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