to
calculate the correct DPCD address to target potentially embedded LTTPRs
based on the received LTTPR count.

Fixes for v6.16-rc3
Display:
- Fixed DP output on SDM845
- Fixed 10nm DSI PLL init
GPU:
- SUBMIT ioctl error path leak fixes
- drm half of stall-on-fault fixes. Note there is a soft dependency,
to get correct mmu fault devcoredumps, on arm-smmu changes which
are not in this branch, but have already been merged by Linus. So
by the time Linus merges this, everything should be peachy.
- a7xx: Missing CP_RESET_CONTEXT_STATE
- Skip GPU component bind if GPU is not in the device table.
