multiqueue for storage (scott/justin)

WANT

dd on steroids (adrian)
- TRIM sparse areas
logical volume manager (adrian)
less friction out of the box (a.k.a., 'sane defaults') (gjb)
- less tuning required (e.g. see calomel.org for nicely done system settings and user hints)
- presettings for server/enterprise
- more auto-tuning
- MINIMAL kernel
- /usr/local
- vendor-ports documentation (Bdrewery)
- bsd.ports.local.mk
network stack backpressure
crash dump over LAN
can’t savecore from (4k-n)
bhyve pxe boot
pre-alloc large chunks of RAM
- config.mem from DPDK
dedicated cpus
- more timer / IRQs more easily
USB device wiring
- deterministic ordering of usb devices when attached (or a way to control that behavior)
ethtool-like (adrian)
- cloudflare netmap
- VLAN on vf
start SMP earlier (more MSI-X)
BIG-LITTLE
- ISA-compatible heterogeneous compute
- scheduling
- power/thermal constraints
sparsify the middle of a file (targeted truncate aka trim for files)
vmsplice
vimage
multiple simultaneous network stacks (work in process)
ethernet proper support for jumbo frames
- fail more gracefully
- more optimally-performant ring sizing
- graceful fallback to smaller clusters
- best practices implemented in a model driver
- checksum offload support for netmap
- KNI driver for DPDK
trim zfs (aka ‘real’ trim) - better zfs support for trim
- panic if destroy TRIMS 1 large range due to dead man timer
- C++ support for ztfs tools
large memory system support (berman)
better KLO/CTF integration
- load SUNW?
kload
Machine readable DTrace output (gnn)
Increase MNAMELEN (max length of a mount point), breaks ABI (already done in projects/ino64, just needs sync/polish/review)
