Removed iemFRegIsFxSaveFormat.

VMM,REM: Allocate the FPU/SSE/AVX/FUTURE state stuff. We need to use pointers to substates anyway and this will make CPUMCPU much smaller.

CPUMCTX,CPUMHOST: Replaced the fpu (X86FXSAVE) member with an XState (X86XSAVEAREA) member.

Corrected x86.h/mac typo.

VMM,REM: CPUID revamp - almost there now.

IEM: Improved ENTER implementation (thanks Intel!).

VMM/MSRs: Added status codes for returning to ring-3 to service the MSR access.

IEM/IRET: Make the 16-bit IRET real/v86 mode instruction clear RF, doesn't make sense not to do it...

IEM: Call gate TSS access needs to check TSS bitness, not gate, duh.

Committed more than I had intended...

VMM/IEM: nit.

VMM/IEM: Implemented hardware task-switches, code path disabled.

VMM/IEMAllCImpl: Comment clarification about reserved bits in CR4 for raising GP.

IEM: Fixed several instances of iEffSeg being accessed before the decoding was over, causing iPXE to guru on us. Implemented DAS and DAA to verify the previous fix.

VMM: Warnings.

Log the 10 first wrmsr GPs.

Solaris reads MSR_RAPL_POWER_UNIT, give it some fake values.

IEM: Adjust iret CS for ring compression in raw-mode.

I/O breakpoints for raw-mode and non-string instructions in IEM.

IEM: syscall and sysret.

IEM: SS=0 fixes, the right way this time.

CPUM,++: Fix DR6 and DR7 read-as-1 (RA1) and read-as-zero (RAZ) values on load since REM didn't set them right for years. Introduced constants for these values.

IEM: Implemented swapgs

IEM: Implemented the mwait & monitor instructions. (Still work to be done on mwait in EM, but that's a different topic.)

IEM: More 64-bit fixes.

IEM: lldr 0

IEM: More 64-bit fixes.

Fix: mov ss, ax; where ax is 0 in long mode.

Initial longmode iret.

VMM: SELM and VMM early HM init changes.

#ifdef the raw-mode force flags to find more code to #ifdef out.

IOM: Adding pVCpu to a lot of calls and moving the lookup caches from VM to VMCPU.

IEM: CR4 and CR3 fixes. Debugging hacks.

IEM and EM: debugging/hacking.

IEM: Fixed a copy&past bug in fnsave wrt FTW. Added a verification/rem kludge to STI.

IEM: Eflags fixes, added API variants that bypasses access handlers, ...

Disabled iret debugging.

IEM: IRET to V8086 (had to try). Set CPUM_CHANGED_FPU_REM. Added missing RIP advancing to fincstp and fdecstp.

Fixed fnstcw. Implemented fnsave and frstor.

iret: todo.

nit

IEM: Implemented WRMSR. Fixed mixed up src/dst in XADD.

IEM: Implemented SIDT, SGDT, SLDT and STR. Fixed LLDT and LTR mode checks. Fixed hidden selector handling bugs in selector loading and mode switching code. Fixed clobbering of high EBP bits in ENTER (16-bit stack). Changed MOVS to not use memcpy and flag the verifier if the src/dst areas are in overlapping in any important way.

IEM: Implemented SGDT and SIDT.

IEM: Working on new BIOS / NT...

IEM: Status code handling. PGM interface for R0 and RC.

IEM: Stats and more gentle stubs for unimplemented instructions.

IEM: Fixed iret problem in raw-mode - invalid selector data.

VMM: Fixed some selector arithmetic, introducing a new constand and renaming and old one to make things clearer. Also added CPUMGetGuestLdtrEx and make some (but not all) of SELM use this instead of shadow GDT.

VMM: Futher work on dealing with hidden segment register, esp. when going stale.

CPUM: Combined the visible and hidden selector register data into one structure. Preparing for lazily resolving+caching of hidden registers in raw-mode.

Doxygen, comment typos.

IEM: Research done by Michal fixed a todo.

IEM: fnstsw m16, ffree and ffreep, reimplemented fincstp and fdecstp.

fcomi, fcomip, fucomi and fucomip.

todo

IEM: Implemented fxch.

IEM: Implemented fldcw, fldenv fnstcw and fnstenv.

a little bug fix.

protected mode far call and far return.

Some cleaning up.

todo

fmul st0,m64r

IEM: fxsave & fxrstor.

fxsave + fxrstor is underways => laptop.

IEM: VERR_NOT_IMPLEMENTED -> VERR_IEM_INSTR_NOT_IMPLEMENTED or VERR_IEM_ASPECT_NOT_IMPLEMENTED.
