|
|
* : Tag spl-0.4.4
|
|
|
|
* : Added SLES10 support. This includes all compatibility
|
|
changes to support 2.6.16 based kernels and the required
|
|
build system improvements.
|
|
|
|
* : Build System changes for SLES10:
|
|
- Exclude -obj when detecting installed kernel source.
|
|
- Detect -obj directory for out of tree kernel builds.
|
|
- Allow kernel build system to set CC to ensure -m64 is set properly.
|
|
This is an issue on 64-bit SLES systems which by default always
|
|
build 32-bit binaries (unlike RHEL/Fedora which default to 64-bit)
|
|
|
|
* : Configure Checks added for SLES10:
|
|
- div64_64() renamed to div64_u64() as of 2.6.26.
|
|
- global_page_state() fuction was introduced in 2.6.18 kernels.
|
|
The earlier 2.6.16 based SLES10 must not try and use it,
|
|
thankfully get_zone_counts() is still available.
|
|
- monotonic_clock() is unavailable __gethrtime() must perform the
|
|
HZ division as an 'unsigned long long' because the SPL only
|
|
implements __udivdi3(), and not __divdi3() for 'long long'
|
|
division on 32-bit arches.
|
|
- mutex_lock_nested() was introduced as part of the mutex
|
|
validator in 2.6.18, when it is unavailable it is safe to
|
|
fallback to using a plain mutex_lock().
|
|
- SLES specific API change to vfs_unlink() and vfs_rename() which
|
|
added a 'struct vfsmount *' argument. This was for something
|
|
called the linux-security-module, but it appears that it was
|
|
never adopted upstream.
|
|
- spl_device_create() correctly mapped to class_device_create()
|
|
for 2.6.13 to 2.6.17 based kernels, this is the preferred API.
|
|
- Prior to 2.6.17 there were no *_pgdat helper functions in
|
|
mm/mmzone.c. Instead for_each_zone() operated directly on
|
|
pgdat_list which may or may not have been exported depending on
|
|
how your kernel was compiled. A configure check was added to
|
|
determine if you have the helpers or not, and if the needed
|
|
symbols are exported. If they are not exported then they are
|
|
dynamically aquired at runtime by kallsyms_lookup_name().
|
|
|
|
* : Packaging changes for SLES10
|
|
- Properly honor --prefix in build system and rpm spec file.
|
|
- Add '--define require_kdir' to spec file to support building
|
|
rpms against kernel sources installed in non-default locations.
|
|
- Add '--define require_kobj' to spec file to support building
|
|
rpms against kernel object installed in non-default locations.
|
|
- Stop suppressing errors in autogen.sh script.
|
|
- Improved logic to detect missing kernel objects when they are
|
|
not located with the source. This is the common case for SLES
|
|
as well as in-tree chaos kernel builds and is done to simply
|
|
support for multiple arches.
|
|
- Moved spl-devel build products to /usr/src/spl-<version>, a
|
|
spl symlink is created to reference the last installed version.
|
|
- Allow checking for exported symbols in both Module.symvers
|
|
and Module.symvers. My stock SLES kernel ships an objects
|
|
directory with Module.symvers, yet produces a Module.symvers
|
|
in the local build directory.
|
|
|
|
* : Added powerpc64 support.
|
|
- Enable builds for powerpc64 ISA type.
|
|
- Add DIV_ROUND_UP and roundup macros if unavailable.
|
|
- Cast 64-bit values for %lld format string to (long long) to
|
|
quiet compile warning.
|
|
|
|
* module/splat/splat-ctl.c: Proper ioctl() 32/64-bit binary
|
|
compatibility. We need to ensure the ioctl data itself is always
|
|
packed the same for 32/64-bit binaries. Additionally, the correct
|
|
thing to do is encode this size in bytes as part of the command
|
|
using _IOC_SIZE().
|
|
|
|
* modules/spl/spl-kmem.c: Fixed a long standing bug in the debug
|
|
tracing. The tcd_for_each() macro expected a NULL to terminate
|
|
the trace_data[i] array but this was only ever true due to luck.
|
|
All trace_data[] iterators are now properly capped by TCD_TYPE_MAX.
|
|
|
|
* modules/spl/spl-kmem.c: To simplify debugging all symbols aquired
|
|
dynamically using spl_kallsyms_lookup_name() are initially poisoned
|
|
with SYMBOL_POISON.
|
|
|

