pcm VS openFPGALoader

I don't know how often it's a problem, but I work for a company doing software video encoding, and we always fill up all the dimm slots on servers to have as much bandwidth as possible, even if we have only really use maybe 1/4 of the RAM.

I'm not sure any of the standard Linux tools can show you memory bandwidth usage easily (maybe perf), I know we use Intel PCM (https://github.com/intel/pcm) and AMDuProfPCM (https://www.amd.com/en/developer/uprof.html)

The Intel PCM suite does what you seem to be describing w/o a kernel module, and it uses nicely abstracted MSR accesses so that its portable to any OS.

Measure with pcm-pci / pcm-iio https://github.com/intel/pcm

For my purpose, I want 1. Enough, but not excessive lanes for GPU. For upcoming PCIe5 enabled GPUs (which may not even happen just yet), we don't know if they can saturate 16x. Would be nice if someone could run https://github.com/intel/pcm pcm-iio and measure. If it turns out that PCIe5 enabled GPUs aren't using more than 8x bandwidth, then X670E 8/8/4 mode makes sense, if you can saturate the remaining lanes with something else.

Another way to flash the devices in Linux is to use https://github.com/trabucayre/openFPGALoader which supports a variety of cables and devices. It also supports the Xilinx Virtual Cable protocol, which allows you to use Xilinx tools like ChipScope with almost any cable.

Even though I saw multiple proposed solutions around the web, I could not get the Gowin cable to be detected under Ubuntu Linux as well, so neither the programmer nor GAO could work. I tried opensource openFPGALoader as an alternative to the programmer (but not GAO of course..), but got some issues as well (not with cable, but with certain bitstreams causing the programming to hang). So the easiest solution for me to stick with Windows version.

i could/should eventually open a ticket on the openFPGAloader indeed

Most Linux users seem to prefer openFPGALoader, but if you need GAO and the other suggestions don't work you might have to use a Windows VM, thankfully Gowin IDE supports (supported?) Windows XP/7 if you want a lightweight guest.

You might be able to use a tool like openFPGALoader to load a bitstream onto your board from macOS.

Try openFPGALoader. It works fine in Windows 10 and Linux for me. https://github.com/trabucayre/openFPGALoader

There's the open source openFPGALoader with explicit support for macOS if i remember correctly, I'm not sure if it supports all the features but it should be a good starting point.

u/PCB4lyfe all you need are just the drivers for the USB blaster. To load the bitstream you can use openFPGALoader https://github.com/trabucayre/openFPGALoader

OP, if that doesn't work, and you feel comfortable installing openFPGALoader (https://github.com/trabucayre/openFPGALoader), I can send you the GPIO demo bitstream to put on your board.
