Oh, and telling people not to read resources and decide for themselves is questionable behavior.
Doing it without being up front about who you are just makes it rude.
- seba_dos1 6y agoI will tell people to not read resources that state blatantly incorrect information as facts and don't even bother to cite where they got that information from, especially when the actual facts can be easily checked by anyone since all the information about how those firmwares work have been publicly available for many months now and the phone is already in hands of many users who can check it themselves on actual devices. It's not a matter of opinion or interpretation where my affiliation could actually make a difference, that post is just demonstrably false and not worth anyone's time (and if anything, the fact that I work for Purism on the Librem 5 makes my position stronger, because I know how these phones work).
- atat7024 6y agoA bibliography isn't going to find the Librem an IOMMU.
- seba_dos1 6y ago...and what benefit would exactly an IOMMU bring to a device with no PCIe and which's critical peripherals do not use DMA at all? IOMMU is vital for devices where e.g. modem is tightly integrated on the SoC and uses the same RAM as your OS. This is not such device. Even if iMX8MQ had an IOMMU, the modem would still be connected to the SoC via USB2.0 and the WiFi card via SDIO, where you don't need an IOMMU to ensure boundaries and where having one wouldn't change anything at all.
