10:41:02gevaertsok :)
10:41:18Zagorat least if we want to use the same clients
10:41:35Zagora completely separate farm isn't that much work
10:42:30gevaertsThe main problem I see is that we'd need to remember to switch to another branch every major release

11:06:56CIA-7New commit by 03stummi (r28654): thanks for admitting me to the team :)
11:07:13marinesi've just received package with sansa c250... v2
11:07:22Stummimarines, 132 people can be "somebody" :)
11:08:06marinesnot in every channel ;]
11:08:19marinesdoes anybody use this player with rockbox?
11:08:29Stummii am using an fuze
11:08:45marinesi'm not sure if it is stable enough to use v2 version
11:08:46ZagorI have several c200s
11:08:55CIA-7r28654 build result: All green
11:09:01Zagorah, not the v2 though
11:09:08marinesyeah
11:09:13marinesthat's the problem
11:09:19marinesv1 worked great
11:09:22pixelmathe c200v2 doesn't seem to be used very often. As far as I know, it's a little "behind" the other AMS Sansa ports
11:10:00marinesrbutil doesn't autorecognize this player
11:10:51gevaertsmarines: are you using the latest version of rbutil?
11:10:57gevaertse200v2 should just work
11:11:08marinesi've downloaded it a second ago
11:11:15gevaertsStummi: welcome!
11:11:23Zagorgevaerts: c200, not e200
11:11:33gevaertsoh, right
11:11:39Stummigevaerts, thanks
11:11:53gevaertsyes, c200v2 isn't fully stable yet
11:13:09pixelmathe DeviceDetection in the wiki has no USB PIDs/VIDs for the c200v2 so I guess that's just not implemented in the Rockbox Utility either
11:14:09Stummiat first a question as commiter: When I have seval changes here bzw want to add serval features one time, i shouldn't do this with one commit but with serval commits (one for each feature), is this right?
11:14:20gevaertsStummi: preferably, yes
11:14:41Stummiok
11:14:49marinesi'll try svn build of rbutil
11:15:18gevaertsmarines: I suspect you'll be better off trying the manual install

11:42:40marinesi don't know if it's permanent setting
11:43:04marinesi've done lsusb after player reboot
11:43:46Zagorsounds like ums/msc then. can you do the same in mtp mode and see what you get?
11:44:19marinesthe process is the same?
11:44:38Zagorboot the OF, set it to mtp mode. plug in usb, run lsusb.
11:47:44marineskind off kernel panic i guess :>
11:47:53marinessandisk splash screen doesn't go off
11:49:01marinesoh, works, i ejected memory card
11:49:34marinesbut there is not such setting like usb mode
11:52:14marinesid changed
11:52:21marinesID 0781:7453 SanDisk Corp.
11:52:38marinesafter following usb mode change instructions
11:53:07Zagorso 7453 is mtp?
11:53:39Zagornearly all other sansas have mtp on the lower id
11:55:00Zagoryou can run lsusb -v and look for "bInterfaceClass 8 Mass Storage"
11:55:02marinesinstructions tell about changing mode to MSC
11:59:53marinesfor 0781:7452 there is "bInterfaceClass 8 Mass Storage" entry

12:23:40PurlingNayukiWhich two?
12:23:55marinesmtp and msc
12:24:00Stummimarines, in msc the device appears as an normal volume
12:24:23Stummiin mtp it uses a special protokoll for file transfert

13:08:49LambdaCalculus37The Neomagic Mimagic 3 NMS7210 SoC is an ARM720T. Wonder how performance will be...

13:10:49n1sLambdaCalculus37: wow, that's without the "fast" multiplier then?
13:12:09LambdaCalculus37n1s: Want the datasheet?
13:12:46n1sok, is that in Gigabeat MEG50JS?
13:12:56LambdaCalculus37Yup.
13:13:31n1sah, are you planning a port?
13:13:44LambdaCalculus37Some of the specs on the datasheet: "32-bit ARM V4T instruction set with 16-bit instructions (THUMB), 8KB four-way set-associative unified cache, MMU with 64 entry TLB, up to 110MHz in Asynchronous Mode"
13:14:10LambdaCalculus37n1s: toffe82 gave me one, and I had been looking at a firmware update to see how to get firmware on the device.
13:14:32n1swell, at least it has a cache :)
13:14:33LambdaCalculus37n1s: It's pretty interesting, because the entire firmware update is a tiny Linux system.
13:14:53n1swhat kind of clock frequency does it run at?
13:15:08LambdaCalculus37n1s: According to the datasheet, it can clock up to 110MHz.
13:17:11 Join TheSeven [0] (~TheSeven@rockbox/developer/TheSeven)
13:17:18LambdaCalculus37n1s: It can do dynamic frequency switching, at 18/36/74 MHz in synchronous CPU mode and 110 MHz in asynchronous mode.
13:19:03n1si think i'm wrong and that core is arm7tdm so it has the "fast" multiplier
13:20:06n1ssould be similar performance to a PP then i think

13:24:39n1shmm, it has a "write buffer" that sounds like it would help somewhat
13:27:51LambdaCalculus37n1s: Seems that it only has a 16MB buffer.
13:30:59n1s16MB of ram should be enough, a number of our old coldfire targets get by with 16MB
13:32:15n1safter reading a bit the arm720T seems nice, basically an arm7tdmi with cache, mmu and the write buffer, i had forgotten that the standard arm7ydmi doesn't have a cache (but the PP cores do)
13:32:41n1sLambdaCalculus37: do you have sorce for the linux firmware?

