Disable the SGI.

[takashitakahash]

Hi community.

Our customer would like to disable the SGI.

In the current Integrity OS, SGI( Software-generated Interrupts) is enabled by default.

For SGI is not used in customer system, we want to disable.

Would you advice should be disabled in any such a procedure?

If you have any sample software I think want me to reference.

Hi,

this looks like a question for Green Hills (developer of INTEGRITY RTOS).

Hello Takashi-san,

this has  been discussed with Taku-san. It is depended on design of SoC (based on implementation or ARM GIC). It is not possible to disable SGI separately.

You can

- disable all interrupts or

- do not assert software interrupts
