Single board computer with very fast GPIO (>=40 MHz)

Hi,

I'm looking for a single-board computer with a very specific feature:
-A very fast 32 Bit parallel input (40 MHz at least) that can run continuously over hours without any drops, with internal or external clock (alternatively LVDS input). No protocol, ADCs are connected to that
-A way to transmit or store that data, so either USB3 interface or 2.5G Ethernet is needed.
-Should run Linux

What I do not want:
Some restricted proprietary SDK, closed source drivers etc. Preferable all drivers/devicetree are upstream in the kernel.

Any idea?

Best regards
Stefan

Single-board computer is not, I bought PCIe X4 fpga board for this purposes.

Spartan-6 (or 7) board:
 I/O -> capture to small internal buffer -> softcore DVI interface (read XAPP495) -> Any fast HDMI capture board

How do you program it? I remember working with an Altera FPGA at university some time ago. The Altera software for it was the worst, it was proprietary, extremely complicated GUI, needed some outdated libraries to work (not documented), was painfully slow (sometimes 30 minutes or to get the binary on a recent machine), sometimes it failed after that time, nobody could tell you why, no clear error messages. Nothing I ever want to use again.

I would like to give it a try, when:
a) There are simple open-source command-line tools to create the binaries for the FPGA
b) The functionality is documented with fully working examples you can modify and use in your code

I had a quick look I couldn't find anything. I also had a look for PCIe to parallel cards, but those I could find were all priced at least 4 digits and with proprietary SDKs. A <100€ FPGA PCI-e card would probably a good option, but not with horrible software.

Best regards
Stefan
