#rockbox log for 2010-03-09

00:02:42domonokyi think rbutil fails on 10.4 ppc because of the mac tts acting up somehow. and the 10.4 intel rbspeex just uses the wrong sdk. that leaves us with noise with rbspeex on 10.4 ppc and intel
00:06:43pixelmajust to clarify - the TTS itself works fine there. So it can "only" be the integration in RbUtil (or another sdk issue). I'd love to test a different TTS but I'd need to find a binary that works on 10.4 PPC and gave up searching earlier (haven't tried too long though). If someone has a link I'd be thankful, I really don't want to compile anything on those Macs
00:08:41pixelmaan espeak binary or similar that is
00:09:35Stephen__could a themesite admin delete my basicblueart and basicblackart the original author has his versions up aswell and it seems a bit silly having both up. and as he is the original author his should stay.
00:09:38domonokybluebrother mentioned that the tts interface is somehow different in 10.4 so i think its that what causes the rbutil hangs on 10.4 ppc.

01:01:33funmanre: r25082 : does gcc warn about dead code by default ?
01:02:03funmankugel: when trying the same diff than you, gcc wouldn't give a warning, so it might ignore dead return statements
01:03:04kugelfunman: I think it doesn't see that it's dead code
01:04:07kugelexit is a macro which expands to a differently called function. maybe the new gcc doesn't get trapped by the pure "exit" anymore. or it's more stupid if you like
01:05:38kugelI think 4.4.x has a new feature, __attribute__((never_reached)), maybe they gave up some detection in favor of letting devs decide themselve
01:06:20kugeloh, that was 4.5
01:06:47kugeland it was __builtin_unreachable()
01:07:04funmankugel: when disassembling the function (for arm), the return was removed (so gcc saw it was dead code)
01:07:37kugelinteresting
01:07:40funmaniiuc, longjmp() was marked as noreturn, perhaps based only on the function name
01:07:51kugelthen I guess the warning sensitivity has changed
01:08:17kugelI think it's good if it warns and still optimises it away
01:09:25funmanah, longjmp (in setjmp_arm.S) doesn't use bx lr but rather the opcode for it, so perhaps gas sees it as no return
01:11:00kugeldo you think gas removes the return?
01:11:19kugeldid you check gcc -S as well?
01:11:33funmanno i didn't
01:11:49funmando we support armv4 non -T CPUs ?
01:12:07kugelno
01:12:12 Quit Schmogel (Quit: Miranda IM! Smaller, Faster, Easier. http://miranda-im.org)
01:12:32kugelwell, there's no target. I assume we would support them as we don't do thumb anyway :9
01:12:36funmanthen setjmp_arm.S could perhaps be changed (and an extra warning introduced?)
01:12:36saratogai think pre -T CPUs were well before mp3 players
01:12:55kugelfunman: that file is imported, we rather avoid to change imported code
01:13:36funmankugel: only if it harms syncing. one-liner doesn't, and I doubt we would need to sync it in the future considering the small size
01:13:53kugelwhat would you like to change?
01:14:28funmanRET => bx lr
01:14:39funmanit would save 8 bytes of binsize !

02:52:17saratogan1s: it got marginally faster
02:52:30saratogabut thats mostly because we have no ASM at all for CF, not even for simple stuff like butterflies

02:52:56n1sah, nice, there are a few places that stand out as good asm candidates :)
02:53:16saratogayeah everywhere theres arm asm :)
02:53:30saratogabut FFT8 is a pretty obvious place, FFT16 woudln't hurt either
02:53:45n1smainly gcc basically doesn't use movem so it does a lot of move.l stores which can stall etc
02:53:46saratogathe transform macros using EMAC would help a lot

03:39:33ConnorHello, I have a question about rockbox on my 5.5G 80 gig iPod Video. Whenever I pick a song from my database, the iPod pops up a "searching for files" box, and it scrolls from 2700 to 0, and then plays the song. I have the database loaded to ram and dircache enabled. Any way to fix th
03:41:21n1ssaratoga, kugel a nice way to find the optimal O level is to do what Unhelpful did when he made those benchmarks: remove all the individual codec O flags and set it in the codecs.make and then do 3 test runs over the test set, at O1, O2 and O3 and just compare logs
03:41:36Connorn1s you ever hear of this bug?
03:41:43ConnorOr, what I believe to be a bug?
03:41:56n1snope, never used database
03:42:04Connorn1s what mp3 player are you using?
03:42:08saratogamaybe try searching the forums
03:42:12ConnorIt didn't help much.
03:42:14saratogai doubt many people up at this hour have used the database
03:42:20n1si have a h300, c200v1 and gigabeast
03:42:39Connorsaratoga what do you recommend doing?
03:42:47ConnorAside from not using the database.
03:43:07saratogaeither searching or asking during the day on IRC
03:43:07kugelwell if only a test_codec run would last an hour or so :(
03:43:09S_a_i_n_tJdGordon: Around?
03:43:18n1sConnor: so what problem does this cause?
03:43:33n1skugel: that's why the beast is nice :)
03:43:39Connorn1s a 10-20 second delay in a song starting to play.
03:43:49n1sah, it takes that long
03:43:53ConnorYeah
03:44:11kugeln1s: you can hardly compare its performance to the PPs one can you ?
03:44:14ConnorI'll try it not saved to ram.
03:44:52kugelConnor: how big is the list you're selecting
03:45:01Connorkugel 2700 songs.
03:45:02n1skugel: no, you probably can't but a full test_codec run takes much less than an hour
03:45:11kugelit enqueues all songs in the current list, so it may take a while to fetch all and put them into a playlist

