Expand Post This content is a preview of a link. support.xilinx.comI have had to make few patches to compile using Yocto for kernel 5.15 for ARM (attached in xilinx_dma.diff) I have run the qdma_run_test_pf.sh together with datafile_16bit_pattern.bin with one queue only and it works for MM H2C and C2H and with ST H2C. It does not with C2H ST. In particular, register QDMA_C2H_BUF_SZ[0:15] is a 16-bit field. Can we use the full 16-bit, i.e. the maximum buffer size of 65536 bytes. However, in the Xilinx example device driver code, it has a maximum limit of 0x7000. dmaxfer.c: #define QDMA_ST_MAX_PKT_SIZE 0x7000. Therefore, is there a document that defines the above maximum value. QDMA supports three types of C2H stream modes: simple bypass, cache bypass, and cache internal. Currently, I am working on the cache bypass mode with prefetch to send data from the card to the host. The problem is that QDMA does not transfer data to the host after receiving a specific number of requests. It seems that the problem originates ...
