Augustin Cavalier 778706215d app_server: Drop gfxcpy and implement some TODOs about checking for graphics memory.
We still do not know if the accelerant buffers are graphics memory or not,
but in my testing (on the VESA driver), the only time I could get _CopyRect
to be called was where the buffer was in fact not graphics memory.
So that should provide a performance improvement there.

On the other end of things, this should resolve unaligned video memory
access problems on RISCV, and potentially other platforms, as gfxcpy32
did not attempt to align pointers; it should also improve performance
as memcpy will usually be faster than our custom gfxcpy here.

Most of this code has not been touched since 2006 or so.

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!
