This build system is re-written from scratch except some code snips:
- Compatible with systems that were using TK kernel.
- Compatible with RHEL-like systems.
- Resolved tons of hacks and workaround from TK/RHEL. (leftovers are
marked as TODO)
- All RPM builtin debuginfo utilities are well leveraged (buildid
re-generate, dwarf compression, etc...)
- For bpftool and BTF info extracting, this package will try self-bootstrap
and don't depend on host kernel during build time.
- Well commented, and targeted for maximum compatibility.
- Integrated config management system.
- Integrated with version management system.
- Provides many utils.
- Cross-build and cross packaging, also cross kABI checking/updating.
- ...
To start, just run:
make dist-rpm
And for help, just run:
make dist-help
It will build following packages:
kernel
Main meta package, empty, depend on kernel-core and kernel-modules
kernel-core
The package contains kernel image and core modules, able to boot
all machines, all kinds of VMs etc.
kernel-modules
Contains extra modules and drivers, most modules that are not
required for VMs and common hardware should go into this pacakge.
kernel-devel
Devel files for building custom kernel modules.
kernel-headers
Kernel headers.
perf
python3-perf
Userspace tool perf.
kernel-tools
kernel-tools-libs
kernel-tools-libs-devel
Userspace tools like cpupower, slabinfo, etc...
bpftool
bpftool
kernel-debuginfo
kernel-debuginfo-common
perf-debuginfo
python3-perf-debuginfo
kernel-tools-debuginfo
bpftool-debuginfo
All kinds of debuginfo
