IRC log of #maemo for Sunday, 2012-10-07

kerioisn't it much faster than the emmc or the usd?00:00
DocScrutinizer05there's not more than 256MB NAND anyway00:00
DocScrutinizer05and no, it's not THAT much faster00:00
shamusif you ask my thats just crazy00:01
DocScrutinizer05you still need to flash-erase whole pages, which kills your swap00:01
teotwakishamus: what's the point, though?00:01
DocScrutinizer05and also regarding wear00:01
shamusim guessing they did it becasue they could00:02
shamusdo they realy need a reasion00:02
kerioDocScrutinizer05: would it be easier to replace the whole SoC?00:02
DocScrutinizer05waaaay easier00:02
keriocool, let's do that then00:02
teotwakihas anyone run Maemo on any other SoC than the n900?00:02
DocScrutinizer05we already had that topic finalized some 4 weeks ago00:02
DocScrutinizer05we just need an OMAP3430 with better specs and better OneNAND POP00:03
DocScrutinizer05and somebody uttered "palm pre"00:03
DocScrutinizer05as a possuble source for such a critter00:03
DocScrutinizer05but then, there's cert for xloader00:04
DocScrutinizer05so unless we get uBoot to properly boot maemo, we're probably still screwed00:05
shamusnow what would be funny/sad is somone trying to get Maemo to run on a palm Vx lol00:05
keriowould a 3630 work fine too?00:05
kerio(palm pre 2)00:05
DocScrutinizer05prolly not00:05
DocScrutinizer05I guess their electric specs don't match00:06
keriothe pre's is 500/600mhz like the n900's00:06
DocScrutinizer05uneducated guess00:06
keriothe pre plus has half a gb of ram, though00:06
*** m4g0g has left #maemo00:06
keriowhich would be ZOMGSOGOOD00:06
DocScrutinizer05kerio: download "datasheets" of omap3430 and 3630 from TI and check00:07
DocScrutinizer05if the pins are all the same names, odds are they could be just a drop-in replacement00:08
DocScrutinizer05if you find a devel board with chip socket, that claims to take both 3430 and 3630, then as well odds are good00:09

*** ced117 has joined #maemo00:09
DocScrutinizer05and *particularly* if you check kernel sources and there's no diff in noardconfig parameters for 3430 and 3630 boards, you could assume the peripherals are all the same, and thus maybe chips are compatible00:11
DocScrutinizer05board-config even00:11

