[PATCH v1 0/4] Add uprobes support for LoongArch
From: Tiezhu Yang
Date: Wed Apr 12 2023 - 06:05:27 EST
v1:
-- Split the RFC patch #2 into two patches
-- Use larch_insn_gen_break() to generate break insns
for kprobes and uprobes
-- Pass around instruction word instead of union for
insns_not_supported(), insns_need_simulation() and
arch_simulate_insn() to avoid type conversion for callers
-- Add a simple test case for uprobes in the commit message
Tiezhu Yang (4):

LoongArch: Add larch_insn_gen_break() to generate break insns
