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. * */
