* pc386: Add Edison base supportJoel Sherrill2015-01-0412-17/+220
| | | | | | | | | The current support for the Edison supports a single polled UART for input and output plus a simulated clock tick. The activities forward for supporting the Edison have been posted on the RTEMS mailing lists and at: http://rtemsramblings.blogspot.com/2014/12/intel-edison-and-rtems-road-forward.html
* pc386: Add BSP_ENABLE_COM1_COM4 BSP optionJoel Sherrill2015-01-043-27/+38
| | | | | | This allows the support for the legacy COM1-COM4 serial ports to be completely disabled. It is needed to prevent hangs on some hardware. In particular, the Intel Edison where it is not present.
* pc386: Add BSP_ENABLE_IDE BSP optionJoel Sherrill2015-01-044-1/+13
| | | | | | This allows the IDE support to be completely disabled. It is needed to prevent hangs on some hardware. In particular, the Intel Edison where it is not present.
* pc386: Add BSP_ENABLE_VGA BSP optionJoel Sherrill2015-01-047-36/+69
| | | | | | This allows the VGA and keyboard console to be completely disabled. It is useful on PCs without displays and prevents a very slow boot time on the Intel Edison.
* pc386: scan all functions of multi-function PCI devicesTill Strauman2014-12-231-7/+23
| | | | | | | | | | | | | | | | | | | The current algorithm scans all PCI busses (0..ff) and all devices (0..31) on each bus for bridges and determines the maximum of all subordinate busses encountered. However, the algorithm does not scan all functions present in multi-function devices -- I have a PCI express root complex (82801H) where multiple (non-zero index) functions are 'PCI bridges' whose subordinate bus number is missed by the original algorithm. This commit makes sure that the scan is extended to all functions of multi-function devices. See #2067

* libmisc: More useful default configurationSebastian Huber2014-12-051-1/+0
| | | | | | | | | | | The dummy.c was a de-facto default configuration. Rename it to default-configuration.c. Use unlimited objects and the stack checker. This makes it easier for new RTEMS users which will likely use this file if they just work with the usual main() function as the application entry point. Provide proper arguments for main() using the BSP command line. Add spare user extensions and drivers. Do not initialize the network by default. Delete bspinit.c.

* i386/pc386: cammelCase (struct and function names) to underscores, typedefed ↵Jan Dolezal2014-12-047-245/+250
| | | | | | | | | | structs, break >80 chars lines, removed newlines at EOFs fb_vesa_rm.c: removed inline from functions declared in fb_vesa.h removed unnecessary printks in the end of patch edid.h, vbe3.h: switched from custom *PACKED_ATTRIBUTE at the structs to the RTEMS_COMPILER_PACKED_ATTRIBUTE for easier maintainability of doxygen
* pc386 bsp fix for default modeBen Gras2014-12-031-2/+2
| | | | | If USE_VBE_RM is 0, vesa_realmode_bootup_init() is not available so the test should be #if instead of #ifdef.

* pc386/.../bsp.h: Do not include crt.hJoel Sherrill2014-09-161-6/+0
| | | | | | | crt.h defines such lovely constants as "RED" and "GREEN" which have a nasty habit of conflicting with non-BSP code. There is no reason to include this private .h from bsp.h and pollute the namespace for applications.
* Use correct prototype of benchmark_timer_read()Joel Sherrill2014-09-161-3/+3
| | | | | | | | | | | | | | This change starts with removing the effectively empty file timerdrv.h. The prototypes for benchmark_timer_XXX() were in btimer.h which was not universally used. Thus every use of timerdrv.h had to be changed to btimer.h. Then the prototypes for benchmark_timer_read() had to be adjusted to return benchmark_timer_t rather than int or uint32_t. I took this opportunity to also correct the file headers to separate the copyright from the file description comments which is needed to ensure the copyright isn't propagated into Doxygen output.
* Regenerate all preinstall.am files.Chris Johns2014-08-291-5/+5
| | | | | With this patch the preinstall.am files are in a set order and not dependent on now perl implements a hash.
* bsps: Fix TLS support in linker command filesSebastian Huber2014-04-221-1/+3
| | | | | The TLS section symbols had wrong values in case of an empty TLS data section and a nonempty TLS BSS section.
* score: Add clustered/partitioned schedulingSebastian Huber2014-04-151-1/+7
| | | | | | | | | | | | | | | Clustered/partitioned scheduling helps to control the worst-case latencies in the system. The goal is to reduce the amount of shared state in the system and thus prevention of lock contention. Modern multi-processor systems tend to have several layers of data and instruction caches. With clustered/partitioned scheduling it is possible to honour the cache topology of a system and thus avoid expensive cache synchronization traffic. We have clustered scheduling in case the set of processors of a system is partitioned into non-empty pairwise-disjoint subsets. These subsets are called clusters. Clusters with a cardinality of one are partitions. Each cluster is owned by exactly one scheduler instance.
* score: SMP initialization changesSebastian Huber2014-04-141-5/+13
| | | | | | | | | | | | | | | | | Add and use _CPU_SMP_Start_processor(). Add and use _CPU_SMP_Finalize_initialization(). This makes most _CPU_SMP_Initialize() functions a bit simpler since we can calculate the minimum value of the count of processors requested by the application configuration and the count of physically or virtually available processors in the high-level code. The CPU port has now the ability to signal a processor start failure. With the support for clustered/partitioned scheduling the presence of particular processors can be configured to be optional or mandatory. There will be a fatal error only in case mandatory processors are not present. The CPU port may use a timeout to monitor the start of a processor.
* pc386/include/bsp.h: Remove rtems_bsp_delay()Joel Sherrill2014-03-211-16/+0

