I'm using linux-0.2.img image(which is a light linux image) to debug kernel using Qemu.
where do you get that image? and why don't you make one by yourself?
I'm working on IO schedulers' optimization. As Qemu boots kernel, IO scheduler sends read requests to disk. Also by entering commands such as 'ls', it sends read requests. I'm looking for a way to send write requests.
"echo" command? "dd"?
Thus I thought that using a benchmark which sends both read and write requests, is suitable, but as linux-0.2.img is a very simple and light image, it is almost impossible to setup heavy benchmarks on it.
could you explain what do you mean by "heavy"?
So I want to use an ubuntu image instead. But I don't know where I should see kernel printks.
"see"? or "set"? I believe it's the latter, right? what do you want to see through printk, anyway? -- regards, Mulyadi Santosa Freelance Linux trainer and consultant blog: the-hydra.blogspot.com training: mulyaditraining.blogspot.com
