01:00:01*amiconn wonders how un-inlining functions would significantly change stack usage
01:00:16Mikachuamiconn: the function is recursive
01:00:25amiconnand?
01:00:46amiconnInlined or not - each call will allocate a stack segment
01:00:51Mikachuit allocated 512 bytes on the stack every recursion befoer
01:00:57Mikachunow it does that in a separate function
01:01:12 Join toffe82 [0] (n=chatzill@adsl-75-3-221-137.dsl.frs2ca.sbcglobal.net)
01:01:14Mikachuthat memory was only used before the recursive call anyway
01:01:22amiconnThat's still the same stack
01:01:51Mikachuno, the 512 bytes are popped when the (new) separate function returns
01:01:54 Quit cg_ (Read error: 60 (Operation timed out))
01:02:04Mikachuit used to be push 512 bytes -> call self -> push 512 bytes -> etc
01:02:20amiconnYes, and I would expect gcc to free this space as well if the function is inlined
01:02:23Mikachunow it is call new -> push and pop 512 bytes -> call self -> etc
01:02:23bertrikI can imagine saving memory by reusing the same path buffer (appending and truncating it as you go deeper or shallower)
01:02:48Mikachuamiconn: the recursing function isn't inlined, the one that pushes 512 bytes to the stack is

01:03:58KittenKatso i was wondering, has anyone had any luck getting the C200 usb to actually mount under linux?
01:04:25amiconnIf a function gets inlined, its contents basically become a block (at least that's how I understand it). And since the inlined function's variables are declared in that block, the space should be freed again when the function (i.e. the inlined block) ends
01:04:38Mikachuamiconn: it didn't end before it calls itself though
01:04:59amiconnThe *inlined* function does end before the containing function calls itself
01:05:21KittenKatshows up as [265556.612314] generic-usb 0003:0781:7450.0006: input,hidraw0: USB HID v1.10 Device [Rockbox.org Rockbox media player] on usb-0000:00:1d.7-1/input1 in dmesg but wont mount. does charge thou
01:05:31Mikachuright, okay
01:05:46Mikachui agree it is pretty silly of gcc if it helps to uninline it now that i think about it :)
01:05:58gevaertsKittenKat: ubuntu 9.04?
01:06:00Mikachui was caught up on the fact that the same commit split out the allocation to a new function
01:06:01LloreanKittenKat: Ubuntu or an ubuntu derived distro?
01:06:19amiconnInlining shouldn't change stack usage (apart from the return address on targets which have no link register, and stack args)
01:06:22KittenKatubuntu derived distro
01:06:22KittenKatalso fails under debian
01:06:22KittenKatand slackware
01:06:34amiconnIf it does, I'd consider that a major gcc bug
01:06:39KittenKatno windows boxes to try it on
01:06:54gevaertsKittenKat: are you running hal?
01:07:16KittenKatyup
01:07:32gevaertsok. Most probably this gphoto2 bug then...
01:07:33amiconnThe new function makes sense, the explicit __attribute__ ((noinline)) doesn't, afaiu
01:07:49KittenKatdidnt auto or manual mount, i tried every variation of the mountpoint

01:17:48JdGordon|amiconn: the buttonbar... am I going to get strife if it gets removed?
01:18:02 Quit notlistening ("Leaving")
01:18:11amiconnyes
01:19:08JdGordon|arg... why?
01:19:42amiconnAhem, it is an established and helpful feature of rockbox?
01:20:01amiconnImo viewports should make it significantly easier to implement the button bar, even using the user font (i.e. variable height)
01:20:35LloreanWe don't exactly go out of our way to display what any other button does from screen to screen. Why do those buttons need a special case? In most screens the button use doesn't correspond directly with the label anyway, except WPS.
01:21:20amiconnThose buttons have *no* labels, and are meant to change meaning. Other buttons are usually close in function to their labels
01:22:12JdGordon|amiconn: if they were *always* disaplayed then that would make things much easier
01:22:16JdGordon|but they arnt...
01:22:52amiconnWhy would that make things easier?
01:22:55Lloreanamiconn: "A-B", the Windows button on Beasts, the "lines and stuff" submenu button on e200, etc, all have more or less functions we've just decided on.

01:25:25JdGordon|I would be very happy to force them always on the screen if they are enabled
01:25:34amiconn?

01:26:12HillshumWouldn't this solve the support issue with configurable buttons?
01:26:28LloreanHillshum: What?
01:26:34LloreanThis has nothing to do with configurable buttons.
01:26:49amiconnThe choice is there so people who know the functions (or are willing to do some guessing) and want the extra space can disable them. The display on those targets isn't exactly large
01:27:04pixelmaalso - no, thinking about blind users etc.
01:27:09Lloreanamiconn: So why not just expect people to learn what they do like any other buttons?
01:27:25LloreanWe have plenty of buttons with ambiguous uses on many screens.
01:27:30amiconnWhy give up a feature that is already there, and can be kept easily?
01:27:51rasherpixelma: surely whether or not the button bar is there is completely irrelevant to blind users?
01:27:52amiconn...and which makes sense?
01:28:02Lloreanamiconn: Are you doing the work to keep it around after the rework?
01:28:10 Quit dmb (Read error: 113 (No route to host))
01:28:16amiconnWhy rework things which work?
01:28:20HillshumBut if a way was there to show whatever each button does, then could we allow users to configure the buttons because they would be able to figure them out easy?
01:28:27Lloreanamiconn: Did you read JdGordon's email?
01:28:50LloreanHillshum: It doesn't show what every button does. It's a specific feature for three buttons on a specific target.
01:28:59amiconnLlorean: Other buttons aren't aligned in a way that allows easy display of their function.
01:29:23pixelmarasher: that was in response to Hillshum's "idea". Besides the fact that you can't display the button mapping of other targets where the buttons are physically layed ouit differently
01:29:31Lloreanamiconn: My point is more "people have shown a marked ability to actually learn how to control their devices, three more buttons isn't going to break them"

01:33:02amiconnImo that deserves a clear *no*.
01:33:36rasherSo in this case we do want to mimick the OF?

