Similar to Panther Lake's new NPU getting ready for Linux with the firmware binaries now upstreamed, this Sunday there were new versions of the Xe3_LPD firmware pushed to the de facto repository for Linux firmware/microcode assets. This is presumably the new Intel graphics firmware that's considered production-ready for the Panther Lake laptops expected to soon launch.
The new firmware drops included Xe3LPD DMC 2.33 and Xe3LPD_3002 DMC 2.28 .
Now that these binaries are in linux-firmware.git, they will get picked up by Linux distribution vendors for easy distribution as part of the different "linux-firmware" packages shipped in Linux distributions.
The Intel Panther Lake Linux support appears to be in largely good shape if using Linux 6.18+ and Mesa 25.3+, at least from my external monitoring. We'll know more about any support/feature caveats and the Linux performance of Panther Lake once being able to get my hands on Panther Lake laptop hardware in 2026.
