Generation of _soc_inthandlers.h for Zephyr

[sunilkumardommati]

Hi,

We are working on porting Zephyr to our platform.
We are not sure on how to generate the _soc_inthandlers.h file which is placed at zephyr\soc\xtensa\soc_vendor\soc\include path.

I tried to generate using, zephyr\arch\xtensa\core\xtensa_intgen.py with our platform specific core-isa.h as input.
But its only producing the following code but not complete interrupt handlers.

`/*

• THIS FILE WAS AUTOMATICALLY GENERATED. DO NOT EDIT.
• Functions here are designed to produce efficient code to
• search an Xtensa bitmask of interrupts, inspecting only those bits
• declared to be associated with a given interrupt level. Each
• dispatcher will handle exactly one flagged interrupt, in numerical
• order (low bits first) and will return a mask of that bit that can
• then be cleared by the calling code. Unrecognized bits for the
• level will invoke an error handler.
  */

#include <xtensa/config/core-isa.h>
#include <zephyr/sys/util.h>
#include <zephyr/sw_isr_table.h>

static inline int _xtensa_handle_one_int0(unsigned int mask)
{
return 0;
}
`

please let me know if I’m missing anything here.

@sunilkumardommati you may want to ask on Zephyr project, but @andyross may be able to help you here too.

@andyross, could you please let us know your inputs on this issue?

Also check the Cmakefile.txt as IIUC it invokes the generation of this file.

@lgirdwood , we've got inputs in Zephyr devel forum that we need to run the xtensa_intgen.tmpl through the toolchain's preprocessor, and then use xtensa_intgen.py to process the output.
With this, we are able to generate the int handlers file.
