Also, users can be deceived by putting a sticker on the malicious device with the name on the prompt - the writing on the plastic agrees with the prompt, so the device must be legit. As we've found on mobile, when apps pop up prompts about permissions users are conditioned to agree.

The name is often not descriptive, eg 'CalDigit TS3' in our example, so users can't tell what rights are being asked for.

Second, the prompt says 'you attached a thing, do you want to allow it?'. First is that Macs have no prompt at all, so you just need to use a device on the whitelist and you're approved. We don't break that prompt, however there are some problems. Users can communicate with FPGA IP cores by writing only a few lines of code.Īuthor here. On the software side there are two main functions: data send and data receive. RIFFA supports Windows and Linux, Altera and Xilinx, with bindings for C/C++, Python, MATLAB and Java. The framework requires a PCIe enabled workstation and a FPGA on a board with a PCIe connector. > RIFFA (Reusable Integration Framework for FPGA Accelerators) is a simple framework for communicating data from a host CPU to a FPGA via a PCI Express bus. Different abstractions are provided to simplify the implementation of PCIE devices. It supports PCIE configuration headers, requests, memory read/write operations and MSI. It allows PCIE devices to be implemented as standard userland processes, answering actual PCIE requests coming from > virtual environment consisting of QEMU, LINUX and GHDL glued alltogether by a small TCP based protocol. If you later move beyond QEMU, these OSS projects may be of interest. It pains me to hear people complaining about the lack of Thunderbolt in AMD Ryzen Mobile laptops, and wishing for it in the next generation now that the spec is no longer Intel-exclusive in some way. The entire thing is made -even worse than USB-, which is an achievement. But of course the Linux driver has two or three hardcoded ones, including indexes into the EEPROMs on the way, that it recognizes and loads a hardcoded configuration for. You can describe a lot of different networks in it. Ah, and let's not forget that the absurdly complicated MPLS-like system with topology written in EEPROMs in every node that, as far as I can tell, you have to bitbang via the half-configured packet path (what the actual fuck?), well, it's very general. Thunderbolt is an MPLS-like packet switching network that can encapsulate PCIe TLPs over a PHY and MAC without a spec, chips without documentation, and software with barely any support. > Thunderbolt, uh, does not expose PCIe lanes directly. Not just in the sense of 'we're making an internal bus external before ensuring security', but just in what it actually is: Thunderbolt is a horrendous piece of garbage.
