The Ominpath adapter driver fails to load the ppc64le platform due to invalid PCI setup. I am recommending this patch to pcie.c which better aligns configuration with linux PCI subsystem functions. It also fixes the issue. Hopefully, this motivates a change. I am new to the group, so if I am short content, I may need more direction than your experienced members.
Thanks for the patch. We'll work with you offline to get it into the right format for Doug to accept.
