2025-12-08drm/amd/display: Reset pipe mask at beginning of cursor offloadNicholas Kazlauskas
[Why] Double cursor when switching between hardware and software cursor when dragging an MPO window can occur with cursor offload enabled. The abort cursor update in the full programming path is responsible for this issue since it does not reset the pipe mask when attempting to submit an empty update. The firmware programs the payload as requested which may contain invalid or stale data for the previously enabled pipes, resulting in an offset or double cursor. [How] For performance we don't want to memset the entire payload structure due to its size, so just reset the pipe mask which will indicate the payload data is empty.

[How] We do the translation to destination space currently twice: once in the HWSS layer, and then again in the HUBP layer since we never store the translated result.
