Using TSE with PCIe in a Linux enviroment

Hi Terence,

thanks for the hint.

I adapted the a TSE reference design with logic + memory. So the Qsys-architecture is like

- PCIe Avalon MM

|

- TSE MAC (control port)

|

- Scatter Gatter DMA TX --- Avalon ST to TSE transmit

|

- Scatter Gatter DMA RX --- Avalon ST to TSE receive

|

- OnchipMem for descriptor memory

|

- Some PIO

The root port is a x86. I have access via the pci-structure to the PIO (some LEDs) and that doing well.

Do you know a possiblity to test the TSE only with some memory-settings via PCIe.

What information (device tree?) must a kernel know to access the TSE via the structure above?

We want to use it as a network device, so we can send a ping for example.

Thanks in advance,

Chris
