◆ chDbgStackOverflowPanic()

void chDbgStackOverflowPanic ( thread_t * otp )

this depends on chcore.h patch +void chDbgStackOverflowPanic(thread_t *otp);

chSysHalt("stack overflow"); \
chDbgStackOverflowPanic(otp); \

◆ initEfiWithConfig()

    // This sets the "unwind point" that we can jump back to later with longjmp if we have
    // an assertion failure. If that happens, setjmp() will return non-zero, so we will
    // return immediately from this function instead of trying to init hardware again (which failed last time)

        return;
