SYNOPSIS

void intel_psr_flush(struct drm_device * dev, unsigned frontbuffer_bits, enum fb_op_origin origin);

ARGUMENTS

dev

DRM device

frontbuffer_bits

frontbuffer plane tracking bits

origin

which operation caused the flush

DESCRIPTION

Since the hardware frontbuffer tracking has gaps we need to integrate with the software frontbuffer tracking. This function gets called every time frontbuffer rendering has completed and flushed out to memory. PSR can be enabled again if no other frontbuffer relevant to PSR is dirty.

Dirty frontbuffers relevant to PSR are tracked in busy_frontbuffer_bits.
