I'm porting a sound card(ens1370)to DDE, but found some errors in the function of kobj_map whic is in map.c(l4/pkg/dde/linux26/contrib.drivers/base/map.c) What's more, I check the ELF format of this sound card.The error is in the address of 821607. The related messages show as follows:
/home/wangjingyi/l4/tudos/l4/pkg/dde/linux26/contrib/drivers/base/map.c:58 mutex_lock(domain->lock); 821603: 8b 55 08 mov 0x8(%ebp),%edx 821606: 58 pop %eax 821607: 8b 82 fc 03 00 00 mov 0x3fc(%edx),%eax 82160d: 50 push %eax 82160e: e8 cd 65 02 00 call 847be0 <mutex_lock>
I was wondering what caused this error and how to fix it.
The first parameter given to kobj_map is wrong, probably 0. The caller needs to make sure a proper value is given.
