RTOS/DRA746: SMP require use of gating

Part Number: DRA746
Other Parts Discussed in Thread: SYSBIOS

Tool/software: TI-RTOS

Received the following from our customer:

"In 'Proper default heap configuration for Sysbios', the resolution was to use the gate functionality within SMP and SYSBIOS.

It would seem that SYSBIOS would know if it’s operating in SMP mode, and apply the appropriate gate functions internally for OS resources (e.g. heap allocation), and not be dependent on user configuration.   

Of course another alternative is to let the black magic of configuro handle this, so that only “gate” enabled libraries are used when SYSBIOSis linked.

Do you agree with this assessment?  If so, is this being considered for future SYSBIOS (or xdc) releases?"

  • I did not follow all the questions, but, here's a response to the one I understand:

    That is true. As noted on the SMP/BIOS wiki page, all SYS/BIOS modules except LoggerBuf, SysMin & SysStd, are SMP aware and use gate providers that are SMP aware.
