WIP

@ChuckMcManis @SteveBellovin I would rather say, they're completing the work Sun started with Solaris. systemd isn't a clone of Windows' services, systemd is a clone of Solaris' svcs.

@BrucePerens_K6BP The actual demodulation code is the same, since it's running on the processor, but e.g. the spectrum calculation takes place in the FPGA.
A lot of interaction with the programmable logic is hidden in the kernel driver which is controlled via ioctls.
The forked KiwiSDR code can be found here https://github.com/RaspSDR/server/tree/master, but the source code of the kernel module unfortunately not.

@BrucePerens_K6BP The Web-888 uses a totally different FPGA design and Linux kernel interface compared to the KiwiSDR.

@BrucePerens_K6BP That's because the KiwiSDR uses a standalone FPGA that communicates with the SBC over SPI, while the Web-888 uses a Zynq-7000 SoX and shared memory for interaction between PL and PS parts.

@BrucePerens_K6BP Unfortunately not open. They neither published the FPGA block design nor the source code for their kernel module. You don't even get a schematic.