17:58:04gevaertsAnd usb_slave_mode() is implemented for both the hardware USB mode as for the usb stack mode
17:58:06pamaurythen it could be a good idea if all handles are properly released on usb connection
17:58:45gevaertsThey should be, but enforcing this via unmount is probably a good idea

19:05:07gevaertskugel: a filesystem with actual useful content (from our point of view) that's mounted (not just symlinked) in more than one place without user intervention sounds pretty unlikely
19:05:32kugelfrom that point of view you shouldn't start in / :)

19:05:46gevaertshuh?
19:06:03kugelon RaaA
19:06:15pamaury starting in / sound a bit akward, you will scan lots of unecessary files on RaaA, giving a speed penalty
19:06:22*gevaerts doesn't follow
19:06:41kugelpamaury: it was faster on my phone than scanning on my daps
19:06:59kugelbut it was "only" 26k objects to scan
19:07:07kugelon a pc it's more I guess
19:07:24kugelgevaerts: / has no useful content for rockbox
19:07:25pamauryon a pc you can easily have 100k objects
19:07:32kugelbut it has recursive symlinks
19:07:36gevaertskugel: yes, and?
19:08:03pamaurythus it is stupid to start the scan search in /
19:08:03gevaertsThat means there is a filesystem somewhere that does have useful content
19:08:21kugelare you talking about loops or multiple entries?
19:08:35gevaertsWhat I'm saying is that *that* filesystem won't be mounted multiple times, unless the system is owned by someone who's trying to break things
19:08:54kugelcyanogenmod mounts the sdcard twice
19:08:59gevaertsSo you won't find the same content twice if you don't follow symlinks
19:09:01gevaerts*why*?
19:09:05kugeldon't ask me
19:09:17kugelwell, it's not mounted twice, but /sdcard links to /mnt/sdcard
19:09:25gevaertssymlink?
19:09:32kugelyes
19:09:33pamaurythat's different and quite common
19:09:39gevaertsok, so what I'm saying still applies
19:09:41kugelso yes, I had multiple entries without user intervention
19:09:46gevaertsno
19:09:49gevaertsIt has symlinks
19:09:52gevaertsThat's different
19:10:24gevaertsSo the problem at hand is how to avoid cycles if people do stupid things with symlinks
19:10:33kugelyes
19:10:49gevaertsAnd if possible also to avoid multiple entries for the same file
19:10:56kugelI don't worry about FSes mounted multiple times, in fact I didn't even think about that until now
19:10:57pamauryyou need to mark objects or keep them in memory/db
19:11:41pamaurya nasty way would be to "touch" symlink

19:12:50gevaertshm

19:13:12gevaertsWhat if you *only* follow symlinks that point outside your (configured) search root?
19:13:38pamauryit won't avoid redundant entries
19:13:51pamaurybut will avoid cycles
19:13:56pamauryerr no
19:14:00pamaurymy mistake
19:14:37gevaertsWhat if you *only* follow symlinks that point outside your (configured) search root(s), and whenever you do that you add the target of that symlink to your list of search roots?
19:15:18gevaertsIf your search root is /, that means "don't follow symlinks"
19:15:31pamaurythis way you process at most each file twice
19:16:02gevaertsin which cases?
19:16:14pamaury"if you *only* follow symlinks that point outside your (configured) search root(s), and whenever you do that you add the target of that symlink to your list of search roots?"
19:16:22kugelgevaerts: that would work I guess
19:16:29pamauryyes might work
19:17:21kugelwhat if the targets have recursive links in them again?
19:17:44gevaertsThen they'd point back to one of the search roots, at which point you stop
19:18:20pamauryHum, you might process files more than twice in fact, but a finite number of times :)
19:18:30 Join marines [0] (~marines@marvin.uplink.cz)
19:18:52kugelgevaerts: they would?
19:19:34gevaertsIf you have /a/b/c/d -> /e/f, and /e/f/g-> /a/b, and you start in /a, you add /e/f to your search roots (which now are /a,/e/f), then you see /e/f/g which points to /a/b which is inside /a so you ignore it
19:19:36pamaurykugel: if you mark the target of a symlink, since there is a finite number of symlinks, there is a finite amount of targets, you at some points will have marked then all
19:20:47gevaertspamaury: the only ways I see to add a file more than once still involve somewhat interesting symlinking
19:20:53kugelah you add the outside targets to the search roots

