[PATCH 1/2] drm/i915: Bump skl+ wm blocks to 11 bits

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

 



From: Ville Syrjälä <ville.syrjala@xxxxxxxxxxxxxxx>

On icl the plane watermark blocks field is 11 bits. Bump our define to
match so that readout won't ignore the extra bit. We can safely do this
for older platforms too since the unused bits are hardwired to zero.
