Tuning Real-Time Linux for ARM SoCs - Bryan Brattlof, Texas Instruments
Embedded SoCs pose a challenge for Real-Time kernel work loads. Oftentimes, in heterogeneous architectures, the limited I/O, DDR, and CPU bandwidth is shared between TrustZone applications, GPU stacks, and all manner of ‘firmware’ running on the system at the same time with any one of them potentially degrading performance to unacceptable levels. So how can we tune a system where Linux must share resources with everything else on the SoC? Join Bryan as he talks about some of the ways Texas Instruments debugs and tunes their heterogeneous SoCs for Real-Time Linux workloads.
