[intrepid] isight_firmware module doesn't load isight.fw

[Steffen Röcker]

Binary package hint: linux-image-2.6.26-4-generic

The new isight_firmware module doesn't load isight.fw
I extracted the firmware (isight.fw) using isight-firmware-tools and copied it to /lib/firmware.
Don't know why it doesn't load it. This should not be a duplicate of bug #185634 as the 2.6.26 kernel has a new isight_firmware module. Hope this gets finally fixed for intrepid release.

dmesg:
[ 13.424348] firmware: requesting isight.fw
[ 13.903466] usbcore: registered new interface driver isight_firmware

lsusb:
Bus 005 Device 003: ID 05ac:8300 Apple, Inc. Built-in iSight (no firmware loaded)

This might just be a result of a typo on your part or ignorance on mine but isn't isight.fw supposed to go in /lib/firmware/ rather than /usr/lib/firmware/ ?

[Steffen Röcker (sroecker)]

Oh, thank you. I copied it to /lib/firmware, it was just a typo when I wrote the bug report.

[Steffen Röcker (sroecker)]

To debug I compiled udev with DEBUG=true and did udevadm control log_priority="debug" before modprobe isight_firmware.

The Ubuntu Kernel Team is planning to move to the 2.6.27 kernel for the upcoming Intrepid Ibex 8.10 release. As a result, the kernel team would appreciate it if you could please test this newer 2.6.27 Ubuntu kernel. There are one of two ways you should be able to test:

1) If you are comfortable installing packages on your own, the linux-image-2.6.27-* package is currently available for you to install and test.

--or--

2) The upcoming Alpha5 for Intrepid Ibex 8.10 will contain this newer 2.6.27 Ubuntu kernel. Alpha5 is set to be released Thursday Sept 4. Please watch http://www.ubuntu.com/testing for Alpha5 to be announced. You should then be able to test via a LiveCD.

Please let us know immediately if this newer 2.6.27 kernel resolves the bug reported here or if the issue remains. More importantly, please open a new bug report for each new bug/regression introduced by the 2.6.27 kernel and tag the bug report with 'linux-2.6.27'. Also, please specifically note if the issue does or does not appear in the 2.6.26 kernel. Thanks again, we really appreicate your help and feedback.

[Steffen Röcker (sroecker)]

Still doesn't work with 2.6.27.
There is also no entry in /sys/class/firmware/, maybe request_firmware doesn't get the right device.

$ uname -a
Linux helios 2.6.27-1-generic #1 SMP Sat Aug 23 23:20:09 UTC 2008 i686 GNU/Linux

[Andreas (andreas-kotowicz)]

doesn't work with kernel "Linux 2.6.27-2-generic #1 SMP Thu Aug 28 17:20:02 UTC 2008 i686 GNU/Linux" either :(

Is there any way we can try to debug this?

[Ricky Campbell (cyberdork33)]

are we supposed to be using isight-firmware-tools still? From what I can tell, the Ubuntu version of OFT does not have the ift-load binary anymore so we cannot even attempt to load the firmware manually... Is this supposed to be loaded in kernelspace again?

[Andreas (andreas-kotowicz)]

removing isight-firmware-tools and booting intrepid with the 2.6.27-2 allows me to use the camera again.

[Nathan (nathansamson)]

Removing i-f-t and rebooting doesn't resolve the problem for me.

But I read in this report about isight.fw that should be copied to /lib/firmware, should I do that, and if so, where do I get isight.fw?

Thanks

To extract the firmware from your OSX install mount your OSX
partition, most likely this command will do it:

sudo mkdir /MacOSX && sudo mount /dev/sda2 /MacOSX

Then install isight-firmware-tools and allow it to extract the firmware

It seems that simply copying the isight.fw file to /lib/firmware and then rebooting is the solution. firmware loading was moved into the kernel module again then I guess...

A related bug:

https://bugs.launchpad.net/ubuntu/+source/linux/+bug/289546

Or maybe a duplicate?

It also seems that removing isight-firmware-tools removes isight.fw from /lib/firmware. So isight.fw should be extracted to a safe location where it won't vanish when isight-firmware-tools is removed. Then it can be copied to /lib/firmware before the required reboot. As a side note, mine is working now :)

Thanks that is helpful info!

Per a decision made by the Ubuntu Kernel Team, bugs will longer be assigned to the ubuntu-kernel-team in Launchpad as part of the bug triage process. The ubuntu-kernel-team is being unassigned from this bug report. Refer to https://wiki.ubuntu.com/KernelTeamBugPolicies for more information. Thanks.

Firmware is available in the isight-firmware-tools package.

[Ricky Campbell (cyberdork33)]

Just a comment... the firmware is not available in the isight-firmware-tools package, it is extracted from a driver that is located on your OS X partition. I do believe this bug is not valid anymore however.
