Subject: Help on kvm_tlb_flush_vmid_ipa usage
Date: Thu, 18 Dec 2014 11:27:19 -0800 [thread overview]
Message-ID: <54932A97.3060103@samsung.com> (raw)
When this function is called IPA address is used.
Looking at the HYP implementation it uses the IPA
directly in tlbi instructions. But reading the TLB maintnance
instruction syntax, bit [35:0] should be set to
IPA[47:12]. I traced the source code but don't see
the adjustment. I must be missing something
given this function is fundamental to KVM MMU.
Thanks,
Mario
