(It seems I can reuse that line for all posts about the deprecation notices :-) ) While IVSHMEM was enabled (as it was the default) I never heard of any users of what we provided so far. But that is expected considering that not all qemu bits are landed either. Since it will follow the process of "deprecation notice -> grace period -> ABI bump" on removal, I think packaging and consuming applications should be fine. I'd agree to Hiroshi that, if really needed a clean re-implementation more properly separated from EAL likely is the best way to go. I think it is a good change to drop rather complex code in favor of stabilizing the main paths: Acked-by: Christian Ehrhardt <christian.ehrhardt@canonical.com> Christian Ehrhardt Software Engineer, Ubuntu Server Canonical Ltd On Wed, Jul 27, 2016 at 9:08 PM, Jan Viktorin <viktorin@rehivetech.com> wrote: > On Wed, 20 Jul 2016 18:35:46 +0200 > Thomas Monjalon <thomas.monjalon@6wind.com> wrote: > > > There was a prior call with an explanation of what needs to be done: > > http://dpdk.org/ml/archives/dev/2016-June/040844.html > > - Qemu patch upstreamed > > - IVSHMEM PCI device managed by a PCI driver > > - No DPDK objects (ring/mempool) allocated by EAL > > > > As nobody seems interested, it is time to remove this code which > > makes EAL improvements harder. > > > > Signed-off-by: Thomas Monjalon <thomas.monjalon@6wind.com> > > Acked-by: David Marchand <david.marchand@6wind.com> > > Acked-by: Maxime Coquelin <maxime.coquelin@redhat.com> > > Acked-by: Jan Viktorin <viktorin@rehivetech.com >
