* Implement the hipOccupancyMaxPotentialBlockSize function * Replaced hipGetDeviceProperties() call by ihipGetDeviceProperties() in ihipOccupancyMaxPotentialBlockSize() * Add test for hipOccupancyMaxPotentialBlockSize in Module API * Added extern declaration for ihipGetDeviceProperties() to be accessed inside ihipOccupancyMaxPotentialBlockSize() * fixed hipOccupancyMaxPotentialBlockSize test build issue * Fix hipOccupancyMaxPotentialBlockSize dtest * Add BUILD_CMD in hipOccupancyMaxPotentialBlockSize dtest * Revert "Add BUILD_CMD in hipOccupancyMaxPotentialBlockSize dtest" This reverts commit 0480ff56f1441fc515d2c26ce33783e303423938. * Disable hipOccupancyMaxPotentialBlockSize dtest on NVCC * move extern declaration of ihipGetDeviceProperties to hip_module.cpp * Update the limiation of 32 wavefronts per CU and 800/512 SGPRs for VI/pre-VI chips to calculate the occupancy
