Description Diego 2013-07-30 10:58:39 UTC 
glmark2-es2 crashes after running the jellyfish benchmark in a fsl-image-gui-sdk image for machine nitrogen6x. I think this issue is present on all Vivante GPU based boards.

How to reproduce:
- build a fsl-image-gui-sdk
- bitbake glmark2
- install libpng12 and glmark2 on the image
- run the test with "glmark2-es2 --fullscreen"
- get the crash after the jellyfish benchmark

Comment 1 Otavio Salvador 2013-07-30 12:04:36 UTC 
Diego,

is this always reproducible?

> is this always reproducible?

Yes, I can always reproduce it in Yocto on my Nitrogen6x, even on BSP 3.0.35-4.0.0.

By the way I don't have this crash on FSL Ubuntu BSP 3.0.35-1.1.0 and 3.0.35-4.0.0 installing the prebuilt glmark2.

Sorry. Just though about it: prebuilt glmark2 on FSL Ubuntu is a previous version, 2012.03.
IIRC glmark2 2012.03 has less subbenchmarks than 2012.08, so it's could just be a matter of missing the benchmark that crashes the driver.
Comment 4 B07273 2013-08-09 09:36:32 UTC 
Before this bug is fixed, please try this walkaround:
Modify shader file terrain-noise.frag:
@@ -29,7 +29,7 @@ vec4 taylorInvSqrt(vec4 r)

 float snoise(vec3 v)
{
-    const vec2 C = vec2(1.0 / 6.0, 1.0 / 3.0);
+    const vec3 C = vec3(1.0 / 6.0, 1.0 / 3.0, 1.0);
     const vec4 D = vec4(0.0, 0.5, 1.0, 2.0);

     // First corner

Hi,

this modifications avoids the crash, thank you for the workaround. Now waiting for a proper fix.

Diego
Comment 6 Otavio Salvador 2013-08-23 23:23:33 UTC 
An workaround is being for in 3.5.7-1.0.0-alpha.2 drivers but it does not fix the problem.
Comment 7 Otavio Salvador 2013-09-04 19:45:28 UTC 
Resolved in 3.5.7-1.0.0-alpha.2 GPU release.
