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