From: Kenneth Graunke Date: Tue, 6 May 2014 23:04:40 +0000 (-0700) Subject: i965: Enable GL_ARB_texture_view on Broadwell. X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=ecfc418b68d3368df0f72116adad153c19d8c6d8;p=mesa.git i965: Enable GL_ARB_texture_view on Broadwell. This is a port of commit c9c08867ed07ceb10b67ffac5f0a33812710a5e8. A tiny bit of extra work was necessary to not break stencil texturing.