03:45:56ConnorHmm. How do I keep the songs from being put into a playlist?
03:46:02ConnorOr is this required?
03:46:02saratogaoh so you're creating a 2700 song playlist
03:46:09ConnorI guess?
03:46:11n1sah, yes it's basically a limitation in the design of the database/playlist stuff
03:46:31ConnorI just want to play my music without a 20 second delay of picking a song from the list of songs to the time the music actually starts.
03:46:31kugelConnor: browse something which gets you a smaller list

03:46:58ConnorSo there's nothing I can do?
03:47:16n1sConnor: <n1s> Connor: make you database searches return fewer results or i suppose long press the son and insert it
03:47:29kugeldon't choose 2700 song lists. I'm sure the database has enough filters which lead to smaller lists
03:47:55ConnorWell I usually have music on shuffle.
03:48:12kugelis that 2700 all of your songs?
03:48:31ConnorYes.
03:48:42kugelI'm not sure why you need the database then
03:48:53saratogacouldn't you just make a single playlist with all your songs and shuffle that?
03:49:05saratogainstead of endlessly regenerating a new one from the database
03:49:13kugelyou could simply go to resume playback after boot without even entering the database. or, once you play all those songs save the playlist on disk
03:49:30ConnorHmm, how would I play my music without the database then?
03:49:58saratogaplay the playlist

03:50:46saratogai think the problem is that you're trying to create a gigantic playlist everytime you use the database, which your slow cpu can't handle well
03:51:01saratogaso i'm saying just save the playlist to disk and play it instead of trying to regenerate it everytime
03:51:05Connorsaratoga I think that is the problem.
03:51:10ConnorAnd how would I go about saving the playlist?
03:51:30saratogai don't know the buttons on your player, but its in the manual
03:51:44saratogaor of course you could always do it on your PC from iTunes or whatever
03:52:17kugelConnor: in the main menu->playlists->save current playlist
03:52:24ConnorThank you.
03:52:32TheSevenhm, what is the charging time estimate based on?
03:52:39ConnorAnd all I have to do is select a song, have it build the playlist, and then save it?
03:52:41TheSevenis it assuming a linear charging curve?
03:53:05kugelConnor: that should work yes
03:53:11ConnorThank you
03:54:32TheSevenand is battery_level_dangerous just a warning level, or causing a shutdown?
03:54:45n1sTheSeven: i think it's done the same way as discharging but with a different curve
03:55:05kugelTheSeven: I think it shuts down at that level
03:55:16kugelbut I'm not sure
03:55:19TheSeventhe existence of battery_level_shutoff proposes the earlier, but my ipod did shut off at "dangerous" during the bench
03:55:43TheSevenn1s: the difference is that while discharging has a more-or-less constant current, the charging on li-ion is highly non-linear
03:56:16saratogaon most targets we have no access to current, so I assume its all based on voltage
03:56:29TheSeventhere is a voltage to percentage mapping for charging, but no mapping to charging time
03:56:32kugelI think the battery estimation is based on the current voltage and the CURRENT_* defines from the config file
03:56:47TheSevenare there current_* things for charging?
03:57:11kugelI think there is one
03:57:31TheSevenreading the current won't help either, what we really need is a mapping from percentage to remaining charging time
03:57:42kugelmaybe not
03:57:53TheSeven(and no, a constant doesn't suit that purpose at all)
03:58:34*TheSeven wonders where that charging time estimation code is
03:59:02n1sTheSeven: it is done the same way for both charging and discharging but with different curves mapping percent to voltages
03:59:51TheSevenn1s: the voltage to percent part is clean, i'm just saying that we would also need a percentage to charge completion time mapping
04:00
04:00:11n1sneed for what?
04:00:22TheSevento predict the charging time
04:00:37n1sah, yes
04:00:49TheSeven(and the "voltage while charging" mapping is somewhat superfluous if we have a battery that's calibrated well)
04:01:43n1si think that the time estimation is now just done by reading the voltage at an interval, and then extrapolating from percent charged over a window
04:02:05TheSevenwhich doesn't make any sense either for li-ion
04:02:44 Quit Strife89 (Quit: Bed.)
04:03:43TheSeven powermgmt_est_runningtime_min = (100 - level)*battery_capacity*60 / 100 / (CURRENT_MAX_CHG - runcurrent());
04:03:45TheSevenaha.
04:03:58n1sit's most likely a thing from the archos days
04:03:58TheSeventhat doesn't make any sense at all
04:05:02TheSevenit's assuming a 100% efficiency of the battery, a constant input current until it is 100% charged, and that the power consumption of the player will be deducted from that, which ist just *all wrong* for nano2g
04:05:50TheSevenon nn2g (if we allow it to draw 500mA) it will do a CC chage at 120mA until the voltage hits 4.32V and then do a CV charge at that level from that point on
04:06:22n1syeah, i was wrong, i though power_history list was used by apparently that is only used by the debug menu and the archos charging code
04:06:45TheSevenif we limit it to 100mA, the archos or whatever scheme will fit better, as during the CC phase, the input current will be limited to 100mA, so the battery current will be 100mA minus the player's current consumption
04:06:55n1sTheSeven: yeah, most li-ion chargers should be the same
04:07:21TheSeventhe funny thing is that there doesn't seem to be a charge completion event
04:07:35TheSevenit will keep the battery floating at 4.32V until you remove USB power
04:07:57TheSevenbut then, if you re-plug it, it won't start charging unless it's below some limit (in the range of 4.2V somewhere)
04:10:01n1staht's a bit weird
04:10:43TheSevenand i haven't yet foudn a GPIO that indicates whether it's actually charging, which is a bit nasty
04:17:30chrisbare links supported? MUSIC/Beethoven/Symphony5.ogg MUSIC/VonKarajan/Symphony5.ogg can these be links?
04:17:54S_a_i_n_tThe OF must know its charged somehow....as it displays a fullscreen battery cell to indicate charging is finished.

