This causes some software such as LLVM to notice the problem (32-bit cpu with 64-bit capability reported in the cpuid flag) and produce various error messages. The simple solution would be to upgrade this definition to use the Sledgeha= mmer family (15) instead. = [1] https://en.wikipedia.org/wiki/List_of_AMD_CPU_microarchitectures ** Affects: qemu Importance: Undecided Status: New -- = You received this bug notification because you are a member of qemu- devel-ml, which is subscribed to QEMU. https://bugs.launchpad.net/bugs/1860575 Title: qemu64 CPU model is incorrect Status in QEMU: New Bug description: At the moment the "qemu64" CPU is defined as follows: ``` .vendor =3D CPUID_VENDOR_AMD, .family =3D 6, .model =3D 6, .stepping =3D 3, ``` According to Wikipedia [1] this means the CPU is defined as part of the K7 family while the AMD64 ISA was only introduced with the K8 series!
