Why is irqbalance package so out of date?

2012-06-15 Thread Stephen Hemminger
Irqbalance project has moved to http://code.google.com/p/irqbalance/
The current Debian package is back at 0.56 (over 2yrs old)
and upstream is now at version 1.0.3

The project home page moved. The old one is out of date.

Maybe I need to take a trip over and knock on the door...

I will be happy to get involved; upstream irqbalance is on my list
of things that are broken and needs to be fixed. Will try and get a hold
of past contributors to figure out what is happening. I know there was
talk of fixing it and integrating Holger's irqd logic.

I haven't looked in detail at current version. But the older versions had
dynamic policy and depended on making assumptions about which device had
which irq (by looking at /proc/interrupts), and polling for network activity.
What it was trying to do might have been a good idea in old i386 days but
was getting horribly confused with all the types of multiqueue drivers etc.

The ideal program would be state driven, handle power management (use less
cores when not busy), and be dynamically user configurable, and solve world
hunger...
