From: Timothy Arceri Date: Fri, 7 Apr 2017 01:40:40 +0000 (+1000) Subject: mesa: don't lock hashtables that are not shared across contexts X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=918cec8cbeeac58b8d9092d6fc4aacb8490eb50c;p=mesa.git mesa: don't lock hashtables that are not shared across contexts From Chapter 5 'Shared Objects and Multiple Contexts' of the OpenGL 4.5 spec: "Objects which contain references to other objects include framebuffer, program pipeline, query, transform feedback, and vertex array objects. Such objects are called container objects and are not shared" For we leave locking in place for framebuffer objects because the EXT fbo extension allowed sharing. We could maybe just replace the hash with an ordinary hash table but for now this should remove most of the unnecessary locking.
