The IRQ handler disables the IRQ and schedules irq_work. Releasing the
IRQ does not drain that work, which can continue to use the devm-allocated
chip and notifier state.
Manage both IRQ-work cancellation and subdevice removal with devres.
Register the subdevice-removal action before requesting the IRQ, then add
the IRQ-work action after the request. This avoids leaving a live IRQ
without work cancellation if action registration fails. Devres cleanup
then disables the IRQ and drains the work before releasing the IRQ and
removing child devices. Register both actions before creating the children
so partial probe failures use the same ordering.
This issue was found by the author's in-house static analysis tool.
The patch was reviewed by the author against the latest mainline tree.

When the commit b67d2d039f64 ("drm/gem: Add callback for when handle
count goes to 0") added the handle_free callback, it did not update the
rust abstraction, which will cause a build failure when that is enabled.
Rather than just adding another None initializer, use
..pin_init::zeroed() to make all unlisted callbacks None, and remove the
existing zero-initializations.

When building with -Wincompatible-function-pointer-types-strict, a

resource_build_info_frame() derives colorimetry and RGB quantization from
stream->output_color_space. A Broadcast RGB-only atomic commit updates
that field and reprograms the output CSC, but none of the InfoFrame update
predicates include output_color_space. The sink can therefore retain the
previous AVI InfoFrame range while the source starts transmitting a
different pixel range.
Treat an output color space change as an InfoFrame change in update
classification and in both stream programming paths.
Hardware testing on an HDMI 2.1 television confirmed that its automatic
black-level selection follows Full to Limited and Limited to Full
transitions in SDR, HDR, and HDR with VRR active, without a modeset or

amdgpu_dm_get_output_color_space() applies the Broadcast RGB connector
property to default RGB output, but always selects full-range output for
BT.2020 RGB. Consequently, explicitly selecting Limited has no effect on
the output CSC or AVI InfoFrame when HDR uses BT.2020 RGB.
Select COLOR_SPACE_2020_RGB_LIMITEDRANGE when the output encoding is RGB
and Broadcast RGB is Limited. Keep Automatic and Full at full range, and
leave YCbCr output unchanged.
Add KUnit coverage for limited-range RGB output through both BT.2020
connector colorspace values.

DC uses dc_edid_caps.qs_bit when constructing the HDMI AVI InfoFrame
quantization-range field. Although DRM parses the sink capability into
drm_display_info, DM never copies it into the DC EDID capabilities. The
field therefore remains zero and the AVI quantization range stays at its
default value.

EDID-capability KUnit test to cover it.

On the LSDMA path amdgpu_ualink_send_command() ignored the return of
amdgpu_lsdma_copy_mem() and polled the remote completion for the full

send in amdgpu_ualink_exp_cleanup_worker() wasted ~2s, and the peer

A hung SDMA user queue wedges MES, so the MES packet reset times out and
falls back to a full MODE1 reset - once per in-flight job, a reset storm.
The queue is still on its HW slot at the first hang-detect, so use
detect_hung_queue to recover its slot from the doorbell and reset it over
MMIO, which does not need MES. Mark it HUNG (not UNMAPPED) so the restore
worker does not re-map and re-run the guilty job, and short-circuit the

which some compilers diagnose and which obscures the intent of the

Add tests for cleanup after a batched RTM_NEWACTION request fails.
Replace an existing gact action bound to a filter, then fail a later
entry by requesting goto chain without a classifier context.
Check that the bound action's reference count returns to its original
value. Also cover a successfully initialized new action between the
bound action and the failing entry, verifying that its reserved index
can be reused. Repeat the bound action in another batch to check that
each temporary reference to the same action is released.

