Why not just use Oprofile (oprofile.sf.net) or standard "readprofile" tool for this? I didn't know about that, but after a quick look I'd say Oprofile is doing performance profiling (which could be done using Qemu as well), not test coverage analysis. Also, the kernel in question needs to be p

[Qemu-devel] Idea: Qemu as test coverage tool for kernels

2006-01-28 Thread Blue Swirl
Hi, Qemu's system emulators could be modified to output information about the code areas which have been executed by the virtual CPU. The output could then be used in standard test coverage tools. The benefit would be the ability to get kernel-level coverage data. Are there any other tools f
