2019-03-05 Thread José Roberto de Souza
When PSR2 is active aka after the number of frames programmed in PSR2_CTL 'Frames Before SU Entry' hardware stops to generate CRC interruptions causing IGT tests to fail due timeout. This same behavior don't happen with PSR1, as soon as pipe CRC is enabled it blocks PSR1 activation so CRC calculat
