On DCE8-class ASICs (e.g. Bonaire), the resource pool contains digital
DIG stream encoders plus one analog DAC encoder. When assigning a stream
encoder for a second DisplayPort MST stream, if the preferred digital
encoder is already acquired, dce100_find_first_free_match_stream_enc_for_link()
falls back to the first free pool entry. That entry may be the analog
encoder, whose funcs table lacks DP hooks such as dp_set_stream_attribute.
The subsequent atomic commit then dereferences NULL function pointers in
link_set_dpms_on() and crashes.
Skip encoders without dp_set_stream_attribute when the stream uses a DP
signal (including MST). Use dc_is_dp_signal(stream->signal) for the MST
fallback path instead of checking only the link connector signal.
Tested on:
- GPU: AMD Radeon R7 260X (Bonaire / DCE8)
- Board: Supermicro C9X299-PG300
- Setup: DP MST daisy chain, hotplug second monitor or have it connected on boot
- Kernel: 7.1.3 (issue observed since 6.19)
- Result: kernel oops without patch; dual monitors stable with patch

The old radeon driver has a documented workaround in ci_dpm.c
which claims that Bonaire 0x6658 with old memory controller
firmware is unstable with MCLK DPM, so as a precaution I
disabled MCLK DPM on this ASIC in amdgpu.
Note that the old MC firmware is not actually used with
amdgpu, but in theory it's possible that the VBIOS sets
up the ASIC with an old MC firmware that is already running
when amdgpu initializes (in which case amdgpu doesn't
load its own firmware).
What I expected to happen is that the GPU would simply use
its maximum memory clock, and indeed this is what seemed
to happen according to amdgpu_pm_info which reads the
current MCLK value from the SMU.
However, some users reported a huge perf regression
and upon a closer look it seems that the GPU seems to
not actually use the highest MCLK value, despite the SMU
reporting that it does.
Let's not disable MCLK DPM on Bonaire 0x6658 (R7 260X).
Keep MCLK DPM disabled on R9 M380 in the 2015 iMac
because that still hangs if we enable it.

When compiling the AMDGPU display driver for 32-bit architectures,
the linker reports undefined reference to `__udivdi3` in functions
get_dp_dto_frequency_100hz() and dcn401_get_dp_dto_frequency_100hz().
This is because the code uses 64-bit division (/) on 32-bit systems,
which GCC cannot handle directly and instead tries to call the missing
__udivdi3 helper function.
Replace the raw division with div_u64(), the kernel's standard 64-bit
division helper, to avoid the link error.

amdgpu_acpi_vfct_bios() fetches the VFCT table with acpi_get_table()
but never releases it. acpi_get_table() takes a reference on the
table (incrementing its validation_count and mapping it on the 0->1
transition); without a paired acpi_put_table() the mapping is leaked
on every call, whether or not a matching VBIOS image is found.
Route all exit paths after the table is acquired through a common
acpi_put_table(). The VBIOS image is copied out with kmemdup() before
the table is released, so it remains valid for the caller.

On systems where PCI bus renumbering occurs (e.g. pci=realloc,
resource conflicts), the runtime bus number may differ from the
BIOS POST bus number recorded in the VFCT table. This causes
amdgpu_acpi_vfct_bios() to fail finding the VBIOS even though
the correct device entry exists.
Introduce amdgpu_acpi_vfct_match() which treats the bus number
as a soft filter: vendor/device/function identity is the hard
requirement, while exact bus match is the preferred path. When
bus numbers disagree but device identity matches, accept the
VFCT entry and log a dev_notice for diagnostics.