jacekowskifreemangordon: only thing i don't like about it is the fact that there are thumb alternatives you are supposed to use instead00:24
jacekowskifreemangordon: because swp + 2 switches have HUGE penalty00:24
keriojacekowski: can't that code be written in C?00:26
jacekowskifreemangordon: swp and swpb is deprecated in arm600:26
teotwakiany code can be rewritten in C, doesn't mean it'll be faster.00:27
jacekowskikerio: not something like that00:27
keriowhy not00:27
*** bugzy has quit IRC00:27
jacekowskikerio: because it's thumb to arm switch and back to thumb for once00:27
*** bugzy has joined #maemo00:27
jacekowskikerio: and it's using swp instruction and you can't make gcc emit that instruction00:28
jacekowskifor two reasons00:28
jacekowskiit's deprecated00:28
jacekowskiand C has no understanding of mutexes00:28
*** raandoom has joined #maemo00:28
jacekowskiwhat SWP is doing is swapping two memory locations as one atomic operation00:29
*** uen has joined #maemo00:30
jacekowskithere are compiler specific ways of doing things00:30
jacekowskibut those use memory barriers00:31
jacekowskiwhich is the way it should have been done00:31
jacekowskiGCC is pretty shit00:32
keriodon't say that!00:32
jacekowskiit's decent on x8600:32
jacekowskibut other platforms, it makes me cry00:32
kerioi thought linaro wasn't that bad00:32
jacekowskilinaro has not much to do with gcc00:33
jacekowskionly platform where gcc generates acceptable code is x8600:34
jacekowskiand even then it's pretty bad when compared with ICC00:34
jacekowskionly "good" thing is, that MSVC is just as bad as gcc00:34
keriohow does clang compare?00:35
jacekowskiclang is bit strange thing to compare it directly00:35
kerioclang/llvm as a whole?00:35
keriono, i mean, how does it compare to clang/llvm as a whole? :)00:36
jacekowskiwell, it has improved a lot00:36
*** VDVsx has joined #maemo00:36
*** Pali has quit IRC00:37
keriowhich one? gcc or llvm?00:37
keriobut gcc is still better?00:37
jacekowskibut thing is, llvm has plenty of overheads00:37
kerioi'm talking about arm00:37
jacekowskidunno about arm00:37
jacekowskito be honest, there is no good all round compiler for arm00:38
jacekowskii've seen code generated by codesorcery00:38
jacekowskior codesomething00:38
jacekowskiand arm arm compiler00:38
jacekowskiand all had their problems00:38
jacekowskithough, arm compiler seemed to do least amount of fuck ups00:39
*** VDVsx has quit IRC00:41
freemangordonjacekowski: ldrex / strex won;t do the job00:41
freemangordonI am using 4.7.2 and can use sync intrinstics00:42
freemangordonbut they implement mutex by themselves, not MUTEX_SET00:42
jacekowskiyeah, well, ideally you would replace whole mutex implementation fully in thumb00:42
freemangordonand having in mind berkeley deb uses swp/b even in it's latest code, I don't dare to rewrite mutex implementation in such a critical databse00:43
jacekowskibut thing about bdb, in most cases there is no real need for mutexes in it00:43
infobotfreemangordon meant: and having in mind berkeley db uses swp/b even in it's latest code, I don't dare to rewrite mutex implementation in such a critical databse00:43
jacekowskiin mose use cases*00:43
freemangordonjacekowski: there is no penalty for going thumb/arm/thumb afaik00:44
jacekowskii'm pretty sure it causes pipeline flush00:44
freemangordonmost probably. but it is the same wuth gcc intrinstics, they put data memory barriers, i've already tried them00:45
freemangordonand used IDA to check the code after that00:45
jacekowskibut i think swp has higher penalty than mode switch00:46
*** brzys has quit IRC00:46
freemangordoni know I can write in assembly, as memory barriers are for luti-cpu, but still00:46
freemangordonmode shwitch should not have any penalty besides what bx does00:46
jacekowskibranch misprediction has pretty hefty penalty00:47
jacekowskiand normal running system you get very very high hitrate on that00:47
*** brzys has joined #maemo00:48
jacekowskibut branch misprediction means that full pipeline is thrown out00:48
jacekowskiand cortex-a8 has 13 stage pipeline00:48
freemangordonyou mean bx will flush the pipeline?00:48
freemangordonbut aiui there is no way to mispredict it, as it is always taken00:49
jacekowskiBX can have condition00:49
freemangordonand abyway BTB is flushed on every context switch :D:D:D00:49
*** ced117 has quit IRC00:50
freemangordonwell, it can, but it has not in the current code00:50
*** messerting has joined #maemo00:50
jacekowskiahm, you are talking about bx in your code00:50
jacekowskii though we are talking generally about bx00:50
freemangordoni am talking about my code00:51
jacekowskibut in your case it will cause flush00:51
freemangordonwill it?00:51
freemangordonbecause of swpb?00:51
jacekowskiit's just predicting location00:51
jacekowskino, because instruction decoder will be running in ARM mode00:51
freemangordonaah, i see00:51
jacekowskiso prefetched instructions will be decoded as arm00:51
freemangordonyes, you're right00:52
jacekowskiand then you switch to thumb and only then processor realises that it's decoded them wrong00:52
freemangordoncorrect. damn, i'll have to rewrite that with lrdex/strex00:52
jacekowskibut thing is, penalty on that is only part of it00:53
*** OkropNick has quit IRC00:53
jacekowskiswp is not penalty free as well00:53
jacekowskii'm not 100% sure if it's cached00:53
*** int_ua has quit IRC00:53
freemangordonyeah, but it is a legacy from the origoinal code00:53
freemangordonjacekowski: i'm convinced :D00:53
jacekowskiSWP causes processor wide bus lock00:54
jacekowskithough, on n900 with single core it doesn't matter so much00:54
freemangordonno matter that code will work in it's current form, I hate when developers do it in the easy (read ineffective)way00:55
jacekowskibut on multicore system it will stop all cores00:55
freemangordonyeah, i know that.hmm, actually i can rewrite that with only 3 instruction00:56
jacekowskiand may cause cache lines to be flushed00:56
freemangordonldrex,mov, strex00:56
freemangordonno memory barrier as we're on single core00:57
*** grayhat has joined #maemo00:57
jacekowskion x86 there is memory snooping for that, but i'm not sure how ARM implements that kind of stuff exactly00:57
freemangordonand I am not trying to upstream that :D00:57
grayhatHow can I reset n900 to factory default00:57
jacekowskigrayhat: flash it00:57
jacekowskisleep to do00:57
freemangordonjacekowski: ldrex/strex00:57
grayhatjacekowski: i dont know how to do that00:58
jacekowskifreemangordon: i'm talking hardware side00:58
infobotmethinks maemo-flashing is
jacekowskifreemangordon: as in what happens if one core updates memory location that is cached in another core00:58
freemangordonjacekowski: aah, ok00:58
freemangordonthere is cache protocol for that00:58
grayhatThanks y'all00:58
* freemangordon has forgotten the name00:59
jacekowskifreemangordon: on x86 all cores snoop memory accesses and will update or in some cases invalidate specific lines00:59

