Hi,
I've been playing with a modified version of the existing Cinergy T²
driver which has been merged to fit into current dvb-usb driver framework
like the rest of the drivers existing under the dvb-usb directory in
HG-tree. However, there are a couple of things which I have a problem
with:
1) For some reason if I define a release handler funtion for the frontend
(of type struct dvb_frontend_ops ) --> .release = cinergyt2_fe_release and
then physically remove the usb-device from the computer and re-connect
immediately after, the kernel modules ref-counter goes backwards to
unsigned 32-bit -1 (ie value is shown to be 4294967295 by the lsmod-cmd).
This seems to happen because of the dvb_frontend_detach() calls the
frontends release handler if it has been defined and immediately after it
calls symbol_put_addr(ptr).
#ifdef CONFIG_DVB_CORE_ATTACH
void dvb_frontend_detach(struct dvb_frontend* fe)
{
void *ptr;
if (fe->ops.release_sec) {
fe->ops.release_sec(fe);
symbol_put_addr(fe->ops.release_sec);
}
if (fe->ops.tuner_ops.release) {
fe->ops.tuner_ops.release(fe);
symbol_put_addr(fe->ops.tuner_ops.release);
}
ptr = (void*)fe->ops.release;
if (ptr) {
fe->ops.release(fe);
symbol_put_addr(ptr);
}
}
#else
If I don't define the release handler for the frontend, the modules
ref-counter stays 0 as expected.
2) Is there any chance to change the "struct dvb_usb_rc_key" defined in
dvb-usb.h as currently it contains two fields of type u8, while the
Cinergy T² device sepcs say that the device sends 32-bit remote control
codes and therefore I don't know how to get the Cinergy T² remote
controller handling to fit the current dvb-usb system ... ?
(this can be seen in the current Cinergy T² driver sources as well)
struct dvb_usb_rc_key {
u8 custom,data;
^^^^^^^^^^^^^^^^^^^^^
u32 event;
};
Regards,
Tomi Orava