19:21:39kugelsounds good, I can't see a disadvantage right now
19:22:02gevaertsI'd only do that if those targets are directories, in which case symlinks to files can still provide duplicates
19:22:25kugeloh, except you can still get duplicates
19:22:35gevaertsI think that if you also add all files that get pointed at, you might get a huge list of search roots
19:22:42pamauryit will be really hard to eliminate duplicates
19:22:45 Join DerPapst [0] (~Alexander@p5DE5BA72.dip.t-dialin.net)
19:22:56gevaertsYou can *always* get duplicates if you're creative enough
19:23:00kugelif /sdcard/ points to /mnt/sdcard, then it'd scan /sdcard/* and the /mnt/sdcard/* no?
19:23:02pamaurythere aren't so many symlinks I think
19:23:19pamaury(ot directories I mean)
19:23:22pamaury*ti
19:23:24pamaury*to :)
19:23:27gevaertskugel: only if /sdcard or /mnt/sdcard is the search root, and you have a symlink to the other *inside* the first
19:23:58gevaertsIf / is your search root, you'll ignore /sdcard (because it points to a target inside /)
19:24:15factorcool fuze has line out enabled in the 3.7
19:24:40gevaertsAnd if people have /mnt/sdcard/something pointing to /sdcard, I'd say bad luck

19:25:48*DerPapst did that once. was fun :)
19:26:23kugelok, it should work
19:26:51kugelyou don't follow symlinks, but instead you add the targets to the search roots if they're outside
19:27:15kugel(that's how I understand it now)
19:27:16gevaertsThis solution avoids cycles and I think it probably avoids all duplicates caused by symlinks set up by the distribution (or manufacturer), and caused by *most* symlinks set up by the user
19:28:00gevaertskugel: yes
19:29:09kugelI think that could work, and shouldn't even be too hard to implement
19:29:30gevaertsIf the symlink points to a directory at least. If it points to a file inside the search tree I'd say ignore as usual, and if it points to a file outside the search tree I'd include that file
19:29:52gevaertsBut not add it to the search roots, to avoid ending up with thousands of search roots
19:30:37gevaertsThe case I'm thinking of is people who set up all sorts of database-like result sets using symlinks
19:31:39gevaertshm

20:37:42n1smost codecs that have a lot of code in iram don't fit in iram when built with O3 with gcc 4.4 since the code usually gets much bigger
20:38:37Buscheln1s: from what I saw (on ARM) -O3 was seldom faster as -O2. and if it was faster, it was only a minor speed change

20:42:37n1sit's about 2-3% for vorbis so if i don't find something that closes it further i think i'll just live with it as the new compiler speeds up other codecs IIRC (will need to rerun that benchmark some day)

23:17:26CIA-7New commit by 03bertrik (r28662): Sansa c200/c200v2: limit allowable contrast value to 0-127, it wraps at 128.
23:17:45TheSevendoes anyone want to join my ipod classic efforts, especially reversing the hdd driver?
23:17:51TheSevenideally someone who has dealt with MMC before
23:18:37gevaertsTheSeven: is it all MMC?
23:18:45TheSevenapparently
23:18:50bertrikDoesn't amiconn know about MMC?
23:19:02TheSeveni see loads of mmc/ce-ata, and i haven't seen any traces of regular PATA yet
23:19:16CIA-7r28662 build result: All green
23:19:22TheSevenand the code is full of debug_printf() calls in various error conditions :)
23:19:52gevaertsMaybe the PATA code worked the first time? :)
23:20:41TheSevenjust some examples:
23:20:42TheSeven"mI: SET_RELATIVE_ADDRESS failed\n"
23:20:53TheSeven"mC: timed out waiting for DSTA_RESEND\n"
23:21:20 Quit TheLemonMan (Quit: Help me, i got shot! *DIES*)

23:22:32TheSeven"cI: Set drive to MMC high speed failed\n"
23:22:50TheSeven"cI: CE-ATA signature missing (%x,%x)\n"
23:22:58amiconnThe Ondio uses MMC, but in SPI mode
23:23:08amiconnThat's somewhat different from MMC mode
23:23:38TheSevenonce we figure out which register bit is what, things should be rather easy
23:24:01amiconn(the bridge uses it in MMC mode, but there's nothing to do for us except enabling the bridge (and clocks) with some GPIOs)
23:25:24TheSevenand if I see something like sub_8009380(0x230041, 0xFF8000, NULL, hdd_driver.command_timeout), I'm pretty sure that the lower bits of the first arg are the MMC command number. but what's the rest?
23:25:46TheSeventhe 0x30000 bits seem to be related to the response to be expected
23:25:54TheSeven0x200000 is almost always set
23:26:07TheSeventhe first argument is directly written into some register of the MMC controller

23:29:52bertrikOP COND is also an SD command to ask for capabilities of SD cards IIRC (e.g. supported voltage range)
23:30:43TheSevenyes, and it's command ID 0x01 (for MMC at least), matching the first argument
23:31:07TheSeventhere are also lots of similar calls with different commands
