36  * DOC: DCN31x FPU manipulation Overview
37  *
38  * The DCN architecture relies on FPU operations, which require special
39  * compilation flags and the use of kernel_fpu_begin/end functions; ideally, we
40  * want to avoid spreading FPU access across multiple files. With this idea in
41  * mind, this file aims to centralize all DCN3.1.x functions that require FPU
42  * access in a single place. Code in this file follows the following code
43  * pattern:
44  *
45  * 1. Functions that use FPU operations should be isolated in static functions.
46  * 2. The FPU functions should have the noinline attribute to ensure anything
47  *    that deals with FP register is contained within this call.
48  * 3. All function that needs to be accessed outside this file requires a
49  *    public interface that not uses any FPU reference.
50  * 4. Developers **must not** use DC_FP_START/END in this file, but they need
51  *    to ensure that the caller invokes it before access any function available
52  *    in this file. For this reason, public functions in this file must invoke
53  *    dc_assert_fp_enabled();
