Hi Greg/Christoph,
Can we leave it meanwhile till we'll find a general solution (for the upcoming
kernel) ?
I guess we can somehow generalize the P2P initialization process for PPC and
leave it empty for now for other archs.
Or maybe we can find some other solution (sysfs/configfs/module param), but it
will take time since we'll need to work closely with the IBM pci guys that
wrote this code.
We do not keep code without in-tree users around, especially not if
we have a better API with in-tree users.
AFAICS the only thing you'll need is to wire up the enable/disable
calls.
I guess you're right, but we still need to know the time frame we have
here since this should be tested carefully on the P9 hardware.
Are we ok with working on a solution during kernel-5.3 cycle ?
