I'm currently improving VDR's CAM handling, and while doing so
I came across what seems to be a bug in the AV7110 driver code.
If I do
int fd = open("/dev/dvb/adapter0/ca0", O_RDWR);
ca_slot_info_t sinfo;
sinfo.num = 0;
ioctl(fd, CA_GET_SLOT_INFO, &sinfo);
to check whether the CI adapter contains a CAM, the value of
sinfo.flags is 0 as long as no CAM is inserted. When I insert a CAM,
it first goes to 1 (CA_CI_MODULE_PRESENT) and then to 3
(CA_CI_MODULE_PRESENT | CA_CI_MODULE_READY). So far everything is ok.
However, when I remove the CAM from the slot, sinfo.flags still remains
set to 3. It never goes back to 0.
Is this a bug or "intended behavior"?
