00:46:39CIA-81New commit by Buschel (r28165): Add current consumption and battery capacities to iPod nano 2G config file.
00:47:46*TheSeven likes the fact that Buschel steals items from his todo list :)
00:48:16Buschel:-) the battery bench and the discharge curve is still missing though
00:48:21CIA-81r28165 build result: All green
00:48:33*TheSeven committed a discharge curve once
00:49:34TheSevenhm, someone stole that, too
00:50:09Buschelyes, there is one. but to me it seems the included one will reach 0% too early
00:50:27Buschelbtw, any chance to work on LCD_SLEEP?
00:50:40Buschelthis might bring in some more savings...
00:51:37TheSevenah, there it is
00:51:40TheSevenit only moved a bit
00:51:43TheSevenconst unsigned short percent_to_volt_discharge[BATTERY_TYPES_COUNT][11] = { { 3550, 3783, 3830, 3882, 3911, 3949, 3996, 4067, 4148, 4228, 4310 } };
00:51:50TheSevenlooks fine to me
00:53:35TheSeveni tweaked the lowest two values a bit to give a better average accuracy in the nearly-empty area
00:54:56TheSevenshutoff at 3.35V was needed so that the ipod has enough charge left to do a worst-case ftl commit (about 30 seconds of writing to flash)
00:55:05Buscheldon't you think it would be better to even use lower voltages for "dangerous" and "shutoff"? both are >>3.0V which is the lowest voltage used player internally (from what I can see)
00:55:10TheSeventhe flash is powered through an LDO linear regulator at 3.00V
00:55:30TheSevenso we need to still be a bit above of that to make it work in a stable fasion
00:55:31Buschelah, you just typed the answer for the question I was asking
00:56:00Buschelso, then the battery stuff is finished :)
00:56:03TheSeventhe voltage falls rather fast starting at about 3.30V
00:56:17TheSevenat 2.90V the CPU will die
00:56:52TheSeveni don't know if the power manager shuts it off deliberately or if it just fails because the RAM voltage drops too much (it's also configured at 3.00V)
00:57:17TheSeventhe CPU internally runs at 1.00V or 1.05V through a switching regulator
00:57:47Buschelis it possible to use lower voltage when the cpu is clocked down to 48 MHz?
00:58:08TheSevenyes, I managed to get it down to 0.95V but that doesn't save much
00:58:25TheSevenit even seems to run at that voltage at 200MHz
00:58:40Buschelwhat were the savings?
00:58:47Buschel<1 mA?
00:58:47TheSevenmaybe 1mA
00:59:04TheSeventhe problem is that the XTAL oscillator frequency drops noticably below 0.925V on mine
00:59:25TheSeventhis was reported to happen at even higher voltages on some devices
00:59:52TheSeveni once managed to run it at 0.85V at 48MHz, but the real cpu clock was more like 43MHz
01:00:30*TheSeven didn't know that xtal oscillators can behave that badly
01:00:53TheSeventhe problem with frequency-dependent undervolting is that switching the voltage takes way too long
01:01:11TheSevenapparently the cpu frequency change function can be invoked from an IRQ context
01:01:30 Quit insp_ (Quit: ChatZilla 0.9.86 [Firefox 3.6.8/20100722155716])
01:01:36TheSevenand we need to wait for I2C transactions to complete and voltages to stabilize before raising the clock again
01:01:50TheSevenif that could be split into multiple operations, this might help
01:01:59TheSevenbut I can't block IRQs for that long without disrupting playback
01:02:25Buschelso, best would be to either find a lower voltage that also fits for 192MHz or just keep the actual voltage
01:02:49TheSeventhat I2S core is extremely sensitive to FIQ latencies
01:02:50 Quit s1gma_ (Ping timeout: 265 seconds)
01:03:11TheSevenmore than about 20 *microseconds* of latency until the next DMA transfer is started and you'll notice clicking
01:03:48TheSevenso we can't even afford to lock FIQs while waiting for a PLL to lock
01:04:25TheSeven(that's why I'm using an assembly FIQ handler)
01:04:40Buschelthat's why you are using the fastbus-option to force the cpu clock to 48 MHz?
01:04:52 Join Nausicaa [0] (
01:04:57TheSeveni can't stop the pll, because I don't manage to get it running again fast enough
01:05:35TheSevenif we would change the core in a way that allows boosting/unboosting to be split into multiple operations, that might help
01:05:50TheSevenor at least get rid of the calls from IRQ context
01:05:58TheSeventhat would allow us to block at least
01:06:07TheSeventhen we could also change the voltage
01:06:17TheSevenpowering down the unused PLL saves about 2mA IIRC
01:06:40Buscheldo we already do this?
01:06:47soapHas any disassembly been done on the OF?
01:06:57TheSevena bit, but not much of it
01:07:25TheSevenmost of it was reverse engineered from the apple bootloader and diagmode
01:08:02soapI'm curious if any knowledge has been gleaned on how the OF manages the CPU frequency, since it sounds much harder to maximize part-turnoff-savings than on the previous ipods I was curious if the OF even bothered.
01:08:25*TheSeven has no idea
01:08:29soap(not that I have ANY insights, just curiosity)
01:08:51TheSevenone might want to look at their FIQ handler
01:09:02TheSeventhey might have found a better way to deal with the I2S DMA
01:09:26TheSevenauto-reloading DMA didn't work for me for some reason, and they didn't use it in diagmode at all

