i was able to do this with old libnetworking 2015-04-06T11:58:03 i haven't used it, i'm not sure, you may need to ask on the devel mailing list. this new port has mostly been used by sebastian 2015-04-06T11:59:33 also, so you are aware, it seems the lwIP port that is available relies on some code in the drivers that we cannot combine with RTEMS. so any effort with lwIP may require new re-write/port of lwIP with "clean" drivers. 2015-04-06T11:59:34 gedare: okay thanks 2015-04-06T12:00:06 this would definitely increase the time needed, and if you're accepted you and your mentor can figure out how to adjust schedule for it. 2015-04-06T12:04:03 hi, gedare! 2015-04-06T12:04:05 the issue is the EULA needed to download the Starterware from TI 2015-04-06T12:04:06 hi andrei_ 2015-04-06T12:04:09 gedare: hmmm yes ... 2015-04-06T12:04:22 ragunath: not something to worry about now though 2015-04-06T12:05:29 gedare: :) 2015-04-06T12:08:33 *** yangqiao has quit IRC (Remote host closed the connection) 2015-04-06T12:09:52 regarding the comments on my proposal 2015-04-06T12:10:49 my understanding is that a monotonic clock 2015-04-06T12:10:56 is a clock which starts at a given time 2015-04-06T12:10:58 an doesn't reset 2015-04-06T12:11:02 and* 2015-04-06T12:12:00 I tried reading about 2015-04-06T12:12:06 condition variables and monotonic clocks 2015-04-06T12:12:23 but the only thing I understood so far is that 2015-04-06T12:12:35 the benefit of having a monotonic clock is that, if you have a timed wait 2015-04-06T12:12:38 and system time changes 2015-04-06T12:12:45 you don t lock for a long time 2015-04-06T12:13:03 you may like to ask ppisa for more info what he means then 2015-04-06T12:14:30 I believe that posix cond var have support for that 2015-04-06T12:14:35 so I would just need to interface it 2015-04-06T12:15:26 sounds right to me 2015-04-06T12:15:44 but you may want to check current support in rtems/posix. 2015-04-06T12:16:07 I traced https://github.com/RTEMS/rtems/blob/master/cpukit/posix/src/condtimedwait.c 2015-04-06T12:16:13 back to https://github.com/RTEMS/rtems/blob/master/cpukit/posix/src/condwaitsupp.c 2015-04-06T12:16:25 *** yangqiao has joined #rtems 2015-04-06T12:17:07 I haven't checked yet, but I expect rtems kernel not to be linked with glibc 2015-04-06T12:17:11 because it's large 2015-04-06T12:17:18 we use newlib 2015-04-06T12:17:29 there is some of the posix impl there 2015-04-06T12:17:32 and some in rtems 2015-04-06T12:18:48 I found https://github.com/epicsdeb/rtems-gcc-newlib 2015-04-06T12:19:00 *** Hesham has quit IRC (Ping timeout: 265 seconds) 2015-04-06T12:19:00 I suppose I can look in it 2015-04-06T12:22:48 *** yangqiao has quit IRC (Ping timeout: 250 seconds) 2015-04-06T12:23:05 google newlib 2015-04-06T12:23:18 the official version is in sourceware.org 2015-04-06T12:24:22 ah, ok, so the upstream one is fine 2015-04-06T12:26:04 For the second aspect Cyrille Artho about what I mean with refactoring 2015-04-06T12:26:31 what I mean is "adapt POSIX implementation to fit with score implementation" but that's obviously not the level of detail required 2015-04-06T12:27:39 I looked at barrier and coremsg but 2015-04-06T12:28:08 could you point me to a score implementation that relies on the posix implementation 2015-04-06T12:29:17 I looked at mutex and semaphore too, but I believe mutex and semaphore rely on classic implementation, is that correct? 2015-04-06T12:29:18 thanks ! 2015-04-06T12:32:40 hmm 2015-04-06T12:35:52 not off the top of my head. you may either look around a bit more, or use your imagination and see what you come up with. ;) 2015-04-06T12:36:48 but really, you want to have just some idea what the implementation looks like inside the score 2015-04-06T12:37:04 mostly, it will probably look a bit like the posix implementation, but with score objects instead, and a callout to deal with locking 2015-04-06T12:37:28 it really is a "refactor" from posix -> score. you're putting the condvar implementation in score, so that it can be shared across posix and classic APIs 2015-04-06T12:38:01 then you tailor the posix and classic to make use of the score correctly. for posix this means it offers the same (or improved) functionality as before, and for classic you get to figure out what the condition variables should offer to RTEMS users. 2015-04-06T12:39:22 think of the Classic and POSIX APIs are "wrappers" for the score. 2015-04-06T12:39:42 wow 2015-04-06T12:39:51 I pretty much thought of exactly the opposite 2015-04-06T12:40:04 "you call" the score 2015-04-06T12:40:08 which figures what to call 2015-04-06T12:40:38 score should be as oblivious as possible to its caller 2015-04-06T12:41:12 we necessarily will a poke a hole because of the need to acquire a mutex in the caller's layer 2015-04-06T12:41:53 it'll help a lot to go through the code with what you said in mind 2015-04-06T12:41:54 thanks 2015-04-06T12:44:28 great 2015-04-06T13:01:13 *** Davidbrcz has joined #rtems 2015-04-06T13:19:35 *** gwty has joined #rtems 2015-04-06T13:59:26 *** ita has quit IRC (Ping timeout: 244 seconds) 2015-04-06T14:00:13 *** ita has joined #rtems 2015-04-06T14:04:12 hi all 2015-04-06T14:07:33 *** gedare has quit IRC (Ping timeout: 248 seconds) 2015-04-06T14:08:51 *** rak[1] has joined #rtems 2015-04-06T15:01:32 *** yangqiao has joined #rtems 2015-04-06T15:08:55 *** andrei_ has quit IRC (Ping timeout: 246 seconds) 2015-04-06T15:08:55 *** yangqiao has quit IRC (Quit: Leaving) 2015-04-06T15:10:47 *** Davidbrcz has quit IRC (Ping timeout: 252 seconds) 2015-04-06T15:12:05 *** Hesham has joined #rtems 2015-04-06T15:15:15 *** gedare has joined #rtems 2015-04-06T15:15:15 *** ChanServ sets mode: +o gedare 2015-04-06T15:30:00 *** yangqiao has joined #rtems 2015-04-06T15:30:18 hi gedare 2015-04-06T15:36:01 hi yangqiao 2015-04-06T15:36:14 I've implement the mailbox and framebuffer for rpi bsp.
