A 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.
