[Kern Meetup Blr] [CFP] : Talk Proposal - Low power modes for Heterogeneous System on chip (SoC) Architectures

[MANTENA PRASANTH BABU]

Preferred Format: 25+5 mins (open for Lighniting talk as well)

Abstract: 

Heterogeneous systems are increasing day by day due to their capability to integrate different variety of CPUs, GPUs and specialized accelerators. In such type of complex systems, power management becomes crucial and by implementing low poer techniques, the SOCs can significantly reduce the power consumption while maintianing performance capabilities.

This talk walks through the suspend and resume flow in the Linux and Uboot cycle and presents a solution to Multi-CPU Architecture SOCs where multiple CPUs can serve as a suspend masters when other CPUs running a different OSes otherthan Linux can be masters resume back safely protecting the critical firmwares like ATF and OPTEE and bringing them back to life, minimizing power consumption and heat dissipation, making it well-suited for gateway and automotive applications.

Brief Agenda

- Suspend flow in Linux

- Resume flow in Uboot.

- How multiple masters are handled between OSes

- Talk about Low power modes enablement on Texas Instruments TDA4 class of Jacinto devices

Speaker Bio:

 Prasanth Babu Mantena is Embedded Software Engineer at Texas Instruments with 5+ years of experience in Multimedia, OSPI, DMA and Linux power management.

Thanks,

Prasanth Babu Mantena
