#rockbox log for 2014-01-02

00:36:20[Saint]lebellium: sad to say thats probably due to only one touch target having FM, and no one caring about that target in the slightest except for when it stops building.
00:36:27[Saint](D2)
00:37:26lebelliumyeah... but now there is the YP-R1 too, it's time to care, I want the theme engine to work for touchtargets too :P
00:37:46[Saint]It should be trivial to add FM seek/skip tags.
00:38:06[Saint]But I'm somewhat busy getting drunk today.
00:38:38lebelliumwe can talk again tomorrow :)
00:40:41JdGordonlebellium: whatcha wantt?
00:40:47lebelliumah!
00:40:52lebelliumI have much work for you JdGordon :D
00:43:48lebelliumJdGordon: touchscreen tags, FMS:
00:43:49lebellium-ffwd and rwd, I had to use prev and next again, with repeat_press. But it seems that there is no auto-tune that way. It stops seeking when I release the finger
00:43:51lebellium-play: music playback in the FMS -_- and "mute" is different from pausing the FM radio
00:43:52lebellium-the progressbar (frequencies) can't be moved with the finger
00:44:08lebelliumffwd and rwd don't work*
00:44:25lebellium-"menu" opens the context menu instead of going back to the main menu as in WPS
00:44:48lebellium-"contextmenu" doesn't work
00:45:55*JdGordon suggests digging up apps/gui/skin_engine/skin_touchsupport.c
00:46:08JdGordonyes, it isnt setup for the radio at all
00:47:03lebelliumI'm the 1st one to use FM radio on a touchscreen target? Well, nothing should surprise me anymore in Rockbox...
00:48:02[Saint]No. Youre forgetting we have two input systems.

00:48:16[Saint]Grid and absolute point.
00:48:20lebelliumyou mean the grid?
00:48:22lebelliumyes
00:48:52[Saint]And the cowon has HW keys anyway iirc.
00:49:02lebelliumgrid is just a workaround for lazy guys who don't want to make a real touch theme
00:49:21[Saint]no. it predates it entirely.

07:20:28flatr0ze_Hello. Got a QQ: how come we can't use RSRC firmware for BCM2722 chip off the official Apple firmware for iPod Video with rockbox? If we figure out the API of that firmware, can't we just "pipe" the raw bits of mpeg4 files to that firmware, getting the picture out?
07:30:52[Saint]I don't believe anyone is stopping you from doing so.
07:34:37man_in_s1acki would if i could be bothered :P

07:38:47[Saint]If one managed to reverse the firmware, though, there would be absolutely no point in running a shim to drive that firmware to drive the videocore chipset when you coild just poke the HW directly.
07:39:48[Saint]Its many hundreds of man hours for very little gain though, really.
07:51:03man_in_shacki prefer woman hours really

07:58:54JdGordon[7]: hey, what do we know aout the 5gnano?
08:00
08:08:56[Saint]http://www.freemyipod.org/wiki/Nano_5G
08:09:59[Saint]or "very little", apparently.
08:12:17[Saint]in the hw section there you can see the similarity between the nano3g and classic i mentioned in *-community
08:13:18[Saint]for some odd reason they're kinda expensive when you can find them though.
08:14:58 Join ender` [0] (krneki@foo.eternallybored.org)
08:23:34flatr0ze_is 1 man hour == 1 woman hour?
08:32:11[Saint]the man in man hours refers to the kind, not the sex, so - yes.
08:45:31man_in_shackif shuffle is on, do repeat modes do anything?
08:48:17***No seen item changed, no save performed.
08:54:41man_in_shacki.e., if i have repeat = none and shuffle = on, will rockbox stop playing after all songs have played?
08:54:48man_in_shackor is the "next track" fully random?
09:00
09:13:35[Saint]repeat mode should win in that instance.
09:14:30[Saint]and playback is never fully random.
09:14:43[Saint]even when shuffled, but that's an aside.
09:15:16[Saint]true random shuffle is often undesirable.
09:16:36man_in_shackso if i have repeat = none and shuffle = on, no song will play twice, correct?
09:17:11[Saint]we have a psuedo-random shuffle. Each track is played exactly once and once only. The user can control the frequency of more desirable tracks/albums by increasing their frequency in the playlist.
09:17:15[Saint]and no.
09:17:26[Saint]no track will ever play twice.
09:17:39[Saint]unless it is in the playlist twice. or more.
09:17:45man_in_shackunderstood :)
09:18:42[Saint](or the repeat mode == shuffle, which will play all tracks once in playlist order then reshuffle and restart the playlist)
09:19:16man_in_shackyes, i get that, but i was asking about repeat = non :)
09:20:41man_in_shackany themebuilders here use linux systems?
09:21:45[Saint]there's nothing linux-specific i could think of in reference to theme building.

