2010-09-19 00:45 <qwebirc93545> has anyone figured how to boot the gui on debian for the nanonote?
2010-09-19 08:57 <qi-bot> [commit] Werner Almesberger: ben-baseframe-bottom-500um is done. http://qi-hw.com/p/ben-scans/1fd036e
2010-09-19 09:17 <rafa> wpwrak: what is the problem with clocks?
2010-09-19 09:17 <rafa> wpwrak: we have not touched nothing about .. so i do not have idea where to check if you need some info from jlime and clocks :)
2010-09-19 09:47 <wpwrak> rafa: good morning ! how's the head ? :) the problem is with the clocks gmenu2x in openwrt is messing with
2010-09-19 09:47 <wpwrak> rafa: at least in the latest "official" image, which is from june. so maybe this has changed since.
2010-09-19 09:59 <mth> the gmenu2x in git has been modified to use a cpufreq driver if one is present and otherwise it does not modify the clock frequencies
2010-09-19 09:59 <kristianpaul> whz was modified?
2010-09-19 09:59 <kristianpaul> why
2010-09-19 09:59 <mth> because it's dangerous to poke into registers via /dev/mem
2010-09-19 10:00 <kristianpaul> hehe
2010-09-19 10:00 <kristianpaul> noo ;)
2010-09-19 10:00 <bartbes> lol, so that's why there's a poke program now?
2010-09-19 10:01 <mth> poking is useful for testing things, but it's not a long term solution
2010-09-19 10:01 <kristianpaul> well in mobile/emdebbed stuff i bet is verz commmon
2010-09-19 10:01 <rafa> wpwrak: ah.. okey.. well, we do not do anything like that
2010-09-19 10:01 <mth> a lot of bad practices are common in embedded ;)
2010-09-19 10:02 <kristianpaul> lol
2010-09-19 10:02 <kristianpaul> mth: so zou think i should make a driver to drive io? and other stuff?
2010-09-19 10:02 <kristianpaul> mth: btw what was doing gmenu with /dev/mem what it needed?
2010-09-19 10:03 <mth> it was reprogramming the CPU and other clocks
2010-09-19 10:03 <kristianpaul> ohh
2010-09-19 10:03 <kristianpaul> he want we linux ;)
2010-09-19 10:03 <kristianpaul> we/be
2010-09-19 10:03 <kristianpaul> ahh the cloks !
2010-09-19 10:03 <kristianpaul> power saving
2010-09-19 10:03 <kristianpaul> sound too?
2010-09-19 10:04 <mth> the sound clock is not derived from the PLL freq afaik
2010-09-19 10:04 <kristianpaul> ok
2010-09-19 10:04 <kristianpaul> zear: are you aware off issues realted woth gmenu?
2010-09-19 10:05 <kristianpaul> woth/with
2010-09-19 10:05 <mth> in general, if I/O is exclusively to one device and there is no need to handle interrupts and it is very device specific (no opportunity for creating an abstract interface) then it would be OK to do I/O directly from userland imo
2010-09-19 10:05 <kristianpaul> i agree
2010-09-19 10:05 <mth> but with the CPU clock there is a generic interface for that (cpufreq) and there is interaction with other drivers (many clocks derive from the PLL freq)
2010-09-19 10:06 <kristianpaul> indeed
2010-09-19 10:07 <kristianpaul> why we dont have dmenu in the nanonote?
2010-09-19 10:07 <bartbes> because I worked so hard on gmenu2x.. :P
2010-09-19 10:07 <kristianpaul> :)
2010-09-19 10:07 <mth> if you want to experiment, you can merge the cpufreq driver from my git tree: http://github.com/mthuurne/opendingux-kernel
2010-09-19 10:08 <mth> I'm not sure how much power is saved by lower frequencies though, since the CPU goes into idle mode when there is nothing to do
2010-09-19 10:08 <mth> on the Dingoo people use it for overclocking rather than underclocking
2010-09-19 10:09 <kristianpaul> but but, what other drivers will required cpufreq in plaform/feature specific devices like the nanonote?
2010-09-19 10:09 <mth> the cpufreq driver is not mature yet, it can crash and likely will if you use the on-demand governor
2010-09-19 10:09 <kristianpaul> well i bet in dingoo in is different bacuse the game oriented features
2010-09-19 10:09 <wpwrak> mth: (gmenu2x switch to cpufreq) ah, that's much better then, thanks.
2010-09-19 10:10 <kristianpaul> or let used to a 200Mhy nanonote ;)
2010-09-19 10:11 <kristianpaul> mhz*
2010-09-19 10:11 <mth> dmenu is nice if you have a few programs, but gmenu2x can handle larger numbers of programs well
2010-09-19 10:11 <kristianpaul> you mean multi tasking?
2010-09-19 10:12 <kristianpaul> or sort of that...
2010-09-19 10:12 <mth> no, the number of programs displayed in the menu
2010-09-19 10:12 <kristianpaul> ok i got the point
2010-09-19 10:12 <kristianpaul> hmm i remenerb last gmenu was able to add command line programs :)
2010-09-19 10:13 <kristianpaul> so bartbes is doing great ob :)
2010-09-19 10:13 <kristianpaul> job*
2010-09-19 10:15 <kristianpaul> talking about kernelcan i hack mz linux to limit the number of threads allowed to run?
