Intel Alder Lake P Linux Graphics Support Sent Out - Gen12 Xe + XE_LPD Display

While for months already Intel has been volleying Linux driver patches around Alder Lake S, today they began publishing their graphics driver support patches for Alder Lake P.

Alder Lake P is a hybrid CPU architecture like Alder Lake S while S is for the desktop parts and P is for mobile. The most striking difference with the Alder Lake P enablement is indicating that these processors feature the new "XE_LPD" display block, version 13 of Intel's display capabilities.

It just so happened earlier today that was covered in more details with Intel Sends Out New Linux Driver Patches For "XE_LPD" v13 Display Hardware. Alder Lake P is now the first confirmed Intel platform featuring that new XE_LPD display block while the graphics processor is still a Xe Gen12 design.

Of the initial 56 patches for the Alder Lake P open-source graphics support, much of that is tieing into the XE_LPD display code with the rest of the Gen12 graphics code being in common with ADL-S.

There are 18 PCI IDs added as graphics parts for Alder Lake P. Granted, some IDs may be reserved for pre-production / engineering models or otherwise reserved for future but currently unplanned variants. Those Alder Lake P graphics IDs include 0x46A0, 0x46A1, 0x46A2, 0x46A3, 0x46A6, 0x46A8, 0x46AA, 0x462A, 0x4626, 0x4628, 0x46B0, 0x46B1, 0x46B2, 0x46B3, 0x46C0, 0x46C1, 0x46C2, and 0x46C3.

The initial 56 patches providing the Alder Lake P support for the Intel kernel graphics driver can be found via the patchwork. Based on the timing that initial Alder Lake P graphics support will likely be introduced with the Linux 5.13 kernel this summer.
