TTBR1_EL2 mmu translation information wrong when E2H=1

lemin9538

I am now using DS5-studio to debug VHE feature, I set the page table of TTBR0_EL2 and TTBR1_EL2 to the same address, but from the mmu information of DS, they are not same, the memory type is not the same, the information from TTBR0_EL2 is right. It is some wrong in DS studio or there some thing I am missing when set the page table?

mmu information

    Hi Stephen,

    Good to know that. Thanks.

    My code runs good under ARMv8.0, But when I enable VHE (HCR_EL2.E2H = 1), The Guest VM can not boot successfully, and the Guest Linux will hang with access a strange address, so currently I am not sure whether this is caused by my hypervisor code or caused by the DS studio.

    Thanks
