| fairuz | What does SW acknowledge means? | 12:30 |
| fairuz | (to clear an interrupt) | 12:30 |
| ohsix | its a bit the software handling the irq can set to tell the hw that it knows about the last one | 12:31 |
| === TheMuso` is now known as TheMuso | ||
| ohsix | usually to let the hw know its ok to discard something or move on | 12:31 |
| fairuz | ohsix: so normally writing 1 to the acknowledge register will do the job right? | 12:43 |
| ohsix | i dunno your circumstances, if that's what does it then yes | 12:45 |
| fairuz | Actually I cleared the interrupt but it stills reenter the handler | 12:52 |
| fairuz | so obviously there is something else that i'm not clearing :D | 12:53 |

| mahmoh | does anyone know how to override the bios for kvm support with a kernel option? kvm=enable? | 16:13 |
| tgardner | mahmoh, you generally have to enable virtualization in the BIOS | 16:14 |
| mahmoh | tgardner: I did but it's still reporting it's disabled in the bios, and I updated to the latest bios with the same results | 16:17 |
| mahmoh | ah, I might have to disable trusted execution on my dell hardware it appears ... | 16:19 |
| mjg59 | mahmoh: If it's reporting that it's disabled by the BIOS then the BIOS has (a) not enabled support and (b) has locked the MSR | 16:19 |
| mjg59 | And yes, if trusted execution is enabled and you want to use kvm then you may need to boot in a trusted setup | 16:20 |
| Krunch | you may also try to poke at the MSR manually http://timetobleed.com/enabling-bios-options-on-a-live-server-with-no-rebooting/ | 16:21 |
| mahmoh | there we go ... how much more confusing can they make it? | 16:22 |
| mahmoh | mjg59: I'm guessing there's no kernel override then ;) disabling the trusted execution worked (whew), so no problems anymore | 16:23 |
| mahmoh | except with Dell' | 16:24 |
| mahmoh | s bios that is | 16:24 |
| mahmoh | mjg59: thx | 16:24 |

| manjo` | jjohansen, and .. | 18:25 |
| jjohansen | manjo`: I'm not sure where you want to go with the bug from hear, | 18:25 |
| manjo` | so that means you are not seeing the bug ? | 18:25 |
| jjohansen | manjo`: basically the rtl driver needs to be removed during the install | 18:25 |
| jjohansen | manjo`: no I saw it plenty | 18:25 |
| jjohansen | manjo`: I updated Bug #744419 | 18:26 |
| ubot2 | Launchpad bug 744419 in linux "[NATTY] [ Kernel oops installing natty @tty_write()" [Undecided,New] https://launchpad.net/bugs/744419 | 18:26 |
| === herton_lunch is now known as herton | ||
| manjo` | hmm... not sure how we can fix that for natty... probably have udev rules that removes it ? | 18:26 |
| manjo` | udev rules based on DMI info ? | 18:27 |
| tgardner-afk | manjo`, blacklist in /etc/modprobe.d ? | 18:27 |
| === tgardner-afk is now known as tgardner | ||
| manjo` | tgardner-afk, right or that ... | 18:27 |
| jjohansen | manjo`: could black list it for the install disk, I'm not sure you want to black list for after, it seems to be working (for some value of working) | 18:27 |
| * manjo` writing to mmany udev rules these days | 18:28 | |
| manjo` | jjohansen, also can you install cheese and see if you can record video... the camera is not recording video and showing a blank screen on that one | 18:28 |
| manjo` | jjohansen, what would the rtl driver cause this bug ? | 18:29 |
| jjohansen | manjo`: hrmm give me a sec, I have cheese installed in both 32 and 64 bit but I never tried grabbing video | 18:29 |
| jjohansen | manjo`: I haven't chased it far enough to figure that out | 18:29 |
| jjohansen | manjo`: it took me a lot just to get the stupid thing installed, that was my limit for the weekend | 18:30 |
| manjo` | jjohansen, yeah natty is very busted on that x120e | 18:31 |
| manjo` | jjohansen, also if you switch your bios to legacy only and don't look for UEFI you will have better results | 18:31 |
| jjohansen | manjo`: hrmm, I don't know about that, I haven't found it any worse than natty on any of my other machines, all of which have problems | 18:31 |
| jjohansen | manjo`: also I just did a bios update on it this morning so we will see if that helps anything | 18:32 |
| jjohansen | manjo`: yep cheese crashes trying to record video | 18:36 |
| manjo` | jjohansen, it does the same on maverick too.. thanks for the confirmation | 18:36 |
| manjo` | jjohansen, this is with the latest bios update as well right ? | 18:36 |
| jjohansen | manjo`: yep | 18:38 |
| jjohansen | manjo`: so cheese gets stuck in a polling loop on fd 3 | 18:43 |
| jjohansen | manjo`: which is returning EAGAIN | 18:43 |
| manjo` | you think its a cheese bug ? | 18:44 |
| jjohansen | manjo`: well there is definitely a cheese bug there, it shouldn't let a device returning EGAIN send it into an infinite polling loop but the device isn't responding to the request | 18:45 |
| jjohansen | so at least 2 bugs | 18:45 |

