If we just use the kernel entry time, then the pre-syscall tracing routine (with a debugger message send) will be counted in the syscall's runtime. Makes the output of timing in strace and strace -c much more accurate, however it won't include the "syscall overhead" (time spent in the syscall entry routines, etc.) But we already can't account for time spent in the userland-to-kernel transition, so that should probably be measured some other way if knowing it is desired. In fact, on architectures which used the generic syscall dispatcher (e.g. RISC-V), this is the behavior that already existed. So this just makes x86 consistent with them.

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!
