| 2020-05-13 | csky: Fixup perf probe -x hungup | Guo Ren | |
| case: # perf probe -x /lib/libc-2.28.9000.so memcpy # perf record -e probe_libc:memcpy -aR sleep 1 System hangup and cpu get in trap_c loop, because our hardware singlestep state could still get interrupt signal. When we get in uprobe_xol singlestep slot, we should disable irq in pt_regs->psr. And is_swbp_insn() need a csky arch implementation with a low 16bit mask.
