Hi David, I initially introduced this feature as a VFIO feature IOCTL. Maintainers didn't like that idea and favored a new IOCTL for TPH. I will be sending out the V2 with that change sometime this week (pending review internally). I sent out the DPDK patch before so that I can link this patch to the cover letter of the kernel patch to show them that there is a real user-space use case for this feature. V1 is now largely outdated here is the link https://lore.kernel.org/kvm/20250401235225.ga327...@ziepe.ca/T/#me73cf9b9c87da97d7d9461dfb97863b78ca1755b Thanks. --wathsala
