drm/amd/display: protect remaining FPU-code calls on dcn3.1.x

2022-04-28T21:44:02Z

From [1], I realized two other calls to dcn30 code are associated with FPU operations and are not protected by DC_FP_* macros: * dcn30_populate_dml_writeback_from_context() * dcn30_set_mcif_arb_params() So, since FPU-associated code is not fully isolated in dcn30, and dcn3.1.x reuses them, let's wrap their calls properly. Note: this patch complements the fix from [1].

drm/amd/display: move FPU-related code from dcn20 to dml folder

2022-03-15T18:25:16Z

Move parts of dcn20 code that uses FPU to dml folder. It aims to isolate FPU operations as described by series: drm/amd/display: Introduce FPU directory inside DC https://patchwork.freedesktop.org/series/93042/ This patch moves the following functions from dcn20_resource to dml/dcn20_fpu and calls of public functions in dcn20_resource are wrapped by DC_FP_START/END(): - void dcn20_populate_dml_writeback_from_context - static bool is_dtbclk_required() - static enum dcn_zstate_support_state() - void dcn20_calculate_dlg_params() - static void swizzle_to_dml_params() - int dcn20_populate_dml_pipes_from_context() - void dcn20_calculate_wm() - void dcn20_cap_soc_clocks() - void dcn20_update_bounding_box() - void dcn20_patch_bounding_box() - bool dcn20_validate_bandwidth_fp() This movement also affects dcn21/30/31, as dcn20_calculate_dlg_params() is used by them. For this reason, I included dcn20_fpu headers in dcn20_resource headers to make dcn20_calculate_dlg_params() visible to dcn21/30/31. Three new functions are created to isolate well-delimited FPU operations: - void dcn20_fpu_set_wb_arb_params(): set cli_watermark, pstate_watermark and time_per_pixel from wb_arb_params (struct mcif_arb_params), since those uses FPU operations on double types: WritebackUrgentWatermark, WritebackDRAMClockChangeWatermark, '16.0'. - void dcn20_fpu_set_wm_ranges(): set min_fill_clk_mhz and max_fill_clk_mhz involves FPU calcs on dram_speed_mts (double type); - void dcn20_fpu_adjust_dppclk(): adjust operation on RequiredDPPCLK that is a double.
