Hello everyone, I have pushed into GIT the newly restructured X86 code. There were lots of changes and the code in arch/x86/perfmon/perfmon.c looks a lot better now. There is now a clear separation between x86 common and PMU-specific code. All the Pentium 4, SMT, IBS, PEBS specific code now lives in the corresponding PMU description modules.
All of this was possible by using a set of callbacks which act as override when they are defined. The generic code provides a default implementation for an action but each module can decide to have it own version because it needs to do additional operations or it can take certain shortcuts. There are 3 mandatory callbacks, the others are optional. Once Markus Metzger's ds.h interface is fully integrated into the mainline kernel, I will switch over to his interface for support PEBS. This will remove some more code from perfmon and the PMU description modules. Some generic <-> arch specific callback were removed and others had their interfaces simplified, thus the patch touches more than just x86. I would appreciate if you could test this new code on your x86 hardware. It does work on Intel Core, and P6 machines. It needs more testing on AMD machines. To use this new code, simply pull from the GIT tree. Report any problem to me and the list. Thanks. ------------------------------------------------------------------------- This SF.net email is sponsored by the 2008 JavaOne(SM) Conference Register now and save $200.
