[PATCH v2 0/1] vfio-ccw: Enable transparent CCW IPL from DASD [QEMU]

Posted by Jared Rossi 4 years ago

Remove the explicit prefetch check when using vfio-ccw devices.
This check does not trigger in practice as all Linux channel programs
are intended to use prefetch.

QEMU part to make use of the corresponding kernel patch posted here:

https://lore.kernel.org/kvm/20200506212440.31323-1-jrossi@linux.ibm.com/

It is no longer required to force the PFCH flag, but the option is
still supported.
