eHCA is very close from the interrupt generation and handling perspective,
so yes, could be an issue there as well.

Guessing the values does not work, because of the handle s

Well, this testcase is already pretty close to the bare minimum
what's needed to run IB/RDMA queues.
You can compare this to for example ibv_rc_pingpong
Hello,
if get_user_pages is used on a hugetlb vma, and there was no previous write
to the pages,
follow_hugetlb_page will call
ret = hugetlb_fault(mm, vma, vaddr, 0),
although the page should be used for write access in get_user_pages.
We currently see this when testing Infiniband on ppc64 with e

When kexec is fully supported kdump should work out of the box
as for any other ethernet card (if you load the right eth driver).
There's nothing specific to kdump you have to handle in

With todays hypervisor and todays pagesizes and today
the HEA device driver
alone.
It could also affect any other networking cards on POWER (e1000,s2io...).
Paul, Michael, Arndt, what is your opinion here?

What would you suggest, add two additional LL QP types, or change something

in libibverbs and kernel ib core?
We think we can get along quit
