## Features to finish/implement

* IPF/PF deprecation in favour of NPF
   - TODO: docs, what features to add to NPF ...
* ATA/NCQ
   - variants of [[!template id=pr number=48214]] "clearing WDCTL_RST failed" during boot - problem still present on some configurations
   - ~~[[!template id=pr number=52783]] parallel fsck hangs during boot of 8.99.[5678]~~ (done)

   - ~~[[!template id=pr number=53183]] System stops servicing I/O requests and eventually deadlocks~~ (done)
* UBC using direct map - removal of pmap_enter()/pmap_remove()/pmap_update() for read()/write()-based I/O
   - [[!template id=pr number=54759]] (vm.ubc_direct deadlock when read()/write() into mapping of itself)
   - [[!template id=pr number=53124]] (FFS is slow because pmap_update doesn't scale)
   - confirmed working on amd64, alpha, aarch64
   - ~~need sysctl to more easily turn on, will be left off by default for 9.0~~ (done)
* XEN AVX working
   - ~~[[!template id=pr number=50332]] AVX instructions don't work but OSXSAVE flag is set~~ (done)
* ZFS
* ~~~kASan for amd64~~~ (done)
* ~~~kASan for aarch64~~~ (done)

## Nice to have

* ~~~arm: GENERIC kernel config for armv7 boards.~~~ (done)
* ~~~arm64: Support for servers following SBSA/SBBR standards~~~ (done)
* ~~~updated graphics drivers~~~ (done)
* PVHVM and PVH
* ~~~ARM64 ACPI~~~ (done)
* WireGuard
