233  * going to be done during the call.
234  *
235  * UPDATE_TYPE_FAST is used for really fast updates that do not require much
236  * logical calculations or hardware register programming. This update MUST be
237  * ISR safe on windows. Currently fast update will only be used to flip surface
238  * address.
239  *
240  * UPDATE_TYPE_MED is used for slower updates which require significant hw
241  * re-programming however do not affect bandwidth consumption or clock
242  * requirements. At present, this is the level at which front end updates
243  * that do not require us to run bw_calcs happen. These are in/out transfer func
244  * updates, viewport offset changes, recout size changes and pixel depth changes.
245  * This update can be done at ISR, but we want to minimize how often this happens.
246  *
247  * UPDATE_TYPE_FULL is slow. Really slow. This requires us to recalculate our
248  * bandwidth and clocks, possibly rearrange some pipes and reprogram anything front
249  * end related. Any time viewport dimensions, recout dimensions, scaling ratios or
250  * gamma need to be adjusted or pipe needs to be turned on (or disconnected) we do
251  * a full update. This cannot be done at ISR level and should be a rare event.
252  * Unless someone is stress testing mpo enter/exit, playing with colour or adjusting
253  * underscan we don't expect to see this call at all.
