How to tell if a PCI device is supported on Red Hat Enterprise Linux 7 and 8

Updated 2019年三月1日05:36 -

RHEL6 provided a modules.pcimap file that users could check to determine whether their devices were supported. This file is no longer available on RHEL 7 and RHEL 8, but the modules.alias file can be a useful replacement.

1. Determine the device's PCI ID

You can find this out from the manufacturer of your device, or use lspci -nn, like so.

Raw

# lspci -nn | grep Ether
00:19.0 Ethernet controller [0200]: Intel Corporation 82579LM Gigabit Network Connection [8086:1502] (rev 04)

The PCI ID is made up of a Vendor ID and a Device ID. The PCI ID is displayed after the device description, in the format [XXXX:YYYY], where XXXX is the Vendor ID, and YYYY is the Device ID. In this case, the PCI ID is [8086:1502], the Vendor ID is 8086, and the Device ID is 1502.

2. Check kernel modules for support

Search for the Vendor and Device ID in the installed kernel modules.

Raw

# egrep -i "<VendorID>.*<DeviceID>" /lib/modules/$(uname -r)/modules.alias

If no result returns, the device is not supported.

For example,

Raw

# egrep -i "8086.*1502" /lib/modules/$(uname -r)/modules.alias
alias pci:v00008086d00001502sv*sd*bc*sc*i* e1000e

The device with the PCI ID of [8086.1502] is supported by the e1000e kernel module.

Raw

# egrep -i "abcd.*1234" /lib/modules/$(uname -r)/modules.alias

The device with the PCI ID of [abcd.1234] is not supported on RHEL7.
