| 00:02:42 | domonoky | i 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 |
| 00:06:43 | pixelma | just 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 |
| 00:08:41 | pixelma | an espeak binary or similar that is |
| 00:09:35 | Stephen__ | 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. |
| 00:09:38 | domonoky | bluebrother 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. |

| 01:01:33 | funman | re: r25082 : does gcc warn about dead code by default ? |
| 01:02:03 | funman | kugel: when trying the same diff than you, gcc wouldn't give a warning, so it might ignore dead return statements |
| 01:03:04 | kugel | funman: I think it doesn't see that it's dead code |
| 01:04:07 | kugel | exit 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 |
| 01:05:38 | kugel | I think 4.4.x has a new feature, __attribute__((never_reached)), maybe they gave up some detection in favor of letting devs decide themselve |
| 01:06:20 | kugel | oh, that was 4.5 |
| 01:06:47 | kugel | and it was __builtin_unreachable() |
| 01:07:04 | funman | kugel: when disassembling the function (for arm), the return was removed (so gcc saw it was dead code) |
| 01:07:37 | kugel | interesting |
| 01:07:40 | funman | iiuc, longjmp() was marked as noreturn, perhaps based only on the function name |
| 01:07:51 | kugel | then I guess the warning sensitivity has changed |
| 01:08:17 | kugel | I think it's good if it warns and still optimises it away |
| 01:09:25 | funman | ah, longjmp (in setjmp_arm.S) doesn't use bx lr but rather the opcode for it, so perhaps gas sees it as no return |
| 01:11:00 | kugel | do you think gas removes the return? |
| 01:11:19 | kugel | did you check gcc -S as well? |
| 01:11:33 | funman | no i didn't |

| 01:12:32 | kugel | well, there's no target. I assume we would support them as we don't do thumb anyway :9 |
| 01:12:36 | funman | then setjmp_arm.S could perhaps be changed (and an extra warning introduced?) |
| 01:12:36 | saratoga | i think pre -T CPUs were well before mp3 players |
| 01:12:55 | kugel | funman: that file is imported, we rather avoid to change imported code |
| 01:13:36 | funman | kugel: 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 |
| 01:13:53 | kugel | what would you like to change? |

| 03:41:21 | n1s | saratoga, 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 |

| 03:48:31 | Connor | Yes. |
| 03:48:42 | kugel | I'm not sure why you need the database then |
| 03:48:53 | saratoga | couldn't you just make a single playlist with all your songs and shuffle that? |
| 03:49:05 | saratoga | instead of endlessly regenerating a new one from the database |
| 03:49:13 | kugel | you 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 |
| 03:49:30 | Connor | Hmm, how would I play my music without the database then? |
| 03:49:58 | saratoga | play the playlist |
| 03:50:19 | Connor | I am confused. |
| 03:50:34 | | Join BiptoN [0] (~4cad70c0@giant.haxx.se) |
| 03:50:46 | saratoga | i 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 |
| 03:51:01 | saratoga | so i'm saying just save the playlist to disk and play it instead of trying to regenerate it everytime |
| 03:51:05 | Connor | saratoga I think that is the problem. |
| 03:51:10 | Connor | And how would I go about saving the playlist? |
| 03:51:30 | saratoga | i don't know the buttons on your player, but its in the manual |
| 03:51:44 | saratoga | or of course you could always do it on your PC from iTunes or whatever |
| 03:52:17 | kugel | Connor: in the main menu->playlists->save current playlist |
| 03:52:24 | Connor | Thank you. |
| 03:52:32 | TheSeven | hm, what is the charging time estimate based on? |
| 03:52:39 | Connor | And all I have to do is select a song, have it build the playlist, and then save it? |
| 03:52:41 | TheSeven | is it assuming a linear charging curve? |
| 03:53:05 | kugel | Connor: that should work yes |
| 03:53:11 | Connor | Thank you |
| 03:54:32 | TheSeven | and is battery_level_dangerous just a warning level, or causing a shutdown? |
| 03:54:45 | n1s | TheSeven: i think it's done the same way as discharging but with a different curve |
| 03:55:05 | kugel | TheSeven: I think it shuts down at that level |
| 03:55:16 | kugel | but I'm not sure |
| 03:55:19 | TheSeven | the existence of battery_level_shutoff proposes the earlier, but my ipod did shut off at "dangerous" during the bench |
| 03:55:43 | TheSeven | n1s: the difference is that while discharging has a more-or-less constant current, the charging on li-ion is highly non-linear |
| 03:56:16 | saratoga | on most targets we have no access to current, so I assume its all based on voltage |
| 03:56:29 | TheSeven | there is a voltage to percentage mapping for charging, but no mapping to charging time |
| 03:56:32 | kugel | I think the battery estimation is based on the current voltage and the CURRENT_* defines from the config file |
| 03:56:47 | TheSeven | are there current_* things for charging? |
| 03:57:11 | kugel | I think there is one |
| 03:57:31 | TheSeven | reading the current won't help either, what we really need is a mapping from percentage to remaining charging time |
| 03:57:42 | kugel | maybe not |
| 03:57:53 | TheSeven | (and no, a constant doesn't suit that purpose at all) |
| 03:58:34 | * | TheSeven wonders where that charging time estimation code is |
| 03:59:02 | n1s | TheSeven: it is done the same way for both charging and discharging but with different curves mapping percent to voltages |
| 03:59:51 | TheSeven | n1s: 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 |
| 04:00:11 | n1s | need for what? |
| 04:00:22 | TheSeven | to predict the charging time |
| 04:00:37 | n1s | ah, yes |
| 04:00:49 | TheSeven | (and the "voltage while charging" mapping is somewhat superfluous if we have a battery that's calibrated well) |
| 04:01:43 | n1s | i 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 |
| 04:02:05 | TheSeven | which doesn't make any sense either for li-ion |
| 04:02:44 | | Quit Strife89 (Quit: Bed.) |
| 04:03:43 | TheSeven | powermgmt_est_runningtime_min = (100 - level)*battery_capacity*60 / 100 / (CURRENT_MAX_CHG - runcurrent()); |
| 04:03:45 | TheSeven | aha. |
| 04:03:58 | n1s | it's most likely a thing from the archos days |
| 04:03:58 | TheSeven | that doesn't make any sense at all |
| 04:05:02 | TheSeven | it'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 |
| 04:05:50 | TheSeven | on 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 |
| 04:06:22 | n1s | yeah, 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 |
| 04:06:45 | TheSeven | if 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 |
| 04:06:55 | n1s | TheSeven: yeah, most li-ion chargers should be the same |
| 04:07:21 | TheSeven | the funny thing is that there doesn't seem to be a charge completion event |
| 04:07:35 | TheSeven | it will keep the battery floating at 4.32V until you remove USB power |
| 04:07:57 | TheSeven | but then, if you re-plug it, it won't start charging unless it's below some limit (in the range of 4.2V somewhere) |
| 04:10:01 | n1s | taht's a bit weird |
| 04:10:43 | TheSeven | and i haven't yet foudn a GPIO that indicates whether it's actually charging, which is a bit nasty |
| 04:17:30 | chrisb | are links supported? MUSIC/Beethoven/Symphony5.ogg MUSIC/VonKarajan/Symphony5.ogg can these be links? |
| 04:17:54 | S_a_i_n_t | The OF must know its charged somehow....as it displays a fullscreen battery cell to indicate charging is finished. |

