sys/amd64/include/cpufunc.h:
sys/amd64/amd64/pmap.c:
Move invltlb_globpcid() into cpufunc.h so that it can be
used by the Xen HVM version of tlb shootdown IPI handlers.
sys/x86/xen/xen_intr.c:
sys/xen/xen_intr.h:
Rename xen_intr_bind_ipi() to xen_intr_alloc_and_bind_ipi(),
and remove the ipi vector parameter. This api allocates
an event channel port that can be used for ipi services,
but knows nothing of the actual ipi for which that port
will be used. Removing the unused argument and cleaning
up the comments surrounding its declaration helps clarify
its actual role.
sys/amd64/amd64/mp_machdep.c:
sys/amd64/include/cpu.h:
sys/i386/i386/mp_machdep.c:
sys/i386/include/cpu.h:
Implement a generic framework for amd64 and i386 that allows
the implementation of certain CPU management functions to
be selected at runtime. Currently this is only used for
the ipi send function, which we optimize for Xen when running
on a Xen hypervisor, but can easily be expanded to support
more operations.
sys/x86/xen/hvm.c:
Implement Xen PV IPI handlers and operations, replacing native
send IPI.
sys/amd64/include/pcpu.h:
sys/i386/include/pcpu.h:
sys/i386/include/smp.h:
Remove NR_VIRQS and NR_IPIS from FreeBSD headers. NR_VIRQS
is defined already for us in the xen interface files.
NR_IPIS is only needed in one file per Xen platform and is
easily inferred by the IPI vector table that is defined in
those files.
sys/i386/xen/mp_machdep.c:
Restructure to more closely match the HVM implementation by
performing table driven IPI setup.
