SYNOPSIS

void intel_edp_drrs_flush(struct drm_device * dev, unsigned frontbuffer_bits);

ARGUMENTS

dev

DRM device

frontbuffer_bits

frontbuffer plane tracking bits

DESCRIPTION

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.
