[Qemu-devel] [PATCH v2 0/4] x86 CPU model fixes


From: Paolo Bonzini
Subject: [Qemu-devel] [PATCH v2 0/4] x86 CPU model fixes
Date: Wed, 10 Dec 2014 12:06:28 +0100

Most processors were lacking the VME flags.  Haswell and Broadwell were
lacking two more.  And Ivy Bridge was missing altogether.

Family/model/stepping for a low-end Xeon E3 v2 found on the address@hidden CPU
list (http://setiathome.berkeley.edu/cpu_list.php), they also match the
Ivy Bridge Core i7 processor on which I tested the patch.  The following
bare-metal features are missing in the guest:

    dts acpi ss ht tm pbe arch_perfmon pebs bts xtopology nonstop_tsc
    aperfmperf dtes64 monitor ds_cpl vmx smx est tm2 xtpr pdcm ida
    arat epb pln pts dtherm tpr_shadow vnmi flexpriority ept vpid

... the absence of none of which is surprising.

v1->v2:
        add pc_compat_2_2 call to pc_compat_2_1 (for both PC and Q35)
        remove VME, do not add it, for 2.2 machines
        remove F16C/RDRAND, do not add them, for 2.2 machines
        do not touch model names for SandyBridge

Paolo Bonzini (4):
  pc: add 2.3 machine types
  target-i386: add VME to all CPUs
  target-i386: add f16c and rdrand to Haswell and Broadwell
  target-i386: add Ivy Bridge CPU model
