While working on xenstore-stubdom live update support I came across
some really unpleasant code using struct start_info even when running
in PVH mode.
Especially suspend/resume was doing some crazy stuff, including
overwriting the initial struct hvm_start_info partially.
This series is hiding struct start_info from PVH code. This didn't
result in any runtime error, but in future I'll need to access struct
hvm_start_info some time after boot, so I need to get that fixed.
Tested especially with xl suspend/resume and xl save/restore in PV and
in PVH mode.
Juergen Gross (6):
suspend: drop crazy pfn handling for PVH
setup: drop parameter from map_shared_info()
x86/pv: remove global start_info
console: drop parameter from get_console()
xenbus: drop parameter from get_xenbus()
x86/pv: make start_info_ptr PV-only
Before I even try: Does this series interfere in any way with the kexec one,
and hence may need re-basing on top of that (which I've pushed a minute ago)?
I'm not aware of any possible conflict.
Juergen
