Function Documentation

void MEM_CreateDescriptor (  MEM_Descriptor *  md, const MEM_Memmap  map, const caddr_t  addr, const size_t  bytes )

Create generic memory descriptor. Create a generic memory descriptor. This can be used to create any type of memory descriptor, but for those with extended data (such as a PCI configuration space descriptor), the extended data must be added by the caller. This function simply copies its arguments to the corresponding members of the memory descriptor. There is no argument checking, a user can create a completely bogus memory descriptor with this call. It is up to the routines that use the memory descriptor to validate it. Parameters: md  Pointer to location to build the descriptor. map  Type of memory. addr  Starting memory address. bytes  Size of memory, in bytes.

unsigned int MEM_CreateDescriptorFromDumpCommand (  MEM_Descriptor *  md_p, const void *  pkt_p )

Create memory descriptor from a memory dump command. This function creates a memory descriptor for use during a memory dump. It converts a valid memory dump command packet to a memory descriptor that describes the memory specified in the memory dump command. It is assumed that the memory dump command packet has been validated. Parameters: md_p  Pointer to location to build the descriptor. pkt_p  Pointer to valid memory dump command packet.

Here is the call graph for this function:

void* Mem_GatherRegisterSet (  void *  ptr  )

Gather register info. Get a CPU register dump and store it at the location defined by ptr. Returns the sum of ptr and the number of bytes used to dump the register set. Parameters: ptr  Pointer to location to store register dump. Returns: Sum of ptr and number of bytes used by register dump.