|
|
|
|
* : Tag spl-0.4.3
|
|
|
|
* configure.ac, *Makefile.am: Build system update. This includes
|
|
resolving various build issues and adding support for the remaining
|
|
common build targets. Available targets now include:
|
|
|
|
- make all # Build everything
|
|
- make install # Install everything
|
|
- make clean # Clean up build products
|
|
- make distclean # Clean up everything
|
|
- make dist # Create package tarball
|
|
- make srpm # Create package source RPM
|
|
- make rpm # Create package binary RPMs
|
|
- make tags # Create ctags and etags for everything
|
|
|
|
Extra care was taken to ensure that the source RPMs are fully
|
|
rebuildable against Fedora/RHEL/Chaos kernels. To build binary
|
|
RPMs from the source RPM for your system simply run:
|
|
|
|
rpmbuild --rebuild spl-x.y.z-1.src.rpm
|
|
|
|
This will produce two binary RPMs with correct 'requires'
|
|
dependencies for your kernel. One will contain all zpl modules
|
|
and support utilities, the other is a devel package for compiling
|
|
additional kernel modules which are dependent on the spl.
|
|
|
|
spl-x.y.z-1_<kernel version>.x86_64.rpm
|
|
spl-devel-x.y.2-1_<kernel version>.x86_64.rpm
|
|
|
|
* : FC10 (linux-2.6.27.19) and i686 compatibility update. The
|
|
list of support platforms has been extended to include FC10
|
|
systems and x86 architectures. It should be noted that kernels
|
|
older the 2.6.27.19 should work but have not have not been tested.
|
|
|
|
* configure.ac: Fix build issue preventing spl_config.h from being
|
|
cleanly included by dependent packages.
|
|
|
|
* module/spl/spl-taskq.c: Fix taskq_wait() not waiting bug.
|
|
|
|
* module/spl/spl-xdr.c: Add XDR implementation provided by Ricardo
|
|
Correia from Sun.
|
|
|
|
* module/spl/spl-kmem.c: Linux VM integration cleanup.
|
|
|
|
* module/spl/spl-kmem.c: Slab cache improvements and fixes.
|
|
|
|
* modules/splat/*: Include additional SPLAT regression tests.
|
|
|
|
* : Various bug fixes are more clearly detailed in the git
|
|
commit logs. For a detailed summary of changes post version
|
|
0.4.2 check the git commit logs.

|
|
* : Tag spl-0.4.2
|
|
|
|
* module/spl/spl-kmem.c include/sys/kmem.h: Slab cache improvements:
|
|
- Implement kmem cache alignment.
|
|
- Implement slab ageing.
|
|
- Optimized slab packing algorithm.
|
|
- Fixed deadlock due to calling call kv_free() under the skc_lock.
|
|
- Added additional SPLAT test cases
|
|
- Performance optimizations
|
|
|
|
* module/spl/spl-kmem.c include/sys/kmem.h: Linux VM integration.
|
|
The Solaris global VM symbols minfree, desfree, lotsfree, needfree,
|
|
swapfs_minfree, swapfs_reserve, availrmem, freemem, and physmem are
|
|
now available and loosely integrating with the Linux VM. Some
|
|
tuning will undoubtably be needed and these tunables are available
|
|
in /proc/sys/kernel/spl/vm/* for this very reason.
|
|
|
|
* config/spl-build.m4: New configure checks needed when building
|
|
against 2.6.27+ kernels. More work is needed here.
|
|
|
|
* : Minor cleanup see the 'git log' for full details.
|
|

|
|
* : Tag spl-0.4.1
|
|
|
|
* : Implement ksid_*, ddi_strto*, and system taskq functionality.
|
|
In addition, several other small Solaris compatibility changes
|
|
were made, see the 'git log' for full details.