nox-oh well...02:18
entitled/proc/cpuinfo... in features the one im using daily has thumbee and the one in reserve does not?02:21
HurrianNothing currently uses ThumbEE. It's just a CPU feature seen by Linux.02:22
entitleddue to software I've installed 8 suppose, all should support thumbee02:22
entitledas it's the same armv7 revision02:23
*** VDVsx has joined #maemo02:23
HurrianAgain, it /supports/ ThumbEE, but nothing uses it02:24
entitledanyone replaced the digitizer on their n900? are all those chinese ones as good as any other?02:24
HurrianIt's for faster Java, but I don't recall even Android devices using it.02:24
Hurrianentitled, the chinese digitizers are crap.02:25
HurrianIIRC there was this one seller on eBay with surplus N900 ones, but I can't find it anymore.02:25

DocScrutinizer05re cpuinfo: what I find a tad concerning is the >>BogoMIPS        : 249.96<< on PK46 device, while stock kernel gives >>BogoMIPS        : 499.92<<02:50
DocScrutinizer05WTH?! the other one with stock kernel and CSSU-TH also has >>BogoMIPS        : 249.96<<02:52
DocScrutinizer05btw all three 210102:52
*** teotwaki has quit IRC03:04
DocScrutinizer05btw, on a sidenote:03:05
DocScrutinizer05t900:~# uptime03:05
DocScrutinizer05 02:03:09 up 190 days,  2:58, load average: 0.00, 0.00, 0.0003:05
DocScrutinizer05since I got other N900 for battery charging, I won't probably boot it that often anynore ;-D03:07
DocScrutinizer05so one thing I can confirm: WLAN driver, kernel, and sshd are rock solid ;-)03:08
GeneralAntillesI can hardly get through a day without having to reboot the N950 to get back lost modem connectivity.03:09
DocScrutinizer05no modem on t90003:10
DocScrutinizer05no SIM03:10
DocScrutinizer05or rather...03:10
GeneralAntillesI want a Jolla device. :<03:10
DocScrutinizer05a sim that's not valid anymore, and thus not registering03:10
HurrianDocScrutinizer05, measurements are taken at boot03:12
DocScrutinizer05dang, *#0000# shows "V 3.2010.02-8" on t90003:13
DocScrutinizer05Hurrian: :nod:03:13
DocScrutinizer05still doesn't explain it completely to me03:14
HurrianIf you edit /etc/pmconfig, you can get it to bump up.03:14
HurrianI think for some devices, it ramps up the CPU OPP earlier, and for some devices later, resulting in 250 and 500 MHz BOGOMIPS03:14
DocScrutinizer05yeah, but for both systems they run same kernel and same /etc/pmconfig03:15
DocScrutinizer05I wonder if one of them booted on battery while the other on charger03:16
*** hardaker has quit IRC03:16
*** Darkchaos2 has quit IRC03:20
DocScrutinizer05MEH, CSSU-TH comes with PK, no?03:21
HurrianA rebranded KP (the one on the newest -thumb comes with 51r1)03:22
DocScrutinizer05so, after testing the thumb device with booting from battery, this boils down to "on KP: BogoMIPS : 249.96.    On stock kernel: BogoMIPS : 499.92"03:23
SpeedEvildoes (say) md5sum /dev/zero go the same speed03:24