01:14:51BuschelTheSeven: the LCD driver has lots of waits between each 16 bit write access to the 16bit data register. if I remove one of those waits between 2 write accesses, the speed is increased and i can see no visible impact to the screen.

01:33:04TheSevensorry, webchat went dead for some reason
01:33:16TheSevenbut in the meantime i had a quick glance at the OF's FIQ handler:
01:33:19TheSevenSTMFD SP!, {R0-R12,LR}
01:33:39TheSevenapparently they didn't quite realize what kind of advantage an FIQ offers in terms of registers
01:33:52 Quit PaulJam (Ping timeout: 272 seconds)
01:33:59TheSevenso I think they aren't suffering as bad from the latency problem as we are
01:35:13TheSevenactually an FIQ seems to be considered a fatal error
01:37:15CIA-81New commit by Buschel (r28166): Roll back r28164 as this change introduced LCD issues on some nano 2G.

01:46:30TheSevenif you need init code, there's some code in norloader/embios loader that should do the trick, but it's a bit fishy
01:47:11TheSevenalso IIRC there's a patch on flyspray that's dealing with LCD shutdown, don't remember if it was yours or liar's or someone else

11:05:47 Join bertrik [0] (~bertrik@rockbox/developer/bertrik)
11:05:51n1siirc the codecbuffer is at the end of the audiobuffer so if we alloc too much we could overwrite that
11:06:20JdGordonand also the order is close enough to random to causing problems... a bunch of non-essential buffers could be being allocated (and work) before a big essential buffer
11:07:37n1sthat really has nothing to do with proper eror checking, but sounds like it needs a think-through

11:08:40JdGordonkugel: not after audio is init-ed though...?

11:10:20JdGordonbertrik: we could do that with logf just as easily though... if there is no protection then timestrecth+skin buffer could probably be naughty, should be just a matter of checking the audio buffer size int he debug screen though
11:12:14pixelman1s: codecbuffer is unlikely because I see problems on my hwcodec target too
11:12:19gevaertsExcept that logf isn't any good in official builds
11:12:49JdGordonof course, but that sounds like a waste in regular builds also
11:13:17gevaertsHow many buffer_alloc()s does a regular running system do?
11:13:51n1spixelma: ah
11:14:00JdGordonif audio playback works at all then it is almost certainly not the actuall alloc() which is causing problems
11:14:18JdGordongevaerts: hundreds if dircache is enabled
11:14:33gevaertsWe're talking about a few lines of code, and a few bytes (8? 16?) of metadata (length+magic value to check) in before and after each block I think
11:14:35JdGordonotherwsie I'd guess a dozen or so
11:15:26gevaertsMight still be a good idea to implement, even if it's not added to default builds
11:15:55gevaertsEven if the issues we're talking about now probably aren't related, some issues in the past have definitely been
11:19:24JdGordon*cough* proper buflib
11:19:33bertrikyeah, we could make this extra administration optional (#ifdef it) if people object to the few extra bytes it takes
11:19:56bertrikwe could also store some kind of thread id with the blocks to know who allocated it
11:20:30JdGordona string would be more useful, just about all would be on the main thread
11:20:38bertrikand have a debug screen with stats
11:22:29gevaertsI think having buffer_alloc() check if there's enough room and panic if not should be there

14:13:43gevaertsYes, that would make sense
14:13:58gevaertsAnd easy to do, actually
14:14:07JdGordonespecially when it is pretty much impossible to reboot the android app currently

14:19:18bertrikTheSeven, no, I just reverted to an earlier version to make it work again
14:19:38JdGordonso that makes sure the file actually has a chance of being usable because the pointer is the same as last boot?

