00:00:09Bagder103 builds in the table
00:00:22 Quit mirak (Remote closed the connection)
00:00:53saratogamaybe we could have seperate tables for targets and bootloaders
00:01:18saratogathough i guess thats not really any more sensible then putting them together
00:01:53funmanlow_light: is akcodec initialized before or after first display of "AKM Codec Test started" ?

00:16:11low_lightfunman: in the OF, the GPIOB bit is set during a sys_init type funciton, separate from the codec stuff.

00:19:01 Join LambdaCalculus37 [0] (n=rmenes@rockbox/staff/LambdaCalculus37)
00:21:21LambdaCalculus37Are we looking to build new bootloaders for Version 3.3 when it releases?
00:23:57LloreanIf we're going to include USB we're going to need to.
00:24:15*Llorean would really like to see the charging issue solved on iPods first.
00:24:19soapIs USB going to be included on PP even with the charging issues on all (????) iPods?
00:24:23soapjynx.
00:24:29Lloreansoap: There's a patch for it in the tracker, I think
00:24:32LloreanFrom dreamlayers.
00:24:49soapThe "dumb" patch which assumes you have a power supply which can provide 500ma?
00:25:04LambdaCalculus37Yeah, I think that's the one.
00:25:16LambdaCalculus37Llorean: What's the FS# (if you remember it)?
00:25:20LloreanI can't remember, sorry.
00:25:26LambdaCalculus37I'll search.
00:25:28soapThat one works very well for me - but I think that is the last thing which should be in a release.
00:25:40Lloreansoap: Why?
00:25:44low_lightfunman: yes, but I didn't see it in the OF FW file. I believe I tried it on the 820/925, but it was setting that GPIOB bit that got things working for me.
00:25:53Lloreansoap: All it needs is an option like the H300 has.
00:26:08soapI'm thinking of #8802
00:27:00funmanlow_light: can you share your yh920 disassembly ?
00:27:09LambdaCalculus37http://www.rockbox.org/tracker/task/8802?string=8802
00:27:14Lloreansoap: IIRC the H300 has an option that basically boils down to whether or not to request 500
00:27:24soapLlorean, because whatever amperage we're pulling w/o that patch fails even to trickle charge my 5G when it is idle, and if that patch is "dumb" enough to pull more amps than it should - we'd be creating a monster.
00:27:40soapLlorean, but the H300 charges on the lower setting, does it not?
00:27:52soapAnd does it _take_ 500 or _request_ 500?
00:28:01LloreanI guess it takes.
00:28:09 Nick fxb is now known as fxb__ (n=felixbru@h1252615.stratoserver.net)
00:28:43Lloreansoap: I'm not sure what you mean by "creating a monster"?
00:28:51soapIf it takes, then you are absolutely right that is precedent, but how many of the iPods can charge in a current build w/o that patch?
00:29:01LloreanI'm missing something
00:29:08LloreanWhat does being able to charge in current builds have to do with anything?
00:29:25soapCreating a monster in that we are giving users two options. Option 1 being "pretends to charge but doesn't" and option 2 being "unsafe charging behavior".
00:29:44LloreanMy understanding is that the only expected "unsafe" thing about it is failure to connect.
00:29:56LloreanThe host will refuse its demand for 500 and it won't show up as a UMS device
00:30:02soapBecause if USB is enabled and there is no safe way to charge what has been delivered in terms of stable functionality to the user?
00:30:29LambdaCalculus37Since we may have new bootloaders, should we also bump the version numbers for e200rpatcher, iPodpatcher, and Sansapatcher as well?
00:30:36soap"Don't try charging from unpowered hubs or chargers which have lower ratings."
00:30:42Lloreansoap: We get better runtime than the OF. That means that, generally, we're using less power than them. If they can charge, they're probably getting 500 as well.
00:31:06LloreaniPod chargers have a rating of 1000 actually, or every one I've seen has
00:31:13soapand USB ports?
00:31:25LloreanCompliant ones are 500
00:31:38LloreanThe only ones that are a problem are ones that don't actually follow USP specifications, if my understanding is clear
00:31:39Mikachulsusb -v shows "MaxPower 500mA" for my ipod nano, i don't know if it means it's actually using that though
00:31:47soapsince when does Rockbox assume the user's hardware is acting in compliance.
00:31:57LloreanSince it's necessary to charge.
00:32:02soap?
00:32:25Lloreansoap: We assume the host supports UMS for UMS connections
00:32:33LloreanWe also assume it provides the amount of power USB is supposed to provide
00:32:36LloreanThat seems pretty reasonable.
00:32:46soapThe way I read dreamlayers' comment (the quote above) is do not use that patch and plug into a port (of any sort) which is not rated for 500ma.
00:33:01LloreanWe have an option "Unpowered connection" resting somewhere in the menus for people to turn on if they need to connect to an unpowered hub/port
00:33:26JdGordonspeaking of which.... egt around to testing the usb charge only patch?
00:33:47LloreanJdGordon: Just got back to my players last night. What FS# is it?
00:33:54pixelmajust a fyi (maybe interesting for tomers) - http://svn.rockbox.org/viewvc.cgi?view=rev;revision=21054 works well with foobar2000 and my c200
00:34:04JdGordon10198
00:34:08Lloreansoap: My understanding of *why* not to, though, is just that it will fail to connect.
00:35:41soapI don't get that from what dreamlayers said in the FS task.

