From a94d308513bdb2b926b45c11d7ce7fac6d6ca865 Mon Sep 17 00:00:00 2001 From: Anton Blanchard Date: Sat, 10 Sep 2005 16:01:10 +1000 Subject: [PATCH] [PATCH] ppc64: Add definitions for new PTRACE calls - Add PTRACE_GET_DEBUGREG/PTRACE_SET_DEBUGREG. The definition is as follows: /* * Get or set a debug register. The first 16 are DABR registers and the * second 16 are IABR registers. */ #define PTRACE_GET_DEBUGREG 25 #define PTRACE_SET_DEBUGREG 26 DABR == data breakpoint and IABR = instruction breakpoint in IBM speak. We could split out the IABR into 2 more ptrace calls but I figured there was no need and 16 DABR registers should be more than enough (POWER4/POWER5 have one). - Add 2 new SIGTRAP si_codes: TRAP_HWBKPT and TRAP_BRANCH. I couldnt find any standards on either of these so I copied what ia64 is doing. Again this might be better placed in include/asm-generic/siginfo.h Signed-off-by: Anton Blanchard Signed-off-by: Paul Mackerras --- include/asm-powerpc/siginfo.h | 8 ++++++++ include/asm-ppc/ptrace.h | 7 +++++++ include/asm-ppc64/ptrace.h | 7 +++++++ 3 files changed, 22 insertions(+) diff --git a/include/asm-powerpc/siginfo.h b/include/asm-powerpc/siginfo.h index 538ea8e..12f1bce 100644 --- a/include/asm-powerpc/siginfo.h +++ b/include/asm-powerpc/siginfo.h @@ -15,4 +15,12 @@ #include +/* + * SIGTRAP si_codes + */ +#define TRAP_BRANCH (__SI_FAULT|3) /* process taken branch trap */ +#define TRAP_HWBKPT (__SI_FAULT|4) /* hardware breakpoint or watchpoint */ +#undef NSIGTRAP +#define NSIGTRAP 4 + #endif /* _ASM_POWERPC_SIGINFO_H */ diff --git a/include/asm-ppc/ptrace.h b/include/asm-ppc/ptrace.h index 9d4e4ea..7043c16 100644 --- a/include/asm-ppc/ptrace.h +++ b/include/asm-ppc/ptrace.h @@ -142,4 +142,11 @@ do { \ #define PTRACE_GETEVRREGS 20 #define PTRACE_SETEVRREGS 21 +/* + * Get or set a debug register.
