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