Hi, I am using UML virtualization with cloonix. I have a kernel module to test with gcov. So I need to do coverage in linux kernel with uml. I read some information on gcov with uml on your website, but you only talk about gcov in user space. Can i do coverage on a module kernel with uml ? Currently, I build a custom uml linux with configure that you can find here: https://docs.google.com/document/pub?id=1yqr4XlDNyou0mRTtjhoQhWjhSZI6Mi8UY9w1ruYIYWY the kernel version that I use is 3.0.9. The problem is, when i try to mount debugfs wirth: mount -t debugfs none /sys/kernel/debug, gcov debugfs is not mounted. In a normal way, this command must mount a folder gcov in /sys/kernel/debug. Someone have a solution for me ? My apologize for my English Thanks in advance, Arthur Lambert. |
