U55N support?

[OhGodAPet]

I would love to see support for the C1100 (U55N) in this!

I tried to add support for au55n but I encountered some issues. Please see below.

Looking at the project structure, we need to add the following for au55n:

• add a folder under board_files/Xilinx (e.g., name it au55n and place the board files there). I copied the board files from /opt/xilinx/platforms/xilinx_u55n_gen3x4_xdma_1_202110_1/hw/hw.xsa (I decompressed the archive). The /opt/xilinx/platforms/xilinx_u55n_gen3x4_xdma_1_202110_1 folder is created by installing the deb packages from https://www.xilinx.com/products/accelerators/varium/c1100.html. Please see https://github.com/dloghin/open-nic-shell/tree/main/board_files/Xilinx/au55n
• add a folder under constr. I copied the files from au50 and adapted the pins based on the info in part0_pins.xml under board_files. Please see https://github.com/dloghin/open-nic-shell/tree/main/constr/au55n
• add a new file named cmac_usplus_0_au55n.tcl under src/cmac_subsystem/vivado_ip. I adapted this from au50. Please see https://github.com/dloghin/open-nic-shell/blob/main/src/cmac_subsystem/vivado_ip/cmac_usplus_0_au55n.tcl.

This last file is the source of my build error:
[ERROR] ... Value '4x25' is out of the range for parameter 'Line Rate(NUM_LANES)' for IP 'cmac_usplus_0' . Valid values are - 10x10
I also get these warnings:

Looking at the other boards, au55n is missing the preset.xml file (this should be under board_files/Xilinx/au55n/). Where to get this file from? I could not find it under /opt/xilinx/platforms/xilinx_u55n_gen3x4_xdma_1_202110_1/.

In summary, it would be great if the AMD-Xilinx team can add support for au55n (Varium C1100). Thank you.