00:37:29Lloreansoap: What he says doesn't indicate anything about what will happen.
00:37:48LloreanI'm just relaying what I was told when I came in here and asked several people about what the dangers of it would be.
00:38:18soapNot to mention the concerns dreamlayers brings up in his last comment (2009-03-25) regarding the use of said patch to charge through accessories. I take that comment to reinforce my belief that the caution is so that 500ma is not blindly drawn from a device incapable of safely delivering said current.

00:40:52CIA-38New commit by 03kugel (r21086): Samsung YH*: A few keymap tweaks (still nothing final yet) ...
00:41:36Lloreansoap: That's something we can never know without a lot of experimenting though.
00:41:57LloreanThere would be no way to tell in advance if accessories have over current protection.
00:42:02LloreanAnd we're not talking about charger mode
00:42:08LloreanWe're talking about during a USB connection
00:42:25LloreanDuring a USB connection (as we do have charger detection already and can distinguish) we should treat it like a USB port
00:42:43 Quit efyx_ (Remote closed the connection)
00:43:16soap(final thing I will say, as dreamlayers is likely the one to answer this) but the "monster" I spoke of is that. Giving a user the choice of "no charge" or "unsafe charge" seems really odd when the option of rebooting into Apple's Disk Mode is so (relitively) painless. "This might cause hardware damage, all the possibilities haven't been tested." seems like an odd disclaimer to make of a release.
00:44:18kugelthe samsung fails at charging for most of my usb ports too (in the OF)
00:44:47LambdaCalculus37My iPods charge fine on my MacBook, except for my iPod 2G since that has a bad FireWire port.
00:44:57soapLambdaCalculus37, USB charge?
00:45:21LambdaCalculus37soap: With the ones that support it, yes.
00:45:27kugellow_light: did you get that backlight?
00:45:39soapwhich models are that? A 5th gen?
00:46:00LambdaCalculus37soap: Both my video and my Color.
00:46:15soapMy fifth gen won't charge under any circumstances (charger or USB port) in Rockbox w/o that patch.
00:46:48LambdaCalculus37soap: Ahh, that's why. I was charging via the OF.
00:46:53pixelmathe only thing foobar2000 seems to not know about is the "key" I should be able to access with ACTION_USB_HID_MENU (Power button on c200) - it just doesn't "see" that button. Don't know whose fault it is though...
00:48:06*LambdaCalculus37 wonders if we should be creating a separate target for the GoGear HDD6330
00:48:50soapIs it known what iPods can USB charge currently in Rockbox (not OF) reasonably? (reasonable being playback stopped, backlight/LCD off, 12 hours or less)
00:49:32Lloreansoap: Even the OF isn't expected to work with low powered USB ports
00:49:37*Llorean just found it on Apple's site
00:49:38LambdaCalculus37soap: My brother's iPod mini charges well in Rockbox.
00:50:31soapLlorean, I've never had the OF fail to charge, even on my wife's 199x (P-II) laptop.
00:50:33 Quit matsl_ (Read error: 60 (Operation timed out))
00:50:45soapMaybe that laptop has a 500ma port - I don't know.
00:50:54LloreanIs it USB 2.0?
00:50:57soapno
00:51:23LloreanDoes it work with USB-powered disks?
00:51:36soapHDDs? No.
00:51:51LloreanI'm just sayin', the apple site itself says they aren't expected to work on low-powered ports (such as those in keyboards or bus-powered hubs)
00:52:29soapI have a bus-powered hub - I'll add that to my list of limited things I have the means to test tonight.
00:52:34LloreanIt doesn't even just say they won't charge, it says they will not work, which makes me think it may be a similar situation to what gevaerts mentioned (failing to connect on the request for 500, not able to reconnect after)
00:53:32Lloreansoap: I'm only suggesting we use the charging for when we detect it IS a USB connection and not a charger (we've already done that detection for years on iPod).