* score: Rename rtems_smp_process_interrupt()Sebastian Huber2014-02-191-5/+3
| | | | | | Rename rtems_smp_process_interrupt() into _SMP_Inter_processor_interrupt_handler(). Delete unused header file <rtems/bspsmp.h>.
* score: Rename rtems_smp_secondary_cpu_initialize()Sebastian Huber2014-02-191-1/+2
| | | | | | Rename rtems_smp_secondary_cpu_initialize() into _SMP_Start_multitasking_on_secondary_processor(). Move declaration to <rtems/score/smpimpl.h>.
* score: Delete bsp_smp_broadcast_interrupt()Sebastian Huber2014-02-191-6/+0
| | | | | | Since the per-CPU SMP lock must be acquired and released to send the message a single interrupt broadcast operations offers no benefits. If synchronization is required, then a SMP barrier must be used anyway.
* score: Rename bsp_smp_initialize()Sebastian Huber2014-02-191-1/+1
| | | | | Rename bsp_smp_initialize() into _CPU_SMP_Initialize() since every CPU port must supply this function.

| | | | | | | pc386 set CLOCK_DRIVER_ISRS_PER_TICK to a string rather than a numeric value. Add CLOCK_DRIVER_ISRS_PER_TICK_VALUE and other clean up on the clock driver.

Delete bsp_smp_interrupt_cpu(). Change type of current processor index from int to uint32_t to match _SMP_Processor_count type. This commit was completely reverted. commit e94aa61b6820e34732840139dbe3f2016c6f1e24 Author: Till Straumann <strauman@slac.stanford.edu> Date: Fri Aug 5 00:15:50 2011 +0000 2011-08-04 Till Straumann <strauman@slac.stanford.edu> * shared/irq/irq_asm.S: BUGFIX (introduced by SMP changes which moved code around, apparently): *must* store i8259 mask to frame *before* switching to IRQ stack. The code retrieves the mask after switching back to original stack. Also, the IRQ stack has no reserved space for the mask; storing it there could overwrite memory! This commit was completely reverted. commit 01f2692e338d592f363b2e27b2f62d8182d1124e Author: Jennifer Averett <Jennifer.Averett@OARcorp.com> Date: Mon Aug 1 13:41:50 2011 +0000 2011-08-01 Jennifer Averett <Jennifer.Averett@OARcorp.com> PR 1802 * shared/irq/irq_asm.S, shared/irq/irq_init.c, shared/smp/smp-imps.c, shared/smp/smp-imps.h: Add SMP support for i386. * shared/smp/getcpuid.c: New file. The parts modifying the code of _ISR_Handler were reverted. commit 66729db3115e865fa45bc4e9ab81d8266894151c Author: Joel Sherrill <joel.sherrill@OARcorp.com> Date: Wed Mar 16 20:05:17 2011 +0000 2011-03-16 Jennifer Averett <jennifer.averett@OARcorp.com> PR 1729/cpukit * shared/irq/irq_asm.S: Add next step in SMP support. 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. This commit was completely reverted.
