   1 2009-06-22 Brian Behlendorf <behlendorf1@llnl.gov>
   2
   3         * : Tag spl-0.4.4
   4
   5         * : Added SLES10 support.  This includes all compatibility
   6         changes to support 2.6.16 based kernels and the required
   7         build system improvements.
   8
   9         * : Build System changes for SLES10:
  10         - Exclude -obj when detecting installed kernel source.
  11         - Detect -obj directory for out of tree kernel builds.
  12         - Allow kernel build system to set CC to ensure -m64 is set properly.
  13           This is an issue on 64-bit SLES systems which by default always
  14           build 32-bit binaries (unlike RHEL/Fedora which default to 64-bit)
  15
  16         * : Configure Checks added for SLES10:
  17         - div64_64() renamed to div64_u64() as of 2.6.26.
  18         - global_page_state() fuction was introduced in 2.6.18 kernels.
  19           The earlier 2.6.16 based SLES10 must not try and use it,
  20           thankfully get_zone_counts() is still available.
  21         - monotonic_clock() is unavailable __gethrtime() must perform the
  22           HZ division as an 'unsigned long long' because the SPL only
  23           implements __udivdi3(), and not __divdi3() for 'long long'
  24           division on 32-bit arches.
  25         - mutex_lock_nested() was introduced as part of the mutex
  26           validator in 2.6.18, when it is unavailable it is safe to
  27           fallback to using a plain mutex_lock().
  28         - SLES specific API change to vfs_unlink() and vfs_rename() which
  29           added a 'struct vfsmount *' argument.  This was for something
  30           called the linux-security-module, but it appears that it was
  31           never adopted upstream.
  32         - spl_device_create() correctly mapped to class_device_create()
  33           for 2.6.13 to 2.6.17 based kernels, this is the preferred API.
  34         - Prior to 2.6.17 there were no *_pgdat helper functions in
  35           mm/mmzone.c.  Instead for_each_zone() operated directly on
  36           pgdat_list which may or may not have been exported depending on
  37           how your kernel was compiled.  A configure check was added to
  38           determine if you have the helpers or not, and if the needed
  39           symbols are exported.  If they are not exported then they are
  40           dynamically aquired at runtime by kallsyms_lookup_name().
  41
  42         * : Packaging changes for SLES10
  43         - Properly honor --prefix in build system and rpm spec file.
  44         - Add '--define require_kdir' to spec file to support building
  45           rpms against kernel sources installed in non-default locations.
  46         - Add '--define require_kobj' to spec file to support building
  47           rpms against kernel object installed in non-default locations.
  48         - Stop suppressing errors in autogen.sh script.
  49         - Improved logic to detect missing kernel objects when they are
  50           not located with the source.  This is the common case for SLES
  51           as well as in-tree chaos kernel builds and is done to simply
  52           support for multiple arches.
  53         - Moved spl-devel build products to /usr/src/spl-<version>, a
  54           spl symlink is created to reference the last installed version.
  55         - Allow checking for exported symbols in both Module.symvers
  56           and Module.symvers.  My stock SLES kernel ships an objects
  57           directory with Module.symvers, yet produces a Module.symvers
  58           in the local build directory.
  59
  60         * : Added powerpc64 support.
  61         - Enable builds for powerpc64 ISA type.
  62         - Add DIV_ROUND_UP and roundup macros if unavailable.
  63         - Cast 64-bit values for %lld format string to (long long) to
  64           quiet compile warning.
  65
  66         * module/splat/splat-ctl.c: Proper ioctl() 32/64-bit binary
  67           compatibility.  We need to ensure the ioctl data itself is always
  68           packed the same for 32/64-bit binaries.  Additionally, the correct
  69           thing to do is encode this size in bytes as part of the command
  70           using _IOC_SIZE().
  71
  72         * modules/spl/spl-kmem.c: Fixed a long standing bug in the debug
  73           tracing.  The tcd_for_each() macro expected a NULL to terminate
  74           the trace_data[i] array but this was only ever true due to luck.
  75           All trace_data[] iterators are now properly capped by TCD_TYPE_MAX.
  76
  77         * modules/spl/spl-kmem.c: To simplify debugging all symbols aquired
  78           dynamically using spl_kallsyms_lookup_name() are initially poisoned
  79           with SYMBOL_POISON.
