hi，i had add the bench.c and its related codes into linux，but there are something wrong when compilation： LD vmlinux.o MODPOST vmlinux.symvers MODINFO modules.builtin.modinfo GEN modules.builtin LD .tmp_vmlinux.kallsyms1 aarch64-v01c01-linux-musl-ld: warning: -z norelro ignored aarch64-v01c01-linux-musl-ld: Unexpected GOT/PLT entries detected! aarch64-v01c01-linux-musl-ld: Unexpected run-time procedure linkages detected! aarch64-v01c01-linux-musl-ld: drivers/tee/optee/bench.o: in function optee_bm_timestamp': bench.c:(.text+0x14c): undefined reference to__aarch64_ldadd8_acq_rel' Makefile:1185: recipe for target 'vmlinux' failed

i dont know how to fix it

i had tried to add -march=armv8-a to CFLAGS and -latomic to LDFALGS， but it make no sense

this issue had been solved， but when i enable CFG_TEE_BENCHMARK in linux optee_os optee_client，but the benchmark always have error： [Benchmark] INFO: 1. Opening Benchmark Static TA... [Benchmark] INFO: 2. Allocating per-core buffers, cores detected = 2 E/TC:? 00 get_rpc_alloc_res:645 RPC allocation failed. Non-secure world result: ret=0xffff0006 ret_origin=0x2 E/TC:? 00 alloc_benchmark_buffer:72 Benchmark: can't create mobj for timestamp buffer [Benchmark] ERROR: TEEC_InvokeCommand: 0xffff000c

I'm sorry, but the benchmark isn't maintained any longer. It should hopefully not be too hard to get it to work again if someone is willing to maintain it.