01:34:29amiconnrasher: No, we do want to use the hardware like it's designed (the cases where we can do that are rare enough...)
01:35:00amiconnWhy would the button bar be not part of the ui? It clearly is a logical part of the ui...
01:35:22LloreanThe graphical button bar and the physical buttons are two different things
01:35:28LloreanThe physical buttons are still a part of the UI either way.
01:35:46LloreanYou yourself even mentioned the button bar is expected to be turned off once the user learns the functions, to reclaim the limited screen space
01:35:55amiconnThe button bar shows what functions the softkeys has *in this screen*, so it's clearly related
01:36:10amiconns/has/have/
01:36:32amiconnLlorean: It's not *expected*, it's a choice
01:36:48LloreanSo why doesn't he get list viewports working, and then if the button bar is important enough, you can reimplement it within the new code?
01:37:11LloreanThis is one of those situations where we're holding everyone back for a *visual effect* that's only useful on, basically, one target.
01:37:34amiconnIt's not one target, it's three. And there are more potential targets
01:37:39Hillshumvisual effect plus ease-of-use
01:37:49rasherIt's a limited amount of users.
01:37:52 Join JdGordon| [0] (i=4600bada@rockbox/developer/JdGordon)
01:37:52Lloreanamiconn: How many of these targets have the buttons positioned properly, as you mentioned?
01:38:23amiconnAnd if you're talking about visual effects - viewported lists are much more *only* visual effect than the button bar is
01:38:29LloreanAnd what are these three targets? I thought it was just the Recorder line?
01:38:40amiconnYes, and there are three recorders
01:38:55*Hillshum isn't sure if that counts as three targets
01:39:04JdGordon|the BB could be usable on a few more targets, but not perfect like on the recs
01:39:06amiconnE.g. the AV3xx also has buttons like this (although to the right instead at the bottom)
01:39:10LloreanWe still consider the iPod 5G "one target" when it needs two different builds.
01:39:18LloreanAnd the AV3xxx is not a realistic future target at this point, is it?
01:39:47amiconnAs I see it, the button bar and a touchscreen ui are somewhat similar
01:39:49rasherAnd having it to the right just means it's not really going to be the same thing at all
01:40:23Lloreanamiconn: So reimplement the button bar using the touchscreen stuff after the change then?
01:40:25KittenKatso, there is a build for the 5g at somepoint in the distant future?
01:40:33LloreanKittenKat: 5G what?
01:40:40amiconnWith viewports it shouldn't matter. Left, right, top, bottm - just a matter of viewport allocation. Same for the number of softkeys
01:41:32amiconnLlorean: Huh? I'm not saying that our current touchscreen stuff works like this, but I can imagine a button bar with touchable buttons for some screens. Vkeyboard would be one example
01:41:35pixelmasomeone mentioned those new Samsung port devices have two buttons below the screen - also the H10 and the Beast though. And it was an idea to make the button bar useful on touchscreen targets
01:42:08KittenKatipod
01:42:26Lloreanamiconn: That doesn't mean it's the same case as the button bar, then, though. The vkeyboard isn't going to be displaying alongside the list.
01:42:34LloreanKittenKat: The iPod Video has been supported for ages.
01:42:36amiconnAnd?
01:43:00Lloreanamiconn: So their "similarity" is what, exactly, other than possibly looking similar?
01:43:01amiconnThat was just one example - of course a touchable button bar could work in other screens too
01:43:32JdGordon|<amiconn> Why would the button bar be not part of the ui? It clearly is a logical part of the ui...<- because the ui area might not be exactly at the bottom of the display
01:43:48amiconnUh, why that?
01:43:56LloreanThere's not a touchable button bar for touchscreen targets, and having used one, I don't find a particular need. Touchable buttons within the WPS (and, if the WPS can be showed alongside the list, the ability to continue using them) would cover it just fine.
01:44:00JdGordon|because it will be up to the user
01:44:06KittenKatLlorean i thought the ipod video is 4g
01:44:17KittenKatthe new 120gb ipods are 5g no?
01:44:24LloreanKittenKat: No, the 4G is the iPod 4G. Then there's the iPod Color/Photo which is a variant of the 4G with color screen.