| 12:24:35 | Marctraider | I 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.. |
| 12:25:05 | Marctraider | also dd'ing random data in linux to /dev/sdd and sdd1/sdd2 every possible way. Nothing changes :( |
| 12:25:37 | Marctraider | perhaps someone knows how this is happening or has the same problem |
| 12:26:04 | S_a_i_n_t | you need to flash norflash bask to nor, but you'll need to ask TheSeven about how exactly to do that. |
| 12:26:16 | Marctraider | Ohh ok |
| 12:26:59 | Marctraider | yes well.. the ipod starts with a recoveryscreen 'norloader' and quicky says to switch the hold switch and i do and then ibugger pops up |
| 12:27:20 | Marctraider | but this norloader screen only appears for 10ms or so haha |
| 12:27:42 | Marctraider | But I think i'll just have to wait for the TheSeven then. |
| 12:27:49 | S_a_i_n_t | at 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... |
| 12:28:06 | S_a_i_n_t | as the norloader takes no notice of them |
| 12:29:04 | S_a_i_n_t | but it does sound very wrong, it will probably flash up quickly like that if the iLoader directory is not on the disk |
| 12:29:12 | S_a_i_n_t | or if it cannot find the right files. |
| 12:31:44 | S_a_i_n_t | TheSeven 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. |

| 12:50:09 | Marctraider | S_a_i_n_t: thanks for the help already I will pm him later today, i've read everything you wrote |
| 12:50:26 | Marctraider | liar: ok |
| 12:50:55 | Marctraider | but norloader popups just 10ms when resetting ipod and instantly goes to iloader |
| 12:51:16 | Marctraider | in that 10ms it tells to switch the hold button. When i do it starts ibugger. |
| 12:51:21 | liar | yes, thats normal |
| 12:53:32 | liar | i dont understand the problem, do you want to uninstall norloader? |
| 12:53:36 | Marctraider | I 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. |
| 12:54:16 | TheSeven | woops |
| 12:54:21 | * | TheSeven needs to catch up |
| 12:54:26 | Marctraider | liar: The prob is i want to recover my ipod and i have 2 back-up files norflash.bak and appleos.bin. |
| 12:54:34 | Marctraider | oh |
| 12:54:44 | S_a_i_n_t | here we go :D |
| 12:55:01 | * | S_a_i_n_t thought TheSeven was still asleep... ;) |
| 12:55:04 | Marctraider | TheSeven: Can i contact you later today for my problem? (I dont blame you ofcourse it was totally my own risk :) |
| 12:55:26 | Marctraider | But I need to take the children out of school |
| 12:55:28 | Marctraider | :( |
| 12:56:01 | Marctraider | I'll be back as soon as i Can, please read what i've posted here TheSeven, see you later today perhaps. |
| 12:56:25 | TheSeven | S_a_i_n_t: I was until a minute ago ;-) |
| 12:56:36 | S_a_i_n_t | hehe :D |
| 12:57:02 | TheSeven | hehe, I didn't build an uninstaller yet, but I can quickly make one |
| 12:57:09 | Marctraider | lol? |
| 12:57:12 | Marctraider | oh! ok... |
| 12:57:25 | Marctraider | be back later ;) |

| 13:15:08 | amiconn | As such, you cannot use it as a mnemonic in the assembler (except the operand-less form, which is essentially a single cycle nop) |
| 13:15:46 | n1s | yeah, that's what i gathered :( |

| 13:16:34 | n1s | doesn't work well with inline asm unless you hardcode the registers, and a single cycle save is probably not worth it |
| 13:17:14 | n1s | i wonder why the assembler can't handle it though |
| 13:17:54 | amiconn | The assembler can't handle it because you effectively turn the next one or two instructions (or one insn plus one extension word) into data |
| 13:19:28 | amiconn | I 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 |
| 13:20:06 | amiconn | Libspeex also uses this in the filters on coldfire |
| 13:21:00 | amiconn | Oh, and the dsp code |
| 13:22:54 | n1s | so that's why grep gave no hits |
| 13:24:21 | amiconn | If you grep for 'trapf' you'll find those places, because they say in a comment what this .word means |

