/**
 * 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();
