This patch introduces the generic Hardware Breakpoint interfaces for both user and kernel space requests. This core Api handles the hardware breakpoints through new helpers. It handles the user-space breakpoints and kernel breakpoints in front of arch implementation. One can choose kernel wide breakpoints using the following helpers and passing them a generic struct hw_breakpoint: - register_kernel_hw_breakpoint() - unregister_kernel_hw_breakpoint() - modify_kernel_hw_breakpoint() On the other side, you can choose per task breakpoints. - register_user_hw_breakpoint() - unregister_user_hw_breakpoint() - modify_user_hw_breakpoint() [ fweisbec@gmail.com: fix conflict against perfcounter ] Original-patch-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: K.Prasad <prasad@linux.vnet.ibm.com> Reviewed-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Frederic Weisbecker <fweisbec@gmail.com> |