| 13:44:41 | S_a_i_n_t | TheSeven: 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? |
| 13:44:42 | S_a_i_n_t | http://pastebin.com/jeJnV1JL |
| 13:45:33 | S_a_i_n_t | It seems a little odd to me, but I don;t know much about the CPU's of either target, or the similarities and differences. |
| 13:45:59 | TheSeven | that looks sane, as it specifies the *default* freq |
| 13:46:19 | TheSeven | (which is the highest possible on nano2g, and the lowest possible on nano1g for some reason) |
| 13:47:08 | TheSeven | but 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) |
| 13:47:52 | linuxstb | S_a_i_n_t: The Nano1g has an 80MHz CPU - I would expect it to be slower... |
| 13:48:48 | TheSeven | linuxstb: 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 |
| 13:49:01 | TheSeven | S_a_i_n_t: erm, regarding your symmetry thing, it's totally unusable for me |
| 13:49:10 | TheSeven | something seems to have went wrong with it ;-) |
| 13:49:26 | S_a_i_n_t | heh...why's that? |
| 13:49:53 | linuxstb | Is that problem evident just in pictureflow? |
| 13:50:20 | TheSeven | it 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 |
| 13:50:27 | amiconn | TheSeven: The default freq is usually the one that can be used with the pll disabled |
| 13:50:38 | S_a_i_n_t | as long as you have the right fonts, it should run sweet. ;/ |
| 13:50:45 | amiconn | It is not used during normal operation, apart from the radio screen when not recording |
| 13:50:45 | TheSeven | amiconn: that would be 32kHz on the 2g then :-P |
| 13:50:50 | S_a_i_n_t | that's really fucking screwed up... |
| 13:51:28 | amiconn | The frequency used during operation is the *normal* frequency, unless the cpu can't cope, in which case we switch to the *max* frequency (boost) |
| 13:51:35 | TheSeven | skin buffer: 57.8K used |
| 13:52:01 | TheSeven | where is cpu_freq used at all then? |

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

| 15:00:52 | Marctraider | TheSeven: thanks i'll check it out |
| 15:00:56 | Marctraider | and report back |
| 15:01:17 | Marctraider | i thought with ipodpatcher you could uninstall the bootloader and everything was fine, but i thought wrong i guess ;) |
| 15:01:43 | TheSeven | that only applies to the old osos bootloaders, not to the nor ones |
| 15:02:04 | Marctraider | ok |
| 15:02:27 | TheSeven | you 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 |
| 15:06:31 | Marctraider | mhh ok |
| 15:06:43 | Marctraider | im trying the uninstaller now as we speak |
| 15:07:22 | Marctraider | I assume one has a problem if one doesnt have norflash.bak backupped? |
| 15:07:23 | Marctraider | :p |
| 15:07:44 | S_a_i_n_t | .....yes. |
| 15:08:24 | Marctraider | ok. Well thats not the case dont worry, but i just thought about it |
| 15:08:35 | S_a_i_n_t | *phew* |
| 15:08:42 | S_a_i_n_t | you freaked me out there... |
| 15:08:43 | TheSeven | well, *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 |
| 15:09:01 | S_a_i_n_t | its not *so* bad, but you could never have a "stock" ipod again. |
| 15:09:09 | S_a_i_n_t | *if that were the case that is. |
| 15:09:10 | Marctraider | And 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. |
| 15:09:20 | Marctraider | i see |
| 15:09:21 | | Quit moos (Quit: ChatZilla 0.9.86 [Firefox 3.6/20100115144158]) |
| 15:09:47 | Marctraider | I have edited an appleos.bin to remove the EU volume cap, can i use this one to replace my original? |
| 15:09:50 | S_a_i_n_t | it is easy to "uncap" the ipod |
| 15:10:00 | TheSeven | you can also do that without iloader, but it will require decrypting, patching and re-encrypting the firmware |
| 15:10:02 | S_a_i_n_t | TheSeven could point you to a link I believe |
| 15:10:15 | Marctraider | ehm |
| 15:10:24 | TheSeven | (which is well possible, just a bit of work) |
| 15:10:28 | Marctraider | well ill try to uninstall first, uncapping comes later i guess |
| 15:10:57 | TheSeven | uninstall = 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 |
| 15:10:59 | S_a_i_n_t | hehe |
| 15:11:21 | Marctraider | TheSeven: aight! |
| 15:11:25 | * | TheSeven didn't notice *much* difference in the output levels whether it's capped or not |
| 15:11:54 | TheSeven | and afterwards you can patch the firmware using ibugger, ipodcrypt and ipodpatcher |
| 15:11:55 | Marctraider | do i need to rename it to iLoader.conf or .cfg? |
| 15:12:01 | TheSeven | .cfg |
| 15:12:03 | Marctraider | ok |
| 15:12:08 | TheSeven | did i misspell it somewhere? |
| 15:12:18 | Marctraider | i think so |
| 15:12:29 | Marctraider | cfg vs conf |
| 15:12:33 | TheSeven | ok, fixed |
| 15:12:39 | Marctraider | no serious thing though ;) |
| 15:12:45 | Marctraider | i was just confused for a sec |
| 15:12:53 | Marctraider | brb |
| 15:12:56 | TheSeven | that's why it needed to be fixed ;-) |
| 15:13:05 | S_a_i_n_t | And 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 |
| 15:13:30 | S_a_i_n_t | even a halfway decent pair...if you take it up past 0dB |
| 15:14:00 | TheSeven | my nano won't go above -1dB with 16 Ohms headphones |
| 15:14:30 | S_a_i_n_t | *wont* go, or sounds shit if you go past? |
| 15:14:41 | Marctraider | does the iloader screendissapear in some time or do i now just have to restore with itunes? |
| 15:14:42 | TheSeven | both |
| 15:14:56 | TheSeven | Marctraider: which screen exactly? |
| 15:14:57 | Marctraider | ok the screen goes of but nothing happens |
| 15:15:06 | * | S_a_i_n_t got himself some sennheiser IE8's |
| 15:15:11 | Marctraider | please press play and extract an iloader theme etc etc. Iloader free your nano! |
| 15:15:21 | TheSeven | hm, it didn't find the iloader.cfg file then |
| 15:15:27 | TheSeven | press play and fix it |
| 15:15:34 | Marctraider | ok |
| 15:15:37 | Marctraider | brb |
| 15:15:52 | S_a_i_n_t | I can take both my 1 & 2 g's up to -6dB...but it sounds pretty dodgy past -3 |
| 15:16:07 | TheSeven | S_a_i_n_t: it sound shit *because* the output amplifier can't go above -1dB, or actually 20% less at 16 ohms |
| 15:16:31 | S_a_i_n_t | the 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) |
| 15:16:58 | TheSeven | so the actual output level the headphones get will be around -3dB maximum. the amp isn't capable of supplying more |

