Hi Amir,
have you any news about bugs 2027 "SDP not respecting # SGEs as reported
from HW" and 2028 "SDP should support fastreg mrs"?
When those bugs will be fixed, I will test the NE020 cards performance
with SDP protocol and I will compare SDP and TCP.
Keep in touch,
Andrea Gozzelino
INFN -
It should be a simple fix and I plan to do soon - just add yourself as
CC in bugzilla - that way I won't forget to notify you.

ok - actually I used it in an early version of SDP before changing to FMR...

Thank you very much.
I check the status of 2027 and 2028 bugs.

Andrea, Please open a bug at bugzilla (https://bugs.openfabrics.org) -
so that you will be notified as soon as I will fix SDP not use FMR if
not supported.
As to fastreg_mrs support - I don't know this mechanism. Do you mean FRWR?

And 2028 opened to request fastreg support.

Hey Amir,
I don't think this helps because sdp_add_device() will not add rdma
devices that fail to create fmr pools.
So I guess you could key off of fmr pool failures and set
sdp_zcopy_thresh to 0 and allow the device to be used?
But what we really need is sdp support for fastreg_mrs as an
One more thing - Please open a bug regarding the num_sge limitation at:

Hi,
FMR are being used only in a special mode called ZCopy.
You could disable this mode by setting the module paramter
sdp_zcopy_thresh to 0, or by issuing:
# echo 0 > /sys/module/ib_sdp/parameters/sdp_zcopy_thresh
This means that you won't get the benefits of Zero-copy.
