Hi Carsten,
I checked this on N1SDP and I get failures in both threads tests. This is
because it's looking for "CID=..." when in my output threads are shown as
"VMID=...":
Idx:628048; ID:10; I_ADDR_CTXT_L_64IS0 : Address & Context, Long, 64 bit, IS0.; Addr=0x0000AAAAE3BF0B18; Ctxt: AArch64,EL0, NS; VMID=0xa588c;
I think with a change to the grep it should work.
Thanks
James
