Hi,

I have two "interrupt_id" routines in my callout_interrupt.S file.
One is for a first board release while the second is for the latest
hardware version:
interrupt_id_ver16
interrupt_id_ver24

Also variable i.e. board_ver describes target release.
Now looking at the "board_ver" contents I would like
to do something like this:

if (board_ver == 16) then
interrupt_id_my_intr = interrupt_id_ver16;
else
interrupt_id_my_intr = interrupt_id_ver24;

and then pass interrupt_id_my_intr to the
intrs[] table:
const static struct startup_intrinfo intrs[] = {

...

{ 103, 20, 9, 0, 0, 0,

{ 0, 0, &interrupt_id_my_intr},

{ INTR_GENFLAG_LOAD_INTRMASK, 0, &interrupt_eoi_my_intr},

&interrupt_mask_my_intr,

&interrupt_unmask_my_intr,

0,

},

...

Is it possible ? How can I pass particular interrupt_id

callout to the same startup_intrinfo structure ?

Regards,

Jacek

Jacek,

you could do something like this, in your init_intrinfo.c:

const static struct startup_intrinfo intrs_ver16[] = {
{ base, num, cascade,
0, 0, 0,
{0, 0, &interrupt_id_ver16},
{INTR_GENFLAG_LOAD_INTRMASK, 0, &interrupt_eoi_both_vers},
&interrupt_mask_both_vers, &interrupt_unmask_both_vers, 0, 0,
},
};

const static struct startup_intrinfo intrs_ver24[] = {
{ base, num, cascade,
0, 0, 0,
{0, 0, &interrupt_id_ver24},
{INTR_GENFLAG_LOAD_INTRMASK, 0, &interrupt_eoi_both_vers},
&interrupt_mask_both_vers, &interrupt_unmask_both_vers, 0, 0,
},
};

void init_intrinfo() {

if(board_ver == 16)
add_interrupt_array(intrs_ver16, sizeof(intrs_ver16));
else
add_interrupt_array(intrs_ver24, sizeof(intrs_ver24));
}

Can I call "add_interrupt_array ()" in my init_intrinfo.c twice ?

void init_intrinfo() {
...

add_interrupt_array (common_intrs, sizeof(common_intrs));

if(board_ver == 16)
add_interrupt_array(intrs_ver16, sizeof(intrs_ver16));
else
add_interrupt_array(intrs_ver24, sizeof(intrs_ver24));
}

Yes, you can call add_interrupt_array() as many times as you want.

If you only have one struct startup_intrinfo to add, you can be a little
more
efficient and just use the add_interrupt() function (add_interrupt_array()
just calls add_interrupt() for all the array elements).
