@gzobraJn @iPowerPower Thank you, glad you enjoyed it! 😁

@Gbps111 @iPowerPower Eye opening blog post. Thank you.👏👏 Now, i have to read the other posts. 👀

I just published the long-awaited Part 2 to my PCIe blog post series - "All About Memory: MMIO, DMA, TLPs, and more!" This post also includes a companion experiment where I dive into what pcileech looks like over a PCIe protocol analyzer. Please enjoy! ctf.re/kernel/pcie/tu…

@aall86 Thank you, Andrea! 😁

This is an excellent writeup from my friend Gbps. Must read! Congratz @Gbps111 !

@UlfFrisk What kind of interface design are you using for the transfer? Some kind of DMA ring buffer or XDMA?

The LeechDMA driver itself is a well-behaved Thunderbolt/PCIe driver between controller PC and ZDMA device for any kind of fast TB/PCIe data transfers. The 2nd FPGA of the ZDMA device can be programmed by the user, in the example above it's programmed as a PCILeech device.

Created a driver! ZDMA device performance with LeechDMA driver is 🔥🔥🔥 github.com/ufrisk/pcileec…

My second HackerOne bounty through Valve :) Tried out using #frida to write the exploit, worked out very well! Enjoy! ctf.re//source-engine…

@SpecterDev Have you tried doing try{}catch{} on the whole driver?

I don't write drivers they crash too much

@gmhzxy @PetrBenes Could you shoot me more information? I'd be happy to help debug.

@PetrBenes But It runs failed in WIN10 1803

gbhv - another awesome, simple, clean and nicely documented x64 hypervisor! github.com/Gbps/gbhv
