[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [Xen-changelog] Rationalise x86 CRn guest state into a ctrlreg array in the per-vcpu
ChangeSet 1.1751, 2005/06/24 11:46:24+01:00, kaf24@xxxxxxxxxxxxxxxxxxxx
Rationalise x86 CRn guest state into a ctrlreg array in the per-vcpu
context structure. Most noticeably this means the pt_base field has
gone away -- replaced by ctrlreg[3] (CR3). VCPU_guest_stts is also
gone -- it was never arch-independent anyway.
