Subject[PATCH 1/3] drm/amd/dicplay: move FPU related code from dcn31 to dml/dcn31 folder
Date
Creates FPU files in dml/dcn31 folder to centralize FPU operations
from 3.1x drivers and moves all FPU-associated code from dcn31 driver
to there. It includes the struct _vcs_dpi_ip_params_st and
_vcs_dpi_soc_bounding_box_st and functions:

- dcn31_calculate_wm_and_dlg_fp()
- dcn31_update_bw_bounding_box()

adding dc_assert_fp_enabled to them and drop DC_FP_START/END inside
functions that was moved to dml folder, as required.

+/**
+ * DOC: DCN31x FPU manipulation Overview
+ *
+ * The DCN architecture relies on FPU operations, which require special
+ * compilation flags and the use of kernel_fpu_begin/end functions; ideally, we
+ * want to avoid spreading FPU access across multiple files. 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();
