| IntuitiveNipple | Any ACPI team available for a brain-storm/review on a suspend S3/immediate-resume issue I'm working on? | 06:30 |
| mrec | Hi guys, I have a driver which supports around 50 devices; The driver consists of a module which acts as a kernelspace<->userspace wrapper. The actual algorithms and firmware code is implemented in userspace | 06:31 |
| mrec | it's about a TV/DVB-T usb driver | 06:32 |
| mrec | it doesn't require any change at the existing kernel sources, it just adds code and the possibility of userspace drivers. | 06:32 |
| mrec | In userspace a daemon will load the requested drivers automatically | 06:33 |
| mrec | that daemon is started by udev so that the user doesn't have to bother about it | 06:33 |
| mrec | I wonder if there's a way to integrate that in ubuntu? | 06:33 |

| === OGDA is now known as BFTD | ||
| amitk_ | IntuitiveNipple: There is nothing in that report regarding the HW in use. https://wiki.ubuntu.com/KernelTeamBugPolicies should help us gather all the required info before we can start analysis | 10:59 |
| IntuitiveNipple | I just need to pick your brains for any reasons you can think of for an immediate resume after a successful suspend | 11:00 |
| IntuitiveNipple | I'm away of the policies... I recently joined ACPI team, I've got 2 identical units where one will resume correctly and the other will resume immediately. it appeared to be a PM_TIMER issue but it seems the ACPI_FURE_USAGE functions to read the wakeup event isn't quite correct, so it might be caused by something else | 11:02 |
| IntuitiveNipple | s/away/aware/ | 11:02 |
| IntuitiveNipple | Wondering if you've seem similar situations and if so, what the causes were | 11:02 |
| amitk_ | IntuitiveNipple: I haven't seen it before. But are you sure that the system even went into S3? Perhaps it aborted half-way through? | 11:03 |
| amitk_ | usb drivers are a problem many times | 11:04 |
| IntuitiveNipple | Yeah, positive. I've been building custom-debug kernels with ACPI_FUTURE_USAGE enabled and my own code in hwsleep() | 11:04 |
| IntuitiveNipple | what is strange here is - two identical Vaio notebooks, identical clean installs of Ubuntu on clean disks, even tried swapping the hard disks between them. Left battery out for 12 hours, etc, but one will always resume immediately. | 11:05 |
| IntuitiveNipple | I thought it was a PM_TIMER event until I tested it on the 2nd unit and found it worked... so now I'm looking for other reasons to investigate | 11:06 |
| IntuitiveNipple | I have debug code leading right up to the final CPU cache flush, and kicking in immediately it does "Back to C!" and not been able to find a thing different... I've run diffs of the kern.log of the two of them and they are identical, despite one having resumed immediately | 11:07 |
| amitk_ | IntuitiveNipple: Bios settings? | 11:08 |
| IntuitiveNipple | i've diffed the hardware setup, and the dmesg logs, and both units are identical | 11:08 |
| IntuitiveNipple | BIOS settings identical too, same BIOS versions, (not alot to set in the BIOS anyhow) | 11:08 |
| IntuitiveNipple | same hardware IDs and revisions | 11:08 |
| IntuitiveNipple | no problems with any of the drivers during suspend/resume and it can be repeated endlessly and won't get unstable | 11:08 |
| IntuitiveNipple | the actual suspend/resume is perfect - aside from this one that just doesn't want to stay in S3 :) | 11:09 |
| IntuitiveNipple | I thought checking which WAKE event flag was set on resume would give me the culprit, but both report the same thing: | 11:10 |
| IntuitiveNipple | Back to C! ( | 11:10 |
| IntuitiveNipple | Enabling PM Timer ( | 11:10 |
| IntuitiveNipple | Resume status=0 ( | 11:10 |
| IntuitiveNipple | Resume ACPI state=3 ( | 11:10 |
| IntuitiveNipple | Event 0=0x1 ( | 11:10 |
| IntuitiveNipple | Event 1=0x0 ( | 11:10 |
| IntuitiveNipple | Event 2=0x0 ( | 11:10 |
| IntuitiveNipple | Event 3=0x0 ( | 11:10 |
| IntuitiveNipple | agpgart-intel 0000:00:00.0: EARLY resume | 11:10 |
| IntuitiveNipple | (thats my debug code reporting) | 11:10 |
| IntuitiveNipple | Always says Event 0, which equates to PM_TIMER - no both - even when the PWRBTN is used... which is why I think there's still some work to do on the functions covered by ACPI_FUTURE_USAGE | 11:11 |
| IntuitiveNipple | s/no both/on both/ | 11:11 |
| IntuitiveNipple | but the upshot is I can't reliably trust the wake-event reporting in order to diagnose it! | 11:12 |
| amitk_ | This one perhaps? http://www.mail-archive.com/linux-acpi@vger.kernel.org/msg06777.html | 11:13 |
| IntuitiveNipple | Unfortunately not, I looked at Mattia's issue in the early stages when I thought it was a driver issue and knew that Firewire is an issue. | 11:15 |
| IntuitiveNipple | Mattia's issue was that it got 'stuck' during the suspend operations. In the case I'm dealing with the notebook suspends correctly | 11:16 |

| IntuitiveNipple | I did test disabling *all* wake events, and then it did correctly suspend... of course I couldn't wake it up, had to remove battery to reset, but it proved it is something to do with wake-up events | 11:19 |
