[PATCH i-g-t v4 0/1] tests/intel/xe_exec_capture: Add xe_exec_capture test

[Dong, Zhanjun]

Dear Peter,

Thanks for testing the patch.
Yes, the failure is due to I add "Capture_source" field check since v3.
It actually find out a bug in my kmd code. Solution/Jira is working in 
progress.

If you want to skip this failure to continue the run, you can comment 
out this line like:
diff --git a/tests/intel/xe_exec_capture.c b/tests/intel/xe_exec_capture.c
