00:06:18wodzfunman: to speedup testing You can increase log rate in powermgmt.c
00:08:47funmani changed 60*HZ to just HZ line 690, is that enough?

00:18:52wodzyes like gnuplot can do for example
00:19:18wodzit is easier to see abolute values than
00:19:40funmanare values really important? i use this screen to see if it's increasing or decreasing
00:20:52wodzbecause it is autoscaled I would like to see at first glance if values changes much or only slightly
00:21:14 Join Soap_Hotel [0] (
00:21:37funmanperhaps just make the grid 1pixel and the line wider
00:22:33wodzmaking line wider is not so easy I am afraid
00:24:12wodzbut maybe ploting copy of the curve shifted 1px down will be enough

03:19:54Rob2223well i asked a third person with the problem

03:20:08CIA-5New commit by bieber (r26400): Themeditor: Got the ParseTreeNode class in good shape, preparing to start on ParseTreeModel
03:21:07saratogayour best bet is probably to figure out what changed in the firmware files
03:21:28Rob2223thats just not easy
03:21:32Rob2223a already tried
03:21:36saratogayes but its actually useful
03:22:05saratogaeven if the serial numbers do mean something its not clear to me how that helps at all
03:22:36Rob2223when i return my brand new player i would like to get a player that accepts RB in the 2nd try
03:22:51Rob2223i only bought it for RB so i will retuen it in 10 days

03:24:13bieberIf you stick a skin_debug_tree(test) in main.cpp it'll give you the ASCII debug info

03:26:38JdGordonalso did you see my qeustion last night?
03:27:22bieberThe one about using skin instead of WPS?
03:27:43bieberYeah, I'm pretty sure that's taken care of now
03:27:53bieberIt was just in ParseTreeModel.h/cpp, right?
03:27:55JdGordongreat :)
03:28:11JdGordonpossibly, I saw it in one of the .h's
03:28:22bieberOkay, it should be clear

