Hi all!I tried running Linux of ARM architecture by GEM5 v21.2.1.1 with feature 
`FEAT_VHE` and `VIRTUALIZATION` enabled, but it stalled in `paging_init`. The 
Linux is compiled from https://gem5.googlesource.com/arm/linux, branch 
`gem5/v4.14`; and the bootloader is `boot.arm64` downloaded from 
http://dist.gem5.org/dist/v21-2/arm/aarch-system-20210904.tar.bz2.


This problem is quite similar to https://gem5.atlassian.net/browse/GEM5-901.



I noticed that in GEM v20.1.0.3, a parameter `have_vhe` was added, in commit 
https://gem5-review.googlesource.com/c/public/gem5/+/39695. This parameter was 
removed in a later commit 
https://gem5-review.googlesource.com/c/public/gem5/+/51010.


Can GEM5 running Linux using Arm ISA with FEAT_VHE support?


Best Regards,


Yifan Tan
