126.96.36.199.3.1. Meta Data Test
Meta data is the 8-byte private data that the host sends to the device in the H2D direction and the device sends to the host in the D2H direction.
- If we have meta data enabled in the bitstream, modify IFC_QDMA_META_DATA like below in common/mk/common.mk
__cflags += -DIFC_QDMA_META_DATA
__cflags += -DPERFQ_LOAD_DATA
- Continue with user library build and installation steps.
./perfq_app -p 128 -s 128 -d 1 -u -a 2 -b 0000:01:00.0 -v -c 1
Note: To verify the meta data functionality, every descriptor should have eof set to 1. Use the commands in such a way that every descriptor contains a single file. Use perfq_app with the -s parameter.