| kamal | mjg59: got a moment to discuss intel_backlight in 2.6.39? | 20:38 |
| mjg59 | kamal: Sure | 20:40 |
| kamal | hi Matthew ... | 20:40 |
| kamal | it looks like most of your backlight work has landed in 2.6.39... I do see "backlight: add backlight type" and the nv_backlight and radeon_backlight bits, but the intel_backlight patch itself ("i915: Add native backlight control") appears to be missing. | 20:40 |
| kamal | do we know why that's the case? | 20:40 |
| mjg59 | We do not | 20:42 |
| mjg59 | I suspect it conflicted and Andrew dropped it | 20:42 |
| mjg59 | Let me try that again, then | 20:42 |
| kamal | ah | 20:42 |
| kamal | ok, I'll keep an eye on the repo (and intel-gfx?) for your retry... and will try cramming your previous version in myself to test in the meantime. | 20:43 |

| sforshee | mjg59, if you've got a minute, I was wondering about the fate of this patch: https://lkml.org/lkml/2011/1/19/331 | 20:58 |
| sforshee | the conversation seemed to die without a resolution | 20:59 |
| mjg59 | sforshee: I think I need to rewrite it from scratch | 20:59 |
| mjg59 | sforshee: I'm also worried about it breaking other systems | 20:59 |
| mjg59 | sforshee: But it's on my list - I was thinking about it today | 20:59 |
| mjg59 | It needs some infrastructural changes from ACPI to get the EC handle | 20:59 |
| sforshee | mjg59, yeah, the driver does seem pretty ugly | 21:00 |
| sforshee | that patch does get some systems working though | 21:00 |
| mjg59 | I was going to just rewrite toshiba_acpi completely at some stage | 21:00 |
| mjg59 | I guess I should do that on the plane tomorrow | 21:00 |
| sforshee | mjg59, looking forward to seeing the results :-) | 21:01 |

| mjg59 | manjo`: Does your X120e have the rtl wifi? | 22:41 |
| mjg59 | manjo`: If so, are you seeing stalls when it tries to request_firmware() on resume? | 22:42 |
| manjo` | mjg59, looking ... | 22:43 |
| manjo` | mjg59, yes it has rtl8192ce ... and I don't see stalls | 22:45 |
| mjg59 | manjo`: Ok. Using rtlwifi, or using the realtek driver? | 22:46 |
| manjo` | it resumes ok (I am on 10.10) 2.6.35-28 | 22:46 |
| mjg59 | Ah, the realtek one. Ok. | 22:46 |
| mjg59 | So rtlwifi is just buggy. I'll work on that. | 22:46 |
| manjo` | yep I am not on rtlwifi | 22:46 |
| manjo` | I am using the realtek driver | 22:46 |
| jjohansen | mjg59: yes the rtlwifi driver is very buggy, and yes I see stalls coming out of suspend sometimes, have also had coming out of suspend lock up | 22:48 |
| mjg59 | jjohansen: Yeah, I've just added it to the pm-utils unload/load blacklist for now | 22:50 |
| jjohansen | mjg59: the rtl8192ce driver is also responsible for the 64 bit install failures | 22:51 |
