Overall there was diverse<br> crowd comprised of people from different companies/institutes. Some were<br> experienced in kernel and related areas, want to learn more and contribute.<br> Also, there were few students who were genuinely interested in the topic.<br><br> I later realized python meetup happening in parallel, thanks to that as well.<br><br><br> * First session was: "Submitting first patch upstream" by Jeetendra. It was<br> a nice interactive session with an example of how to send your first patch.<br><br> Started with version control system and benefits concentrating on git.<br> Jeetendra demonstrated use of "<a href="http://checkpatch.pl" rel="noreferrer" target="_blank" data-mce-href="http://checkpatch.pl">checkpatch.pl</a>", "<a href="http://get_maintainer.pl" rel="noreferrer" target="_blank" data-mce-href="http://get_maintainer.pl">get_maintainer.pl</a>" with some 'git' concepts<br> like create new branch for every new work and commit individual changes to new patch in<br> that branch.<br><br> He created a patch and compiled kernel after fixing a 'trivial style issue'.<br> He used 'git format-patch' to create patch from local commit and sent patch<br> using 'git-sent-mail' to staging mailing list.<br> Some discussion about git trees like staging, stable, linus and distro etc.<br> He also pointed to kernel documentation for all the steps. Attendees asked some doubts.<br><br> Siddhesh added with some benefits of git version control and more tips.<br><br> * Next we had 10 minutes meetup/Networking till next session starts. Also, small<br> refreshment (Thanks to Red Hat )<br><br> * After that I presented session on "Overview of Linux Memory Management"<br> I tried to explain, why we we need 'virtual memory' and how linux supports<br> it with the help of 'paging'. Idea was to start with basics. Also explained some<br> of the internals with MMU, TLB & page tables. Memory allocation using kmalloc & vmalloc.<br> Also, gave a small overview of MM concepts out of scope pf this session.<br> Attendees asked good questions...<br> - One question I got 'algo of buddy allocator'<br> - Zone vs Node relation. how zone manage pages?<br> - TLB flush for PTE update? entire TLB flush or just one entry<br> - kmalloc/vmalloc discussion<br> - What is high memory?<br> - Someone asked about OOM killer and its decision criteria?<br><br> Jeetendra asked me to can we do code walk through of any small part in coming meetups<br> and I noted.<br><br> * Siddhesh, 'Amit Kucheria' and me(Pankaj) requested attendees to join mailing list. Everyone<br> agreed to do regular meetup on last weekend of every month. Amit asked people to come<br> up with the ideas on topic of interests. As anyone can be interested in new topics as well.<br> So, different topics can be learning opportunity for everyone.<br><br> - 'Nitin Bansal' agreed to present session on 'crash' debugging with example.<br> - 'Jeetendra will give "session on ext filesystem in general"<br> - Amit asked me(Pankaj), can we include pending 'Networking session with QEMU/KVM' which I noted.<br> As initially we are planning to have two sessions on every meetup, we will have to see<br> if we can plan this for future meetups.<br><br> This is all the talk we had in the meetup. I really enjoyed attending it and enthusiasm of attendees<br> was awesome. I hope we will have more meetups in future and sessions to learn and share knowledge.<br><br> Thank you Guys!<br><br> Feel free to add if I missed any thing.<br><br> -----------------<br><br> Some of the my topics of interests are for future meet-ups on which i want to talk are:<br><br> * "Code walk through of any one topic of MM". Also I am interested to discuss about kVM MM internals.<br> * "Code walk through of any one topic of RT Kernel" or in general.<br> * "Overview of some of the kernel synchronization techniques or code overview of atleast one :-)"<br><br> Please share your thoughts or interested topics as well.<br><br> Best regards,<br> Pankaj<br><br><br> _______________________________________________<br> Kernel-meetup mailing list<br><a href="mailto:Kernel-meetup@lists.reserved-bit.com" target="_blank" data-mce-href="mailto:Kernel-meetup@lists.reserved-bit.com">Kernel-meetup@lists.reserved-bit.com</a><br><a href="http://lists.reserved-bit.com/listinfo.cgi/kernel-meetup-reserved-bit.com" rel="noreferrer" target="_blank" data-mce-href="http://lists.reserved-bit.com/listinfo.cgi/kernel-meetup-reserved-bit.com">http://lists.reserved-bit.com/listinfo.cgi/kernel-meetup-reserved-bit.com</a><br></blockquote></div><br></div></div></div><br>_______________________________________________<br>Kernel-meetup mailing list<br>Kernel-meetup@lists.reserved-bit.com<br>http://lists.reserved-bit.com/listinfo.cgi/kernel-meetup-reserved-bit.com<br></blockquote><div><br></div></div></body></html>
