hujun5 ddf1410312 sched/signal: There is no need to use sched_[un]lock ... purpose: 1 sched_lock is very time-consuming, and reducing its invocations can improve performance. 2 sched_lock is prone to misuse, and narrowing its scope of use is to prevent people from referencing incorrect code and using it test: We can use qemu for testing. compiling make distclean -j20; ./tools/configure.sh -l qemu-armv8a:nsh_smp ;make -j20 running qemu-system-aarch64 -cpu cortex-a53 -smp 4 -nographic -machine virt,virtualization=on,gic-version=3 -net none -chardev stdio,id=con,mux=on -serial chardev:con -mon chardev=con,mode=readline -kernel ./nuttx We have also tested this patch on other ARM hardware platforms.
