[PATCH 10/11] drm/i915: add pipe_htotal to struct skl_wm_params

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

 



With this one here we can finally drop the intel state structures from
the functions that compute watermark values: they all rely on struct
skl_wm_params now. This should help the watermarks code be a little
more clear on its intent and also match the spec a little bit more
with the carefully chosen names for its parameters.