12:21:37MarctraiderJust tried installing iloader on my iPod Nano Black 2G yesterday but I kinda screwed up afterwards. Not totally but I cannot seem to get back to my old state. But, it did worked. So you can add me to the list of 7 tested devices ;)

12:24:35MarctraiderI did make back-ups of the files appleos.bin and norflash.bak but i cannot seem to recover them. Tried to write them back with ipodpatcher for nano 2G with all different parameters and it did write to the firmware partition successfully but nothing changes. iloader keeps appearing at the ipod. Also uninstalling the bootloader succeeded and when repeating it it said bootloader already uninstalled, but iloader keeps appearing..
12:25:05Marctraideralso dd'ing random data in linux to /dev/sdd and sdd1/sdd2 every possible way. Nothing changes :(
12:25:37Marctraiderperhaps someone knows how this is happening or has the same problem
12:26:04S_a_i_n_tyou need to flash norflash bask to nor, but you'll need to ask TheSeven about how exactly to do that.
12:26:16MarctraiderOhh ok
12:26:59Marctraideryes well.. the ipod starts with a recoveryscreen 'norloader' and quicky says to switch the hold switch and i do and then ibugger pops up
12:27:20Marctraiderbut this norloader screen only appears for 10ms or so haha
12:27:42MarctraiderBut I think i'll just have to wait for the TheSeven then.
12:27:49S_a_i_n_tat the present state (with norloader installed) even if the apple OS is in the firmware partition, and the bootloader is installed to OSOS, the device isn't really aware of this...
12:28:06S_a_i_n_tas the norloader takes no notice of them
12:29:04S_a_i_n_tbut it does sound very wrong, it will probably flash up quickly like that if the iLoader directory is not on the disk
12:29:12S_a_i_n_tor if it cannot find the right files.
12:31:44S_a_i_n_tTheSeven will be asleep at the moment, but I'm sure he won't mind if you PM him and let him know the state you've got yourself into. He wrote the installer, iLoader, iBugger...and a good deal of code for the Nano2g...so he really is the authority on this.

