7.4.1. MMD Layer Hardware Interaction Library Class mmd_device
This class has the following responsibilities:
- Acquire the FPGA AI Suite IP, the stream controller (S2M only) and the mSGDMA
- Register interrupt callback for the FPGA AI Suite IP
- Provide read/write CSR and DDR functionality to the FPGA AI Suite runtime
- Linux device discovery.
The class attempts discovery of the following UIO devices, each from the /sys/class/uio/ui*/ namespace.
coredla0 |
This represents the FPGA AI Suite IP CSR registers. |
stream_controller0 |
If present (S2M only), this represents the Stream Controller CSR registers. |
layout_transform0 |
If present (S2M only), this represents the Layout Transform CSR registers. Note that this device is not directly controlled from the runtime. |
The class also attempts to discover the following mSGDMA-USERIO devices.
/dev/msgdma_coredla0 |
This represents the mSGDMA used to transfer weights, instructions, microcode, and, during M2M operation, image data. |
/dev/msgdma_stream0 |
This represents the mSGDMA used to transfer images to the Layout Transform during the S2M mode of operation. |
