Package: irqbalance
Version: 1.0.6-3
Severity: normal
Dear Maintainer,
On upgrade recently I was asked irqbalance/oneshot which says:
_Description: Would you like to balance the IRQs once?
irqbalance can run in one shot mode, where the IRQs are balanced only
once. This is advantageous on hyperthreading systems such as the Pentium
4, which appear to be SMP systems, but are really one physical CPU.
I'm not running on a Pentium 4 so it is unclear to me what the recommended
answer would be.
Please can you include some advice for non-Pentium 4 users such as "On systems
SMP other than Pentium 4 it is recommended to say [yes|no*]" (*deleting as
appropriate).
When answering "yes" when does this balancing occur, only once at boottime
perhaps?
It's also not all that clear what the behaviour of answering "no" to this
question is. Is it to not do any balancing at all or to balance repeatedly? I
suspect the latter but I'm not sure and it's not clear from the text.
It might also be useful to point out that users of UP systems can safely
uninstall irqbalance altogether. (assuming that's true, I think it is).
Perhaps irqbalance/enable and irqbalance/oneshot could be combined into a
choice selection:
When to balance interrupts. Pentium 4 users should say "once", all other
SMP systems should say "regularly", UP systems should say "never".
* Never balance interrupts
* Balance interrupts once (on boot?)
* Balance interrupts regularly
(these would correspond to enable,oneshot == "no,na", "no,yes", "no,no"
respectively). I'd recommend running the text past the en i18n list for style
and clarity, since my proposal isn't worded very well IMHO (hopefully you get
the gist though).
Thanks,
Ian.
