Subject: Device Description for FPGA Components on x86 system
Date: Wed, 27 Mar 2019 18:17:18 +0100	[thread overview]
Message-ID: <1629227.alSmCsHHUc@pcbe13614> (raw)

Hello,

I'm looking for guidance

What I have:
* Intel x86_64 computer
* PCIe card with FPGA on it

What I want to achieve:
* load an FPGA bitstream on the card
* load a device-tree like description for the FPGA devices contained in the 
bitstream

This is achievable on ARM with DeviceTree, overlay-dt, fpga-mgr; but I'm 
puzzled about the x86_64 use-case. I'm not able to find recent and clear 
information.

Does anyone know if this is doable? Perhaps with ACPI SSDTs overlay? Or with 
the DT?

thanks
