Remove arch-specific show_mem() in favor of the generic version. This also removes the following redundant information display: - free pages, printed by show_free_areas() - pages in swapcache, printed by show_swap_cache_info() where show_mem() calls show_free_areas(), which calls show_swap_cache_info().

And show_mem() does now actually print something on configurations with multiple nodes. Signed-off-by:

This implements a platform-independent version of show_mem(). Signed-off-by:
-
Johannes Weiner authored
Every arch implements its own show_mem() function. Most of them share quite some code, some of them are completely identical. This series implements a generic version of this function and migrates almost all architectures to it. This patch: Most show_mem() implementations calculate the amount of pages within the swapcache every time. Move the output to a more appropriate place and use the anyway available total_swapcache_pages variable. Signed-off-by:

This adds /proc/PID/syscall and /proc/PID/task/TID/syscall magic files. These use task_current_syscall() to show the task's current system call number and argument registers, stack pointer and PC. For a task blocked but not in a syscall, the file shows "-1" in place of the syscall number, followed by only the SP and PC. For a task that's not blocked, it shows "running". Signed-off-by:

This adds the new function task_current_syscall() on machines where the asm/syscall.h interface is supported (CONFIG_HAVE_ARCH_TRACEHOOK). It's exported for modules to use in the future. This function safely samples the state of a blocked thread to collect what system call it is blocked in, and the six system call argument registers. Signed-off-by:

This extends wait_task_inactive() with a new argument so it can be used in a "soft" mode where it will check for the task changing state unexpectedly and back off. There is no change to existing callers. This lays the groundwork to allow robust, noninvasive tracing that can try to sample a blocked thread but back off safely if it wakes up. Signed-off-by:

This adds the generic HAVE_ARCH_TRACEHOOK kconfig item. Each arch should add to some Kconfig file: select HAVE_ARCH_TRACEHOOK if the arch code uses all the latest hooks to enable newfangled tracing and debugging code. The comment in arch/Kconfig lists all the prerequisite arch support. When all these are available, setting HAVE_ARCH_TRACEHOOK will allow enabling any new features that depend on the modern arch interfaces. Signed-off-by:

This adds asm-generic/syscall.h, which documents what a real asm-ARCH/syscall.h file should define. This is not used yet, but will provide all the machine-dependent details of examining a user system call about to begin, in progress, or just ended. Each arch should add an asm-ARCH/syscall.h that defines all the entry points documented in asm-generic/syscall.h, as short inlines if possible. This lets us write new tracing code that understands user system call registers, without any new arch-specific work. Signed-off-by:

This adds tracehook.h inlines to enable a new arch feature in support of user debugging/tracing. This is not used yet, but it lays the groundwork for a debugger to be able to wrangle a task that's possibly running, without interrupting its syscalls in progress. Each arch should define TIF_NOTIFY_RESUME, and in their entry.S code treat it much like TIF_SIGPENDING. That is, it causes you to take the slow path when returning to user mode, where you get the full user-mode state accessible as for signal handling or ptrace. The arch code should check TIF_NOTIFY_RESUME after handling TIF_SIGPENDING. When it's set, clear it and then call tracehook_notify_resume(). In future, tracing code will call set_notify_resume() when it wants to get a callback in tracehook_notify_resume(). Signed-off-by:

Roland McGrath authored
This defines a new hook tracehook_force_sigpending() that lets tracing code decide to force TIF_SIGPENDING on in recalc_sigpending(). This is not used yet, so it compiles away to nothing for now. It lays the groundwork for new tracing code that can interrupt a task synthetically without actually sending a signal. Signed-off-by:

This moves the ptrace logic in task death (exit_notify) into tracehook.h inlines. Some code is rearranged slightly to make things nicer. There is no change, only cleanup. There is one hook called with the tasklist_lock write-locked, as ptrace needs. There is also a new hook called after exit_state changes and without locks. This is a better place for tracing work to be in the future, since it doesn't delay the whole system with locking. Signed-off-by:

This defines the tracehook_notify_jctl() hook to formalize the ptrace effects on the job control notifications. There is no change, only cleanup. Signed-off-by:

Roland McGrath authored
This defines the tracehook_get_signal() hook to allow tracing code to slip in before normal signal dequeuing. This lays the groundwork for new tracing features that can inject synthetic signals outside the normal queue or control the disposition of delivered signals. The calling convention lets tracehook_get_signal() decide both exactly what will happen and what signal number to report in the handler/exit. Signed-off-by:
