Qualcomm SoCs runnning with Qualcomm EL2 hypervisor(QHEE), IOMMU
translation set up for remote processors is managed by QHEE itself
however, for a case when these remote processors has to run under KVM

This is not true, KVM is a Linux hypervisor, remote processors have
nothing to do with KVM, please rephrase.

Thanks, perhaps something like this,

"However, when same SoC runs with KVM configuration, remoteproc IOMMU
translation needs to be set from Linux host running remoteproc PAS
driver"

Thanks but I still don't see what KVM has to do here, KVM is an an optional
Linux kernel feature, Linux can be configured without KVM and still perfectly
startup those remoteprocs.
