2012-11-22score: PR1607: Add and use CPU_SIZEOF_POINTERSebastian Huber1-0/+2
Add and use new CPU port define CPU_SIZEOF_POINTER. It must be an integer literal that can be used by the assembler. This value will be used to calculate offsets of structure members. These offsets will be used in assembler code. The size of a pointer is part of the application binary interface (ABI) and thus independent of the actual programming language. The compiler will provide defines to determine the current ABI. We use these defines to select the appropriate CPU_SIZEOF_POINTER value. Static assertions in the new file "cpukit/score/src/percpuasm.c" will ensure that the value of CPU_SIZEOF_POINTER is consistent with the current compiler settings. Also the offset values used by assembler code are verfied.

2012-05-11Remove All CVS Id Strings Possible Using a ScriptJoel Sherrill1-2/+0
Script does what is expected and tries to do it as smartly as possible. + remove occurrences of two blank comment lines next to each other after Id string line removed. + remove entire comment blocks which only exited to contain CVS Ids + If the processing left a blank line at the top of a file, it was removed.

This adds an allocated array of the Per_CPU structures to support multiple cpus vs a single instance of the structure which is still used if SMP support is disabled. Configuration support is also added to explicitly enable or disable SMP. But SMP can only be enabled for the CPUs which will support it initially -- SPARC and i386. With the stub BSP support, a BSP can be run as a single core SMP system from an RTEMS data structure standpoint. * aclocal/check-smp.m4, aclocal/enable-smp.m4, score/include/rtems/bspsmp.h, score/include/rtems/score/smplock.h, score/src/smp.c, score/src/smplock.c: New files.

* rtems/score/cpu.h: Define _CPU_Interrupt_stack_setup() macro which reserves space for the 'vector' arg to _C_dispatch_isr() routine and aligns the irq stack to CPU_STACK_ALIGNMENT.

* rtems/score/cpu.h: Replaced misleading typedef of CPU_Interrupt_frame by 'void'. The i386 port does not pass any frame info to the interrupt handlers.

* score/cpu/i386/rtems/score/cpu.h: Added #ifdef ASM constructs so that this header can be included from assembly code. Increased CPU_STACK_ALIGNMENT to 16 bytes. Gcc maintains 16-byte alignment and it may be a advantageous to provide initial 16-byte alignment. When using SSE some gcc versions may produce code that crashes if the stack is not 16-byte aligned. Make sure _CPU_Context_Initialize() sets the thread stack up so that it is aligned to CPU_CACHE_ALIGNMENT. * score/cpu/i386/cpu_asm.S: Align stack to CPU_CACHE_ALIGNMENT before calling C-code.

* rtems/score/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/score/cpu.h: Increase default stack size on i386 from 1K to 4K. Most i386 targets are not memory strapped so making this a bit large is not a burden. It lets more tests run. ticker and psxtimer will not even run with 1K of stack.

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.

2000-07-26Port of RTEMS to the Texas Instruments C3x/C4x DSP families includingJoel Sherrill1-0/+1
a BSP (c4xsim) supporting the simulator included with gdb. This port was done by Joel Sherrill and Jennifer Averett of OAR Corporation. Also included with this port is a space/time optimization to eliminate FP context switch management on CPUs without hardware or software FP. An issue with this port was that sizeof(unsigned32) = sizeof(unsigned8) on this CPU. This required addressing alignment checks and assumptions as well as fixing code that assumed sizeof(unsigned32) == 4.

1999-11-05This is another pass at making sure that nothing outside the BSPJoel Sherrill1-0/+15
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>.