14:37:48JdGordonunsigned char* should be safe no?
14:38:29JdGordonbuffer_front = (void *)(((unsigned long)buffer_front + 3) & ~3); <- not entirely safe?
14:39:17gevaertsintptr_t sounds better
14:39:30amiconn'long' isn't guaranteed to be large enough to hold a pointer
14:39:51amiconnOn linux x86_64 it should work though, but it will break on win64
14:39:53JdGordonI dot think that is the problem though, that would cause the crash the 2nd time not first time, I'll fix it anyway
14:39:56bertrikis the cast to unsigned long (or anything else) really needed anyway?

14:44:15amiconnWell, you could cast outside the inner ( ), but if you do this with anything else than [unsigned] char* you will confuse people, probably even yourself

14:48:22gevaertsJdGordon: did you include stdlib.h?
14:48:55gevaertsIf not, C assumes that a function returns int, which messes with the pointer that malloc() returns

14:50:32kugelJdGordon: btw, I think you should fix up size, not the pointer
14:50:45gevaertsYes, I was going to suggest that too
14:50:48bertrikyeah, I wondered about that too in buffer.c
14:51:15gevaertsIf you round the size up, the pointer will stay aligned
14:51:25gevaertsAnd size is never that big, so you're fine by definition :)
14:51:36JdGordonnot my code :)
14:51:47gevaertsI actually changed that in buffer.c

14:57:49CIA-81r28175 build result: All green
14:57:53n1steru: sounds like a good idea
14:57:54JdGordongevaerts: oh SHIT! you serious? :'(
14:58:04gevaertsJdGordon: that's what it looks like anyway
14:58:12bertrikteru, png can also be greyscale, right?
14:58:16n1ssurely there are other filetypes not supported on all targets
14:58:45gevaertsrolo too, but I don't think that matters much here
14:58:56AlexPGive wodz a few minutes and png will be on greyscale too :)
14:59:14JdGordonwe can disable dircache on hosted though :)
14:59:14teruwodz: yeah, nice work. but same situation could happen in the future. for example when someone add gif viewer only for color target.
14:59:24gevaertsah, good call :)
14:59:30gevaertsWe probably should, anyway
14:59:37gevaertsIf it's not already
14:59:37kugelAlexP: actually, I think he managed greyscale already and is now adding greylib support (i.e. even nicer :) )
14:59:51kugelit is disabled
15:00:48AlexPkugel: Yeah, it already works
15:00:57gevaertsJdGordon: ok, dircache is fine. Now fix tagcache.c which does that too :)
15:00:59AlexPI was using it last night :)
15:01:15kugelthe host does caching, and it's not reasonable to cache the entire filesystem on a real machine
15:01:43kugelignoring the general breakage with recursive symlinks :)
15:02:09JdGordonarg, tagcache is sort of needed though
15:02:31kugeltagcache works as far as I can tell
15:03:19gevaertskugel: yes, but you didn't rip out buffer_alloc() :)
15:03:31gevaertsJdGordon: looks like an easy fix there though
15:05:47n1sbtw, having the properties plugin in the viewers list makes no sense
15:07:27JdGordongevaerts: did you change dircache.c to not be naughty?
15:07:42gevaertsIf it's disabled anyway, who cares?
15:08:06JdGordonIdeally nothing should use audiobuf directly
15:08:31gevaertsI'm trying to find out why that tagcache audiobuf abuse is safe (I assume it is, there aren't enough crash reports for it not to be...)
15:08:55JdGordonbecause it happens early probably? /me hasnt had a look yet
15:09:17gevaertsThat's what I'm looking for. From what I can see, it can happen at any time...
15:09:58GiovaJdGordon: One of the latest build has fixed the bug #11626
15:10:17JdGordon(to both above messages :p )
15:11:45terun1s: I'm not sure how to implement the idea. in my patch, image file types are associated to imageviewer.rock and imageviewer is build for all bitmap targets. so all image file types are included to viewers.config and it causes the issue.
15:11:47Leargevaerts: Only during tagcache init, as far as I can see...
15:12:04n1steru: aha
15:12:11gevaertsLear: oh, right
15:12:28JdGordonyeah 4417 seems scary, but probably safe? untill we get preemtive scheduling
15:12:29*gevaerts missed the #ifdef __PCTOOL__
15:13:23n1sbut tagcache.c should call buffer_alloc and not do this directly anyway, right?
15:13:24gevaertsI assume commit() does file IO, which could yield as far as I know
15:13:43kugelteru: just preproces viewers.config?
15:14:11gevaertsoh, and it sleeps, which definitely yields
15:14:48*TheSeven knows why he doesn't like cooperative multitasking
15:14:49gevaertsSo yes, that bit could well be responsible for weird hard to reproduce issies
15:14:55Leargevaerts: But the main thread waits for the initialized flag or something to be set (hence the "in foreground" comment).
15:15:07gevaertsLear: but do other threads?
15:15:21gevaertsWell, other threads shouldn't be buffer_alloc()ing anyway I guess
15:16:27JdGordonthe buffer isnt required after the commit so there must be a better way to do this
15:16:40JdGordonwhich would also mean not neeing a reboot to commit
15:17:12gevaertsIt could steal the plugin buffer :)
15:17:38JdGordonany ideas how much it needs?
15:17:40*gevaerts finds dircache_steal_buffer()...
15:18:23gevaertsIt grabs the entire audio buffer basically
15:18:39kugelJdGordon: it needs exactly 32*1024*1024
15:18:53gevaertskugel: only if __PCTOOL__ is defined :)
15:18:56kugeloh, that's the pctool case
15:19:06gevaertsSo it's "safe" in the sense that no other allocations can mess up its idea of the world
15:19:17kugelwell, I stronly suspect it won't need more on the dap
15:19:17n1s32MB would be kind of hard on most targets ;)
15:19:44kugelerr, that's 32*M*B, oops (/me thought K)
15:21:36*JdGordon notes there is no locking on the plugin buffer also
15:23:05n1sthat's why it's so much fun hunting bugs, you usually dig up a whole bunch of bad things...
15:23:06kugelthat tempbuf code is strongly suspicious in any way
15:23:21kugelwhat if the audio buffer isn't big enough? it could overwrite codec or plugin buffer
15:24:05JdGordonI'm replacing it with plugin_get_buffer() and removing the dircache steal
15:25:02kugelhopefully it won't clash with skin engine which also uses the plugin buffer?
15:25:18gevaertsJdGordon: that may well be too small...
15:25:30*gevaerts doesn't like that code either
15:25:53JdGordonkugel: Lear said the main thread waits for init so it should be safe, but yes a proper fix is also needed
15:25:55*TheSeven suggests just throwing everything away and rewriting it from scratch
15:26:17JdGordongevaerts: I'm working on the assumption that it doesnt care how much it has, but the more the merrier

