[BSW] Mesa "total_needs <= urb_chunks" abort in GfxBench CarChase startup, when asserts are enabled
Submitted by Eero Tamminen

Link to original bug (#108787)
Description
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: 41c8f991: 2018-11-12 18:28:04: util: Fix warning in u_cpu_detect on non-x86 e13dd705: 2018-11-14 14:41:58: i965: avoid 'unused variable' warnings
In case it matters:
- i965 has always misrendered Carchase benchmark on BSW, see bug 101406
- 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
