I am hitting the below failure with v6.15 (I tried other kernel versions
with similar results). I disabled CONFIG_PROTECTED_NVHE_STACKTRACE
because with CONFIG_NVHE_EL2_DEBUG, the stack was pointing at
hyp_assert_lock_held() .

I was able to locate a .config that make the pkvm work, But i am not
able to identify which config dependency is making the difference. I am
attaching below the working and non working kernel configs. I am using
FVP to test this.

Why do you get different results based on the backtrace support?

ESR_EL2 shows that this is a S1 translation fault, level 3, from
EL2. This is consistent with hitting the BUG() in handle_trap(().
What is at this PC?

FAR_EL2 is valid (as per the above), so what is EL2 trying to access
at this address?

If you're using a model, it should be pretty easy to track all of the
above.

I had a look at this and tracked the issue to "CONFIG_JUMP_LABEL=n"
It seems that it panics at
if (static_branch_unlikely(&kvm_protected_mode_initialized))
Where "kvm_protected_mode_initialized" is mapped in the initial PGD for the
hypervisor, but not mapped in the hypervisor created one.
As the variable is defined outside the hypervisor namespace, it doesn’t exist
in the hyp bss section.
And in case of "CONFIG_JUMP_LABEL=n" it won't be patched in this case, causing
next access to read the variable and panicking.
I guess moving this key to hyp would cause problems with kernel access after
de-privilege as cases from kvm_share_hyp(), So I can only think of having a
different key for the hypervisor as

There are other references to kvm_protected_mode_initialized within
nvhe. Shouldn't all of those be updated as well?
Also, do we need to drop this line?
KVM_NVHE_ALIAS(kvm_protected_mode_initialized);
If I understand correctly, nvhe will now have a separate static key,
distinct from the one used by the EL1 host. So we'll need to update
functions like is_pkvm_initialized() and host_data_ptr() accordingly,
right?

It really begs the question: why do we even support JUMP_LABEL=n? It
really feels like a backward configuration, and I'd be very glad to
either mark it as "always on", or make KVM depend on it.

I don't really enjoy this duplication, and unless we have a good
reason not too, I'd rather have something like:

It should be OK now that all the supported compilers have asm goto

Yes, I missed the ones in the headers, those should be replaced with
“kvm_protected_mode_initialized_hyp” also.

Yes, that’s not needed now.

As far as I see, those are used by the kernel only, but if needed we can
guard that with “__KVM_NVHE_HYPERVISOR__”
host_data_ptr() won’t access the key from the hypervisor because of the
macro check.
But I agree with Marc, that is a lot of duplication.

Yes, that looks better, I am not sure why that is not automatically
selected. AFAIK, it should be ok atleast for arm64.
There are some hidden problems though, if the condition is false, that
would panic after de-privilege, but as the key is toggled at
pkvm_drop_host_privileges() before the privilege drop, it should be fine
for now. (but not if the code is reworked)
Also, ofcourse static_branch_disable() won’t be supported.
I’d say, we can add a comment explaining that this key can't be read from
the hypervisor from memory, in case someone reworked this in the future.
