Nicholas Kazlauskas 0eb71d3d5b drm/amd/display: Only revalidate bandwidth on medium and fast updates ... commit 6eb3cf2e06d22b2b08e6b0ab48cb9c05a8e1a107 upstream. [Why] Changes that are fast don't require updating DLG parameters making this call unnecessary. Considering this is an expensive call it should not be done on every flip. DML touches clocks, p-state support, DLG params and a few other DC internal flags and these aren't expected during fast. A hang has been reported with this change when called on every flip which suggests that modifying these fields is not recommended behavior on fast updates. [How] Guard the validation to only happen if update type isn't FAST.