| 15:17:44 | kugel | how can I debug those better than getting the failure address? |
| 15:17:46 | S_a_i_n_t | Ahhh...so the reading of -6 is not actually true? |

| 15:18:11 | kugel | I would like a reg dump and/or the current ins |
| 15:18:17 | TheSeven | you mean +6? |
| 15:18:18 | S_a_i_n_t | mine goes up to -6dB |

| 15:18:41 | S_a_i_n_t | sorry, forgot to shift |
| 15:18:50 | TheSeven | maximum RMS output power of the amp is ~32mW, which is -3dB |
| 15:19:11 | TheSeven | (which you'll get when setting it to -1dB, due to some inaccuracies) |
| 15:19:25 | TheSeven | everything above that will just clip at 16 ohms |
| 15:19:35 | S_a_i_n_t | Hmmm...howcome it displays up to +6dB then? |
| 15:19:48 | S_a_i_n_t | oh, right. I get it now. |
| 15:20:17 | TheSeven | it will apply up to +6dB to audio data that doesn't go above -9dB ;-) |
| 15:20:45 | n1s | kugel: you can hack up the exception handler to print a regdump etc |
| 15:21:07 | TheSeven | btw, when it's feeding into a line load instead of headphones, it will reach +1dB (and the setting will be accurate) |
| 15:21:10 | kugel | I think funman once had a patch for that stuff |
| 15:21:19 | n1s | yes |
| 15:21:47 | TheSeven | n1s: 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 |
| 15:23:04 | kugel | n1s: it seems to be on the tracker (grepping logs is awesome :) ) |
| 15:23:19 | n1s | TheSeven: i think it was because it used some cpu feature that some cpus were missing or something like that |
| 15:23:46 | TheSeven | we should be able to get around that, at least for ARM, which would be quite helpful for a start |
| 15:23:59 | n1s | yeah, it was arm only afaik |
| 15:24:12 | kugel | this one should be committed |
| 15:24:19 | n1s | but you should ask funman or whoever was against it :) |
| 15:24:30 | n1s | kugel, whic fs# |
| 15:24:30 | Marctraider | ehm |
| 15:24:31 | kugel | the problem seems to be proper #ifdef'ing for ARMs without cp15 |
| 15:24:32 | Marctraider | TheSeven |
| 15:24:42 | kugel | n1s: FS #10296 |
| 15:24:49 | n1s | thanks |
| 15:27:19 | n1s | yeah, just a whitelist #ifdef including it for cores we know have the necessary features should be fine |

