Re: Feedback on hardware support for Odroid U3
Thanks! The patch for fan support is obviously on a good way to be applied. However, I just took now 4.2.3 from linux-stable and ran into the same problem of this conversation: https://lkml.org/lkml/2015/2/17/434 Is there a way I can help getting this debugged? I could apply this patch and test it if you like. Just asking because someone is maybe working on a better fix :) Here a more detailed output of this problem: http://pastebin.com/ity4cEAS Regards 2015-08-06 1:31 GMT+02:00 Krzysztof Kozłowski: > 2015-08-05 22:07 GMT+09:00 Thomas Pietrowski : >> Sorry for the long delay.

Sorry for the long delay. Got now linux-stable 4.2.0-rc5 running here, but I still miss the fan support. Searched the web again for the patch and found this on LKML: https://lkml.org/lkml/2014/12/18/138 Then looked at the arm-soc repository but found this patch nowhere.

CPU throttling and CPU cooling should be two seperate processes, isn't it? The stock Odroid U3 has only passive cooler. That's true, but they (hardkernel) also sell a optional fan and the socket for is is still there when buying the board. See, http://www.hardkernel.com/main/products/prdt_info.php?g_code=G138760358261 for the optional fan. Therefore, it is not a hardware hack or whatever. Probably support for fan could be added...

What happens when we simply disconnect the fan and the CPU hits higher temperatures? Will it still work on high frequencies or will it self-protect by using lower CPU frequencies? I do not know how the thermal/cooler driver works. I suppose it depends whether cooling device (the pwm-fan) reports non-working fan. You should rather ask on linux...@vger.kernel.org mailing list. That is the place for thermal framework. CPU throttling and CPU cooling should be two seperate processes, isn't it? Although cpu frequency driver is a separate thing but for cooling it behaves like a cooling device. A fan can be a cooling device. CPU frequency as well. The stock Odroid U3 has only passive cooler.
