Ping? On 11/02/2015 06:51 AM, Juergen Gross wrote: The Xen hypervisor supports starting a dom0 with large memory (up to the TB range) by not including the initrd and p2m list in the initial kernel mapping. Especially the p2m list can grow larger than the available virtual space in the initial mapping. The started kernel is indicating the support of each feature via elf notes. This series enables grub-xen to do the same as the hypervisor. Tested with: - 32 bit domU (kernel not supporting unmapped initrd) - 32 bit domU (kernel supporting unmapped initrd) - 1 GB 64 bit domU (kernel supporting unmapped initrd, not p2m) - 1 GB 64 bit domU (kernel supporting unmapped initrd and p2m) - 900GB 64 bit domU (kernel supporting unmapped initrd and p2m) Juergen Gross (6): xen: factor out p2m list allocation into separate function xen: factor out allocation of special pages into separate function xen: factor out allocation of page tables into separate function xen: add capability to load initrd outside of initial mapping xen: modify page table construction xen: add capability to load p2m list outside of kernel mapping grub-core/lib/i386/xen/relocator.S | 47 ++-- grub-core/lib/x86_64/xen/relocator.S | 41 ++- grub-core/lib/xen/relocator.c | 22 +- grub-core/loader/i386/xen.c | 521 +++++++++++++++++++++++++---------- grub-core/loader/i386/xen_fileXX.c | 7 + include/grub/xen/relocator.h | 6 +- include/grub/xen_file.h | 3 + 7 files changed, 446 insertions(+), 201 deletions(-) _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxx http://lists.xen.org/xen-devel