| 15:30:52 | funman | FS #10296 displays fault status and address causing the data abort (not the adress _where_ it happened), but we need to examine each model and see if it supports those registers (they are mandatory in ARMv6+, we need to check v4/v5) |
| 15:31:27 | kugel | is there a armv5 which doesnt support it? |
| 15:31:56 | preglow | i doubt v4 supports those |
| 15:32:11 | kugel | we could extend our ARM_ARCH define to include some bitmask for certain features |
| 15:32:32 | preglow | why not just check for the arm revision? most features are consistent across revisions |
| 15:32:37 | kugel | preglow: 922t does, at least |
| 15:33:18 | funman | Torne knows the details, the registers are present if a MMU or a MPU is present |
| 15:33:31 | preglow | yeah, that's what i expected, most v4s don't have that, if any |
| 15:33:49 | funman | sansa AMS at least do |
| 15:34:11 | kugel | so, why would the cpu throw a data abort on address 60B4AE04? does it know where an address is good or bad? |
| 15:34:45 | preglow | i'm wrong, btw |
| 15:34:51 | preglow | loads of armv4s have mmus |
| 15:34:53 | kugel | the address if foobar, btw |
| 15:34:58 | amiconn | kugel: That's not valid ram or rom, is it? |
| 15:35:09 | kugel | preglow: we already knew you were wrong :p |
| 15:35:21 | kugel | amiconn: no |
| 15:35:23 | preglow | yeah, but not the extent to which i was :> |
| 15:35:31 | funman | kugel: you should look at lr and print a bit of stack to see where it comes from (perhaps a borked function pointer?) |
| 15:36:10 | funman | though you will have a different stack pointer so you need to switch to supervisor mode before reading the stack |
| 15:36:21 | Torne | funman: or if they feel like it |
| 15:36:31 | Torne | funman: it has occasionally been present on chips with neither :) |
| 15:36:37 | Torne | it's not there on arm7tdmi though |
| 15:36:52 | | Join evilnick_B [0] (~0c140464@rockbox/staff/evilnick) |
| 15:36:54 | kugel | funman: how can I get lr? |
| 15:36:56 | Torne | funman: also, I was going to work on that patch for you.. |
| 15:37:08 | Torne | funman: to add support for ARMv6 and to make it ifdef'ed right. I just hadn't gotten around to it :) |
| 15:37:25 | kugel | lr - 8 seems to the be the fault address |
| 15:37:29 | funman | Torne: well i'll let you do ;) i try to look for a good place in headers to discriminate CPUs |
| 15:37:57 | Torne | funman: well your code is fine for armv5, but it won't work for prefetch/undef on armv6 as they have a separate IFSR :) |
| 15:38:32 | kugel | funman: the fault is in an .S function, btw |
| 15:39:18 | amiconn | kugel: Is this the mpegplayer crash with eabi? |
| 15:39:40 | kugel | yes |
| 15:40:03 | kugel | it doesn't seem to be caused by short enums, I added a dummy with the value of INT_MAX to all |
| 15:40:15 | amiconn | Subtle difference in parameter passing between old abi and eabi? |
| 15:40:25 | amiconn | Which file+function? |
| 15:41:20 | funman | Torne: We "only" need to check TCC77x TCC780x DM320 AT91SAM9260 PNX0101 S3C2440 DSC25 and S5L870x CPUs |
| 15:41:25 | kugel | I only know that the passing of 64bit types has changed. but the function in question doesn't have those |
| 15:41:42 | kugel | amiconn: idct_arm.S:mpeg2_idct_add |
| 15:42:06 | n1s | funman: pnx0101 is arm7tdmi iirc and the only port using it is dead |
| 15:42:51 | kugel | fault 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 |
| 15:46:47 | n1s | kugel: it's not in they way much |
| 15:46:55 | funman | TCC780x 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) |
| 15:47:43 | kugel | n1s: what's the point in keeping them? It's not like we can't recover their code from the svn history |
| 15:47:48 | funman | s5l870x have a mmu code so they're ok (why specific code btw?) |
| 15:48:55 | n1s | kugel: 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 |
| 15:49:05 | Torne | funman: well, if they have a "standard" ARM cache or MMU or MPU they must have CP15 |
| 15:49:25 | funman | I see that tcc77x manipulate cp15 cache registers |
| 15:49:56 | Torne | do we not have a CPU type define of some kind? |
| 15:50:07 | kugel | funman: non-standard caches I believe |
| 15:50:08 | Torne | #define ARM946EJ-S or similar |
| 15:50:16 | funman | Torne: no, only V4 V5 and V6 |
| 15:50:22 | Torne | Well, then I think we should? :) |
| 15:50:28 | Torne | since that's sufficient to determine cp15 presence afaik |
| 15:50:42 | Torne | and it also determines dozens of other things |
| 15:50:42 | funman | what about ARM_CACHE_PRESENT ? |
| 15:50:50 | Torne | which we may not have a need for right now, but may be usefu lone day :) |
| 15:51:01 | Torne | is that an existing define? |
| 15:51:06 | TheSeven | funman: s5l8700/s5l8701 doesn't have a mmu |
| 15:51:10 | Torne | not all ARMs with caches have cp15, see portalplayer |
| 15:51:13 | n1s | there is a CPU_ARM7TDMI |
| 15:51:15 | Torne | they have weird external cache |
| 15:51:16 | n1s | define |
| 15:51:30 | Torne | Yeah.. do we not have more of those? |
| 15:51:33 | | Quit froggymana (Quit: CGI:IRC) |
| 15:51:40 | | Quit anewuser () |
| 15:51:50 | TheSeven | btw, why do we need to access cp15 at all? |
| 15:52:06 | n1s | Torne: i don't think so |
| 15:52:17 | funman | TheSeven: what's mmu-s5l8700.S for ? |
| 15:52:40 | TheSeven | only cache coherency stuff |
| 15:53:00 | kugel | TheSeven: fsr and far |
| 15:53:01 | TheSeven | it actually has a MPU |
| 15:53:06 | funman | Torne: hm or MMU_PRESENT ? this would make #ifdef simpler if we only check this information in system-arm.c |
| 15:53:33 | Torne | funman: Well, I would suggest that we define the specific CPU type in the target configs |
| 15:53:44 | Torne | and then use that to infer a bunch of other defines like MMU/cache/etc |
| 15:53:54 | Torne | and then use *those* to enable specific code |
| 15:54:04 | Torne | This is probably a reasonable amount of effort from where we are now though |
| 15:54:08 | Torne | but i think useful |
| 15:54:49 | Torne | funman: lemme find an example |
| 15:56:12 | amiconn | kugel: Hmm, that's really odd. Do you know whether it works on the beast using eabi? |

| 15:58:21 | funman | Torne: sounds good, perhaps in a new cpu_arm.h file |

| 15:58:52 | Torne | just ARM feature defines |
| 15:58:55 | kugel | "#if !defined(__CPU_ARM1136_ERRATUM_411920_FIXED)" :) |
| 15:58:59 | Torne | kugel: Yeah |
| 15:59:13 | Torne | If you get silicon that has a fix for the erratum you can define that to turn our workaround off |
| 15:59:18 | Torne | regaining whatever was lost by the workaround :) |
| 15:59:25 | Torne | see now this code is all open i can talk about it ;) |

