drm/amd/display: Fix Compiler warnings in dmub

2026-03-30T19:12:41Z

[Why] Resolve compiler warnings by marking unused parameters explicitly. [How] In .c and .h files, keep parameter names in signatures and add a line with`(void)param;` inside the function body Preserved function signatures and avoids breaking code paths that may reference the parameter under conditional compilation.

drm/amd/display: Fix Silence Conversion Warnings in Dmub

2026-03-30T18:54:47Z

Fix Conversion that might result in a loss of data warnings in dmub/src/: - dmub_dcn20/31/32/35/42/60/401.c: Add ASSERT(value <= 0xFF) and explicit (uint8_t) cast when storing REG_GET results into uint8_t debug struct fields. Add != 0 for bool assignments from uint32_t bitfield reads. - dmub_reg.c: Cast va_arg shift value to uint8_t with ASSERT guard before passing to set_reg_field_value_masks(). - dmub_srv.c: Widen num_pending to uint64_t to match uint64_t arithmetic; use != 0 for bool assignments from unsigned expressions. No functional change intended. Reviewed-by: Dillon Varone Signed-off-by: Gaghik Khachatrian Signed-off-by: Chuanyu Tseng Signed-off-by: Alex Deucher

2026-03-23T18:16:03Z

1. Add LIVE_CAPTURE_WITH_CVT bit (bit[2]) in union replay_optimization to control this feature via DalRegKey_ReplayOptimization. 2. Check the bit in mod_power_set_live_capture_with_cvt_activate function before enabling live capture with CVT. 3. Use LIVE_CAPTURE_WITH_CVT to control if Replay want to send CVT in live + capture or not. Reviewed-by: Leon Huang Signed-off-by: ChunTao Tso Signed-off-by: Chuanyu Tseng Signed-off-by: Alex Deucher
