   1 2009-02-05 Brian Behlendorf <behlendorf1@llnl.gov>
   2
   3         * : Tag spl-0.4.2
   4
   5         * module/spl/spl-kmem.c include/sys/kmem.h: Slab cache improvements:
   6           - Implement kmem cache alignment.
   7           - Implement slab ageing.
   8           - Optimized slab packing algorithm.
   9           - Fixed deadlock due to calling call kv_free() under the skc_lock.
  10           - Added additional SPLAT test cases
  11           - Performance optimizations
  12
  13         * module/spl/spl-kmem.c include/sys/kmem.h: Linux VM integration.
  14         The Solaris global VM symbols minfree, desfree, lotsfree, needfree,
  15         swapfs_minfree, swapfs_reserve, availrmem, freemem, and physmem are
  16         now available and loosely integrating with the Linux VM.  Some
  17         tuning will undoubtably be needed and these tunables are available
  18         in /proc/sys/kernel/spl/vm/* for this very reason.
  19
  20         * config/spl-build.m4: New configure checks needed when building
  21         against 2.6.27+ kernels.  More work is needed here.
  22
  23         * : Minor cleanup see the 'git log' for full details.
  24
  25 2009-01-21 Brian Behlendorf <behlendorf1@llnl.gov>
  26
  27         * : Tag spl-0.4.1
  28
  29         * : Implement ksid_*, ddi_strto*, and system taskq functionality.
  30         In addition, several other small Solaris compatibility changes
  31         were made, see the 'git log' for full details.
  32
  33 2008-11-26 Brian Behlendorf <behlendorf1@llnl.gov>
  34
  35         * : Tag spl-0.4.0 (Development now done with Git)
  36
  37         * : Imported SPL SVN repo in to Git Repo for core development.
  38
  39 2008-11-26 Brian Behlendorf <behlendorf1@llnl.gov>
  40
  41         * : Tag spl-0.3.5
  42
  43         * : Include META file support.
  44
  45 2008-11-05 Jim Garlick <garlick@llnl.gov>
  46
  47         * : Add autogen.sh products.
  48
  49         * configure.ac : Use AC_CONFIG_AUX_DIR to put autoconf products
  50         in ./auotconf.
  51
  52         * autogen.sh : Use --copy to avoid symlinks, remove error
  53         redirection, run aclocal before libtoolize.
  54
  55 2008-11-13 Brian Behlendorf <behlendorf1@llnl.gov>
  56
  57         * include/sys/sunddi.h, modules/spl/spl-module.c : Removed default
  58         udev support from sunddi implementation because it uses GPL-only
  59         symbols.  This support is optionally available for SPL consumers
  60         if they define HAVE_GPL_ONLY_SYMBOLS and license their module as
  61         GPL using the MODULE_LICENSE("GPL") macro.
  62
  63 2008-11-05 Brian Behlendorf <behlendorf1@llnl.gov>
  64
  65         * : Tag spl-0.3.4
  66
  67         * : Coverity clean.
  68
  69         * : Patches from Ricardo M. Correia <Ricardo.M.Correia@sun.com>
  70         applied with minor revisions:
  71
  72                 spl-00-rm-gpl-symbol-notifier_chain.patch
  73                 spl-01-rm-gpl-symbol-set_cpus_allowed.patch
  74                 spl-02-rm-gpl-symbols-device.patch
  75                 spl-03-rm-gpl-symbol-ktime_get_ts.patch
  76                 spl-04-fix-taskq-spinlock-lockup.patch
  77                 spl-05-div64.patch
  78                 spl-06-atomic64.patch
  79                 spl-07-kmem-cleanup.patch
  80                 spl-08-km-sleep-nofail.patch
  81                 spl-09-fix-kmem-track-oops.patch
  82                 spl-10-fix-assert-verify-ndebug.patch
  83
  84 2008-06-30 Brian Behlendorf <behlendorf1@llnl.gov>
  85
  86         * : Tag spl-0.3.3
  87
  88         * : modules/sys/kmem-slab.c : Refined SPL slab to include
  89         per-cpu caches, removed internal hash, other general
  90         performance improvements.  Much work remain but it's pretty
  91         good for an initial implementation.
  92
  93 2008-06-13 Brian Behlendorf <behlendorf1@llnl.gov>
  94
  95         * : modules/sys/kmem-slab.c : Re-implemented the slab to no
  96         longer be based on the linux slab but to be it's own complete
  97         implementation.  The new slab behaves much more like the
  98         Solaris slab than the Linux slab.
  99
 100 2008-06-04 Brian Behlendorf <behlendorf1@llnl.gov>
 101
 102         * : Tag spl-0.3.2
 103
 104         * : Extensive improvements to the build system to detect kernel
 105         API changes so we can flexibly build with a wider range of kernel
 106         versions.  The code has now been testing with the 2.6.18-32chaos
 107         and 2.6.25.3-18.fc9 kernels, however we should also be compatible
 108         with other kernels in the range of 2.6.18-2.6.25.
 109
 110 2008-05-25 Brian Behlendorf <behlendorf1@llnl.gov>
 111
 112         * configure.ac, autoconf/* : Initial pass at resolving
 113         API changes introduced by kernels newer than 2.6.18.
 114
 115 2008-05-21 Brian Behlendorf <behlendorf1@llnl.gov>
 116
 117         * : Tag spl-0.3.1
 118
 119         * : License headers including URCL added for release.
 120
 121 2008-05-21 Brian Behlendorf <behlendorf1@llnl.gov>
 122
 123         * : Tag spl-0.3.0
 124
 125         * configure.ac: Improved autotools support.
 126
 127 2008-04-26 Brian Behlendorf <behlendorf1@llnl.gov>
 128
 129         * include/sys/mutex.h : Implemented a close approximation
 130         of adaptive mutexes.  These changes however required me to
 131         export a new symbol from the kernel proper 'task_curr()'
 132         which means we are now dependant on a patched kernel.
 133
 134 2008-04-24 Brian Behlendorf <behlendorf1@llnl.gov>
 135
 136         * : Tag spl-0.2.1
 137
 138         * modules/spl/spl-proc.c : Add /proc/sys/spl/version.
 139
 140 2008-04-24 Herb Wartens <wartens2@llnl.gov>
 141
 142         * include/sys/kmem.h : Make sure that when calling __vmem_alloc
 143         that we do not have __GFP_ZERO set.  Once the memory is allocated
 144         then zero out the memory if __GFP_ZERO is passed to
 145         __vmem_alloc.
 146
 147 2008-04-16 Herb Wartens <wartens2@llnl.gov>
 148
 149         * modules/spl/spl-kmem.c : Make sure to disable interrupts
 150         when necessary to avoid deadlocks.  We were seeing the deadlock
 151         when calling kmem_cache_generic_constructor() and then an interrupt
 152         forced us to end up calling kmem_cache_generic_destructor()
 153         which caused our deadlock.
 154
 155 2008-02-26 Brian Behlendorf <behlendorf1@llnl.gov>
 156
 157         : Initial commit of the solaris porting layer (spl).  Included
 158         in addition to the source is an initial autoconf / configure
 159         style build system.
