Hi -
Something maybe unrelated.... after inserting gator successfully get some kernel logs coming
[ 52.491528] CPU PMU: unable to set irq affinity (irq=0, cpu=0) [ 52.496351] CPU PMU: unable to set irq affinity (irq=0, cpu=0) ...
irq = 0 isn't looking very happy... are there more new DT properties we need somewhere to be compatible? Our actual pmu section just looks like this
pmu { compatible = "arm,cortex-a9-pmu"; interrupts = <0 98 0x4>, <0 99 0x4>; };
This isn't an area I have any knowledge in, sorry. But for what it's worth that looks the same format as vexpress pmu nodes. IRQs are obviously different, and the number of them match the number of CPUs.
This may be another side effect on the perf hacks of the changed IKS CPU pairing.
I don't intend to fix this unless someone has a strong need for it. I'm working on something to supersede those perf hacks, but it won't be ready immediately.
