* pci.h cleanup - Consolidate common defines to cpukit pci.hJoel Sherrill2012-05-161-4/+8
| | | | | | | | | | | | | + libbsp/sparc/shared/include/pci.h was largely a copy of an older version of the cpukit pci.h. Removed much of the contents and included <rtems/pci.h>. + sparc/*/pci*.c - Move to <rtems/pci.h> required updating to use uint32_t for dword accesses. + Rename PCI_MULTI_FUNCTION to PCI_HEADER_TYPE_MULTI_FUNCTION + Define PCI_HEADER_TYPE_MULTI_FUNCTION in cpukit pci.h and remove PCI_MULTI_FUNCTION definitions in C files. + Move PCI_INVALID_VENDORDEVICEID definitions from various C files to cpukit pci.h
* mvme5500 and cpukit pci.h - Eliminate mvme5500 specific pci.hJoel Sherrill2012-05-161-2/+12
| | | | | | | | All constants that should have been in cpukit pci.h were moved there. One naming style was corrected. This impacted if_wm.c. All other contents were the same as powerpc/shared/pci.h so BSP specific pci.h could be eliminated.
* nfsclient: Fix symbolic link evaluationSebastian Huber2012-05-161-66/+97

* libcsupport: Adjust malloc_walk() prototypeSebastian Huber2012-05-163-3/+4
| | | | | | | | The header file <rtems/malloc.h> provides now also the malloc_walk() prototype. The malloc_walk() prototype reflects now the _Protected_heap_Walk() API. The return status helps to print only in case of an error.
* Filesystem: Add missing include file <stdint.h>Sebastian Huber2012-05-151-0/+1

* Filesystem: Change pathconf_limits_and_optionsSebastian Huber2012-05-156-11/+7
| | | | | | The pathconf_limits_and_options field of rtems_filesystem_mount_table_entry_t is now a const pointer to reduce the read-write memory demands of file system instances.
* Filesystem: Move operations to mount table entrySebastian Huber2012-05-1537-64/+76
| | | | | | | | | | | The scope of the file system operations is the file system instance. The scope of the file system node handlers is the file location. The benefit of moving the operations to the mount table entry is a size reduction of the file location (rtems_filesystem_location_info_t). The code size is slightly increased due to additional load instructions. Restructure rtems_filesystem_mount_table_entry_t to improve cache efficiency.
* Filesystem: Add const qualifier to lock/unlockSebastian Huber2012-05-157-15/+19
|
* Filesystem: PR1255: Move offset update to handlersSebastian Huber2012-05-1511-20/+39
| | | | | | | It is now the responsibility of the read() and write() handler to update the offset field of the IO descriptor (rtems_libio_t). This change makes it possible to protect the IO descriptor from concurrent access by per file locks.
* Filesystem: Add shared device IO supportSebastian Huber2012-05-1514-289/+255
| | | | | The device IO file system support in IMFS, devFS, and RFS uses now a shared implementation.

* PR2065: RBTree: Insert function (protected) does not enable interruptsGedare Bloom2012-05-131-2/+4
| | | | | Save the return value from the unprotected version and return it after enabling interrupts to their previous level.
* Remove CVS Id Strings (manual edits after script)Joel Sherrill2012-05-1137-79/+3
| | | | | | These modifications were required by hand after running the script. In some cases, the file names did not match patterns. In others, the format of the file did not match any common patterns.
* cpukit/aclocal - Fix one mistake by scriptJoel Sherrill2012-05-111-0/+1

* Remove All CVS Id Strings Possible Using a ScriptJoel Sherrill2012-05-111906-3912/+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.
* dosfs: Remove fat_file_datasync()Sebastian Huber2012-05-118-179/+73
| | | | | | | | | | | | | | | The fat_file_datasync() read every cluster of the file into the cache and then synchronized it step-by-step. For unmodified buffers this is a non-operation. For modified buffers this will wake-up the swapout task which performs then a single buffer write operation. This is usually quite inefficient. Firstly we do single buffer writes, secondly we may perform a lot of unnecessary read operations (for huge files this is really bad), and thirdly this leads likely to cache evictions. The synchronization procedure is replaced by a simple rtems_bdbuf_sync_dev(). This has the side-effect that also buffers not related to the file are synchronized, but since the modified list is normally short this should be acceptable.
* libblock: Add RTEMS_BLKIO_PURGEDEVSebastian Huber2012-05-112-0/+10