12:50:26Marctraiderliar: ok
12:50:55Marctraiderbut norloader popups just 10ms when resetting ipod and instantly goes to iloader
12:51:16Marctraiderin that 10ms it tells to switch the hold button. When i do it starts ibugger.
12:51:21liaryes, thats normal
12:53:32liari dont understand the problem, do you want to uninstall norloader?
12:53:36MarctraiderI DID manage to change one thing... namely that I got another screen with 3 options; telling there is a flash error or something. Then it gives me three options: Disk mode, ibugger, and something else. but this is also still part of the iloader.. I find it strange if ipodpatcher tells me it uninstalled iloader it still loads. But i'm not that into this stuff so i can be very wrong ofcourse.
12:54:16TheSevenwoops
12:54:21*TheSeven needs to catch up

13:17:54amiconnThe assembler can't handle it because you effectively turn the next one or two instructions (or one insn plus one extension word) into data
13:19:28amiconnI used this in two places: The remote lcd driver for the irivers, and the bit-banging i2c for the pcf50606 on H300, X5 and M5
13:20:06amiconnLibspeex also uses this in the filters on coldfire
13:21:00amiconnOh, and the dsp code
13:22:54n1sso that's why grep gave no hits
13:24:21amiconnIf you grep for 'trapf' you'll find those places, because they say in a comment what this .word means
13:24:40amiconn(apart from the one in dsp_cf, since that says 'tpf')

13:29:13n1saha, you only have to .word encode the trapf instr not the following ones, that makes it nicer
13:35:32n1samiconn: thanks, i had misunderstood it a bit and thought you'd have to use .word for the instructions following the trapf

13:44:41S_a_i_n_tTheSeven: I think I may have found a reason as to why the Nano1g is so much slower than the Nano2g...can you take a look at this please?
13:44:42S_a_i_n_thttp://pastebin.com/jeJnV1JL
13:45:33S_a_i_n_tIt seems a little odd to me, but I don;t know much about the CPU's of either target, or the similarities and differences.
13:45:59TheSeventhat looks sane, as it specifies the *default* freq
13:46:19TheSeven(which is the highest possible on nano2g, and the lowest possible on nano1g for some reason)
13:47:08TheSevenbut soon after boot, the boosting code will take over and adjust that dynamically (between 48 and 192MHz on the 2g, and between 24 and whatever on the 1g)
13:47:52linuxstbS_a_i_n_t: The Nano1g has an 80MHz CPU - I would expect it to be slower...
13:48:48TheSevenlinuxstb: we're talking about a ~factor 50 slowdown during disk accesses or whatever, making the pictureflow init take a minute on the 1g and a second on the 2g
13:49:01TheSevenS_a_i_n_t: erm, regarding your symmetry thing, it's totally unusable for me
13:49:10TheSevensomething seems to have went wrong with it ;-)
13:49:26S_a_i_n_theh...why's that?
13:49:53linuxstbIs that problem evident just in pictureflow?
13:50:20TheSevenit seems to assume a wrong screen size, scrollbars, icons and the backdrop are missing, and the wps is some brown unreadable mess that looks roughly like the default wps, just in weird colors
13:50:27amiconnTheSeven: The default freq is usually the one that can be used with the pll disabled
13:50:38S_a_i_n_tas long as you have the right fonts, it should run sweet. ;/
13:50:45amiconnIt is not used during normal operation, apart from the radio screen when not recording
13:50:45TheSevenamiconn: that would be 32kHz on the 2g then :-P
13:50:50S_a_i_n_tthat's really fucking screwed up...
13:51:28amiconnThe frequency used during operation is the *normal* frequency, unless the cpu can't cope, in which case we switch to the *max* frequency (boost)
13:51:35TheSevenskin buffer: 57.8K used
13:52:01TheSevenwhere is cpu_freq used at all then?
13:52:20amiconn?

13:55:53TheSevenS_a_i_n_t: oh nice. rebooted it, and now i just get a black screen
13:56:17TheSevenand that's with a build without the ftl changes
13:56:43TheSeveni read the files back from the ipod and compared, they're fine
13:58:02S_a_i_n_tSomething *must* be fucked up on your end...or *perhaps* its currepted somehow on the RB server...but I doubt it.
13:58:23S_a_i_n_tI have the same theme running on 2 1g's and 2 2g's here at home.
13:58:40TheSevenif i just load the wps, i'll get the default wps instead
13:58:52amiconnTheSeven: It is mostly used in a target specific way
13:58:58S_a_i_n_tand it has been check out by perfectdrug on a sim he built...and reported it worked fine ;/
13:59:39amiconnOn targets without boosting it's also used to define the operating frequency in general
14:00
14:00:19TheSevenamiconn: I set it to the operating frequency during boot (which is also the PLL speed, boosting is just done through divisors)
14:00:37amiconnCPU_FREQ is a fixed value
14:01:20amiconncpu_frequency is reflecting the current value, and gets initialised to CPU_FREQ
14:01:26TheSevenwrong evaluation order ;-) (I set it to the (operating frequency during boot ))
14:03:05amiconnSo you can use CPU_FREQ on Nano G2 as you want. Having a CPUFREQ_DEFAULT that's fairly low would probably make sense though
14:03:31amiconn(although I don't think there are many occasions when this frequency is chosen - Nano G2 doesn't have a radio, does it?)
14:03:55TheSevenonly through accessories
14:04:05TheSeven(which aren't implemented yet)
14:05:11*amiconn thinks he found the bug that caused the non-working battery bench
14:05:53amiconnThere is a pair of functions to hook into a "disk is spinning" status. register_storage_idle_func() and unregister_storage_idle_func()
14:06:23amiconnThe latter can optionally call the registered function (a last time, directly), and battery_bench uses that
14:06:43amiconnBut if the target in question doesn't implement storage callbacks, that doesn't work

