jimharris requested changes to D17708: Put a workaround in for command timeout malfunctioning.

I think you mean "completion timeout", not "command timeout" - in both the commit message and some of the comments.

jimharris accepted D16570: nvme(4): Add bus_dmamap_sync() at the end of the request path.

This looks good so far. Definitely a big improvement over what was there previously. I'll think about this some more, if there are any other syncs that we're missing.

jimharris added a comment to D16570: nvme(4): Add bus_dmamap_sync() at the end of the request path.

Sorry - I was looking at a much older version of the nvme(4) driver. You are correct - PRPs are getting synced as part of the queuemem_map.

jimharris added a comment to D16570: nvme(4): Add bus_dmamap_sync() at the end of the request path.

I'm sure you already know this, but you only need to sync before we ring the doorbell for I/O submission. The device never writes to the PRP list - it only reads it.

jimharris added a comment to D16570: nvme(4): Add bus_dmamap_sync() at the end of the request path.

In nvme_payload_map, can you also sync the tr->prp_dma_map? Using the same qpair->dma_tag.

jimharris added a comment to D16570: nvme(4): Add bus_dmamap_sync() at the end of the request path.

I think we have to sync the PRP lists too. Give me a minute and I'll send you some pointers.

Nope, haven't tested it, don't have a NVME card to test with. There have between people expressing a desire to use it on PowerPC. Regardless, it should be usable on any little endian platform, and any bugs for big endian can be squashed as they are tested.

Technically the BWD (stands for Briarwood - an Atom-based SOC) dev IDs should be treated the same as BDX (Broadwell) DE (aka Xeon D). I have no Briarwood hardware to test on though. But should not hurt to just add those device IDs anyways.

I would rather see the full patch here instead of just this workaround to get BDX-DE initialized. Otherwise recovering from channel hangs after initialization will not be possible.

sys/modules/Makefile needs to be updated too, such that _ioat is only defined when MACHINE_CPUARCH == amd64. I forgot to mention this when I commented on files.amd64 and NOTES.
