Futher testing on my powerpc system revealed that the powerpc
specific atomic implemetation was flawed. Rather than spending
a lot of time correctly reimplementing it in assembly I have
reworked it in to a 100% generic version. The generic version
will not perform well but it does provide correct sematics. It
will be used only when there is no architecture specific version
available. These changes do not impact x86_64 and x86 which have
have correct native implementations.
These changes bring the zfs-0.4.4 tree in to compliance with
the spl-0.4.4 packaging changes. The bottom line is 2 source
rpms and 4 binary rpms will now be generated when creating
packages there will be:
zfs-<version>.src.rpm
- Fully rebuildable source rpm for libzfs and utils.
zfs-modules-<version>.src.rpm
- Fully rebuildable source rpm for kernel modules.
zfs-<version>.<arch>.rpm
- Binary rpm for libzfs and utils. The utils in this package are
compatible with all zfs-module rpms of the same version.
zfs-devel-<version>.<arch>.rpm
- Binary rpm containing headers for building against libzfs libraries.
zfs-modules-<verion>-<kernel>.arch.rpm
- Binary rpm containing the kernel modules for a specific kernel build.
The package name contains the kernel version and you should have one
of these packages installed to match every kernel on your system.
zfs-modules-devel-<verion>-<kernel>.arch.rpm
- Binary rpm containing development header and module symbols needed
for building additional kernel modules which are dependent on the
zfs module stack.
Expect minor interations on these changes as I validate they work
properly on CHAOS, RHEL, Fedora, and SLES style distros.
- Add 64-bit user space atomic support obtained from an old version
of OpenSolaris which supported ppc. They are not all 100% fully
implemented by they are a good first step.
- Add powerpc ISA type.
- Strip out unused ISA defines to prevent any confusion.
Depending on your x86 architecture $target_cpu can evaluate to
any of the following (i386|i486|i586|i686). Since our local asm
uses only i386 instructions sed is used to map all of these to
i386 and sets $target_arch. Other arch's are not impacted.
An update to the build system to properly support all commonly
used Makefile targets these 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 zfs-x.y.z-1.src.rpm
This will produce two binary RPMs with correct 'requires'
dependencies for your kernel. One will contain all zfs modules
and support utilities, the other is a devel package for compiling
additional kernel modules which are dependant on the zfs.
zfs-x.y.z-1_<kernel version>.x86_64.rpm
zfs-devel-x.y.2-1_<kernel version>.x86_64.rpm
of the kernel specific build info in to config/kernel,
likewise and user specific build flags should go in
config/user. This seems like a reasonable way to go.
