Public bug reported:
[Impact]
Google has requested a backport of some irdma fixes to the Noble HWE
kernel, which will receive them via questing:linux-gcp.
[Fix]
Target patches:
2529aead5167 ("RDMA/irdma: Use CQ ID for CEQE context")
2b7c2ba1308a ("RDMA/irdma: Add enum defs for reserved CQs/QPs")
5c3f795d17dc ("RDMA/irdma: Remove fixed 1 ms delay during AH wait loop")
01dad9ca37c6 ("RDMA/irdma: Fix SRQ shadow area address initialization")
Some additional patches may be needed for these to apply/build cleanly.
[Test Plan]
This is a relatively small patchset. We will boot test the kernel on a
bare-metal IDPF machine, but this should be low risk enough to be moved
through to production without super stringent testing otherwise.
[Regression potential]
The changes requested are isolated to the Intel RDMA driver, so
regressions should only be possible when using Intel RDMA and will
likely manifest as unexpected network behavior or kernel crashes/hangs
during specific network activities. These patches are close to the
upstream tip, so some follow-up fixes may appear.
