Do some memory map related changes/fixes for PVH mode: - Prefer the memory map delivered via start-info over the one obtained from the hypervisor. This is a prerequisite for Xenstore-stubdom live-update with rising the memory limit. - Fix a bug related to ballooning in PVH mode: PVH Xenstore-stubdom can't read its target memory size from Xenstore, as this introduces a chicken-and-egg problem. The memory size read from the hypervisor OTOH includes additional "special" pages marked as reserved in the memory map. Those pages need to be subtracted from the read size. - Fix a bug in ballooning code in PVH mode when using memory beyond a RAM hole in the memory map Changes in V3: - minor comment for patch 3 addressed Changes in V2: - added patch 4 - addressed comment regarding patch 3 Juergen Gross (4): mini-os: take newest version of arch-x86/hvm/start_info.h mini-os: prefer memory map via start_info for PVH mini-os: fix number of pages for PVH mini-os: fix bug in ballooning on PVH arch/x86/mm.c | 23 ++++---- balloon.c | 18 ++---- e820.c | 83 ++++++++++++++++++++++++--- include/e820.h | 6 ++ include/x86/arch_mm.h | 2 + include/xen/arch-x86/hvm/start_info.h | 63 +++++++++++++++++++- 6 files changed, 163 insertions(+), 32 deletions(-) -- 2.35.3

If you need someone to commit then please CC committers@ and this will land in my inbox. Cheers, -- Julien Grall

He doesn't seem to be interested any more, unfortunately... Juergen

He doesn't seem to be interested any more, unfortunately... And really, with no other indication so far, I've been skipping mini-os patches on the assumption that Wei would be looking after them. Wei, if you can't do so anymore, could you please explicitly indicate so? Jan