01:44:58KittenKatwhy not?
01:45:12LloreanBecause the people who have them aren't doing the work.
01:45:16*amiconn is definitely against giving up functionality for cosmetics
01:45:16HillshumLlorean: 120gb is actually 7th gen

01:45:31KittenKat*nods*
01:45:40LloreanHillshum: Oh really? They use different firmware and have different hardware beyond the HD?
01:46:13HillshumLlorean: Sorry, I was just assuming
01:46:13JdGordon|amiconn: its really unfair to bassically kill a nice feature for the other 25 targets for a single target which has a userbase of 6
01:46:14Lloreanamiconn: But we're not giving up functionality for cosmetics. We're giving up cosmetics for other cosmetics.
01:46:31LloreanHillshum: Please, PLEASE don't make random assumptions like that in here. People read these logs and repeat them elsewhere.
01:46:34JdGordon|amiconn: which is why im happy to force the bar always on or always off instead
01:46:38amiconnThe button bar is not just cosmetics
01:47:25Lloreanamiconn: As much as what list viewports can become will be.
01:47:26amiconnIt's an aid for beginners, and for those who easily forget things. But for others it's taking up precious screen space, hence the option
01:47:44amiconnAnd I still don't know what's problematic about that
01:47:52*JdGordon| questions if htere is such a thing as begginiers to the ajbr's anymore
01:47:56KittenKatgod non standard connectors piss me off *looks for the ipod and c200 cable*
01:48:01Lloreanamiconn: If you don't see it as problematic, why not be the one to re-implement it after the change?
01:48:37 Quit faemir (Remote closed the connection)
01:49:02JdGordon|amiconn: you said you dont understand bits of the email... respond then please... or we are going to have a situation where the bar *will* be broken and noone will have the energy to fix them
01:49:31amiconnBecause (1) I'm not good at implementing gui stuff, (2) it currently works and hence I would expect it to be kept working in a rework
01:49:48amiconnAnd I don't understand why the option is problematic
01:50:05Lloreanamiconn: So basically your argument is "it's too important to get rid of, *I* think it's easy so I'm unwilling to believe it will cause problems or difficulties, but even though I think it's easy I freely admit I don't have the knowledge to do it myself"?
01:50:19amiconnWhat's the difference between handling different button bar height, and a disableable bar? The latter just means button_bar_height == 0 ...
01:51:16JdGordon|amiconn: ok, the issue is that we cant have the bar at the bottom (outside the ui area) with it being allowed to show up whenever it wants, and we cant really use it in the ui area because the user could size and position that anywhere in the display
01:51:29amiconnLlorean: No, one of my arguments is that whoever breaks something is responsible for fixing it, unless there was an agreement of giving it up.
01:51:29JdGordon|so either its= needs to be static, or removed
01:51:32JdGordon|or stay broken
01:52:16amiconnIt doesn't show up whenever it wants. It shows up in all screens it is attached to, if enabled
01:52:41JdGordon|right... it needs to be *all*( screens, or none
01:52:53amiconnThat doesn't make sense
01:53:20amiconnAnd if your design is not flexible enough, something is wrong with that design
01:53:31amiconnSorry to say that
01:53:38JdGordon|no, the feature is broken
01:53:45JdGordon|the new design is fine
01:53:56amiconnIt's not broken atm, at least not that I know of
01:54:00JdGordon|and really... if its broekn then please help to fix it
01:54:37*amiconn already postponed several other things which need to be done....
01:54:45*JdGordon| suspects that he can probably just leave it as is, even though it will be technically broken, but nooen will notice

01:58:59pixelmaI guess then you'll notice
01:59:22JdGordon|notice what?
01:59:39JdGordon|umm... add a "if enabled" somewhere

02:13:54JdGordonwhich is why I'm going to be happy leaving it in a tehcnially broken state

02:14:34amiconnI mean the area around your 'ui' area, not the button bar
02:14:49JdGordonit will be up to the user (or themer) to make sure the buttonbar will be where it needs to be
02:15:11*amiconn would expect several different things from viewportification
02:16:18JdGordonyou know what the answer there is going to be...

02:21:15KittenKat*nods*
02:21:25KittenKatthink i figured out the c200 problem i'm having
02:21:37KittenKatrockbox reports a different product id vs the standard firmware
02:21:39KittenKathttp://pastebin.com/m19e4bdae
02:22:28KittenKatnow to find the source download ^.^
02:22:29rasherKittenKat: hm, that's the pid of a c200 in MTP mode..
02:23:06KittenKatit's set to MSC in the factory firmware
02:23:11JdGordonamiconn: yes and all that is coming.... right now we are discussin the buttonbar which is very legacy and causes issues in the new fun stuff
02:24:33KittenKatrasher: which one the working or non working pid?
02:25:14rasherKittenKat: the non-working one
02:25:34KittenKatrasher i thought that rockbox is alawys in MSC mode
02:25:35rasher0781:7450 = C200 in MTP mode
02:25:55rasherKittenKat: Yeah, I mean in the OF, it reports a different pid depending on whether it's in MSC or MTP mode
02:26:00Mikachuthe question is why the pid would matter when it's a standard ums device?
02:26:05rasherand 7450 is what the OF reports when in MTP mode
02:26:19rasherMikachu: well it shouldn't
02:26:51rasherLooks like it was misreported in the DeviceDetection wiki page
02:27:04KittenKatunder every distro of linux i have installed around the house it just sits there when connecting via rockbox firmware and does nothing. not allowing me to mount it in any way
02:27:29pixelmait does
02:28:02rasherWhich could mean Rockbox is using the "wrong" value, which means some software thinks it's an mtp device, based on the pid, and doesn't even see that it is in fact MSC
02:28:07KittenKatin the oe firmware it works good
02:28:08pixelmaat least OF in MSC gets a differnt PID than OF in MTP mode
02:28:23KittenKatworks well*
02:28:25rasherpixelma: and Rockbox appears to be using the MTP one
02:28:31KittenKatdamn i'm sleepy again
02:28:33Mikachui doubt linux would care about this though
02:28:48rasherWhich *shouldn't* matter, but hal could be basing its decision on the pid
02:28:51LloreanTechnically it's still the fault of the host software, since PID isn't supposed to be a valid way to decide what to use.
02:29:01pixelmaunless it's the Ubuntu bug
02:29:08rasherLlorean: Certainly.
02:29:09LloreanIt sounds like it's just a variant of the ubuntu bug
02:29:11pixelmaor hal
02:29:15Mikachutechnically there could be both an ums endpoint and an mtp endpoint on it, right?
02:29:21LloreanSame faulty design idea, but used somewhere else.

