Iommus are very common on PC grade hardware, as well as premium smart phones. They just aren't that common on lower end phones and iot devices, but pcie is also fairly uncommon on those devices which makes your comment a bit confusing.
- AlotOfReading 3y agoThere's a lot of moderately powerful embedded Linux systems out there that either don't have an MMU equivalent or have one that the vendor BSP doesn't use by default. Too give one example, Xilinx doesn't set up the SMMU for AXI DMA devices on Zynq by default, iirc.
- codedokode 3y agoAs I understand, Zync is a FPGA, it is not used in consumer devices like laptops and smartphones so nothing bad happens even if there is a vulnerability.
- AlotOfReading 3y agoMost of the Zynq line include hard ARM A and/or R processors. Either way, just because something isn't in consumer electronics doesn't man vulnerabilities aren't important. Imagine a vulnerability in the control systems for your car or the planes you use.
