I am working on building a custom Android emulator (similar to BlueStacks) and I’ve decided to use QEMU as the underlying virtualization engine.
However, after reviewing the official documentation, I find it more focused on usage rather than internal architecture. My goal is to deeply understand how QEMU works internally so I can modify it—specifically the interface/GUI layer and how it handles input/output for the guest OS—to make the emulator "feature-complete" for gaming.
I would like to know:
Source Code Structure: Where should I start looking in the QEMU source tree to understand the display and UI initialization (e.g., GTK, SDL, or VirtIO-GPU implementations)?
Internal Architecture: Are there any recommended resources (books, whitepapers, or specific developer wikis) that explain the interaction between the TCG (Tiny Code Generator) and the hardware abstraction layer?
Modification Workflow: For someone looking to add custom features to the emulator's shell/interface, what is the standard approach for extending QEMU's frontend?
Any guidance on which specific modules handle the graphical output and user interaction would be greatly appreciated.
