Re: [maemo-developers] problem with dspmp3sink (was: problem with gstreamer and dsppcm)
Hi, Also I noticed that gstreamer is not very reliable, at least when using it from mplayer. It can freeze or reboot the device sometimes. That's not something that should be expected from high level API. If I detect some reliable pattern in reproducing these bugs, I'll report it to bugzilla for sure. But right now just using mplayer and lots of seeking in video can cause these bugs reasonably fast. First I would recommend using just top to see whether mplayer is either: - Leaking memory - Otherwise using too much memory Either by itself or forcing gstreamer to do that. If that is the case, the bug is in the mplayer (or gstreamer (plugin)) and it needs to be fixed. For debugging the leaks, I would recommend using Valgrind on x86. - Eero PS. The applications in the device have been done so that they integrate into the the device memory management framework; if they have dynamic or large memory usage, before doing large allocs, they check whether system has enough memory for those, they react to system low memory notifications etc. If an application forces the kernel to the OOM (out of memory) situation, it will by default kill the application requesting memory. However, if mplayer is run as root, its killing is avoided (note most of the framework processes are run as normal user). Also, if you're using Desktop while mplayer triggers device OOM, it's Desktop using memory and kernel might kill it (which reboots the device). FYI: Only way to handle OOM correctly is to avoid triggering it, trying something fancy (in kernel) in that situation is AFAIK wraught with deadlocks. ___ maemo-developers mailing list maemo-developers@maemo.org https://maemo.org/mailman/listinfo/maemo-developers
Re: [maemo-users] Re: [maemo-developers] Future features for Maemo Desktop (Task Navigator, Home, Status bar)?
Hi, And lastly, the Task Navigator bar width should be configurable. There is no reason for its fattness as it is - it is just a waste of desktop realstate, IMHO. Actually, there is a reason -- so that you could hit the icons with your thumb. It would be difficult if the bar was slimmer, or the icons smaller. I think making Task Navigator thinner would also require new theme. Besides the TN graphics, the Desktop and titlebar gfx elements would seem to depend from the current size. The installed plugins also expect at least a certain width into which their icons fit. So, maybe the new feature would be to make TN width into themable property... Then somebody could make a thumbless theme. ;-) - Eero ___ maemo-developers mailing list maemo-developers@maemo.org https://maemo.org/mailman/listinfo/maemo-developers
[maemo-developers] automatic byte order check
Hello, I had a look at the vncviewer and saw, that it is working in the sandbox in connection with vino (gnome vnc server). On the device the CoRRE encoding does not work. Probably it is a byte order problem. The code has a lot of byte order (e.g. GUINT16_TO_BE). Is there a way to automaticaly warn critical points at compilation? Are there any tools?

Re: [maemo-developers] automatic byte order check
Hello, The (linux) kernel has endianess-aware integer types (__be_u16 or something similar) which allow the access to be checked for endianess problems (basically reading an endianess-annotated type into a non-endianess-specified (ie native endianess) type must go through a byte order macro). You have to annotate by hand all shared structures with these types. In your case, this would be all network-shared structures. I'm not sure the compiler does the check though, it may be an external tool. It could be however very interesting to generalize this outside of the kernel.

Re: [maemo-developers] problem with dspmp3sink (was: problem with gstreamer and dsppcm)
Siarhei, Just in case you have not done it already, enabling swap in your device can help a lot to prevent out-of-memory errors.Maybe this will help with mplayer/gstreamer stability. I personally suspect a design flaw in the current Linux VM subsystem. I've observed that if an application allocates memory rapidly, the kernel may fail to reclaim pages quickly enough from the page and buffer caches (they are only caches after all), so it actually denies the allocation request. For example, with zero swap, on a machine with 1G of ram, and 500M of it pseudo-free (used by caches), I've seen moderate allocations fail--like when starting an application like firefox.Enabling even a small amount of swap seems to dramatically change this behaviour. -- Buck Eero Tamminen wrote: Hi, Also I noticed that gstreamer is not very reliable, at least when using it from mplayer.

