There is nowhere else that unsets it (or makes sense to unset it), we have to do it here, or otherwise it will never be unset. This has actually been broken since the new scheduler was merged many years ago; the old scheduler (which had more complex logic here) unset this flag correctly. This oversight mostly did not cause obvious problems: while the scheduler would be invoked unnecessarily on every single interrupt, that would be a minor performance downturn at most. But there is one other effect: since we can only reenable interrupts after invoking the scheduler, "post_interrupt_callback"s of threads were not invoked most of the time. The main user of "post_interrupt_callback"s is the profiler, which uses them to trigger buffer flushes back to userland. Since they were not invoked, the buffer would quickly fill up and then no more results would be recorded. Thus, this fixes #16345.
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!
