With this idea in * mind, this file aims to centralize all DCN20 and DCN2.1 (DCN2x) functions * that require FPU access in a single place. Code in this file follows the * following code pattern: * * 1. Functions that use FPU operations should be isolated in static functions. * 2. The FPU functions should have the noinline attribute to ensure anything * that deals with FP register is contained within this call. * 3. All function that needs to be accessed outside this file requires a * public interface that not uses any FPU reference. * 4. Developers **must not** use DC_FP_START/END in this file, but they need * to ensure that the caller invokes it before access any function available * in this file. For this reason, public functions in this file must invoke * dc_assert_fp_enabled(); * * Let's expand a little bit more the idea in the code pattern. To fully * isolate FPU operations in a single place, we must avoid situations where * compilers spill FP values to registers due to FP enable in a specific C * file. Note that even if we isolate all FPU functions in a single file and * call its interface from other files, the compiler might enable the use of * FPU before we call DC_FP_START. Nevertheless, it is the programmer's * responsibility to invoke DC_FP_START/END in the correct place. To highlight * situations where developers forgot to use the FP protection before calling * the DC FPU interface functions, we introduce a helper that checks if the * function is invoked under FP protection. If not, it will trigger a kernel * warning. */ struct _vcs_dpi_ip_params_st dcn2_0_ip = { .odm_capable = 1, .gpuvm_enable = 0, .hostvm_enable = 0, .gpuvm_max_page_table_levels = 4, .hostvm_max_page_table_levels = 4, .hostvm_cached_page_table_levels = 0, .pte_group_size_bytes = 2048, .num_dsc = 6, .rob_buffer_size_kbytes = 168, .det_buffer_size_kbytes = 164, .dpte_buffer_size_in_pte_reqs_luma = 84, .pde_proc_buffer_size_64k_reqs = 48, .dpp_output_buffer_pixels = 2560, .opp_output_buffer_lines = 1, .pixel_chunk_size_kbytes = 8, .pte_chunk_size_kbytes = 2, .meta_chunk_size_kbytes = 2, .writeback_chunk_size_kbytes = 2, .line_buffer_size_bits = 789504, .is_line_buffer_bpp_fixed = 0, .line_buffer_fixed_bpp = 0, .dcc_supported = true, .max_line_buffer_lines = 12, .writeback_luma_buffer_size_kbytes = 12, .writeback_chroma_buffer_size_kbytes = 8, .writeback_chroma_line_buffer_width_pixels = 4, .writeback_max_hscl_ratio = 1, .writeback_max_vscl_ratio = 1, .writeback_min_hscl_ratio = 1, .writeback_min_vscl_ratio = 1, .writeback_max_hscl_taps = 12, .writeback_max_vscl_taps = 12, .writeback_line_buffer_luma_buffer_size = 0, .writeback_line_buffer_chroma_buffer_size = 14643, .cursor_buffer_size = 8, .cursor_chunk_size = 2, .max_num_otg = 6, .max_num_dpp = 6, .max_num_wb = 1, .max_dchub_pscl_bw_pix_per_clk = 4, .max_pscl_lb_bw_pix_per_clk = 2, .max_lb_vscl_bw_pix_per_clk = 4, .max_vscl_hscl_bw_pix_per_clk = 4, .max_hscl_ratio = 8, .max_vscl_ratio = 8, .hscl_mults = 4, .vscl_mults = 4, .max_hscl_taps = 8, .max_vscl_taps = 8, .dispclk_ramp_margin_percent = 1, .underscan_factor = 1.10, .min_vblank_lines = 32, // .dppclk_delay_subtotal = 77, // .dppclk_delay_scl_lb_only = 16, .dppclk_delay_scl = 50, .dppclk_delay_cnvc_formatter = 8, .dppclk_delay_cnvc_cursor = 6, .dispclk_delay_subtotal = 87, // .dcfclk_cstate_latency = 10, // SRExitTime .max_inter_dcn_tile_repeaters = 8, .xfc_supported = true, .xfc_fill_bw_overhead_percent = 10.0, .xfc_fill_constant_bytes = 0, .number_of_cursors = 1, };
