These are notes I've taken while rying to get srslte up and running. This is messy, sorry...

This brief tutorial will show you how to go about analyzing a raw binary firmware image in Ghidra.
I was recently interested in reversing some older Cisco IOS images. Those images come in the form of a single binary blob, without any sort of ELF, Mach-o, or PE header to describe the binary.
While I am using Cisco IOS Images in this example, the same process should apply to other Raw Binary Firmware Images.

Modern versions of Windows support GPU paravirtualization in Hyper-V with normal consumer graphics cards. This is used e.g. for graphics acceleration in Windows Sandbox, as well as WSLg. In some cases, it may be useful to create a normal VM with GPU acceleration using this feature, but this is not officially supported. People already figured out how to do it with Windows guests though, so why not do the same with Linux? It should be easy given that WSLg is open source and reasonably well documented, right?
Well... not quite. I managed to get it to run... but not well.
