Xen devel - May 2007 - [PATCH]NVRAM support for IA64

Hi Ian:

         Attachment is a patch implementing NVRAM for IA64. The patch is
to add patch through libxc to remove the file access dependency from
Qemu. The patch doesn''t touch much of the

 common code, just add a hook in Xend and a HVM param in XEN. Hope your
comments on it. Nvram is important to IA64, we got many requirements for
it.Thx:-)

 

Good good study,day day up ! ^_^

Wing, this patch is great improvement.
Without this patch, we cannot boot windows 2008,
and also cannot boot windows 2003 automatically on ia64.
 
I have a few commens.
PERROR doesn''t print messages because libxc doesn''t have
terminal.
So it is better to pass Error codes (e.g. ENOMNT, EPERM..) to xend so
xend can catch exceptions and, as a result, it puts error messages in
xend.log.

How do you like this?

Keir and Ewan, do you have any other comments?

Best Regards,

Akio Takebe

[Zhang, Xing Z(Wing)] 
PERROR prints messages to xend-debug.log. It also transfers the errno variable
to readable string and prints it to dom0''s console.
There are lots of usages of PERROR in libxc lib, so I think PERROR works fine.
Thanks for your comments.
