--- Comment #1 from lu hua <huax.lu at intel.com> ---
I reproduce it on igt commit: g5fb26d1.
outout:
IGT-Version: 1.9-g5fb26d1 (x86_64) (Linux:
3.19.0-rc3_drm-intel-nightly_0056b6_20150109+ x86_64)
Test assertion failure function gem_set_domain, file ioctl_wrappers.c:366:
Failed assertion: drmIoctl((fd), ((((1U) << (((0+8)+8)+14)) | ((('d')) <<
(0+8)) | (((0x40 + 0x1f)) << 0) | ((((sizeof(struct drm_i915_gem_set_domain))))
<< ((0+8)+8)))), (&set_domain)) == 0
Last errno: 2, No such file or directory
Subtest write-cpu-read-wc: FAIL (0.025s)


Test on the latest igt, It works well and fixed by commit
3214a27b5ba7cd621b091f1d0702e069a750c054.
