The following dump-core patches changes its format into ELF, adds PFN-GMFN table, HVM support, and adds experimental IA64 support. - ELF format Program header and note section are adopted. - HVM domain support To know the memory area to dump, XENMEM_set_memory_map is added. XENMEM_memory_map hypercall is for current domain, so new one is created. and hvm domain builder tell xen its memory map. - IA64 support IA64 support is for only review. It doesn''t work because Xen/IA64 doesn''t support memory map hypercall. Subject: [PATCH 1/5]...

The changeset ''12803:df5fa63490f4da7b65c56087a68783dbcb7944f8'' added a new hypercall XENMEM_set_memory_map for specifying the e820 mapping. There was a small bug in the userspace side of this change though - the e820 mapping was specified based on the ''memory_static_min'' domain info parameter which means the memory map size is clamped to the value ''memory'' config opti...

I just built 4.3.0 in order to get > 2GB of RAM in domU with GPU passthrough without crashes. Unfortunately, the same crashes still happen. Massive frame buffer corruption on domU before it locks up solid. It seems the PCI memory stomp is still happening. I am using qemu-dm, as I did on Xen 4.2.x. So whatever fix for this went into 4.3.0 didn''t fix it for me. Passing less than 2GB

Hi, V6: The only change from V5 is in patch #6: - changed comment to reflect autoxlate - removed a redundant ASSERT - reworked logic a bit so that get_page_from_gfn() is called with NULL for p2m type as before. arm has ASSERT wanting it to be NULL. Tim: patch 4 needs your approval. Daniel: patch 5 needs your approval. These patches implement PVH dom0. Patches 1 and 2