15:42:45gevaertsBasically unify audio_get_buffer() and buffer_alloc() a bit
15:44:09JdGordonand to overengineer it, allow it to be non-blocking (so fail if it cant get the buffer) and requested_size so more than one thing can borrow a block
15:44:37gevaertsWouldn't you get fragmentation then?
15:44:47TheSevenJdGordon: What about just implementing a proper malloc?
15:44:58JdGordonwell that would be the obvious solution :p
15:45:07gevaertsHow? No MMU, remember...
15:45:22gevaertsi.e. you can implement malloc(), but it won't work well
15:45:32TheSeventhe aim should of course be to make sure that nothing stays allocated for too long
15:46:07JdGordonthe requested_sie thing was me being silly, but not blocking would be useful
15:46:26TheSeventhe audio buffer should just float around in the empty space
15:46:51Jaykayrockbox does work with sdhc cards of all sizes, right? (i plan to buy a 8gb one)

15:47:29JdGordonor trying other potential buffers like the plugin buffer if audio one isnt available
15:47:39JdGordonwhich would be unlikely if this isnt abused

15:48:44gevaertsI wouldn't mind seeing the buflib system that was once proposed, and position-independent plugins

18:52:39m0arMy clip+ has been acting strange the last couple of days, instead of skipping to the next track when pressing >>| it just skips 0.001 sec forward in the song. I have tried to locate the setting, but had no luck. What might I have touched?
18:53:48kugelhow did you measure the 0.001s?
18:54:02m0arMy mind os powerful.
18:54:16m0arkugel: Just estimating, it's prolly like 0.2 or sumting
18:54:41kugeluse real words please
18:55:08m0arkugel: Oh well, If I keep it pressed down it searches the track forward as usuam
18:55:33m0arkugel: but a swift click does not change the track, it just skips an extremely small bit forward
18:55:36m0arGet it?
18:55:58kugelperhaps you have enabled "prevent track skipping"
18:56:55wodzpixelma: when I finish transparency handling I'll provide patch witch will apply cleanly to svn
18:56:59m0arAh damn, I even recall doing that when you mention it

