* libblock: Add read-ahead taskSebastian Huber2012-06-042-7/+56
| | | | | | | | | | | 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 Huber2012-05-312-17/+48
| | | | | 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: Remove const qualifier from bdbuf APISebastian Huber2012-05-313-6/+6
| | | | This allows addtion of per disk statistics for example.
* libblock: Add task stack size bdbuf configurationSebastian Huber2012-05-311-3/+10
| | | | | | 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.
* Remove All CVS Id Strings Possible Using a ScriptJoel Sherrill2012-05-117-14/+0
| | | | | | | | | | | | Script does what is expected and tries to do it as smartly as possible. + remove occurrences of two blank comment lines next to each other after Id string line removed. + remove entire comment blocks which only exited to contain CVS Ids + If the processing left a blank line at the top of a file, it was removed.
* libblock: Add RTEMS_BLKIO_PURGEDEVSebastian Huber2012-05-111-0/+6

* libblock: Add rtems_bdbuf_set_block_size()Sebastian Huber2012-04-122-4/+43
| | | | | | | | 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 Huber2012-04-121-13/+40
| | | | | Calling the bdbuf API functions in the not configured state is now a fatal error.
* PR2040: libblock: Flash disk documentationSebastian Huber2012-03-141-28/+119

* libblock: Add generic IMFS block device nodesSebastian Huber2012-03-131-0/+50
| | | | | | | | New functions o rtems_blkdev_create(), and o rtems_blkdev_create_partition(). New test libtests/block11.
* libblock: New support functionsSebastian Huber2012-03-131-0/+21
| | | | | | | Add o rtems_disk_get_block_size(), o rtems_disk_get_block_begin(), and o rtems_disk_get_block_count().
* libblock: Change bdbuf APISebastian Huber2012-03-132-28/+27
| | | | | | | | | | | | | | | | | | | | 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.