15:00:52MarctraiderTheSeven: thanks i'll check it out
15:00:56Marctraiderand report back
15:01:17Marctraideri thought with ipodpatcher you could uninstall the bootloader and everything was fine, but i thought wrong i guess ;)
15:01:43TheSeventhat only applies to the old osos bootloaders, not to the nor ones
15:02:04Marctraiderok
15:02:27TheSevenyou actually need to *reinstall* the old apple bootloader, overwriting iloader, and the place where it is stored can't be accessed directly from a pc
15:06:31Marctraidermhh ok
15:06:43Marctraiderim trying the uninstaller now as we speak
15:07:22MarctraiderI assume one has a problem if one doesnt have norflash.bak backupped?
15:07:23Marctraider:p
15:07:44S_a_i_n_t.....yes.
15:08:24Marctraiderok. Well thats not the case dont worry, but i just thought about it
15:08:35S_a_i_n_t*phew*
15:08:42S_a_i_n_tyou freaked me out there...
15:08:43TheSevenwell, *in theory* one could build it from several pieces scattered around in apple firmware images and the iloader flash, but that won't be fun and requires some more advanced tools and knowledge about how this stuff works
15:09:01S_a_i_n_tits not *so* bad, but you could never have a "stock" ipod again.
15:09:09S_a_i_n_t*if that were the case that is.
15:09:10MarctraiderAnd i have one more question. The actual reason why i wanted to try this is because i wanted to edit the apple firmware to get rid of that stupid EU volume limit.
15:09:20Marctraideri see
15:09:21 Quit moos (Quit: ChatZilla 0.9.86 [Firefox 3.6/20100115144158])
15:09:47MarctraiderI have edited an appleos.bin to remove the EU volume cap, can i use this one to replace my original?
15:09:50S_a_i_n_tit is easy to "uncap" the ipod
15:10:00TheSevenyou can also do that without iloader, but it will require decrypting, patching and re-encrypting the firmware
15:10:02S_a_i_n_tTheSeven could point you to a link I believe
15:10:15Marctraiderehm
15:10:24TheSeven(which is well possible, just a bit of work)
15:10:28Marctraiderwell ill try to uninstall first, uncapping comes later i guess
15:10:57TheSevenuninstall = copy 2 files and reboot it, then restore using itunes
15:10:58*S_a_i_n_t lives in NZ...so has iPods that can deafen him :D
15:10:59S_a_i_n_thehe
15:11:21MarctraiderTheSeven: aight!
15:11:25*TheSeven didn't notice *much* difference in the output levels whether it's capped or not
15:11:54TheSevenand afterwards you can patch the firmware using ibugger, ipodcrypt and ipodpatcher
15:11:55Marctraiderdo i need to rename it to iLoader.conf or .cfg?
15:12:01TheSeven.cfg
15:12:03Marctraiderok
15:12:08TheSevendid i misspell it somewhere?
15:12:18Marctraideri think so
15:12:29Marctraidercfg vs conf
15:12:33TheSevenok, fixed
15:12:39Marctraiderno serious thing though ;)
15:12:45Marctraideri was just confused for a sec
15:12:53Marctraiderbrb
15:12:56TheSeventhat's why it needed to be fixed ;-)
15:13:05S_a_i_n_tAnd with it uncapped, or with Rockbox which the "capping" is unaffected bym an iPod Nano 1st/2nd gen is plenty capable of destrying a cheap pair of IEM's
15:13:30S_a_i_n_teven a halfway decent pair...if you take it up past 0dB
15:14:00TheSevenmy nano won't go above -1dB with 16 Ohms headphones
15:14:30S_a_i_n_t*wont* go, or sounds shit if you go past?
15:14:41Marctraiderdoes the iloader screendissapear in some time or do i now just have to restore with itunes?
15:14:42TheSevenboth
15:14:56TheSevenMarctraider: which screen exactly?
15:14:57Marctraiderok the screen goes of but nothing happens
15:15:06*S_a_i_n_t got himself some sennheiser IE8's
15:15:11Marctraiderplease press play and extract an iloader theme etc etc. Iloader free your nano!
15:15:21TheSevenhm, it didn't find the iloader.cfg file then
15:15:27TheSevenpress play and fix it
15:15:34Marctraiderok
15:15:37Marctraiderbrb
15:15:52S_a_i_n_tI can take both my 1 & 2 g's up to -6dB...but it sounds pretty dodgy past -3
15:16:07TheSevenS_a_i_n_t: it sound shit *because* the output amplifier can't go above -1dB, or actually 20% less at 16 ohms
15:16:31S_a_i_n_tthe IE8's can take then punishment on -6db...but your ears can't (not for long anyway)
15:16:38 Quit DerPapst (Read error: Connection reset by peer)
15:16:58TheSevenso the actual output level the headphones get will be around -3dB maximum. the amp isn't capable of supplying more
15:17:28kugelarg, this stupid data abort
15:17:44kugelhow can I debug those better than getting the failure address?
15:17:46S_a_i_n_tAhhh...so the reading of -6 is not actually true?

