OSMC 2021 | Monitoring Open Source Hardware
0 likes88 views
The document discusses the monitoring of open source hardware, emphasizing the importance of transparency and accessibility in both software and firmware. It highlights various hardware types, open source implementations, and the transition of hardware management towards a software-like approach, labeled 'devhardops.' Additionally, it presents examples, such as OpenBMC, and suggests incorporating monitoring tools for enhancing hardware oversight.
