Hi,
Is it possible to build the lttng modules againt Centos Stream 9 kernels? I see
these warnings at the top when attempting to compile:
make[1]: Entering directory '/usr/src/kernels/5.14.0-452.el9.x86_64'
/home/tmp/git/lttng-modules/src/probes/Kbuild:28: File ./mm/slab.h not found.
Probe "kmem" is disabled. Use full kernel source tree to enable it.
/home/tmp/git/lttng-modules/src/probes/Kbuild:79: File ./arch/x86/kvm/lapic.h
not found. Probe "kvm" x86-specific is disabled. Use full kernel source tree to
enable it.
/home/tmp/git/lttng-modules/src/probes/Kbuild:181: Files ./mm/internal.h not
found. Probe "compaction" is disabled. Use full kernel source tree to enable
it.
/home/tmp/git/lttng-modules/src/probes/Kbuild:190: Files ./fs/ext4/*.h not
found. Probe "ext4" is disabled. Use full kernel source tree to enable it.
/home/tmp/git/lttng-modules/src/probes/Kbuild:213: File
./drivers/base/regmap/trace.h not found. Probe "regmap" is disabled. Use full
kernel source tree to enable it.
I tried with module versions 2.12.17 and 2.13.13 against the kernel
5.14.0-452.el9.x86_64 and I obtain this error:
/home/tmp/git/lttng-modules/src/probes/../../include/lttng/tracepoint-event-impl.h:133:6:
error: conflicting types for 'trace_sched_stat_runtime'; have 'void(struct
task_struct *, u64, u64)' {aka 'void(struct task_struct *, long long unsigned
int, long long unsigned int)'}
Any help would be greatly appreciated.
