| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | [WHY] On DCN314, using full screen application with enabled scaling like 150%, 175%, with overlay cursor, causes a second cursor to appear when changing planes. Dpp cache is used to track the HW cursor enable. Since power gate is disabled for hubp & dpp in DCN314, dpp_reset() zero'ed the dpp struct, while the dpp hardware was not power gated. So, when plane is changed in a full screen app, and the overlay cursor is enabled, the cache is cleared, so the cache does not represent the actual cursor state.

| * drm/amd/display: Include EQU Prefetch Bandwidth For Bandwidth CalculationsAustin Zheng2025-06-242-23/+35
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | [Why] Pixel data bandwidth required in mode programming (MP) ends up being higher than what was calculated in mode support (MS) even though the prefetch bandwidths calculated in MP are lower than the MS ones. MP used a different equ prefetch schedule than MS which lead a slight difference in parameters. This resulted in the pixel data bandwidth in MP to be higher than MS. [How] Rename the RequiredPrefetchBWOTO term so it can be applied generically. Update the value with the EQU bandwidth if the EQU schedule is used. Get the max prefetch bandwidth that MS calculated and use it as part of the calculations for required bandwidth.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | [Why] Common modes are added to eDP for compatibility in clone mode, but not all panels support them. Non-native modes were disabled in the past but this caused problems because compositors didn't use scaling for non native modes. Now non-native modes on eDP will enable the scaler by default. [How] Check the connector type. If the connector is eDP avoid adding common modes.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | [Why] Common resolutions are added to supported modes to enable compatibility scenarios that compositors may use to do things like clone displays. There is no guarantee however that the panel will natively support these modes. [How] If the compositor hasn't enabled scaling but a non-native resolution has been picked for an eDP panel turn the scaler on anyway. This will ensure compatibility.
