278  * going to be done during the call.
279  *
280  * UPDATE_TYPE_FAST is used for really fast updates that do not require much
281  * logical calculations or hardware register programming. This update MUST be
282  * ISR safe on windows. Currently fast update will only be used to flip surface
283  * address.
284  *
285  * UPDATE_TYPE_MED is used for slower updates which require significant hw
286  * re-programming however do not affect bandwidth consumption or clock
287  * requirements. At present, this is the level at which front end updates
288  * that do not require us to run bw_calcs happen. These are in/out transfer func
289  * updates, viewport offset changes, recout size changes and pixel depth changes.
290  * This update can be done at ISR, but we want to minimize how often this happens.
291  *
292  * UPDATE_TYPE_FULL is slow. Really slow. This requires us to recalculate our
293  * bandwidth and clocks, possibly rearrange some pipes and reprogram anything front
294  * end related. Any time viewport dimensions, recout dimensions, scaling ratios or
295  * gamma need to be adjusted or pipe needs to be turned on (or disconnected) we do
296  * a full update. This cannot be done at ISR level and should be a rare event.
297  * Unless someone is stress testing mpo enter/exit, playing with colour or adjusting
298  * underscan we don't expect to see this call at all.
