| 03:25.14 | LinuxMercedes | wait |
| 03:25.18 | tmzt | paste the output here, just short though |
| 03:25.26 | tmzt | like the last line |
| 03:26.12 | LinuxMercedes | No rule to make drivers/video/syscopyarea |
| 03:27.01 | LinuxMercedes | I hate to ask in here but I can't massage the information out of google =/ |
| 03:28.17 | tmzt | here is fine |
| 03:28.21 | tmzt | it's what we do |
| 03:28.28 | LinuxMercedes | thanks! |
| 03:28.34 | LinuxMercedes | wait what |
| 03:28.50 | tmzt | what we don't like so much is trying to figure out what build or whatever you have, then there's -chat for that |
| 03:28.50 | LinuxMercedes | well, apparently M=drivers/video decided to make all the modules. |
| 03:29.01 | LinuxMercedes | ah okay. |
| 03:29.03 | tmzt | you don't use M= in the kernel tree |
| 03:29.08 | tmzt | I thought you were building standalone |
| 03:29.15 | tmzt | just make modules |
| 03:29.17 | tmzt | make modules_install |
| 03:29.29 | LinuxMercedes | well, I'm cross-compiling for my phone. |
| 03:29.31 | tmzt | I use INSTALL_MOD_PATH in front of that to keep the arm modules separate |
| 03:29.47 | LinuxMercedes | that's a good idea. |
| 03:29.51 | tmzt | yes, so you add CROSS_COMPILE=/path/to/prefix- and ARCH=arm |
| 03:29.56 | LinuxMercedes | let me see if this driver works nicely |
| 03:30.00 | LinuxMercedes | yep that's what I do |
| 03:30.33 | LinuxMercedes | Trying to get a displaylink screen working. |
| 03:30.49 | LinuxMercedes | With the hopeful intent of getting a laptop-ish setup for my phone. |
| 03:31.08 | tmzt | what's syscopyarea? |
| 03:31.16 | tmzt | is it used for displaylink? |
| 03:31.17 | LinuxMercedes | It's part of the framebuffer libraries |
| 03:31.21 | LinuxMercedes | so yeah |
| 03:31.28 | tmzt | it's not msm specific |
| 03:31.29 | tmzt | ? |
| 03:31.39 | LinuxMercedes | what's msm again? |
| 03:31.45 | LinuxMercedes | (I don't think it is) |
| 03:31.56 | tmzt | qualcomm |
| 03:31.58 | tmzt | what device is it |
| 03:32.02 | tmzt | oh |
| 03:32.04 | tmzt | nexus s? |
| 03:32.16 | LinuxMercedes | nexus one |
| 03:32.20 | tmzt | it is |
| 03:32.25 | LinuxMercedes | well dang. |
| 03:32.29 | tmzt | it's qsd8k/snapdragon |
| 03:32.33 | LinuxMercedes | yeah |
| 03:32.50 | tmzt | you would probably find the kernel source in arch/arm/mach-msm |
| 03:33.10 | LinuxMercedes | okay |
| 03:33.19 | LinuxMercedes | odd, because other drivers pulled from drivers/ work fine |
| 03:33.25 | tmzt | sure |
| 03:33.40 | tmzt | most drivers in linux are cross platform |
| 03:33.51 | LinuxMercedes | oh, that makes sense. |
| 03:34.20 | LinuxMercedes | let me see if it's in the arm branch too. |
| 03:35.13 | LinuxMercedes | I don't see it. |
| 03:36.00 | tmzt | you're right it's shared |
| 03:36.12 | LinuxMercedes | yay |
| 03:36.14 | tmzt | wow arm asm would be faster |
| 03:36.24 | tmzt | maybe |
| 03:36.30 | LinuxMercedes | well, maybe I'll throw that on the list of things to look into |
| 03:37.48 | tmzt | but I don't understand how this is related to displaylink |
| 03:38.36 | LinuxMercedes | The udlfb module, which is the driver for displaylink stuff, needs these modules. |
| 03:38.56 | tmzt | okay |
| 03:39.10 | tmzt | it would be better to have dl in the android bitflinger probably |
| 03:39.23 | tmzt | like the X driver that exists for it |
| 03:39.24 | LinuxMercedes | in the which? |
| 03:39.28 | LinuxMercedes | oh, yeah |
| 03:39.31 | LinuxMercedes | that'd be better |
| 03:39.31 | tmzt | to track regions updates |
| 03:39.42 | LinuxMercedes | but this stuff is horribly experimental and ad-hoc =/ |
| 03:40.04 | tmzt | yeah |
| 03:40.18 | LinuxMercedes | I'd like to eventually get it more stable and a lot less painful to use |
| 03:40.19 | tmzt | it's similar to how the msm's display works, or at least did before nexus one |
| 03:40.39 | LinuxMercedes | I haven't looked into how the G1 worked |
| 03:40.44 | tmzt | I don't belive it's using mddi for the main display like the 7k's did |
| 03:42.03 | LinuxMercedes | I'm not sure, to be honest |
| 03:42.47 | LinuxMercedes | dangit, exec format error when I try to insert the modules. |
| 03:43.12 | LinuxMercedes | probably need a make clean before I make. |
| 03:48.23 | tmzt | that's probably a version issue |
| 03:48.26 | tmzt | not easy to fix |
| 03:48.40 | tmzt | you need to run make oldconfig; make prepare |
| 03:48.50 | tmzt | you also need to have the same version |
| 03:49.03 | LinuxMercedes | yeah |
| 03:49.08 | tmzt | you can look at github.com/tmzt/g2root for some scripts that might help |
| 03:49.18 | LinuxMercedes | I had messed around some with some kernel stuff before I got this, though |
| 03:49.23 | LinuxMercedes | so I'm guessing it might just be that. |
| 03:49.44 | tmzt | copy .config out and make mrproper |
| 03:49.59 | LinuxMercedes | I'll take a look at those scripts |
| 03:53.28 | LinuxMercedes | which g2root repository is it? You have about 4. |
| 03:54.23 | tmzt | hmm, probably master |
| 03:54.27 | tmzt | i'ts been a while |
| 03:54.36 | tmzt | it's under my stuff (tmzt) |
| 03:54.41 | LinuxMercedes | okay |
| 03:54.44 | tmzt | because we shared a repo and I was just managing the git |
| 03:54.55 | LinuxMercedes | well, your link 404'ed, but you have about 4 related repositories. |
| 03:55.20 | tmzt | oh |
| 03:55.24 | tmzt | remind me |
| 03:55.30 | tmzt | tools for rooting |
| 03:55.33 | tmzt | or modules |
| 03:55.36 | tmzt | it one of those |

