Both level_zero and the shared/source/os_instance/linux only use the deprecated i915 linux driver and uapi-i915 support instead of the xe linux driver and uapi-xe support. The runtime has some support for xe but that support has to been used in the implementation.

shared/source/os_interface/linux/ioctl_helper.h implements IoctlHelperI915; IoctlHelperUpstream, IoctlHelperImpl, IoctlHelperPrelim20 all use the i915 support but there does not exist an IoctlHelperXe that uses xe support.

Hi @ct-clmsn
IoctlHelperXe implements IoctlHelper interface and it is available in default driver build. In case of xe linux driver (like for Lunarlake/Battlemage) we don't call any i915-specific ioctl

@JablonskiMateusz ah wait, I see IoctlHelperXe and specifically the Drm::setupIoctlHelper has a conditional that checks for xe. My apologies!
