I was his advis= or on that thesis so I got to watch it roll out as it happened.

uvm replaced the machvm in netbsd.=C2=A0

F= or a time, Chuck set it up to run in parallel with the existing VM. You cou= ld start a process and pick which vm it used. For a while, it defaulted to = the existing one. Then, at some point, it defaulted to uvm. Then, at some p= oint, the old one was removed.

more here:


via search terms=C2=A0
uvm rep= laces machvm netbsd

chuck was a long time cont= ributor to netbsd IIRC, but last time we talked, he was using Linux.

These days I know he's hacking on FreeBSD's stor= age stack with me at work :). I think he's still a netbsd contributor. = I see his name in the commit log often..=C2=A0
