Philip Yang 36776e9917 kfdtest: avoid BigBufStressTest run on NUMA node 0
Because dma32 zone is on node 0, use all system memory on node 0 will
cause TTM eviction to free dma32 zone for other devices which only
work with 32bit physical address. The TTM eviction and restore may take
too long and cause queue timeout.

Running on other NUMA nodes, the NUMA default memory policy is
MPOL_PREFERRED, means TTM will get pages from local node first, and then
get remaining pages from other nodes. Check /proc/buddyinfo can confirm
this.

Reset NUMA bind to all after the test.

1. Note on building kfdtest

To build this kfdtest application, the following libraries should be already
installed on the building machine:
libdrm libdrm_amdgpu libhsakmt

If libhsakmt is not installed, but the headers and libraries are present
locally, you can specify its directory by
export LIBHSAKMT_PATH=/*your local libhsakmt folder*/
With that, the headers and libraries are searched under
LIBHSAKMT_PATH/include and LIBHSAKMT_PATH/lib respectively.


2. How to run kfdtest

Just run "./run_kfdtest.sh" under the building output folder. You may need
to specify library path through:
export LD_LIBRARY_PATH=/*your library path containing libhsakmt*/

Note: you can use "run_kfdtest.sh -h" to see more options.
