TDA4VM: [GIC] SGI ID13 (or just 8-15) is unavailable for our multiple OS communication (Linux kernel version 5.10 and a determinism RTOS)

Part Number: TDA4VM

In our environment (Machine model: Texas Instruments K3 J721E SoC), SGI ID13 is unavailable for our multiple VMs communication. Our OS is Linux (kernel version 5.10 git://git.ti.com/ti-linux-kernel/ti-linux-kernel.git and UBoot is git://git.ti.com/ti-u-boot/ti-u-boot.git, SDK is ti-processor-sdk-linux-j7-evm-08_01_00_07) and a rtos (determinism OS). We want to know if it's possible to use SGI ID8-15 in multiple VMs communication like this Scenes.

Hi,

There is NO support for virtualization on the TDA4VM SDK.

By my word VMs, I don't mean virtualization, just running multiple OSs simultaneously on a hardware environment (just like OS1 running on core 0 and OS2 running on core1). I want to know if it's possible to use SGI ID8-15 in multiple OS communication (or not support 8-15 and need use tad4 mailbox).

Running OS1 on core 0 & OS2 on core 1 is NOT supported.

It has been descoped since SDK 7.0.

Okay, thank you. So can we use mailbox for communications in this scenario?

We do not have support for booting 2 OS. If you want to communicate between firmware running on different cores mailbox can be used.
