Storport behaves differently in some circumstances when it supports a “virtual” miniport instead of a miniport that is controlling real hardware. Set this value to 0 if no wait time is needed after a bus reset. Feedback We’d love to hear your thoughts. The size of per-logical-unit storage is specified via the SpecificLuExtensionSize field, described later in this topic. The StorPortFreeContiguousMemorySpecifyCache routine deallocates a range of noncached memory in the nonpaged portion of the system address space.

Specifies the bus-relative interrupt request level.
The Download Microcode Status diagnostic page includes information about microsoct status of one or more download microcode operations. Feedback We’d love to hear your thoughts.
Instead, we recommend using the Storport driver and Storport miniport driver models. Miniport storort must not modify this member. Feedback We’d love to hear your thoughts. Send comments about this topic to Microsoft.

We appreciate your feedback. The StorPortFreeContiguousMemorySpecifyCache routine deallocates a range of noncached memory in the nonpaged portion of the system address space. The StorPortPause routine pauses an adapter for the specified period of time.
Indicates the system DMA controller should be programmed for demand-mode rather than single-cycle operations. Product feedback Sign in to give micrpsoft feedback. Choose the type you’d like to provide: The current system performance counter value is queried is returned by the StorPortQueryPerformanceCounter routine.
StorPortDeviceBusy The StorPortDeviceBusy routine notifies the port driver that the specified logical unit is currently busy, handling outstanding requests. The Storport port driver makes no assumptions about the HBA’s interrupt usage, so the default value is zero. The StorPortPoFxIdleComponent routine decrements the activation reference count of a specified component of a storage device.
The miniport driver sets this member to one of the following values to control mapping for SRB data buffer addresses. It passes a pointer to the HBA-specific device extension in every call to a miniport driver.
The interval, in seconds, that the request can execute before the Storport driver determines that the request has timed out. Use these rules to verify that your driver correctly calls DDIs that are of particular interest to Storport virtual miniport VMiniport drivers.
The HwStorInitialize routine initializes the miniport driver after a system reboot or power failure occurs. Miniport drivers must not modify this value. 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. Removes an item from the front of a Storport managed singly linked list. You may also leave feedback directly on GitHub. This rule verifies that the handle to a registry key created with ZwCreateKey is subsequently used correctly by other ZwXxx routines.
Product feedback Sign in to give documentation feedback. A miniport driver’s HwStorAdapterControl routine is called to perform synchronous operations to control the state or behavior of an adapter, such as stopping or restarting the HBA for power management.
Product feedback Sign in to give documentation feedback. Set this member to zero if the miniport driver does not maintain per-LU information for which it requires storage. Allocations have no boundary alignment requirement. The ZwOpenKey routine must not be called on an already open handle. Our new feedback system is built on GitHub Issues. The Storport driver makes no assumptions about the HBA’s interrupt usage, so the default value is zero. The Storport driver will set this to a default value of
