On Windows 10, a device driver is an essential piece of code, which allows the system to interact with a specific hardware (such as graphics card, storage driver, network adapter, Bluetooth, etc. A library of over 250,000 device drivers, firmware, BIOS and utilities for Windows.

Note

The ATA port driver and ATA miniport driver models may be altered or unavailable in the future. Instead, we recommend using the Storport driver and Storport miniport driver models.

In addition to the SCSI Port Driver and the Storport Driver, Windows Vista and later versions of the Windows operating system provide the ATA port driver (Ataport.sys), a storage port driver that is especially suitable for use with IDE controllers.

The most significant difference between the ATA port driver and other system-supplied storage port drivers is the protocol that the ATA port driver uses to communicate with other drivers. All other system-supplied storage port drivers use SCSI request blocks (SRBs) to communicate both with higher-level drivers, such as storage class drivers, and with miniport drivers. The ATA port driver uses SRBs to communicate with higher-level drivers only. To communicate with its miniport drivers, ATA port uses a packet called an IDE request block (IRB), which is defined by the IDE_REQUEST_BLOCK structure. IRBs are better designed than SRBs to the characteristics of ATA devices.

Another difference between the ATA port driver and other system-supplied storage drivers is that the ATA port driver shields ATA miniport drivers from certain requirements that are defined by the SCSI standard. For example, the ATA port driver uses ATA commands to collect the equivalent of SCSI sense data from the ATA miniport driver, translates the data so that it complies with a SCSI sense data format, and passes the data to higher-level drivers as if it were SCSI sense data. Therefore, ATA miniport drivers do not have to respond directly to requests from higher-level drivers for SCSI sense data.

The ATA miniport driver interface closely resembles the SCSI port driver interface. Therefore, if you have already written a SCSI miniport driver, you should be able to easily learn how to write an ATA miniport driver. Drivers for current ATA/ATAPI technologies, such as Serial ATA (SATA), should use the higher performance Storport miniport interface.

Together with the ATA port driver, the operating system provides a default ATA miniport driver and a default controller minidriver. The system-supplied default drivers work for most controller hardware, and we strongly recommend that the default minidrivers be used wherever possible.

The Ethernet switch device driver model (switchdev) is an in-kernel drivermodel for switch devices which offload the forwarding (data) plane from thekernel.

Figure 1 is a block diagram showing the components of the switchdev model foran example setup using a>FIB_EVENT_ENTRY_ADDused for both adding a new FIB entry to the device,or modifying an existing entry on the device.FIB_EVENT_ENTRY_DELused for removing a FIB entryFIB_EVENT_RULE_ADD,FIB_EVENT_RULE_DELused to propagate FIB rule changes

FIB_EVENT_ENTRY_ADD and FIB_EVENT_ENTRY_DEL events pass:

to add/modify/delete IPv4 dst/dest_len prefix on table tb_id. The *fistructure holds details on the route and route’s nexthops. *dev is oneof the port netdevs mentioned in the route’s next hop list.

Routes offloaded to the device are labeled with “offload” in the ip routelisting:

The “offload” flag is set in case at least one device offloads the FIB entry.

Nexthop Resolution¶

Drivers Sharp Port Devices Bluetooth

The FIB entry’s nexthop list contains the nexthop tuple (gateway, dev), but forthe switch device to forward the packet with the correct dst mac address, thenexthop gateways must be resolved to the neighbor’s mac address. Neighbor macaddress discovery comes via the ARP (or ND) process and is available via thearp_tbl neighbor table. To resolve the routes nexthop gateways, the drivershould trigger the kernel’s neighbor resolution process. See the rockerdriver’s rocker_port_ipv4_resolve() for an example.

The driver can monitor for updates to arp_tbl using the netevent notifierNETEVENT_NEIGH_UPDATE. The device can be programmed with resolved nexthopsfor the routes as arp_tbl updates. The driver implements ndo_neigh_destroyto know when arp_tbl neighbor entries are purged from the port.
