[Qemu-devel] [PULL v6 08/12] pc: Improve error message when die-id is om


From: Eduardo Habkost
Subject: [Qemu-devel] [PULL v6 08/12] pc: Improve error message when die-id is omitted
Date: Wed, 28 Aug 2019 15:40:22 -0300

The error message when die-id is omitted doesn't make sense:

  $ qemu-system-x86_64 -smp 1,sockets=6,maxcpus=6 \
    -device qemu64-x86_64-cpu,socket-id=1,core-id=0,thread-id=0
  qemu-system-x86_64: -device 
qemu64-x86_64-cpu,socket-id=1,core-id=0,thread-id=0: \
    Invalid CPU die-id: 4294967295 must be in range 0:0

Fix it, so it will now read:

  qemu-system-x86_64: -device 
qemu64-x86_64-cpu,socket-id=1,core-id=0,thread-id=0: \
    CPU die-id is not set
