Step 2 - Install Your Driver

After you download your new driver, then you have to install it. To install a driver in Windows, you will need to use a built-in utility called Device Manager. It allows you to see all of the devices recognized by your system, and the drivers associated with them.

How to Open Device Manager

• In Windows 8.1 & Windows 10, right-click the Start menu and select Device Manager

• In Windows 8, swipe up from the bottom, or right-click anywhere on the desktop and choose 'All Apps' -> swipe or scroll right and choose 'Control Panel' (under Windows System section) -> Hardware and Sound -> Device Manager Hp 1000 printer driver download.

• In Windows 7, click Start -> Control Panel -> Hardware and Sound -> Device Manager

• In Windows Vista, click Start -> Control Panel -> System and Maintenance -> Device Manager

• In Windows XP, click Start -> Control Panel -> Performance and Maintenance -> System -> Hardware tab -> Device Manager button

How to Install drivers using Device Manager

1. Locate the device and model that is having the issue and double-click on it to open the Properties dialog box.

2. Select the Driver tab.

3. Click the Update Driver button and follow the instructions.

In most cases, you will need to reboot your computer in order for the driver update to take effect.

Tech Tip: Driver downloads and updates come in a variety of file formats with different file extensions. For example, you may have downloaded an EXE, INF, ZIP, or SYS file. Each file type has a slighty different installation procedure to follow.

If you are having trouble installing your driver, you should use the Driver Update Utility for Broadcom. It is a software utility that automatically finds, downloads and installs the right driver for your system. You can even backup your drivers before making any changes, and revert back in case there were any problems.

Try it now to safely update all of your drivers in just a few clicks. Once you download and run the utility, it will scan for out-of-date or missing drivers:

When the scan is complete, the driver update utility will display a results page showing which drivers are missing or out-of-date. You can update individual drivers, or all of the necessary drivers with one click.

These drivers support Netronome's line of Flow Processor devices,including the NFP4000, NFP5000, and NFP6000 models, which are alsoincorporated in the company's family of Agilio SmartNICs.

The repository builds the nfp.ko module which can be used to exposenetworking devices (netdevs) and/or user space access to the devicevia a character device.

The VF driver for NFP4000, NFP5000, and NFP6000 is available in upstreamLinux kernel since 4.5 release. The PF driver was added in Linux 4.11.This repository contains the same driver as upstream with necessarycompatibility code to make the latest version of the code build forolder kernels. We currently support kernels back to the 3.8 version,support for older versions can be added if necessary.

Compared to upstream drivers this repository contains:

• non-PCI transport support to enable building the driver for theon-chip control processor;
• support for netdev-based communication with the on-chip controlprocessor;
• optional low-level user space ABI for accessing card internals.

Additional targets:

The NFP4000 and NFP6000 devices require application specific firmwareto function. Firmware files contain card type (AMDA-* string), mediaconfig etc. They should be placed in /lib/firmware/netronome directory.

Firmware for basic NIC operation is available in the upstreamlinux-firmware.git repository, and if your distribution kernel is 4.11or newer you will most likely have it on your system already. Formore application specific firmware files please contactsupport@netronome.com.

Dealing with multiple projects

NFP hardware is fully programmable therefore there can be differentfirmware images targeting different applications. We recommend placingactual firmware files in application-named subdirectories in/lib/firmware/netronome and linking the desired files, e.g.:

You may need to use hard instead of symbolic links on distributionswhich use old mkinitrd command instead of dracut (e.g. Ubuntu).

After changing firmware files you may need to regenerate the initramfsimage. Initramfs contains drivers and firmware files your system mayneed to boot. Refer to the documentation of your distribution to findout how to update initramfs. Good indication of stale initramfsis system loading wrong driver or firmware on boot, but when driver islater reloaded manually everything works correctly.

Selecting firmware per device

Most commonly all cards on the system use the same type of firmware.If you want to load specific firmware image for a specific card, youcan use either the PCI bus address or serial number. Driver will printwhich files it's looking for when it recognizes a NFP device:

In this case if file (or link) called serial-00-12-34-aa-bb-5d-10-ff.nffwor pci-0000:02:00.0.nffw is present in /lib/firmware/netronome thisfirmware file will take precedence over nic_AMDA* files.

Note that serial-* and pci-* files are not automatically includedin initramfs, you will have to refer to documentation of appropriate toolsto find out how to include them.

