This worked a treat, thanks. My network performance is better
now, but still not what it was. The same TFTP transfer now takes
71 seconds, so about 50% slower than on the 3.0 kernel. Applying the
second [unnamed] patch (arch/arm/mach-omap2/cpuidle34xx.c) made no difference.
And does a CONFIG_PM=n kernel get you back to your v3.0 performance?
Correct.
I am interested in having PM working as I'm designing a battery powered
portable unit, so I need to keep pursuing this.
So do I. :)
Note: I noticed that when I built with CONFIG_PM off and no other
changes, my EHCI USB didn't work properly. Should this be the case?
Probably not, but haven't tested EHCI USB. I've Cc'd Felipe to see if
he has any ideas why EHCI wouldn't work with CONFIG_PM=n.
Thanks
