Test on latest mesa master branch, It fails on all i965 platforms.
Following new cases fail on SNB/IVB/HSW/BYT.
spec_ARB_copy_image_arb_copy_image-formats_--samples=2
spec_ARB_copy_image_arb_copy_image-formats_--samples=4
spec_ARB_copy_image_arb_copy_image-formats_--samples=8

It also fails on 10.3 branch.

I'm aware of the failure.  However, this is not a failure of the ARB_copy_image implementation.  On the contrary, this is due to a loss of precision in the implementation of glGetTexImage.

Is this still a problem?  If so... is it included in the other work Igalia is doing?

This test can't possibly be actually running on ILK.  It requires multisample and sample_shading neither of which are advertised on ILK.  I also just verified that this skips on ILK with latest master.

output(10.4)

Test on latest mesa master andd 10.4 branch, it still fails.

Ok, I'm sorry, I got confused by a number of things in the report.  First, the initial report says ILK, but the test can't even run on ILK.  Please confirm what plaform you are running the test on.

Second, the arb_copy_image-formats test gets run with no arguments, with --samples=2, with --samples=4, and with --samples=8.  In the test, you say it fails with --samples=2, --samples=4, and --samples=8.  However, the output files you provide are clearly from running the test with no arguments.  Please clerify exactly how you are running the test.

Run on ILK

Attachment is from "bin/arb_copy_image-formats -fbo -auto" as comment 0. 

Test with arguments: --samples=2,  --samples=4, and  --samples=8, they are skip. The result is correct.  
[root@x-pk5 piglit]# bin/arb_copy_image-formats --samples=8 -auto -fbo
Test requires GL_ARB_texture_multisample
PIGLIT: {"result": "skip" }
[root@x-pk5 piglit]# bin/arb_copy_image-formats --samples=8 -auto -fbo
Test requires GL_ARB_texture_multisample
PIGLIT: {"result": "skip" }
[root@x-pk5 piglit]# bin/arb_copy_image-formats --samples=4 -auto -fbo
Test requires GL_ARB_texture_multisample
PIGLIT: {"result": "skip" }
[root@x-pk5 piglit]# bin/arb_copy_image-formats --samples=2 -auto -fbo
Test requires GL_ARB_texture_multisample
PIGLIT: {"result": "skip" }

Thanks for clerifying.  A bunch of those should be fixed after the Igalia format conversion patches land which should be mid-January.  Let's see how it looks then.

Tested in HSW with today's master (commit b9c2fa15e31c4904d4a2526b79ef3f70596c1074)

The "arb_copy_image-formats" test passes.

It's pass.(In reply to Antia Puentes from comment #10)

Test it on HSW and ILK.
It works well on HSW, but fails on ILK.

Confirming on ILK with Mesa master.

The specific test being run here is this command line "bin/arb_copy_image-formats -auto -fbo".
