  • c49b6ecf0   sh: Fix ptrace fpu state initialisation ... Browse Code »

    Commit 0ea820cf introduced the PTRACE_GETFPREGS/SETFPREGS cmds,
    but gdb-server still accesses the FPU state using the
    PTRACE_PEEKUSR/POKEUSR commands. In this case, xstate was not
    initialised.

  • 9e1cb2061   ptrace: cleanup arch_ptrace() on sh ... Browse Code »

    Remove unnecessary castings and get rid of dummy pointer in favor of
    offsetof() macro in ptrace_32.c. Also use temporary variables and
    break long lines in order to improve readability.

    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.

    The only BKL user in arch/sh protects a single bit,
    so we can trivially replace it with test_and_set_bit.

  • eaaaeef39   sh: Add kprobe-based event tracer. ... Browse Code »

    This follows the x86/ppc changes for kprobe-based event tracing on sh.
    While kprobes is only supported on 32-bit sh, we provide the API for
    HAVE_REGS_AND_STACK_ACCESS_API for both 32 and 64-bit.

  • 4b505db9c   sh64: fix tracing of signals. ... Browse Code »

    This follows the parisc change to ensure that tracehook_signal_handler()
    is aware of when we are single-stepping in order to ptrace_notify()
    appropriately. While this was implemented for 32-bit SH, sh64 neglected
    to make use of TIF_SINGLESTEP when it was folded in with the 32-bit code,
    resulting in ptrace_notify() never being called.

    As sh64 uses all of the other abstractions already, this simply plugs in
    the thread flag in the appropriate enable/disable paths and fixes up the
    tracehook notification accordingly. With this in place, sh64 is brought
    in line with what 32-bit is already doing.

  • a74f7e041   sh: Wire up HAVE_SYSCALL_TRACEPOINTS. ... Browse Code »

    This is necessary to get ftrace syscall tracing working again.. a fairly
    trivial and mechanical change. The one benefit is that this can also be
    enabled on sh64, despite not having its own ftrace port.
