Hi Nanley,

If you run the piglit test: arb_texture_view-rendering-format, and grep
for failures on HSW:

PIGLIT: {"subtest": {"clear GL_RGB10_A2 as GL_R32F" : "fail"}}
PIGLIT: {"subtest": {"clear GL_RGB10_A2 as GL_RG16F" : "fail"}}
PIGLIT: {"subtest": {"clear GL_RGB10_A2 as GL_RG16I" : "fail"}}
PIGLIT: {"subtest": {"clear GL_RGB10_A2 as GL_RG16_SNORM" : "fail"}}
PIGLIT: {"subtest": {"clear GL_RGB10_A2 as GL_RGBA8I" : "fail"}}
PIGLIT: {"subtest": {"clear GL_RGB10_A2 as GL_RGBA8_SNORM" : "fail"}} 

I remember seeing similar errors on Ivy too. They must be irrelevant to
the ETC support but as this test passes on BDW where the extension is
enabled, I didn't enable it on Gen 7 for the moment. I think I had
discussed about these failures with Kenneth before I disabled them, but
I didn't investigated them further after that.

Do you think I should enable it back?

Thanks,
Eleni
