Public bug reported: Our NCCL software uses the sysfs to populate the attached topo.xml file. Several of the entries should report "32 GT/s", but they're saying "Unknown speed" instead. For instance:
<pci busid="0000:0c:00.0" class="0x020700" vendor="0x15b3" device="0x1021" subsystem_vendor="0x15b3" subsystem_device="0x0082" link_speed="Unknown speed" link_width="16"> The 5.4 kernel is missing the following commit: https://lore.kernel.org/all/1581937984-40353-2-git-send-email- yangyic...@hisilicon.com/ ** Affects: linux (Ubuntu) Importance: Undecided Assignee: Ian May (ian-may) Status: New ** Affects: linux (Ubuntu Focal) Importance: Undecided Assignee: Ian May (ian-may) Status: New ** Also affects: linux (Ubuntu Focal) Importance: Undecided Status: New ** Changed in: linux (Ubuntu) Assignee: (unassigned) => Ian May (ian-may) ** Changed in: linux (Ubuntu Focal) Assignee: (unassigned) => Ian May (ian-may) -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1970798 Title: 32 GT/s PCI link speeds reporting "Unknown speed" in sysfs Status in linux package in Ubuntu: New Status in linux source package in Focal: New Bug description: Our NCCL software uses the sysfs to populate the attached topo.xml file.
