| /** |
| * 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(); |