The nfp.ko module provides offload capabilities for several TC flowerfeatures (with flower firmware loaded). The list of features include:

Match:

• Ingress Port.
• MAC source and destination address.
• VLAN tag control information.
• IPv4 and 6 source and destination address.
• Transport source and destination port.
• VXLAN header fields.
• MPLS header fields.

Action:

• Push/Pop Vlan.
• Drop.
• Output to Port.
• VXLAN Entunnel.
• Set MAC source and destination address.
• Set IPv4 and 6 source and destination address.
• Set transport source and destination port.

Before configuring filters, it is vital to remember to set up a queueingdiscipline. A simple example making use of the ingress qdisc follows:

Some filter examples follow:Match ipv4 type and output:

If you're running the driver with user space access enabled you will beable to use all Netronome's proprietary nfp-* tools. This section onlycovers standard debugging interfaces based on kernel infrastructure andwhich are always available.

Probing output

Most basic set of information is printed when driver probes a device.These include versions of various hardware and firmware components.

Netdev information

ethtool -i <ifcname> provides user with basic set of application FW andflash FW versions. Note that driver version for driver built in-tree willbe equal to the kernel version string and for out-of-tree driver it willeither contain the git hash if build inside a git repository or contentsof the .revision file. In both cases out of tree driver build will have(o-o-t) appended to distinguish from in-tree builds.

DebugFS

nfp_net directory contains information about queue state for all netdevsusing the driver. It can be used to inspect contents of memory rings andposition of driver and hardware pointers for RX, TX and XDP rings.

PCI BAR access

ethtool -d <ifcname> can be used to dump the PCI netdev memory.

NSP logs access

tools/dump_nsp_logs.sh script can be used to dump the logs of the ServiceProcessor. The script will read the log using standard ethtool APIs,however, if system is unable to initialize fully it can also use the Netronomevendor debug tools (if installed).

Control messages

Control messages which driver is exchanging with the FW on the card aresent to the devlink_hwmsg tracepoint. Note that trace_printk will onlydisplay first 64 bytes of the buffers. You can use the script from thisrepo to display the full messages, dump them to wireshark etc.:

The nfp.ko module provides drivers for both PFs and VFs. VFs can onlybe used as netdevs. In case of PF one can select whether to load thedriver in netdev mode which will create networking interfaces or onlyexpose low-level API to the user space and run health monitoring,diagnostics and control device from user space.

NOTE: if you're using Netronome-provided driver packages someof the defaults mentioned in this document may have been changedin the /etc/modprobe.d/netronome.conf file.

PF netdev mode

In this mode module provides a Linux network device interface onthe NFP's physical function. It requires appropriate FW image tobe either pre-loaded or available in /lib/firmware/netronome/ towork. This is the only mode of operation for the upstream driver.

Developers should use this mode if firmware is exposing vNICs on thePCI PF device.

By default (i.e. not make nfp_net build) low-level user space accessABIs of non-netdev mode will not be exposed, but can be re-enabled withappropriate module parameters (nfp_dev_cpp).

Nfpa Driver Course

PF non-netdev mode

This mode is used by the out-of-tree Netronome SDN products for healthmonitoring, loading firmware, and diagnostics. It is enabled by settingnfp_pf_netdev module parameter to 0. Driver in this mode will notexpose any netdevs of the PCI PF.

Developers should use this mode if firmware is only exposing vNICs onthe PCI VF devices.

This mode provides a low-level user space interface into the NFP(/dev/nfp-cpp-X file), which is used by development and debugging tools.It does not require a NFP firmware be loaded at device probe time.

VF driver

The nfp.ko contains a driver used to provide NIC-style access to VirtualFunctions of the device when operating in PCI SR-IOV mode.

For example, if a physical NFP6000 device was running Netronome SDN,and had assigned a rule matching 'all 172.16.0.0/24 received' to VF 5,then the NFP6000's SR-IOV device #5 would use this driver to provide aNIC style interface to the flows that match that rule.

nfp6000 quirks

NFP4000/NFP5000/NFP6000 chips need a minor PCI quirk to avoid system crashingafter particular type of PCI config space addresses from user space.If you're using the NFP on an old kernel you may see this message inthe logs:

Suggested solution is to update your kernel. The fix is present inupstream Linux 4.5, but major distributions have backported it toolder kernels, too. If updating the kernel is not an option and youare certain user space will not trigger the types of accesses whichmay fault - you can attempt using the ``ignore_quirks' parameteralthough this is not guaranteed to work on systems requiring the fix.
