--------------------
|
|
01e,30mar10,cww Added _ASMLANGUAGE protection
|
|
01d,25jan10,d_c SMP M-N updates: Add CPU_LOGICAL_TO_PHYS and
|
|
CPU_PHYS_TO_LOGICAL macros. Add cpuid_t type.
|
|
Add extern of vxBaseCpuPhysIndex.
|
|
01c,02feb09,cww Add dynamic CPU reservation API
|
|
01b,25oct06,lei moved macros to private/vxCpuLibP.h
|
|
01a,05jul06,mmi Created based on ../i86/vxCpuLib.h
