| =========================================================================== |
| |
| 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. |
| |
| 1.3.2 |
| ----- |
| |
| - Removed a clause from AMD's license notice in plpa_map.c by |
| direction from Barry S. Newberger, Ph.D., Assistant General Counsel, |
| Advanced Micro Devices, Inc. per a Red Hat licensing concern |
| (initiated at https://bugzilla.redhat.com/show_bug.cgi?id=530230). |
| Removing this clause alleviates Red Hat's concern, even though this |
| resolution not shown on the above-cited bugzilla ticket. |
| - Julian Seward noticed that PLPA's use of the Valgrind API in the |
| affinity API probe was incorrect and suggested an improvement. Even |
| though we're ramping down PLPA development, I couldn't really ignore |
| the Valgrind author's suggestion! |
| |
| |
| 1.3.1 |
| ----- |
| |
| - Fixed bug identified by Eugene Loh at Sun; plpa-taskset -c ranges |
| were accidentally excluding the processor ID at the top of the |
| range. |
| - For standalone PLPA builds, the .so library is now versioned |
| according to the GNU Libtool guidelines. |
| |
| |
| 1.3 |
| --- |
| |
| - Added --with-valgrind support that allows building support for |
| Valgrind into PLPA (i.e., tell Valgrind to not warn about things |
| that we know are ok). |
| |
| |
| 1.2 |
| --- |
| |
| - Allow mapping from simple/contiguous processor, socket, and core |
| numbers to the corresponding back-end Linux ID (and clean up |
| documentation references between "X number" and "X ID", where X is |
| one of processor, socket, core). |
| - Support CPU hot plugging. |
| - Add explicit control over the PLPA topology information cache. |
| |
| |
| 1.1.1 |
| ----- |
| |
| - Ensure that --enable-included also disables executables by default. |
| Thanks to Brian Curtis for identifying the problem and supplying a |
| patch. |
| - Add ENABLE_EXECUTABLES m4 macro to allow behavior in m4 |
| configuration analogous to "--enable-included --enable-executables". |
| |
| |
| 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 "plpa-taskset --help" 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 documentation for |
| plpa_map_to_processor_id() as a starting point for more |
| information. |
| - 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. |
