Subject: [PATCH] drm/amd/display: Only revalidate bandwidth on medium and fast
|
||||||
|
updates
|
||||||
|
|
||||||
|
[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.
|
||||||
|
|
||||||
|
[How]
|
||||||
|
Guard the validation to only happen if update type isn't FAST.
|
||||||
