VMM/CPUM: Advertise SSE3, SSE4.1, SSE4.2 and LAHF/SAHF instruction set extensions on arm64 to bring us to x86-64 micro architecture level 2 (x86-64-v2) in order to run more recent Linux guests (like OL 9.2) which raised the bar, bugref:9898

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 *
