ipc_bios - Builds all targets within the IPC component
ipc_clean - Cleans all targets within the IPC component
Example Targets:
ipc_examples - Builds IPC examples
ipc_examples_clean - Cleans IPC examples
NOTE: Instructions for rebuilding all other components
installed with Processor SDK can be found in each
component's sub-directory
可以看到，rtos-sdk里面仅编译了pdk、ipc_bios，那么
1、sys/bios怎么编译呢？还有其他一些dsplib、ndk…这些都没见编译？
2、ipc放在linux上执行时，linux内核要打补丁？我看到的是如下结构，补丁是给内核3.0.8用的？我当前linux内核是4.19.59，还需要打这个补丁吗，如果需要的话，版本不一样可以吗？
