<id>073875c5d27c89e7fe831e9496f8f9c2fd9e95ea</id>
<content type='text'>
[Why]
Dynamic expansion is not needed when outputting 12bpc test patterns.

[How]
Add a debug flag to control disabling dynamic expansion in the case
of 12bpc test patterns.

[Why]
Resolve compiler warnings by marking unused parameters explicitly.

[How]
In .c and .h function definitions, keep parameter names
in signatures and add a line with `(void)param;` in function body

Preserved function signatures and avoids breaking code paths that
may reference the parameter under conditional compilation.

<title>drm/amd/display: Add more DC HW state info to underflow logging</title>
<updated>2025-10-28T13:57:44+00:00</updated>

<id>dbf58a9dad4d80286c5c17e199f595eb0dd3be5a</id>
<content type='text'>
[Why]
Debugging underflow issues frequently requires knowing the
HW state at the time of underflow. To enable capturing this
HW state information, interface functions are needed for the
various DC HW blocks.

[How]
This change adds the interface functions to read HW state for
the following DC HW blocks:
- HUBBUB
- HUBP
- DPP
- MPC
- OPP
- DSC
- OPTC
- DCCG