00:54:55soapOk, I have a dead Nano plugged into a bus-powered hub, in OF, dead battery.
00:54:59LambdaCalculus37low_light: Ping
00:55:15soap(well, will be OF, hold switch is on)
00:55:31Lloreansoap: Dead battery isn't the question.
00:55:35LloreanWill it connect to a computer?
00:55:41soapIt just did.
00:55:51soapgot enough charge to boot and connected instantly.
00:55:58LloreanApple's site says it won't work
00:56:04LloreanThen again, my Nano currently charges in Rockbox.
00:57:53*LambdaCalculus37 is reading some of the info on the GoGearHDD6330
00:58:51Lloreansoap: Willing to try with your Video?
00:59:07soapTry plugging it into an unpowered hub?

01:00:05LloreanThe Apple site suggests that Disk ipods are more problematic (it says the Nano and Shuffle will work even USB 1.1, while other iPods won't, and not to expect unpowered ports to work at all)
01:00:23soapPut the Nano on charge on a current (well current until kugel just acted) build with a battery @ 6%. Started battery bench, no playback, see how long charging takes.
01:00:51kugelwhat?
01:00:52soapNano is on a powered hub..
01:01:10soapI was teasing about the definition of "current", kugel.
01:01:30kugelah, heh
01:01:31LloreanJdGordon: Having issues with the patch. There was one failed hunk, I fixed it, but the error I'm getting is related to a different file (settings list, which isn't where the failed hunk was

01:47:54saratogafor what its worth blindly pulling 500ma off of any connected port is pretty typical
01:48:03saratogathe Sansas do it
01:48:47saratogain practice the 500mA specification seems to be the maximum a device can pull, but most devices supply much more to protect against non-compliant devices and people stringing multiple devices onto a passive hub
01:48:57kugelthe sansas do not have the problem of exessive current drawing while file transfers though
01:49:37Lloreankugel: Sansas pretty much had the same problem iPods do now before charging support went in.
01:49:58LloreanIt's not excessive. Most disk based iPods just draw more because there's a disk to spin, and they still pull the 100 that Sansas used to pull
01:50:06kugelIIUC, the problem with the ipods is, that they tend to even discharge when transfering
01:50:29LloreanYes, they do, but not because of any excessive activity
01:50:36LloreanJust because they don't yet pull full power from the PC
01:50:37kugeldue to the disk(?)
01:50:55 Quit lightbulbjim ("leaving")
01:52:19LloreanUSB has to be boosted. That combined with the disk (and I'm not sure, is the screen always lit?) leads to decent power usage just naturally
01:52:32LloreanMeanwhile we draw what is essentially minimal power.
01:53:04saratogathe e200s actually would have discharged with just 100mA too, since they needed about 150mA with the wheel light on IIRC
01:53:27Lloreansaratoga: I seem to remember whether they discharged or not seemed to vary from reporter to reporter back then
01:53:43saratogaprobably if they had the wheel light on
01:54:14kugeldid you messure what the wheel draws?
01:54:27saratogayes but i lost the notes
01:54:38saratogait was about 150mA with wheel + screen
01:55:11saratogai'm sure its in the october or november 2007 IRC logs if really needed
01:55:56saratogahmm skimming that task, whats the reason we can't just request 500mA ?
01:57:10Lloreansaratoga: Fear that accessories may not deal with it well because the Apple firmware distinguishes what's connected by voltage, mainly, I think
01:57:47LloreanAnd it would be nice to have a setting for "low draw" mode for when someone really wants to hook it up for a short time to something that doesn't provide full power, I guess.
01:58:09saratogaLlorean: does the case where its connected to a USB port and the OS grants 500mA work ok?
01:58:18LloreanAs far as I know, yes.
01:58:24LloreanI haven't tested it personally.
01:58:32saratogaso the problem was just AC chargers?
01:58:39kugellol, the OF is messed up with rockbox on the samsung
01:58:48kugelscreen morrored and flipped
01:58:53LloreanAC chargers (which I believe we can already distinguish on the iPod anyway), Accessories, and what happens if the OS doesn't/can't grant 500
01:59:32saratogaand I suppose theres no way to detect voltage sag and stop charging?

