Hi Heiko/Frederic, Please find the latest set of patches that introduces s390 specific implementation for perf-events based hardware breakpoint interfaces for review. Change in v5: - Use exclude_kernel attribute set to decide whether to install wide breakpoint in kernel or not. This flag will be used by ptrace breakpoint. - Removed 'info->name' field as Name to address resolving is done in generic code. - Select CONFIG_HAVE_MIXED_BREAKPOINTS_REGS as s390 uses same register for instruction as well as data breakpoint. - Re-based the patches on commit d67f088e084755bdceb4f15bc6e05e309db1eea7 of -tip perf/core Change in v4: - Introduced a kernel per tracing flag in lowcore structure for each cpu instead of global. - Handled a race condition with interrupts/preemption while looking for PER event in hw_breakpoint_handler() routine. Change in v3: - Merged first two patches of v1 patchset. - Introduced second patch that implements kernel part PER tracing. The patch set has been tested with ksym_tracer and watchpoints over GDB+ptrace and works fine.
