Thermal microconference proposal @ LPC

Thermal microconference proposal @ LPC

[Amit Kucheria]

Hi all,

We've proposed a thermal microconf at LPC again this year. 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

Thermal/Power mitigation on high powered laptops

Some of the high powered laptops released with KabyLake and later
generations of processors can reach more than 50W with some busy
workloads like kernel compilation. 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,
Srinivas

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.

One slide to show power/thermal graph.
