Linux 5.19 preliminary support for Intel Raptor Lake-P
In the recent Linux 5.19 kernel, the developers introduced 24 new lines of code, the addition of which includes support for the Intel Raptor Lake-P graphics driver in PCI ID, which has now been added to the i915 graphics driver. Similar to the previous positioning of Alder Lake-P, Raptor Lake-P will target mainstream and high-performance laptops.
From a driver perspective, Intel Raptor Lake-P behaves the same as Alder Lake-P, following the same driver code path, so developers enabled very little code to add support for the Raptor Lake-P graphics driver. The first batch of PCI IDs involving Raptor Lake-P included 0xA720, 0xA721, 0xA7A0, 0xA7A1, 0xA7A8, and 0xA7A9, which doesn’t mean there will be six different graphics configurations for Raptor Lake-P, some may be left over for engineering samples or possible future variants.
The Raptor Lake-S patch has already appeared in the Linux 5.19 kernel before, and this addition of support for the Raptor Lake-P graphics driver means that it is one step closer to Intel’s new generation of platforms. Intel is expected to launch Raptor Lake in late 2022, still using the Intel 7 process, and the flagship model will be equipped with 8 Performance Cores and 16 Efficient Cores, with a total of 24 cores and 32 threads. Unlike Alder Lake, the performance core of Raptor Lake will be changed from the Golden Cove architecture to the Raptor Cove architecture, while the energy efficiency core will follow the current Gracemont architecture.
