Sebastian Huber dcd97c77f0 sparc: Add atomic support for SPARC V8 
Use SWAP instruction with one lock for the system in the SMP case.

Sebastian Huber 6f90ef752d score: Remove volatile from asm statements 
The instructions to get the processor current index have no
side-effects.

Sebastian Huber 24bf11eca1 score: Add CPU counter support 
Add a CPU counter interface to allow access to a free-running counter.
It is useful to measure short time intervals.  This can be used for
example to enable profiling of critical low-level functions.

Add two busy wait functions rtems_counter_delay_ticks() and
rtems_counter_delay_nanoseconds() implemented via the CPU counter.

Sebastian Huber bab16de267 score: Change debug helper functions 
Rename rtems_internal_error_description() to
rtems_internal_error_text().  Rename rtems_fatal_source_description() to
rtems_fatal_source_text().  Rename rtems_status_code_description() to
rtems_status_text().  Remove previous implementation of
rtems_status_text().

Sebastian Huber 97cf623d4a sparc: Save/restore only non-volatile context 
The _CPU_Context_switch() is a normal function call.  The following
registers are volatile (the caller must assume that the register
contents are destroyed by the callee) according to "SYSTEM V APPLICATION
BINARY INTERFACE - SPARC Processor Supplement", Third Edition: g1, o0,
o1, o2, o3, o4, o5.  Drop these registers from the context.

Ensure that offset defines match the structure offsets.

Sebastian Huber 62c5c4a564 bsps/sparc: Fix ambapp_find_by_idx() 
The expression "*pi++" post-increments the pointer (not the value).
 2014-02-11 12:54:24 +01:00
Sebastian Huber 0df8d7f20d bsps/arm: Use Global Timer for Cortex-A9 MPCore 
Use the Global Timer for the Cortex-A9 MPCore clock driver instead of
the Private Timer.  This enables a consistent nanoseconds since last
context switch value across all processors.

the same time.

Avoid magic delay loops.

Sebastian Huber 3ef2d175fa bsp/leon3: Install IPI handler early 
Install inter-processor interrupt (IPI) handler before secondary CPUs
are started.  This ensures that secondary CPUs fetch the newly installed
handler.
