PXP (Protected Xe Path) is an i915 component, available on GEN12 and newer platforms, that helps to establish the hardware protected session and manage the status of the alive software session, as well as its life cycle. changes from v9: - Patch #3 - change comments from "Gen12+" to "Gen12 and newer" - Patch #4,#9 - Remove inclusion of intel_gt_types.h from intel_pxp.h - Patch #10 - Modify internal get/set-protected-context functions to not return -ENODEV when setting PXP param to false or when running on pxp-unsupported hw or when i915 was built with CONFIG_PXP off - Patch #11 - increase timeout when waiting in intel_pxp_start as firmware session startup is slower right after boot.
