[PATCH 1/2] drm/i915/ats-m: add ATS-M platform info

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



ATS-M is a server platform based on Xe_HPG and Xe_HPM, but without
display support.  From a driver point of view, it's easiest to just
handle it as DG2 (including identifying as PLATFORM_DG2), but with the
display disabled in the device info.
