Jérôme Duval bc5570ae60 kernel/x86: set initial user thread IOPL to zero User threads aren't supposed to be able to adjust the interrupt flag (IF). A few apps for instance DOSBox would just use the popf instruction and disable the flag, expecting the change to be ignored. Quote from the Intel manual: "The interrupt flag (IF) is altered only when executing at a level at least as privileged as the IOPL. If a POPF/POPFD instruction is executed with insufficient privilege, an exception does not occur, but the privileged bits do not change." fix #14711 Change-Id: I0519312c1151a1dd76541f60283c6c210a5b21a6 Reviewed-on: https://review.haiku-os.org/c/haiku/+/4046 Reviewed-by: Adrien Destugues <pulkomandy@gmail.com>		2021-06-04 15:56:33 +00:00

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!
