HPC_UTILS is a utility for manipulating the hardware performance counters in RISC-V architecture compliant platforms.
hpc_utils is based on libhpc_utils.
To build hpc_utils and libhpc_utils, simply run make.
Currently libhpc_utils supports only SiFive's FU540-C000 U54.
For running on Freedom-U-SDK link libhpc_utils (libhpc_utils.a)
statically (with gcc argument -static) otherwise segfault occurs.
With hpc_utils you can program the counters and measure
the events' occurrences during execution of
a program. From more information run ./hpc_utils -h.
For information on how to use libhpc_utils,
check the csr_manipulation_test.c sample code in ./hpc_utils_lib/tests/src
and the hpc_utils.h header file in ./hpc_utils_lib/include/.
