From: Ilia Mirkin Date: Sat, 8 Feb 2014 20:22:46 +0000 (-0500) Subject: nouveau/video: make sure that firmware is present when checking caps X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=40dd777b3307301e6580c5757c322a2ec99b5b37;p=mesa.git nouveau/video: make sure that firmware is present when checking caps Apparently some players are ill-prepared for us claiming that a decoder exists only to have creating it fail, and express this poor preparation with crashes (e.g. flash). Check that firmware is there to increase the chances of there being a high correlation between reported capabilities and ability to create a decoder.
