It utilizedsoftware breakpoint and single step debug exceptions, instructionssimulation on csky.We use USR_BKPT replace origin instruction, and the kprobe handlerprepares an excutable memory slot for out-of-line execution with acopy of the original instruction being probed. Most of instructionscould be executed by single-step, but some instructions need originpc value to execute and we need software simulate these instructions.Signed-off-by: Guo Ren <guoren@linux.alibaba.com>Cc: Arnd Bergmann <arnd@arndb.de>Cc: Steven Rostedt (VMware) <rostedt@goodmis.org> List of files: /linux-6.15/arch/csky/kernel/probes/Makefile Wed, 01 Apr 2020 01:17:02 +0000 Guo Ren <guoren@linux.alibaba.com>
