* Don't bother aligning the PCI memory addresses; they will already be aligned, and even if by some mystery they aren't, map_physical_memory should be able to handle that. This greatly simplifies the code. * Use one pointer and then four different offset fields instead of four different pointers. This is what DragonFlyBSD and FreeBSD do; it's a negligible loss in performance (or none at all, depending on arch and compiler) as it requires only one more add, and greatly clarifies the code as to what's going on. * Remove (both previously and now) unused fields from the header. * Compute runtime and doorbell register offsets correctly (there was a missing bitmask.) This is how it's done on FreeBSD and DragonFlyBSD. * Actually write the high bits of the DMA addresses. Checked against FreeBSD and DragonFlyBSD. * Tweak error message. Possibly fixes the "invalid bus space memory access" crash, but I don't have any hardware that occurs on so I couldn't check. Tested in VMware, VirtualBox, and on a ThinkPad E550 (Broadwell).
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

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.