02:54:25soapI have been using that patch daily since it was posted and have successfully charged on a variety (ok, four) of computers and wall chargers. This is with my iPod Video. I was getting no appreciable charge w/o the patch.
02:54:49 Quit evilnick_home (Read error: 60 (Operation timed out))
02:55:25soapI was getting no charge either via USB computer ports /or/ via my Griffin cigarette lighter -> usb charger. I did not test w/o the patch on the Apple wall charger (which I also have).
02:55:48Lloreansoap: The griffin one, does it detect properly as a charger or do you have to hold Menu?
02:55:56soapIf that is a test which anyone finds desirable (with battery bench) just tell me and I can do it.
02:56:08soapLlorean, let me go double check.
02:56:14*Llorean never really did find out of when we added USB support, we broke the old charging we used to have.
02:56:19Llorean*out if
02:57:29soap(side note) I so very rarely touch the OF, when I press Menu+Select the piezo startles me. BRB.

03:01:45soapBoth the Griffin PowerJolt (12v -> USB) and Apple's Original AC->USB chargers are detected as chargers by my iPod Video.
03:01:51soap(in Rockbox)
03:02:13LloreanThose chargers used to charge while playing in Rockbox just fine (as in pre-USB)
03:02:21LloreanDid we have some code that's disabled now that we have a proper stack?
03:02:32LloreanWell, those *sorts* of chargers.
03:07:24soapI'll post battery benches tomorrow. Nano via USB and Video via wall charger. Will switch and do the opposite the next night.
03:08:26LloreanWell, you already said it doesn't seem to charge for you via the cigarette lighter adapter.
03:08:33LloreanI know my Nano used to charge by my Griffin one just fine.
03:08:49LloreanThen again, Nanos use a bit less power so it may have just been that I was coming in under the line.

08:00:01amiconnUnhelpful: What is the advantage of the new scaler math? It might be better to use it on SH1 as well even if it is a little slower, if there are other advantages
08:03:44*JdGordon curses the 3 month release cycle.....
08:03:52JdGordonits almost lockdown/cleanup time again
08:07:49LloreanJdGordon: Does the list viewports patch work pretty well?
08:08:01LloreanIt seems a pretty big change to be trying to squeeze it in right before the freeze.
08:08:17JdGordonfrom my limited testing it appears to work
08:08:53JdGordonthere will probably be small redraw glitches in the wierd screens which can be fixed when found
08:09:18JdGordonI guess that means you saw the tracker comment? :p
08:09:23LloreanYup
08:10:08LloreanI mean, if you got it in during the next few days, that'd give time for it to be tested (so that it could be reverted for the branch if it turned out more problematical than expected)
08:10:38JdGordonkugel has been working on it for ages now so im pretty confident the big bugs are known and fixed
08:11:37LloreanDoes it work well with remotes?
08:11:40JdGordonI assume that if/when background WPS goes in, we will want to keep the current statusbar avilable (at least for a while anyway)
08:11:58JdGordonit *should*, I cant imagine why it wouldnt....
08:12:12amiconnUnhelpful: The SH1 sc_mul_u32_rnd does add %[t2], %[r] twice, and seems to miss add %[t3], %[r] instead
08:12:55LloreanJdGordon: Either way, with short freezes, we should be being careful about what goes in for the period leading up to them too.
08:13:12LloreanIt shouldn't be a race to get a feature done before the freeze.
08:13:19amiconnOtherwise this is a quite clever way to handle the 64 bit intermediate (exploiting the fact that it actually isn't full 64 bit)
08:13:58JdGordonmeh, well, I actually thought there was nothing interesting in the next release.. completly forgot about the recent (and enabled) additions
08:14:20amiconnLlorean: Imo it wouldn't be wise to have a freeze around devcon
08:14:39LloreanJdGordon: It doesn't really matter whether there's something interesting, the idea is just to have a regular "stable" release.
08:14:50JdGordoni know... i know...
08:15:18Lloreanamiconn: I don't know if it's that big of a deal.
08:15:43LloreanJdGordon: Does list viewports give anything user visible without background WPS?
08:16:09LloreanJdGordon: And as I said, I'd be a lot more happy if it got in *soon* so there could be some more widespread testing before the freeze. ;)

