From 3bcce5c0d931bf623adc5974200e4d7636b10bef Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Thu, 20 Dec 2012 11:17:17 +0100 Subject: [PATCH] ALSA: hda - Check CORB overflow Add an overflow check of CORB in HD-audio controller and codec drivers so that flood of sequential writes would work properly. In the controller side, add a check of CORB read-pointer to make returning -EAGAIN when it's full. Meanwhile in the codec side, when -EAGAIN error is received, it retries the write after flushing the pending verbs (calling get_response() essentially does it).
