Syntax of "paddr" is dbgfs's own. I don't think handling it in paddr is a right thing to do.

This has really bothered me for a long time. I don't send patches just for the sake of sending patches. I integrate DAMON patches into my kernel, and one obvious problem is that I don't use paddr at all. But my config had to select DAMON_PADDR so that my DAMON codes would compile and work. I wanted DAMON code to be as simple and clean as possible, which is why I sent the patch for three times. I quite agree with what you said, it is necessary to conduct sufficient test and verification, which I have not done enough. However, I will conduct further test later. I don't think we should not modify the previous test case just because it will affect it.

Thank you for the clarification. I know you really want to improve DAMON and made great progress already. I really appreciate that. I can also understand your frustration. Of course, it's optimal to compile only what we need. However, this code is for the community, not for specific users. And, I still unsure how much pain is incurred by the compilation of one additional source file for you, and others in the community. And, sometimes we can compile some of unnecessary code and thus make the binary a tiny bit bigger to make the code simple. If it seems the benefit of dropping DAMON_PADDR dependency is clearly bigger than increased complexity of dbgfs and the change doesn't break any other things to me, I will happily give you my 'Reviewed-by:'. Else, I'm sorry but I wouldn't. Also, please note that I have a plan[1] to make more reliable DAMON user interface based on sysfs, and it would not have such unnecessary dependencies.

I'd like to suggest you to do https://github.com/awslabs/damon-tests/tree/master/corr, or at least https://github.com/awslabs/damo/blob/next/tests/run.sh in addition to those. Also, please ensure you are caring not only DAMON_VADDR && DEBUG_FS, but also DAMON_PADDR && DEBUG_FS. This also reveals another downside of this patch. This requires DAMON tests to cover the one more configuration case. And actually it's currently affecting you. I hope the benefit of next patch clearly outweighs the effort for that. Of course, it would be even greter if you can clearly guarantee the patch will not break other things with the code or comments. Thanks, SJ > > > > > I don't find answers to the requests here.