18:57:57kugelit causes some confusion, you're not the first one

19:01:57m0arJust wondering, what is there to solve before the clip+ can be called stable?
19:04:17gevaertsPossibly USB, but also that it's not a good idea (as we noticed with the clip) to promote a target to stable when we're not doing a new release
19:05:25m0argevaerts: You mean filetransferring while connected via usb? What do you mean with the last thing?
19:07:00gevaertsm0ar: basically that declaring a target "stable" should be done at the same time that we release 3.7, or 3.8, or whatever. If it's done in between, various scripts and bits of the website get confused
19:07:45gevaertsThere are now e.g. various links to a 3.6 build for the Clip, which doesn't exist, because the Clip wasn't stable yet when 3.6 was released
19:08:36m0arAh, thank you
19:09:01gevaertsSo we either have to fix those, or just not declare targets stable at random times

21:24:08pleroheroI have a simple question...
21:24:44pleroherowhen a dynamic playlist (not saved) reaches its end it's deleted?
21:26:41pleroheroI usually play one track and then enqueue more tracks... but when the playlist reach its end its erased.
21:26:48clone4crwI think it's erased only when another one is created
21:27:17pleroheroits automatically deleted
21:27:57pleroheroI use file browser to add a directory
21:27:57clone4crwAnd you want to be kept?
21:28:16clone4crwon the main menu playlists > save current playlist
21:28:43pleroheroi dont want it to be physically saved
21:29:27pleroheroi just want to have a persistant playlist lets say
21:30:04pleroherojust like amarok or foobar playlist
21:30:13pleroheroyou add your songs to the playlist
21:30:25pleroheroit plays them in the order you want
21:30:42pleroheroif it ends its not destroyed
21:31:11pleroheronor you have to store it manuallly every time
21:31:46clone4crwoh i see what you mean.
21:31:46gevaertsIt doesn't look deleted to me...
21:32:00gevaertsplerohero: when it reaches the end, there's still Playlists->Current Playlist
21:32:59gevaertsok, that doesn't survive reboot
21:33:32clone4crwno, i think he's going to have to save it to disk.
21:34:37clone4crwSo, I created a playlist of some random songs, and hit stop, and it persists in Current Playlist and can resume it
21:35:05bertrikthis behaviour of rockbox confuses me a bit too
21:35:44gevaertsIt's in a very vague way related to not saving pitch and timestretch settings
21:36:11gevaertsI'd like not using the player for half an hour be the same as shutting it down and booting it again in half an hour
21:36:28clone4crwAnd that playlist is still there after I reboot. huh.
21:36:49gevaertsclone4crw: yes, it's a playlist that *ended* that behaves differently
21:37:17clone4crwOH. I have mine set to repeat all. That's why.
21:37:28gevaertsYes, it never ends then :)
21:38:25pleroheroi thought it was deleted
21:38:40clone4crwOK, so I set repeat to off, and I still see the playlist in Current Playlist
21:38:42pleroheroits in the Playlist->Current playlist
21:39:08gevaertsclone4crw: yes, until you reboot. (unless you just stopped it, which is different)
21:39:42gevaertsA playlist that didn't reach its end is *always* persisted
21:40:24clone4crwYeah, I see now. Hmmm... Think it should be an option to always persist unless a new one is started?

