With this idea in * mind, this file aims to centralize all DCN3.1.x 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(); */ struct _vcs_dpi_ip_params_st dcn3_1_ip = { .gpuvm_enable = 1, .gpuvm_max_page_table_levels = 1, .hostvm_enable = 1, .hostvm_max_page_table_levels = 2, .rob_buffer_size_kbytes = 64, .det_buffer_size_kbytes = DCN3_1_DEFAULT_DET_SIZE, .config_return_buffer_size_in_kbytes = 1792, .compressed_buffer_segment_size_in_kbytes = 64, .meta_fifo_size_in_kentries = 32, .zero_size_buffer_entries = 512, .compbuf_reserved_space_64b = 256, .compbuf_reserved_space_zs = 64, .dpp_output_buffer_pixels = 2560, .opp_output_buffer_lines = 1, .pixel_chunk_size_kbytes = 8, .meta_chunk_size_kbytes = 2, .min_meta_chunk_size_bytes = 256, .writeback_chunk_size_kbytes = 8, .ptoi_supported = false, .num_dsc = 3, .maximum_dsc_bits_per_component = 10, .dsc422_native_support = false, .is_line_buffer_bpp_fixed = true, .line_buffer_fixed_bpp = 48, .line_buffer_size_bits = 789504, .max_line_buffer_lines = 12, .writeback_interface_buffer_size_kbytes = 90, .max_num_dpp = 4, .max_num_otg = 4, .max_num_hdmi_frl_outputs = 1, .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 = 6, .max_vscl_ratio = 6, .max_hscl_taps = 8, .max_vscl_taps = 8, .dpte_buffer_size_in_pte_reqs_luma = 64, .dpte_buffer_size_in_pte_reqs_chroma = 34, .dispclk_ramp_margin_percent = 1, .max_inter_dcn_tile_repeaters = 8, .cursor_buffer_size = 16, .cursor_chunk_size = 2, .writeback_line_buffer_buffer_size = 0, .writeback_min_hscl_ratio = 1, .writeback_min_vscl_ratio = 1, .writeback_max_hscl_ratio = 1, .writeback_max_vscl_ratio = 1, .writeback_max_hscl_taps = 1, .writeback_max_vscl_taps = 1, .dppclk_delay_subtotal = 46, .dppclk_delay_scl = 50, .dppclk_delay_scl_lb_only = 16, .dppclk_delay_cnvc_formatter = 27, .dppclk_delay_cnvc_cursor = 6, .dispclk_delay_subtotal = 119, .dynamic_metadata_vm_enabled = false, .odm_combine_4to1_supported = false, .dcc_supported = true, };
