[Qemu-devel] [PATCH 0/4] target-i386: Don't try to enable unsupported TCG features by default

[Eduardo Habkost]

This series makes QEMU stop trying to enable an unsupported feature by default
in TCG mode, avoiding the warnings shown by the (now enabled by default)
"check" mode.

To do that, I cchanged the kvm_default_features code to be based on QOM
properties, and added a new "type" field to allow per-CPU-model KVM defaults to
be specified.

Before this series:

  $ qemu-system-x86_64 -S
  warning: TCG doesn't support requested feature: CPUID.01H:EDX.de [bit 2]
  warning: TCG doesn't support requested feature: CPUID.80000001H:EDX [bit 2]

After this series:

  $ ./x86_64-softmmu/qemu-system-x86_64 -S
  [no warning output]

Eduardo Habkost (4):
  target-i386: Expand PPRO_FEATURES on qemu64/qemu32 definitions
  target-i386: Convert kvm_default_*features to property/value pairs
  target-i386: Add optional class name to kvm_default_props
  target-i386: Disable DE on qemu64 & qemu32 on TCG
