|
---|
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.
