PGMHandler.cpp@ 45357

Last change on this file since 45357 was 45276, checked in by vboxsync, 12 years ago

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
