* PR 1548: ERC32 console stops working when UART error flags are setGerardo Puga2014-01-091-0/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: The console works fine when only transmitting data from the ERC32, but stops working after a while when receiving data. "Stops working" means, bytes are neither sent nor received from the UART, but the rest of the system keeps functioning (task are executing, the operative system is responsive, etc). Context: - When an RX error occurs, the ERC32 UARTS stop generating RX/TX interrupts until the corresponding error flag in the UART_STATUS are cleared. - The console.c code currently cleans the error flags from the console_isr_x subroutines, but those are NOT called when an RX error occurs. Thus the error flag is never cleaned and then the UARTs stop generating interrupts indefinitely. - The ERC32 UARTs generate a different interrupt when an RX error occurs. Fixed by: - Adding a third interrupt service routine console_isr_error to handle the UART_ERROR trap. This isr cleans the error flags of the channels. - Cleaning the error flags manually just after having initialized the interrupt vectors. This is because if the error flag was already set by the time the interrupt vectors are configured, the interrupts might never be called.
* PR1960: ERC32_Is_interrupt_masked for ERC32 in erc32.hHelder Silva2013-12-111-1/+1
| | | | | | | | | | The function-like macro ERC32_Is_interrupt_masked defined as: (ERC32_MEC.Interrupt_Masked & (1 << (_source))) The ERC32_MEC is of type ERC32_Register_Map structure and Interrupt_Masked does not exist in structure, instead Interrupt_Mask exists. Update the macro accordingly.

* smp: Simplify SMP initialization sequenceSebastian Huber2013-05-291-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Delete bsp_smp_wait_for(). Other parts of the system work without timeout, e.g. the spinlocks. Using a timeout here does not make the system more robust. Delete bsp_smp_cpu_state and replace it with Per_CPU_State. The Per_CPU_State follows the Score naming conventions. Add _Per_CPU_Change_state() and _Per_CPU_Wait_for_state() functions to change and observe states. Use Per_CPU_State in Per_CPU_Control instead of the anonymous integer. Add _CPU_Processor_event_broadcast() and _CPU_Processor_event_receive() functions provided by the CPU port. Use these functions in _Per_CPU_Change_state() and _Per_CPU_Wait_for_state(). Add prototype for _SMP_Send_message(). Delete RTEMS_BSP_SMP_FIRST_TASK message. The first context switch is now performed in rtems_smp_secondary_cpu_initialize(). Issuing the first context switch in the context of the inter-processor interrupt is not possible on systems with a modern interrupt controller. Such an interrupt controler usually requires a handshake protocol with interrupt acknowledge and end of interrupt signals. A direct context switch in an interrupt handler circumvents the interrupt processing epilogue and may leave the system in an inconsistent state. Release lock in rtems_smp_process_interrupt() even if no message was delivered. This prevents deadlock of the system. Simplify and format _SMP_Send_message(), _SMP_Request_other_cores_to_perform_first_context_switch(), _SMP_Request_other_cores_to_dispatch() and _SMP_Request_other_cores_to_shutdown().

| | | | | | | | | This commit deletes all RTEMS ChangeLog files. These files have been abandoned since converting to git version control. The historical data may be recovered by checking out any commit before this one. Most of the contents of these ChangeLog files can also be found in the git log. Two external ChangeLog files, ChangeLog.slac and ChangeLog.zlib, remain.

| | | | | | | | | | | | | | | | | | | | | Add CPU port type CPU_Exception_frame and function _CPU_Exception_frame_print(). The CPU ports of avr, bfin, h8300, lm32, m32c, m32r, m68k, nios2, sh, sparc64, and v850 use an empty default implementation of _CPU_Exception_frame_print(). Add rtems_exception_frame and rtems_exception_frame_print(). Add RTEMS_FATAL_SOURCE_EXCEPTION for CPU exceptions. Use rtems_fatal() with source RTEMS_FATAL_SOURCE_EXCEPTION in CPU ports of i386, powerpc, and sparc for unexpected exceptions. Add third parameter to RTEMS_BSP_CLEANUP_OPTIONS() which controls the BSP_PRINT_EXCEPTION_CONTEXT define used in the default bsp_fatal_extension(). Add test sptests/spfatal26.

* bsps/sparc: Add BSP_INITIAL_EXTENSION to <bsp.h>Sebastian Huber2012-11-132-0/+3
| | | | The bsp_fatal_extension() will call BSP_fatal_return().
* score: Work area initialization API changeSebastian Huber2012-10-251-2/+2
| | | | | | | | | | | | 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.

* SPARC BSPs: implemented shared-irq using libbsp/shared layerDaniel Hellstrom2012-04-066-2/+163
| | | | | | | | | | | | | | | 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
* SPARC: bsp_early_malloc() routine for startup memory allocationDaniel Hellstrom2012-03-292-3/+8
| | | | | | | | | | | | If bsp_early_malloc() is called early during boot room will be allocated after BSS END. If the function is called after boot is will call malloc() instead. The returned memory is not freeable and always 8-byte aligned. If the bsp_early_malloc() isn't called the function is not dragged in and the workspace will be unmodified in size.

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.