| 14:23.22 | emwe | yap, me neither. but i saw that in dmesg. |
| 14:23.49 | emwe | what's up on your side? |
| 14:23.51 | [acl] | it could be a matter of delay. The h2w is really sensitive to those delays it has |
| 14:24.05 | [acl] | emwe: ill prob bring in light sensor for the rhod.. thats all for now. |
| 14:24.27 | emwe | ah, might explain it. i get some huge hickups (accompanied with high cpu usage for very long periods) |

| 14:25.02 | [acl] | emwe: need to implement the correct workers for the 3.5mm recognition. |

| 14:26.05 | [acl] | in winmo it calls that detect function thats on the h2w driver. that part is scary how similar the codes are :-\ |
| 14:26.43 | emwe | isn#t that what "insert_headset" is for? that's not the detector, right? |
| 14:26.50 | emwe | ( i already forgot everything about it) |
| 14:27.27 | [acl] | there is another fucn that is called i believe to make sure its one of the supperted h2w devices |
| 14:27.32 | [acl] | if it passes the test, then goes to insert headset |

| 14:29.33 | [acl] | hmm i dunno let me find the code |
| 14:29.50 | emwe | that's what calls insert_headset() then |
| 14:30.28 | [acl] | yeah thats it |

| 18:07.43 | marxx | hi, anyone with knowledge on msm7201a/msm7200 arm9's memory protection/mapping mechanism? would like to hear some info on it. :) (hope is not too off-topic for "htc-linux") |
| 18:09.23 | arrrghhh | i'd say it's right on topic. dunno if you'll get an answer anytime soon tho :P |
| 18:10.53 | phh | marxx: memory protection? |
| 18:10.54 | phh | which one ? :D |
| 18:11.16 | arrrghhh | unless phh is around ofc :P |
| 18:11.29 | phh | the only thing i know is how to disactivate it |
| 18:11.54 | marxx | nice :) |
| 18:12.24 | phh | marxx: smi or ebi ? |
| 18:12.36 | marxx | peripherals, actually |
| 18:12.41 | phh | errr |
| 18:12.48 | phh | that will be guess & try |
| 18:13.09 | marxx | you see: there is a lot of peripherals I can talk to when on arm9 |
| 18:13.16 | marxx | but from arm11, i cant see them |
| 18:13.29 | phh | which one do you mean ? |
| 18:14.22 | marxx | any peripheral can't be seem from arm11. if I try to peek any, the cpu faults with data abort |
| 18:14.32 | marxx | well, let me explain something first: |
| 18:14.49 | phh | (while you explain i'm searching) |
| 18:15.26 | marxx | i'm researching a device based on msm7201a, it runs BREW. i'm trying to get this thing to run linux instead |
| 18:15.53 | marxx | so, since there is msm7201a support on linux kernel, it wouldn't be THAT hard :) |
| 18:16.16 | marxx | but, as I said, from arm11 side, every periperhal is blocked, or something like that |
| 18:16.27 | marxx | i cant use UART to output debug info :( |
| 18:16.27 | phh | *(0xA82Y0800)=0; |
| 18:16.34 | phh | where Y is some value you'll have to find. |
| 18:16.47 | phh | or EBI Y=0, for SMI Y=5 |
| 18:16.52 | phh | for* |
| 18:16.54 | marxx | hmm |
| 18:17.06 | phh | perhaps AXI isn't available for you though |
| 18:17.13 | phh | that would make sense |
| 18:17.22 | marxx | when reversing the OEMSBL, i found two instances of that address: 0xa8240000 and 0xa8250000 |
| 18:17.30 | marxx | but they are not documented :O |
| 18:17.50 | marxx | i tried that |
| 18:17.59 | phh | there is a +0x800 |
| 18:18.40 | marxx | yep, zeroed 0xa8240800, 0xa8250800, 0xa0b00000 (nand mpu), 0xa0e00400 (peripheral mpu) |
| 18:18.54 | marxx | none actually works, still blocked :( |
