- void intel_edp_drrs_flush(struct drm_device * dev, unsigned frontbuffer_bits);
- DRM device
- frontbuffer plane tracking bits
This function gets called every time rendering on the given planes has completed or flip on a crtc is completed. So DRRS should be upclocked (LOW_RR -> HIGH_RR). And also Idleness detection should be started again, if no other planes are dirty.
Dirty frontbuffers relevant to DRRS are tracked in busy_frontbuffer_bits.
