I have a Pentium 4 box running Fedora Core 3, which I installed oprofile 0.9.1 on. 'opcontrol -l' says that only timer interrupt mode is supported. Prior to installing oprofile I rebuilt the kernel to include in the config: CONFIG_PROFILING=y CONFIG_OPROFILE=m With the running kernel with profiling enabled, I built and installed oprofile. According to the manual, I should be able to access various events through the P4, including cache misses. So why is just timer interrupt mode supported? I should not that my Dell Inspiron 5000e laptop w/ Pentium 3 also running FC3 has the same problem. Here is the /proc/cpuinfo output: processor : 0 vendor_id : GenuineIntel cpu family : 15 model : 2 model name : Intel(R) Pentium(R) 4 CPU 2.00GHz stepping : 4 cpu MHz : 2009.692 cache size : 512 KB fdiv_bug : no hlt_bug : no f00f_bug : no coma_bug : no fpu : yes fpu_exception : yes cpuid level : 2 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 apic mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm bogomips : 3964.92 --john |
