230/* Surface update type is used by dc_update_surfaces_and_stream
231 * The update type is determined at the very beginning of the function based
232 * on parameters passed in and decides how much programming (or updating) is
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.
