Description Ian Romanick 2014-07-16 02:36:14 UTC 
On my IVB laptop with current Mesa master (9a723b970), I hit:

Test case 'ES3-CTS.gtf.GL3Tests.framebuffer_blit.framebuffer_blit_functionality_multisampled_to_singlesampled_blit'..
cts-runner: gen7_blorp.cpp:190: uint32_t gen7_blorp_emit_surface_state(brw_context*, const brw_blorp_params*, const brw_blorp_surface_info*, uint32_t, uint32_t, bool): Assertion `(fieldval & ~ (((1<<((13)-(0)+1))-1)<<(0))) == 0' failed.
Aborted (core dumped)

This is not a failure that I recall seeing before, so I think it is a recent change.  I have not had a chance to bisect yet.

Bisecting may not be that useful - that assertion just means you're programming a value for a field which is too large to fit in the number of bits the hardware uses to represent it.

It will probably be pretty easy to fix upon inspection.

Mark, I see that we're running this test in CI on HSW, BDW, and SKL. Why isn't it being run on IVB?
Comment 3 Mark Janes 2017-02-28 20:05:24 UTC 
This tests passes in CI on a nightly basis.
