CPUM,IEM: Expose GuestFeatures and HostFeatures (exploded CPUID), making IEM use it. Early XSAVE/AVX guest support preps.

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.

VMM: Added VMCPU_FF_UNHALT force-flag.

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

Moving CPUMCPU about...

VMCPU: Added a iHostCpuSet field to go with the idHostCpu one. This allows for better GIP time & TSC code in raw-mode context.

Added an official way of implementing a HLT/MWAIT like port on a device (for use with VMSVGA).

dtrace library fixes/hacks.

DIS: #6251: AVX / VEX instructions support (two byte instructions only) and some fixes to the other tables.

VMM: Fixed potential bug in AMD-V NMI injection when interrupt shadowing is in effect, renamed INHIBIT_NMIS to BLOCK_NMIS to match Intel specs.

VMM: Fix NMI handling.

VMM/EM: Reschedule halted VCPUs if NMI/SMI shows up.

TM: Add the same TSC offset to each VCPU when pausing/resuming (not yet enabled).

VMM/GIM: More bits for Hyper-V implementation.

VMM/GIM: Mapping of GIM MMIO2 regions and Hyper-V provider work.

GIM: Skeleton, work in progress.

VMM/HMVMXR0: MSR optimizations for world-switch of 64-bit guests.

More doxygen fixes.

vm.h: Doxygen.

VMM/VMMR0: Preemption hooks implemented and enabled for Solaris and Linux hosts.

VMM: More debugging related stuff.

VMM/HM: Dispatch host NMIs on Intel. Added separate STAM counter for host NMIs with the necessary changes to old, new VT-x, AMD-V code.

build fixes

VMM, recompiler: Purge deprecated macros.

VMM: Optimized 64-bit host VT-x world-switch.

List near, unassemble, hyper register and more tiny debugger fixes.

VMM: Fix for HM_PROFILE_EXIT_DISPATCH.

VMM: Introduced VMCPUSTATE_STARTED_HM for indicating that we're between HMR3Enter and HMR3Leave. Added HMIsInHwVirtCtx and VMMIsLongJumpArmed methods/macros.

VMM: SELM and VMM early HM init changes.

Do HMR3Init first in vmR3InitRing3 so the other components can skip raw-mode bits during init.

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

IOM: Preparing to use read/write critsect.

Ring-1 compression patches, courtesy of trivirt AG: - main: diff to remove the hwvirt requirement for QNX - rem: diff for dealing with raw ring 0/1 selectors and general changes to allowed guest execution states - vmm: changes for using the guest's TSS selector index as our hypervisor TSS selector (makes str safe) (VBOX_WITH_SAFE_STR ) - vmm: changes for dealing with guest ring 1 code (VBOX_WITH_RAW_RING1) - vmm: change to emulate smsw in RC/R0 (QNX uses this old style instruction a lot so going to qemu for emulation is very expensive) - vmm: change (hack) to kick out patm virtual handlers in case they conflict with guest GDT/TSS write monitors; we should allow multiple handlers per page, but that change would be rather invasive

PDMCritSectRw: Early morphing stage - untested, ring-3 only.

Alignment.

VMM/VMMAll, VMMR3: forceflags for updating CR3 and PAE PDPEs.

VMM: HM cleanup.

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

VMM: Switcher and TRPM fixes wrt hypervisor traps and tstVMM.

VMMSwitcher: Drop the unused assembly switcher functions taking guest or host contexts as arguments.

CPUMCTX++: Rearranging the CPUMCTX structure in preparation of some hidden selector register improvments.

vmm/vm.h: comment typo.

Working on making DTrace grok VM+CPUM and VMCPU+CPUMCPU.

Working on DTrace lib files.

More dtrace library stuff. On 64-bit solaris dtrace can now grok the library files (point it to them using the -L parameter).

Tweaks for DTrace.

SUPDrv,VMM: Tracepoints in raw-mode.

Added counters so that VT-x exit stats add up.

VMM/PDM: Some simple tracepoint infastructure.

VMM: Make most of the tracing optional so we don't have to be afraid of adding lots more.

build fixes.

IEM: fxsave & fxrstor.

VMM,INTNET: Addressing unused variable warnings.

vm.h: build fix

VMM: Renamed VM::fRawR0Enabled and VM::fRawR3Enabled, inverting their meaning.

VMM: Check for VMCPU_FF_PDM_CRITSECT in R0 and RC.

TM: Simplified the virtual sync timers by requiring changes to be done while holding the virtual sync lock. This means we can skip all the pending states and move timers on and off the active list immediately, avoiding the problems with timers being on the pending-scheduling list. Also made u64VirtualSync keep track of the last time stamp all the time (when under the lock) and thus really making sure time does not jump backwards.

vm.h: Alignment fix (32-bit hosts).

IOM,PDMCritSect: Extended PDMCritSectEnter to handle rcBusy=VINF_SUCCESS as a request to call ring-3 to acquire a busy lock. Implemented device level locking in the MMIO code.

PDM: Implemented the NOP critical section.

Try to fix build

VMM,SUPDrv: Created DBGFTrace.

PGMNotifyNxeChanged: Another try.

PGM: relax some assertion added earlier today so they'll survive reset and guru mediations.

IEM: Initial commit, work in progress.

PCI: refactoring, further IOMMU work

PCI: per-VM initialization (for IOMMU domains)

VMM/REM: Made .remstep work to some degree (might skip interrupts/traps).

fix OSE
