Enable machine check exceptions by default, just like r204913 for amd64. Enable superpage promotion only if the processor actually supports large pages, i.e., PG_PS. MFC after: 2 weeks |

| H A D | specialreg.h | diff 204907 Tue Mar 09 01:44:18 MST 2010 alc Implement AMD's recommended workaround for Erratum 383 on Family 10h processors. With this workaround, superpage promotion can be re-enabled under virtualization. Moreover, machine check exceptions can safely be enabled when FreeBSD is running natively on Family 10h processors. Most of the credit should go to Andriy Gapon for diagnosing the error and working with Borislav Petkov at AMD to document it. Andriy also reviewed and tested my patches.

| H A D | subr_param.c | diff 204420 Sat Feb 27 16:06:46 MST 2010 alc When running as a guest operating system, the FreeBSD kernel must assume that the virtual machine monitor has enabled machine check exceptions. Unfortunately, on AMD Family 10h processors the machine check hardware has a bug (Erratum 383) that can result in a false machine check exception when a superpage promotion occurs. Thus, I am disabling superpage promotion when the FreeBSD kernel is running as a guest operating system on an AMD Family 10h processor. Reviewed by: jhb, kib MFC after: 3 days |

| H A D | pmap.c | diff 265554 Wed May 07 13:54:32 MDT 2014 alc MFC r262338 When the kernel is running in a virtual machine, it cannot rely upon the processor family to determine if the workaround for AMD Family 10h Erratum 383 should be enabled. To enable virtual machine migration among a heterogeneous collection of physical machines, the hypervisor may have been configured to report an older processor family with a reduced feature set. Effectively, the reported processor family and its features are like a "least common denominator" for the collection of machines. Therefore, when the kernel is running in a virtual machine, instead of relying upon the processor family, we now test for features that prove that the underlying processor is not affected by the erratum. (The features that we test for are unlikely to ever be emulated in software on an affected physical processor.)