2008-11-05 Jim Garlick <garlick@llnl.gov>
|
|
|
|
* : Add autogen.sh products.
|
|
|
|
* configure.ac : Use AC_CONFIG_AUX_DIR to put autograph products
|
|
in ./auotconf.
|
|
|
|
* autogen.sh : Use --copy to avoid symlinks, remove error
|
|
redirection, run aclocal before libtoolize.
|
|
|
|
2008-11-13 Brian Behlendorf <behlendorf1@llnl.gov>
|
|
|
|
* include/sys/sunddi.h, modules/spl/spl-module.c : Removed default
|
|
udev support from sunddi implementation because it uses GPL-only
|
|
symbols. This support is optionally available for SPL consumers
|
|
if they define HAVE_GPL_ONLY_SYMBOLS and license their module as
|
|
GPL using the MODULE_LICENSE("GPL") macro.

|
* : Tag spl-0.3.3
|
|
|
|
* : modules/sys/kmem-slab.c : Refined SPL slab to include
|
|
per-cpu caches, removed internal hash, other general
|
|
performance improvements. Much work remain but it's pretty
|
|
good for an initial implementation.
|
|
|
|
2008-06-13 Brian Behlendorf <behlendorf1@llnl.gov>
|
|
|
|
* : modules/sys/kmem-slab.c : Re-implemented the slab to no
|
|
longer be based on the linux slab but to be it's own complete
|
|
implementation. The new slab behaves much more like the
|
|
Solaris slab than the Linux slab.
|
|

2008-06-04 Brian Behlendorf <behlendorf1@llnl.gov>
|
|
|
|
* : Tag spl-0.3.2
|
|
|
|
* : Extensive improvements to the build system to detect kernel
|
|
API changes so we can flexibly build with a wider range of kernel
|
|
versions. The code has now been testing with the 2.6.18-32chaos
|
|
and 2.6.25.3-18.fc9 kernels, however we should also be compatible
|
|
with other kernels in the range of 2.6.18-2.6.25.
|
|
|
|
2008-05-25 Brian Behlendorf <behlendorf1@llnl.gov>
|
|
|
|
* configure.ac, autoconf/* : Initial pass at resolving
|
|
API changes introduced by kernels newer than 2.6.18.
|
|
|
|
2008-05-21 Brian Behlendorf <behlendorf1@llnl.gov>
|
|
|
|
* : Tag spl-0.3.1
|
|
|
|
* : License headers including URCL added for release.
|
|
|

2008-05-21 Brian Behlendorf <behlendorf1@llnl.gov>
|
|
|
|
* : Tag spl-0.3.0
|
|
|
|
* configure.ac: Improved autotools support.
|
|
|
|
2008-04-26 Brian Behlendorf <behlendorf1@llnl.gov>
|
|
|
|
* include/sys/mutex.h : Implemented a close approximation
|
|
of adaptive mutexes. These changes however required me to
|
|
export a new symbol from the kernel proper 'task_curr()'
|
|
which means we are now dependant on a patched kernel.
|
|
|
|
2008-04-24 Brian Behlendorf <behlendorf1@llnl.gov>
|
|
|
|
* : Tag spl-0.2.1
|
|
|
|
* modules/spl/spl-proc.c : Add /proc/sys/spl/version.
|
|
|
|
2008-04-24 Herb Wartens <wartens2@llnl.gov>
|
|
|
|
* include/sys/kmem.h : Make sure that when calling __vmem_alloc
|
|
that we do not have __GFP_ZERO set. Once the memory is allocated
|
|
then zero out the memory if __GFP_ZERO is passed to
|
|
__vmem_alloc.
|
|
|
|
2008-04-16 Herb Wartens <wartens2@llnl.gov>
|
|
|
|
* modules/spl/spl-kmem.c : Make sure to disable interrupts
|
|
when necessary to avoid deadlocks. We were seeing the deadlock
|
|
when calling kmem_cache_generic_constructor() and then an interrupt
|
|
forced us to end up calling kmem_cache_generic_destructor()
|
|
which caused our deadlock.
|
|
|
|
2008-02-26 Brian Behlendorf <behlendorf1@llnl.gov>
|
|
|
|
: Initial commit of the solaris porting layer (spl). Included
|
|
in addition to the source is an initial autoconf / configure
|
|
style build system.
