[Qemu-devel] How to speed up the CPU logging?

2012-06-09 Thread Yue Chen
Hi, Guy, When I use *log cpu* or *log exec* in the system *-monitor stdio* mode, it's extremely slow(lose my mouse/keyboard control). I used a buffer instead of directly writing log to disk, but even slower. When I give a large memory (-m 4G) to VM, or set the process priority(chrt -f 99) of

Hi, Does anyone know, how to run(replay) the intermediate micro-ops directly? For example, I have traced some micro-op instructions, and want to see what happens with these instructions(after being translated into host code and then run). Probably with Graphic User Interface. Any approach to do
