Removes all items from a Storport managed singly linked list. A value indicating the use of the miniport micrisoft dump mode. When miniport drivers detect this value, they must return one of the values in the following table in the same member to indicate to the port driver that the miniport driver supports bit DMA.
A miniport-provided callback that is called after a notification from StorPortStateChangeDetected is processed. The Storport driver makes no assumptions about the HBA's interrupt usage, so the default value is zero.
The StorPortMoveMemory routine copies memory from one buffer to another.
The following are miniport driver routines: Specifies the maximum number of bytes the HBA can transfer in a single transfer mjcrosoft. It deallocates a range of noncached memory in the nonpaged portion of the system address space.
We appreciate your feedback. Our new feedback system is built on GitHub Issues.
SCSI_POWER_REQUEST_BLOCK structure
The Storport driver initializes this member to TRUEbecause its miniport drivers must support auto-request sense. A miniport driver notifies the Storport driver that the request has completed by calling the StorPortNotification function with the RequestComplete notification type. The miniport driver uses the StorPortNotification routine to notify the Storport driver of certain events and conditions.
A miniport driver can reset this member to a lesser value if the HBA has more limited capabilities or to a greater value, indicating that the HBA has extended bus capabilities. The miniport driver is notified to start a unit or handle a power state transition for a unit device.
PORT_CONFIGURATION_INFORMATION structure
There are no open issues. If this flag is set, the miniport driver should ignore the values in the PathIdTargetIdand Lun. The StorPortPoFxSetComponentResidency routine sets the estimated time for how long a storage device component is likely to remain idle after the component enters the idle condition. Specifies the bus-relative vector returned by the HBA.
The StorPortBusy routine notifies the port driver that the adapter is currently busy, handling outstanding requests. RtlZeroMemory The RtlZeroMemory routine fills a block of memory with zeros, given a pointer to the block and the length, in bytes, to be filled. This rule verifies that KeSetEvent is not called twice on the same event object.

A miniport driver's HwStorAdapterControl routine is mocrosoft to perform synchronous operations to control the state or behavior of an adapter, such as stopping or restarting the HBA for power management. It allocates a range of physically contiguous noncached, nonpaged memory, and returns the physical address of the allocated buffer.
Collapse the table of content. Contains a mask indicating the alignment restrictions for buffers required by the HBA for transfer operations. Product feedback Sign in to give documentation feedback. The StorPortLogSystemEvent routine storpport miniport drivers full access to the capabilities of the Windows kernel event facility, enabling miniport drivers to create event log entries that are truly useful in troubleshooting storage issues.
This allows the miniport driver to maintain knowledge about the state of the adapter between Plug and Play PnP stops and restarts, possibly enabling the miniport driver to optimize it's initialization procedure.
The Storport driver allocates memory for the access ranges and initializes this member. The ETW parameters are expressed as four name-value pairs.
