[Why]
DML has been updated to use per-DPM derates when provided but per-DPM de-rates have not been finalized.
Need to validate to see what values should be stored in the bounding box.
[How]
Add debug options to set custom derates per DPM (starting at DPM0) and their values
Each entry in the custom derate expects the derates to be stored in the following format:
bits 0-7: dram_derate_percent_pixel
bits 8-15: fclk_derate_percent
bits 16-23: dcfclk_derate_percent
bits 24-31 are unused.
e.g. Using the value 0x414020 will set the following derates for DPM0
DPM0: 0x20, 0x40, 0x41 for dram, fclk, and dcfclk respectively
Note that global derate value will be used if the per-DPM derate is 0.

[Why]
The CACP enablement on Linux added panel-type detection and CACP
capability logic that was not covered by KUnit tests.
[How]
Export amdgpu_dm_set_panel_type() and amdgpu_dm_update_cacp_caps() for
KUnit via STATIC_IFN_KUNIT/EXPORT_IF_KUNIT and add unit tests covering:
- amdgpu_dm_update_cacp_caps(): IP version gating (including the 3.1.6
exclusion), eDP/LVDS signal handling, non-eDP signals, and OLED vs LCD
panel types.
- amdgpu_dm_set_panel_type(): VSDB OLED/MINILED, DPCD oled/miniled bits,
the DID path (OLED and LCD), the vendor luminance heuristic, and the
LCD default.
Update the should_create_sysfs backlight tests to reflect the new
OLED/CACP behavior (OLED with/without CACP and LCD eDP panels).

[Why]
In amdgpu_dm_set_panel_type() the DID fallback branch tested and wrote
link->panel_type, while the rest of the function tracked the result in
the local variable panel_type. The final assignment unconditionally
overwrites link->panel_type from panel_type, so the value derived from
DID was always discarded, making the DID branch dead code.
[How]
Use the local panel_type variable in the DID fallback branch so that the
DID result participates in the source priority (VSDB -> DPCD -> DID ->
vendor luminance heuristic -> LCD default) and is preserved by the final
assignment.

stream->sink is optional and can be null, so should always be checked
before dereference. Additionally, most of its usage in DPMS sequences
is for stream->sink->link, which can be replaced with stream->link,
as the two should always be the same.
[How]
* Replace stream->sink->link in DPMS on/off
* Add assert to USB4 BW allocation where sink is required
* Avoid inconsistencies in resource access, e.g. don't repeat
stream->link after it was already saved to a local variable
* Pull out effective VPG calculation to helper getter

[why]
The IGT test kms_plane_alpha_blend@coverage-vs-premult-vs-constant
failed on DCN with ODM 2:1 combine enabled. The test compares the CRC
of a coverage-blended plane against a premultiplied-blended plane and
expects them to be identical. With ODM combine the whole-frame CRC
mismatched (left segment matched, right segment differed).
Root cause: dc_stream_set_dither_option() iterated the pipe_ctx array
and broke out at the first pipe matching the stream (the OTG master /
OPP instance 0), then programmed bit-depth reduction (dither) on that
single OPP only. Under ODM combine there is more than one OPP head, so
the secondary ODM segment (OPP instance 1) was never reprogrammed. When
CRC capture requested dither off, only the left OPP got updated while
the right OPP kept its previous dither setting, producing a different
CRC for the right segment and thus a whole-frame CRC mismatch.
[how]
Use resource_get_otg_master_for_stream() and
resource_get_opp_heads_for_otg_master() to retrieve every OPP head of
the stream, then loop over all of them and call
transform_set_pixel_storage_depth() and opp_program_bit_depth_reduction()
on each. This keeps all OPP heads in sync under ODM combine, so dither is
applied (or cleared) identically across every segment and the CRCs match.