* Filesystem: PR1893: Fix write and truncate handlerSebastian Huber2012-05-119-37/+137
| | | | | Space that grows due to truncate or write offsets beyond the current file size must be zero filled.
* Filesystem: PR1871: Fix O_APPENDSebastian Huber2012-05-118-143/+33
|
* Filesystem: PR1398: Fix lseek() mechanicSebastian Huber2012-05-1123-391/+166
| | | | | | | | | | | | According to POSIX the lseek() function shall not, by itself, extend the size of a file. Remove the size field of rtems_libio_t. A file has only one size but may have multiple open file descriptors. Thus a file size field in the file descriptor may lead to inconsistencies. New default handlers rtems_filesystem_default_lseek_file() and rtems_filesystem_default_lseek_directory().
* Score ISR - Minimize Capabilities When Not Simple VectoredJoel Sherrill2012-05-094-9/+21
| | | | | | | | | | | In particular CPU_INTERRUPT_NUMBER_OF_VECTORS and CPU_INTERRUPT_MAXIMUM_VECTOR_NUMBER are only used on Simple Vectored Architectures, so do not depend on them being defined. This disables as much as possible that is specific to the Simple Vectored Model and not expected to be used on architectures which use the Programmable Interrupt Controller model for interrupt handler vectoring.
* Score Semaphore - Need Semaphore Seize Body When Multiprocessing is EnabledJoel Sherrill2012-05-091-1/+1
| | | | mptests did not link without this modification.
* rbtree: API changes. Remove rbtree control node from RBTree_Next.Gedare Bloom2012-05-087-34/+19
| | | | | | | | | | | | The implementation of RBTree_Next was using an awkward construction to detect and avoid accessing the false root of the red-black tree. To deal with the false root, RBTree_Next was comparing node parents with the control node. Instead the false root can be detected by checking if the grandparent of a node exists; the grandparent of the tree's true root is NULL by definition so the root of the tree is found while walking up the tree by checking for the non-existence of a grandparent. This change propagates into the predecessor/successor and iterate functions.
* PR2061: RBTree: updating min and max on insert with duplicatesGedare Bloom2012-05-081-1/+6
| | | | | | | When inserting to a red-black tree with duplicates the min and max pointers are not updated properly. We need to check the key of the min/max node against the insert node since the insert point could be the child of a node with an identical key to the min/max node.
* PR2060: RBTree: updating min and max on extract pathGedare Bloom2012-05-081-17/+9
| | | | | | During node extraction from a red-black tree the min and max values are updated incorrectly. We need to use the successor/predecessor functions to find the next/previous node when we remove the min/max from the tree.
* score/rbtree: eliminate unused function _RBTree_Peek.Gedare Bloom2012-05-083-68/+1

* rbtree: API ChangesGedare Bloom2012-05-082-11/+76
| | | | | Make default for rtems_rbtree functions be unprotected (preemption enabled) unless an unprotected variant e.g. rtems_rbtree_xxx_unprotected is available.

* Filesystem: Remove per file descriptor semaphoreSebastian Huber2012-05-043-29/+6
| | | | | | | | | The per file descriptor semaphore (field of rtems_libio_t) is unused in RTEMS. There is a considerable memory overhead due to that. A semaphore needs roughly 124 bytes which is huge compared to the approximately 72 bytes for the file descriptor structure itself. Device drivers can create their own synchronization primitives in the open handler on demand.

* General - Remove extraneous blank line in license messageJoel Sherrill2012-05-031-0/+0
| | | | | | | | | | | | | Many files had an extra blank line in the license text found in the file header. This patch removes that line. * The license and distribution terms for this file may be * found in the file LICENSE in this distribution or at * * http://www.rtems.com/license/LICENSE. The script that did this also turned off execute permission when it was turned on incorrectly.
* IMFS: Update IMS_assert check when RTEMS_DEBUG is enabled.Chris Johns2012-04-281-1/+1
| | | | Update the assert macro to the new IMFS_jnode_t.

* score: Remove _Stack_Adjust_size()Sebastian Huber2012-04-242-30/+0
| | | | | | | | | | The increase of the stack size by CPU_STACK_ALIGNMENT in _Thread_Stack_Allocate() is disadvantageous. This may lead to a huge over allocation for specialized stack allocators. The CPU_STACK_ALIGNMENT is at most 16 on all current RTEMS CPU ports. The mimimum stack size ensured by _Stack_Ensure_minimum() must be considerable larger than this value, otherwise stack overflows will likely occur. Thus the _Stack_Adjust_size() is also superfluous.
* nfsclient: Use UID and GID of NFS handleSebastian Huber2012-04-231-10/+10
| | | | Use UID and GID of the NFS handle for node and symbolic link creation.
* nfsclient: POSIX conformanceSebastian Huber2012-04-231-9/+37
| | | | | According to POSIX the read() call should return the maximum number of bytes available for regular files.
