[why] The DP KVM failed to light up, since the lttpr_mode is not reset to default value when failed to read LTTPR capabilities, and the variable max_link_rate retains a initial value zero, this cause variable link_rate be assigned to an error value zero, consquently pixel_clock get wrong value zero, and kvm can't light up. [how] Reset lttpr_mode to default value when failed to read LTTPR capabilities, so that the link_rate fallbacks to the minimum rate that supported by link encoder and sink. Reviewed-by:

FPU operations in dcn10 was already moved to dml folder via calcs code. However, dcn1_0_ip and dcn_1_0_soc with FPU componentd remains on dcn10. Following previous changes to isolate FPU, this patch creates dcn10_fpu files to isolate FPU-specific code and moves those structs to it. Signed-off-by:

dml/dcn20_fpu file centralizes all DCN2x functions that require FPU access. Therefore, this patch moves FPU-related code from dcn21 to dcn20_fpu. These include: - dcn21_populate_dml_pipes_from_context() - dcn21_validate_bandwidth_fp() and related: - dcn21_calculate_wm(), - patch_bounding_box(), - calculate_wm_set_for_vlevel() - renaming update_bw_bounding_box() to dcn21_update_bw_bounding_box(), move to dcn20_fpu with related static function construct_low_pstate_lvl() Also, make dcn21_fast_validate_bw() public in dcn21_resource as it is called by dcn21_validate_bandwidth_fp() now in dcn20_fpu. Reuse dcn20_fpu_adjust_dppclk() in dcn21_fast_validate_bw() as it isolates the same FPU operation. Include dchubbub.h as it is required in dcn21_populate_dml_pipes_from_context() Signed-off-by:

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.

[Why] On LNX, TO_CLK_MGR_INTERNAL() only works to get clk_mgr_internal from a given clk_mgr. In clk_mgr_dcn316 struct, the clk_mgr_internal is already a memeber by the alias 'base' [How] Use &clk_mgr->base instead. Reviewed-by:

[Why] The issue only occurs during the GPU reset code path. We first backup the current state prior to commiting 0 streams internally from DM to DC. This state backup contains valid link encoder assignments. DC will clear the link encoder assignments as part of current state (but not the backup, since it was a copied before the commit) and free the extra stream reference it held. DC requires that the link encoder assignments remain cleared/invalid prior to commiting. Since the backup still has valid assignments we call the interface post reset to clear them. This routine also releases the extra reference that the link encoder interface held - resulting in a double free (and eventually a NULL pointer dereference). [How] We'll have to do a full DC commit anyway after GPU reset because the stream count previously went to 0. We don't need to retain the assignment that we had backed up, so just copy off of the now clean current state assignment after the reset has occcurred with the new link_enc_cfg_copy() interface.
