Hi,
When inserting the ib_srp module, the ehca driver spits out an error:
ehca D.001.DQDXYCB-P1-C9: PU0007 EHCA_ERR:ehca_alloc_fmr unsupported
fmr_attr->page_shift=9
The following code in ib_srp.c is causing it:
/*
* Use the smallest page size supported by the HCA, down to a
* minimum of 512 bytes (which is the smallest sector that a
* SCSI command will ever carry).
*/
srp_dev->fmr_page_shift = max(9, ffs(dev_attr->page_size_cap) - 1);
Looks like we should be setting props->page_size_cap.
Compile tested only, I dont have any IB attached storage.
