    drm/i915: Don't bypass LRC on CHV · 9571b190
    Ville Syrjälä authored
    The docs are unclear as usual, so it's not clear whether LRC should be
    bypassed, performed normally or GRC code should be used as the LRC code.
    Some old docs stated that LRC bypass ought to be used, more recent ones
    no longer say that. Some docs indicated that we could use GRC as the LRC
    code on CHV, but the BIOS doesn't do that, so let's not do it either.
    
    Besides to enable LRC bypass properly, I believe we should set the bit
    already before deasserting cmnreset.
