           Summary: [BXT] gem_shrink family subtests are failing
           Product: DRI

dmesg log with drm.debug=0xe

The following tests are failing on BXT, attached dmesg log for two tests, all
failures have similar output and dmesg, apparently running out of memory.

igt at gem_shrink@execbuf1-oom
igt at gem_shrink@execbufn
igt at gem_shrink@execbufn-userptr
igt at gem_shrink@get-pages-userptr
igt at gem_shrink@mmap-cpu-oom
igt at gem_shrink@mmap-gtt-oom
igt at gem_shrink@pread
igt at gem_shrink@pwrite-userptr


Steps to reproduce
=========================================
1. Download and Install IGT suite.
2. go to intel-gpu-tools/tests/ folder
3. execute test ./gem_shrink --run-subtest execbuf1-oom
4. execute test ./gem_shrink --run-subtest execbufn
5. execute test ./gem_shrink --run-subtest execbufn-userptr
6. execute test ./gem_shrink --run-subtest get-pages-userptr
7. execute test ./gem_shrink --run-subtest mmap-cpu-oom
8. execute test ./gem_shrink --run-subtest mmap-gtt-oom
9. execute test ./gem_shrink --run-subtest pread
10. execute test ./gem_shrink --run-subtest pwrite-userptr

Expected output
=========================================
Tests should be marked as pass


Actual output
==========================================

Tests are marked as fail  showing the following debug info ( more in dmesg)
