Jim906 342a1b221b FAT: revise using code from FreeBSD
* Rewrite most hook functions, modeling many after FreeBSD hooks and
  making use of support functions ported from FreeBSD. As it stands
  now, most of the FreeBSD driver files are present with minimal
  changes, with a pseudo-BSD compatability layer added to make them
  work in Haiku. Performance is not what it could be if the BSD code
  was rewritten to interface directly with the Haiku kernel, but under
  the current approach the driver might be easier to maintain in terms
  of porting future FreeBSD bugfixes.
* Add support for FAT in userlandfs. Aside from being useful for
  debugging, the userlandfs module provides better filename support
  for characters that are not in code page 850, because it can link
  libiconv.
* Update the fat_test.sh script to use dosfstools to format the tested
  device, instead of the internal dosfs_initialize hook. The script
  is written to test specific cluster sizes, but the initialize hook
  still does not support user-specified cluster sizes.
* Coding guidelines: lightly-modified BSD files and lightly-modified
  original Haiku driver files have not been revised to adhere to the
  Haiku style guidelines. For BSD files, this is meant to make it
  easier to compare with the FreeBSD repository when merging future
  FreeBSD patches. For existing driver files, this is to highlight the
  functional changes made in this change request (I can submit a
  separate patch later to clean up style in these files). Also, some
  #include lines are not alphbetized (they are instead ordered like
  they would be in FreeBSD, because one header relies on another).

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!
