Hi,
In our option ROM for our storage controller , I am trying to allocate some
memory using BS->AllocatePool().I see that the call just hangs and never comes
out.
Basically , we have a structure like this :
Struct A
{
//some elements
void * ptr;
//some elements
};
We are calling BS->Allocate pool with the arguments EfiBootServicesData,
sizeof(struct A), (void **)&p where "p" is of type Struct A * p .
This allocation is successful. The return value is success.
Now again after this allocation we do another call to BS->AllocatePool(). The
argument passed this time are EfiBootServicesData, sizeof(struct B),(void
**)&p->ptr . The intention is to later typecast p->ptr to struct *B and use it.
This allocation just hangs inside AllocatePool function and control never come
out of AllocatePool call.
Can I get come pointers to debug this issue? Am I missing any finer point here
? memmap command shows ample amount of memory in the system . Addresses
allocated in first allocation looks sane enough (0xFXXXXXXX range) .
Also I have used a skeleton EFI driver to allocate huge amount of memory
(around 30000 bytes at one time , running into 1000 loops) with a couple of
structure similar to structs A and B above , passed to the Allocatepoo() in the
same way as shown above. Allocation is successful in all the 1000 loops. Any
ideas ?
BTW the platform is Itanium (so I am building an IPF version of our oprom) , 64
bit machine. And the EDK is EDK 2.0. And system BIOS is confirming to UEFI 2.0.
Regards
Deb
