[REPORT] [GSoC - TCG Continuous Benchmarking] [#10] Measuring QEMU Performance in System Mode - Part Two

[Ahmed Karaman]

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.
