In x86, the functions calls to apic functions. *kern/smp.c: Source file. Implements a interface to load the SMP functions for the current architecture. *kern/smp.h: Header file. Add declaration for smp_data structure. *i386/i386/smp.c: Source file. Implements a set of functions to manage the SMP actions in i386 *i386/i386/smp.h: Header file. Add declarations for SMP functions in i386. --- kern/smp.h | 24 ++++++++++++++++++++++++ 1 file changed, 24 insertions(+) create mode 100644 kern/smp.h (limited to 'kern/smp.h') diff --git a/kern/smp.h b/kern/smp.h new file mode 100644 index 00000000..44e96f39 --- /dev/null +++ b/kern/smp.h @@ -0,0 +1,24 @@ +/* smp.h - Template for generic SMP controller for Mach.
