Hi
I have newly joined to this mailing list. Pardon me for bothering =
with my silly questions.
I was not able to get this information from the official website. I know =
this can be determined by looking at the source code, but it is going to =
be too much of a work. I have this option as a last resort.
I know that FreeBSD 5.x supports fine grained locking and 4.x just =
supports coarse grained / giant kernel lock. I would like to know the =
capabilities of SMP implementation in 4.x (say 4.8). I am interested to =
know -
- are the interrupts shared between the multiprocessors?
- what algorithm is used to decide which processor services which =
interrupt ?
- does it distributes the interrupts based on the processor load ?
- does it distributes the software interrupt processing also ?
- how the user level processes are scheduled to run on other processors =
?
- can the user process be run on a particular processor ?=20
- how the processor affinity is taken into consideration ?
Can any of you give some pointers to the SMP capability list in FreeBSD =
4.x ?
It would be great if you can also point me to some design / =
implementation of SMP architecture in FreeBSD 4.x.=20
Thanks a lot,
VBabu
