Greetings, In part two of the final TCG Continuous Benchmarking report, the same procedures introduced in part one are used for inspecting the performance of QEMU system mode emulation. The only difference is instead of emulating the same OS for all targets, different images where selected from the Qemu-devel thread below and the official QEMU documentation.
https://www.mail-archive.com/qemu-devel@nongnu.org/msg604682.html For each of the five targets used in this report (arm, hppa, m68k, mipsel, and sh4), the source of the used emulation instructions is mentioned. This is followed by a snippet for fetching the required files and starting the system emulation. The results of running the time command are then displayed for measuring the boot-up time until the login screen is reached where the emulation is stopped. The top 25 executed QEMU functions are also measured using the topN_system.py script introduced in part one of the report.
