Augustin Cavalier d836d5447a kernel/thread: Cache kernel stacks.
Instead of creating and destroying kernel stack areas on every thread
creation and destruction, use the object_cache's constructor/destructor
hooks to create areas when cached objects are created, and reuse them.

This avoids the last major cause of kernel map flushing during compile
jobs, however it's not as much of a performance improvement as I'd hoped,
seeming to be within the realm of noise (within a VM anyway.) On systems
like VirtualBox where ICIs are much more expensive, it may be a bigger
performance boost.

Haiku

Homepage | Mailing Lists | IRC Channels | Issue Tracker | API docs

Haiku is an open-source operating system that specifically targets personal computing. Inspired by the BeOS, Haiku is fast, simple to use, easy to learn and yet very powerful.

Goals

  • Sensible defaults with minimal configuration required.
  • Clean, clear, concise code.
  • Unified desktop environment.

Trying Haiku

Haiku provides pre-built nightly images and release images. Haiku is compatible with a large variety of hardware, but in case you don't want to "take the plunge" and install Haiku on bare metal, you can install it on a virtual machine (VM) instead. If you've never used a VM before, you can follow one of the "Emulating Haiku" guides.

Compiling Haiku

See ReadMe.Compiling.

Contributing

Haiku is a meritocratic open source project with a large variety of tasks. Even if you can't write code, you can still help! Haiku needs designers, (technical) writers, translators, testers... Get involved and help out!

Contributing code
