280  *
281  * UPDATE_TYPE_FAST is used for really fast updates that do not require much
282  * logical calculations or hardware register programming. This update MUST be
283  * ISR safe on windows. Currently fast update will only be used to flip surface
284  * address.
285  *
286  * UPDATE_TYPE_MED is used for slower updates which require significant hw
287  * re-programming however do not affect bandwidth consumption or clock
288  * requirements. At present, this is the level at which front end updates
289  * that do not require us to run bw_calcs happen. These are in/out transfer func
290  * updates, viewport offset changes, recout size changes and pixel depth changes.
291  * This update can be done at ISR, but we want to minimize how often this happens.
292  *
293  * UPDATE_TYPE_FULL is slow. Really slow. This requires us to recalculate our
294  * bandwidth and clocks, possibly rearrange some pipes and reprogram anything front
295  * end related. Any time viewport dimensions, recout dimensions, scaling ratios or
296  * gamma need to be adjusted or pipe needs to be turned on (or disconnected) we do
297  * a full update. This cannot be done at ISR level and should be a rare event.
298  * Unless someone is stress testing mpo enter/exit, playing with colour or adjusting
299  * underscan we don't expect to see this call at all.
