Hello, Today, the inter chip communication for interrupts uses the pnv_xive_get_remote() routine to grab the remote XIVE interrupt controller object. This is a modeling shortcut which can be improved by implementing :
* remote END triggers * memory operations on remote NVT structures. Both are addressed by this series for P9. P10 should be similar. Thanks, C.