09:23:18man_in_shackbecause something's funky with my libs or something and the simulator doesn't display 1bit bmps
09:24:00man_in_shackalso the files don't seem to have the correct headers. "$ file mybmp.bmp" says "data" instead of "Windows Bitmap image" or whatever

10:48:54SovonHalderI had to hold menu+pause button to restart my iPod

11:29:04SovonHalderI admit I am a total tech n00b..so i have a question..Can I please know HOW serious is this issue of mine?
11:32:17lebelliumyou should first learn how to be patient. kugel told you he's looking at it, that may take more than a few seconds ;)
11:32:55wodzkugel: What do you think about integrating buflib state integrity check? The cost is not that high: 1) +1 buflib_data in cookie to store crc 2) crc calc of first 3 buflib_data elements in cookie on alloc and shrink 4) check of crc in block_move() to assure integrity. crc routine is already present in core.
11:33:54kugelperhaps in DEBUG builds?
11:34:56kugelbut yea, cost is pretty minor, seems like a good idea
11:36:17kugellow enough to enable it for all builds I'd say
11:36:48wodzkugel: I'll clean it up a bit and push it to gerrit
11:42:19kugelfor DEBUG builds we might want to consider crc check in buflib_get_data()
11:43:34wodzkugel: I thought about checking whole buflib state on context switch in DEBUG (just as we check for stack ovl)
11:43:52wodzI couldn't get it to work for sdl threads though
11:44:45man_in_shackso i'm just installing wine now and i'm going to see if irfanview can do bmps that don't splode
11:45:06kugelman_in_shack: have you checked latest rockbox git master?
11:45:21kugeltold you there was a fix for gimp bmps recently
11:50:04man_in_shackyeah, but i want to keep my sansa on stable releases
11:50:49lebelliumThen wait for 3.14, it should come out soon
11:51:10man_in_shackdefine "soon"
11:51:13man_in_shack(:
11:52:05wodzsoon as when we do the release :-)
11:52:13man_in_shackthat's what i thought
11:52:47lebelliumI don't know if the delay is due to a lack of time or lack of motivation
11:52:58lebelliumbut hopefully it gets released in January :)
11:53:25man_in_shackmaybe it's a lack of lacks

