I think this series will mask the bug which is currently blocking staging propagating to master. I had some difficulty testing this, as the test box under my desk doesn't do PT and I didn't want to wait to book one out from the test lab. So I have executed only some of the new code in libxl. I would really appreciate review by a hypervisor expert on the main chunk of new code in libxl added in patch 9, which is where all the logic related to passthrough enabling and mode now resides. am 1 libxl: Offer API versions 0x040700 and 0x040800 r 2 xl: Pass libxl_domain_config to freemem(), instead of b_info r* 3 libxl: libxl__domain_config_setdefault: New function r* 4 libxl: libxl_domain_need_memory: Make it take a domain_config * 5 libxl: Move shadow_memkb and iommu_memkb defaulting into libxl a 6 libxl: Remove/deprecate libxl_get_required_*_memory from the API + 7 libxl: create: setdefault: Make libxl_physinfo info[1] + 8 libxl: create: setdefault: Move physinfo into config_setdefault + 9 libxl/xl: Overhaul passthrough setting logic a=acked; r=reviewed; m=message changed; *=patch changed; +=new patch tools/libxl/libxl.h | 24 +++++- tools/libxl/libxl_create.c | 174 ++++++++++++++++++++++++++++++++++--------- tools/libxl/libxl_dm.c | 7 +- tools/libxl/libxl_dom.c | 7 +- tools/libxl/libxl_internal.h | 13 +++- tools/libxl/libxl_mem.c | 69 +++++++++++++---- tools/libxl/libxl_types.idl | 5 +- tools/libxl/libxl_utils.c | 15 ---- tools/libxl/libxl_utils.h | 2 +- tools/xl/xl_parse.c | 82 ++------------------ tools/xl/xl_vmcontrol.c | 6 +- 11 files changed, 254 insertions(+), 150 deletions(-)
