From f068384e3c8fd31d4791e22b4c91e29fa907ff3b Mon Sep 17 00:00:00 2001 From: Sebastian Huber Date: Wed, 24 Jul 2013 12:03:31 +0200 Subject: score: Create schedulerpriority impl header Move implementation specific parts of schedulerpriority.h and schedulerpriority.inl into new header file schedulerpriorityimpl.h. The schedulerpriority.h contains now only the application visible API. Add missing includes. Remove superfluous includes. Move declaration of _Priority_Bit_map to prioritybitmap.inl since this variable is used only here. Remove second declaration of _Priority_Major_bit_map. --- cpukit/score/inline/rtems/score/prioritybitmap.inl | 5 + .../score/inline/rtems/score/schedulerpriority.inl | 210 --------------------- 2 files changed, 5 insertions(+), 210 deletions(-) delete mode 100644 cpukit/score/inline/rtems/score/schedulerpriority.inl (limited to 'cpukit/score/inline/rtems/score') diff --git a/cpukit/score/inline/rtems/score/prioritybitmap.inl b/cpukit/score/inline/rtems/score/prioritybitmap.inl index 70844fa0e3..19196ceea2 100644 --- a/cpukit/score/inline/rtems/score/prioritybitmap.inl +++ b/cpukit/score/inline/rtems/score/prioritybitmap.inl @@ -97,6 +97,11 @@ RTEMS_INLINE_ROUTINE uint32_t _Priority_Bits_index ( * Priority Queue implemented by bit map */ +/** + * This is the minor bit map. + */ +extern Priority_bit_map_Control _Priority_Bit_map[16] CPU_STRUCTURE_ALIGNMENT;