robbiethe1stYou can always reflash no matter how badly anything screws it up10:07
robbiethe1stu0boot fails? reflash10:07
robbiethe1stIt's got the flashing stub in the bootloader in a different rom chip10:08
kerioyeah, you can't really brick the n900, apart for hosing CAL10:09
keriorobbiethe1st: hi10:09
robbiethe1stAnd even then...10:09
keriorobbiethe1st: BM should really ignore the installed /etc/passwd10:09
keriobecause my login shell is bash10:10
kerioand there's no bash in the BM root10:10
robbiethe1stI think my next version or patch which I've nit released just adds a symlink to /bin/sh...10:11

kerioyeah, the "inner" symlink doesn't exist10:12
kerioaccording to busybox10:12
kerioyou could use a shell script, i guess10:13
robbiethe1sthm, yeah10:13

_PanzerSajtkerio, yes I know that we can't brick n900 but I don't want to reflash again and install all the softwares.10:13
robbiethe1stI just thought, however, that what I could do is check for the existance of that password-enable file10:13
robbiethe1stthe one I use for BM password lock10:13
robbiethe1stif it exists, load the root's /etc/passwd, otherwise use a stock one with a default password10:14

_PanzerSajtcan you explain it to me?10:14
*** VDVsx has joined #maemo10:14
keriorobbiethe1st: or just require a hashed password in it10:15

robbiethe1stBut I'm using the official login app or w/e10:17

ShapeshifterHi. So this morning my alarm didn't ring and I found my n900 in some sort of frozen state. The led is blinking as if I received an IM message and if I slide or double-tap power, the screen turns on but it remains black. I had this once before, and I'm sure replacing the battery fixes it. But I would like to know what is going on. So I'm able to ssh onto it, luckily, and I see that a process called sgx_misr is using up all CPU.12:24

*** maybeArgh has quit IRC14:09

freemangordonwrong link, but don;t ask me why14:14
freemangordonDocScrutinizer05: google for ldrex/strex14:15
freemangordonyeah, those are the instructions14:19
DocScrutinizer05not only instructions but also a general concept how to use them14:19
keriooh ARM <314:20
freemangordonyeah,but difference with my code is that I am not trying to aquire the lock, but to set a value14:20
freemangordonMUTEX_SET is called from the outside for() loop who checks the result14:20
DocScrutinizer05aiui MUTEX_SET is actually acquiring a lock14:21
freemangordonyes, but the check if the lock is aquired is not in MUTEX_SET14:21
freemangordonthe example on ARM site does that too, i.e it does a spinlock14:22
freemangordonnot a mutex14:22

freemangordonDocScrutinizer05: not so simple, as I have to return correct result to the upper for() loop14:24
DocScrutinizer05so your upper layer code gets result OK/FAIL from call to MUTEX_SET14:24

