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- [email protected]/ ** 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 Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1970798 Title: 32 GT/s PCI link speeds reporting "Unknown speed" in sysfs To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1970798/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
