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
