i386: Introduce SnowRidge CPU model
SnowRidge CPU supports Accelerator Infrastrcture Architecture (MOVDIRI, MOVDIR64B), CLDEMOTE and SPLIT_LOCK_DISABLE. MOVDIRI, MOVDIR64B, and CLDEMOTE are found via CPUID. The availability of SPLIT_LOCK_DISABLE is check via msr access References can be found in either: https://software.intel.com/en-us/articles/intel-sdm https://software.intel.com/en-us/download/intel-architecture-instruction-set-extensions-and-future-features-programming-reference Signed-off-by: Paul Lai <paul.c.lai@intel.com> Tested-by: Tao3 Xu <tao3.xu@intel.com> Message-Id: <20190626162129.25345-1-paul.c.lai@intel.com> [ehabkost: squashed SPLIT_LOCK_DETECT patch] Message-Id: <20190626163232.25711-1-paul.c.lai@intel.com> Signed-off-by: Eduardo Habkost <ehabkost@redhat.com>
