[Mesa-dev] [PATCH] i965: Gut the separate OpenGL ES extension enabling.

Kenneth Graunke kenneth at whitecape.org
Tue May 15 15:49:16 PDT 2012


We should just set the bits of functionality that we support; the
GL/ES1/ES2 flags in extensions.c will take care of advertising the
appropriate extensions for the current API.

This enables the GL_EXT_texture_compression_dxt1 extension on ES1/ES2
when libtxc_dxtn is installed or the force_s3tc driconf option is set.
The main extension code set this up properly, but the ES-specific code
failed to do so.

Otherwise, the extension strings reported by es1_info, es2_info, and
glxinfo all remain the same.

This patch manually disables the ARB_framebuffer_object bit on ES
to preserve the behavior of 1c0f5d8324c4db2720247989ddc4a45315b55a85.
