[Qemu-devel] [PATCH qom-cpu for-1.5 4/4] target-i386: Change CPUID model of 486 to 8

[Andreas Färber]

This changes the model number of 486 to 8 (DX4) which matches the
feature set presented, and actually has the CPUID instruction.

This adds a compatibility property, to keep model=0 on pc-*-1.4 and older.
