In preparation for Panther Lake laptops shipping in early 2026, after Intel appears to have largely wrapped up work on the Linux driver enablement they are now ensuring the necessary firmware bits are out in time.
The latest upstream Linux kernel appears to be in good shape for Intel Panther Lake laptops from the Xe3 integrated graphics to all of the other key functionality. But even with open-source drivers, as is the case with much of today’s hardware, various firmware blobs are necessary for operation.
Since this summer the GuC and HuC firmware blobs needed by the Xe3 graphics on Panther Lake have been upstreamed to linux-firmware.git. Added this week is the new firmware binary needed for the Intel Integrated Sensor Hub “ISH” with Panther Lake.
The Intel Integrated Sensor Hub is the low-power co-processor for offloading sensor processing tasks like motion, biometric, and other inputs via HID. Since Lunar Lake, a ~0.9MB firmware blob is needed for the Intel Integrated Sensor Hub to function.
With this commit the needed ISH firmware is now in place for Panther Lake laptops.