02:30:17KittenKatdosent matter who droped the ball, shouldent the rockbox firmware report the proper pid since it's known that some software uses pid to determine mtp/msc?
02:30:52KittenKatshould be a simple single line of code change on the rockbox end
02:30:56pixelmarasher: the reported PIDs had been wrong on the DeviceDetection page for the c200 until recently. I slightly doubt that's the reason Rockbox uses the "wrong" one though
02:31:17rasherpixelma: If I were to find a pid for the c200, I'd look there..
02:32:03pixelmawell, just thought gevaerts had an c200 himself and would have checked but yeah, there's a chance it explains it
02:32:22LloreanKittenKat: Well, it does matter who dropped the ball if someone, like you, still needs to report the bug to the people who are *actually* doing it wrong.
02:32:43rasherpixelma: It was added by zagor it seems
02:32:53rasherpixelma: http://svn.rockbox.org/viewvc.cgi?view=rev&revision=15758
02:32:55LloreanIn many cases we're going to have to use PIDs that are normally used for MTP devices as UMS devices
02:33:00LloreanFor example, the Gigabeat S
02:33:08LloreanWe can't solve the problem there, and we're doing nothing wrong n the first place.
02:33:19pixelmarasher: ah, and Zagor also put the wrong ones on the wiki page
02:33:37LloreanSo, yeah, who dropped the ball kinda does matter in the longer term
02:33:49rasherShould I commit this change? There's no harm in it, and if it turns out it fixes it, that's even more to point the finger at in a bugreport
02:34:00Lloreanrasher: Yeah, it should be fixed.
02:34:08KittenKatLlorean i've been coding for a long time... two wrongs dont make a right. if your firmware reports incorrectly and the software uses an unreliable detection method both parties should fix their problems
02:34:10LloreanBut whatever's doing the detection based on PID really needs to be identified.
02:34:17pixelmawas the problem only reported for c200s or also e200s?
02:34:19LloreanKittenKat: Our firmware doesn't report incorrectly
02:34:28LloreanKittenKat: PIDs identify hardware, not capabilities. So, the PID is 100% correct.
02:34:29CIA-69New commit by 03rasher (r21582): Use the USB pid normally used by the OF when in UMS mode. This might make misbehaving pc software play nice.
02:34:50rasherpixelma: also e200s I believe
02:34:59KittenKat*shrugs*
02:35:09LloreanKittenKat: You complaining to the other people as well, or just us?
02:35:22KittenKati'm complaining to the hal ppl also
02:35:56rasherKittenKat: See if the next round of builds "fix" it and use that to point more of a finger at the hal dudes
02:36:10KittenKati think it's a hal problem
02:36:19KittenKatit's kinda a 2 part problem
02:36:34LloreanThe USB-IF gave us no uncertain terms that it's allowable to use the same PIDs even if we switch a device that was previously MTP to UMS.
02:36:59rasherIt's not a 2 part problem at all.
02:37:21rasherHAL is not using the proper mechanisms to check the capabilities of the device. That's all there is to it.

02:38:38 Quit efyx (Remote closed the connection)
02:38:44KittenKataka 2 part problem. factory device works fine, your firmware dosent since it gives the mtp pid when it's using ums
02:39:00rasherKittenKat: it's not an "mtp pid". It's a pid belonging to that device
02:39:02KittenKatyour firmware should follow the OE pid shit
02:39:12rasherKittenKat: There's no rule at all saying we should
02:39:17KittenKatso non patched computers work fine, hal should fix their shit
02:39:20rasherThe bug is in HAL. Squarely.
02:39:32pixelmait doesn't anymore - and it would be even allowed to use the same
02:39:53LloreanKittenKat: There are cases where the OF doesn't even support UMS where we do. In those cases the problem still exists, because HAL is broken
02:40:16KittenKati've been coding a long time you cant alawys get the true cause of the problem fixed and therefor you need to patch yours to work around the bug you cant fix
02:40:44*rasher facedesks
02:40:48KittenKati expect hal to be broken for a while
02:40:50rasherThat doesn't mean there is *any sort of problem*
02:41:00LloreanKittenKat: We shouldn't introduce a bug to fix someone else's bug.
02:41:12KittenKat*shrugs*
02:41:26KittenKatyou guys should be doctors lol
02:41:39linuxstbLlorean: Why is it a bug for us to use the same PID as the OF in UMS mode?
02:42:02Lloreanlinuxstb: No, it's a bug for us to code around this behaviour in other cases though.
02:42:15KittenKatlinuxstb because it's not their "problem"
02:42:34Mikachulinuxstb: "<Llorean> [...] There are cases where the OF doesn't even support UMS where we do.", so then we have to use the mtp pid i suppose
02:42:35linuxstbLlorean: Are we talking about other cases?
02:42:42linuxstbMikachu: Yes, I know that.
02:42:52Lloreanlinuxstb: KittenKat seems to suggest the goal should be "make it work no matter what"
02:42:55rasherMikachu: Please see if http://build.rockbox.org/dist/build-sansac200/rockbox.zip "fixes" your issue

