52  * DOC: DCN2x FPU manipulation Overview
53  *
54  * The DCN architecture relies on FPU operations, which require special
55  * compilation flags and the use of kernel_fpu_begin/end functions; ideally, we
56  * want to avoid spreading FPU access across multiple files. With this idea in
57  * mind, this file aims to centralize all DCN20 and DCN2.1 (DCN2x) functions
58  * that require FPU access in a single place. Code in this file follows the
59  * following code pattern:
60  *
61  * 1. Functions that use FPU operations should be isolated in static functions.
62  * 2. The FPU functions should have the noinline attribute to ensure anything
63  *    that deals with FP register is contained within this call.
64  * 3. All function that needs to be accessed outside this file requires a
65  *    public interface that not uses any FPU reference.
66  * 4. Developers **must not** use DC_FP_START/END in this file, but they need
67  *    to ensure that the caller invokes it before access any function available
68  *    in this file. For this reason, public functions in this file must invoke
69  *    dc_assert_fp_enabled();
70  *
71  * Let's expand a little bit more the idea in the code pattern. To fully
72  * isolate FPU operations in a single place, we must avoid situations where
73  * compilers spill FP values to registers due to FP enable in a specific C
74  * file. Note that even if we isolate all FPU functions in a single file and
75  * call its interface from other files, the compiler might enable the use of
76  * FPU before we call DC_FP_START. Nevertheless, it is the programmer's
77  * responsibility to invoke DC_FP_START/END in the correct place. To highlight
78  * situations where developers forgot to use the FP protection before calling
79  * the DC FPU interface functions, we introduce a helper that checks if the
80  * function is invoked under FP protection. If not, it will trigger a kernel
81  * warning.
