Slot Control API
The callback function has the following prototype:
VOID (*HSI_SLOT_EVENT_CALLBACK)(
IN void *pContext,
IN BOOLEAN HscError,
IN HSI_SLOT_EVENT_INFO *pSlotInfo );
The arguments have the following semantics:
pContext - | Opaque context pointer. This is the same value that was originally passed |
| to HsiSetSlotEventCallback(). |
HscError - | The value TRUE indicates that a hardware error has been detected in the |
| Hot Swap Controller, and FALSE indicates a state change in one of the |
| slots. |
pSlotInfo - | If HscError is FALSE, this argument is the pointer to the structure that |
| contains the slot number and the new state of the slot that has changed |
| its state. If HscError is TRUE, the value of this argument is reserved and |
| undefined. |
The slot event information structure is defined as follows.
typedef struct
HSI_SLOT_EVENT_INFO_STRUCT
{
UINT32 SlotNumber;
BOOLEAN Present;
BOOLEAN Powered;
BOOLEAN Healthy;
BOOLEAN InReset;
} HSI_SLOT_EVENT_INFO;
with the fields specified as:
SlotNumber - | the number of the slot that has changed its state |
Present - | the board presence status for the slot |
Powered - | the power status for the slot |
Healthy - | the health status for the board in the slot |
InReset - | the reset status of the slot |
Note: If Powered is TRUE, the value for Present is not valid, and that if Powered is FALSE, the value for Healthy is not valid.
This function shall be implemented as part of the HA Slot Control Interface on platforms where the Hot Swap Controller can automatically detect and signal the occurrence of slot status changes.
