19 *
20 * The CPU Monitor / Manager keeps track of all the CPU registers. It is
21 * also responsible for lazy FPU handling and some of the context loading
22 * in raw mode.
23 *
24 * There are three CPU contexts, the most important one is the guest one (GC).
25 * When running in raw-mode (RC) there is a special hyper context for the VMM
26 * part that floats around inside the guest address space. When running in
27 * raw-mode, CPUM also maintains a host context for saving and restoring
28 * registers across world switches. This latter is done in cooperation with the
29 * world switcher (@see pg_vmm).
30 *
31 * @see grp_cpum
32 *
33 * @section sec_cpum_fpu FPU / SSE / AVX / ++ state.
34 *
35 * TODO: proper write up, currently just some notes.
36 *
37 * The ring-0 FPU handling per OS:
38 *
39 * - 64-bit Windows uses XMM registers in the kernel as part of the calling
40 * convention (Visual C++ doesn't seem to have a way to disable
41 * generating such code either), so CR0.TS/EM are always zero from what I
42 * can tell. We are also forced to always load/save the guest XMM0-XMM15
43 * registers when entering/leaving guest context. Interrupt handlers
44 * using FPU/SSE will offically have call save and restore functions
45 * exported by the kernel, if the really really have to use the state.
46 *
47 * - 32-bit windows does lazy FPU handling, I think, probably including
48 * lazying saving. The Windows Internals book states that it's a bad
49 * idea to use the FPU in kernel space. However, it looks like it will
50 * restore the FPU state of the current thread in case of a kernel \#NM.
51 * Interrupt handlers should be same as for 64-bit.
52 *
53 * - Darwin allows taking \#NM in kernel space, restoring current thread's
54 * state if I read the code correctly. It saves the FPU state of the
55 * outgoing thread, and uses CR0.TS to lazily load the state of the
56 * incoming one. No idea yet how the FPU is treated by interrupt
57 * handlers, i.e. whether they are allowed to disable the state or
58 * something.
59 *
60 * - Linux also allows \#NM in kernel space (don't know since when), and
61 * uses CR0.TS for lazy loading. Saves outgoing thread's state, lazy
62 * loads the incoming unless configured to agressivly load it. Interrupt
63 * handlers can ask whether they're allowed to use the FPU, and may
64 * freely trash the state if Linux thinks it has saved the thread's state
65 * already. This is a problem.
66 *
67 * - Solaris will, from what I can tell, panic if it gets an \#NM in kernel
68 * context. When switching threads, the kernel will save the state of
69 * the outgoing thread and lazy load the incoming one using CR0.TS.
70 * There are a few routines in seeblk.s which uses the SSE unit in ring-0
71 * to do stuff, HAT are among the users. The routines there will
72 * manually clear CR0.TS and save the XMM registers they use only if
73 * CR0.TS was zero upon entry. They will skip it when not, because as
74 * mentioned above, the FPU state is saved when switching away from a
75 * thread and CR0.TS set to 1, so when CR0.TS is 1 there is nothing to
76 * preserve. This is a problem if we restore CR0.TS to 1 after loading
77 * the guest state.
78 *
79 * - FreeBSD - no idea yet.
80 *
81 * - OS/2 does not allow \#NMs in kernel space IIRC. Does lazy loading,
82 * possibly also lazy saving. Interrupts must preserve the CR0.TS+EM &
83 * FPU states.
84 *
85 * Up to r107425 (2016-05-24) we would only temporarily modify CR0.TS/EM while
86 * saving and restoring the host and guest states. The motivation for this
87 * change is that we want to be able to emulate SSE instruction in ring-0 (IEM).
88 *
89 * Starting with that change, we will leave CR0.TS=EM=0 after saving the host
90 * state and only restore it once we've restore the host FPU state. This has the
91 * accidental side effect of triggering Solaris to preserve XMM registers in
92 * sseblk.s. When CR0 was changed by saving the FPU state, CPUM must now inform
93 * the VT-x (HMVMX) code about it as it caches the CR0 value in the VMCS.
94 *
95 *
96 * @section sec_cpum_logging Logging Level Assignments.
97 *
98 * Following log level assignments:
99 * - Log6 is used for FPU state management.
100 * - Log7 is used for FPU state actualization.
