Add a "unavailable-features" QOM property to X86CPU objects that
|
|
|
4ec855 |
have the same semantics of "unavailable-features" on
|
|
|
4ec855 |
query-cpu-definitions. The new property has the same goal of
|
|
|
4ec855 |
"filtered-features", but is generic enough to let any kind of CPU
|
|
|
4ec855 |
feature to be listed there without relying on low level details
|
|
|
4ec855 |
like CPUID leaves or MSR numbers.
