[[!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

## Bug Bountys

PRs in the above list marked with /!\ are show stoppers 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 ...
   - 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)
* ~~~kASan for amd64~~~ (done)
* ~~~kASan for aarch64~~~ (done)
* compiler-rt in the base with enabled features for Clang/LLVM
* 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
* [Revert pmax switch to common MIPS bus_space and bus_dma](

## Nice to have

* gcc 8+ from a sanitizers point of view
* ~~~arm: GENERIC kernel config for armv7 boards.~~~ (done)
* ~~~arm64: Support for servers following SBSA/SBBR standards~~~ (done)
* ~~~updated graphics drivers~~~ (done)
* ~~~ARM64 ACPI~~~ (done)
* WireGuard
* expand x86 intr masks to allow up to 56 interrupts per CPU and hence 40 MSI/MSI-X on cpu0

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

* merge pgoyette-compat
* 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)
