Motativation

This was apart of my "Understanding of OS theoretical concepts" and emulator series. I enjoy my time with this project, if you're interested in AMD virtualization then read chapter 15 of the amd manual.

Warning

This project is yet to be finished. It's still a W.I.P so there maybe errors, so feel free to report any if possible. Syscall Hooks aren't finished yet.

TODO List:

  • Finish setting up IPI to be executed on execute
  • Finish up the SYSCALL Hooking
  • Add fast page hooking

Credit - Special Thanks:

Thanks to these OGs, for the spark of inspiration/support and just being good friends/acquaintances overall on my continuous effort on this project and for helping me understand certain concepts within HyperVisor development Journey. =)

  • xeroxz - Helping explain concepts around HV and allowing me to use his code semantics for his amazing Hypervisor project
  • Daax - His big brain coming in clutch like always. He's given me a great layout on the semantics of a AMD HyperVisor and his approach on it, sharing resources left and right. Even answered my most trivial questions. Daax never misses
  • horsie - sharing some resource
  • tandasat - Amazing resource
  • Irql0 - explaining certain Windows kernel driver, OS concepts and getting me out of tough assembly problems
  • iPower - sharing an approach to hooking System Calls and helping fix my VMCB issues
  • Matthias - For providing information that lead me on to fixing a VMEXIT_INVALID bug i came across and for going out of his way to even debug my HyperVisor to point logic issues and errors. Thank you so much
