[Qemu-devel] [PATCH 09/29] target-i386: add API to get dump info |
Date: |
Tue, 5 Jun 2012 14:24:48 -0300 |
From: Wen Congyang <address@hidden>
Dump info contains: endian, class and architecture. The next
patch will use these information to create vmcore. Note: on
x86 box, the class is ELFCLASS64 if the memory is larger than 4G.