| 16:13:28 | funman | ah, be is bigendian for meizum*, ysp3; nano2g is littleendian |
| 16:13:44 | TheSeven | afaik the 8700/8701 have an arm940tdmi |

| 16:14:33 | TheSeven | not yet |
| 16:14:36 | kugel | I thought both libs are auxillary utils for the build process. I can't remember anymore if I tried without -dev |

| 16:17:23 | funman | Torne: is there a difference between 't' and 'tdmi' suffixes? |
| 16:18:23 | kugel | just a shorthand I think |
| 16:18:40 | linuxstb | Doesn't each letter in tdmi mean something? |
| 16:18:46 | kugel | I don't think there's any t which doesn't support dmi as well |

| 16:22:01 | funman | Torne: I've compiled the list of ARM CPUs on FS #10296 |
| 16:22:33 | n1s | it appears to mean jtag basically |
| 16:22:46 | Torne | JTAG is a protocol, ICE is a thing to access over it :) |
| 16:25:46 | Torne | funman: 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 |
| 16:25:58 | amiconn | kugel: That call looks fishy. The new gcc version is a bit short to tell what it's actually trying to do |
| 16:26:00 | Torne | and some of htem mean something but aren't documented publicly :) |
| 16:26:24 | kugel | it also appeared fishy to me |
| 16:26:32 | amiconn | You can clearly see that either r0 or r1 must be wrong, because they're identical when calling mpeg2_idct_add() |
| 16:26:41 | funman | it appears only the arm7tdmi (PP, pnx0101, dsc25 SoCs) don't have those registers |
| 16:26:56 | kugel | compiling with -O0 would show how it expects the parameter passing, right? |
| 16:27:22 | amiconn | funman, Torne: There already is a macro for arm7tdmi specifically |
| 16:27:33 | Torne | amiconn: this isn't the only feature that should be conditional on chip type, though |
| 16:27:48 | Torne | amiconn: all the MMU/cache stuff should really be derived from ARM CPU type, not from target |
| 16:28:05 | Torne | at least where the target uses ARM's standard macrocells |
| 16:28:22 | Torne | which is also true of basically everything but PP |
| 16:29:34 | * | funman agrees and will let Torne do the work |

| 16:30:51 | Torne | funman: you can do it for 6 as well, it'll just be incomplete |
| 16:30:59 | funman | ranmachan: didn't test already, it'd be good if someone with an e200v2 tests it first |
| 16:31:06 | ranmachan | Sadly a bit cramped in there, would be nice to fit a connector... |
| 16:31:09 | Torne | just i suggest you make it print the whole FSR val instead of just those two fields |
| 16:31:26 | funman | although I could move the check after the known-to-be-working button check, i'm a bit lazy those days :) |

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

| 17:06:06 | kugel | maybe I should write to the gcc ml |
| 17:06:11 | kugel | that appears to be a bug |
| 17:07:10 | Torne | kugel: yes, sounds like it might be |
| 17:07:16 | Torne | kugel: however your argument for const params is wrong. |
| 17:07:26 | Torne | kugel: You still have to save r0-r3 |
| 17:07:43 | kugel | why? |
| 17:07:45 | Torne | calling them const only guarantees that the called function doesn't assign to those variable *names*, it says nothing about the registers |
| 17:07:51 | Torne | The function is still free to overwrite r0-r3 |
| 17:08:05 | Torne | The parameters don't necessarily stay in those registers. |
| 17:08:20 | kugel | good point |
| 17:08:23 | Torne | the const *only* protects you from accidentally assigning to the params when you meant to write something else |
| 17:08:29 | Torne | there is no difference in the generated asm, no optimisation benefit. |

| 17:10:06 | funman | perhaps I could enhance comments "no MPU/MMU" can refer to arm7tdmi or to !arm7tdmi in the context |
| 17:10:28 | Torne | funman: looks good, except don't print FAR for prefetch aborts |
| 17:10:33 | Torne | it's not updated |
| 17:10:50 | Torne | so it would just be the address of the last data abort, which is not useful ;) |
| 17:11:03 | funman | hm right |
| 17:11:25 | Torne | also you might consider for undef aborts, fetching the instructoin and printing that |
| 17:11:39 | Torne | (you know it's fetchable or you wouldn't get an undef) |
| 17:11:55 | Torne | it's not vital, though, i guess, you can find it in the elf binary |

