Re: [Qemu-devel] Re: Ideas wiki for GSoC 2010
IMO one of the biggest parts of infrastructure QEMU is missing for embedded stuff is a common (qdev) way of modeling DMA backchannels. Or devide to device channels or whatever you want to call it. Would be nice if someone could bring this to qemu. Cheers

But as far as 9P is concerned, do you need help there Anthony? If so, would you take over the mentoring? == Add more sophisticated encodings to VNC server == I could probably help out being a secondary mentor here, but Anthony would be a good fit as primary, no? I guess Kraxel could help out too. == Write a C QMP library based on QEMU JSON and QMP code == Suggested by Anthony, mentored by Anthony? :) Possible other candidates are Luiz and Kraxel I guess? I haven't really tracked QMP that much. == Add support for guest copy/paste == This should probably be folded into the above VNC server improvements. By itself it's just too little of a task. == Device state visualization == Jan, Kraxel? Maybe too small for a task? == Upstreaming some of the Android emulator bits == Jan, Anthony? If you read the suggestion and just think to yourself well yes, I think I could do it - then put your name in the wiki :). Alex

I haven't really tracked QMP that much. I didn't candidate as a mentor myself because Anthony has a better idea wrt to the public API. But I certainly can help with the implementation. I have more two or three QMP projects to suggest, btw. == Add support for guest copy/paste == This should probably be folded into the above VNC server improvements.

I think that whether a task is small or not also depends on the student, of course that we should not come up with a project that can be easily done in two weeks. On the other hand, 'not that difficult' tasks can be an excellent project for those really new to open source and serious development. You know, when you're a starter you spend quite a lot of time reading code and trying things out (and there's nothing wrong with that). So, for this kind of project the mentor only should take extra care to choose a student that is really going to learn a lot in the project.