08:16:31JdGordonamiconn: yeah, it might mean some nasty bugs get fixed though?
08:17:05JdGordonLlorean: umm, no not really... without the WPS addition it just lets you position the list to fit in a ncie background or something
08:17:36*JdGordon thinks that background images could cause problems here
08:17:44LloreanJdGordon: Well, that's still something user visible. Cause problems how?
08:17:51 Quit jmillikin (Read error: 110 (Connection timed out))
08:17:58JdGordonwho thought it was a good idea to let users choose a differnt image in the wps than in the menus? :/
08:18:21JdGordonthe menu background will get shown under the wps parts i tinhk
08:18:27LloreanAh, that's not good.
08:18:46JdGordonthats also the fault of the themer though
08:18:59JdGordonthere isnt really anything that can be done about that
08:19:26JdGordonuntill we allow each viewport to specify its background image
08:19:39LloreanAs long as current themes aren't broken, and new themes can be made "properly" I don't really see a problem if it's also possible for people to make them badly
08:21:19LloreanSo the WPS background is treated as a sort of "full screen" backdrop, while the list backdrop only shows up in the list viewport, or what?
08:22:34JdGordonright now its a bit of a hack (which probably wont get any better)... the wps is told to update, that will take out the whole screen if the themer isnt careful, the list *should* then get drawn where it was told to

08:25:23LloreanI seem to recall significant battery life savings by just putting it in the list rather than the WPS during playback.
08:25:52JdGordonwell, yes.. but its pretty :)

08:28:45LloreanI imagine "update WPS while list is shown" will be an 'invisible' setting, set by themes, rather than a user setting? Basically, when the WPS is loaded, it'll tell Rockbox via this setting whether some part of it is visible in the list and needs updating?
08:29:26LloreanAnd I guess, defaulting to "Off" and needing to be added to existing themes unless there's a better way
08:31:08JdGordonwell, it would be up to the theme .cfg more than the .wps i tihnk...
08:31:16LloreanSorry, yeah, theme.

12:59:06Rasiwork-in-progress
12:59:16Rasiit only talks about the C200

12:59:38n1sRasi: even for ports that are almost good enough to be "supported" there's no guarantee that they ever will be...
12:59:41Rasiah
12:59:41funmani'll change it to mention explicitely e200v2

13:00:05Rasiyea yea, that wasnt my question at all :)
13:00:23funmanRasi: fixed :) - so you wanted to help .. ? :)

13:00:35Rasifunman: depends on how i can :)
13:00:41AlexPAnd there is a reason it isn't supported yet - feel free to dive in and help develop, but until it is supported it isn't really for end users
13:01:26Rasiyea i know that
13:01:42Rasimy question was only about me being too blind to see that it actually IS mentioned :P
13:02:01funmanRasi: if you want to help on the technical side first you should read the last forum pages, and flyspray tickets mentioned here. You can also help on integration of firmware patcher into rbutil (C++ & Qt4), and work on the manual (I already started for the Fuze & the Clip, so it's relatively easy)
13:03:30funmanpixelma: by the way, most of the front device svgs in the manual look like they were made on your computer : can you draw pictures for Fuze and Clip ? (e200v2, m200v4, c200v2 can use their predecessors images)

