What does it take to support high-performance ADCs and DACs in the kernel? To get the most out of these devices, we need to make some significant overhauls to PWM and SPI subsystems, including adding pivotal new features such as SPI offload and PWM waveform to the upstream Linux kernel. This has ultimately led to adding support for dozens of ADC/DAC devices in the IIO subsystem and expanded the capabilities of those already there, allowing them to operate up to millions of samples per second without jitter. We'll give a high-level overview of how this project came about, the target hardware configurations, test equipment used, and methods to make it all happen, along with the challenges we overcame in the process. A "lessons learned" approach to this review and some possibilities for future work will round out the talk.