02:43:12rasherKittenKat: Please see if http://build.rockbox.org/dist/build-sansac200/rockbox.zip "fixes" your issue
02:43:18linuxstbOn all other devices where there are two different IDs for MTP/USB, Rockbox uses the USB one. It doesn't seem the intention that we don't on the C200.
02:43:19rasherIf it does, rain hellfire on the HAL people
02:43:27linuxstbs/USB/UMS/
02:44:13*linuxstb sees rasher's commit, so doesn't know what we're all arguing about...
02:46:23pixelmaif the reports are for e200 too and Rockbox uses the correct MSC PID there though then there must be another reason for HAL to fail
02:46:47rasherpixelma: I think hal expects mtp for the e200 because of the magic mode

03:03:06tmztif the hal xml files could be cleaned up to detect if rockbox was running somehow it could expose the device differently

03:24:10KittenKatreally?
03:24:19rasherJust that. We changed the pid to 7541 since it wasn't supposed to be 7540, but that this still doesn't mean they aren't in the wrong from making assumptions based on the pid.

03:27:35rasherLlorean: Sure, but hal also puts hints like supported audio formats etc for programs
03:28:46LloreanWell, we can decline to provide that package but still at least expect it to honor UMS, right?
03:29:12rasherIt certainly should
03:29:15LloreanIf their project wants to provide information, fine, whatever, but it shouldn't get in the way of standard USB stuff.

08:31:02padd1spitting out tonnes
08:31:08padd1then, we crack the 6g
08:31:15padd1we have hold of the firmware
08:31:29padd1we can do whatever eg rockbox
08:32:04markunwell, if you want to port rockbox it's nice to at least know what CPU it is using.

08:55:30padd1no
08:55:36padd1we think either 128
08:55:42padd1or 256
08:55:49GodEater128/256 what ?
08:55:54padd1we plan to get an old 6g and dump the ram and take it apart
08:55:56padd1to find out
08:56:00padd1oh bit
08:56:15GodEaterAES / Blowfish / Twofish ?
08:56:29GodEater<insert other crypto agolorithm of your choice>
08:56:53padd1hmm
08:57:05padd1that's what we are dumping the ram to find out
08:57:12padd1that's the only way, right
08:57:20padd1but, probs AES
08:57:34padd1unfortunately, dumping Ram destroys the ipod
08:58:14funmando you want to dump RAM content while the iPod is running? I don't understand how that can help figuring out the algorithm used

09:15:23padd1is why is that the RAM, in update has the key
09:15:29padd1that is taken from the rom
09:15:40padd1the rom is too hard to take out
09:16:20funmanif their software is well codec the key wouldn't be kept in RAM, and having the key still doesn't tell you which algorithm is used

09:16:33markunyou can't take the ROM out if it's inside the CPU (as with the ipod nano 2g)

11:37:34funmanamiconn: thanks, I have put this change into my diff
11:37:40funmantmzt: SD neither ;)
11:37:44tmztsomebody from google reported 50mbps for sd card
11:37:56tmzton msm7k hardware
11:38:13funman12mbps makes sense then (same order)
11:38:13tmztnot sure how targets' dma compares to that
11:38:18amiconnConversion from clocks to bytes is SPI specific. The timeout is given in clock cycles, but SPI *always* transfers bytes
11:38:29amiconnSo dividing by 8 makes things easier
11:38:32tmztthe interface is 2bit?
11:38:34funmantmzt: 12mbps is what the card reports, not a measurement at all
11:38:47tmztokay
11:39:11tmztthat was probably 4bit at 46mhz
11:39:40funmanamiconn: i merged the tCardInfo (mmc) and tSDCardInfo structures, now i need to make read_timeout and write_timeout meaningful on both SD & MMC drivers. timeout is not used by SD drivers at the moment but I will change that soon for Sansa AMS
11:40:01tmztthough that doesn't seem to add up
11:40:46funmanamiconn: well I would think timeout is expressed in time units (clock cycles or seconds)
11:42:31amiconnhmm
11:42:32funmanis the timeout dependant on the size of data transferred ?

11:52:51wincentI modelled it after zxbox.make.
11:52:55funmanis plugin.h inside an #ifdef block? perhaps gcc wouldn't include it when generating the dependencies
11:53:07funmanand zxbox dependencies are rebuilt fine?
11:53:45wincentYes, I saw after some updates of plugin.h that zxbox was recompiled completely and pdbox was relinked only.

