[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [Xen-changelog] [xen-unstable] HVM cleanups:
# HG changeset patch
# User kfraser@xxxxxxxxxxxxxxxxxxxxx
# Node ID 6a26f49d3b168496025d3c7edf3861d503c3a03b
# Parent d19b8542865b61ae884f49340ca5dbaddadc2973
HVM cleanups:
1) make vmx/svm time functions hvm common, since they are actually the same.
2) move hvm_send_assist_req from platform.c to hvm.c.
2) rename VMX MSR context switch functions to make them more readable.
3) misc coding style clean ups.
