Qdma xilinx.

QDMA driver fails to initialize (eqdma_indirect_reg_clear) I am new to FPGA development, and I am trying to use QDMA in my design. I have designed a simple module to understand how QDMA works. The DMA interface of QDMA is configured as "AXI Memory Mapped", and other options are left default. When I insert the Xilinx's kernel module (qdma-pf.ko ... 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. sankalp@96 (Customer) asked a question. Important: QDMA dmactl (Linux Driver) -VCU1525 not working as expected (as per Xilinx Answer 70928) Setup Steps (as per document): - 1. make (all drivers compiled pf , vf, user and tools). 2. make install (drivers installed). 3. modprobe qdma (loaded driver in auto mode). 4.Hi @dsakjlras0 ,. As mentioned above, the QDMA platforms are replaced with the Host Memory Access feature found on some production platforms (See the latest UG1120, table 6 - the 2021.1 version should be released shortly).The HMA feature (formerly called Slave Bridge) is expected to have improved performance over the … This video from Xilinx walks through the process of creating a simple hardware design using IP Integrator (IPI).
