* librpc: PR2066: Fix for short enumsSebastian Huber2012-06-067-15/+23
| | | | | | | | | | The XDR library has a problem on architectures with short enums like the default ARM EABI. Short enums means that the size of the enum type is variable and the smallest integer type to hold all enum values will be selected. For many enums this is char. The XDR library uses int32_t for enum_t. There are several evil casts from an enum type to enum_t which leads to invalid memory accesses on short enum architectures. A workaround is to add appropriate dummy enum values.

* dosfs: Fix for no space left on device conditionSebastian Huber2012-06-041-3/+5
| | | | | | The file size was wrong in the no space left on device condition. This resulted in turn in a read of an invalid block which lead to an EIO error status.
* libblock: Add read-ahead taskSebastian Huber2012-06-045-130/+293
| | | | | | | | | | | 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.
* powerpc: Simplify context switchSebastian Huber2012-06-042-146/+134
| | | | | | | | | | | | | | | | | | | PowerPC cores with the SPE (Signal Processing Extension) have 64-bit general-purpose registers. The SPE context switch code has been merged with the standard context switch code. The context switch may use cache operations to increase the performance. It will be ensured that the context is 32-byte aligned (PPC_DEFAULT_CACHE_LINE_SIZE). This increases the overall memory size of the context area in the thread control block slightly. The general-purpose registers GPR2 and GPR13 are no longer part of the context. The BSP must initialize these registers during startup (usually initialized by the __eabi() function). The new BSP option BSP_USE_DATA_CACHE_BLOCK_TOUCH can be used to enable the dcbt instruction in the context switch. The new BSP option BSP_USE_SYNC_IN_CONTEXT_SWITCH can be used to enable sync and isync instructions in the context switch. This should be not necessary in most cases.

* ftpd: Set current directory after session closeSebastian Huber2012-05-291-1/+2
| | | | | | The chroot() is an implicit chdir("/"). Set the current directory to "/" after session close. This helps to avoid references to mounted file systems in dynamic media.

* 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.

* 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.

* 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.
