Hi,

I have just installed Debian Stable on a new QNAP TS-212p (using the instructions at http://www.cyrius.com/debian/kirkwood/qnap/ts-219/install/), followed by kernel 3.16.0-0.bpo.4-kirkwood from wheezy-backports. I have three questions.

1. kirkwood-thermal (http://lxr.free-electrons.com/source/arch/arm/boot/dts/kirkwood-6282.dtsi?v=3.16 & http://lxr.free-electrons.com/source/drivers/thermal/kirkwood_thermal.c?v=3.16)

My TS-212p features MV88F6282 CPU (dmesg: Kirkwood: MV88F6282-Rev-A1, TCLK=200000000), for which a thermal driver 'kirkwood-thermal' is available. However, if I modprobe kirkwood-thermal, I get nothing in /sys/class/thermal. I assume this is a problem with the device tree? Should I file a bug for that?

2. cpuidle (http://lxr.free-electrons.com/source/drivers/cpuidle/cpuidle-kirkwood.c?v=3.16)

"# CONFIG_ARM_KIRKWOOD_CPUIDLE is not set" in the 3.16.0-0.bpo.4-kirkwood config. Is this intentional?

3. cpufreq-kirkwood (http://lxr.free-electrons.com/source/drivers/cpufreq/kirkwood-cpufreq.c?v=3.16)

"CONFIG_ARM_KIRKWOOD_CPUFREQ=y" is in the 3.16.0-0.bpo.4-kirkwood config but cpufreq-info reports that there is no driver active:

# cpufreq-info
cpufrequtils 008: cpufreq-info (C) Dominik Brodowski 2004-2009
Report errors and bugs to cpu...@vger.kernel.org, please.
analyzing CPU 0:
no or unknown cpufreq driver is active on this CPU

dmesg | grep cpufreq yields nothing. Is it a bug?

Thanks for your help.

Ian, are you familiar with these features?

Not really.

For #2 a bug report against the kernel would be appreciated so we can
consider enabling it for Stretch if not Jessie. Only problem would be if
it were something which has to be built in and it blew out the size of
the image too much. The decision to enable would be a lot easier if the
bug report contained a positive test result from having rebuilt with
that option, but that's not mandatory.

For #1 and #3 I think are questions for the upstream developers.

I'd suggest testing the 4.0.x kernel from Sid first though.

Ian.

Thanks for the reply. I am currently waiting for a USB-TTL converter and once I receive it, I will begin testing the 4.0 kernel.

Best regards,