15:18:11kugelI would like a reg dump and/or the current ins
15:18:17TheSevenyou mean +6?

15:18:41S_a_i_n_tsorry, forgot to shift
15:18:50TheSevenmaximum RMS output power of the amp is ~32mW, which is -3dB
15:19:11TheSeven(which you'll get when setting it to -1dB, due to some inaccuracies)
15:19:25TheSeveneverything above that will just clip at 16 ohms
15:19:35S_a_i_n_tHmmm...howcome it displays up to +6dB then?
15:19:48S_a_i_n_toh, right. I get it now.
15:20:17TheSevenit will apply up to +6dB to audio data that doesn't go above -9dB ;-)
15:20:45n1skugel: you can hack up the exception handler to print a regdump etc
15:21:07TheSevenbtw, when it's feeding into a line load instead of headphones, it will reach +1dB (and the setting will be accurate)
15:21:10kugelI think funman once had a patch for that stuff
15:21:19n1syes
15:21:47TheSevenn1s: why didn't that go into svn?
15:22:30*TheSeven likes the "crashkernel" approach, that would also allow to get a memory dump and look at the hardware
15:23:04kugeln1s: it seems to be on the tracker (grepping logs is awesome :) )
15:23:19n1sTheSeven: i think it was because it used some cpu feature that some cpus were missing or something like that
15:23:46TheSevenwe should be able to get around that, at least for ARM, which would be quite helpful for a start
15:23:59n1syeah, it was arm only afaik
15:24:12kugelthis one should be committed
15:24:19n1sbut you should ask funman or whoever was against it :)
15:24:30n1skugel, whic fs#

15:31:27kugelis there a armv5 which doesnt support it?
15:31:56preglowi doubt v4 supports those
15:32:11kugelwe could extend our ARM_ARCH define to include some bitmask for certain features
15:32:32preglowwhy not just check for the arm revision? most features are consistent across revisions
15:32:37kugelpreglow: 922t does, at least
15:33:18funmanTorne knows the details, the registers are present if a MMU or a MPU is present
15:33:31preglowyeah, that's what i expected, most v4s don't have that, if any
15:33:49funmansansa AMS at least do
15:34:11kugelso, why would the cpu throw a data abort on address 60B4AE04? does it know where an address is good or bad?

15:37:25kugellr - 8 seems to the be the fault address
15:37:29funmanTorne: well i'll let you do ;) i try to look for a good place in headers to discriminate CPUs
15:37:57Tornefunman: well your code is fine for armv5, but it won't work for prefetch/undef on armv6 as they have a separate IFSR :)
15:38:32kugelfunman: the fault is in an .S function, btw

15:39:40kugelyes
15:40:03kugelit doesn't seem to be caused by short enums, I added a dummy with the value of INT_MAX to all

