Now my brain hurts....
Ok, so I read this as: ppc, ia64 and s390 can start with slot 0 and
it is not a special slot.
On x86 slot 0 is special, if
* KVM_CAP_SET_TSS_ADDR is not available
or
* The ioctl VM_CAP_SET_TSS_ADDR returns <=0
I think this is right. Izik can you confirm?
yea kernels that dont have KVM_CAP_SET_TSS_ADDR should be treated like that.
+#if defined(__x86_64__) || defined(__i386__)
+#if defined(KVM_CAP_SET_TSS_ADDR)
+ if (ioctl(kvm->fd, KVM_CHECK_EXTENSION, KVM_CAP_SET_TSS_ADDR) > 0)
Should be <= here?
+ i++;
+#else
+ i++;
+#endif
+#endif
Suggest a helper, kvm_supports_set_tss_addr(), to reduce further
braindamage.
