2020-04-16Canonicalize config.h includeSebastian Huber
Use the following variant which was already used by most source files: #ifdef HAVE_CONFIG_H #include "config.h" #endif
2018-08-07libblock: Add RTEMS_DEPRECATEDSebastian Huber
Close #3358.
2018-02-02libblock: Use self-contained mutex for disk lockSebastian Huber
Update #2843.
2016-06-06libblock: Use proper semaphore attr for mutexSebastian Huber
Close #1452.
2015-03-05libblock: Fix warningSebastian Huber
2014-03-14score: Add SMP lock profiling supportSebastian Huber
2014-03-11score: Add local context to SMP lock APISebastian Huber
Add a local context structure to the SMP lock API for acquire and release pairs. This context can be used to store the ISR level and profiling information. It may be later used to enable more sophisticated lock algorithms, e.g. MCS locks. There is only one lock that cannot be used with a local context. This is the per-CPU lock since here we would have to transfer the local context through a context switch which is very complicated.
2013-08-14libblock: Add missing initializerSebastian Huber
2013-08-14libblock: Add SMP supportSebastian Huber
2012-05-31libblock: Simplify disk managementSebastian Huber
Add block_count and media_blocks_per_block to rtems_disk_device. Add and use rtems_disk_init_phys() and rtems_disk_init_log().
2012-05-11Remove All CVS Id Strings Possible Using a ScriptJoel Sherrill
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.
2012-04-12libblock: Add rtems_bdbuf_set_block_size()Sebastian Huber
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.

rtems_disk_device. * libblock/include/rtems/blkdev.h: New request code RTEMS_BLKIO_DELETED. * libblock/src/diskdevs.c: Major rewrite. Changed the way disks are deleted. Disks will be now deleted if they are not in use or upon last release. The IO control handler will be invoked if a physical disk is deleted with the RTEMS_BLKIO_DELETED request code. Logical disks increase now the usage count of the associated physical disk. * libblock/include/rtems/ramdisk.h: Documentation. * libblock/src/ramdisk-driver.c: Compile trace support conditionally.
