Accelerometer non functional (acer-wmi) in Acer W500/501

Bug #1055433 reported by Sean DS on 2012-09-24

This bug affects 1 person

Bug Description

The accelerometer is not detected as an acpi event. There is a patch (attached) which when applied to the acer-wmi.c source, allows the accelerometer to work.

It would be nice if the patch could be added upstream so us early ubuntu tab adopters can rotate at our leisure!

I found the patch in this link: http://www.linuxforums.org/forum/hardware-peripherals/189360-accelerometer-help-needed-arch-linux-kernel-3-4-a.html

I did not make the patch myself.

Can you provide some information on the status of the patch with regards to getting it merged upstream? Has it been sent upstream, what sort of feedback has it received, is it getting applied to a subsystem maintainer's tree, etc?

People affected by this bug are probably wondering why the kernel team doesn't just apply the patch and fix it. The reason is that the kernel team is reluctant (not opposed) to apply any patch to a stable kernel that is not from upstream. Applying patches that don't come from upstream add greatly to the support of the kernel as other upstream patches may touch the same area as the non-upstream patch and may prevent them from applying cleanly.

To submit your patch, send your patch with the detailed description/changelog and your Signoff (ending with Signed-off-by: your name <email>), to the emails listed from ./scripts/get_maintainer.pl drivers/SUBSYSTEM-DETAILS (the get_maintainer.pl is from the kernel sources). Once you have sent the patch upstream and it's accepted, please drop a note here so that we can cherry-pick/include the patch into Ubuntu kernel.

All I know is the information from:

and
blog.gmane.org/gmane.linux.drivers.platform.x86.devel/3350

The patch originated from a kernel developer but as of 3.5.rc6 it still has not been committed. I'll see what its status upstream is and drop a not here when I hear back.

The patch has made its way into the linux 3.6rc7 kernel and therefore has been merged upstream.

Thanks, I learnt a lot about kernel development today.
