[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [Xen-devel] [PATCH RFC 02/31] tools/libxc: Use public/featureset.h for cpuid policy generation
Rather than having a different local copy of some of the feature definitions. Modify the xc_cpuid_x86.c cpumask helpers to appropriate truncate the new values, and add X86_FEATURE_TSC_ADJUST to the public API to allow libxc to continue compiling.
