Modified Files: src/sys/arch/x86/include: cpu.h src/sys/arch/x86/x86: x86_machdep.c Log Message: x86: Export fpu_save, fpu_save_size, xsave_features to dedicated sysctl nodes Add new defines: - CPU_FPU_SAVE (15) int: FPU Instructions layout * to use this, CPU_OSFXSR must be true * 0: FSAVE * 1: FXSAVE * 2: XSAVE * 3: XSAVEOPT - CPU_FPU_SAVE_SIZE (16) int: FPU Instruction layout size - CPU_XSAVE_FEATURES (17) quad: FPU XSAVE features Bump CPU_MAXID from 15 to 18. These values were prepared originally to be exported without ASCIIZ name to be used as handler. These values are useful to get FPU accessors in a debugger easier to implement on x86 (PT_SETFPREG, PT_GETFPREG). This interface handles all supported x86 targets. In the older (i386) and less featured CPUs check first osfxsr (OS uses FXSAVE/FXRSTOR). According to sys/arch/x86/include/cpu.h r.1.65 this was prepared to be exported beyond simple CTL_CREATE node.
