237  * going to be done during the call.
238  *
239  * UPDATE_TYPE_FAST is used for really fast updates that do not require much
240  * logical calculations or hardware register programming. This update MUST be
241  * ISR safe on windows. Currently fast update will only be used to flip surface
242  * address.
243  *
244  * UPDATE_TYPE_MED is used for slower updates which require significant hw
245  * re-programming however do not affect bandwidth consumption or clock
246  * requirements. At present, this is the level at which front end updates
247  * that do not require us to run bw_calcs happen. These are in/out transfer func
248  * updates, viewport offset changes, recout size changes and pixel depth changes.
249  * This update can be done at ISR, but we want to minimize how often this happens.
250  *
251  * UPDATE_TYPE_FULL is slow. Really slow. This requires us to recalculate our
252  * bandwidth and clocks, possibly rearrange some pipes and reprogram anything front
253  * end related. Any time viewport dimensions, recout dimensions, scaling ratios or
254  * gamma need to be adjusted or pipe needs to be turned on (or disconnected) we do
255  * a full update. This cannot be done at ISR level and should be a rare event.
256  * Unless someone is stress testing mpo enter/exit, playing with colour or adjusting
257  * underscan we don't expect to see this call at all.
