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	*
