<pre>Setup:
* BSW N3050
* Ubuntu 18.04
* Gfx stack built from Git
* GfxBench v4 / v5 (reproduced with latter, but v4 should work the same)
Use-case:
* bin/testfw_app --gfx glfw --gl_api desktop_core --width 1920 --height 1080
--fullscreen 1 --test_id gl_4
Actual outcome:
* Abort with following message:
testfw_app: src/intel/common/gen_urb_config.c:152: gen_get_urb_config:
Assertion `total_needs <= urb_chunks' failed.
This regressed between following Mesa commits:
41c8f99137: 2018-11-12 18:28:04: util: Fix warning in u_cpu_detect on non-x86
e13dd70581: 2018-11-14 14:41:58: i965: avoid 'unused variable' warnings
In case it matters:
* i965 has always misrendered Carchase benchmark on BSW, see <a class="bz_bug_link
bz_status_NEW "
title="NEW - [BSW] CarChase benchmark misrenders"
href="show_bug.cgi?id=101406">bug 101406</a>
* GfxBench Vulkan Aztec Ruins and SynMark DeferredAA & TexMem128 started
to GPU hang around 6th of November, but for now this seems more of
a drm-tip kernel than Mesa issue</pre>
