I've bcc'ed a few people who were interested last year. We already have the following topics listed for the proposal but could certainly use more topics especially from the non-mobile Linux community. - Samsung: Thermal aware scheduling (Lukasz Luba) - Linaro: Combining idle and freq change for cpu cooling (Daniel Lezcano) - ARM: Discriminating thermal throttling (Volker Eckert) - IBM: Sustain turbo mode (Parth Shah) - QCOM/Linaro: Make thermal framework easier to use in products (Amit Kucheria) Please help bring this to the attention of those who might be interested in talking about thermal-related problems at the conference. Thanks. Regards, Amit Kucheria & Daniel Lezcano ^ permalink raw reply [flat|nested] 4+ messages in thread

This results in CPU temperature to quickly reach close to the critical temperature. To avoid this OEM’s have used a very conservative power limits by default. But this results in a bad performance on Linux laptops compared to other operating systems. We have implemented a solution for Linux to mitigate this. This quick presentation will show the approach Linux users particularly kernel developers can use to get a very high performance from these laptops. This should be a quick 5-10 min talk.

Thanks for the submission. Is this supposed to be a discussion or only a presentation? In any case, Rafael and Eduardo are now triaging the list of talks as MC leads.