Enabling IPS for D3 allows DMUB to manage idle power savings
when the display subsystem is inactive, reducing platform

[How]
In DCN4 variant resource construct:
- Set dc->caps.ips_support = true
- Remove dc->config.disable_ips = DMUB_IPS_DISABLE_ALL override
This enables DMUB to dynamically manage IPS entry/exit during

nvme_query_fdp_info() allocates the RUH status buffer for at most S8_MAX
- 1 descriptors, and then copies ruhs->ruhsd[] into head->plids[] using
the controller reported ruhs->nruhsd directly as the loop bound.
However, that count wasn't taken into account for the actual buffer's
size, so there was a chance for a controller reporting a larger nruhsd
to cause the copy to overflow the buffer. Clamp nr_plids to the same

The commit fixing the overlayfs mmap() and mprotect() access checks
failed to skip the execmem check in __file_map_prot_check() for the case
where the "mounter check" is being performed. This check should be
performed only against the credentials of the task that is calling
mmap()/mprotect(), since it doesn't pertain to the file itself, but
rather just gates the ability of the calling task to get an executable
memory mapping in general.
The purpose of the "mounter check" is to guard against using an
overlayfs mount to gain file access that would otherwise be denied to
the mounter. For execmem this is not relevant, as there is no further
file access granted based on it (notice that the file's context is not
used as the target in the check), so checking it also against the
mounter credentials would be incorrect.
Fix this by passing a boolean to [__]file_map_prot_check() and
selinux_mmap_file_common() that indicates if we are doing the "mounter
check" and skiping the execmem check in that case. Since this boolean
also indicates if we use current_cred() or the mounter cred as the
subject, also remove the "cred" argument from these functions and
determine it based on the boolean and the file struct.

fwctl_rpc.out_len but never checks it is large enough to hold even the
fwctl_rpc_cxl_out header. With out_len == 0 , kvzalloc() returns
ZERO_SIZE_PTR, which passes the !rpc_out check, the subsequent
rpc_out->size = 0 then writes through the poison pointer.
Reject requests whose output buffer can't hold the response header,
before allocating. The Set Feature reply carries no payload, so the
header is all that is required.

cxlctl_get_feature() sizes its output buffer from the user's
fwctl_rpc.out_len, but the device is told to write
cxl_mbox_get_feat_in.count bytes into rpc_out->payload, which is a
separate user-controlled value. Nothing bounds count against out_len, so
a small out_len with a large count overflows the kvzalloc()'d buffer.
A heap OOB write reachable from FWCTL_RPC.
Reject requests where count exceeds the available payload room, before
allocating.

SCMI transport devices are deliberately excluded from normal SCMI bus
matching so protocol drivers cannot bind to the internal transport
children. However, scmi_device_destroy() uses the same protocol/name
lookup to find devices that must be unregistered during channel teardown.
Split the match helper so driver matching still skips transport devices,
while explicit child lookup can find them for teardown. Use a shared
transport-device name prefix macro for both matching and name generation.
Since transport-device names are derived from direction and protocol ID,
reject duplicate protocol channel setup before creating or finding a
transport device. This prevents malformed firmware with duplicate
protocol child nodes from reusing an existing transport device and then
destroying it when the duplicate IDR insertion fails.

scmi_child_dev_find() drops the reference returned by
device_find_child() before returning the scmi_device pointer. A
concurrent unregister can then release the device while the destroy path
is still using the returned pointer.
Make the lookup helper return the device_find_child() reference and keep
it until scmi_device_destroy() has finished unregistering the child.
Also split device_unregister() in __scmi_device_destroy() so the SCMI bus
ID is not made reusable until after device_del() has removed the old
scmi_dev.N name from sysfs. This avoids a new SCMI device reusing the
same ID while the old device is still registered.
The final device release callback is also a possible cleanup path when
SCMI children are deleted by driver core recursion rather than
__scmi_device_destroy(). Release the SCMI bus ID from a common helper
used by destroy, register-failure and final-release paths, and clear
scmi_dev->id after freeing it so the final release cannot free the same
ID again.

mailbox_chan_setup() can request an additional P2A receiver channel after
successfully acquiring the primary P2A channel. If that later request
fails, the function returns immediately and leaves the primary channel
allocated.
Unwind the primary mailbox channel before returning the error so probe
deferral or other setup failures do not leave the channel busy for later
probe attempts.
