* libblock: Fix read-ahead task wake-upSebastian Huber2012-07-091-5/+10
| | | | | | | | | In case the read-ahead task is not configured we must not send a wake-up event. This would send the wake-up event to the executing task. We must send the wake-up event only in case the request list changes from empty to non-empty. Since otherwise we may send a false transfer event.
* libblock: Move read-ahead trigger checkSebastian Huber2012-07-031-1/+2
| | | | | | In case the read-ahead task has a higher priority than the reading task, this ensures that the read-ahead request is issued after the read miss is serviced.
* libblock: Fix read-ahead trigger and next updateSebastian Huber2012-07-021-1/+1
| | | | | The previous version was sub-optimal for read-ahead transfer counts of one.

* libblock: Add read-ahead taskSebastian Huber2012-06-041-121/+226
| | | | | | | | | | | 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.

* libblock: Simplify disk managementSebastian Huber2012-05-311-11/+16
| | | | | Add block_count and media_blocks_per_block to rtems_disk_device. Add and use rtems_disk_init_phys() and rtems_disk_init_log().

* libblock: Add task stack size bdbuf configurationSebastian Huber2012-05-311-35/+41
| | | | | | The task stack size for the swap-out and worker tasks is now configurable. The bdbuf task resources are now included in the work space size estimate.

* libblock: Add rtems_bdbuf_set_block_size()Sebastian Huber2012-04-121-51/+73
| | | | | | | | The new function rtems_bdbuf_set_block_size() must be used to set the block size of a disk device. It will check if the block size is valid and set the new fields block_to_media_block_shift and bds_per_group of the rtems_disk_device structure. This helps to avoid complex arithmetic operations in the block device buffer get and read path.
* libblock: Change error status to fatal errorSebastian Huber2012-04-121-11/+7
| | | | | Calling the bdbuf API functions in the not configured state is now a fatal error.
* libblock: Use unprotected chain operationsSebastian Huber2012-04-121-4/+4
| | | | The transfer chain is accessed by at most one thread at a time.
* libblock: Use unprotected chain operationsSebastian Huber2012-04-121-17/+17
| | | | The chains are protected by the bdbuf cache lock.
* libblock: Change bdbuf APISebastian Huber2012-03-131-159/+78
| | | | | | | | | | | | | | | | | | | | The functions o rtems_bdbuf_get(), o rtems_bdbuf_read(), o rtems_bdbuf_syncdev(), and o rtems_bdbuf_purge_dev(), use now the disk device instead of the device identifier. This makes bdbuf independent of rtems_disk_obtain() and rtems_disk_release(). It is the responsiblity of the file system to obtain the disk device. This also reduces the overhead to get a buffer. The key for the AVL tree uses now the disk device instead of the device identifier. The pointer is interpreted as an unsigned integer. This reduces the memory overhead and makes the comparison operation a bit faster. Removed function rtems_bdbuf_purge_major(). This function was too destructive and could have unpredictable side effects.
* libblock: Remove superfluous volatile qualifierSebastian Huber2012-03-131-6/+6
| | | | All these variables are protected by the bdbuf cache mutex.