21:41:42pleroheroif i want it stored ermanently i'll use repeat all

21:47:08bertrikplerohero, you mean you expected it to be stopped and rewound?
21:47:13pleroheroI'm not a native english speaker so ignore my mistakes please..
21:47:37AlexPbertrik: It should restart IMO
21:47:46*gevaerts disagrees
21:48:02AlexPHow do I play it again if I want to?
21:48:20slothearnit should stop at the last track if repeat isn't enabled.
21:48:26slothearnbut replay the last track if play is pressed
21:48:28plerohero@alexp you go to playlists->view current playlist
21:48:44AlexPSeems a bit of a long way round
21:48:51gevaertsIf I listen up to the end of a playlist, and then I fall asleep, and the next day I restart the player, and the start screen is set to WPS, should it restart the playlist? If so, why do need repeat modes?
21:49:17AlexPTo restart automatically
21:49:19pleroherobeacuase i'm lazy :-p
21:49:38AlexP(why there are repeat modes that is)
21:49:38gevaertsSo people who *don't* want to listen to the same thing again aren't allowed to be lazy?
21:49:43pleroherobecause i'm lazy :-p
21:49:59AlexPgevaerts: How does it impact you if you don't want to listen again?
21:50:26gevaertsAlexP: I have to stop playback and leave the WPS first
21:50:41AlexPOK, I see that if you have it set to WPS on start
21:50:52gevaertsWhich is about as many keypresses as you need to go to current playlist and start again :)
21:51:05gevaerts(provided it gets saved)
21:51:21AlexPI don't actually mind if play restarts it or not, it just seems that the method of restarting is a bit baroque
21:51:32AlexPAnd yes, the real issue is the not saving it

21:51:40slothearnhere's a question, why do I sometimes have to use multiple keypresses on an iPod 5G?
21:51:55slothearndoesn't always work the first time. I've noticed this :O
21:52:31slothearnit's also very intolerant of accidental presses. like the menu/select reset combo
21:52:44slothearnthat sometimes needs to be like 2-3 times to get it to work.
21:52:59slothearnI'm assuming because my fingers slide ever so slightly and register as scrolls.
21:53:08gevaertsslothearn: I know there has been an issue with the first keypress after leaving a plugin, but I think that's fixed
21:53:20gevaertsApart from that, I'm not aware of any issues
21:53:29bertrikgevaerts, no, it's not fixed, but we do know what causes it
21:53:30slothearngevaerts: I thought it was just my iPod tbh, but it works fine in the official firmware
21:54:01domonoky1slothearn: the reset combo isnt controlled by rockbox, its a hardware feature..
21:54:05AlexPgevaerts: Would it be difficult to save the dynamic playlist? I'm assuming not very

23:16:17pixelmagevaerts: ok, I'll try the first on my Ondio and the latter on the M5
23:16:34nihilanthalright, i'll keep at it. thanks for the encouragement :P
23:16:37Torneit resets eventually, if you hold it long enough, every case we've heard of :)
23:16:57gevaertspixelma: should give you a much bigger main stack on m5, at the cost of less IRAM for plugins/codecs (so there may be some performance problems with some codecs). I'd use that for a while, and check the stack usage in the debug menu every now and then
23:17:17gevaertsThe big thing will be to find out what's using all this stack though

23:24:02pixelmaI remember checking the stack usage when investigating the nested conditionals problem with Lear and he made me check the numbers on the Ondio and it didn't seem too much

23:25:03gevaertsIt's too much onm5 though
23:25:41*gevaerts would like to see 3.7, but this sort of issue really is a release blocker...

23:27:57[AndrewR]hello, I'm trying to write a plugin, and I have rockboxui compiling.. I added my plugin to SOURCES and CATEGORIES, but it's not showing up in the menu
23:28:52[AndrewR]anything else I need to do?
23:29:36gevaertsYou're trying this with a simulator build?
23:29:42gevaertsDid you run make install?
23:30:09[AndrewR]um at some point I think I told it to build simulator, yeah
23:30:22[AndrewR]if I rm rockboxui it rebuilds it with make
23:30:53[AndrewR]the simulator runs, my plugin's just not in the apps list
23:31:16gevaertsDoes your plugin get built?
23:31:25[AndrewR]it does, I see it compiling
23:31:28[AndrewR]to a .rock file
23:31:28pixelmagevaerts: I should really try an unaltered build from after yesterday's fixes first though, I guess - just remembered that I didn't update the M5 today...
23:31:45[AndrewR]I can try make install..
23:31:47gevaertspixelma: ah, yes. Might be useful :)
23:32:02pixelmajust the other two
23:32:27gevaerts[AndrewR]: the sim doesn't get any plugins if you don't do make install
23:32:41[AndrewR]ah, it shows up now, thanks!
23:33:07 Join feisar- [0] (
23:33:12[AndrewR]so I should be doing make install each time?
23:33:25gevaertsOr copy it by hand
23:34:44[AndrewR]ah, ok. thanks

23:41:53gevaerts"%s corrupted buffer %x start" or "%s corrupted %x end", with %s being the thread name, and %d being the address of the buffer
23:42:17pixelmaI'll try that then