Any cool ideas are warmly welcome. Well, if you're going to go that broad... I think there are a few 'little' things that could be put into the hardware to make it more interesting. (okay, as I kept typing this e-mail got to more than that...) - Light sensor. I really miss having the backlight controlled by the available light like on my Powerbook. - Accelerometer. I'm not sure exactly what this would be used for, but I think it has interesing applications. Perhaps use with GPS to over time get more exact coordinates? Maybe take gesture based browsing to the next level? - Recharge over USB. I realize this is more a Motorola Thing rather than a Nokia Thing. But, for those who travel, reducing the number of power supplies needed is a wonderful gift. - Full MMC slot. I don't know about the space, and I don't really want the device to be bigger, but MMC cards are much easier to find (have several at home already) - Better handwriting recognition. It's usable, but could be much better. It would also be really cool if it was open source. - Voice support. Things like read my IMs or speak a webpage would be nice while doing other things. I'm not aware of any device that has this well integrated and that 'just works.' But, people have talked about it for years and years, I still want it. - Xara. The Xara folks have a really, really, fast renderer without using hardware support. I think it would be really cool to have a version of Xara that would work on the 770. I think they're a company that is trying to figure out where to go with the MS graphics announcement. I don't think they'd port it to the 770 without encouragement from Nokia. I do think it would be a very nice tool on the 770 though. - Bonjour. I've heard (but never tried) that if a bunch of Macs are sitting around, they can find each other and IM using Bonjour. The example relayed to me was at a conference the reporter wasn't close enough to the speaker to get a good picture. So, he got on IM and found someone closer to send him a picture. It would be very cool to do similar stuff, and connect to the same Macs, through the 770. - LEAP support. I'm not sure if Cisco allows anyone to know about LEAP, especially in an open platform.

RE: [maemo-developers] Modified initfs with onscreen boot menu
So, assuming you had the correct partitions set up on an RS-MMC/MMCmobile card beforehand... You -could- install the modified bootprompt initfs to the 770's flash -once-, and then ship releases of Sardine in such a manner that all you'd need to do is `dd` the various stages to high(er) numbered partitions on the card. Extra points to Nokia/Maemo.org if they add this loader code into the flasher application. ;-) Swap cards, and you can boot to Sardine. Swap them back, and you have your regular environment. ... And n'er the twain shall meet. (R. Kipling) As an added benefit, the flash memory blocks you're burning out by reflashing constantly are on the RS-MMC/MMCmobile card, and //NOT// on the board-mounted flash memory. :-) If my math is right, you'd need an RS-MMC/MMCmobile card of at least 256 MB. Street cost of these is negligible compared to the cost of the 770. That would give you: xxx12 MB (256,000,000 Bytes vs. 256 MB loss) P0 -DOS Partition Table Descriptior P1p* 48 MB Memory Card fs P2p 4 MB (Sardine initfs + scratch) P3p 128 MB rootfs+userfs P4E -DOS Extended Partition Table Descriptor P5e64 MB swapfs 256 MB Anything above that point would be partition 6 (extended), and non of the OS's business. :-) -JMills From: [EMAIL PROTECTED] on behalf of Carlos Guerreiro Sent: Mon 21-Aug-06 12:58 To: Marius Vollmer Cc: maemo-dev List; ext Frantisek Dufka Subject: Re: [maemo-developers] Modified initfs with onscreen boot menu Marius Vollmer [EMAIL PROTECTED] writes: Also, I already have a small UI improvement suggestion: what about always showing the boot menu, not only when you hit the MENU key?

I mostly keep track of my activities at my blog [http://tonikitoo.blogspot.com/]. Instruction to install it via repository is also there [2]. The port is not complete yet (so as the minimo development): bug and coming features will make it better, but it surfers on the web greatly. NOTE: As firefox' , minimo's UI is not built using GTK-based as GUI, but XUL instead, which is not Hildonizable currently. NOTE2: menus are on right/left bottom buttons. NOTE3: virtual keyboard thumb-mode and handwrite recognition supports are not implemented yet, so it requires normal vkb for inputting. Any feedback is appreciated.
