Hi,
What is the precise meaning of the ver0 and ver1 bits in the L4 thread ids?
Cheers, Daniel

one is just the hi value the otehr is the low value. Versionning applies to tasks. Threads just have the version number of the task they run it.

one is just the hi value the other is the low value. Versioning applies to tasks. Threads just have the version number of the task they run it.
Why are they separate? I havent seen the MIPS implementation actually touch the ver1 bits.

I think they were seperate in the Intel for efficiency reasons, mips seems to just use the intel register layout. Mips uses the full version bits internally in the TTable.