16:06:30Tornethen shut down and restart, the db will be blank
16:06:36evert_ok
16:06:48Torneif that doesn't work you have a very interesting bug indeed
16:07:14funmandatabase_tcd.* even
16:07:20funmandatabase.ignore can be useful
16:07:25Torneoh, er, yeah
16:07:29rasherInitialize now should be from scratch.
16:07:47Tornerasher: yah, but evidently *something* isn't working, so i figure it's worth a try
16:08:00gevaertsevert_: which revision are you using? Also, are you sure there's no trash directory or similar on the player?
16:09:02funmandouble entries in the database do not happen (only) because of trashes directories
16:09:45FrankTM16:05 < Torne> even reinitialising it from scratch?
16:09:54FrankTMhas that bug been fixed ?

16:11:42funmanit seems that no, i'm not sure a cause have been found
16:12:12evert_ok, thanks, it seems fixed by deleting the database_tcd* files and then initializing it again :)
16:12:24FrankTMevert_: do you have auto-update enabled?
16:12:43evert_i think so
16:12:45evert_normally yes
16:12:47rasherI'm almost willing to bet that it's not just a single bug. Much like "the Firefox memory leak"
16:12:49gevaertsFrankTM: there's been some recent (post 3.3) database work that should make it a lot better
16:13:19FrankTMah. i'll upgrade tonight then

16:53:14gevaertsThat means that running 5 single core builds instead of 1 -j build will finish 10 builds in 308 seconds instead of 550 (assuming enough RAM is available)

16:56:05gevaertsThat would also give single-core hosts a fairer chance of not getting their builds killed, which means even more savinmgs

18:42:50FlynDiceyes been running for 2 hrs now and no lockups
18:43:20kugelis that dependant on something?

18:49:22JdGordon|gevaerts: say what you mean :D
18:50:36JdGordon|gevaerts: after looking at it last night I was gong to suggest a really easy way of doing it by manually fudging with the .playlist_control file, but apparently it doesnt have a "add directory" command like I thought it did
18:50:39***Saving seen data "./dancer.seen"
18:51:18gevaertsJdGordon|: well, it works now. Adding the rb->playlist_create() was the most important bit
18:51:57Tornegevaerts: that sounds like a good feature, but i havne't looked at the patch
18:52:14Tornei would but i need to leave veyr soon :)
18:53:25gevaertsJdGordon|: stopping playback first shouldn't be needed, as the plugin grabs the audio buffer anyway. That's also the reason why I made it exit immediately. It would have to reinitialise everything
18:53:57JdGordon|ah yes
18:54:14mcuelenaereGrahack: also don't lcd_update() after lcd_clear_display(), that way it doesn't flicker that much :)
18:54:16JdGordon|and playlist)_create() presumably resets the resume info which was another problem
18:54:26mcuelenaere(when scrolling)
18:54:38kugelFlynDice: disable_irq shouldn't be needed then I guess
18:55:00gevaertsI think so, yes. I had assumed that playlist_remove_all_tracks() would leave the playlist in a clean state, but that's apparently not the case
18:55:19gevaertsI then went to look at how pictureflow does this, and stole some code
18:56:10kugelgevaerts: is the playlist stored over a reboot? I was having problems with this while doing this on PF
18:56:34kugeloh, I didn't read your last sentence :P
18:56:44kugelpictureflow uses the tagcache way of building a playlist
18:57:14gevaertsAnyway, this is purely new code so it can't break anything existing, so I think it

19:26:41funman_kugel: it's specific to as3514 (sansa e200v1 and c200v1 use it)
19:26:57Grahackmcuelenaere: yes I read the logs. I updated the string.rep thing. I cameback to know your general idea about my files too. Wo what do you think ?
19:27:13funman_kugel: and the sd_command() functions use this kind of data array
19:27:20funman_sorry my last comment was for bertrik
19:27:40bertrikfunman_, I wasn't criticising your patch :)
19:27:50kugelfunman_: we use it too
19:28:00funman_bertrik: well i wasn't thinking it's a critic, but your question is interesting
19:28:13kugeladc-ascodec.c is probably a better name
19:28:17funman_the SD controllers use 32 bits registers so it's easier to copy into a 32bits integer type
19:28:17bertrikI just see no good reason to store it as a couple of 32-bit words
19:28:38markunthis looks like pretty good news: http://forums.rockbox.org/index.php?topic=6518.msg152565#msg152565
19:29:15markunhopefully it will be possible to decrypt, but also to encrypt firmwares for the nano 2g
19:29:38saratoga_the linux4nano people claim to have got thier code to run on the Nano2G
19:29:40*bertrik needs to hurry up with s5l8700 stuff
19:29:52funman_i thought the notes vulnerability was not exploitable
19:30:26*bertrik mumbles something about pudding
19:30:30saratoga_we'll see what they have soon enough I guess
19:30:35markunsaratoga_: that's pretty cool, but then I don't understand why this dump was so difficult
19:30:37saratoga_but they claim: "tof, Taylor Gordon, Cory Walker and Dan Andrews (donator of the iPod nano) succeed to inject some working ARM assembly code within the iPod Nano firmware (victory message here"
19:30:59funman_bertrik: checking the bit 0 in IRQ_ENRD_2 results in a dead lock, I think it can only be used with interrupts ?
19:31:13kugelthe pp ascodec seems to yield indeed
19:31:31markunbertrik: I'll try to get you another S5L8700 target soon then :)
19:31:51markun(the M6SL in case you tink I have a nano for you..)
19:32:09bertrikfunman_, the datasheet says (edge) for this bit, so maybe this bit is only high for 1 read (i.e. clear-on-read)

20:30:00*gevaerts starts to fix
20:30:24JdGordon|it probably wont make much difference, but its nice to use the whole buffer so people can have massive lists
20:30:38JdGordon|that is possibly happening in rfa.rock already
20:31:33gevaertsit won't make much difference, but it's break-proof

20:45:18gevaertslowmem targets will have to make do with 6977 folders
20:46:02JdGordon|hmm... you're using the plugin buffer for the order array and the audio buffer for the folder name buffer?
20:46:07gevaertsJdGordon|: I allocate an array of ints, and shuffle that. The list of directories is actually in the audio buffer
20:46:15JdGordon|snap!
20:46:22JdGordon|right, yeah that should be sweet

20:55:56JdGordon|umm..

