[Intel-gfx] Question regarding gem_alive test case in intel-gpu-tools-1.7 suite

[Meng, David]

Hi Team:
Greetings.

I am new to send a question to this email list.  I am working on GPU driver for VMware ESXi kernel running on BDW system. The driver is based on the OTC graphics driver which is released with Linux 3.19.3.

When I tested the driver using the test case gem_alive from intel-gpu-tools -1.7, the result is always fail. The kernel driver complains that the object handle is 0.  By checking the gem_alive.c code, it is found the test case dose not create any gem object but tries to  use  DRM_IOCTL_I915_GEM_SW_FINISH ioctl call to finish a object.  As a result, it returns –ENOENT error.

I wonder is there any special kernel driver feature to be tested by this case?  Or we expect it is always fail?

Thank you for any answer.

Regards,

David
