*: Mark functions as static if not used outside of a given compilation unit. Enables the compiler to optimize inlining, reduces the symbol tables, exposes unused functions and in some rare cases exposes mismtaches between function declarations and definitions, but most importantly reduces the number of parfait reports for the extern-function-no-forward-declaration category. This should not result in any functional changes, bugref:3409

29 *
30 * The CPU Monitor / Manager keeps track of all the CPU registers. It is
31 * also responsible for lazy FPU handling and some of the context loading
32 * in raw mode.
33 *
34 * There are three CPU contexts, the most important one is the guest one (GC).
35 * When running in raw-mode (RC) there is a special hyper context for the VMM
36 * part that floats around inside the guest address space. When running in
37 * raw-mode, CPUM also maintains a host context for saving and restoring
38 * registers across world switches. This latter is done in cooperation with the
39 * world switcher (@see pg_vmm).
40 *
41 * @see grp_cpum
42 *
43 * @section sec_cpum_fpu FPU / SSE / AVX / ++ state.
44 *
45 * TODO: proper write up, currently just some notes.
46 *
47 * The ring-0 FPU handling per OS:
48 *
49 * - 64-bit Windows uses XMM registers in the kernel as part of the calling
50 * convention (Visual C++ doesn't seem to have a way to disable
51 * generating such code either), so CR0.TS/EM are always zero from what I
52 * can tell. We are also forced to always load/save the guest XMM0-XMM15
53 * registers when entering/leaving guest context. Interrupt handlers
54 * using FPU/SSE will offically have call save and restore functions
55 * exported by the kernel, if the really really have to use the state.
56 *
57 * - 32-bit windows does lazy FPU handling, I think, probably including
58 * lazying saving. The Windows Internals book states that it's a bad
59 * idea to use the FPU in kernel space. However, it looks like it will
60 * restore the FPU state of the current thread in case of a kernel \#NM.
61 * Interrupt handlers should be same as for 64-bit.
62 *
63 * - Darwin allows taking \#NM in kernel space, restoring current thread's
64 * state if I read the code correctly. It saves the FPU state of the
65 * outgoing thread, and uses CR0.TS to lazily load the state of the
66 * incoming one. No idea yet how the FPU is treated by interrupt
67 * handlers, i.e. whether they are allowed to disable the state or
68 * something.
69 *
70 * - Linux also allows \#NM in kernel space (don't know since when), and
71 * uses CR0.TS for lazy loading. Saves outgoing thread's state, lazy
72 * loads the incoming unless configured to agressivly load it. Interrupt
73 * handlers can ask whether they're allowed to use the FPU, and may
74 * freely trash the state if Linux thinks it has saved the thread's state
75 * already. This is a problem.
76 *
77 * - Solaris will, from what I can tell, panic if it gets an \#NM in kernel
78 * context. When switching threads, the kernel will save the state of
79 * the outgoing thread and lazy load the incoming one using CR0.TS.
80 * There are a few routines in seeblk.s which uses the SSE unit in ring-0
81 * to do stuff, HAT are among the users. The routines there will
82 * manually clear CR0.TS and save the XMM registers they use only if
83 * CR0.TS was zero upon entry. They will skip it when not, because as
84 * mentioned above, the FPU state is saved when switching away from a
85 * thread and CR0.TS set to 1, so when CR0.TS is 1 there is nothing to
86 * preserve. This is a problem if we restore CR0.TS to 1 after loading
87 * the guest state.
88 *
89 * - FreeBSD - no idea yet.
90 *
91 * - OS/2 does not allow \#NMs in kernel space IIRC. Does lazy loading,
92 * possibly also lazy saving. Interrupts must preserve the CR0.TS+EM &
93 * FPU states.
94 *
95 * Up to r107425 (2016-05-24) we would only temporarily modify CR0.TS/EM while
96 * saving and restoring the host and guest states. The motivation for this
97 * change is that we want to be able to emulate SSE instruction in ring-0 (IEM).
98 *
99 * Starting with that change, we will leave CR0.TS=EM=0 after saving the host
100 * state and only restore it once we've restore the host FPU state. This has the
101 * accidental side effect of triggering Solaris to preserve XMM registers in
102 * sseblk.s. When CR0 was changed by saving the FPU state, CPUM must now inform
103 * the VT-x (HMVMX) code about it as it caches the CR0 value in the VMCS.
104 *
105 *
106 * @section sec_cpum_logging Logging Level Assignments.
107 *
108 * Following log level assignments:
109 * - Log6 is used for FPU state management.
110 * - Log7 is used for FPU state actualization.
111 *