21:02:35 Join funman [0] (n=fun@rockbox/developer/funman)
21:04:04gevaertsanyway, that's plenty. If you assume that a normal album takes about 100MB (about 192kbit,1 hour), you'd need a 400GB disk to reach that limit. The largest disk I know of you can actually buy is 320GB
21:04:28kugelpretty close already
21:04:55kugeljust grab dbestfit from PDa and use malloc :p
21:05:06gevaertsyes, but they're probably not going to make new bigger PATA disks
21:06:16gevaertsAnyway, I've never heard complaints from people who hit that limit
21:06:20kugeland 100MB is pretty much for an album
21:06:32JdGordon|but we shouldnt go out of our way to set artificial limitis
21:06:35BryanJacobsbut they could make bigger flash drives, and there are flash->PATA adapters :-P
21:06:42BryanJacobskugel: not if it's FLAC
21:06:57kugelBryanJacobs: he's assuming 192kbit/s
21:07:14BryanJacobs192k MP3s are like 1.5MB/min, no?
21:07:25funman95% of my albums are less than 100MB
21:07:41amiconnAll limits in rockbox are tradeoffs, and those which have a significant impact on memory usage are therefore configurable
21:07:44BryanJacobsmy whole music collection fits in 12GB if I convert to MP3
21:07:51MikachuBryanJacobs: 1.37
21:08:01gevaertsJdGordon|: this one isnt't very artificial. The only way to fix it would be to use dynamic sizing for the directory names, and not just allocate MAX_PATH bytes for them

21:08:18funmanamiconn: (sorry for repeating) anything against http://pastie.org/530998 ?
21:08:24gevaertsfunman: how big are they on average?
21:08:52kugelyou might want to look into that (unless you feel comfortable with that high limit, which sounds reasonable)
21:09:05amiconnfunman: Not really, but I don't see the necessity.
21:09:18gevaertskugel: it's an old limit. I'm not very bothered by it, as long as what I
21:09:26amiconnThe extra calculation is small though. Btw, did you try replacing / with >> and % with & ?

22:52:18mcuelenaeremicroSD that is
22:52:34funmanmcuelenaere: i'm a bit disturbed by the references to "mmc" in ata-sd-jz4740.c :)
22:52:43mcuelenaereyeah, that's not really my code
22:52:47mcuelenaereI know, it's a mess .. :(

22:53:05funmando you know in which word-order the cid & csd are stored in memory ?
22:53:06kugelmc2739: can you try a build using 192MHz (there's a patch somewhere around offering such profiles which automate frequency selection), I'm wondering if the boosting act as such, or the voltage causes the problems
22:53:14Tornegevaerts: that doesn't help though does it?
22:53:30Torneor is there some trick i'm missing
22:53:40mcuelenaerefunman: no idea, I saw that the code stores it in the way the SD interface receives it
22:53:43kugel192MHz as CPUFREQ_MAX
22:53:45funmanor in other words does the debug screen -> disk info look correct for manufacturing date / product id serial number ..
22:53:50mcuelenaerenope
22:53:59mcuelenaerethat's why there's a TODO at that function ;)
22:54:13funmandisk info debug menu read this info directly from the registers
22:54:17mcuelenaeresome of them look/looked correct, but most don't

22:56:47funmanwhy is mmc_request->response 18 bytes and not 16 ?
22:57:05funmanthe real data seems to start after the 1st byte
22:57:09gevaertsTorne: /me thinks that Torne should have another look at the manual :)
22:57:17*Torne grumbles :)
22:57:30funmani want to reverse the order in which cid/csd registers are stored and i need to correct the uses in all drivers
22:57:52funmanto avoid touching this driver I could write another implementation of card_extract_bits for SD
22:57:57Tornegevaerts: aha
22:58:06Torneso that picks the next directory from the fs?
22:58:13funmanmy last commit is wrong : the cid/csd registers need to be stored most significant word first
22:58:14mc2739kugel: it already works at 62mhz and 248mhz without the voltage change
22:58:33mc2739back later
22:58:34gevaertsTorne: depends on your settings. It can also pick a random one
22:58:55kugelmc2739: I know, but now changing the frequency isn't instant anymore, and more complex
22:59:35Tornei was gonna say "but then you have to rebuffer" but i guess with a big playlist like your code generates then it's likely to have to rebuffer to skip by a whole album ayway
22:59:37funmanmc2739: i just noticed a lock up with my microsd card

