At the Intel Tech Tour in Arizona, an entire slot was devoted to talking up their next-gen IPU to be found with upcoming high-end Panther Lake laptops. This was in addition to the main Intel Panther Lake / Xe3 presentation. IPU product marketing manager Tomer Rider presented on their IPU7.5 tech, but unfortunately like we have seen with Intel's IPU tech since Alder Lake, there are user-space binary blobs involved...

A few months back it was brought up on the Intel driver mailing list around SR-IOV support for Panther Lake's Xe3 graphics. This goes along with Intel open-source Linux driver developers being quite busy on SR-IOV support for Battlemage dGPUs as part of their Project Battlematrix. Unfortunately, I wasn't provided any answer at Intel Tech Tour in Arizona whether SR-IOV support will be found with all Panther Lake SKUs or reserved for select offerings...

Fedora 43 is working its way toward release in the coming weeks and is now going through a very late change. A change was announced and accepted today for increasing the size of the /boot partition. This is driven by the ever-increasing number of firmware files needed for different devices to function under Linux with open-source drivers. A large motivator to this change was the very large and growing NVIDIA GPU firmware file sizes for Nouveau and the future Nova driver...
