Patches for supporting SGI Octanes are floating around since ages. The latest version is against v4.10. I've talked to Ralf Baechle (MIPS kernel maintainer) and he is willing to take patches from me... so I have to provide them... and this what this project is for:-)
Trimatik MC is an older heating control from Viessmann. It has no supported digital interface for remote access, but I found at least two ways to get access to sensor data like various temperatures and state of relay contacts. One way is to use the so called remote control the other use the clock timer. This project will use the latter way, because the hardware adaption is much easier and and all four timer channels could be controlled as well. Remote access will be done via an ESP32, which emulates the clock timer and gets/pushes data via WIFI.
Current prototype is able is able to monitor traffic between the original clock timer and the heating control.
With the approach of kernel 5.6 SGI Octanes are supported with builtin IO components. What's missing for a graphics workstation is a driver for the graphics card. There is already a not upstreamed framebuffer driver for Impact graphic cards. Since there will be no new framebuffer driver accepted upstream, the goal of this project is to convert the existing frame buffer driver to a DRM driver and make it ready to be sent upstream.
Some of my old workstations (Sun3, Apollo DN3x00/4x00) use ECL signals for their monochrome monitor. Since these monitors are already dead or dying I was looking for a conversion to something more modern. As I couldn't find anything I found the ULX3S boards, which already have everything for driving a HDMI monitor. So goal of this project is to use the FPGA board for converting the video signal.
My Canon Powershot camera has integrated WiFi, but I haven't found a tool, which supports it. Gphoto2 project has support for PTP (Picture Transfer Protocol) via LAN and it looks like this is usable for accessing the camera.
