[Beignet] "utest_run -c runtime_use_host_ptr_buffer" failed to release test userptr object! [Append]

[Guo, Yejun]

It is a message from libdrm, what’s your exact version of libdrm and linux kernel?

I did not see this message at my Ubuntu14.04 64bit system with libdrm 2.4.58 (built from source) and linux kernel 3.19 (download from kernel.org)

My simple demo now has the same hint, Failed to release test userptr object! (9) i915 kernel driver may not be sane! , but it works correct last night.

I have used the Patch and run "echo 0 > /sys/module/i915/parameters/enable_cmd_parser".

主题: "utest_run -c runtime_use_host_ptr_buffer" failed to release test userptr object!

Hello,

1. When I run "./utest_run -c runtime_use_host_ptr_buffer", I get this message:

... ...
device_opencl_c_version "OpenCL C 1.2 beignet 1.1 (git-83f8739)"
Failed to release test userptr object! (9) i915 kernel driver may not be sane!
21 image formats are supported
... ...
runtime_use_host_ptr_buffer()    [SUCCESS]
Failed to release test userptr object! (9) i915 kernel driver may not be sane!

summary:
----------
  total: 681
  run: 1
  pass: 1
  fail: 0
  pass rate: 1.000000

2. When I run "cmake ../", maybe everything is OK, because I get this message:

running cd "/home/gss/files/beignet/utests" && mkdir generated -p  2>&1

3. I have written a simple demo using CL_MEM_USE_HOST_PTR, and it gets right result.

Problem: What's wrong with my Beignet?
