- It is not enabled for a long time and is actually a dead code. - It was tested before that it is actually slower on < 15 year old hardware so it have no any benefits. Modern CPUs have no problems with simple memory filling/copying operations. More complex acceleration operations are not supported in current accelerant driver API. - It breaks double buffering and reintroduce flickering artefacts. - It is incompatible with antialiased CPU drawing because GPU framebuffer memory reading is deadly slow and reading is required for alpha blending operation. So rendering buffer must be in CPU memory, offscreen GPU buffer can't be used. - Hardware 2D acceleration for modern hardware is usually implemented using generic GPU rendering APIs such as OpenGL or Vulkan.

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 documentation
The main piece of documentation that still needs work are the API docs (found
in the tree at docs/user). Just find an undocumented class, write
documentation for it, and submit a patch.
