9:54 PM Changeset in rtems [e6c87f7]4.11 by Joel Sherrill <joel.sherrill@…>
POSIX keys now enabled in all configurations. Formerly POSIX keys were only enabled when POSIX threads were enabled. Because they are a truly safe alternative to per-task variables in an SMP system, they are being enabled in all configurations.

9:18 AM Changeset in rtems [718124e]4.11 by Sebastian Huber <sebastian.huber@…>
rtems: Add RTEMS_INTERRUPT_REPLACE A new option RTEMS_INTERRUPT_REPLACE is introduced that permits updating the first interrupt handler for the registered interrupt vector and matching argument. If no match is found, the install function fails with RTEMS_UNSATISFIED. The Interrupt Manager Extension offers interrupt handlers with an argument pointer. It is impossible to update two words (handler and argument) atomically on most architectures. In order to avoid an SMP lock in bsp_interrupt_handler_dispatch() which would degrade the interrupt response time an alternative must be provided that makes it possible to tear-down interrupt sources without an SMP lock. Add RTEMS_INTERRUPT_REPLACE option to Interrupt Manager Extension. This enables a clean tear-down of interrupt sources on SMP configurations. Instead of an interrupt handler removal a replacement handler can be installed to silence an interrupt source. This can be used in contexts that allow no sophisticated synchronization (e.g. in atexit() or fatal handlers).

jffs2: fix unbalanced locking Li Zefan reported an unbalanced locking issue, found by his internal debugging feature on runtime. The particular case he was looking at doesn't lead to a deadlock, as the structure that this lock is embedded in is freed on error. But we should straighten out the error handling. Because several callers of jffs2_do_read_inode_internal() / jffs2_do_read_inode() already handle the locking/unlocking and inode clearing at their own level, let's just push any unlocks/clearing down to the caller. This consistency is much easier to verify.

sparc: Fix CPU counter support The SPARC processors supported by RTEMS have no built-in CPU counter support. We have to use some hardware counter module for this purpose. The BSP must provide a 32-bit register which contains the current CPU counter value and a function for the difference calculation. It can use for example the GPTIMER instance used for the clock driver.
9:48 AM Changeset in rtems [64f4ac2]4.11 by Sebastian Huber <sebastian.huber@…>
bsp/leon3: Add new cache manager implementation The previous implementation used an instruction cache line size of 0, this is a bogus value. Use a instruction cache line size of 64 since the L2 cache may have a line size of 32 or 64. A greater value should cause no harm. Use a FLUSH operation for _CPU_cache_invalidate_instruction_range(). This is a preperation step to support the L2 cache.

New fstest to check rename POSIX conformance This patch is a newer version of the test presented on http://www.rtems.org/pipermail/rtems-devel/2014-February/005318.html Unchecked error cases: - EIO (physical error) - ENOSPC (no space left in the new filepath) - EROFS (already covered on testsuites/fstests/fsrofs01) Untested functionality: - File system lock during rename() operation - If after rename() the link count of a file becomes 0 it should be removed and the space ocupied by the file shall be freed and no longer accessible (the function statvfs() gives "not implemented" on the imfs file system, so this is postponed for now)

Rename _SMP_Request_other_cores_to_shutdown() into _SMP_Request_shutdown(). Add a per-CPU state lock to protect all changes.
