Right it's not necessary. I think it can be reported as:
case KVM_CAP_MAX_VCPUS:
r = KVM_MAX_VCPUS;
+ if (kvm)
+ r = kvm->max_vcpus;
break;

Actually later versions of TDX module (starting from 1.5 AFAICT), the
module has a metadata field to report the maximum vCPUs that the module
can support for all TDX guests.

Yeah the above could be helpful, but might not be necessary.
So the logic of updated patch is:
1) During module loading time, we grab the maximum vCPUs that the TDX
module can support:
/kvm_vm_ioctl_enable_cap
* TDX module may not support MD_FIELD_ID_MAX_VCPUS_PER_TD
* depending on its version.
*/
tdx_info->max_vcpus_per_td = U16_MAX;
if (!tdx_sys_metadata_field_read(MD_FIELD_ID_MAX_VCPUS_PER_TD,
&tmp))
tdx_info->max_vcpus_per_td = (u16)tmp;
2) When TDX guest is created, the userspace needs to call
IOCTL(KVM_ENABLE_CAP) to configure the maximum vCPUs of the guest. A
new kvm_x86_ops::vm_enable_cap() is added because TDX has it's own
limitation (metadata field) as mentioned above.
@@ -6827,6 +6829,8 @@ int kvm_vm_ioctl_enable_cap(struct kvm *kvm,
}
default:
r = -EINVAL;
+ if (kvm_x86_ops.vm_enable_cap)
+ r = static_call(kvm_x86_vm_enable_cap)(kvm,
+ cap);
And we only allow the kvm->max_vcpus to be updated if it's a TDX guest
in the vt_vm_enable_cap(). The reason is we want to avoid unnecessary
change for normal VMX guests.
And the new kvm->max_vcpus cannot exceed the KVM_MAX_VCPUS and the
tdx_info->max_vcpus_per_td:
+ case KVM_CAP_MAX_VCPUS: {

+ else {
+ kvm->max_vcpus = cap->args[0];
+ r = 0;
+ }
+ mutex_unlock(&kvm->lock);
+ break;
+ }
3) We just report kvm->max_vcpus when the userspace wants to check the
KVM_CAP_MAX_VCPUS as shown in the beginning of my reply.
Does this make sense to you?
I am also pasting the new updated patch for your review (there are line
wrapper issues unfortunately due to the simple copy/paste):

Subject: [PATCH] KVM: TDX: Allow userspace to configure maximum vCPUs
for TDX guests
TDX has its own mechanism to control the maximum number of vCPUs that
the TDX guest can use. When creating a TDX guest, the maximum number of
vCPUs of the guest needs to be passed to the TDX module as part of the
measurement of the guest. Depending on TDX module's version, it may
also report the maximum vCPUs it can support for all TDX guests.
Because the maximum number of vCPUs is part of the measurement, thus
part of attestation, it's better to allow the userspace to be able to
configure it. E.g. the users may want to precisely control the maximum
number of vCPUs their precious VMs can use.
The actual control itself must be done via the TDH.MNG.INIT SEAMCALL,
where the number of maximum cpus is part of the input to the TDX module,
but KVM needs to support the "per-VM maximum number of vCPUs" and
reflect that in the KVM_CAP_MAX_VCPUS.
Currently, the KVM x86 always reports KVM_MAX_VCPUS for all VMs but
doesn't allow to enable KVM_CAP_MAX_VCPUS to configure the number of
maximum vCPUs on VM-basis.
Add "per-VM maximum number of vCPUs" to KVM x86/TDX to accommodate TDX's
needs.
Specifically, use KVM's existing KVM_ENABLE_CAP IOCTL() to allow the
userspace to configure the maximum vCPUs by making KVM x86 support
enabling the KVM_CAP_MAX_VCPUS cap on VM-basis.
For that, add a new 'kvm_x86_ops::vm_enable_cap()' callback and call
it from kvm_vm_ioctl_enable_cap() as a placeholder to handle the
KVM_CAP_MAX_VCPUS for TDX guests (and other KVM_CAP_xx for TDX and/or
other VMs if needed in the future).
Implement the callback for TDX guest to check whether the maximum vCPUs
passed from usrspace can be supported by TDX, and if it can, override
Accordingly, in the KVM_CHECK_EXTENSION IOCTL(), change to return the
'struct kvm::max_vcpus' for a given VM for the KVM_CAP_MAX_VCPUS.

v20:
- Drop max_vcpu ops to use kvm.max_vcpus
- Remove TDX_MAX_VCPUS (Kai)
- Use type cast (u16) instead of calling memcpy() when reading the
'max_vcpus_per_td' (Kai)
- Improve change log and change patch title from "KVM: TDX: Make
KVM_CAP_MAX_VCPUS backend specific" (Kai)
