| #define MEM_REGISTER_SET_BYTES (768) |
Size in bytes of a register dump.
This is the size of a CPU register dump. There are 32 32-bit GPRs, 32 64-bit FPRs and 68 32-bit SPRs. That adds up to 656 bytes (164 words). A little extra space is allocated here (768 bytes, 192 words) in case a register or two was missed and needs to be added later.
For Memory Dump commands, a snapshot of the processor register values are gathered and stored in the dump context at the time the dump is started. The register values are then retrieved from the context as the dump progresses.

| enum _MEM_Memmap |
Memory map selection.
Enumerated types to select a memory map. This is derived from the memory dump and load telecommands and describes three types of memory accesses made by the LAT memory system:
MEMORY - regular byte-accessable RAM-like memories with no alignment requirements.
PCI_CFG - PCI configuration space.
REGISTER - PPCI memory-mapped registers. Memory map may contains "holes", so generic non-aligned bytes access not always allowed.

| ) |
Create a 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.
| 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 a memory descriptor from a 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.
| md_p | Pointer to location to build the descriptor. | |
| pkt_p | Pointer to valid memory dump command packet. |
