- clockattach(): Allow multiple calls when running in Qemu. Anything after this first one is ignored, but this gives us a change to use a clock source provided by the VM directly, rather than relying on a more expensive hardware emulation. - Add cpu_initclocks_secondary(), to handle clock setup on secondary CPUs, if needed. - Allow us to use the WTINT PALcode call in cpu_idle() to idle in a lower power state (Qemu's PALcode supports this). - Use the Qemu per-cpu set-alarm-rel call as the hardclock interrupt source. In Qemu environments, reduce hz to 50 (rather than the default 1024) to give the clock a snowball's chance when running on a host system with hz=100. XXX We have to manually re-calculate tick and tickadj. There should be MI code to do this for us. Also in Qemu environments, let hardclock() drive the sched clock by setting schedhz=0.
NetBSD
NetBSD is a free, fast, secure, and highly portable Unix-like Open Source operating system. It is available for a wide range of platforms, from large-scale servers and powerful desktop systems to handheld and embedded devices.
Building
You can cross-build NetBSD from most UNIX-like operating systems. To build for amd64 (x86_64), in the src directory:
./build.sh -U -u -j4 -m amd64 -O ~/obj release
Additional build information available in the BUILDING file.
Binaries
Testing
On a running NetBSD system:
cd /usr/tests; atf-run | atf-report
Troubleshooting
- Send bugs and patches via web form.
- Subscribe to the mailing lists. The netbsd-users list is a good choice for many problems; watch current-users if you follow the bleeding edge of NetBSD-current.
- Join the community IRC channel #netbsd @ freenode.