  80
  81 2009-03-20 Brian Behlendorf <behlendorf1@llnl.gov>
  82
  83         * : Tag spl-0.4.3
  84
  85         * configure.ac, *Makefile.am: Build system update.  This includes
  86         resolving various build issues and adding support for the remaining
  87         common build targets.  Available targets now include:
  88
  89         - make all        # Build everything
  90         - make install    # Install everything
  91         - make clean      # Clean up build products
  92         - make distclean  # Clean up everything
  93         - make dist       # Create package tarball
  94         - make srpm       # Create package source RPM
  95         - make rpm        # Create package binary RPMs
  96         - make tags       # Create ctags and etags for everything
  97
  98         Extra care was taken to ensure that the source RPMs are fully
  99         rebuildable against Fedora/RHEL/Chaos kernels.  To build binary
 100         RPMs from the source RPM for your system simply run:
 101
 102         rpmbuild --rebuild spl-x.y.z-1.src.rpm
 103
 104         This will produce two binary RPMs with correct 'requires'
 105         dependencies for your kernel.  One will contain all zpl modules
 106         and support utilities, the other is a devel package for compiling
 107         additional kernel modules which are dependent on the spl.
 108
 109         spl-x.y.z-1_<kernel version>.x86_64.rpm
 110         spl-devel-x.y.2-1_<kernel version>.x86_64.rpm
 111
 112         * : FC10 (linux-2.6.27.19) and i686 compatibility update.  The
 113         list of support platforms has been extended to include FC10
 114         systems and x86 architectures.  It should be noted that kernels
 115         older the 2.6.27.19 should work but have not have not been tested.
 116
 117         * configure.ac: Fix build issue preventing spl_config.h from being
 118         cleanly included by dependent packages.
 119
 120         * module/spl/spl-taskq.c: Fix taskq_wait() not waiting bug.
 121
 122         * module/spl/spl-xdr.c: Add XDR implementation provided by Ricardo
 123         Correia from Sun.
 124
 125         * module/spl/spl-kmem.c: Linux VM integration cleanup.
 126
 127         * module/spl/spl-kmem.c: Slab cache improvements and fixes.
 128
 129         * modules/splat/*: Include additional SPLAT regression tests.
 130
 131         * : Various bug fixes are more clearly detailed in the git
 132         commit logs.  For a detailed summary of changes post version
 133         0.4.2 check the git commit logs.

 137 2009-02-05 Brian Behlendorf <behlendorf1@llnl.gov>
 138
 139         * : Tag spl-0.4.2
 140
 141         * module/spl/spl-kmem.c include/sys/kmem.h: Slab cache improvements:
 142           - Implement kmem cache alignment.
 143           - Implement slab ageing.
 144           - Optimized slab packing algorithm.
 145           - Fixed deadlock due to calling call kv_free() under the skc_lock.
 146           - Added additional SPLAT test cases
 147           - Performance optimizations
 148
 149         * module/spl/spl-kmem.c include/sys/kmem.h: Linux VM integration.
 150         The Solaris global VM symbols minfree, desfree, lotsfree, needfree,
 151         swapfs_minfree, swapfs_reserve, availrmem, freemem, and physmem are
 152         now available and loosely integrating with the Linux VM.  Some
 153         tuning will undoubtably be needed and these tunables are available
 154         in /proc/sys/kernel/spl/vm/* for this very reason.
 155
 156         * config/spl-build.m4: New configure checks needed when building
 157         against 2.6.27+ kernels.  More work is needed here.
 158
 159         * : Minor cleanup see the 'git log' for full details.
 160
 161 2009-01-21 Brian Behlendorf <behlendorf1@llnl.gov>
 162
 163         * : Tag spl-0.4.1
 164
 165         * : Implement ksid_*, ddi_strto*, and system taskq functionality.
 166         In addition, several other small Solaris compatibility changes
 167         were made, see the 'git log' for full details.
 168
 169 2008-11-26 Brian Behlendorf <behlendorf1@llnl.gov>
 170
 171         * : Tag spl-0.4.0 (Development now done with Git)
 172
 173         * : Imported SPL SVN repo in to Git Repo for core development.
 174
 175 2008-11-26 Brian Behlendorf <behlendorf1@llnl.gov>
 176
 177         * : Tag spl-0.3.5
 178
 179         * : Include META file support.
 180
 181 2008-11-05 Jim Garlick <garlick@llnl.gov>
 182
 183         * : Add autogen.sh products.
 184
 185         * configure.ac : Use AC_CONFIG_AUX_DIR to put autograph products
 186         in ./auotconf.
 187
 188         * autogen.sh : Use --copy to avoid symlinks, remove error
 189         redirection, run aclocal before libtoolize.
