PROCESSOR-SDK-J784S4: linux-rt performance guide / cyclictest results

Daniel Braunwarth

Tool/software:

I've found cyclictest results for the AM64X variant here:

https://software-dl.ti.com/processor-sdk-linux-rt/esd/AM64X/latest/exports/docs/devices/AM64X/linux/RT_Linux_Performance_Guide.html?highlight=cyclictest#stress-ng-and-cyclic-test

Is this also available for the J784s4?

Daniel,

We do not have the rt-linux SDK for j784s4.

We only have Linux/RTOS/QNX:

So we do not have numbers for rt-linux.

Best Regards,

Hi Keerthy

OK. This means the SoC and/or the SDK is not realtime capable?

We are not using the SDK directly but cloning the Git repository and using the Linux kernel "-rt" branch. If this is not realtime capable - why is it here?

Daniel

Hi Daniel,

SoC is capable. SDK we do not have the rt-Linux version.

This could be used for real time capability. I checked internally that rt- branch can be used on j784s4.
