2018-01-25Remove make preinstallChris Johns1-511/+0
A speciality of the RTEMS build system was the make preinstall step. It copied header files from arbitrary locations into the build tree. The header files were included via the -Bsome/build/tree/path GCC command line option. This has at least seven problems: * The make preinstall step itself needs time and disk space. * Errors in header files show up in the build tree copy. This makes it hard for editors to open the right file to fix the error. * There is no clear relationship between source and build tree header files. This makes an audit of the build process difficult. * The visibility of all header files in the build tree makes it difficult to enforce API barriers. For example it is discouraged to use BSP-specifics in the cpukit. * An introduction of a new build system is difficult. * Include paths specified by the -B option are system headers. This may suppress warnings. * The parallel build had sporadic failures on some hosts. This patch removes the make preinstall step. All installed header files are moved to dedicated include directories in the source tree. Let @RTEMS_CPU@ be the target architecture, e.g. arm, powerpc, sparc, etc. Let @RTEMS_BSP_FAMILIY@ be a BSP family base directory, e.g. erc32, imx, qoriq, etc. The new cpukit include directories are: * cpukit/include * cpukit/score/cpu/@RTEMS_CPU@/include * cpukit/libnetworking The new BSP include directories are: * bsps/include * bsps/@RTEMS_CPU@/include * bsps/@RTEMS_CPU@/@RTEMS_BSP_FAMILIY@/include There are build tree include directories for generated files. The include directory order favours the most general header file, e.g. it is not possible to override general header files via the include path order. The "bootstrap -p" option was removed. The new "bootstrap -H" option should be used to regenerate the "headers.am" files. Update #3254.
2016-04-07libblock: Drop superfluous <stdlib.h> includeSebastian Huber1-1/+0
Drop superfluous <stdlib.h> include from <rtems/diskdevs.h> since this leads to conflicts with the latest Newlib in case this header file is used in the FreeBSD kernel space, e.g. for USB mass storage support.

This is the result of a sed script which converts all uses of @{ into a consistent form.

2012-06-04libblock: Add read-ahead taskSebastian Huber1-0/+37
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.
2012-05-31libblock: Simplify disk managementSebastian Huber1-11/+43
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 Sherrill1-2/+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.
2012-04-12libblock: Add rtems_bdbuf_set_block_size()Sebastian Huber1-2/+22
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.
2012-03-13libblock: New support functionsSebastian Huber1-0/+21
Add o rtems_disk_get_block_size(), o rtems_disk_get_block_begin(), and o rtems_disk_get_block_count().

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.

* sapi/include/confdefs.h, libblock/include/rtems/bdbuf.h: Changed type of rtems_bdbuf_pool_configuration_size to size_t. * libblock/include/rtems/bdbuf.h, libblock/include/rtems/blkdev.h, libblock/include/rtems/diskdevs.h, libblock/src/bdbuf.c, libblock/src/blkdev.c, libblock/src/diskdevs.c: Buffer pool allocation is now cache aligned. The cache functions are currently not available on all platforms so the cache line size is fixed to 32 bytes for now. Changed various integer types which refer to block sizes, numbers and indexes. Fixed logical block indexes in buffer get and read function. It is now possible to delete logical disks. Modified documentation
