sys/i386/i386/mp_machdep.c:
sys/i386/include/cpu.h:
- Introduce two new CPU hooks for initialization and resume
purposes. This allows us to get rid of the XENHVM ifdefs in
mp_machdep, and also sets some hooks into common code that can be
used by other hypervisor implementations.
sys/amd64/conf/XENHVM:
sys/i386/conf/XENHVM:
- Remove these configs now that GENERIC has builtin support for Xen
HVM.
sys/kern/subr_smp.c:
- Make sure there are no pending IPIs when suspending a system.
sys/x86/xen/hvm.c:
- Add cpu init and resume vectors that are called from mp_machdep
using the new hooks.
- Only clear the vcpu_info mapping data on resume. It is already
clear for the BSP on a cold boot and is set correctly as APs
are started.
- Gate xen_hvm_init_cpu only to systems running under Xen.
sys/x86/xen/xen_intr.c:
- Gate the setup of event channels only to systems running under Xen.