15:42:06n1sfunman: pnx0101 is arm7tdmi iirc and the only port using it is dead
15:42:51kugelfault 8 is "precise external abort, nontranslation" apparently
15:44:47*kugel still thinks we should remove dead ports from svn to make it easier for people to work on active code
15:46:47n1skugel: it's not in they way much
15:46:55funmanTCC780x DM320 and S3C2440 do have an mmu (they use mmu-arm.S), I don't know about TCC77x (iaudio7/m200/c100/logikdax, all abandonned?), AT91SAM9260 (lyreproto1 = abandoned?), DSC25 (archos av300 = no code = abandoned) and S5L870x (meizus, nano2g)
15:47:43kugeln1s: what's the point in keeping them? It's not like we can't recover their code from the svn history
15:47:48funmans5l870x have a mmu code so they're ok (why specific code btw?)
15:48:55n1skugel: true but since tey don't really get in the way i don't think removing them is very important but i wouldn't be against it
15:49:05Tornefunman: well, if they have a "standard" ARM cache or MMU or MPU they must have CP15
15:49:25funmanI see that tcc77x manipulate cp15 cache registers
15:49:56Tornedo we not have a CPU type define of some kind?
15:50:07kugelfunman: non-standard caches I believe
15:50:08Torne#define ARM946EJ-S or similar
15:50:16funmanTorne: no, only V4 V5 and V6

15:53:06funmanTorne: hm or MMU_PRESENT ? this would make #ifdef simpler if we only check this information in system-arm.c
15:53:33Tornefunman: Well, I would suggest that we define the specific CPU type in the target configs
15:53:44Torneand then use that to infer a bunch of other defines like MMU/cache/etc
15:53:54Torneand then use *those* to enable specific code
15:54:04TorneThis is probably a reasonable amount of effort from where we are now though

16:22:33n1sit appears to mean jtag basically
16:22:46TorneJTAG is a protocol, ICE is a thing to access over it :)
16:25:46Tornefunman: you probably want to print the entire FSR, not just the bits from it, because some of the other bits mean something on various processors
16:25:58amiconnkugel: That call looks fishy. The new gcc version is a bit short to tell what it's actually trying to do
16:26:00Torneand some of htem mean something but aren't documented publicly :)
16:26:24kugelit also appeared fishy to me
16:26:32amiconnYou can clearly see that either r0 or r1 must be wrong, because they're identical when calling mpeg2_idct_add()
16:26:41funmanit appears only the arm7tdmi (PP, pnx0101, dsc25 SoCs) don't have those registers
16:26:56kugelcompiling with -O0 would show how it expects the parameter passing, right?
16:27:22amiconnfunman, Torne: There already is a macro for arm7tdmi specifically
16:27:33Torneamiconn: this isn't the only feature that should be conditional on chip type, though
16:27:48Torneamiconn: all the MMU/cache stuff should really be derived from ARM CPU type, not from target

16:31:09Tornejust i suggest you make it print the whole FSR val instead of just those two fields
16:31:26funmanalthough I could move the check after the known-to-be-working button check, i'm a bit lazy those days :)

16:32:27TorneWell, do the armv6 stuff too
16:32:36Torneit's basically just checking IFSR instead of DFSR
16:32:47TorneDFSR on ARMv6 is at the same place as the unified FSR on armv5
16:32:59Torneso you just need to check a different cp15 reg if it's a prefetch abort.
16:33:15Torne(and obviously for prefetch abort, the FAR is irrelevant, it's lr that tells you where the abort was)
16:33:17funman'on armv5' => but it's the same on armv4 & armv5 ?

17:07:26Tornekugel: You still have to save r0-r3
17:07:43kugelwhy?
17:07:45Tornecalling them const only guarantees that the called function doesn't assign to those variable *names*, it says nothing about the registers
17:07:51TorneThe function is still free to overwrite r0-r3
17:08:05TorneThe parameters don't necessarily stay in those registers.
17:08:20kugelgood point
17:08:23Tornethe const *only* protects you from accidentally assigning to the params when you meant to write something else

17:35:10amiconnkugel: Is that only for this function, or all functions?
17:35:21amiconnIn fact that looks like a gcc bug to me
17:35:28funmanTorne: isn't cp15 mandatory & standardized on armv6 ?
17:35:34UnhelpfulTorne: ...ah... i think my error was in thinking funman was replying to your <Torne> anyone know what ARM1136 revision the i.MX31 is? :)
17:35:46kugelit's possible that other functions are hit as well
17:35:56funmanUnhelpful: but i was ! :)
17:35:59ThomasAHFlynDice: clock works fine for me after setting it on both sides in the correct order :)
17:36:05amiconnWe could work around it by reordering the parameters of the idct_* functions. Of course that needs adjusting all asm implementations, not just arm
17:36:13ThomasAHFlynDice: or clocks as in ram speed and such?
17:36:34kugelI think the problem is exposed by the fact that mpeg2_idct_add() is written in asm. if it was written in C it would probably follow the same strange calling convention gcc dictates here
17:36:49FlynDiceThomasAH: er not the time but fclk, pcclk etc...
17:36:51Unhelpfulkugel: what "strange" calling convention?
17:37:00Tornefunman: yes.. we should do that, just not on arm7tdmi :)
17:37:25amiconnThis *might* because the 2nd and 3rd parameters are pointers - gcc may consider them as (potential) 64 bit parameters, so r1 is skipped
17:37:34kugelUnhelpful: the gcc generated call appears to violate the standard calling convention
17:37:49ThomasAHFlynDice: this is for running without disabled caches I assume?
17:38:03Unhelpfulamiconn: ...are pointers 64b on ARM? and since when?
17:38:26amiconnNo - that's why I said it may be a gcc bug
17:38:37kugelamiconn: that wouldn't make sense. how can it put something into r3 if r2 was a 64bit type (i.e. would take space in r3 as well)?
17:38:50amiconnAnd also why I asked whether it's just this function, or all
17:38:57Unhelpfulkugel: what if you cast the pointers to uint?
17:39:06Unhelpful(in the call)
17:39:50FlynDiceThomasAH: Not sure, but the clocks setup right now just "happens" to work so perhaps that will help. Right now the as3525 fclk is at 6 MHz... clk_main(24MHz)/4

