Hi, On the site I have noticed a number of issues. Most are easily fixed, but I'm not sure about this one.
On http://www.dragonflybsd.org/docs/goals.cgi Serializing tokens may also be used to protect threads from preempting interrupts that attempt to obtain the same token. This is a slightly different effect from the Big Giant Lock (also known as the MP lock), which does not interlock against interrupts on the same cpu. It is important to note that token atomicity is maintained through preemptive conditions, even though preemption involves a temporary switch to another thread. It is not necessary to enter a spl() level or critical section to preserve token atomicity. Weren't the spl set of functions removed? For the others, I have a patch almost ready. Trevor
