To make it easier to check what watermark updates are actually necessary, keep copies of the relevant bits that match the current hardware state. Also add DDB partitioning into hsw_wm_values as that's another piece of state we want to track. We don't read out the hardware state on init yet, so we can't really start using this yet, but it will be used later.

But a later patch in this series removes the memcmp again. So this is ok as-is.] Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> |