03:29:12 Quit merbanan (Read error: Operation timed out)
03:30:52Rob2223saratoga: I fear that the new check has something to do with the hardware or some code that is already in the players. Cause the same .33 files working for some players and for some they dont :(
03:31:37bieberThanks, got it
03:33:14saratogaRob2223: maybe the update depends on some code on the AMS ROM, and that got updated in newer players
03:34:44saratogathey might have run out of the original run of AMS chips and had to order another batch or something from the fab
03:35:59Rob2223and they tooks the chance for a rom upgrade?!
03:36:19Rob2223do you know if the AMS rom is used by the player?
03:37:51saratogai assume its used to load the firmware file off the flash memory
03:38:12saratogatheres no other memory on the device, so i don't know what else could load the firmware
03:38:35Rob2223are there not files on a hidden partition?
03:39:14 Join moparx [0] (~moparx@unaffiliated/moparx)
03:39:18Rob2223i mean is the original firmware from a firmware upgrade file the only data in the hidden space?!
03:39:38Rob2223i didnt found any information about that
03:40:37saratoganone of this is in a partition
03:40:47saratogathe ROM is memory mapped
03:41:15saratogathe as3525 datasheet explains how it works on the fuze/clipv1, probably not much different on the clip+
03:41:19Rob2223well ok, maybe bad word coice from me. the area to where the file is flashed at the firmware upgrade process
03:41:50Rob2223couldnt there be other files/data?
03:42:21Rob2223yeah i think i know the memory mapped procedure
03:43:04Rob2223i thought the firmware is flashed onto a hidden part of the 2GB memory
03:43:18Rob2223is it flashed into the SOC rom?
03:43:41saratogaas I said above, its loaded from the NAND
03:44:35saratogaunless the NAND can be memory mapped, its probably copied into RAM by whatever code is already on the ROM
03:45:09Rob2223so the nand is the 2gb/4gb/8gb chip, right?
03:45:24saratogayes, NAND is a type of flash memory
03:46:02Rob2223so the firmware upgrade copies the fusp.bin forom the fat partinioned part of the NAD to another area of the nand thats not in the FAT partition
03:46:24Rob2223(sorry for my grammar, im already damn tired)
03:46:44Rob2223to at the hidden place of the nand could be some more information
03:47:09 Join Blue_Dude [0] (~chatzilla@rockbox/developer/Blue-Dude)
03:47:17Rob2223or maybe even the firmware upgrade routine could be thare and it did never get touched by the firmware upgrade process
03:47:23saratogaAFAIK the hidden part is a verbatim copy of the firmware bin, at least on the V1 players
03:47:32saratoganot sure if anyone ever dumped it on the newer devices
03:47:37CIA-5New commit by bieber (r26401): Theme Editor: Got a barely functional treeview in place
03:47:53JdGordonbieber: at a high level, how does the parse tree get new branches?
03:48:12JdGordonor, whats the breakdown?
03:48:17bieberJdGordon: Okay, now it displays the file in a treeview. The formatting sucks atm, but that'll get better when I have some more time to work on it
03:48:48Blue_DudeS_a_i_n_t: Sorry, I haven't even tried to do a eabi toolchain on Cygwin. I guess it's possible but I just have a "stock" install. Well, I also added Python for analysis scripts, but the rest is standard.
03:48:48bieberAt the highest level, everything gets broken down into either a SUBLINES branch or a LINE branch
03:48:58Rob2223if that were for the V2, too, then the code that rejects newer firmware must be in the .33 firmware upgrade anywhere.
03:49:42Blue_DudeS_a_i_n_t: for that matter I'm not really sure what eabi is, so I'm probably not the guy to ask. :)
03:49:51bieberAlso, while looking over the stuff from the treeview, I just noticed another bug in my parser. Apparently when scanning for sublines, it's stopping any time it encounters a newline, even if it's at the end of a comment
03:49:53Rob2223saratoga: my only ida atm would be disassemble the FW and trying to analyze it but even if i am able to read assembler i dont think that i will find that part :(
03:50:06JdGordonbieber: ok, viewports actually need to be the hieghest level
03:50:41saratogai think comparing the firmware files is probably easier
03:50:42JdGordonis that going to be difficult without giving the parser too much knowledge about what a viewport is?
03:50:56saratogaif you figure out whats different it doesn't matter how the firmware update is implemented
03:51:38bieberThat would really be beyond the realm of the parser, since at that point you're dividing things up according to the way the renderer will interpret it, rather than just the semantic structure of the document
03:51:40JdGordonbieber: also (a request only) can #( and #) or )# be added for multi line comments?
03:52:01bieberMulti-line comments will be easy
03:52:18Rob2223saratoga: the problem is from .28/.31 to .33 are many differences in the firmware file.
03:52:45 Quit Blue_Dude (Quit: ChatZilla 0.9.86 [Firefox 3.6.3/20100401080539])
03:52:52saratogayes but you only care about changes to the header
03:53:13JdGordonbieber: I'd still argue that the document structure goes viewport > line > subline
03:53:17saratogaremove the firmware bits and compare whats left
03:53:26JdGordonmaybe it is not obvious because the defualt viewport isnt put into the document
03:53:54bieberSo %V tags can never be conditional, and they can always be viewed as marking a new section of the document?
03:54:31JdGordonyes, but that include %Vi and %Vl... maybe add a char to the param list saying "start a new top level node"?
03:54:41Rob2223saratoga: theres no change in the header to 0x400 but the checksums :(
03:55:05bieberJdGordon: If it's just those three cases, I can hardcode it easy enough
03:55:27JdGordonthat would work also :) I was just thinking more for keeping the parser very generic
03:55:44Rob2223saratoga: have .31 to 33. open on right screen and .28 to .33 open on left screen. i already compared the header today
03:56:52CIA-5New commit by bieber (r26402): Theme Editor: Fixed parsing bug that allowed comments to form a new logical line in a skin document
03:57:15saratogaRob2223: did you try dumping firmware libraries and looking at whatever was left?
03:57:29saratogaperhaps theres more to the header then just the first 0x400 bytes
03:58:00saratogasince older players can still take this upgrade files, i assume the header didn't change much, but that doesn't mean they didn't add another header somewhere further back
03:58:05Rob2223is there a tool for?
03:58:14Rob2223i just compared the .bin binary
03:58:23saratogayou haven't actually dumped one of the bin files?
03:59:10bieberJdGordon: I'll have it divide documents up by viewports whenever I have a chance to code some more, it shouldn't take me long
03:59:11Rob2223no i compared the fuzpa.bins

04:00:08Rob2223saratoga: you didnt have a compiled win26/64 version at hand, or?
04:00:11saratogayou'll probably want to look at the amsinfo tool's parser to get a feel for how the file works
04:00:57Rob2223yeah, good idea. i read all i could found until now
04:01:36Rob2223saratoga: have you a compiler chain set up?
04:01:53saratogai don't know how to compile stuff for windows, and since you'll have to change the code anyway i'm not sure how much use a binary would be
04:02:12JdGordonbieber: sweet, and please remember to add the default node so if the first non comment isnt %V it will still work as expected

05:02:19JdGordonthe extra info will make tag_table.c more annoying for you, but if a tag is ever added or changed it means only fiddling with one place to make the changed tag acpeted everywhere
05:07:22JdGordonthis is even ignoring the fact that some tags are target dependant...which I guess makes perfect sense to keep ignorin

16:10:19AbaojiHi everyone, I have a Sansa E200 series running most current version of Rockbox. I know Rockbox has dual-boot function. I wondering if it's possible to permanently disable manufacturer's firmware[i.e. Sansa] and use Rockbox as default firmware.
16:12:04JdGordonyou can, but it is not advisable...
16:12:10JdGordonI accidently did it to mine :p
16:12:15JdGordonjust ignore the OF
16:12:46AbaojiI want to disable the manufacturer's firmware because I bought a new FM transmitter and everytime when I when turn off the player, Rockbox won't be able to load.
16:13:12AbaojiJdGrodon: How to disable?