18:52:57AndrewRBhey, just curious, as I don't understand much of the hardware in my DAP... Why do we need an ADC to read button presses?
18:55:23n1swell, afaiu that is one common hookup, they can also be hooked directly to a GPIO in which case you don't need an adc
18:57:22n1snot quite certain that i understand the adc kind of button reading but i suppose they could use a resistor network for example and read the resistance with the adc
18:57:45AndrewRBright. ok. GPIO is just another acronym to me (...scurries off to google). ah, ok. It's just that from reading the target-specific button code for my D2, it looks like to read a button press we are reading an ADC, and I was wondering how button presses could be an analogue signal
18:58:16 Join miepchen^schla [0] (n=miepel@p579ECE9F.dip.t-dialin.net)
18:59:17AndrewRBtrue, I guess that is possible. but somehow given that the buttons in my D2 are the usual type in portable devices like DAPs - small, press-to-contact, soldered directly onto the PCB, I doubt it. It just stumped me =/

18:59:47AndrewRBthanks anyways =)
19:00
19:00:41TorneAndrewRB: using a resistor network might save pins, is the usual reason, i think
19:00:55Tornenot all SoCs have loads of spare GPIOs once you've hooked up everythnig else
19:01:15Torneif you arrange such that each button cuts in different valued resistors you only need one ADC pin to read a whole bunch of buttons
19:01:42AndrewRBSure, op-amp. That helps me understand. thanks.
19:04:21Tornethere's never enough GPIO pins, from experience designing stuff :)
19:04:55AndrewRBpins require more space on PCB, I guess.
19:04:55Torneonce you turn on all the peripherals you need, and connect GPIOs for mandatory stuff like resets and so on, you never have enough for the actual general purpose stuff
19:04:58Torneindeed
19:05:16AndrewRBwho said size doesn't matter ;-)

19:05:57Torneit's more the space to route the damn wires than for the actual pins, though :)

19:14:00kugelwith 60MHz pclk or async?
19:14:34kugelit seems that pclk is so critical for decoding, that we really should try to run it at 65MHz
19:15:46kugelfunman: with that 10h I'm much below svn runtime even though it boosts less
19:16:14kugelwe could try to reduce pclk when unboosted, but that leads to more boosting again :S
19:16:30funmanwhen unboosted we also need decent graphic performance
19:17:17kugelwe could microboost in lcd_update(_rect)() (just going to 65MHz, keeping fastbus)
19:17:52*domonoky thinks we should concentrate on having stable clock settings, improving battery runtime can always be done later...
19:17:56funmanis there a time penalty when switching ?

19:35:31domonokyback to the asynchronus/synchronus issue. its probably without time penalty, as going from fastbus -> synchronus, probably only enables a buffer register (flipflops) between the two busses. and asynchronus add a bit of clock logic...

19:42:27kugelmaximal speed as in? maxing cpu clock or pclk?
19:42:35funmanboosted cpu clock
19:43:12kugelwe need async then. from what I've noticed, 248MHz async is *slower* than 192 sync
19:43:36funmanhum ok
19:43:45funmanthen why not using 248/62 ?
19:45:00kugelbecause 64MHz is already much faster than 62MHz from what I've noticed (I have 90MHz with 64 vs 115 with 62 in the view buffering screen)
19:45:44kugelI really slap AMS for capping the cpu to 250, and not *slightly* higher, like 265
19:46:00funman^^
19:46:15kugelbut apparently, the boosting rate is meaningless anyway, as I get less runtime with less boosting
19:46:31funmandid you check test_codec ?
19:47:54kugelnot with 62
19:47:59funmancalculation in buffering thread debug screen doesn't seem very precise
19:48:17funmanit counts how much ticks happen boosted or unboosted it seems
19:48:36kugelhm
19:49:11kugelbut it would be at least equally incorrect for 64 and 62, not?
19:49:30funmanit would be equally not significative at all for 64 and 62
19:49:48kugel:)
19:50:56kugelfunman: also, as I said, I'd be fine with microboosting for ata/dbop
19:51:32funmankugel: ok, if you test lcd, ata, battery, and codec performance
19:51:59kugelwhy me? :(((
19:52:08funmanyou've got test_disk test_codec test_codec and battery_bench for it
19:52:18funmanwell you can also put that on MrSomeone todo list :)
19:52:28kugelthose tools are yours too
19:52:36funmani'm hacking EDA now

