- 2006-02-12 Paul Jackson <pj@sgi.com>
* Republished as Open Source under LGPL license
- 2005-09-22 Paul Jackson <pj@sgi.com>
* Added "Using Cpusets with Hyper-Threads" section
* Added to "System Error Numbers"
* Various minor formatting changes
- 2005-04-05 Paul Jackson <pj@sgi.com>
* Added "Identifying Cpuset Support" section
* Added "System Error Numbers" section
* Added cpuset_mountpoint() method
* Note kernel GFP_ATOMIC allocations can go outside cpuset
* Refine overview on various ways to manipulate cpusets
* Example creation of a cpuset and running a shell in it
* The cpuset_c_{rel_to_sys,sys_to_rel}_{cpu,mem} routines
accept NULL to mean the current cpuset
* Cpuset text representations with empty bitmasks can be imported
* Failed cpuset_modify and cpuset_create calls no longer leave
half finished changes around
* The cpuset --family command has a new option, --exclude, that
excludes any CPUs already used by child cpusets from the new
family of cpusets being created
- 2005-03-24 Paul Jackson <pj@sgi.com>
* Added cpuset_addr2node to map virtual address to node holding that page
- 2005-01-14 Paul Jackson <pj@sgi.com>
* Added cpuset --map option (useful side affect: rebuilds cpunodemap)
* Added init script to build /var/run/cpunodemap at boot
* Change libcpuset to ensure it makes /var/run/cpunodemap world readable
* Explain /dev/cpuset file system permission model in more detail
* Document page and slab cache special /dev/cpuset files
- 2004-11-24 Paul Jackson <pj@sgi.com>
* No longer need to link with -pthread, still thread safe if do
* Standardized format of cpuset Text Representation
* No longer need both CPU and MEM in Text Representation; if just one
of them, the other defaults to the equivalent local resources
* New cpuset command options --size, --family to make it easy to create
a set of sized and named non-overlapping child cpusets
* /sbin/cpuset_release_agent added - setting notify_on_release will now
cause abandoned cpusets to be removed automatically
* Fix crash in cpuset_mems_weight
* Cpuset_pin memory placement changed - allows entire cpuset, not just
the one node local to the pinned cpuset.
* Removed rest of runon source code from ProPack 4 source tree - use taskset
* Cpuset pathname evaluation changed in libcpuset - if cpuset path doesn't
start with slash '/', then is relative to current task cpuset, not /dev/cpuset
* Fix libcpuset memory leak in cpuset_reattach().
- 2004-11-10 Paul Jackson <pj@sgi.com>
* Change return of cpuset_localcpus(), cpuset_localmems() and
cpuset_unpin() from 'void' to 'int', so can indicate success/failure
* Added wide spread usage of errno's ENOSYS, ENODEV if cpusets not
supported by kernel, or /dev/cpuset not mounted.
- 2004-11-09 Paul Jackson <pj@sgi.com>
* Rework -i, -I options substantially.
- 2004-11-07 Paul Jackson <pj@sgi.com>
* Added cpuset_cpu2node() mapping cpu to nearest memory node.
* Note demise of /dev/hw hardware graph (had been in SGI 2.4 kernels)
* Added Basic cpuset functions, marked existing functions Advanced
The basic functions are: cpuset_pin, cpuset_size, cpuset_where, cpuset_unpin.
- 2004-11-07 Paul Jackson <pj@sgi.com>
* Reorganize cpuset_function usage and [optional] tag discussion
- 2004-11-07 Paul Jackson <pj@sgi.com>
* More notes comparing cpumemsets for 2.4 Linux with cpusets
- 2004-11-07 Paul Jackson <pj@sgi.com>
* First published as proprietary code by Silicon Graphics, Inc.
