Changes paffinity interface to use a cpu mask for available/preferred cpus rather than the current coarse grained paffinity that lets the OS choose which processor. Macros for setting and clearing masks are provided. Solaris and windows changes have not been made. Solaris subdirectory has some suggested changes - however the relevant man pages for the Solaris 10 APIs have some ambiguity regarding order in which one create and sets a processor set. As we did not have access to a solaris 10 machine we could not test to see the correct way to do the work under solaris. This commit was SVN r14887.

===========================================================================
|
|
|
|
This file contains the main features as well as overviews of specific
|
|
bug fixes (and other actions) for each version of PLPA since
|
|
version 1.0.
|
|
|
|
1.1
|
|
---
|
|
|
|
- New command: plpa-taskset. It is intended as a drop-in replacement
|
|
for the "taskset" command, except it also understands sockets and
|
|
cores. See the man page for more details.
|
|
- Renamed "plpa_info" to "plpa-info".
|
|
- Added PLPA_{MAJOR|MINOR|RELEASE}_VERSION integer macros in plpa.h.
|
|
This release, they have the values of 1, 1, and 0, respectively.
|
|
- Add new API functions to map from (socket,core) back and forth from
|
|
the Linux virtual processor ID. Thanks to AMD for the initial code
|
|
contribution that made this possible. See the man page for
|
|
plpa_map_to_processor_id(3) as a starting point for more
|
|
information.
|
|
- Added man pages for executables and API functions.
|
|
- Various fixes to "included" mode.
|
|
|
|
|
|
1.0.5
|
|
-----
|
|
|
|
- Fix an issue where the PLPA get/set affinity functions would only
|
|
operate on the current process; the PID argument to these functions
|
|
was effectively ignored.
|
|
|
|
|
|
1.0.4
|
|
-----
|
|
|
|
- Fix some 64 bit issues. Thanks to David Creasy for reporting the
|
|
problems.
|
|
- Fix plpa.h to be C++-friendly. Thanks to Emmanuel Paris for
|
|
pointing out this problem.
|
|
|
|
|
|
1.0.3
|
|
-----
|
|
|
|
- Resolve some sizing / units ambiguities that mistakenly did not make
|
|
it into 1.0.1. Thanks to Bert Wesarg for pointing these problems out.
|
|
|
|
|
|
1.0.2
|
|
-----
|
|
|
|
- Ensure that plpa_sched_[set|get]affinity() returns 0 upon success.
|
|
Thanks to David Creasy for bringing this to our attention.
|
|
|
|
|
|
1.0.1
|
|
-----
|
|
|
|
- Specify that cpusetsize should be in units of bytes and add some
|
|
missing "* 8"'s in plpa_dispatch.c.
|
|
|
|
|
|
1.0
|
|
---
|
|
|
|
- Initial release.
|
|
|
|
|
|
0.9a2
|
|
-----
|
|
|
|
- Change the back-end type of the plpa_bitmask_t to unsigned long
|
|
instead of unsigned char to avoid an endian problem.
|
|
- No longer attempt to set the affinity in plpa_api_probe() to avoid a
|
|
possible race condition (setting it after getting it).
|
|
- Fix PLPA_CPU_ZERO macro. Thanks to Bogdan Costescu for pointing
|
|
this out.
|
|
|
|
|
|
0.9a1
|
|
-----
|
|
|
|
Initial public release.