When a batched RTM_NEWACTION request replaces an existing action,
tcf_idr_check_alloc() takes a temporary reference on it. If a later
action fails to initialize, tcf_action_destroy() uses strict release
semantics to clean up the actions initialized so far. For an action
bound to a filter, the strict check returns -EPERM without dropping
the temporary reference.
This error also makes tcf_action_destroy() return before releasing
subsequent entries. Any new action initialized between the bound
action and the failing entry is leaked together with its reserved
IDR slot, preventing reuse of its index.
Use tcf_idr_release() to drop each reference held by the batch without
rejecting bound actions. This allows cleanup to continue through all
initialized entries and preserves the module reference release when
an action is destroyed. Explicit action deletion and flushing retain
their separate bind-count checks.

[Why & How]
Add dm_test_irq_handler_invalid_source to cover the early return in
amdgpu_dm_irq_handler() when dc_interrupt_to_irq_source() cannot map the
hardware entry.
Reuse the existing unmapped irq_service stub and assert that neither the
high- nor the low-context handler is dispatched.

[Why]
dc_interrupt_to_irq_source() can return DC_IRQ_SOURCE_INVALID for an
unmapped src_id/src_data pair. The value was passed straight to
dc_interrupt_ack() and used to index the DM high/low handler tables.
[How]
Reject sources outside the valid range before using them.

[Why & How]
- Dumping clock registers in SW init can get incorrect clock readback due
to other init code (e.g., in DMU) potentially not executed yet
- Move clk_ip register access into HW init to ensure the clock read back
gets the correct values

[Why & How]
dcn6_calculate_flip_schedule() no longer uses meta_row_height and
meta_row_height_chroma in any of its calculations, so both parameters
are flagged as unreferenced by compilers with stricter warning levels.
Cast both to void to document that they are intentionally unused. The
parameters are kept because the signature is fixed by the
shared function pointer.

[Why & How]
The HDMI Forum VSDB reports the maximum DSC color depth a sink supports.
This maximum is cumulative: a sink that reports 12 bpc also supports 10
and 8 bpc.
The previous code used exact "== 10" and "== 12" comparisons chained with
else-if, so a 12 bpc sink only set frl_dsc_12bpc and never set
frl_dsc_10bpc, incorrectly narrowing the DSC bpc range usable with that
sink.
Use ">= 10" and a separate ">= 12" check so a sink advertising a higher
maximum also enables the lower DSC bit depths it supports.

[Why & How]
On resume, dm_resume() walks the connector list and, for each connector,
calls dc_link_detect_connection_type() at the top of the loop iteration
before the per-connector dc_exit_ips_for_hw_access() that sits in the
detection branch. There is no dc_exit_ips_for_hw_access() before the loop,
so the very first HW access relies on an earlier connector having already
taken the display out of IPS.
Commit d1d51519bc3b ("drm/amd/display: Skip eDP detection when no sink")
skips the eDP connector when no panel is present. On a DCN3.5 APU whose
eDP link has no sink, the eDP iteration - which used to bring the HW out
of IPS first - is now skipped, so a downstream DP connector becomes the
first one processed. Its initial DDC/AUX access then runs while the HW is
still idle, the AUX transfers time out (-ETIMEDOUT), and the EDID read
fails:
[drm:dm_helpers_read_local_edid [amdgpu]] *ERROR* EDID err: 2, on connector: DP-1
amdgpu: [drm] *ERROR* No EDID read.
Take the display out of IPS once before the detection loop so the first
connector processed no longer touches the AUX/DDC engine while the HW is
still in idle power state. This keeps the eDP-skip boot/resume
optimization while fixing the DP EDID read failure.

[Why & How]
Currently, init_pipes() is the only interface responsible for
initializing the OPP->MPCC resource for all pipes. However, during
seamless boot transitions, init_pipes() is skipped and we transition
directly to an ODM2:1 config where we end up programming the default SW
struct state of mpc_tree_params, which is 0. This results in a config
where both HUBP0 & HUBP1 are being fed into the same OPP inst, 0 in this
case.
This is purely a case of programming incorrect SW state initialization
values into HW, so fix this by initializing mpc_tree_params with the
correct instances during resource construct.
