ibv_reg_mr works fine as long as the shared region is in RAM. However, if I change the memory region to the physical memory on a PCI device the call to ibv_reg_mr fails. What should I be doing to register a physical memory region?
In searching through this forum I've seen some patches relating to reg_io_mr/dereg_io_mr. However, I don't see those changes in the 1.5.2 ofed sources. I had hoped to try applying the patches myself but the structure of the unchanged code in the patches appears to be different than the 1.5.2 ofed sources. Is there another, more recent, code base that I should be using? Thank you in advance for your time and help! -Brian PS. My apologies if this appears posted twice. I waited a couple of hours for the original to post and it didn't - despite seeing later posts appear. -- To unsubscribe from this list: send the line "unsubscribe linux-rdma" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
