From: Maarten Lankhorst Date: Mon, 9 Sep 2013 11:02:08 +0000 (+0200) Subject: st/dri: do not create a new context for msaa copy X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=b217d48364f368f541e53006af5dd56f664be24d;p=mesa.git st/dri: do not create a new context for msaa copy Commit b77316ad7594f st/dri: always copy new DRI front and back buffers to corresponding MSAA buffers introduced creating a pipe_context for every call to validate, which is not required because the callers have a context anyway. Only exception is egl_g3d_create_pbuffer_from_client_buffer, can someone test if it still works with NULL passed as context for validate? From examining the code I believe it does, but I didn't thoroughly test it.
