Hi, david
I read your patch and find this:
+#define KVM_TRC_PTE_WRITE (KVM_TRC_HANDLER +
0x15)
+#define KVM_TRC_PTE_FLOODED (KVM_TRC_HANDLER +
0x16)
but in your formats file
+0x00020015 %(tsc)d (+%(reltsc)8d) PTE_FLOODED vcpu
= 0x%(vcpu)08x pid = 0x%(pid)08x
+0x00020016 %(tsc)d (+%(reltsc)8d) PTE_WRITE vcpu
= 0x%(vcpu)08x pid = 0x%(pid)08x [ gpa = 0x%(2)08x %(1)08x gpte =
0x%(4)08x %(3)08x ]
You mistake the value, right?