17:41:28kugelamiconn: I assume there's no crash as long as the called function is also compiled by gcc
17:41:51ThomasAHFlynDice: I'm not familiar with such details. fclk is like the FSB speed on PC hardware?
17:42:03FlynDiceThomasAH: That's wrong, FCLK is 120 MHZ PCLK is at 6 MHz
17:42:08amiconnYes, but there are numerous asm functions in the core as well
17:42:15amiconn...e.g. ata transfer
17:42:45kugelmy hdd based yh925 behaved fine in the core
17:43:04kugelit appears to be dependant on the order of the parameters as well. swapping the 2nd and 4th one helps
17:43:19kugel(in the prototype only)
17:43:40FlynDiceThomasAH: and the bus is fastbus mode which means the processor is only clocked at 6 MHz right now
17:45:17ThomasAHFlynDice: thanks for the explanation, I probably have to read more about it

17:49:04amiconnWhat's the earliest gcc supporting eabi?
17:49:28Torneamiconn: the ABI is fine, but other than that I can't say :)
17:49:39FlynDicemt: I didn't need this until a few days ago but I think funman's clip+ needed it all along
17:50:09funmanFlynDice: storage should be initialized after LCD, so i'm not sure if that's the problem
17:50:21amiconnWell, the reason why I am wondering is because two of those parameters are pointers, and two are ints
17:50:43amiconnIn svn they are int/ptr/ptr/int, and that causes the strange gcc behaviour

19:32:53amiconnSo it could be worked around by using an intermediate variable?
19:32:59kugelyes
19:33:21fmlBuschel: actually, I don't quite like both. The reason is that in many places, the tables with the buttons directly follow section captions which isn't good style. I tried to eliminae the not needed table envs since they are there for nothing. We even fight their nature (being floating) via redefining placement to H (=here!, i.e. not floating at all)
19:33:23amiconnEh, volatile?

21:29:11Digital_PioneerHi. I'm trying to install rockbox on a friend's Fuze, following this tutorial: http://ubuntu-tutorials.com/2009/06/12/install-rockbox-on-your-sansa-fuze/ and nothing happened...
21:30:08banzairunhi, I'm a dumbass newb asking a question that likely has an obvious answer that I nonetheless can't find on the web page...

21:30:50banzairunI just installed rock box on an ipod video 80gb 5.5g
21:31:15banzairuncan I get my clickwheel itunes store games to work from the rockbox interface?
21:31:55Farthenbanzairun: no, they don't work in rockbox. but you could boot the original apple firmware
21:32:10banzairunthanks
21:32:17banzairunhow do I switch between them?
21:32:38Fartheni think you need to hold the left arrow key right after you have reset it
21:32:59banzairunoh so prob like left is one OS and right is the other?
21:34:18Farthenno, it starts rockbox if you do nothing. and if you press the left arrow key it starts the apple firmware
21:34:44FarthenDigital_Pioneer: is it a fuze v1 or a v2?
21:34:47Buschelbanzairun: please see the manual -> turn on Hold switch immediately after turn on.
21:34:51banzairunok how disappointing tho... was hoping for ipod install0us :)
21:35:04FarthenBuschel: ooops, then i mixed them up ;-)
21:36:32Digital_PioneerFarthen: Pretty sure it's a v1, it just calls itself a Fuze.
21:38:03kugellook at the OF version, it must be 1.xx.xx
21:38:11FarthenDigital_Pioneer: then i'd suggeset to just follow the manual here: http://download.rockbox.org/daily/manual/rockbox-sansafuze.pdf
21:39:36kugelDigital_Pioneer: I highly recommend you to use our automated installer, Rockbox Utility, instead of downloading a suspicious package from someone
