3.3.5 Miscellaneous Request Structures
3.3.5.1 STATUS_REQ Structure
Used to indicate the internal state of the SEC2 core as well as the driver after the occurrence of an event. Returned
as a pointer by GetStatus() and embedded in all requests. This structure is defined in Sec2Notify.h
Each element is a copy of the contents of the same register in the
SEC2 driver. This structure is also known as
SEC2_STATUS through a typedef.
unsigned long ChaAssignmentStatusRegister[2];
unsigned long InterruptControlRegister[2];
unsigned long InterruptStatusRegister[2];
unsigned long IdRegister;
unsigned long ChannelStatusRegister[NUM_CHANNELS][2];
unsigned long ChannelConfigurationRegister[NUM_CHANNELS][2];
unsigned long CHAInterruptStatusRegister[NUM_CHAS][2];
unsigned long QueueEntryDepth;
unsigned long FreeChannels;
unsigned long FreeAfhas;
unsigned long FreeDesas;
unsigned long FreeMdhas;
unsigned long FreePkhas;
unsigned long FreeAesas;
unsigned long FreeKeas;
unsigned long BlockSize;
3.3.5.2 SEC2_NOTIFY_ON_ERROR_CTX Structure
Structure returned to the notify_on_error callback routine that was setup in the initial process request. This
structure contains the original request structure as well as an error and driver status.
unsigned long errorcode; // Error that the request generated
void *request; // Pointer to original request
SEC2_CANCELLED_REQUEST Error due to canceled request -1010
SEC2_INVALID_ADDRESS Error due to a NULL request -1011
