A look at the PyPy 2.0 release
I have a further question about shared IRQs in the RT tree. When saying that devices sharing an IRQ also share a thread, do you mean only the top halves, or all of the processing?
If it is the latter, isn't that a serious limitation? After all tasklets from devices sharing an IRQ can run simultaneously on different CPUs.
A question about threaded IRQs

Each softirq has its own thread. This lets you prioritize the softirqs as well, where you can not do that with vanilla linux. You can raise the network softirqs over the other softirqs.

As usual the great articles combined with the incredible level of the other subscribers makes LWN more than worthwhile...
