Linux 5.19:  Preliminary support for Intel Raptor Lake-P CPU


In the recent Linux 5.19 kernel, the developers introduced 24 new lines of code, the addition of which includes support for the 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, Raptor Lake-P behaves the same as Alder Lake-P and follows the same driver code path, so developers can add support for Raptor Lake-P graphics drivers with very little code enabled. program support.

The first batch of PCI IDs involving Raptor Lake-P includes 0xA720, 0xA721, 0xA7A0, 0xA7A1, 0xA7A8, and 0xA7A9.

This does not mean that Raptor Lake-P will have six different graphics configurations, some may be reserved for engineering samples or Versions left behind by 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.

Linus Torvalds recently released the initial version of Linux 5.18, the latest kernel is a milestone for the Linux community, providing manufacturers and users with extensive support and expansion.

The new code for this release focuses on two areas, one is adding AMD’s graphics drivers for the new hardware, and the other is an update to Intel’s performance monitoring event table.