12:14:09kugelthe only reason we do it currently is because the font engine keeps the files open
12:14:30man_in_shackkugel: where do i find the built-in icons in the source?
12:14:48kugelwodz: for some it isnt that rare, plus it really looks like something is wrong (even if intended)
12:15:46lebelliumwodz: yes it's reproducible in the sim
12:16:03wodzkugel: we should get usb screen skinnable, handle it theme and problem fixed :-)
12:16:26kugelthe problem that fonts have to be closed remains
12:16:33man_in_shackuisimulator/common/player_icons?
12:16:36lebelliumthere is no difference with before: the USB screen still loads my SBS (status bar and backdrop).
12:18:16*man_in_shack sighs
12:19:07kugellebellium: this is clearly not what the code intends
12:21:16kugelwodz: I dont think we need a separate usb skin, it's not at all interactive. perhaps just a way to specify a different usb icon
12:21:48kugelin the meantime we should just show the base skin with list replaced by the usb icon (cropeed if necessary)
12:22:44lebelliumkugel: I thought the code fix was to unload the theme during USB connection?
12:23:12[Saint]oh, yay, lebellium dusted off this old chestnut.
12:23:35kugellebellium: no, it should be doing this for longer. the recent fix was to also really unload the backdrops of the themes
12:23:45lebelliumok
12:23:52kugel(it did unload the backdrop but did not free the buffer for it)
12:23:52lebelliumso actually it does nothing
12:23:56lebelliumnothing works :)
12:24:14lebelliumit loads my full SBS including backdrop
12:25:03[Saint]I recall he and I discussing that reality didn't match what the code intended and the sbs remained, sometimes somewhat butchered, in the USB screen.
12:25:28wodzkugel: with skinned usb screen simple animation would be possible for example
12:26:03[Saint]I think back then we may have dismissed it as us pushing the skin engine to do weird things.
12:26:26kugelwodz: right. anyway it won't fix the root cause :)
12:27:55[Saint]something handy about that might be properly handling a "safe to eject" mesage.
12:28:13[Saint]But I'm not how how reliably that can be detected.
12:29:25[Saint](or any method to detect this at all, presently? I forget)
12:30:57wodzI'd expect it to be some special ums packet to signal the storage that host finished operation and synced buffer
12:31:04[Saint]I understand a complete lack of "its ok to unplug me now" may be disconcerting to some people.
12:32:02wodzbut I don't know ums much
12:33:40pamaurysafe eject doesn't exist in UMS
12:33:57pamauryit's only an OS thing about flushing the caches
12:34:04bertrikI think there is indeed a SCSI command that is usually used to indicate that the host is done with it
12:34:14bertrikSTART/STOP_UNIT if I remember correctly
12:34:54kugelI think we already implemented something like this?
12:35:17kugelwere you could press a button to transition to charging only once you unmounted on the host
12:35:38kugel(it didnt work properly on some OSs)
12:35:42bertrikI don't remember seeing support for it in rockbox, if needed at all
12:36:34pamauryI'm not sure hosts actually send this command at all, or at a useful time
12:37:29pamauryone would need a try to be sure
12:37:45bertrikI think it is sent on "safe removal" on the host
12:38:11bertrikusb_storage.c handles it but only sets a flag internalyl
12:38:28pamauryit's actually more complex than just start/stop, the host can specify the power condition: active, idle or handle per logical unit

12:40:17pamaurybut what do you want to use it for exactly ?
12:41:37wodzI think if the device introduce itself as auto-removable then host sends this sequence to inform device it is ready. It is common practice in usb sticks to do so.
12:42:23wodzIf thats is the case the device disappears after 'safe remove'/eject
12:43:22[Saint]if at all possible, some visible indication of this state to the user would be nice.
12:43:55[Saint]non-essential, the last decade says so, bit nice.

13:05:29man_in_shackso i've just about finished wps
13:05:48man_in_shackbut i'm a little confused about what sbs is
13:06:34lebelliumsbs = menus
13:06:40lebelliumfms = FM radio
13:06:48wodzmost probably because sbs is a bit confusing :-)
13:06:55lebelliumsbs is not confusing!
13:07:08wodzsbs is abbreviation for skinnable status bar
13:07:18man_in_shackah ok
13:07:37wodzthe twist is that it doesn't have to be status bar per se
13:07:49lebelliumI didn't know that wodz, thanks, and I made more than 10 themes without knowing it. So it's not confusing :P
13:07:56man_in_shackfun
13:09:29wodzlebellium: Maybe it is confusing for me because I know what it was before. You know, you can do something if you don't know it is impossible :-)
13:09:52man_in_shackthe docs aren't really clear on how to design sbs
13:10:01man_in_shackwhat is "info viewport" exactly?
13:10:45lebelliumman_in_shack: just look at a theme with SBS, it's easier to understand. Mines have. But there are complex themes^^

13:13:36[Saint]status bar skin, fwiw, iirc.
13:15:12[Saint]either that, or skinnable base screen.
13:15:24[Saint]i forget. that was some time ago now.
13:15:51[Saint]i think the latter.
13:16:14man_in_shacksoft boobie skin
13:16:26[Saint]as its more obvious then that a status bar needn't necessarily be involved.
13:17:33man_in_shackright
13:20:28wodzgevaerts: You volunteered to implement volume limiter - could you review g#697 ?

