[Qemu-devel] [PATCH 2/3] s390: Added check for unsupported parameters of dump-guest-memory |
Date: |
Thu, 28 Mar 2013 17:35:59 +0100 |
From: Ekaterina Tumanova <address@hidden>
Check for the 'begin' and 'length' parameters of dump-guest-memory monitor
command (not supported for s390) was placed into arch specific function:
arch_check_parameter. The stub of this function is added to target-i386
directory for compatibility reasons.
