RE: [openib-general] OFED-1.0-rc6 is available

2006-06-08 Thread Scott Weitzenkamp (sweitzen) 



The MTU change undos the changes for bug 81, so I have 
reopened bug 81 (http://openib.org/bugzilla/show_bug.cgi?id=81).
 
With rc6, PCI-X osu_bw and osu_bibw performance is bad, 
and PCI-E osu_bibw performance is bad.  I've enclosed some performance 
data, look at rc4 vs rc5 vs rc6 for Cougar/Cheetah/LionMini.
 
Are there other benchmarks driving the changes in rc6 
(and rc4)?

2006-06-08 Thread Roland Dreier 
Thanks... one further fix for Cisco gateways: sometimes the IsDM bit
is set on switch ports as well, so ibsrpdm should not be limited to
just CA ports.

Here's the patch, also on the trunk as r7836.

Roland did the fix on Trunk and I took it to OFED 1.0 branch.

 From the openib source tar ball in OFED RC6, it looks like
the SRP kernel changes (ulp/srp/ib_srp.c) in the trunk for
supporting Rev 10 targets have been included in RC6, but the 
corresponding changes to the userspace srptool--ibsrpdm
(userspace/srptools/src/srp-dm.c) for displaying the IO class
of the target have not been made part of RC6.

The changes to ibsrpdm were committed to the SVN repository trunk in 
revision number 7758.

Will the latest version of ibsrpdm make it to the next OFED release ?

Regards,
Ram

We also just found a bug in how ibsrpdm discovers Cisco/Topspin FC
gateways.  The patch is below, and is also checked in to the trunk as
svn rev 7803.  Please include this in OFED 1.0 final.