Palifreemangordon, first we need if disabling onenand fixed booting...15:23
fastaDocScrutinizer05: how do you manage your tweaks?15:23
DocScrutinizer05fasta: originally (like: in 1995+-) it was because suse been local for me. Now it's because openSuse is closely linked to SLES/SLED15:23
PaliI think that in -12 was still onenand code disabled15:23
DocScrutinizer05(manage tweaks) with lots of pain felt in the arse15:24
freemangordonPali: but attached kernel is kernel-cssu315:24

Palifreemangordon, ok15:24
DocScrutinizer05U usually avoid to do that15:25
freemangordonPali: so we need merlin199115:25
fastaDocScrutinizer05: so, you dd everything?15:25
Paliyes, somebody who has non working uboot15:25
fastaDocScrutinizer05: e.g. harddisk upgrades, etc.15:25
freemangordonyay, ubuntu still boots15:25
Paliping Sicelo15:25
fastaDocScrutinizer05: I wrote some scripts to write to /etc files, select the right alternative for various things, etc., according to my needs.15:26
fastaDocScrutinizer05: so, when I run that script, I have morphed a completely useless machine into something that does something useful.15:26
DocScrutinizer05IF I have to, it's: install openSuse_x, go thru all the packages manually in installer, opt-out/in a lot. then have two weeks minimum of days filled with tweaking all sorts of stuff, like global kbd shortcuts, themes, mail, $arbitrary-systems15:26
fastaDocScrutinizer05: yeah, I used to do that.15:27
fastaDocScrutinizer05: now every change I make is made programmatically.15:27
DocScrutinizer05on suse, there's autoyast, you'll like that if you get the catch of it15:27
fastaDocScrutinizer05: I still don't have a solution to manage Firefox extensions, though.15:27
fastaDocScrutinizer05: firefox had an API to install extensions.15:27
fastaBut they threw it out.15:27
fastaSo much for 'unleash the power of the web'.15:28
fastaThunderbird also is completely obnoxious because of their contracting with Microsoft.15:28
fastaEverytime you upgrade, they set some things by default.15:29
fastaAnyway, nothing which a little scripting cannot defeat, but imagine doing that by hand every single time.15:29
fastaOtherwise thunderbird is great.15:29
fastaNot a single crash in over a year or so.15:29
fastaDocScrutinizer05: autoyast sounds nice15:30
DocScrutinizer05a friend of mine has to maintain literally 10,000s of clients, and he's all full of joy about autoyast15:31
DocScrutinizer05(he's been a notorious yast-hater in former times ;-d)15:32
fastaDocScrutinizer05: but autoyast seems to be only for installation, not maintenance.15:32
DocScrutinizer05now he defends suse against almost everything else15:32
DocScrutinizer05yes, autoyast is a mere installation+deployment tool15:33
fastaDocScrutinizer05: Via NixOS you can do similar things, but do maintenance too.15:33
keriojust debootstrap the clients15:33
DocScrutinizer05for general local admin there's yast at large15:33
DocScrutinizer05for admin of 1000s of clients, there are shell tools15:34
fastaIt would be interesting to see how long it would take to install 2000 packages with the various tools.15:34
fastaI think Nix would come in first, assuming the packages existed!15:34
fastaApt would come in second.15:35
fastaAnd Fedora last.15:35
fastaSuse uses the same tools as Fedora, right?15:35
fastaI mean 'rpm'.15:35
*** Darkchaos2 has joined #maemo15:35

DocScrutinizer05jacekowski explained to me that in N900 xloader and NOLO are integrated into one chunk16:21
PaliDocScrutinizer05, if you boot nolo without valid kernel image and you have serial console, you will see that nolo has command line16:22
DocScrutinizer05ROMBL only checking signature of first part of that chunk that contains the xloader code, I guess16:22

Sicelowhere is it?19:08
freemangordonSicelo: kernel-cssu3 ;)19:09
freemangordonattached kernel that is19:09
freemangordonPali: do you know where in the kernel code is onenand init for rx5119:10
freemangordoni need base address and CSn19:10

