More Intel Panther Lake Graphics Device IDs Added To Open-Source Linux Driver
Intel's Linux graphics driver engineers continue working on enabling support for the Xe3 integrated graphics premiering with next-gen Core Ultra "Panther Lake" SoCs. Today a number of additional PCI device IDs have been merged to the Mesa 25.2 code to reflect the growing family.
Prior to today there were eight PCI device IDs for Panther Lake (PTL) integrated graphics. Now with today's Git merge, it's up to 12 distinct PCI device IDs for integrated graphics on Panther Lake.
The device IDs simply identify the parts as "PTL" without describing any other characteristics of the graphics capabilities/tier. Not all twelve device IDs are necessarily for consumer-facing products but some could be reserved for engineering/pre-production models, tentative but not yet committed to models, etc.
With 12 Panther Lake graphics IDs, it's also interesting to note that for Lunar Lake is just three graphics IDs, five graphics IDs for Meteor Lake, and five graphics IDs for Arrow Lake. So it would appear that there are likely a greater number of different integrated graphics models to be found on different Panther Lake SoCs.
This Mesa merge adding the new Panther Lake IDs is also marked for back-porting to the current Mesa 25.1 stable series.