23:00:19kugelI'm wondering if we need to boost on (microsd) data transfers, just to keep the voltage up
23:00:30gevaertsTorne: yes. If you never skip, the new feature is better. Otherwise not
23:01:04Tornewhat does next folder do if you're playing a tagcache playlist then?
23:01:07Tornenothing?
23:01:45kugelthat probably wouldn't even cost much
23:01:47mcuelenaerefunman: I didn't really change much in the code, just adapted it to Rockbox
23:01:51gevaertsI'm not sure. probably not what you want
23:01:57kugelon most transfers (rebuffering), we're boosting anyway
23:02:07*mcuelenaere should really write a new SD driver but doesn't really feel like doing so..
23:02:10*gevaerts uses neither the next directory keys nor the database

23:02:39FlynDice_kugel: isn't microsd transfer dma so should the processor core voltage even matter?
23:03:05kugelobviously, it's affecting more than only the core voltage
23:03:08gevaertsI guess the same thing. It's not really meant to be used with multi-directory playlists, so who knows what will happen?
23:03:15Bagderso did anyone around here get to see any nano2g romdump ?
23:03:39*gevaerts just wrote some code to generate a playlist, and suddenly people assume that he knows how playback works...
23:03:42Tornehehe
23:03:46Torneok, i'll have a look/fiddle later
23:04:03Torneif it does something useless it might be nice if it went to the next file that was in a different directory to the currently playing one?
23:04:16Tornewhich would do soemthing useful for nonshuffled playlists
23:04:18kugelTorne: you can't dirskip in tagcache playlists
23:04:28Tornekugel: right.
23:04:44funmanmcuelenaere: would you help me cleaning it if i break it with my changes?
23:04:59gevaertsBagder: did you see my -j calculations at http://www.rockbox.org/irc/log-20090701#16:48:17 ?
23:05:38mcuelenaerefunman: you mean the Ingenic driver or the generic part in Rockbox?

23:09:33gevaertsZagor: hm, now I think about that particular bit a bit more, it doesn't make much sense...
23:10:19kugelwincent: I was just wondering if you can use the sin/cos table that's in rockbox (instead of that giant one which bloating the plugin buffer)
23:10:38Tornegevaerts: could probably be done, get_next_dir in playlist.c already does a huge amoutn of messing around to search the dircache for it, i doubt scanning the playlist would be any worse :)
23:10:51gevaertsZagor: currently if a multicore host and a single-core host are doing the same build, the single-core one will likely get killed. If all builds are done with -j1, chances will be evened out, but I don't think (now) that this will make much difference in total time
23:10:53mcuelenaerefunman_: just commit, I'll shout when you broke something ;)
23:11:03wincentkugel: Where does this table reside?
23:11:23funman_mcuelenaere: well i just won't use the common code on ingenic
23:11:35gevaertsTorne: indeed. Just some strrchrs and strncmps I guess
23:11:43funman_i'm still looking at PP code, then i'll move some code out from PP & AMS code into sd.c

23:12:24notlisteningrasher, if you have a minute this one is stopping me at the moment http://pastebin.com/d4ffb1625
23:13:29kugelgevaerts: I think it would make a difference until we have 106 build clients or have the clients to parallel builds
23:13:58funman_kugel: no :/ where is it ?
23:14:31wincentkugel: Thank you very much for pointing this out, I think I will change to the sin/cos table of rockbox later.
23:14:35Zagorkugel: but we actually don't want multiple clients building the same target it we can avoid it. hence it's better to do each build quickly instead of doing many builds slowly.
23:14:44kugelfunman_: http://www.rockbox.org/tracker/task/10397
23:15:05kugelZagor: no, I mean 1 client doing multiple builds :)
23:15:17gevaertsZagor: maybe we should just try both ways. It's going to be hard to work out the numbers from scratch
23:15:19Zagorkugel: yes, that means each build will be slower
23:15:22kugelinstead of -j, since gevaerts showed the depgen limits
23:15:42Zagorgevaerts: true. statistics rule.
23:16:20kugelwincent: I don't know what accuracy you need though, the rockbox' one has only 90 values
23:17:13gevaertsIf you never allocate the same build to different clients, the -j1 approach will win. If you multiple-allocate lots of builds, the -j approach will get a lot closer and maybe win. That means it also depends on the build client vs builds ratio
23:18:25Zagorwe should focus on getting it up and running at all, so we can collect statistics
23:18:26Bagderhm, the romdump is little endian?
23:18:46BagderZagor: the main problem atm is the client's too frequent dyings
23:18:53wincentkugel: Yes, the one from Pure Data is way greater. I will look into this later.
23:18:57ZagorBagder: dying?
23:19:05Bagderyes the 0-length pipe thing
23:19:09*Torne still needs someone who nderstands the beast to explain some of the boot process :)
23:19:29Bagderthat, and the make process not being killed properly
23:19:41Zagoroh, I see that now. oddness.

23:28:58Zagorgevaerts: what is the patch you are talking about?
23:30:30gevaertsZagor: http://pastie.org/524770.txt which didn't solve it, and then http://pastie.org/524789.txt on top of that (untried, and a bit voodoo)
23:31:18gevaertsbasically the problem is that you just kill the shell, but not any childprocesses of that
23:31:50gevaertsthe second patch is reversed
23:32:10Zagorah, right. so how do we kill the whole process tree? iterate through the pids?
23:32:38Zagor-$pid or -signal seems a bit... arbitrary. is that documented anywhere?
23:32:50gevaertsFrom /bin/kill, just use the negative of the parent pid. In perl, it's a bit confusing
23:33:29gevaertsso maybe `kill -9 -$pid`? :)