2010-09-19 10:16 <mth> in theory you can hack in anything, but why do you want that feature?
2010-09-19 10:16 <kristianpaul> well i want ensure better timimg response to handle IO traffic
2010-09-19 10:17 <mth> wouldn't thread priorities be a solution to that?
2010-09-19 10:17 <kristianpaul> well i was aware of thread priorities ;)
2010-09-19 10:17 <kristianpaul> as i said ißm a kernel newbie
2010-09-19 10:18 <mth> I mean, it doesn't matter how many threads there are, it only matters that your I/O thread runs when it should
2010-09-19 10:18 <kristianpaul> zeah
2010-09-19 10:18 <kristianpaul> zes
2010-09-19 10:18 <mth> but the lowest latency you'll get if you write a driver and handle interrupts
2010-09-19 10:18 <mth> then just put the data in a buffer and do more expensive processing from user land
2010-09-19 10:19 <kristianpaul> i want use ram and sd as much as i can
2010-09-19 10:19 <kristianpaul> i think NAND is slow..
2010-09-19 10:19 <kristianpaul> compared to SD
2010-09-19 10:19 <kristianpaul> but i dont know wnought zet#
2010-09-19 10:19 <kristianpaul> yet*
2010-09-19 10:19 <mth> you can test by copying a fixed amount of data using "dd"
2010-09-19 10:19 <mth> from /dev/zero
2010-09-19 10:19 <kristianpaul> mth: i cant handle 2mhy of interrupts
2010-09-19 10:20 <kristianpaul> well i must leave or plain will dropme out, cya in some hours
2010-09-19 10:20 <kristianpaul> thanks mth :)
2010-09-19 10:21 <mth> run
2010-09-19 10:21 <mth> run "sync" after "dd" and time the complete sequence
2010-09-19 10:21 <mth> otherwise the write cache might distort the picture
2010-09-19 10:21 <mth> or just copy a very large amount of data, then the cache won't have a big influence
2010-09-19 10:22 <rafa> wpwrak: a little of headache  :)
2010-09-19 10:24 <kristianpaul> lol
2010-09-19 10:24 <kristianpaul> bye
2010-09-19 10:25 <wpwrak> rafa: i was surprised how difficult it was for me this morning to properly rotate a 3d shape ... :) this was the orientation i was looking for http://projects.qi-hardware.com/index.php/p/ben-scans/source/tree/master/data/jpg/ben-baseframe-bottom-1mm.jpg
2010-09-19 10:25 <wpwrak> and this is what i got after several minutes of trying. http://projects.qi-hardware.com/index.php/p/ben-scans/source/tree/master/data/jpg/ben-baseframe-bottom-500um.jpg
2010-09-19 10:26 <bartbes> kristianpaul: I really only modified the sd card stuff
2010-09-19 10:32 <mth> Ayla did a lot of fixes on gmenu2x
2010-09-19 10:45 <rafa> wpwrak: ;-)
2010-09-19 10:53 <tuxbrain2> Do anyone here , lost his screen on NN? all system seems ok(checked by ssh) and it can usb.boot, I can even play music due I remember the key sequence to start blindly gmu, but screen does't turn on. it is an unopened realatively brand new NN just flashed  three or four times, the same I do the video, so it works totally ok, but I have dried the batt, and I have not touched it for two or tree days, and when I want to use it again , nor on batt, nor
2010-09-19 10:53 <tuxbrain2>  usb power(with or without batt) the screen is totally black
2010-09-19 10:56 <mth> sounds like the backlight is not working
2010-09-19 10:57 <tuxbrain2> any clue on how to recover it?
2010-09-19 10:57 <mth> check for broken connections, I guess
2010-09-19 10:57 <mth> I don't know the NN hardware very well
2010-09-19 10:58 <tuxbrain2> mth that was on of my guesses, but I want some assessment before... estrage due I have not messed inside with this one
2010-09-19 10:58 <mth> afaik it has a separate controller for the backlight
2010-09-19 11:03 <tuxbrain2> I must leave is some one has some clue or experience on this I will read the log.
2010-09-19 11:39 <kyak> hm.. i was able to create a custom font (with cyrillic glyphs) for use with setfont2.. cyrillic input/output works fine after setfont2/loadkeys/loadunimap, but the font looks terrible. Unfortunately, unclouded has been away for quite some time now, and i don't know what font/settings he used to create fonts for setfont2
2010-09-19 11:46 <kristianpaul> back
2010-09-19 11:47 <kristianpaul> mth: so i do dd if=/dev/zero of=foo
2010-09-19 11:47 <kristianpaul> follow by sync?
2010-09-19 11:49 <kristianpaul> oh i see numbers now
2010-09-19 11:49 <kristianpaul> :)
2010-09-19 13:19 <mth> kristianpaul: you can specify block size and block count to copy an exact amount of data
2010-09-19 16:24 <wolfspraul> shutting down the servers for scheduled downtime now... (server moving to new data center)
2010-09-19 16:28 <wolfspraul> according to our ISP they will be down for up to 9h, oh well
2010-09-19 16:28 <wolfspraul> happy travels!
2010-09-19 16:28 <wolfspraul> :-)
2010-09-19 22:53 <mth> kristianpaul: you can use the "time" command to see how long it took
