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.

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

P.S. discussed internally here Vybrid SGI implementation and SGI configuration on Vybrid
