    drm/i915/xelpg: Call Xe_LPG workaround functions based on IP version · f7696ded
    Matt Roper authored
    Although some of our Xe_LPG workarounds were already being applied based
    on IP version correctly, others were matching on MTL as a base platform,
    which is incorrect.  Although MTL is the only platform right now that
    uses Xe_LPG IP, this may not always be the case.  If a future platform
    re-uses this graphics IP, the same workarounds should be applied, even
    if it isn't a "MTL" platform.
    
    We were also incorrectly applying Xe_LPG workarounds/tuning to the
    Xe_LPM+ media IP in one or two places; we should make sure that we don't
    try to apply graphics workarounds to the media GT and vice versa where
    they don't belong.  A new helper macro IS_GT_IP_RANGE() is added to help
    ensure this is handled properly -- it checks that the GT matches the IP
    type being tested as well as the IP version falling in the proper range.
    
    Note that many of the stepping-based workarounds are still incorrectly
    checking for a MTL base platform; that will be remedied in a later
    patch.
    
    v2:
     - Rework macro into a slightly more generic IS_GT_IP_RANGE() that can
       be used for either GFX or MEDIA checks.
    
    v3:
     - Switch back to separate macros for gfx and media.  (Jani)
     - Move macro to intel_gt.h.  (Andi)
