Title:
32 GT/s PCI link speeds reporting "Unknown speed" in sysfs
Status in linux package in Ubuntu:
Incomplete
Status in linux source package in Focal:
Incomplete
Bug description:
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">
