Subject: target/i386: Add the 'model-id' for Skylake -v3 CPU models
X-Git-Tag: qemu-xen-4.14.0~177^2~1
X-Git-Url: http://xenbits.xensource.com/gitweb?a=commitdiff_plain;h=673b0add9ea7f432f34c1c99eaa7c567012fc838;p=qemu-xen.git

target/i386: Add the 'model-id' for Skylake -v3 CPU models

This fixes a confusion in the help output.  (Although, if you squint
long enough at the '-cpu help' output, you _do_ notice that
"Skylake-Client-noTSX-IBRS" is an alias of "Skylake-Client-v3";
similarly for Skylake-Server-v3.)

Without this patch:

    $ qemu-system-x86 -cpu help
    ...
    x86 Skylake-Client-v1     Intel Core Processor (Skylake)
    x86 Skylake-Client-v2     Intel Core Processor (Skylake, IBRS)
    x86 Skylake-Client-v3     Intel Core Processor (Skylake, IBRS)
    ...
    x86 Skylake-Server-v1     Intel Xeon Processor (Skylake)
    x86 Skylake-Server-v2     Intel Xeon Processor (Skylake, IBRS)
    x86 Skylake-Server-v3     Intel Xeon Processor (Skylake, IBRS)
    ...

With this patch:

    $ ./qemu-system-x86 -cpu help
    ...
    x86 Skylake-Client-v1     Intel Core Processor (Skylake)
    x86 Skylake-Client-v2     Intel Core Processor (Skylake, IBRS)
    x86 Skylake-Client-v3     Intel Core Processor (Skylake, IBRS, no TSX)
    ...
    x86 Skylake-Server-v1     Intel Xeon Processor (Skylake)
    x86 Skylake-Server-v2     Intel Xeon Processor (Skylake, IBRS)
    x86 Skylake-Server-v3     Intel Xeon Processor (Skylake, IBRS, no TSX)
    ...
