three intercore interrupts,internuclear IRQs is insufficient, how to deal with this

前提：

多核OS：使用了INT0_IRQ,INT1_IRQ,INT2_IRQ

IPCF也需要使用INT0_IRQ,INT1_IRQ

这个该如何处理呢，核间IRQ数量不够

Multi-core OS: INT0_IRQ,INT1_IRQ, and INT2_IRQ are used

IPCF also needs to use INT0_IRQ,INT1_IRQ

So what do we do about that? We don't have enough internuclear IRQ

Hi,

This is a HW restriction under the S32G2 platform. We don't see plans on increasing them, we do apologize.

If required, S32G3 adds up-to 12 internuclear IRQ.

Please, let us know.

If we want to use multi-core OS and IPCF, is it only possible for IPCF to use the query mode? In addition, can M core and A core use PFE to replace IPCF for inter-core communication

Hi,

For IPCF we are not seeing any re-configuration that could be done to modify the operating mode. As for using PFE for Core-to-Core communication, we are not seeing any documentation on this regard, all Core-to-Core communications are recommended with IPCF. We do apologize.

Please, let us know.
