This patch set will help user to instrument a watchpoint with all possible byte select options. Changes since v1: Introduced a new patch 3/5 where it takes care of the situation when HW does not report a watchpoint hit with the address that matches one of the watchpoints set. Added corresponding test case to test that functionality. Pavel Labath (1): arm64: hw_breakpoint: Handle inexact watchpoint addresses Pratyush Anand (4): hw_breakpoint: Allow watchpoint of length 3,5,6 and 7 arm64: Allow hw watchpoint at varied offset from base address arm64: Allow hw watchpoint of length 3,5,6 and 7 selftests: arm64: add test for unaligned/inexact watchpoint handling arch/arm64/include/asm/hw_breakpoint.h | 6 +- arch/arm64/kernel/hw_breakpoint.c | 149 +++++++++---- arch/arm64/kernel/ptrace.c | 5 +- include/uapi/linux/hw_breakpoint.h | 4 + tools/include/uapi/linux/hw_breakpoint.h | 4 + tools/testing/selftests/breakpoints/Makefile | 5 +- .../selftests/breakpoints/breakpoint_test_arm64.c | 236 +++++++++++++++++++++ 7 files changed, 366 insertions(+), 43 deletions(-) create mode 100644 tools/testing/selftests/breakpoints/breakpoint_test_arm64.c -- 2.7.4