| 17:33:36 | ThomasAH | ah, "Gentlemen, we have SOUND!" ... found a few |
| 17:33:43 | funman | ThomasAH: see http://www.rockbox.org/wiki/GentlemenMails |
| 17:33:58 | Unhelpful | Torne: ah, so the beast's CP15 may not have the ID code? |
| 17:34:08 | FlynDice | ThomasAH: I've been looking at the clocks setup for awhile now trying to sort things out but it's being rather finicky.... |
| 17:34:43 | Torne | Unhelpful: no, all ARMs with cp15 have the id register, but arm7tdmi does not have cp15 and thus no id register |
| 17:35:10 | amiconn | kugel: Is that only for this function, or all functions? |
| 17:35:21 | amiconn | In fact that looks like a gcc bug to me |
| 17:35:28 | funman | Torne: isn't cp15 mandatory & standardized on armv6 ? |
| 17:35:34 | Unhelpful | Torne: ...ah... i think my error was in thinking funman was replying to your <Torne> anyone know what ARM1136 revision the i.MX31 is? :) |
| 17:35:46 | kugel | it's possible that other functions are hit as well |
| 17:35:56 | funman | Unhelpful: but i was ! :) |
| 17:35:59 | ThomasAH | FlynDice: clock works fine for me after setting it on both sides in the correct order :) |
| 17:36:05 | amiconn | We could work around it by reordering the parameters of the idct_* functions. Of course that needs adjusting all asm implementations, not just arm |
| 17:36:13 | ThomasAH | FlynDice: or clocks as in ram speed and such? |
| 17:36:34 | kugel | I 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 |
| 17:36:49 | FlynDice | ThomasAH: er not the time but fclk, pcclk etc... |
| 17:36:51 | Unhelpful | kugel: what "strange" calling convention? |
| 17:37:00 | Torne | funman: yes.. we should do that, just not on arm7tdmi :) |
| 17:37:25 | amiconn | This *might* because the 2nd and 3rd parameters are pointers - gcc may consider them as (potential) 64 bit parameters, so r1 is skipped |
| 17:37:34 | kugel | Unhelpful: the gcc generated call appears to violate the standard calling convention |
| 17:37:49 | ThomasAH | FlynDice: this is for running without disabled caches I assume? |
| 17:38:03 | Unhelpful | amiconn: ...are pointers 64b on ARM? and since when? |
| 17:38:26 | amiconn | No - that's why I said it may be a gcc bug |
| 17:38:37 | kugel | amiconn: 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)? |
| 17:38:50 | amiconn | And also why I asked whether it's just this function, or all |
| 17:38:57 | Unhelpful | kugel: what if you cast the pointers to uint? |
| 17:39:06 | Unhelpful | (in the call) |
| 17:39:50 | FlynDice | ThomasAH: 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 |
| 17:39:58 | | Quit Strife89 (Ping timeout: 256 seconds) |
| 17:40:08 | FlynDice | make that as3525v2 |
| 17:40:19 | amiconn | kugel: And if it's more than just that one, be prepared to see spectacular crashes on various arm targets. Everywhere - not just in plugins |
| 17:40:47 | kugel | Unhelpful: same result |
| 17:41:28 | kugel | amiconn: I assume there's no crash as long as the called function is also compiled by gcc |
| 17:41:51 | ThomasAH | FlynDice: I'm not familiar with such details. fclk is like the FSB speed on PC hardware? |
| 17:42:03 | FlynDice | ThomasAH: That's wrong, FCLK is 120 MHZ PCLK is at 6 MHz |
| 17:42:08 | amiconn | Yes, but there are numerous asm functions in the core as well |
| 17:42:15 | amiconn | ...e.g. ata transfer |
| 17:42:45 | kugel | my hdd based yh925 behaved fine in the core |
| 17:43:04 | kugel | it appears to be dependant on the order of the parameters as well. swapping the 2nd and 4th one helps |
| 17:43:19 | kugel | (in the prototype only) |
| 17:43:40 | FlynDice | ThomasAH: and the bus is fastbus mode which means the processor is only clocked at 6 MHz right now |
| 17:45:17 | ThomasAH | FlynDice: thanks for the explanation, I probably have to read more about it |
| 17:45:28 | Torne | kugel: it definately sounds like an 8-byte-alignment issue |

| 17:45:40 | Torne | AAPCS requires that 8-byte values be passed in r0/r1 or r2/r3 |

| 17:48:48 | * | amiconn wonders whether this a general gcc-eabi bug, a gcc 4.4.3 bug, or a quirk in arm eabi |
| 17:49:04 | amiconn | What's the earliest gcc supporting eabi? |
| 17:49:28 | Torne | amiconn: the ABI is fine, but other than that I can't say :) |
| 17:49:39 | FlynDice | mt: I didn't need this until a few days ago but I think funman's clip+ needed it all along |
| 17:50:09 | funman | FlynDice: storage should be initialized after LCD, so i'm not sure if that's the problem |
| 17:50:21 | amiconn | Well, the reason why I am wondering is because two of those parameters are pointers, and two are ints |
| 17:50:43 | amiconn | In svn they are int/ptr/ptr/int, and that causes the strange gcc behaviour |
| 17:50:58 | Torne | well, the order should not matter |
| 17:51:02 | amiconn | I guess that both int/int/ptr/ptr and ptr/ptr/int/int would work fine |
| 17:51:03 | Torne | because the width of all those types is 4 |
| 17:51:22 | Torne | i can't see any reason in AAPCS why it should spill no matter the order |
| 17:51:27 | Torne | and have never seen this happen in other code |
| 17:51:43 | amiconn | So it's probably a gcc bug |
| 17:52:04 | Torne | yeah |

| 19:32:59 | kugel | yes |
| 19:33:21 | fml | Buschel: 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.

| 19:44:47 | funman | perhaps gcc assumes aligned on 64 bits means 64 bits |
| 19:45:27 | kugel | funman: what happens in the disassembly? |
| 19:45:36 | kugel | block is on stack, or in r3? |
| 19:45:47 | funman | just look if r1 is modified or not |
| 19:45:56 | kugel | I didn't compile it :) |
| 19:46:04 | funman | r0 is always 0 |
| 19:46:28 | funman | s.member goes into r1 for aligned(4) , into r2-r3 for aligned(8) - and thus leaves r1 untouched - |
| 19:46:32 | amiconn | funman: You're passing a pointer - and why should the pointer be aligned |
| 19:46:33 | amiconn | ? |
| 19:47:15 | TheSeven | S_a_i_n_t: I'm confused. The iLoader release you installed managed to boot /.rockbox/rockbox.ipod? I just found a bug that *must* have prevented this from working |
| 19:47:25 | funman | amiconn: DCTblock is "int16_t * ATTR_ALIGN(16)" in mpeg2_internal.h |
| 19:47:52 | amiconn | Yeah and? |
| 19:48:28 | amiconn | You're passing a pointer to it. That pointer is 32 bit. Alignment of its destination shouldn't matter at all |
| 19:49:31 | funman | I don't understand what you're asking me |
| 19:50:39 | funman | I don't know if alignement of the pointer is relevant for I don't know mpeg2dec code |
| 19:51:01 | kugel | volatile fixes your test case as well |
| 19:51:47 | amiconn | Eh, wait. The struct member is aligned? |
| 19:52:39 | amiconn | The block this member points to should be 16 byte aligned for performance reasons (cache line alignment, resp. alignment for line burst on coldfire) |
| 19:52:48 | amiconn | The pointer itself doesn't need to be aligned |

