Nothing ported from anywhere else. Basic implementation.* Not yet connected to the build, interrupts are not yet functional (it currently just polls at 100hz for testing), some additional error handling is needed, and we will need ioctl support and a userland utility to do various administrative tasks like formatting.* Near full header spec keyed in including the bits we don't use (yet).* Full SMP BIO interface and four different queue topologies implemented depending on how many queues the chipset lets us create. The best is ncpus * 4 queues, i.e. (low, high priority) x (read, write) per cpu. The second best is just (low, high priority) x (read, write) shared between all cpus. Extremely low BIO overhead. Full strategy support and beginnings of optimizations for low-latency I/Os (currently a hack).* Initial testing with multiple concurrent sequential dd's on a little samsung nvme mini-pcie card: 1.2 GBytes/sec 16KB 2.0 GBytes/sec 32KB 2.5 GBytes/sec 64KB List of files: /dflybsd-src/sys/dev/disk/nvme/Makefile Sun, 05 Jun 2016 02:35:29 +0000 Matthew Dillon <dillon@apollo.backplane.com>
