[RC4] Texture tests fail on OpenCL

[pjaaskel]

These (according to the test log) worked in RC3. Fail on Intel OpenCL CPU and the iGPU (OpenCL).

Yep, fails with RC3 too now (although in the RC3 test log it has marked passed). So, must be something's changed in my system since testing RC3. Investigating...

Yep. I had built my PoCL on Monday with the conformance on since I was tweaking CTS and forgot. In the conformance mode all texture types are not supported (as they are not yet conformant). Disabling the CTS mode fixed this problem.

.... than explains the PoCL failure but not the iGPU failure. For iGPU, the problem is the CHIP_USE_INTEL_USM setting. I'll create a workaround in cmake/UnitTests.cmake

[pjaaskel]

So, it gets enabled by default and it has the texture part not supported since the USM allocations do not support textures?

[franz]

No, it's disabled by default, so this is not a regression.

[pjaaskel]

...so it works with the default CMake options and you just had it explicitly enabled in your tests? OK.