| 20:09:46 | amiconn | funman: Seems it was just a mistake when taking the buffer itself out of the struct. At least there is no explanation |
| 20:11:22 | funman | it it serves no purpose for optimization, just commit the change |
| 20:11:48 | kugel | funman: very good work on this find! |
| 20:12:30 | amiconn | It *may* have to do with dualcore on PP. I'll try it in a moment |
| 20:13:44 | * | kugel bets the underlying bug is as simple as "if (eabi && var_align >= 8) ..." instead of "if (eabi && var_size >= 8) ..." |
| 20:15:58 | pixelma | bluebroth3r: ok, in my RbUtil testing on PPC I had the wrong TTS set... the Utility doesn't hang with the correct one and "Test TTS" sounds correctly. But again the speex talk files are just noise, going to test my Ondio again |
| 20:16:52 | amiconn | Hmm. The decoder struct is dynamically allocated (as part of a larger struct) so that's pretty unlikely |
| 20:17:03 | pixelma | bluebroth3r: and I think RbUtil shouldn't freeze like that with the wrong TTS configuration |
| 20:17:11 | amiconn | The internal allocation mechanism only aligns to 32bit |

| 20:20:24 | | Quit planetbeing__ (Quit: planetbeing__) |
| 20:21:12 | amiconn | Another point is that even on PP libmpeg2 doesn't run dualcore itself. The core split is between video and audio |

| 20:22:25 | kugel | isn't libmad itself dual-core'ized as well? |

| 22:16:02 | endlesswonder | why no support for Classic v6? |
| 22:16:26 | AlexP | encryption has only just been broken, nobody has done the huge amount of reverse engineering work needed |
| 22:16:37 | endlesswonder | is there a tool for Classic to be able to navigate by the Folders you have the Songs on your PC? |
| 22:16:55 | AlexP | Don't know, but that isn't a Rockbox question |
| 22:17:18 | endlesswonder | doing a search for each single file is not all that intuitive nor quick |
| 22:17:38 | AlexP | I understand, but this is an on-topic channel :) |
| 22:17:42 | endlesswonder | esp. if you have a LOT of songs in different folders, that are not organized into albums by iTunes |
| 22:18:40 | endlesswonder | i mean come on now - just place my damn songs on the iPod as I originally had them on my PC! |
| 22:18:57 | endlesswonder | i went thru the meticulous time consuming effort to organize them via folers |

| 22:47:23 | amiconn | Bleh. For some reason eabi gcc doesn't build on opensolaris because 'patch' cannot find the files to patch?! |
| 22:47:56 | amiconn | The patch works the same way as the gcc patches for other toolchains, so I wonder why |
| 22:50:01 | kugel | amiconn: maybe it doesn't accept/handle -p1 ? |
| 22:50:14 | kugel | the eabi patch was made against 4.4.2 |
| 22:50:44 | amiconn | It does so for m68k, sh, and plain arm |
| 22:51:10 | kugel | maybe it still looks at the patch paths (it says gcc-4.4.2 in the diff) |

| 23:02:48 | Torne | kugel: the cache controller might know it |
| 23:03:21 | amiconn | I doubt it |
| 23:03:22 | Torne | but in general, no, ARMs have no way to know the address which caused the abort if they don't have an mmu/mpu |

| 23:06:04 | Torne | kugel: hm? |
| 23:06:25 | kugel | well could I hack something together if I know the reg where the address is in? |
| 23:06:35 | Torne | you could just dump theuser mode registers, sure |
| 23:06:46 | Torne | but i expect we either stack or overwrite several of them :) |
| 23:06:49 | Torne | otherwise you can't get to the handler |

| 23:10:57 | Torne | if you want to handle exceptions properly the thing to do is push all the user registers onto the abort mode stack and pass a pointer to UIE |
| 23:11:21 | amiconn | On the beast doom just crashes with eabi |

| 23:48:26 | kugel | data abort as soon as I select the difficulty (after executing the .wad). on my e200 it creases as soon as doom.rock launches |
| 23:48:34 | kugel | crashes* |
| 23:49:52 | amiconn | I think the reason is probably the same |
| 23:50:20 | amiconn | Data aborts might be disabled on the beast, so unaligned accesses don't crash, but they still give wrong results |

| 23:51:47 | Torne | Yes, if you disable alignment aborts it does them properly, with multiple cache accesses |
| 23:52:04 | amiconn | Ah, hmm |
| 23:52:12 | Torne | we shouldn't disbale alignment aborts, though ;) |
| 23:52:20 | Torne | since it's still slower |
| 23:52:25 | Torne | and code that works that way won't work on other chips |
| 23:52:42 | amiconn | On earlier arms which allow disabling that check, unaligned accesses work, but not the way one would expect |
| 23:52:52 | Torne | Yes, they rotate the aligned word |
| 23:52:58 | Torne | but armv6 and later do it properly |