13:22:10pamauryI think I found one of the worst workaround ever in Freescale SDK
13:23:23wodzdon't be shy - share the finding
13:23:32pamauryPartition offset in MBR are incremented by 4 except if the underlying media is MMC or if the chip uses ROM revision >TA4
13:23:56pamauryand only for some partition kinds
13:24:11wodzwhy it is so?
13:25:05 Join Scall [0] (~chat@unaffiliated/scall)
13:25:18pamaurygiven the code, I think they introduced a difference between MMC and SD by mistake in some ROM because of code duplication, so then they introduced a software workaround and finally fixed it in some later ROM ?

13:31:31[Saint]i guess i should comment on gerrit, but:
13:31:52pamaurywodz: ok I see, the hifietma8 uses the id 85 but it should have introduced a name in scramble in the first place !
13:32:17[Saint]that volume limiter looks like it silently breaks the users expectation of the current volume displayed.
13:32:44wodz[Saint]: why?
13:33:37[Saint]the volume level displayed is going to be normal, when the volume is really capped.
13:34:21wodz[Saint]: no, it is not AFAIK. There is other problem however
13:34:26[Saint]mind you...precut does that now already.
13:35:08fs-bluebotBuild Server message: 3New build round started. Revision 9dbdec1, 243 builds, 32 clients.
13:35:51[Saint]a quick look from a slightly drunk me and it seems like it will let the user set a volume (and skins display that value) but silently cap it at a set value.
13:36:25[Saint]if I'm wrong, apologies.
13:36:53lorenzo92kugel: ping
13:37:18kugellorenzo92: pong
13:37:18wodz[Saint]: Ah, now I see. You are right
13:37:47wodzI thought it modifies original passed value as well but it does not
13:37:48[Saint]Something I dislike very much about precut.
13:37:50lorenzo92kugel: did you have a look at my patch?
13:37:53fs-bluebotBuild Server message: 3Build round completed after 165 seconds.
13:38:07[Saint]Thats on my "get round to it eventually" list too.
13:38:16kugellorenzo92: not yet
13:41:30[Saint]I believe gevaerts had some idea for a way to implement volume limiting that worked nicely. Or maybe he had the idea that he might have an idea in the future if no one else did. :)
13:41:40pamaurywodz: I feel stupid now, I pushed the patch but it is wrong: 92 is also used by ihifi760
13:42:11pamaurythat's enough proof to me that the rk27 targets should be placed in the list or don't bother with modelnum conflicts, otherwise a mistake is easily made
13:42:25[Saint]next up: triple digit build identifiers. :)
13:43:00lorenzo92by the way, who actually uses this target id? the bootloader? perhaps rb util?
13:44:45lebelliumihifi760 has no wiki pages, has it? There is no information about that target and how to install rockbox to it. That's a pity.
13:45:57[Saint]wodz: I'll make my opinion known on gerrit some time tomorrow.
13:46:24[Saint]I have had degreasing amounts of time for Rockbox stuff lately.
13:47:13pamaurylorenzo92: bootloader/rolo for checksum'ing
13:47:16[Saint]The time I do get is usually spent on the forums these days. I haven't looked over gerrit in a while.
13:47:19kugellebellium: I think pamaury and wodz are a bit lazy with keeping the wiki up to date
13:47:36[Saint]Which is a shame as theres a lot of good stuff on there.
13:47:46lebelliumthere is no problem with pamaury. All Creative and Sony targets have a wiki page
