Modified Files: src/sys/arch/x86/include: fpu.h src/sys/arch/x86/x86: fpu.c src/sys/dev/nvmm/x86: nvmm_x86_svm.c Log Message: Improvements in NVMM * Handle the FPU differently, limit the states via the given mask rather than via XCR0. Align to 64 bytes. Provide an initial gXCR0, to be sure that XCR0_X87 is set. Reset XSTATE_BV when the state is modified by the virtualizer, to force a reload from memory. * Hide RDTSCP. * Zero-extend RBX/RCX/RDX when handling the NVMM CPUID signature. * Take ECX and not RCX on MSR instructions.
