Subject: [Qemu-devel] [PATCH v5 00/10] Measure Tiny Code Generation Quality
Date: Wed, 14 Aug 2019 23:18:47 -0300 [thread overview]
Message-ID: <20190815021857.19526-1-vandersonmr2@gmail.com> (raw)
This patch is part of Google Summer of Code (GSoC) 2019.
More about the project can be found in:
https://wiki.qemu.org/Internships/ProjectIdeas/TCGCodeQuality
The goal of this patch is to add infrastructure to collect
execution and JIT statistics during the emulation with accel/TCG.
The statistics are stored in TBStatistic structures (TBStats)
with each TB having its respective TBStats.
We added -d tb_stats and HMP tb_stats commands to allow the control
of this statistics collection. And info tb, tbs, and coverset commands
were also added to allow dumping and exploring all this information
while emulating.
Collecting these statistics and information is useful to understand
qemu performance and to help to add the support for traces to QEMU.
v5:
- full replacement of CONFIG_PROFILER
- several fixes
- adds "info cfg"
- adds TB's targets to dump
vandersonmr (10):
accel: introducing TBStatistics structure
accel: collecting TB execution count
accel: collecting JIT statistics
accel: replacing part of CONFIG_PROFILER with TBStats
accel: adding TB_JIT_TIME and full replacing CONFIG_PROFILER
log: adding -d tb_stats to control tbstats
monitor: adding tb_stats hmp command
Adding info [tbs|tb|coverset] commands to HMP. These commands allow
the exploration of TBs generated by the TCG. Understand which one
hotter, with more guest/host instructions... and examine their
guest, host and IR code.
monitor: adding new info cfg command
linux-user: dumping hot TBs at the end of the execution
