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