error: implicit declaration of function 'dma_zalloc_coherent' - error: implicit declaration of function 'dma_zalloc_coherent' Description Due to a kernel version difference, aocl install might fail with error: implicit declaration of function \'dma_zalloc_coherent\'. Resolution To workaround this problem, include following code in to linux64/driver/aclpci.c file in your Arria 10 BSP: static inline void *dma_zalloc_coherent(struct device *dev, size_t size, dma_addr_t *dma_handle, gfp_t flag) { void *ret = dma_alloc_coherent(dev, size, dma_handle, flag); if (ret) memset(ret, 0, size); return ret; } This problem is scheduled to be resolved in a future release of aocl.
