New opportunities in the linuxulator

Last weekend I committed some dummy-syscalls to the linuxulator in FreeBSD-current. I also added some comments to syscalls.master which should give a hint which linux kernel had them for the first time (if the linux man–page I looked this up in is correct). So if someone wants to experiment with a higher compat.linux.osrelease than 2.6.16 (as it is needed for a CentOS based linux_base), he should now get some kernel messages about unimplemented syscalls instead of a silent failure.

There may be some low-hanging fruits in there, but I did not really verify this by checking what the dummy syscalls are supposed to do in linux and if we can easily map this to existing FreeBSD features. In case someone has a look, please send an email to


Tuning guide in the wiki

In the light of the recent benchmark discussion, a volunteer imported the tuning man-page into the wiki. Some comments at some places for possible improvements are already made. Please go over there, have a look, and participate please (testing/verification/discussion/improvements/…).
