drm/amd/display: Account for cursor prefetch BW in DML1 mode support

2024-07-01T20:10:35Z

[Description] We need to ensure to take into account cursor prefetch BW in mode support or we may pass ModeQuery but fail an actual flip which will cause a hang. Flip may fail because the cursor_pre_bw is populated during mode programming (and mode programming is never called prior to ModeQuery).

drm/amd/display: Fix possible overflow in integer multiplication

2024-07-01T20:06:53Z

[WHAT & HOW] Integer multiplies integer may overflow in context that expects an expression of unsigned/siged long long (64 bits). This can be fixed by casting integer to unsigned/siged long long to force 64 bits results. This fixes 26 OVERFLOW_BEFORE_WIDEN issues reported by Coverity.

drm/amd/display: Add null checks before accessing struct elements

2024-06-27T21:10:37Z

[WHAT] 1. is_pwrseq0 needs to check link before accessing link->link_index. 2. context is checked before accessing its bw_ctx.dml2 3. clk_mgr_base->bw_params is checked before clk_table.num_entries_per_cl This fixes 4 REVERSE_INULL issues reported by Coverity.

drm/amd/display: Remove redundant var from display_rq_dig_calc in dml

2024-06-27T21:10:35Z

[WHY] Coverity analysis flagged these files as containing DEADCODE, i. e. redundant or unreachabale. In these files, variable 'mode_422' is always the same file (0 or false), so any code logic with it is redundant. [HOW] Removed 'mode_422' variable and all code with it from 'display_rq_dlg_calc_' functions in dml.

drm/amd/display: Covert integers to double before divisions

2024-06-19T16:44:55Z

Integer divisions result in loss of fractional and accuracy is lost when assigned or compared with double. It is necessary to perform double/integer instead or explicitly cast them to double.