amdgpu_bo_create_reserved() only allocates a new BO when
*bo_ptr (struct amdgpu_bo **bo_ptr as input parameter) is
NULL, it simply skips creation when *bo_ptr is non-NULL.
But it unconditionally reserves, pins, gart allocates
and maps the BO afterwards.
When the same non-NULL BO pointer is passed in again,
for example firmware buffers that live in adev and are
re-loaded on every resume / cp_resume / start
under AMDGPU_FW_LOAD_DIRECT, amdgpu_bo_pin() just increases
pin_count unconditionally, however the matching teardown only unpins
once, so pin_count never drops to zero, so TTM is not able
to move, swap or evict a BO, causing BO leaks.
This commit fixes this issue by only pinning the bo
once at creation, and repeated calls no longer
take additional pin references.

pre_reset only force-completes fences of MAPPED queues. A queue in any
other state (e.g. mid-eviction) keeps its last_fence pending; after a
GPU reset that fence never signals, so the eviction/suspend worker and
process teardown (amdgpu_evf_mgr_flush_suspend) wait on it forever and

[Why]
FWTS autobrightness fails on eDP panels because actual_brightness can
read higher than the advertised max_brightness (e.g. 63576 vs 62451).
The conversion helpers expose the firmware PWM range to userspace as
[0..max]. But max_brightness is advertised as (max - min), which is
smaller. So reading the level can return a value above max_brightness.
This regressed in commit 4b61b8a39051 ("drm/amd/display: Add debugging
message for brightness caps"), which changed max_brightness to
(max - min) and undid commit 8dbd72cb7900 ("drm/amd/display: Export full
brightness range to userspace").
[How]
Advertise max_brightness as max, and scale the initial AC/DC brightness
against max too. Update the KUnit expectations to match.

[why]
The 8K120/8K240 timings live in DisplayID extension blocks 2 and 3
of this EDID. The EDID is a 4-block (512-byte) HDMI 2.1 EDID
that uses HF-EEODB.
drm core reads and parses this correctly, but amdgpu rebuilds its own copy.
Only 2 of 4 blocks were copied into sink->dc_edid, that leads to
drm_edid_connector_add_modes() never sees blocks 2 and 3.

No functional changes. Just clean up a conceptual mismatch.
Based on feedback on the NUTMEG code in DC, the
preferred_link_setting is meant to force the DP link to a
specific setting, meaning both the link rate and lane count
should be locked to an exact value. What NUTMEG needs is
a lower bound on the link rate, which is not the same concept.
Implement this as a HW workaround flag instead.

Some AMD APU multi-function devices expose an integrated USB xHCI
controller. In some circumstances (such as larger VRAM), the PM core
can resume can fail when the xHCI controller is resuming in parallel
with the GPU/display function.
On affected systems, the xHCI controller can complete pci_pm_resume
and start resuming USB devices while the GPU is still in its much
longer resume path. This race condition leads to USB device resume
failures followed by:
xhci_hcd ...: xHCI host not responding to stop endpoint command
xhci_hcd ...: HC died; cleaning up
Create a device link from any xHCI controller sharing the same PCIe
root port as the APU display function. The link uses DL_FLAG_STATELESS
and DL_FLAG_PM_RUNTIME to ensure the GPU completes its resume before
the xHCI controller begins resuming USB devices.
This device link is done specifically in amdgpu so that if the
platform firmware has been modified such that this issue doesn't happen
the version can be detected and the workaround skipped.

DCN42B enables DML2 and DML21 by default and defines
dcn42b_prepare_mcache_programming(), but the resource function table only
wires the callback when CONFIG_DRM_AMD_DC_DML21 is defined.
There is no in-tree Kconfig symbol named DRM_AMD_DC_DML21, so the
preprocessor always removes the callback entry. Sibling DCN42 and DCN401
resource tables wire their prepare_mcache_programming callbacks
unconditionally, and the core DC code already checks whether the callback
pointer is present before calling it.
Remove the stale guard so DCN42B exposes the callback relation that its
source and DML21 build world already provide.
This is an RFC patch draft from static conditional callback legality
auditing. It needs AMD display maintainer review before submission as a

