At this point, LTT supports 6 architectures: i386, PPC, S/390, ARM, SuperH, and MIPS. Here's what's in 0.9.6pre1: - Lockless logging implementation a-la K42 by Tom Zanussi (IBM). This was added to the 2.5.x patch series only. - ARM port by Frank Rowand (MontaVista). - MIPS port update/cleanup by Frank Rowand (MontaVista). - Autotools update by Andrea Cisternino (ST Micro) and Frank Rowand (MontaVista) - Added RTAI install script by Klaas Gadeyne to Examples/ directory. - Added arch/mips/timer.c instrumentation by Bino Mathew (Wipro). - Fixes for keeping track of event details by Andreas Heppel (Sysgo). - Fixes for SMP trace analysis by Frank Rowand (MontaVista). - Moved max limit of IRQ to 256 for XScale by Frank Rowand (MontaVista). The lockless logging feature is very important because LTT can now trace a system without using any spinlocks or IRQ disabling whatsoever. Though this feature is currently only in the 2.5.35 patch included with LTT, it will be part of all patches for kernels past 2.5.35. At this time, preliminary testing of the 2.5.35 patch included in 0.9.6pre1 has shown some minor issues which will result in lockups. These issues will be addressed in a patch I will soon be releasing for 2.5.36. This is a development release, so the usual warnings apply. You will find 0.9.6pre1 here: http://opersys.com/ftp/pub/LTT/ LTT's web site is here: http://www.opersys.com/LTT Karim =================================================== Karim Yaghmour karim@opersys.com Embedded and Real-Time Linux Expert =================================================== - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
