Augustin Cavalier 58436dc467 kernel/x86: Handle overflows in apic_timer_set_hardware_timer.
This is relatively harmless in all cases except where the lower 32 bits
are all zeroes, as in that case we would never get a timer interrupt.
In all other cases we would just time out too soon, and the timer
interrupt handler would reschedule.

We need to add clock divisor selection to this module so that we can
be sure that at least reasonably-sized timeouts (a few seconds, e.g.)
will not overflow 32 bits, though.

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!
