Stupid(?) question... I'm trying to catch a bug and am thinking that the bph command is just the ticket.
So I set one and get a response: kdb> bph 0xcf33c554 DATAR 4 Forced Data Access BP #0 at 0xcf33c554 is enabled in dr0 for 4 bytes on cpu 0 kdb> but the breakpoint never gets hit :-( The address above is the file member of a task struct, so I'd think I could induce a look... I realize that the processor has to support these breakpoints and I'm wondering now whether my processor simply won't do what I want or I'm just a dumbass that hasn't configured the kernel correctly... My cpuinfo: [root@scum /mnt]# cat /proc/cpuinfo processor : 0 vendor_id : GenuineIntel cpu family : 6 model : 8 model name : Pentium III (Coppermine) stepping : 3 cpu MHz : 498.674 cache size : 256 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 sep mtrr pge mca cmov pat pse36 mmx fxsr sse bogomips : 996.14 Thanks for any hints, Georg
