Hi;
This is the compatibility combination that I am using:
0.8.82
0.9.0
0.37
obsolete
0.29
0.34
0.8
2.6.20
ARM, MIPS32/64, powerpc32, powerpc64, ppc, i386, x86_64
Introduces the LTT serialization library. Cuts the kernel patch size
from 2M to 500k. Deprecates genevent for kernel instrumentation, but
keeps backward compatibility with genevent generated code (still used
for user space tracing). Slightly longer execution time at
instrumentation site (270ns vs 200ns for 4 bytes write on P4 3GHz), but
the global advantage of using less memory, and therefore less cache,
should overweight this cost in cycles. Note : In this version, the
ltt-probe-* kernel modules and the XML definitions must be kept in sync
by hand, otherwise, LTTV will detect a size mismatch between the kernel
trace and the expected event size..
arm, i686, ia64, m68k, mips, mipsel, x86_64, powerpc 405, powerpc64,
s390, sparc, sparc64.
alpha, arm26, avr32, cris, frv, h8300, m32r, m68knommu, parisc, sh,
sh64, um, v850, xtensa
Could someone please provide more details about the note given?
Note : In this version, the ltt-probe-* kernel modules and the XML
definitions must be kept in sync by hand, otherwise, LTTV will detect a
size mismatch between the kernel trace and the expected event size..
Which LTTng-0.9.0/LTTV files to look out for to maintain the
sync?
Thanks.
Regards,
KH

Which versino of LTTng patch have you used exactly ?
Did you follow this compatibility list ?
