* Filesystem: Reference counting for locationsSebastian Huber2012-03-131-198/+141
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | o A new data structure rtems_filesystem_global_location_t was introduced to be used for o the mount point location in the mount table entry, o the file system root location in the mount table entry, o the root directory location in the user environment, and o the current directory location in the user environment. During the path evaluation global start locations are obtained to ensure that the current file system instance will be not unmounted in the meantime. o The user environment uses now reference counting and is protected from concurrent access. o The path evaluation process was completely rewritten and simplified. The IMFS, RFS, NFS, and DOSFS use now a generic path evaluation method. Recursive calls in the path evaluation have been replaced with iteration to avoid stack overflows. Only the evaluation of symbolic links is recursive. No dynamic memory allocations and intermediate buffers are used in the high level path evaluation. No global locks are held during the file system instance specific path evaluation process. o Recursive symbolic link evaluation is now limited by RTEMS_FILESYSTEM_SYMLOOP_MAX. Applications can retrieve this value via sysconf(). o The device file system (devFS) uses now no global variables and allocation from the workspace. Node names are allocated from the heap. o The upper layer lseek() performs now some parameter checks. o The upper layer ftruncate() performs now some parameter checks. o unmask() is now restricted to the RWX flags and protected from concurrent access. o The fchmod_h and rmnod_h file system node handlers are now a file system operation. o The unlink_h operation has been removed. All nodes are now destroyed with the rmnod_h operation. o New lock_h, unlock_h, clonenod_h, and are_nodes_equal_h file system operations. o The path evaluation and file system operations are now protected by per file system instance lock and unlock operations. o Fix and test file descriptor duplicate in fcntl(). o New test fstests/fsnofs01.

* | Milkymist - Increase SOFTUSB_PMEM_SIZE to 8 KBWerner Almesberger2012-03-061-1/+1
|/ | | | | | | | | | | | | We increased PMEM to 8 kB but never updated SOFTUSB_PMEM_SIZE. This didn't have much of an effect because all we used it for was to zero unused program memory - which we should never touch anyway. But now that "usb load" in FN uses SOFTUSB_PMEM_SIZE, this caused it to silently truncate the firmware, producing rather puzzling effects. Signed-off-by: Joel Sherrill <joel.sherrill@oarcorp.com>

* | Avoid NULL dereference in printk() before libchip console initializedJennifer Averett2012-02-234-63/+129
|/ | | | | | | | With the addition of dynamically registered libchip serial devices, there is the need to be able to use printk() before the console driver has initialized the indirect pointer table. This lets printk() support routines call pass a control structure directly without a lookup through the uninitialized indirect one.

* PR 1991/cpukit - attr.c (really mode code) warning reworkJoel Sherrill2012-02-021-2/+2
| | | | | | | | | | | | | | This PR was about a warning for no previous prototype for rtems_interrupt_level_attribute. This method exists (like a few others) to have real bodies for Classic API services implemented as macros. These macros are not available from anything but C and C++. The most explicit use was in the Ada binding but these would be needed from assembly language or any other non-C based language. On top of needing a prototype, the methods were misnamed. They were related to modes. This renames them, moves the file, fixes test code, etc.

* LEON3: CPU index intialization moved to bspstart.cDaniel Hellstrom2012-02-022-18/+18
| | | | | | | | | | | | | | | | | PR 2009/bsps All LEON3/4 systems have a CPU-id, if on a single-CPU system the ID is always zero. On a multicore system it ranges from 0 to 15. The CPU index should always by updated even in a non-MP RTEMS OS since the CPU running RTEMS may not always be CPU0. For example when RTEMS runs on CPU1 and Linux on CPU0 in a mixed ASMP system. The old code executed within the IRQ controller initialization code makes no sense since the ASR register is a CPU register, it has nothing to do with AMBA initialization either.
