2010-10-28T01:03:10Z

use new 'datap' variable in order to remove unnecessary castings. Signed-off-by: Namhyung Kim Cc: Russell King Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

ptrace: change signature of arch_ptrace()

2010-10-28T01:03:10Z

Fix up the arguments to arch_ptrace() to take account of the fact that @addr and @data are now unsigned long rather than long as of a preceding patch in this series.

ARM: 6357/1: hw-breakpoint: add new ptrace requests for hw-breakpoint interaction

2010-09-08T09:05:00Z

For debuggers to take advantage of the hw-breakpoint framework in the kernel, it is necessary to expose the API calls via a ptrace interface. This patch exposes the hardware breakpoints framework as a collection of virtual registers, accesible using PTRACE_SETHBPREGS and PTRACE_GETHBPREGS requests. The breakpoints are stored in the debug_info struct of the running thread. Cc: Frederic Weisbecker Cc: S. Karthikeyan Signed-off-by: Will Deacon Signed-off-by: Russell King

ARM: 6199/1: Add kprobe-based event tracer

2010-07-09T13:41:34Z

This patch enables the HAVE_REGS_AND_STACK_ACCESS_API option for ARM which is required by the kprobe events tracer. Code based on the PowerPC port. Cc: Jean Pihet Tested-by: Jamie Iles Signed-off-by: Will Deacon Signed-off-by: Russell King

arm: use generic ptrace_resume code

2010-03-12T23:52:38Z

Use the generic ptrace_resume code for PTRACE_SYSCALL, PTRACE_CONT, PTRACE_KILL and PTRACE_SINGLESTEP. This implies defining arch_has_single_step in and implementing the user_enable_single_step and user_disable_single_step functions, which also causes the breakpoint information to be cleared on fork, which could be considered a bug fix. Also the TIF_SYSCALL_TRACE thread flag is now cleared on PTRACE_KILL which it previously wasn't and the single stepping disable only happens if the tracee process isn't a zombie yet, which is consistent with all architectures using the modern ptrace code.

ARM: vfp ptrace: no point flushing hw context for PTRACE_GETVFPREGS

2010-02-15T21:39:53Z

If we're only reading the VFP context via the ptrace call, there's no need to invalidate the hardware context - we only need to do that on PTRACE_SETVFPREGS. This allows more efficient monitoring of a traced task. Signed-off-by: Russell King

ARM: ptrace: get rid of PTRACE_{PEEK,POKE}{TEXT,DATA}

2010-02-15T21:39:52Z

The generic ptrace_request() handles these for us, so there's no need to duplicate them in arch code. Signed-off-by: Russell King

ARM: 5912/1: Define a 32-bit Thumb-2 breakpoint instruction

2010-02-15T21:39:52Z

Recognize 0xf7f0 0xa000 as a 32-bit breakpoint instruction for Thumb-2. Signed-off-by: Daniel Jacobowitz Signed-off-by: Russell King

nommu: ptrace support

2009-07-24T11:34:58Z

The patch below adds ARM ptrace functions to get the process load address. This is required for useful userspace debugging on mmuless systems. These values are obtained by reading magic offsets with PTRACE_PEEKUSR, as on other nommu targets. I picked arbitrary large values for the offsets. Signed-off-by: Paul Brook

[ARM] 5387/1: Add ptrace VFP support on ARM

2009-02-12T10:59:43Z

This patch adds ptrace support for setting and getting the VFP registers using PTRACE_SETVFPREGS and PTRACE_GETVFPREGS. The user_vfp structure defined in asm/user.h contains 32 double registers (to cover VFPv3 and Neon hardware) and the FPSCR register.