Palior try arch/arm/mach-omap2/board-rx51-flash.c + board-n800-flash.c19:12
freemangordonalready tried19:12
Pali(yes rx51 calling n800 functions :D)19:12
freemangordonno, they are just declared19:12
Palimerlin1991, can you test freemangordon uboot build?19:12
Palifreemangordon, parsing omap parition table is implemented in some n8xx function19:14
Paliand that omap atag is same for n8xx and n90019:15
freemangordonyes, but i miss HW settings19:15
Palibtw, what is this code doing?: return &rx51_sdrc_params[0];19:15
merlin1991freemangordon: so you have kernel cssu3 attached ??19:18
merlin1991why does it say +zImage-2.6.28-omap1 then? :D19:18
freemangordonNFC, ask pali19:19
Palimerlin1991, because debian/rules has hardcoded that name19:19
merlin1991okay I'll reboot and flash19:20
freemangordonPali: r = gpmc_cs_request(c->gpmc_cs, ONENAND_IO_SIZE, &c->phys_base);19:21
merlin1991freemangordon, Pali: it boots19:22
Palinice :-)19:22
merlin1991so what did you guys change? :D19:22
freemangordondisabled onenand and mtdparts support19:23
merlin1991but -12 at least had no onenand support, no idea about mtdparts19:23
freemangordonmerlin1991: 2204 uses different onenand chip19:24
merlin1991yeah but to my understanding, in the -12 image I got from pali there was no onenand support?19:24
SiceloPali: freemangordon .. not booting. after i choose 'Attached Kernel' , device reboots in about 5 seconds19:26
Sicelowatchdogs maybe?19:26
merlin1991Sicelo: boot a not attached kernel19:26
merlin1991attached is the one from cssu-thumb19:26
merlin1991where you probably have no modules19:26
freemangordonSicelo: do you have cssu-thumb installed?19:26
freemangordonwell, then you don't have kernel-cssu3 as well :P19:27
freemangordonPali: and deffinitely base address is 0x0400000019:27
Paliare you going to add onenand support?19:28
freemangordonwill try at least19:28
SiceloPali: you still have a .deb of -11 around?19:30
Palino deb, but only image19:30
PaliDocScrutinizer05, freemangordon, is driver for n900 led too complicated or is easy to port it to uboot?19:34
DocScrutinizer05basically easy19:35
Palisometimes it is really bad when led is turned on19:35
DocScrutinizer05though a tad fsckdup (based on LP5521 properties)19:35
Paliand display backlight?19:35
merlin1991hehe now we need led and charge support in u-boot, then we can go FUCK act_dead we do proper battery recovery :D19:35
Palisometimes nolo turned display off...19:35
DocScrutinizer05but maybe you just want to talk to LP5523 via direct I2C rather than porting full driver for that19:35
PaliDocScrutinizer05, I think that uboot needs only to turn led off... nothing more19:36
* DocScrutinizer05 just muses about how things/own motivations become more clear in hindsight19:37
Palimerlin1991, I can write charge support19:37
Palibut first I want to shred -u BME19:37
merlin1991btw are you goign to upstream the n900 u-boot changes Pali?19:39
Palifreemangordon, are you sure that all closed maemo applications (except hald-addon-bme) using libbmeipc only for temperature?19:39
Palimerlin1991, yes, I want to upstream n900 uboot19:40
PaliI already sent more patches, but they was not merged19:40
Pali(due to some changes in uboot core for relocation)19:40
merlin1991hm is there a dedicated mailinglist for u-boot?19:41
DocScrutinizer05Pali: (using libbmeipc) maybe that's really hard to tell19:42
merlin1991ah found it19:42
merlin1991sometimes I hate google, I search for u-boot and it gives me a billion entries for the submarine thanks to my "german speaking" ip19:42
DocScrutinizer05Pali: I could figure some of those closed maemo apps will do some exceptional stuff in exceptional situations, like overheated device etc19:42