| 18:19.11 | marxx | dunno if that matters, but, for example |
| 18:19.50 | marxx | if i try to read any peripheral with JTAG, the data that comes out, is always the lastest that has been succesfully read |
| 18:20.06 | phh | you've got jtag ? wow ... |
| 18:20.11 | marxx | yep |
| 18:21.07 | marxx | for example, if i read addr. 0, it returns the first indirect jump from the vector table, says 0xeafffffe (its a branch to itself, just for example lol) |
| 18:21.46 | marxx | then, if i try to read from a peripheral, it returns the same 0xeafffffe, for every address inside that peripheral addr. range |
| 18:22.19 | marxx | i even tried to inject dream OEMSBL mpu setup code on it, no good |
| 18:22.36 | phh | i'm afraid noone can help here :/ |
| 18:22.39 | phh | we don't have such things |
| 18:22.59 | marxx | :( |
| 18:23.17 | marxx | well, thats ok, i'll spend some more time on it |
| 18:23.23 | marxx | its just very strange |
| 18:24.50 | marxx | not even 0xc0000000, which is supposed to be arm11's private peripherals is accessible. how does BREW actually runs on this thing, without being able to access anything |
| 18:25.38 | marxx | does QCSBL messes with mpu or something like that? |
| 18:33.46 | marxx | any idea where to look? it seems I'm s.o.l. :/ |

| 18:51.59 | Alex[sp3dev] | so what's up with 39 microp? are you rhod/diam guys moving to microp-ng? The problem with current code except that it's unreadable is that it does not set leds in a workqueue and i2c sleeps so if you set a led trigger, it hangs.. anyway i'm planning on moving kovs to 39 and moving my 'rewritten' amss stuff for 35 to 39 so we can integrate acoustic to xdandroid.. but i'm lazy now |
| 18:53.06 | marxx | hmm, i'll check that out. thought that would just apply when using mmu. my mmu is disabled, so i'm accessing everything on a flat addressing scheme/physical |

| 21:20.34 | stinebd | [acl]: the wifi rename is mainly in consideration of future development... for nand, we don't want to have to muck around with init.rc during boot and that will prevent having to do so in the future, while keeping our divergent code as unintrusive as possible. if you don't like it, fork it :P |
| 21:21.15 | stinebd | similarly we now have an abstract hci_attach service for bluetooth |
| 21:21.50 | [acl] | stinebd: nahh its fine.. the libs are part of xdandroid and since everything is userland, it fine the way it is. It would be a pain if i used the same libs for another build. but each build will most likely carry their own libs |
| 21:22.42 | stinebd | we have a lot of ugly consequences of supporting 18 jillion different devices |
| 21:23.50 | WyrM | abstract hci_attach? what is that? |
| 21:24.09 | [acl] | stinebd: :-p .. all good. |
| 21:24.26 | stinebd | [acl]: i don't like to see my friends upset about code! |
| 21:27.21 | [acl] | stinebd: :-p .. i got used to it. i used to piss of phh all the time |
| 21:28.36 | [acl] | stinebd: any luck with the tpcal script from nand ? |
| 21:28.50 | [acl] | i mean reading the tpcal points from nand |
| 21:28.56 | stinebd | [acl]: we'll be doing that in rootfs soon |
| 21:29.09 | [acl] | merci |
| 21:30.18 | [acl] | thanks to hyc, myself and jb for putting that together. Jb went above and beyond and reversed the whole crc function too, but that would only be useful if we want to write points. but no need.. i wouldnt even want that on real nand. |