16:31:13gevaertskugel: are you just converting the #ifdefs mostly blindly, or are you also checking if the ifdefs actually make sense, and if they e.g. should be handled differently for RaaA and the sim?
16:31:16bertrikI'm getting compiler warnings trying to get the samsung yp-s3 bootloader to build, it complains about format expecting 'unsigned int' but argument having type 'long unsigned int'. The argument is a uint32_t defined in stdint.h
16:31:52bertrikWhy is uint32_t defined as 'unsigned long' instead of simply 'unsigned int'?
16:33:08kugelgevaerts: the latter
16:33:26funmanbertrik: both are 32 bits, so any will do
16:33:30bertrik(this is for sprintf)
16:33:33kugelI left some #ifdef SIMULATOR as is, for instance those which are for debugging purpose only
16:34:35bertrikfunman, yes I know they are for our targets, but the compiler thinks they are different. Somehow a decision was made to make it explicitly 'long'
16:35:00funmanthe sizes are the same, the types are different
16:35:03 Quit orzech (Quit: leaving)
16:35:23funmanprinting a uint32_t requires special format strings usually, like PRId32
16:35:40kugelgevaerts: basically, those that are relevant for RaaA are converted, the others not
16:36:00funmanbut we don't have these defines in rockbox, so you can just cast it to anything, that's what other parts of rockbox do already
16:36:05gevaertskugel: probably out of scope for RaaA, but I think some of the ifdefs shouldn't be there for the sim at all, like e.g. battery_voltage in plugin.c. It's probably useful to ask MrSomeone to review the things again later on for that :)

16:44:10bertrikfunman, really? uint32_t would still fit in an unsigned int on most (if not all) targets. I don't see the need for a long, I notice only disadvantages
16:45:40funmanthere's no difference between long and int on our 32 bits targets, except that the C language treats them differently, and so *printf need different format specifiers
16:45:46funmanint isn't better, or worse, than long
16:46:07funmanit's just a different type, but since they have the same size you are free to cast them to each other

16:54:39funmanwe can change memory voltage from 1.8V to 1.7V on as3525v1, it seems OF does that
16:56:48gevaertskugel: have a look at e.g. apps/plugins/zxbox/spmain.c. Why on earth do those depend on !SIMULATOR?
16:57:50kugelexcellent question
16:58:17gevaertsMy guess is "possibly historical reasons"
16:59:25kugelshould I fix those most useless ones, ignore them or convert them?
17:01:03gevaertsI'd say ignore them. Anything else will make the eventual commit less clean
17:01:57kugelok, ignoring them possibly also shows how useless they are since RaaA doesn't define SIMULATOR
17:03:56funmanbertrik: gcc has a limits.h itself, are you sure it's not that one which is included?
17:06:31bertrikI'm not sure I understand any of this any longer, is there someone here who knows and can explain in simple words why we use longs for 32-bit units?

17:10:06*kugel thinks using int instead wouldn't hurt
17:12:14gevaertsJust inverting the order in stdint.h should achieve that

17:40:14kugelfunman: shouldn PTR be %(l)X?

20:08:55S_a_i_n_tthe GF uses iLoader in hers. I personally wouldn;t say that eaither is more stable than the other, iLoader just does more.

20:23:31saratoga_does the thumb patch simply ignore files with ASM blocks in them?
20:24:52funmansaratoga_: i posted 2 gcc frontends, the first runs preprocessor, remove unused static inline functions, and then just grep for 'asm' -> if there is no match the file is built with -mthumb, else with default (no thumb)
20:25:14funmanthe second one (both are .py scripts) just tries to build with -mthumb, and falls back to default only if it fails
20:25:34saratoga_funman: then thats why the codecs don't get slower
20:25:38funmanso if the asm is valid thumb assembler it will be built with thumb
20:25:40saratoga_they'll all have an ASM block
20:25:54funmanbut they use rockbox functions anyway?
20:25:55saratoga_for the fixed multiply code
20:26:13funmanand perhaps there is some c files in codecs which don't have asm
20:26:34saratoga_things like bitsream.c/h on the ffmpeg based codecs probably get smaller
20:26:50 Quit solexx (Quit: leaving)
20:27:10saratoga_but anything that does multiplication will have an ASM block, so all the core of each codec, if not all the helper functions
20:27:16funmanin the 2nd script youcan uncomment the secodn to last line so it shows files not built with thumb on stderr
20:27:31saratoga_do any codecs get much smaller?
20:27:49funmandidn't check any .rock or .codec
20:28:39saratoga_might be worth comparing to

