last mainline attempt was over a year ago |
axfs |
? |
? |
? |
LogFS |
Not mainlined yet. In active development with patches submitted to LKML |
? |
Reported to still be not-ready-for-prime-time; could offer significant memory gains for embedded flash-based systems |
LTTng |
core not mainlined (what about markers??) |
? |
LTTng instrumentation bits were changed to use markers, in early 2007 |
SystemTap (and Kprobes) for non-i386 arches |
no embedded arch support mainlined yet |
? |
KProbes ports for ARM, MIPS and PPC32 were reported on at ELC 2007, SystemTap for SH was demo'ed at ELC 2007 |
pagemap instrumentation |
currently in -mm, targetted for 2.6.23? |
July 2007 |
Matt Mackall was fixing a lock contention bug (as of July 2007) |
KFT (Kernel Function Trace) |
not mainlined - broken on ARM (with gcc > 4.x), PPC64 has problems (reports parent funcs of inlines) |
last published external patches for 2.6.21 |
working to transfer maintainership of this from Tim Bird to Nicholas McGuire |
printk-times (arch support) |
fully mainlined? |
April, 2005 |
Some arches had problems with accessing the clock too early in the kernel bootup sequence, but a new setup routine defers turning on the timestamping until after timekeeping is initialized |
RT-preempt |
some parts mainlined (last part was high res. timers in 2.6.21) |
2.6.21? |
Next target is to integrate threaded interrupts in 2.6.23?? |
App Armour |
not mainlined |
