From: Erik Faye-Lund Date: Wed, 7 Nov 2018 15:00:59 +0000 (+0100) Subject: mesa/main: fix validation of transform-feedback queries X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=f09d94fbd113f6fd0e9583b6c21826281c39ea97;p=mesa.git mesa/main: fix validation of transform-feedback queries ctx->Extensions.EXT_transform_feedback is set based on the driver- capabilities, not based on the context type. We need to check against _mesa_has_EXT_transform_feedback(ctx) instead to figure out if the extension is really supported. We also need to check for OES_geometry_shader. This turns usage of GL_TRANSFORM_FEEDBACK_PRIMITIVES_WRITTEN into an error on ES 2, as well as usage of GL_PRIMITIVES_GENERATED on ES 3, both as required by the spec.
