RE: About Intel I/OAT support in open-iscsi

2009-03-16 Thread Shyam_Iyer

I don't think open-iscsi needs to support that.
 
You just load the relevant I/O AT modules. This should get automatically
loaded if the system BIOS enables I/O AT (requires chipset support).
 
Once you have done that the network has a performance boost and you can
do all you want from normal network things including open-iscsi.
 
Thanks,
Shyam

Subject: About Intel I/OAT support in open-iscsi


Hi,

I need Intel I/OAT support in open-iscsi.  I'm now using RHEL 5.3.  I
cannot tell if RHEL 5.3 kernel supports I/OAT or not by reading its
source code.  It would be great help if anyone could answer the
following questions for me.

1) Do open-iscsi modules in RHEL 5.3 kernel support I/OAT?
2) Does open-iscsi support I/OAT now?  If so, from which version?

Thank you!

Regards,
Simon

[patch]: kernel: add missing ';' in backport patches

2009-03-16 Thread Dotan Barak

Add missing ';' in backport patches.
When enabling debug in compilation, the lack of semicolon caused a compilation
failures on older kernels.

(since i have problems with my mail client, i added this patch as an attachment)
