Subject: [PATCH V2] venus: fix multiple encoder crash
Date: Fri, 1 May 2020 11:58:00 +0530 [thread overview]
Message-ID: <1588314480-22409-1-git-send-email-mansur@codeaurora.org> (raw)
Currently we are considering the instances which are available
in core->inst list for load calculation in min_loaded_core()
function, but this is incorrect because by the time we call
decide_core() for second instance, the third instance not
filled yet codec_freq_data pointer.
Solve this by considering the instances whose session has started.
Signed-off-by: Mansur Alisha Shaik <mansur@codeaurora.org>
