01:48.39 | nh_home | proberts: could your memory address problem be related to that link I posted yesterday about kmem on arm processors? |
01:49.27 | nh_home | http://lists.arm.linux.org.uk/pipermail/linux-arm-kernel/2005-November/032390.html |
01:51.33 | nh_home | Check out the links listed in that post. |
01:56.51 | nh_home | florian: it's scary when I search for things totally unrelated to openezx and your name keeps coming up. :P |
02:30.32 | proberts | nh_home: Thanks for the link... I'll check it out when I get home. |
02:32.03 | proberts | nh_home: I was able to read and dump (I think) the entire pysical memory with mmap, but the kernel symbol table gives me invalid addresses... so I think I need to do some translation or something for ARM. |
02:33.21 | proberts | I could grab about 64MB starting at 0xa0000000, and then some memory lower in the 0x30000000 range, but the kernel syms are 0xc0000000 and 0xd0000000 |

11:14.05 | lkcl | hellooooo! my (broken) a120 arrived! mmm.... heeeelllp... |
11:14.53 | lkcl | s/a120/a780 |
11:20.19 | florian_kc | :-) |
11:20.23 | florian_kc | hi stefan_schmidt |
11:20.31 | florian_kc | lkcl: what is broken? |
11:20.43 | lkcl | ooo, don't know yet. |
11:21.05 | lkcl | the guy flashed it with new firmware (unspecified as to how) and now it "doesn't work (tm)" |
11:21.13 | lkcl | so, it's my turn to try and fix it. |
11:21.21 | florian_kc | i guess it was cheap, right? :-) |
11:21.22 | lkcl | i've found the bootloader instructions |
11:21.29 | lkcl | not very! |
11:21.46 | florian_kc | do you get the bootloader screen? |
11:22.05 | lkcl | he got a couple of extra batteries and an external charger to see if that was the problem |
11:22.06 | lkcl | no. |
11:22.22 | lkcl | it's camera, jog-wheel and power-on, right? |
11:23.42 | florian_kc | yes, you need to be be careful to press the center of the jog only |
11:24.00 | lkcl | ok |
11:24.09 | lkcl | nope - nothing. oops |
11:24.47 | lkcl | do you have to have a sim card in it? |
11:25.04 | lkcl | wouldn't have thought so, but... |
11:25.39 | florian_kc | that doesn't matter |
11:26.22 | lkcl | huh. ok. |

17:32.33 | stefan_schmidt | Yesterday was a bad day. Two broken server and one broken car. :( |
17:32.59 | stefan_schmidt | And even no working serial console from the testpads. |
17:33.34 | file | maybe today will be a good day then |
17:34.33 | prpplague | should feel lucky it wasn't two broken legs and a broke bank account, hehe |
17:34.57 | prpplague | file: to die? |
17:35.33 | file | prpplague: eep |
17:35.45 | prpplague | file: greetings, btw |

19:38.52 | proberts | OT: Anyone using a CA0106 -baed audio card in the linux box? (Audigy LS) |
20:09.11 | nh_home | proberts: nope, what's the problem though? |
20:11.13 | proberts | Sound output suddenly changed to all noise. Apparently if you boot to windows then soft-reset it works fine. No windows on this box. (found a lot of google hits for the same problem but no solution) |
20:11.48 | nh_home | proberts: doesn't work after a hard reboot? |
20:12.23 | proberts | no -win drivers must do something to the card... I think it might be stuck in digital I/O mode. |
20:12.39 | nh_home | ah |
20:13.20 | nh_home | yeah, no idea. The last non-integrated soundcard I had was an old sblive value. |
20:13.46 | nh_home | I've had to mess around with alsa a lot, but nothing like this. |
20:17.37 | nh_home | btw, I've been looking through your code, but I don't see anything obviously wrong. |
20:19.12 | proberts | If that method works it'll be an easy solution (until they policy out insmod) |
20:21.08 | nh_home | proberts: yeah. I've been wondering what their motivation is. Do they really want to keep us out, or are they trying to protect themselves from people who telnet into their phone and delete the bootloader or something... |
20:22.32 | proberts | There's a whole lot of restrictions placed on user ezx, which makes sense. That way a downloaded app launched from the GUI has a hard time doing anything malicious (or accidentally...) |
20:23.28 | proberts | One thing I noticed is I couldn't mknod in /dev, even though /dev is not listed in the policy file. I didn't see any hardcoded constants in the source. |
20:23.32 | nh_home | I'm just surprised they left so much open... kmem, insmod, read access to the policy file, etc etc... |
20:23.57 | proberts | yeah - for root at least. |
20:24.00 | nh_home | proberts: I'm rather worried that the src we have isn't exactly what's on the phone. |
20:24.44 | nh_home | they talk about "scrubbing" it before they release. If that just means removing config files that's one thing... |
20:50.53 | proberts | nh_home: There's clearly some tool they have for interfacing with the policy engine that must get removed. There's no reason to have those functions exported from the kernel module using user-space arguments otherwise. |
20:52.00 | nh_home | true |
20:53.55 | nh_home | So the question is why doesn't your program appear to disable it... |
21:19.42 | nh_home | proberts: have you tried calling any of these other functions/ |
21:19.44 | nh_home | ? |
21:37.54 | nh_home | proberts: hrm... I think I might have found the problem. ac_policy_enable is an extern int in acplug.h, but it is redefined locally as "1" in ac_policy.c |
21:48.28 | nh_home | wait, does that redefine it? I confess my C is pretty rusty. |
21:56.45 | nh_home | ok, nevermind. After a quick C lesson, I see that the header is declaring the variable, while it's being defined in ac_policy.c. :) |
21:58.57 | nh_home | You'll have to go easy on me, it's been a while. ;) |
