Hi,
Is there anyway I can test the front buffer tracking?
On latest drm-intel-nightly, I am observing that when ubuntu bootsup
after few secs (like ~15Secs)
there no call from intel_fb_obj_invalidate() to invalidate the drrs.
But system is healthy and FBs are keep changing. But no notification
to DRRS for FB status change.
I have verified this by observing the busy_frontbuffer_bits from
/sys/kernel/debug/dri/0/i915_drrs_status. This bit is not changing at
all.
Hence DRRS is stuck at DRRS_LOW_RR itself.
Is it known valid issue? Or am I doing something wrong.!?
