* sparc: Save/restore only non-volatile contextSebastian Huber2014-02-121-15/+4
| | | | | | | | | | The _CPU_Context_switch() is a normal function call. The following registers are volatile (the caller must assume that the register contents are destroyed by the callee) according to "SYSTEM V APPLICATION BINARY INTERFACE - SPARC Processor Supplement", Third Edition: g1, o0, o1, o2, o3, o4, o5. Drop these registers from the context. Ensure that offset defines match the structure offsets.
* bsps/sparc: Fix ambapp_find_by_idx()Sebastian Huber2014-02-111-1/+1
| | | | The expression "*pi++" post-increments the pointer (not the value).
* score: _CPU_Context_switch_to_first_task_smp()Sebastian Huber2014-02-051-28/+0
| | | | | Delete _CPU_Context_switch_to_first_task_smp() and use _CPU_Context_restore() instead.
* bsp/leon3: Fix SMP initializationSebastian Huber2014-02-051-24/+23
| | | | | | | Avoid usage of the same stack area by multiple secondary processors at the same time. Avoid magic delay loops.

* sparc/shared/irq_asm.S: Get pointer to self per-CPU controlDaniel Hellstrom2013-11-301-0/+1
| | | | | | | | _CPU_Context_switch_to_first_task_smp() branches to done_flushing which requires o3 to be initalized with "self per-CPU control", this adds initialization of o3. This problem only affects SMP, see commit f8ad6c6f7f8b591e were usage of o3 was intruduced.

* SPARC BSPs: disable interrupts as early as possibleDaniel Hellstrom2013-10-311-2/+2
| | | | | | | | | There is no point having interrupts enabled before reaching boot_card() that disables interrupt. We better have it off all the time. It is required to turn off interrupt on secondary CPUs in an SMP system.
* LEON3_MP ISR: shared-IRQ setup overwrite SMP/MP ISR trap handlerDaniel Hellstrom2013-10-311-0/+5
| | | | | | Basically the shared-irq handler overwrite the SMP/MP traphandler previously initialized with set_vector(). That caused IPIs to enter BSP spurious handler.
* sparc all BSPs: Use function and data sectionsJoel Sherrill2013-10-241-8/+9
| | | | This reduces the size of the RTEMS tests on average about 45%.

* sparc: Make _CPU_ISR_Dispatch_disable per-CPUSebastian Huber2013-08-091-22/+20
| | | | This variable must be available for each processor in the system.
* sparc: Move _CPU_Context_switch(), etc.Sebastian Huber2013-08-091-0/+224
| | | | | | Move the _CPU_Context_switch(), _CPU_Context_restore() and _CPU_Context_switch_to_first_task_smp() code since the method to obtain the processor index is BSP specific.
* bsps/sparc: SMP and per-CPU thread dispatch disableSebastian Huber2013-08-091-10/+25

The commit restores the _ISR_Handler code to the original version in "cpukit/score/sparc/cpu_asm.S" in commit 6d42b4c60a4ac686489b793d5df2047c735c7c94.

I would need a long test with interrupts to verify the interrupt handler better, however I can not see that these patches hurt. Please see comment per hunk below, One should go through the file to indent delay-slots correctly, I have fixed some in the patch areas. An extra space is added in front of delay slots to indicate a delay slot. This commit was completely reverted. commit 0bd3f7e5d12fdbfb5bf4aa4a4169c67bfd92c988 Author: Jennifer Averett <Jennifer.Averett@OARcorp.com> Date: Thu Jul 28 17:33:07 2011 +0000 2011-07-28 Jennifer Averett <Jennifer.Averett@OARcorp.com> PR 1801 * shared/irq_asm.S: Modifications to synch the sparc with the smp working tree.

* score: Work area initialization API changeSebastian Huber2012-10-252-20/+11
| | | | | | | | | | | | The work areas (RTEMS work space and C program heap) will be initialized now in a separate step and are no longer part of rtems_initialize_data_structures(). Initialization is performed with tables of Heap_Area entries. This allows usage of scattered memory areas present on various small scale micro-controllers. The sbrk() support API changes also. The bsp_sbrk_init() must now deal with a minimum size for the first memory chunk to take the configured work space size into account.

* LEON: moved register definitions into grlib header fileDaniel Hellstrom2012-05-167-57/+110
| | | | | | | | | | | | Some register layout definitions for LEON3 reside in ambapp.h which does not really has anything to do with device registers. The register structures has been incorrectly named LEON3_*, the cores are not only used on LEON3 but on LEON4 and perhaps on LEON5 when that day comes. Some structures has been renamed according to the GRLIB core name instead, which CPU that actually use it is not relevant. Drivers has been updated with the new names.

* LEON: updated drivers to use new AMBAPP LayerDaniel Hellstrom2012-04-1729-225/+222
| | | | | | | The drivers are updated to use the new AMBA layer, however the backwards-compatibility interface (ambapp_old) is used. Signed-off-by: Daniel Hellstrom <daniel@gaisler.com>
* LEON: updated AMBA PnP APIDaniel Hellstrom2012-04-1712-610/+1758
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The old layer had some limitations/problems for multiple AHB buses since the data structure containing all AMBA devices were allocated before scanning. The new layer create devices as they are found and memory is allocated using malloc() or bsp_early_malloc() during booting. The old 8 functions for finding a specific AHB-Slave or APB-Slave device has been replaced with one function, ambapp_for_each(), which iterates over all devices matching the specified search options and calls a user provided function. The new way lowers the footprint and makes searching more flexible. The frequency information is now supported, if the frequency of one device is reported by the user. More AHB-to-AHB bridges are supported. The API has been split into several parts in order to lower the footprint. The API also introduces the AMBAPP CORE concept, where one ambapp_core can be created from one AHB Master, AHB Slave and one APB Slave, at least one device is required for creating a core.

* SPARC BSPs: implemented shared-irq using libbsp/shared layerDaniel Hellstrom2012-04-062-0/+85
| | | | | | | | | | | | | | | The implementation use IRQ number instead of vector number since some IRQs does not have a unique vector, for example the extended interrupts all enter the same trap vector entry. Added support for the LEON3 extended interrupt controller when using the shared IRQ layer. ERC32 patches untested. Signed-off-by: Daniel Hellstrom <daniel@gaisler.com> Regenerate
