Hi,
This serie is needed to enable current legacy virtio devices in a
cross-endian environment. Even though virtio-1.0 will address endianess
questions at the specification level, it is still in its early boot phase
and no code will be available before long (Rusty, please correct me if I am
wrong).
We have all the PPC KVM bits in 3.14 already. We have PPC QEMU patches
ready to be applied by Alexander, as soon as the common code gets in.
Anthony has already positively reviewed this serie. We have been testing
for some monthes... Now we are waiting for partners ! :)
Are the ARM people still interested in cross-endian virtio ? Are there
other people interested (Thomas for s390) ?
If so, please participate or we will have to wait for the new standard to be
finalized and implemented... :-\
Cheers.
