Macros which were not used by cpukit have been moved to libcpu/powerpc/rtems/powerpc/powerpc.h.

* rtems/new-exceptions/cpu.h, rtems/old-exceptions/cpu.h: Moved most of the remaining CPU Table fields to the Configuration Table. This included pretasking_hook, predriver_hook, postdriver_hook, idle_task, do_zero_of_workspace, extra_mpci_receive_server_stack, stack_allocate_hook, and stack_free_hook. As a side-effect of this effort some multiprocessing code was made conditional and some style clean up occurred.

* rtems/new-exceptions/cpu.h: Per PR211 fix saving/restoring floating point context. The fpsave and fprestore routines are only used in a executing context which _is_ fp and hence has the FPU enabled. The current behavior required the FPU always to be on which is very dangerous if lazy context switching is used. [Joel Note: Some ports explicitly enabled the FPU in the FP save and restore routines to avoid this.] The patch also makes sure (on powerpc only) that the FPU is disabled for integer tasks. Note that this is crucial if deferred fp context switching is used. Otherwise, fp context corruption may go undetected! Also note that even tasks which merely push/pop FP registers to/from the stack without modifying them still MUST be FP tasks - otherwise (if lazy FP context switching is used), FP register corruption (of other, FP, tasks may occur)! Furthermore, (on PPC) by default, lazy FP context save/restore is _disabled_.

This was tracked as PR91. * rtems/score/cpu.h: Added CPU_PROVIDES_ISR_IS_IN_PROGRESS macro which is used to specify if the port uses the standard macro for this (FALSE). A TRUE setting indicates the port provides its own implementation. * rtems/score/c_isr.inl: Deleted and contents merged into cpu.c. * cpu.c: Received contents of c_isr.inl. * Makefile.am: Deleted reference to c_isr.inl.

1999-11-05This is another pass at making sure that nothing outside the BSPJoel Sherrill1-0/+9
unnecessarily uses any variables defined by the BSP. On this sweep, use of BSP_Configuration and Cpu_table was eliminated. A significant part of this modification was the addition of macros to access fields in the RTEMS configuration structures. This is necessary to strengthen the division between the BSP independent parts of RTEMS and the BSPs themselves. This started after comments and analysis by Ralf Corsepius <corsepiu@faw.uni-ulm.de>.
1999-11-04The files in libcpu should not be directly dependent on any BSP. InJoel Sherrill1-1/+4
particular, using bsp.h, or getting information from the BSP which should properly be obtained from RTEMS is forbidden. This is necessary to strengthen the division between the BSP independent parts of RTEMS and the BSPs themselves. This started after comments and analysis by Ralf Corsepius <corsepiu@faw.uni-ulm.de>. The changes primarily eliminated the need to include bsp.h and peeking at BSP_Configuration. The use of Cpu_table in each BSP needs to be eliminated.
