Poking eudyptula for status updates
Hello all, I've been waiting for a week now since I submitted task 5 to Eudyptula. I understand reviewing submissions takes time, specially the tasks that are reviewed manually and there is a queue. Plus, it helps make the challege replicate the experience of contributing to an open project. Waiting is fine. What I am wondering is if my task fell through the cracks. Not sure if there is a method to poke eudyptula for a status update. To confirm the submissions is in the queue. Is there an equivalent of politely asking a project maintainer about review when a decent amount of time has passed since submission? I know that if you resubmit you get pushed to the tail of the queue. Sorry if this has been asked or explained before, I have searched and couldn't find anything about the matter. Sorry for yet another Eudyptula related email in the list. Thanks, Luis ___ Kernelnewbies mailing list Kernelnewbies@kernelnewbies.org http://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies

Just to be clear, a mail responding to the task submission/confirmatin or a new one?

In case of this you can expect at least a notification (as it was with lost submissions in June).

You can try email little directly, if you concerned about position in the queue, but i've never tried. ___ Kernelnewbies mailing list Kernelnewbies@kernelnewbies.org http://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies

Re: About guiding hello world module submission
Hey Mayur, I am not exactly sure what you need. 1) If you need to know how to send patches per mail, check Greg's talk here (https://www.youtube.com/watch?v=LLBrBBImJt4) 2) If you need help setting up an email inbox for receiving student's patches, just go for one of your preferred freemail hoster (they probably all suck) 3) If you need an inbox with Webmailer/POP3/IMAP, I can set you up one on one of my domains. Just drop me a line and I'm gonna set it up for you. 4) If you need something completely else, ask more precisely! ;) Cheers, Lukas On Thu, 25 Jun 2015 at 14:44 Mayur Patil linuxcra...@gmail.com wrote: Yes Lukas right I want to do the same.

Afterwards you can get the Emails together and discuss their results. I suppose you do not intend to send dummy-patches to a real maintainer for getting his feedback?

Could please suggest me the place where I can guide the students to send the device driver? Not sure what do you want to achieve with this. To show students how to contribute to the Linux kernel you can find small coding style issues in the drivers/staging/ directory and send them to Greg KH. We are doing this every year and its a lot of fun.

Re: How to handle float-point operations
Hello Mudongliang, On Tue, Jun 23, 2015 at 9:01 AM, 慕冬亮 mudonglianga...@gmail.com wrote: I know there are rarely float-point operations! What's the exception? In the linux kernel, how does it handle the float-point operations in the userland? Most of the userspace programs do not use FP instructions. So by default floating point engine is turned off during a context switch. When a process executes floating point instruction, an undefined exception is generated. Exception handler enables the floating point engine and jump back to the same instruction which caused the exception so that it will get re executed with FP engine on. thanks, Arun - mudongliang ___ Kernelnewbies mailing list Kernelnewbies@kernelnewbies.org http://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies ___ Kernelnewbies mailing list Kernelnewbies@kernelnewbies.org http://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
