This commit adds support for project_framework_component_* parameter matching. This is the first step in allowing the same framework name in multiple projects. This change also bumps the MCA component version to 2.1.0. All master frameworks have been updated to use the new component versioning macro. An mca.h has been added to each project to add a project specific versioning macro of the form PROJECT_MCA_VERSION_2_1_0. Signed-off-by: Nathan Hjelm <hjelmn@me.com>

|
* High resolution timer / cycle counter
|
|
*
|
|
* High resolution timer / cycle counter interface. This interface is
|
|
* intended to hide the system-dependent nature of timers that provide
|
|
* higher resolution and lower calling cost than gettimeofday().
|
|
* Unlike most component interfaces, there should only ever be one
|
|
* component available to be built on a particular platform.
|
|
* Therefore, a number of #defines are available to determine how well
|
|
* the platform supports high resolution timers:
|
|
*
|
|
* <UL>
|
|
* <LI><PRE>OPAL_TIMER_CYCLE_NATIVE</PRE> Whether
|
|
* opal_timer_base_get_cycle() is implemented directly or computed
|
|
* from some other data (such as a high res timer)</LI>
|
|
* <LI><PRE>OPAL_TIMER_CYCLE_SUPPORTED</PRE> Whether
|
|
* opal_timer_base_get_cycle() is supported on the current
|
|
* platform.</LI>
|
|
* <LI><PRE>OPAL_TIMER_USEC_SUPPORTED</PRE> Whether
|
|
* opal_timer_base_get_usec() is supported on the current
|
|
* platform or implemented on top of gettimeofday(), which
|
|
* may be unsuitable for some uses.
|
|
* </UL>
|
|
*
|
|
* The cycle count may not be the cycle count of the CPU itself, if
|
|
* there is another sufficiently close counter with better behavior
|
|
* characteristics (like the Time Base counter on many Power/PowerPC
|
|
* platforms). The function opal_timer_base_get_freq() returns the
|
|
* frequency of the cycle counter in use, *NOT* the frequency of the
|
|
* main CPU.
|
|
*
|
|
* Unless otherwise noted, no attempt is made to cope with the the
|
|
* differences in counters on SMP machines. If your process switches
|
|
* CPUs, your timer results may change.
|
|
*
|
|
* Build time priorities are allocated as follows:
|
|
*
|
|
* - 0 gettimeofday() wrapper
|
|
* - 10 Assembly timers with bad frequency search (Linux)
|
|
* - 20 NIC software stack (QSNet, Myrinet?)
|
|
* - 30 Operating systems with native interfaces
