* score: Fix performance issue for 64-bit timestampsSebastian Huber2012-06-145-62/+22
| | | | | | | | | | | | | The 64-bit timestamps were introduced to simplify the timestamp calculations. This works well since nearly all operations are additions. The previous _TOD_Tickle_ticks() implementation had a serious performance regression in case of 64-bit timestamps due to the usage of two 64-bit divisions which are quite expensive on some architectures. A new field seconds_trigger in TOD_Control is introduced to trigger the _Watchdog_Tickle_seconds() in _TOD_Tickle_ticks(). This avoids the 64-bit divisions completely and only 32-bit additions are used.
* score: New structure TOD_ControlSebastian Huber2012-06-1413-40/+43
| | | | | Group the global TOD variables (_TOD_Now, _TOD_Uptime, and _TOD_Is_set) in a structure to reduce address loads in _TOD_Tickle_ticks().
* sapi: Add nanoseconds_per_tick to configurationSebastian Huber2012-06-143-2/+16
| | | | | | Add nanoseconds_per_tick to rtems_configuration_table. This value will be derived from the microseconds_per_tick value. This avoids some calculations at run-time.

* bsps: Replace NIRVANA regionSebastian Huber2012-06-1251-71/+68
| | | | | Replace the "NIRVANA" region with the more verbose "UNEXPECTED_SECTIONS" region. Move the region definition into the "linkcmds.base" files.

| | | | | | | | | | | | | | | | | | Port + v850 does not have appear to have any optimized bit scan instructions + v850 does have single instructions for wap u16 and u32 + Code path optimization preferences set + Add BSP variants for each GCC CPU model flag and a README - v850e1 variant does not work (fails during BSP initialization) BSP for GDB v850 Simulator + linkcmds matches defaults in GDB simulator with RTEMS mods + crt1.c added from v850 newlib port for __main() + BSP exits cleanly + printk and console I/O work + uses clock tick from IDLE task + Tests not requiring real clock ISR work Documentation + CPU Supplment chapter for v850 added

* librpc: PR2066: Fix for short enumsSebastian Huber2012-06-067-15/+23
| | | | | | | | | | The XDR library has a problem on architectures with short enums like the default ARM EABI. Short enums means that the size of the enum type is variable and the smallest integer type to hold all enum values will be selected. For many enums this is char. The XDR library uses int32_t for enum_t. There are several evil casts from an enum type to enum_t which leads to invalid memory accesses on short enum architectures. A workaround is to add appropriate dummy enum values.

* dosfs: Fix for no space left on device conditionSebastian Huber2012-06-041-3/+5
| | | | | | The file size was wrong in the no space left on device condition. This resulted in turn in a read of an invalid block which lead to an EIO error status.
* libblock: Add read-ahead taskSebastian Huber2012-06-0411-130/+568
| | | | | | | | | | | Read-ahead requests were previously executed in the context of the reading task. This blocks the reading task until the complete read with read-ahead transfer is finished. A read-ahead task is introduced to off-load the read-ahead transfer. This allows the reading task to work with the requested block more quickly. The read-ahead is triggered after two misses of ascending consecutive blocks or a read hit of a block read by the most-recent read-ahead transfer. The read-ahead feature is configurable and can be disabled.

* bsp/qoriq: New BSP optionSebastian Huber2012-06-042-0/+6
| | | | New BSP option BSP_USE_DATA_CACHE_BLOCK_TOUCH.
* powerpc: Simplify context switchSebastian Huber2012-06-048-514/+285
| | | | | | | | | | | | | | | | | | | PowerPC cores with the SPE (Signal Processing Extension) have 64-bit general-purpose registers. The SPE context switch code has been merged with the standard context switch code. The context switch may use cache operations to increase the performance. It will be ensured that the context is 32-byte aligned (PPC_DEFAULT_CACHE_LINE_SIZE). This increases the overall memory size of the context area in the thread control block slightly. The general-purpose registers GPR2 and GPR13 are no longer part of the context. The BSP must initialize these registers during startup (usually initialized by the __eabi() function). The new BSP option BSP_USE_DATA_CACHE_BLOCK_TOUCH can be used to enable the dcbt instruction in the context switch. The new BSP option BSP_USE_SYNC_IN_CONTEXT_SWITCH can be used to enable sync and isync instructions in the context switch. This should be not necessary in most cases.