13:48:07lorenzo92kugel: that's lebellium's job, isn't it? :P
13:48:17kugelI failed to find information about Sony's few weeks ago
13:48:28wodzkugel: audiophile daps are not my field of interest :-)
13:48:28pamaurykugel: like ?
13:48:34[Saint]I think the problem is zero obligation to update the wiki.
13:48:58wodzkugel: It is mortalis work
13:49:02pamauryI try to keep the wiki up to date but if I missed something I'll be pleased to add it
13:49:05lorenzo92Saint: haha I agree.
13:49:50 Quit Scall (Quit: Bye bye)
13:50:00kugelpamaury: it looks like i failed
13:50:14lebelliumAFAIK the ihifi760 is the only recent target with absolutely no information about it. I thought it was commonly admited that every target should have a wiki page, even if that pages countains 2 lines or is outdated. What's the point of having a ihifi760 Rockbox build if we don't even know how to install the bootloader...
13:50:52[Saint]we may not necessarily want it known.
13:51:02pamauryall my targets have a at least one page: the description page
13:51:04[Saint]early development, brick risk, etc.
13:51:14pamauryand if there is code in the repo, then there is a second page for the Port
13:51:29[Saint]there are times when it may not be prudent to publish all info, i mean.
13:51:30lebelliumyes, your wiki pages are really well documented pamaury, very helpful
13:51:32pamauryI admit I fail to update TargetStatus and some other pages at time
13:52:36lebellium[Saint]: sure but is that the reason in the particular ihifi case? I'm not sure. I just think mortalis forgot it/doesn't care/is lazy :)
13:53:27[Saint]Oh. I have no idea. Just speculating on reasons why we may have execution on a device without any wiki documentation.
13:53:44kugelpamaury: sorry then
13:55:23pamauryno problem :)
13:56:33lebelliumeven if we don't publish install instructions immediately (early developement, brick risk etc as you said), there should be a wiki page with basic hardware information at least. Commiting rockbox code for a new target with 0 information about it sounds really strange to me
13:57:07lorenzo92absolutely, even if code has to be a source of information
13:58:56[Saint]well...I guess at some point the "its a wiki" argument has to come up.
13:59:47[Saint]If you're crap at writing docs, leave it for someone who cares enough for them to be there. Community project and all.
14:00
14:00:19bertrikMaybe it's very similar to another target?
14:01:19lebellium"it's a wiki, do it yourself if you're not happy" is not a valid argument either in that case. I don't know the Ihifi760 and I'm not a dev. I can update the status summary pages and typos but the guy who writes or commit the rockbox code for a new target should write the wiki page first. Then other people may edit and improve the page if needed
14:01:24[Saint]Give it to the RSB for something for them to do. "Agenda: New targets to include basic wiki documentation?".
14:01:37[Saint]They'll be happy for something to do.
14:01:47*[Saint] bets not really
14:02:15pamaurywiki doc is up to the maintainer, at least for a start because he is the one who knows
14:03:06[Saint]right. but its more an unwritten rule. than a rule rule.
14:03:32lebelliumI expect any usual Rockbox dev to know the unwritten rules
14:04:10lebelliummortalis is not an unknown newbie.
14:04:56[Saint]right. but what I'm saying is, known or not, it isn't enforced. at all.

