QEMU: Emulating Your Way to Success
summary
QEMU performs full system and user-mode emulation to run foreign kernels and binaries, translate CPU code, and fake buses and devices for testing; examples include emulating a different x86 on a developer laptop to exercise Linux x86 entry code and building virtualised hardware to validate a SoC boot stack. Integrations shown: openQA for CI-driven install and UI tests, a GDB server and QMP socket for control and inspection, device models taking ~7–8 days per IP core, and tradeoffs around accuracy and upstream maintenance.
