nvme: fix the NVME_CMD_EFFECTS_CSE_MASK definition

2023-01-04T10:28:52Z

[ Upstream commit 685e6311637e46f3212439ce2789f8a300e5050f ] 3 << 16 does not generate the correct mask for bits 16, 17 and 18. Use the GENMASK macro to generate the correct mask instead.

Mark them as unsigned so that we don't need extra casts, and define them relative to cdword0 instead of requiring extra shifts. Signed-off-by: Christoph Hellwig Reviewed-by: Sagi Grimberg Reviewed-by: Hannes Reinecke

nvme: handle the persistent internal error AER

2022-08-02T23:14:47Z

In the NVM Express Revision 1.4 spec, Figure 145 describes possible values for an AER with event type "Error" (value 000b). For a Persistent Internal Error (value 03h), the host should perform a controller reset. Add support for this error using code that already exists for doing a controller reset. As part of this support, introduce two utility functions for parsing the AER type and subtype. This new support was tested in a lab environment where we can generate the persistent internal error on demand, and observe both the Linux side and NVMe controller side to see that the controller reset has been done.

nvme: use struct group for generic command dwords

This will allow the trace event to know the full size of the data intended to be copied and silence read overflow checks. Reported-by: John Garry Suggested-by: Christoph Hellwig Signed-off-by: Keith Busch Signed-off-by: Christoph Hellwig

nvme: add support for TP4084 - Time-to-Ready Enhancements

2022-05-18T16:54:17Z

Add support for using longer timeouts during controller initialization and letting the controller come up with namespaces that are not ready for I/O yet. We skip these not ready namespaces during scanning and only bring them online once anoter scan is kicked off by the AEN that is set when the NRDY bit gets set in the I/O Command Set Independent Identify Namespace Data Structure. This asynchronous probing avoids blocking the kernel boot when controllers take a very long time to recover after unclean shutdowns (up to minutes).
