Subject: Re: [PATCH 0/6] make ctx mgr global
Date: Thu, 18 Aug 2016 10:15:58 +0200 [thread overview]

NAK to the whole approach.
If we want to share dependencies in the form of fences between devices
and especially processes we must use android fences and the sync file
framework.
Sharing numbers in the form of the IDR is a security nightmare we
already ran into with the GEM flink design.
Regards,
Christian.
