Driver Updates

Unbreakable Enterprise Kernel Release 5 supports a large number of hardware and devices. In close cooperation with hardware and storage vendors, Oracle has updated several device drivers from the versions in mainline Linux 4.14.35.

A complete list of the driver modules that are included in UEK R5U5, along with version information, is provided in the appendix at Driver Modules in Unbreakable Enterprise Kernel Release 5 Update 5 (x86_64).

Notable Driver Features and Updates

The following driver updates are included in UEK R5U5, relative to UEK R5U4:

  • Intel i10nm Error Detection And Correction (EDAC) driver

    The i10nm Error Detection And Correction (EDAC) driver (i10nm_edac) is enabled in this release to facilitate this functionality on Intel's next-generation 10nm-based server CPUs, code name Icelake.

  • Broadcom BCM573xx network driver

    The Broadcom BCM573xx network driver (bnxt_en) is updated to version 1.10.1 with additional patches. This update includes vendor-supplied patches and bug fixes.

  • Intel QuickData Technology driver

    The Intel QuickData Technology driver (ioatdma) is updated to version 5.00 and enabled in this release to facilitate this functionality on Intel's next-generation 10nm-based server CPUs, code name Icelake.

  • LSI MPT Fusion SAS 3.0 Device driver

    The LSI MPT Fusion SAS 3.0 Device driver (mpt3sas) is updated to version 36.100.00.00 to include vendor-supplied patches that bring the driver version in line with the upstream kernel release.

  • Marvell PHY driver

    The Marvell PHY driver (marvell) is updated to include vendor-supplied patches to improve stability on the Arm (aarch64) platform and also for several bug fixes.

  • QLogic Fibre Channel HBA driver

    The QLogic Fibre Channel HBA driver (qla2xxx) is updated to version 10.02.00.103-k and includes a large number of vendor-supplied patches to bring the driver version in line with the upstream kernel release.

  • Microsoft Hyper-V network driver

    The Microsoft Hyper-V network driver (hv_netvsc) is updated to include several vendor supplied patches to improve stability.

Cisco fnic 1.6 driver Unsupported

Cisco no longer supports the Cisco FCoE HBA Driver (fnic 1.6) that is sourced from the upstream kernel and which is available in most kernels, including UEK R5, UEK R6, and UEK R7. Cisco provides a fully supported UCS Linux driver (version 2.0.0.83, and later) that is tested on and compatible with Oracle Linux, with UEK R5 and later UEK releases, on the Cisco software download page. The driver package includes features that are not available in the currently included driver module such as NVMe support and multi-queue support.

Customers who are running Oracle Linux on Cisco servers must install the Cisco driver package to receive driver fixes, driver updates, new hardware support, and new feature support. Contact Cisco for more information about driver solutions on Oracle Linux.
