It is + * also responsible for lazy FPU handling and some of the context loading + * in raw mode. + * + * There are three CPU contexts, the most important one is the guest one (GC). + * When running in raw-mode (RC) there is a special hyper context for the VMM + * part that floats around inside the guest address space. When running in + * raw-mode, CPUM also maintains a host context for saving and restoring + * registers across world switches. This latter is done in cooperation with the + * world switcher (@see pg_vmm). + * + * @see grp_cpum + * + * @section sec_cpum_fpu FPU / SSE / AVX / ++ state. + * + * TODO: proper write up, currently just some notes. + * + * The ring-0 FPU handling per OS: + * + * - 64-bit Windows uses XMM registers in the kernel as part of the calling + * convention (Visual C++ doesn't seem to have a way to disable + * generating such code either), so CR0.TS/EM are always zero from what I + * can tell. We are also forced to always load/save the guest XMM0-XMM15 + * registers when entering/leaving guest context. Interrupt handlers + * using FPU/SSE will offically have call save and restore functions + * exported by the kernel, if the really really have to use the state. + * + * - 32-bit windows does lazy FPU handling, I think, probably including + * lazying saving. The Windows Internals book states that it's a bad + * idea to use the FPU in kernel space. However, it looks like it will + * restore the FPU state of the current thread in case of a kernel \#NM. + * Interrupt handlers should be same as for 64-bit. + * + * - Darwin allows taking \#NM in kernel space, restoring current thread's + * state if I read the code correctly. It saves the FPU state of the + * outgoing thread, and uses CR0.TS to lazily load the state of the + * incoming one. No idea yet how the FPU is treated by interrupt + * handlers, i.e. whether they are allowed to disable the state or + * something. + * + * - Linux also allows \#NM in kernel space (don't know since when), and + * uses CR0.TS for lazy loading. Saves outgoing thread's state, lazy + * loads the incoming unless configured to agressivly load it. Interrupt + * handlers can ask whether they're allowed to use the FPU, and may + * freely trash the state if Linux thinks it has saved the thread's state + * already. This is a problem. + * + * - Solaris will, from what I can tell, panic if it gets an \#NM in kernel + * context. When switching threads, the kernel will save the state of + * the outgoing thread and lazy load the incoming one using CR0.TS. + * There are a few routines in seeblk.s which uses the SSE unit in ring-0 + * to do stuff, HAT are among the users. The routines there will + * manually clear CR0.TS and save the XMM registers they use only if + * CR0.TS was zero upon entry. They will skip it when not, because as + * mentioned above, the FPU state is saved when switching away from a + * thread and CR0.TS set to 1, so when CR0.TS is 1 there is nothing to + * preserve. This is a problem if we restore CR0.TS to 1 after loading + * the guest state. + * + * - FreeBSD - no idea yet. + * + * - OS/2 does not allow \#NMs in kernel space IIRC. Does lazy loading, + * possibly also lazy saving. Interrupts must preserve the CR0.TS+EM & + * FPU states. + * + * Up to r107425 (2016-05-24) we would only temporarily modify CR0.TS/EM while + * saving and restoring the host and guest states. The motivation for this + * change is that we want to be able to emulate SSE instruction in ring-0 (IEM). + * + * Starting with that change, we will leave CR0.TS=EM=0 after saving the host + * state and only restore it once we've restore the host FPU state. This has the + * accidental side effect of triggering Solaris to preserve XMM registers in + * sseblk.s. When CR0 was changed by saving the FPU state, CPUM must now inform + * the VT-x (HMVMX) code about it as it caches the CR0 value in the VMCS. + * + * + * @section sec_cpum_logging Logging Level Assignments. + * + * Following log level assignments: + * - Log6 is used for FPU state management. + * - Log7 is used for FPU state actualization. + * + */ + +
