gopcie PCIExpress library

Golang package gopcie implements data transfer to/from a PCIExpress hardware device on a Linux-based system. Data can be transferred via:

1. PCIExpress Direct Memory Access (DMA) transfers (requires kernel-space device driver) or
2. PCIExpress Base Address Register (BAR) accesses.

The BAR resource file identification is based on Andre Richter's easy-pci-mmap.

Utilities

• pcie_bar_read: Command-line utility to read data from PCIExpress Base Address Register
• pcie_bar_write: Command-line utility to write data to PCIExpress Base Address Register
• pcie_dma_read: Command-line utility to read data from PCIExpress device via Direct Memory Access transfer
• pcie_dma_write: Command-line utility to write data to PCIExpress device via Direct Memory Access transfer