The Lenovo Legion 5 15ARH05 (Renoir) ships a BOE 0x08DF eDP panel that
advertises AUX/DPCD backlight control, so amdgpu's automatic detection
(amdgpu_backlight == -1) selects AUX. On this panel the AUX backlight
path has no effect: brightness writes are accepted but the panel level
never changes, the display is stuck at a fixed brightness and
max_brightness is reported as a bogus 511000. As a result neither the
desktop brightness slider nor the brightness hotkeys do anything.
Forcing PWM backlight (amdgpu.backlight=0) restores working control:
max_brightness becomes 65535 and the level tracks writes. This has long
been applied by users as a manual kernel-parameter workaround.
Extend the generic panel backlight quirk with a force_pwm flag, add an
entry for the Legion 5 15ARH05 / BOE 0x08DF panel, and have amdgpu
disable AUX backlight (use PWM) when the quirk matches and the user
lets the driver auto-select the backlight type.

The change referenced by the Fixes tag releases the HIQ SDMA MQD trunk
buffer when device_queue_manager_init() fails after it has been
allocated.
However, the same failure path can also be reached after
init_mqd_managers() has succeeded. At that point dqm->mqd_mgrs[] contains
per-type MQD manager objects owned by the device queue manager. The
normal teardown path frees those objects from uninitialize(), but the
initialization error path only frees dqm itself.
Free the MQD managers from the initialization error path as well. This is
safe for earlier failures because dqm is zeroed when allocated and
init_mqd_managers() clears the entries it rolls back internally.

amdgpu_dm_audio_eld_notify() is currently only called in atomic commits.
This results in the state of the HDA driver never getting updated when
an audio sink is removed and an atomic commit never comes. (eg the HDMI
audio jack switch in ALSA stays 'on' after the HDMI cable is
disconnected if no other display is connected to cause the compositor to
submit an atomic commit)
Call amdgpu_dm_audio_eld_notify() in
amdgpu_dm_update_connector_after_detect() when a sink is no longer
available to ensure that the HDA driver always gets notified on
disconnect regardless of atomic commits.

The XGMI reset-on-init path can run while the device is still at the
minimal init level, such as during an NPS memory partition switch. In
that flow the normal RAS IP block hw_init is skipped, so unified RAS
is not enabled when the early CPER initialization is attempted, leaving
CPER disabled for the rest of the device's lifetime.
Resume RAS after the XGMI reset-on-init completes. Once the RAS manager
resume succeeds, the RAS resume wrapper performs deferred CPER
initialization, keeping the path a no-op for devices where CPER was
already initialized.
Keep the deferred CPER retry and its debugfs registration together in
the CPER helper. The normal debugfs ring walk skips the CPER ring until
CPER is enabled, so the ring debugfs entry is created either by the
deferred helper when debugfs is already available or by the normal
debugfs walk.

There were two mistakes in the previous implementation:
The check for AutomaticDCTransition should be inverted.
We recently learned that the kernel should send
PPSMC_MSG_RunningOnAC when the flag is set, and not the
other way around.
The clocks also need to be recomputed, because the code in
the smu7_apply_state_adjust_rules() function selects
different limits on AC and DC.

We can't print the IP block name when the IP block is NULL.
Note that it should never be NULL, the only way that
can happen is when amdgpu_ip_from_ring() is missing the
given ring type. The check is just there to be sure.

Commit 055a40c32f3a ("drm/amd/pm: Use uploaded size for legacy custom
PPTable") changed pp_dpm_set_pp_table() to kmemdup the uploaded buffer
directly and set soft_pp_table_size to the uploaded size. As a result
soft_pp_table now points to an allocation completely outside adev->bios,
making the pp_end > bios_end check in pp_entries_max() likely true for
custom PP tables — returning 0 and breaking PP table overrides via sysfs.

- ppt_residency_acc
- socket_thm_residency_acc

- gfx_activity_acc
- mem_activity_acc
- pcie_nak_sent_count_acc
