2014-02-14score: Add CPU counter supportSebastian Huber1-0/+1
Add a CPU counter interface to allow access to a free-running counter. It is useful to measure short time intervals. This can be used for example to enable profiling of critical low-level functions. Add two busy wait functions rtems_counter_delay_ticks() and rtems_counter_delay_nanoseconds() implemented via the CPU counter.
2014-02-06bsp/leon3: Declare bsp_debug_uart_init() in headerSebastian Huber1-1/+1
Do not return a status.

2012-02-02LEON3: change d-cache snoop detect implementationDaniel Hellstrom1-5/+5
PR 2010/bsps The previous code only checked if d-cache snooping was implemented, however snooping may be available but not enabled which may lead to driver bugs. Signed-off-by: Daniel Hellstrom <daniel@gaisler.com>

2012-02-02LEON3: CPU index intialization moved to bspstart.cDaniel Hellstrom1-0/+18
PR 2009/bsps All LEON3/4 systems have a CPU-id, if on a single-CPU system the ID is always zero. On a multicore system it ranges from 0 to 15. The CPU index should always by updated even in a non-MP RTEMS OS since the CPU running RTEMS may not always be CPU0. For example when RTEMS runs on CPU1 and Linux on CPU0 in a mixed ASMP system. The old code executed within the IRQ controller initialization code makes no sense since the ASR register is a CPU register, it has nothing to do with AMBA initialization either.

* amba/amba.c, include/tm27.h, shmsupp/lock.c, startup/bspstart.c, startup/spurious.c: Use "__asm__" instead of "asm" for improved c99-compliance.
2010-05-242010-05-24 Joel Sherrill <joel.sherrill@oarcorp.com>Joel Sherrill1-0/+5
* Makefile.am, amba/amba.c, console/console.c, console/debugputs.c, startup/bspstart.c: Rework initialization order so AMBA bus is scanned earlier. This lets us look for UARTs earlier and support printk as early as bsp_start() returning.

* Makefile.am, startup/bspstart.c: Use ../../sparc/shared/bsppretaskinghook.c. * console/console.c: Remove sis comment.
2008-09-152008-09-14 Joel Sherrill <joel.sherrill@oarcorp.com>Joel Sherrill1-32/+0
* Makefile.am, startup/bspstart.c: Use shared bsp_get_work_area() into its own file and use BSP Framework to perform more initialization.
2008-08-18Remove bogus local declarations.Ralf Corsepius1-6/+3
2008-07-24Changed bsp_get_workarea() to bsp_get_work_area() andThomas Doerfler1-7/+10
added support for an optional separate heap area.
2008-05-152008-05-15 Joel Sherrill <joel.sherrill@OARcorp.com>Joel Sherrill1-39/+29
* Makefile.am, configure.ac, startup/bspstart.c: Add capability for bootcard.c BSP Initialization Framework to ask the BSP where it has memory for the RTEMS Workspace and C Program Heap. These collectively are referred to as work area. If the BSP supports this, then it does not have to include code to split the available memory between the two areas. This reduces the amount of code in the BSP specific bspstart.c file. Additionally, the shared framework can initialize the C Library, call rtems_debug_enable(), and dirty the work area memory. Until most/all BSPs support this new capability, if the BSP supports this, it should call RTEMS_BSP_BOOTCARD_HANDLES_RAM_ALLOCATION from its configure.ac. When the transition is complete, this autoconf macro can be removed.
2008-05-122008-05-12 Joel Sherrill <joel.sherrill@OARcorp.com>Joel Sherrill1-3/+0
* startup/bspstart.c: Refactored and renamed initialization routines to rtems_initialize_data_structures, rtems_initialize_before_drivers, rtems_initialize_device_drivers, and rtems_initialize_start_multitasking. This opened the sequence up so that bootcard() could provide a more robust and flexible framework which is easier to explain and understand. This also lays the groundwork for sharing the division of available memory between the RTEMS workspace and heap and the C library initialization across all BSPs.

* clock/ckinit.c, include/bsp.h, startup/bspstart.c: Eliminate copies of the Configuration Table. Use the RTEMS provided accessor macros to obtain configuration fields.
2007-12-042007-12-04 Joel Sherrill <joel.sherrill@OARcorp.com>Joel Sherrill1-7/+0
* amba/amba.c, clock/ckinit.c, console/console.c, include/bsp.h, startup/bspstart.c, timer/timer.c: Move interrupt_stack_size field from CPU Table to Configuration Table. Eliminate CPU Table from all ports. Delete references to CPU Table in all forms.
2007-12-032007-12-03 Joel Sherrill <joel.sherrill@OARcorp.com>Joel Sherrill1-12/+1
* amba/amba.c, startup/bspstart.c: 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.
2007-09-062007-09-05 Daniel Hellstrom <daniel@gaisler.com>Joel Sherrill1-0/+27
* include/bsp.h, startup/bspstart.c: LEON2 and LEON3 Data cache snooping detection on startup, for drivers. (LEON2,3 are configurable processors, they can be with or without DCache snooping. Caches without snooping needs the drivers to flush cache or use the sparc instruction lda to force cache miss...)

* include/bsp.h, startup/bspstart.c, startup/spurious.c: hello and ticker now run using runtest.

* console/debugputs.c, include/bsp.h, leon_smc91111/leon_smc91111.c, startup/bspstart.c, startup/spurious.c: Remove debug print methods that are redundant with prntk and replace their use with printk.
2007-03-112007-03-11 Joel Sherrill <joel@OARcorp.com>Joel Sherrill1-7/+0
* startup/bspstart.c: Remove assignments of Cpu_table.do_zero_of_workspace to TRUE since TRUE is the default value in boot_card.c
2006-11-162006-11-16 Joel Sherrill <joel@OARcorp.com>Joel Sherrill1-106/+1
* clock/ckinit.c, startup/bspstart.c: Use common clock driver template and eliminate all fast idle code specific to this BSP. This eliminates a fair amount of code in the BSP clock driver and bsp_startup. The LEON3 has to do a scan of the AMBA bus to find the timer so I added the new hook Clock_driver_support_find_timer to support this. In general, there was some clean up to the file headers of various files.

1999-11-17Updated copyright notice.Joel Sherrill1-1/+1
1998-04-30Removed tripling of workspace API when POSIX API is enabled. confdefs.hJoel Sherrill1-1/+3
is now correct enough where this is not necessary. This was in to cover up the deficiencies in figuring out how much memory a GNAT/RTEMS application required. There is a good stab at this now.
1998-04-18psim now runs in both debug and non-debug mode.Joel Sherrill1-4/+3
1998-04-15Numerous changes which in total greatly reduced the amount of sourceJoel Sherrill1-28/+4
code in each BSP's bspstart.c. These changes were: + confdefs.h now knows libio's semaphore requirements + shared/main.c now copies Configuration to BSP_Configuration + shared/main.c fills in the Cpu_table with default values This removed the need for rtems_libio_config() and the constant BSP_LIBIO_MAX_FDS in every BSP. Plus now the maximum number of open files can now be set on the gcc command line.
