Subject: [PATCH] drm/vc4: crtc: Don't call into BO Handling on Async
|
|
Page-Flips on BCM2711
|
|
|
|
The BCM2711 doesn't have a v3d GPU so we don't want to call into its BO
|
|
management code. Let's create an asynchronous page-flip handler for the
|
|
BCM2711 that just calls into the common code.
