Subject: [Qemu-devel] The issue about parameters(uint64) of a device are treated as signed long int.
Date: Fri, 31 Jul 2015 16:28:10 +0800 [thread overview]
Message-ID: <55BB319A.2010906@suse.com> (raw)
Hi all,
Because qemu uses strtoll to parse string in parse_str function of
qapi/string-input-visitor.c, I'd like to know why the parameters of
scsi-hd device which are specified as uint64(says wwn) are getting
interpreted as signed long int's instead
e.g:
# qemu-system-x86_64 -device scsi-hd,?
......
scsi-hd.wwn=uint64
......
Does the highest bit of wwn value have special meaning and it must be a
zero?
Thanks in advance,
Lin
