Modified Files:
src/sys/arch/xen/xen: hypervisor.c
Log Message:
Workarounds for amazon's Xen 4.2 version, still present on some instances:
- It doens't provides an xencons, so allow HVM_PARAM_CONSOLE_PFN to fail
- the xen clock is not fully functionnal, so don't try to use it if
HVM_PARAM_CONSOLE_PFN failed.
- it doesn't have XEN_HVM_CPUID_VCPU_ID_PRESENT so fall back to ci_acpiid
as ci_vcpuid in this case.
It also doesn't support the per-CPU event callback; so fix the fallback
to global vector (don't try to register more per-cpu vector)
Should fix port-amd64/55543
