 442 *
 443 * UPDATE_TYPE_FAST is used for really fast updates that do not require much
 444 * logical calculations or hardware register programming. This update MUST be
 445 * ISR safe on windows. Currently fast update will only be used to flip surface
 446 * address.
 447 *
 448 * UPDATE_TYPE_MED is used for slower updates which require significant hw
 449 * re-programming however do not affect bandwidth consumption or clock
 450 * requirements. At present, this is the level at which front end updates
 451 * that do not require us to run bw_calcs happen. These are in/out transfer func
 452 * updates, viewport offset changes, recout size changes and pixel depth changes.
 453 * This update can be done at ISR, but we want to minimize how often this happens.
 454 *
 455 * UPDATE_TYPE_FULL is slow. Really slow. This requires us to recalculate our
 456 * bandwidth and clocks, possibly rearrange some pipes and reprogram anything front
 457 * end related. Any time viewport dimensions, recout dimensions, scaling ratios or
 458 * gamma need to be adjusted or pipe needs to be turned on (or disconnected) we do
 459 * a full update. This cannot be done at ISR level and should be a rare event.

 461 * underscan we don't expect to see this call at all.

3260 * dc_capture_register_software_state() - Capture software state for register programming
3261 * @dc: DC context containing current display configuration
3262 * @state: Pointer to dc_register_software_state structure to populate
3263 *
3264 * Extracts all software state variables that are used to program hardware register
3265 * fields across the display driver pipeline. This provides a complete snapshot
3266 * of the software configuration that drives hardware register programming.
3267 *
3268 * The function traverses the DC context and extracts values from:
3269 * - Stream configurations (timing, format, DSC settings)
3270 * - Plane states (surface format, rotation, scaling, cursor)
3271 * - Pipe contexts (resource allocation, blending, viewport)
3272 * - Clock manager (display clocks, DPP clocks, pixel clocks)
3273 * - Resource context (DET buffer allocation, ODM configuration)
3274 *
3275 * This is essential for underflow debugging as it captures the exact software
3276 * state that determines how registers are programmed, allowing analysis of
3277 * whether underflow is caused by incorrect register programming or timing issues.
3278 *
3279 * Return: true if state was successfully captured, false on error
