* score: PR2179: Fix initially locked PCP mutexesSebastian Huber2014-05-233-2/+40
| | | | | Elevate the priority of the creating task to the ceiling priority in case a semaphore is created as initially locked.
* posix: fix race condition between pthread_create and capture engineTill Strauman2014-04-111-0/+5
| | | | | | | Fix PR 2068: Reproducable crashes occur when using pthreads and the capture engine at the same time. 'pthread_create()' is the culprit. It creates a SCORE thread and then calls Thread_Start( ) without disabling thread-dispatching.
* rtems_cache_invalidate_multiple_instruction_linesAleksandr Platonov2014-01-141-1/+1
| | | | | | | | According with comment in rtems_cache_invalidate_multiple_instruction_lines(), final_address indicates the last address which needs to be invalidated. But if in while loop we got final_address == i_addr condition then loop breaks and final_address will not be invalidated.

* SPI SD-Card: setup valid CRC-7 for STOP_TRANSMISSION command.Pavel Pisa2013-10-081-0/+5
| | | | | | | | | | | | STOP_TRANSMISSION command is used to finish READ_MULTIPLE_BLOCK command and its format is regular command format. It requires valid CRC-7 to have effect at least on same cards types else it is ignored and attempt to issue next READ or WRITE commands results in illegal command condition (0x04) preceded by strange (0x3f) for tested card.

| | | | | | The _Thread_queue_Process_timeout() operation had several race conditions in the event of nested interrupts. Protect the critical sections via disabled interrupts.

* bsp/csb336: Memory map update to support i.MX1 based PiMX1 as well.Pavel Pisa2013-08-191-3/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | CSB336 i.MX1/i.MXS memory map organization - SDRAM starts at address 0x08000000 but 2 MB are reserved for boot-block/loader (or other use) before RTEMS image origin/load address (that is kept from previous setup) - Caching of 30 MB of SDRAM used for RTEMS (start at 0x08200000) is changed to writeback mode which provides higher throughput. - The first 1 MB of RTEMS dedicated SDRAM is remapped to address 0 to provide area for ARM CPU exceptions table. - Internal registers and rest of the Flash (above 1 MB) are mapped one to one. Registers region is extended to 2 MB to cover eSRAM found on i.MX1 chip variant. - The first two megabytes of SDRAM unused by RTEMS are mapped with attributes to allow specific purposes. - the first MB (at address 0x08000000) is nocached to allow directly set some values read by booot-block after warm reset - the second MB (at address 0x08100000) is set for write-through caching. That allows to use memory for LCD frame-buffer without need to flush cache after each redraw. Signed-off-by: Pavel Pisa <pi@baree.pikron.com>

* bsp/csb336: mc9328mxl correct AITC access in bsp_interrupt_dispatch.Pavel Pisa2013-08-191-1/+2
| | | | | | | | | | | The original version is missing void and result is that (*x >> 16) is optimized to ldh rX,[rY]. But it is not allowed/supported to access bus/address range used by AITC by other than 32 bit wide accesses and 16-bit access results in the data abort exception. The corrected version works on real hardware and is even more readable. Signed-off-by: Pavel Pisa <ppisa@pikron.com>

| | | | | | | Commit 4b45c1393ce4ee3e1c2762ef3145d2bd6b5b38da marked a test in _Event_Timeout() as debug only. This test is required also in non-debug configurations since otherwise state corruption can happen. A revised test sptests/spintrcritical10 checks the relevant sequences.
* score: Critical fix for timer serverSebastian Huber2012-12-061-7/+0
| | | | | | | | Under certain conditions it is possible that a call to _Watchdog_Adjust_to_chain() happens with a unit parameter value of zero (for example sptests/spintrcritical17). Remove superfluous checks that prevent an adjust to a chain of a watchdog chain which first element has a delta zero value.

* libblock: PR2040: Add starvation thresholdSebastian Huber2012-04-161-1/+15

* PR2040: libblock: Avoid erased blocks starvationSebastian Huber2012-03-141-115/+185
| | | | | | | | | | | | The compaction process needs erased blocks. It is only possible to erase an entire segment. Thus in order to make a progress we always need enough erased blocks to empty a used or available segment which can be erased in turn. A (possibly the worst case) lower bound of erased blocks is the block count of the largest segment. The number of unavailable blocks specified by the configuration will be used to determine the erase blocks starvation situation. The number of unavailable blocks must be greater than or equal to the number of blocks in the largest segment.

* PR2039: Fix NULL pointer accessSebastian Huber2012-03-141-2/+2
| | | | | | | In case rtems_bdbuf_read() returns an error status, the block device buffer pointer will be set to NULL. In RFS the chain node of the block device buffer will be used for RFS purposes. We must not do this after an erroneous read.

* LEON3: CPU index intialization moved to bspstart.cJoel Sherrill2012-02-022-18/+18
| | | | | | | | | | | | | | | | | 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.
