2026-05-18Revert "drm/amd/display: dmub_cmd.h: add missing kernel-doc for enums"James Lin1-108/+48
[Why & How] This reverts commit f71d0b68ec58b781f4f44ea642846bedce075e85. 1. Auto-generated Header: The file 'dmub_cmd.h' is an auto-generated header managed in an external repository (dmu_stg). Manual changes made directly in this repository will be overwritten and lost during the next automated weekly synchronization. 2. Tooling Compatibility: This header is governed by internal AMD firmware standards which require Doxygen formatting for cross-team documentation. Moving to kernel-doc syntax may break internal documentation pipelines. 3. Suppressing Warnings: Current 'make htmldocs' and 'make W=1' builds do not actively scan 'dmub_cmd.h' for kernel-doc compliance, thus no warnings are triggered during standard compilation. To address warnings generated when manually running './scripts/kernel-doc', we have added a notice at the file header indicating that this is an auto-generated file that does not strictly follow kernel-doc formatting. This ensures that any future linting tools or manual checks recognize the formatting as intentional.

2026-05-05drm/amd/display: Fix type mismatches in DC and DMUB modulesGaghik Khachatrian2-2/+2
[Why] Address signed/unsigned comparison warnings across dc paths to keep builds warning-clean and improve type safety at comparison boundaries. Most warnings came from signed loop/index temporaries compared against unsigned counters and table sizes, plus a smaller number of mixed signed/unsigned clock, bandwidth, and geometry comparisons. [How] Aligned loop/index and bound types in the affected modules and DMUB sources, including color, freesync, power, stats, and vmid paths. Used unsigned iterators where bounds/counters are unsigned, preserved signed types where negative values are meaningful, and updated related format specifiers where type changes required it. Changes are limited to warning resolution and type alignment. No functional behavior change is intended.

2026-05-05drm/amd/display: dmub_cmd.h: add missing kernel-doc for enumsRandy Dunlap1-48/+108
For enums that have a kernel-doc ("/**") comment block, add or correct their kernel-doc to eliminate all kernel-doc enum warnings. Some of these needed "struct" changed to "enum" in the kernel-doc header. For a few of them, I changed the "/**" comment to a plain "/*" comment since there was no kernel-doc content there. Example: Warning: drivers/gpu/drm/amd/display/dmub/inc/dmub_cmd.h:2673 Enum value 'FAMS2_ALLOW_DELAY_CHECK_NONE' not described in enum 'dmub_fams2_allow_delay_check_mode' Warning: drivers/gpu/drm/amd/display/dmub/inc/dmub_cmd.h:2673 Enum value 'FAMS2_ALLOW_DELAY_CHECK_FROM_START' not described in enum 'dmub_fams2_allow_delay_check_mode' Warning: drivers/gpu/drm/amd/display/dmub/inc/dmub_cmd.h:2673 Enum value 'FAMS2_ALLOW_DELAY_CHECK_FROM_PREPARE' not described in enum 'dmub_fams2_allow_delay_check_mode' All .o files are the same with or without this patch.
