Hello, sorry I just set up irc and do not know how use it properly. 2011-04-14T08:38:37 I still do not have the co-mentor, my thesis supervisor sent out some e-mails but no reply yet :/ 2011-04-14T08:40:11 hi, patben. what is this project about . do you have a link of your proposal 2011-04-14T08:42:44 It is a resource reservation framework and I am to port it on RTEMS. 2011-04-14T08:43:02 link: http://www.google-melange.com/gsoc/proposal/review/google/gsoc2011/petben/1 2011-04-14T08:43:25 if it is port to RTEMS ,what can brought to RTEMS? 2011-04-14T08:46:35 It depends how RTEMS people assess it, it will include an EDF scheduler working with the new pluggable infrastructure at least. 2011-04-14T08:48:40 It is my master thesis, so I do it anyway, if there is at least a particular interest of RTEMS side, I may include it in GSoC. 2011-04-14T08:49:27 That's it :) 2011-04-14T08:50:33 the frescor is a framework for embedded application? and if you port it to RTEMS mean that user can write application for RTEMS using frescor? do i understand right? 2011-04-14T08:53:36 Exactly, the user will start as if it was a normal application but with a possiblility for tasks to be independent of each other via CPU time reservation for instance. 2011-04-14T08:55:44 There are also some other resources capable of being reserved such as network bandwidth and one can also make up other ones.

Is it possible to do Ethernet Layer communications with RTEMS, rather than TCP/IP layer? 2011-04-14T12:40:48 I've used WinPcap on the PC side. 2011-04-14T12:40:55 bswimley: I'm not very familiar with the networking stack, so I dont' know how easy it is to access the phy/mac layers... 2011-04-14T12:40:59 But certainly it is possible 2011-04-14T12:41:15 I just don't know how well the interface supports it. 2011-04-14T12:41:27 DrJoel might have a better idea 2011-04-14T12:42:41 I'm not that familiar with the networking stack either. I'm banking on Dr. Joel as well! 2011-04-14T12:42:59 tbh, the networking experts primarily respond via email 2011-04-14T12:43:41 Good point. I'll post to the mailing list as well. 2011-04-14T12:44:04 bswimley: You'll probably get a more precise answer by asking about specific networking layers 2011-04-14T12:44:21 OK. Yes, it's at the Ethernet layer. 2011-04-14T12:44:29 OK. I think that should be pretty well available 2011-04-14T12:44:35 mac/phy is usually done by hw... 2011-04-14T12:45:25 I would think it is possible. Like you, however, I'm unsure of the interface into the networking stack. 2011-04-14T12:45:38 what are you trying to do? 2011-04-14T12:45:45 bswimley: post to the mailing list. ;-D There is a tap point in the network stack where you can see raw packets. I don't know about sending them 2011-04-14T12:46:03 Thanks Dr. Joel! I will do that. 2011-04-14T12:46:51 We have an application that communicates at the Ethernet layer on a custom interface controlled by an FPGA. 2011-04-14T12:47:15 I want to expose a bit of that protocol to the other interface, which is managed by RTEMS. 2011-04-14T12:47:56 Not really a bridge, but I just want to hook a couple of devices that speak our custom protocol up to this other interface. 2011-04-14T12:48:02 brb 2011-04-14T12:49:07 ahh. and you do this with pcap.. i wonder if anyone ever tried to port pcap to rtems 2011-04-14T12:49:52 Yep - WinPcap if I'm on a windows box. Yes, I was actually wondering about a pcap port. 2011-04-14T12:50:11 I don't recall seeing it, but that would be pretty cool 2011-04-14T12:50:25 you might want to ask that as part ofyour email 2011-04-14T12:50:52 Yes - I was going to look into it and I will ask as well. Don't know what the pcap licensing is, however. 2011-04-14T12:51:27 i think it is bsd = good 2011-04-14T12:51:30 depends on which bsd though 2011-04-14T12:52:21 On the site now. Still looking for licensing. 2011-04-14T12:52:44 check their source distribution 2011-04-14T12:55:44 Hmm, license is: BSD. No particular flavor. 2011-04-14T12:56:02 as long as there is no advert. clause it is OK 2011-04-14T12:56:11 that is the only issue with bsd-like licenses. 2011-04-14T12:56:24 *IANAL* ;) 2011-04-14T12:56:41 I'm married to one :) 2011-04-14T12:57:00 I think this might be the clause in question: 2011-04-14T12:57:05 2.

Yes, you should have a relatively clear plan of action so that we know what you are going to do 2011-04-15T11:00:19 hexene: suggest that you also elaborate what you can submit to RTEMS project, such as new cache management implementations, test suite, so on 2011-04-15T11:01:18 hexene: one of the criticisms for your proposal is that you just list a bunch of cpus/archs... should be more specific and probably scale back a little. it is hard to evaluate the work you expect can be done. 2011-04-15T11:01:55 ok 2011-04-15T11:04:03 gedare: by specific, do you mean I should list the cache functionality implemented in each model/arch? 2011-04-15T11:04:30 hexene: as much as you can, or suggest why the archs/cpus you propose will be feasible for you to implement and test 2011-04-15T11:05:12 hexene: I know for a fact some of them will not be...and you should have some clues about the scope of the work you propose 2011-04-15T11:05:44 ok 2011-04-15T11:07:14 hexene: I don't remember if you did, but you should include some discussion about the test cases you tried to make, and what you discovered. 2011-04-15T11:08:44 ok, I've figured out how to test the data cache routines 2011-04-15T11:09:20 that's great, definitely talk about that and highlight how you can contribute a cache test suite 2011-04-15T11:09:50 and post a comment after you update your proposal to highlight the things you changed/added. 2011-04-15T11:11:26 gedare: I'm not sure the current implementation of invalidate_entire_data() is correct though 2011-04-15T11:11:45 given that once you invalidate the cache, you lose the return address for the function too 2011-04-15T11:11:46 hexene: identify that, and say that its something that can be refined and worked on 2011-04-15T11:12:03 only if the RA is cached, if it is in register or flushed first it should be OK 2011-04-15T11:12:13 some of this is arch specific, which is fine 2011-04-15T11:13:01 yes, the RA would have to flushed explicitly (on i386 atleast) 2011-04-15T11:14:10 it is good to put some of these details on your proposal. it shows you are thinking about the problems. 2011-04-15T11:14:51 ok got it