15:00:59[Saint]there's no concept of layers in skins past backdrop and foreground. you *can* layer viewports, and they are drawn in parsed order, but to guarantee the draw order the content must be static.

Its position inside a viewport is limited to things like left/center/right... you can do that conditionally... now, if you mean "position viewports" at different points depending on conditions, I think a given viewport has fixed coordinates, but you can display different viewports conditionally, or conditionally set the fixed coordinates.... wha

17:22:15man_in_shackyay
17:22:51copperbut it's not acceptable to assume users installed the *extra* font pack
17:23:06copperyou have to say what font your theme needs, in the theme description
17:25:58lebelliumor just say that the font pack is needed
17:26:09man_in_shackright
17:26:29man_in_shacki mean the thing in rockbox utility that says "additional fonts"
17:40:50toehser1I think those are the ones that are in http://download.rockbox.org/release/3.13/rockbox-fonts-3.13.zip which are the ones that the validation won't let you include with a theme. I agree it is a nice thing to include in your description "requires font pack" or "requires xxx.fnt". But, it isn't possible to actually just bundle one of these with your theme - so, de facto, it is sort of assumed...
17:41:56toehser1I've discovered that all the fonts I _like_ aren't in there, anyway, so I just bundle them...

23:12:30saratogain an ASM block, i know that gcc can stack registers that are already in use automatically
23:12:45saratogadoes this also apply to special registers like the link register or do I have to manually stack those?
23:13:16derfI... don't know, actually.
23:13:25derfTry it and find out.
23:14:01derf(for example gcc does this correctly for %rbx on x86-64, but not %ebx on x86-32)
23:15:44pamaurysaratoga: I could say "look at the doc", but that would be a joke actually ;)
23:15:56saratogaalready testing it
23:18:50derfI mean, I would hope that gcc stacks lr already if it stacks anything at all.
23:19:08saratogaindeed it does
23:20:00saratogainterestingly pop(r4,....); bx lr becomes pop{r4,..., pc}
23:20:02saratogawithout hte bx
23:20:15saratogabut i guess popping the LR to the PC does the same thing
23:20:50derfRight, that is why I was hoping it would always stack lr.
23:20:59saratoganext question: if list the stack pointer as a clobber, does it store the stack pointer or just trash the stack?
23:21:04derfIt gets you a free return from the stack restore.
23:21:06kugelgcc of course stacks everything as required by the calling convention
23:21:58derfsaratoga: Uh... that sounds like it almost certainly wouldn't do what you want.
23:22:09kugelunless you make the function naked as well
23:22:13derfWhere can it store the stack pointer?
23:23:09saratogaderf: couldn't it store the stack pointer as a constant at the end of the asm block?
23:23:22derfAs a constant?!
23:23:23kugelyea, only option would be a pc-relative location
23:23:39saratogawe do that in various asm functions
23:23:45 Quit PurlingNayuki (Ping timeout: 272 seconds)
23:24:00derfWell, that may work okay for Rockbox, but it means your code is not re-entrant.
23:24:00saratogaalthough the pc relative thing might be a problem
23:24:21derfWhich is kind of a problem in lots of other contexts.
23:24:27saratogayou mean from a context switch?
23:24:29derfCertainly not something I'd expect gcc to do automatically.
23:24:43derfYes... two threads calling the same function.
23:24:52saratogahmm good point
23:25:03kugelre-purposing sp is generally a bad idea
23:25:21kugelon hosted platforms it can also conflict with signal handling
23:25:27saratogaso is only having 14 general purpose registers not counting SP
23:25:28derfYeah.
23:25:35kugeland on others with interrupts
23:26:07kugeli once fixed rockbox code to not re-use sp to make it work on hosted
23:26:22derfI was assuming by "clobber" you meant you were adding more things to the stack yourself. Changing to be not a stack pointer entirely is a bad idea.
23:26:24saratogayeah i know libmad does that
23:26:36kugelnot anymore i think :)

23:27:03saratogawell knowing i can use the LR is nice, i had always assumed i couldn't
23:27:16saratogain an asm() call anyway
23:28:06saratogai'll add this to the wiki
23:28:43kugelre-using LR can also be problematic in some sitations, but not as problematic as with sp
23:30:17saratogaanything i should keep in mind?
23:30:45kugelimagine a IRQ/signal handler wants to examine the call stack of a normal thread, and it occured during such an asm block
23:31:24derfNah, this is normal for ARM.
23:31:39derfI think there are some hints you can provide to tell it about stack unwinding.
23:31:55derfBut honestly I've never looked into it.
23:31:56kugelsaratoga: just dont use sp
23:32:05 Join sakax [0] (~sakax@unaffiliated/sakax)
23:32:12saratogayou'd only ever do that if theres a data abort or prefetch error right?
23:32:12saratogaok
23:32:24kugelright
23:32:34derfWell, we use this for profiling on B2G, for example.
23:33:09derf(using libunwind)
23:33:20kugelbut you can also travel the call stack by only looking at the stack iiuc so it's a non-issue probably
23:33:28derfRight.
23:34:37kugelmight interfere with __builtin_return_address(0) ?
