[[!meta title="NetBSD 9.0 preliminary tasklist"]]

## PRs worth fixing

(carried over unclosed PRs from [[netbsd8]])

* ~~[[!template id=pr number=53053]]: non-MULTIPROCESSOR hangs building Go~~ (still reproducable with newer go?)  
  [[!template id=pr number=53173]]: "go test net/http" locks up the machine (both PRs tied /!\ )
* [[!template id=pr number=53016]]: Clock not stable /!\
* [[!template id=pr number=53017]]: Kernel panics every now and then with "fpusave_lwp: did not" message
* [[!template id=pr number=53155]]: Wedge after <12h uptime when >2 bnx network interfaces in use /!\
* [[!template id=pr number=53161]]: ATF test runs leave a rump_server process around
* [[!template id=pr number=53286]]: hdaudio(4), iwm(4) and rtsx(4) detections fail in UEFI case /!\
* [[!template id=pr number=53291]]: GPT prevents installation

Regression since [[netbsd8]]:

* [[!template id=pr number=53128]]: Boot says "default boot twice, skipping..."
* [[!template id=pr number=54074]]: Test cases ending in 32 fail on sparc64 since jemalloc update
* [[!template id=pr number=54089]]: vax installer does not boot (init dies)
* [[!template id=pr number=54093]]: Recent test regressions on sparc
* [[!template id=pr number=54300]]: lib/libutil/t_snprintb test regression on sparc
* [[!template id=pr number=54345]]: kernel diagnostic assertion "xfer != NULL" in wdc.c


## Bug Bountys

PRs in the above list marked with /!\ are likely hard and critical, and have a bug bounty of $100 attached.
If you find a solution for one of the marked issues that leads to closing of the PRs, we will get
in touch with you.

## 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=52614]] qemu virtual CD-ROM reports read errors since recent wdc changes~~ (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=53124]] (FFS is slow because pmap_update doesn't scale)
   - all known issues fixed - 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)
* ~~~compiler-rt in the base with enabled features for Clang/LLVM~~~ (done)
* LVM mirror target
* ~~~add NVMM~~~ (done)
* ~~~plug kernel pointer leaks~~~ (done)
* ~~~fix Nouveau, some GPUs stopped working after the update~~~ (done)
* umb(4) confirmed working with network traffic

## 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
* expand x86 intr masks to allow up to 56 interrupts per CPU and hence 40 MSI/MSI-X on cpu0
  [[http://mail-index.netbsd.org/current-users/2018/12/01/msg034728.html]]

## Nice to have, but likely won't be finished on time

* ~~~merge pgoyette-compat~~~ (done)
* address failing ptrace(2) tests, cover the remaining scenarios (there are planned ~2k ATF tests total for the elementary functionality)
* rework semantics of threading operations in ptrace(2)

## Abandoned for 9.0

* ~~~gcc 8+ from a sanitizers point of view~~~ (abandoned)
