Subject: [PATCH 190/454] drm/vc4: Don't wait for vblank on fkms cursor
|
|
updates.
|
|
|
|
We don't use the same async update path between fkms and normal kms,
|
|
and the normal kms workaround ended up making us wait. This became a
|
|
larger problem in rpi-4.14.y, as the USB HID update rate throttling
|
|
got (accidentally?) dropped.
