Hi,

This function, and many others, is generated by a tool called the 'bitfield generator' in tools/bitfield_gen.py It takes as input files ending in .bf, and can produce both C code and proofs said code. If you were to look in include/arch/arm/arch/object/structures.bf you would find a block structure called 'thread_state' with a field member called 'tcbQueued'. The bitfield generator takes this data structure description and generates all the relevant getter, setter and construction methods.
So during the build a file called 'arch/object/structures_gen.h' will get generated from this .bf file using the bitfield_gen.py tool in the Makefile rule '%_gen.h:' that contains all the functions. This file gets removed after compilation when doing standalone kernel builds.

Hi Kenneth,

After you build the kernel, you can find its definition in build/kernelkernel_final.c file.

But I do no know how it is generated.

I guess it is generated by some scripts or preprocessor.

I also hope the answer from sel4 expert.

Best,

Yuxin

Hello everyone,

Currently I'm going through the source code of seL4. I find function in seL4\src\object\Tcb.c that I can't find it's definition.

In line 59, tcbSchedEnqueue calls a function 'thread_state_ptr_set_tcbQueued(&tcb->tcbState, true)'. However, even with the help of Source Insight I still can't locate the definition of 'thread_state_ptr_set_tcbQueued' . Does anyone know where it is ?

Thanks in advance.

Best regards,

Kenneth.
