* score: Add <rtems/score/cpuimpl.h>Sebastian Huber2016-11-071-0/+1
| | | | | | The aim of this file is to encapsulate CPU port implementation details. This helps to hide implementation details from <rtems.h> which indirectly includes <rtems/score/cpu.h>.
* score: Use atomic API for SMP lockSebastian Huber2014-02-171-1/+0
| | | | | Use a ticket lock implementation based on atomic operations. Delete CPU port specific SMP lock implementations.
* score: Add CPU counter supportSebastian Huber2014-02-141-0/+1
| | | | | | | | | 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.
* smp: New SMP lock APISebastian Huber2013-05-311-0/+1
| | | | | | | | | | | | | | Move the SMP lock implementation to the CPU port. An optimal SMP lock implementation is highly architecture dependent. For example the memory models may be fundamentally different. The new SMP lock API has a flaw. It does not provide the ability to use a local context for acquire and release pairs. Such a context is necessary to implement for example the Mellor-Crummey and Scott (MCS) locks. The SMP lock is currently used in _Thread_Disable_dispatch() and _Thread_Enable_dispatch() and makes them to a giant lock acquire and release. Since these functions do not pass state information via a local context there is currently no use case for such a feature.
* Remove All CVS Id Strings Possible Using a ScriptJoel Sherrill2012-05-111-4/+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.

<corsepiu@faw.uni-ulm.de> which implements automake support for some score/cpu/<RTEMS_CPU> subdirectories and fixes a few minor configuration bugs. To apply: rm -rf c/src/exec/score/cpu/a29k/wrap rm -rf c/src/exec/score/cpu/hppa1.1/wrap rm -rf c/src/exec/score/cpu/i386/wrap rm -rf c/src/exec/score/cpu/mips64orion/wrap rm -rf c/src/exec/score/cpu/no_cpu/wrap patch -p1 < rtems-rc-19991123-rc-2.diff.gz Notes: * I don't see a possiblity to convert the powerpc subdirectory in its current layout to automake the time being. * Besides the fact that this subdirectory is not in single-tree building layout, the actual showstopper is the ifeq $(RTEMS_CPU_MODEL),mpc750) gmake-conditional in powerpc/Makefile.in, which automake (correctly) refuses to handle. * The problem is *not* specific to the powerpc. Other CPUs basically have similar problems (SH:sh7032 vs sh7045, SPARC: erc32.h in score/cpu/sparc), but have been lucky to get around real issues (cf. configuration files below score/cpu/sh/). * From a configuration focused POV this problem boils down to a file/subdirectory selection problem: ppc: 1 or others sh: 1 out of 2 sparc: 1 out of 1 Automake's means to implement such behavior is using conditionals to be evaluated at configuration-time. The old configuration scheme however used make-time conditionals. The SH port was lucky to get around this issue because it applies a selection from a limited set of possible selections, the powerpc however applies a selection from an unlimited set, based on data not being available at configuration time. * Currently I only see two general solutions: 1) make RTEMS_CPU_MODEL available at configuration time, ie. replace make-time configuration by configuration-time configuration 2) Perform the selection at build-time, i.e. always install all files, but use #ifdef #else #endif in source files. This is what the m68k has exploited at other locations inside of the source-tree. => This directory is the last one remaining not using automake below the whole exec/ hierarchy.
