I'm not a huge fan of this for a couple reasons. The first is that
it introduces a subtle semantic change. Previously, timers always
ran before bottom halves whereas after this change, timers may run
after some bottoms halves but before others.

This adds notifiers for phys memory changes: a set of callbacks that
vhost can register and update kernel accordingly. Down the road, kvm
code can be switched to use these as well, instead of calling kvm code
directly from exec.c as is done now.

This patch against qemu upstream adds notifiers hook which lets backends
get notified on memory changes, and converts kvm to use it. It survived
light testing. Avi, could you please take a look at this patch?
Thanks!

So, it appears that this is not the case for many platforms: bridge
itself does a byteswap to make devices behind it work according to spec,
but this does not apply to programming bridge itself.
This seems common on BE platforms, this is why qemu has

The fpcr_exc_status, fpcr_exc_mask, and fpcr_dyn_round fields
are stored in softfloat.h format for convenience during

Yes, but I think how you program your host to pci bridge is platform specific,