 190
 191 2008-11-13 Brian Behlendorf <behlendorf1@llnl.gov>
 192
 193         * include/sys/sunddi.h, modules/spl/spl-module.c : Removed default
 194         udev support from sunddi implementation because it uses GPL-only
 195         symbols.  This support is optionally available for SPL consumers
 196         if they define HAVE_GPL_ONLY_SYMBOLS and license their module as
 197         GPL using the MODULE_LICENSE("GPL") macro.
 198
 199 2008-11-05 Brian Behlendorf <behlendorf1@llnl.gov>
 200
 201         * : Tag spl-0.3.4
 202
 203         * : Coverity clean.
 204
 205         * : Patches from Ricardo M. Correia <Ricardo.M.Correia@sun.com>
 206         applied with minor revisions:
 207
 208                 spl-00-rm-gpl-symbol-notifier_chain.patch
 209                 spl-01-rm-gpl-symbol-set_cpus_allowed.patch
 210                 spl-02-rm-gpl-symbols-device.patch
 211                 spl-03-rm-gpl-symbol-ktime_get_ts.patch
 212                 spl-04-fix-taskq-spinlock-lockup.patch
 213                 spl-05-div64.patch
 214                 spl-06-atomic64.patch
 215                 spl-07-kmem-cleanup.patch
 216                 spl-08-km-sleep-nofail.patch
 217                 spl-09-fix-kmem-track-oops.patch
 218                 spl-10-fix-assert-verify-ndebug.patch
 219
 220 2008-06-30 Brian Behlendorf <behlendorf1@llnl.gov>
 221
 222         * : Tag spl-0.3.3
 223
 224         * : modules/sys/kmem-slab.c : Refined SPL slab to include
 225         per-cpu caches, removed internal hash, other general
 226         performance improvements.  Much work remain but it's pretty
 227         good for an initial implementation.
 228
 229 2008-06-13 Brian Behlendorf <behlendorf1@llnl.gov>
 230
 231         * : modules/sys/kmem-slab.c : Re-implemented the slab to no
 232         longer be based on the linux slab but to be it's own complete
 233         implementation.  The new slab behaves much more like the
 234         Solaris slab than the Linux slab.
 235
 236 2008-06-04 Brian Behlendorf <behlendorf1@llnl.gov>
 237
 238         * : Tag spl-0.3.2
 239
 240         * : Extensive improvements to the build system to detect kernel
 241         API changes so we can flexibly build with a wider range of kernel
 242         versions.  The code has now been testing with the 2.6.18-32chaos
 243         and 2.6.25.3-18.fc9 kernels, however we should also be compatible
 244         with other kernels in the range of 2.6.18-2.6.25.
 245
 246 2008-05-25 Brian Behlendorf <behlendorf1@llnl.gov>
 247
 248         * configure.ac, autoconf/* : Initial pass at resolving
 249         API changes introduced by kernels newer than 2.6.18.
 250
 251 2008-05-21 Brian Behlendorf <behlendorf1@llnl.gov>
 252
 253         * : Tag spl-0.3.1
 254
 255         * : License headers including URCL added for release.
 256
 257 2008-05-21 Brian Behlendorf <behlendorf1@llnl.gov>
 258
 259         * : Tag spl-0.3.0
 260
 261         * configure.ac: Improved autotools support.
 262
 263 2008-04-26 Brian Behlendorf <behlendorf1@llnl.gov>
 264
 265         * include/sys/mutex.h : Implemented a close approximation
 266         of adaptive mutexes.  These changes however required me to
 267         export a new symbol from the kernel proper 'task_curr()'
 268         which means we are now dependant on a patched kernel.
 269
 270 2008-04-24 Brian Behlendorf <behlendorf1@llnl.gov>
 271
 272         * : Tag spl-0.2.1
 273
 274         * modules/spl/spl-proc.c : Add /proc/sys/spl/version.
 275
 276 2008-04-24 Herb Wartens <wartens2@llnl.gov>
 277
 278         * include/sys/kmem.h : Make sure that when calling __vmem_alloc
 279         that we do not have __GFP_ZERO set.  Once the memory is allocated
 280         then zero out the memory if __GFP_ZERO is passed to
 281         __vmem_alloc.
 282
 283 2008-04-16 Herb Wartens <wartens2@llnl.gov>
 284
 285         * modules/spl/spl-kmem.c : Make sure to disable interrupts
 286         when necessary to avoid deadlocks.  We were seeing the deadlock
 287         when calling kmem_cache_generic_constructor() and then an interrupt
 288         forced us to end up calling kmem_cache_generic_destructor()
 289         which caused our deadlock.
 290
 291 2008-02-26 Brian Behlendorf <behlendorf1@llnl.gov>
 292
 293         : Initial commit of the solaris porting layer (spl).  Included
 294         in addition to the source is an initial autoconf / configure
 295         style build system.
