Dasharo v0.9.0 Brings Open-Source Firmware to AMD AM5

A First for AMD's AM5 Platform

Firmware developer 3mdeb has released Dasharo v0.9.0, described as the first open-source firmware to reach AMD's AM5 desktop platform, targeting the MSI B850-P WiFi motherboard 1. The release combines Coreboot, the long-running open-source boot firmware project, with AMD's openSIL silicon initialization framework, allowing Zen-based systems to boot without relying entirely on proprietary vendor firmware 1. For a platform historically locked into closed UEFI implementations from OEMs, this marks a notable milestone for hardware transparency and user control over boot-level code.

The achievement lands amid a broader, and often contentious, moment for the term "open source" across the technology industry, where the label is being applied — and contested — in contexts far beyond firmware.

Open Source's Expanding, Contested Meaning

In artificial intelligence, the phrase has become a flashpoint. AMD chief executive Lisa Su publicly defended open-source AI at the company's Advanced AI conference, doing so shortly after a security breach involving Hugging Face that was reportedly caused by OpenAI's own agents — an episode that fed skepticism about how safely open models can be deployed 2. Meanwhile, analysts at Bank of America pointed to a wave of new open-source model releases, including China's Kimi K3, as evidence supporting a bullish outlook on memory demand and on Micron Technology specifically, arguing that proliferating open models drive greater compute and memory consumption 3.

Not everyone views China's open releases so favorably. One commentary frames Chinese open-source AI as a geopolitical "Trojan horse," warning it fosters dependency, enables censorship, and hands Beijing leverage over Western users 4. A separate business-focused critique argues the comparison to open-source software is misleading altogether, contending that China's "open-weight" AI models impress developers technically but represent a poor business model, fundamentally different from the collaborative economics that made open-source software sustainable 6. Adding a policy dimension, reporting notes that new Trump administration restrictions on private AI model releases are pushing more attention — and resources — toward open-source alternatives as companies and researchers seek paths around the tightened rules 7.

Open Source Beyond AI

The term also surfaces in more everyday consumer contexts. DisplayPort's status as an open-source standard is cited as one reason graphics card makers favor it over licensing-heavy HDMI, limiting how many HDMI ports appear on video cards 5. And hobbyists are repurposing old tablets as Android Auto head units using Headunit Revived, an open-source application that revives otherwise obsolete hardware for automotive use 8.

Taken together, the range of stories illustrates how differently "open source" functions depending on domain — from a genuine firmware breakthrough on AM5 to a heavily disputed label in the AI arms race, alongside its quieter, more settled role in consumer hardware and software standards.
