I am getting BSOD - driver IRQL not less or equal (storport.sys) on my two year old Alienware Desktop. This being a new Windows 10 system, nothing that I find on the net will directly pertain. Windows drivers are implemented in a layered architecture, so in our case the STORPORT driver interfaces directly with the adapter or miniport driver. The STORPORT driver is responsible for managing requests and queues, and providing other upper level functions. Mar 27, 2007 An updated Storport storage driver is available for Windows Server 2003. Content provided by Microsoft. This article describes an updated Microsoft Storport storage driver for host bus adapter (HBA) storage devices. https://cowboyclever461.weebly.com/blog/sony-vgn-fw139e-drivers-for-mac. The Storport driver performs a time-based pause before the Storport driver retries the command.
-->The HwStorPassiveInitializeRoutine callback routine is called after the HwStorInitialize routine when the current IRQL is at PASSIVE_LEVEL. The HwStorPassiveInitializeRoutine callback is set by calling the StorPortEnablePassiveInitialization routine. Initializing of the miniport's deferred procedure calls (DPCs) occurs in the HwStorPassiveInitializeRoutine callback.
Syntax
Parameters
Storport Sys Error Windows 10
Es1371 sound card drivers for mac.
DeviceExtension
Return Value
The HwStorPassiveInitializeRoutine routine returns TRUE if the miniport successfully initialized the processing of DPCs, or FALSE if the initialization process failed.

Remarks
The HwStorPassiveInitializeRoutine routine should initialize any DPCs that the miniport driver will use. The port driver calls HwStorPassiveInitializeRoutine at PASSIVE_LEVEL without any spin locks held. Gt-p5210 drivers for mac. Interrupts are enabled while this routine is called.
The name HwStorPassiveInitializeRoutine is just a placeholder. The actual prototype for this callback routine is defined in storport.has follows:
The port driver calls the What Is Storport Driver
HwStorPassiveInitializeRoutine routine at PASSIVE IRQL without acquiring any spin locks.Examples
To define an HwStorPassiveInitializeRoutine callback function, you must first provide a function declaration that identifies the type of callback function you’re defining. Windows provides a set of callback function types for drivers. Declaring a function using the callback function types helps Code Analysis for Drivers, Static Driver Verifier (SDV), and other verification tools find errors, and it’s a requirement for writing drivers for the Windows operating system.
For example, to define a HwStorPassiveInitializeRoutine callback routine that is named MyHwPassiveInitialize, use the HW_PASSIVE_INITIALIZE_ROUTINE type as shown in this code example:

In addition to the SCSI Port driver, Microsoft Windows Server 2003 and later versions provide Storport (storport.sys), a storage port driver that is especially suitable for use with high-performance buses, such as fibre channel buses, and RAID adapters.
Virtual Storport Miniport
There are several advantages to using Storport rather than the SCSI Port driver:
- Improved performance, both in terms of throughput and the system resources that are utilized.
- Improved miniport driver interface that addresses the needs of high-end storage vendors, particularly host-based RAID and fibre channel vendors.
All vendors are encouraged to use Storport where possible, rather than the SCSI Port driver. Certain restrictions apply, however. Storport cannot be used with adapters or devices that do not support Plug and Play. All DMA devices must have bus-mastering DMA capability, because Storport does not support programmed I/O or subordinate-mode DMA. Other restrictions apply in regard to tagged queuing, autorequest sense, WMI support, the sort of SCSI inquiry data that devices must report, and booting directly from an adapter's ROM BIOS. For a detailed list of restrictions on the use of the Storport driver, see Requirements for Using Storport with an Adapter.
To better utilize the investment that vendors have made in SCSI Port miniport drivers, Storport follows the SCSI Port-miniport driver architecture with very few modifications. Changes to the SCSI Port driver interface were made in areas where new algorithms were able to produce measurable speed increases, or where it was necessary to add support for high-speed buses.
