Subject: bug: sdnvme blindly initializes conf.nmach submission queues
Date: Wed, 14 Oct 2020 19:30:33 -0700 [thread overview]
Message-ID: <CAH_zEu4+2asD-aY4ZBRgiNw6EB9sQOibOZJC+za4TuERzVGN3w@mail.gmail.com> (raw)
i have new SB-RKTQ4-1TB nvme disks.
the 9front kernel fails to initialize the disk because sdnvme attempts
to create one submission queue per CPU, but my ryzen 1700X has 8c/16t
and the disk only has 8 completion queues and 8 submission queues:
root@abacus:/home/mischief# nvme get-feature /dev/nvme1n1 -f 0x7
get-feature:0x7 (Number of Queues), Current value:0x070007
thus, my disks don't work at all in 9front.