20:35:46S_a_i_n_tOh, is that it? I guess with the drama I went through to build the toolchain I was expecting it to wash my dishes and do the vaccuuming ;)
20:36:24kugelS_a_i_n_t: some codecs run faster as well it makes it possible to remove a hack which adresses gcc's inability to make proper calls of static functions across memory sections
20:38:17S_a_i_n_tAwesome, if binsize was the only advantage I'd have a hard time seeing the point.
20:38:32S_a_i_n_tI'm glad there's more to it.
20:42:06funmanif you know how to alter shell $(()) precision please tell ^^
20:42:43saratoga_looks about right

21:17:03funmanwell perhaps not useless: you can load 100kB bigger files in test_codec ;)
21:17:14saratoga_the biggest codecs are wma and aac, and they're so big mostly because of enormous lookup tables
21:17:35saratoga_WMA has a 64KB random number table because I was too lazy to figure out how to shrink it :)

22:53:58funmanamiconn: which PP don't use lcd-as-memframe.S ?
22:54:34amiconnfunman: Many...
22:54:44funmanwodz: nice, you want me to test on clip?
22:54:50amiconnAfaik e200v1 is the only PP which does use it
22:54:57funmanamiconn: nice, e200v1 didn't boot when built with thumb
22:55:14funmanperhaps on other targets the lcd worsk before the undefined instruction
22:55:16amiconnI would expect such effects
22:55:33wodzfunman: fuze rather
22:55:57amiconnMany .S files return using ldm, which doesn't handle interworking on armv4t
22:56:29funmanamiconn: well supposedly the one in lcd-as-memframe.S was fixed in this build, many parts of the code don't handle interworking
22:56:51funmani'm checking them all and will post a patch on flyspray

23:06:25funmanamiconn: can you explain the 3rd line in thread.c::load_context() for ARM ? it was added in r14879 for dual core
23:06:45funman%0 points to start of thread context struct, which is the saved registers
23:07:12funmanldm %0 { r0, pc } will load saved r0 in r0 and saved r1 in pc <- why r1, and not [%0, #40] ?

23:26:28funmancan you explain the 3rd line in thread.c::load_context() for ARM ? it was added in r14879 for dual core
23:28:48jhMikeSit may have been optimized a bit, but I don't think it was changed to support it. It goes to start_thread.
23:29:38jhMikeSstart_thread calls the real entry as defined in create_thread
23:31:31jhMikeSif there were an issue there, I doubt rockbox would run on any ARM...but, what is the concern?
23:32:06jhMikeSsomething with thumb code?
23:32:19funmanit's how i came to this yes
23:32:26funmanthe 3 first lines are equivalent to:

23:43:00funmansame number of cycles
23:43:16CIA-5New commit by bertrik (r26417): Update Samsung YP-S3 bootloader demo
23:43:40jhMikeSbut, it can reduce the amount of instruction cache missed, maybe
23:43:46kugelfunman: but there's 1 instruction more, why is that free?
23:44:05funmankugel: ldm doesn't take same number of cycles if you load pc or not
23:44:19funmanjhMikeS: wouldn't it increase it, if functions are bigger?
23:44:22kugelah ok, I didn't know that
23:44:53jhMikeSfunman: that's what I meant, thumb could help a bit, even if the instructions are still they same cycle count
23:45:19funmanjhMikeS: ah for thumb, yes but the effect is small on the codecs
23:45:34jhMikeSloopy code?
23:45:37funmanthe patch works btw
23:45:59kugelfunman: do you think the e200v1 build is fixed with the new patch?
23:46:00jhMikeSlots of repetitive execution in the codecs
23:46:25funmanmore like important code is not built in thumb

23:49:03funmanARMv5 works too
23:49:28jhMikeSah, even ARMv5 does it right
23:50:03funmani'm not sure about mov pc, lr
23:50:18funmani've read that it works only on armv7
23:50:25jhMikeSprobably in the docs
23:50:35funmanbut we use that in nrv2e code for mkamsboot on armv4t and it works

23:52:29jhMikeSarmv6 docs say you have to use 'bx lr'
23:52:45amiconnjhMikeS: I've found a way to apply your nice optimisation in lcd-as-gray.S so that it works on mini2g as well
23:52:55funmanmov pc, lr restores the spsr into cpsr
23:53:02amiconnNo speedup there because the serial lcd i/f is the limiting factor
23:53:22jhMikeSamiconn: does it speed up the other at least?
23:53:32amiconnNo slowdown though, and less binsize. Also, smaller ifdefed code blocks in the .S file
23:54:02amiconnYes. On my G2, it reduces ISR load (without GREY_ON_COP) from 33% to 30%
