Yes. OFW dosn't provide interrupt handling, so all device drivers are
polled. Therefore the poor IO performance.=20

There is support for the Firepower machines only. I use this code as
development bais for the PowerStack II machine dependent code. [1] Most
code can be reused but e.g. the PCI config is completely different on
Firepower and PowerStack II. I figured out that PCI config read / write
stuff today, now I have to implement it... Other nice things as
interrupt handling are still waiting for me.=20
So there is somthing going on, but it will take some time to finish.=20

[1] My old CS professor said in my 1. semester: "Good programmers write
good code. Very good programmers copy good code." At least I try to be a
very good programmer. ;-)=20
