David Francis 30b1f23f7a kfdtest: Add coherency tests for Aqua Vanjaram
Aqua Vanjaram is intended to have fine-grained coherency
from anywhere to anywhere else using read-acquire and
write-release primitives.

Add a test that writes to memory covered by five
different cache lines, then write-releases, while
another thread read-acquires, then reads those
five locations in memory.

There are nine variations of the test to cover
CPU-GPU, same-GPU and across-GPU, vector instructions and
scalar instructions, and data local to the
acquirer or receiver.

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.
