</span>This seems to cause regressions in the following Piglit tests for Gen9:<br>
<br>
piglit.spec.ext_texture_compression_s3tc.getteximage-targets cube_array s3tc<br>
piglit.spec.arb_texture_cube_map_array.fbo-generatemipmap-cubemap array s3tc_dxt1<br>
<br>
I think the spec for the extension is based on the GLES spec. Perhaps<br>
the intention was to add ASTC support for cube-map array textures<br>
whereas previously in GLES no compressed formats were supported for this<br>
target. However in regular GL presumably S3TC is supposed to be<br>
supported. As it stands this patch disables cube-map array textures for<br>
any formats other than ASTC whenever the ASTC extension is available, so<br>
it disables S3TC on Gen9.<br>
<br>
Maybe this section should be limited to GLES?<br>
