[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [Xen-devel] [patch] load 64-bit files with 32-bit tools
This patch allows 32bit libxc to grok 64bit files by:
- using 64bit types for addresses in struct domain_start_info
- uses stroull() so it can parse 64bit values
xc_hvm_build.c and xc_linux_build.c are effected because these
data-types are printed.
