Update #3706
|
|
Use a processor-specific interrupt frame during context switches in case
the executing thread is longer executes on the processor and the heir
thread is about to start execution. During this period we must not use
a thread stack for interrupt processing.
Update #2809.
|
|
Store the floating-point unit property in the thread control block
regardless of the CPU_HARDWARE_FP and CPU_SOFTWARE_FP settings. Make
sure the floating-point unit is only enabled for the corresponding
multilibs. This helps targets which have a volatile only floating point
context like SPARC for example.
|
|
|
|
Tested and implemented on ARM, m68k, PowerPC and SPARC. Other
architectures need more work.
|
|
Use a per-CPU thread dispatch disable level. So instead of one global
thread dispatch disable level we have now one instance per processor.
This is a major performance improvement for SMP. On non-SMP
configurations this may simplifiy the interrupt entry/exit code.
The giant lock is still present, but it is now decoupled from the thread
dispatching in _Thread_Dispatch(), _Thread_Handler(),
_Thread_Restart_self() and the interrupt entry/exit. Access to the
giant lock is now available via _Giant_Acquire() and _Giant_Release().
The giant lock is still implicitly acquired via
_Thread_Dispatch_decrement_disable_level().
The giant lock is only acquired for high-level operations in interrupt
handlers (e.g. release of a semaphore, sending of an event).
As a side-effect this change fixes the lost thread dispatch necessary
indication bug in _Thread_Dispatch().
A per-CPU thread dispatch disable level greatly simplifies the SMP
support for the interrupt entry/exit code since no spin locks have to be
acquired in this area. It is only necessary to get the current
processor index and use this to calculate the address of the own per-CPU
control. This reduces the interrupt latency considerably.
All elements for the interrupt entry/exit code are now part of the
Per_CPU_Control structure: thread dispatch disable level, ISR nest level
and thread dispatch necessary. Nothing else is required (except CPU
port specific stuff like on SPARC).

Move implementation specific parts of thread.h and thread.inl into new
header file threadimpl.h. The thread.h contains now only the
application visible API.
Remove superfluous header file includes from various files.

This patch is a task from GCI 2012 which improves the Doxygen
comments in the RTEMS source.
http://www.google-melange.com/gci/task/view/google/gci2012/7983216

This file contains the parts of <rtems/score/userext.h> that are only
necessary for the RTEMS implementation.
|
|
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.

a BSP (c4xsim) supporting the simulator included with gdb. This port
was done by Joel Sherrill and Jennifer Averett of OAR Corporation.
Also included with this port is a space/time optimization to eliminate
FP context switch management on CPUs without hardware or software FP.
An issue with this port was that sizeof(unsigned32) = sizeof(unsigned8)
on this CPU. This required addressing alignment checks and assumptions
as well as fixing code that assumed sizeof(unsigned32) == 4.