19:53:03funmanalso i don't think using lower pclk clock is useful at this time
19:53:07funmanEmbedded DisAssembler
19:53:10kugelthat's seems a dangerous area ;)
19:53:16kugeloh, boring :p
19:53:20funmanyes, C++ :(
19:57:41kugelfunman: I figured from my bench that maxing pclk all the time gives less runtime no matter of the performance
19:57:55kugel(compared to your benches)
19:58:38funmani understand that higher frequency gives less runtime, but what do you mean about performance ?
19:58:56kugelhigher pclk gives better overall performance
19:59:11funmanok, so what's your conclusion ?
19:59:15kugeland the better performance doesn't seem to pay of w.r.t to less boosting
19:59:20kugeloff*
20:00
20:02:08funmanso do you think we should rather have long runtime and bit poor lcd performance for example, rather than good performance with shorter runtime ? (something in the middle, i.e. pclk a bit lower than the maximal value we use now)
20:02:41kugelI'm only talking about unboosted state
20:02:50kugeland yes, I think we want to maximize runtime
20:04:37 Quit einhirn ("Miranda IM! Smaller, Faster, Easier. http://miranda-im.org")
20:04:39funmanwe should make a difference between boosted cpu (for maximal _calculation_ speed) and boosted pclk (for maximal _peripherals_ (lcd, ata, usb, memory) speed)
20:05:02kugelthat would be microboosting then
20:05:24kugelfor ata,lcd,usb, I don't know if it will be doable for memory
20:05:38funmannot really :')
20:06:08kugelmemory doesn't really need max pclk imo
20:06:23funmanyou can post your suggestion on the forum with a patch, and ask for testers
20:06:35funmankugel: well data transfers will be slower then
20:06:51kugelsure, but the rest is slow too

20:07:32kugelI mean, I don't think ram access/read/write is slow enough to limit the cpu (which is on 32.5MHz too then)

20:08:08funmanright
20:08:28kugelunaligned ata transfers count into microboosting for ata, doesn't it?
20:08:55kugelI was thinking to do the microboost in sd_enable, which would then last as long as the whole transfer is active
20:09:48*domonoky would suggest to leave such microboosting things for later.. :-)
20:10:46kugelFlynDice: btw, why are you so opposed to split up your boosting scheme work into 1 change per patch?
20:10:52funmanperhaps "later", when we have caching on the AMS, we would then see that using 31MHz pclk is fast enough for decent performance
20:11:21kugelI mean, I'd like to see something that makes dev's lifes easier in SVN too. but if it creates breakage, we can't know what of the several changes caused it
20:12:21kugelif the CPU gets faster with caches, the slow periphery will limit / slow it down even more than without caches
20:12:37FlynDicekugel: I'm not opposed to it I'm just not sure how to do it.....
20:13:35FlynDiceI just made a tool to use without actually thinking it would be considered to go into svn....
20:13:55funmankugel: last patch looks OK (doesn't change the clocking scheme), if you approve it please commit

20:29:04bertrikThe fuze LCD driver seems to not really use the FIFO capability of the DBOP, I think it can get quite a bit faster with FIFO
20:29:21kugelhm, how?
20:30:18bertrikby trying to keep the FIFO full rather than empty in the data write loop in lcd_write_data (this function takes most of the bandwidth I presume)
20:30:40kugelhow big is the fifo?
20:30:52bertrikso instead of checking the empty bit, check for the almost full bit
20:31:15JdGordon|AndrewRB: I dont know what your skill level is.. but if you want something fun to do with the touchscreens... have a look at my email to the dev ml last week...

20:32:23kugelyou mean writing 1byte at a time is faster than 2, just so that the fifo doesn't empty?

22:34:38kugelit's full - 2bytes, right?
22:35:20kugelI think we should wait for almost empty, then start the loop again. at the end wait for empty
22:35:30funmanthere is fifo half full, fifo full, fifo empty interrupts for MMC/SD controller

22:35:50funmanor do you mean 'x' as in user-configurable?

23:02:23kugelyou can also flag functions as volatile, right?
