Oracle yatulutsanso zosintha zachisanu za Unbreakable Enterprise Kernel R5, yoyikidwa kuti igwiritsidwe ntchito pakugawa kwa Oracle Linux ngati njira ina ya phukusi lokhazikika ndi kernel yochokera ku Red Hat Enterprise Linux. Kernel ikupezeka pa x86_64 ndi ARM64 (aarch64) zomangamanga. Magwero a kernel, kuphatikiza kugawanika kukhala zigamba pawokha, amasindikizidwa munkhokwe yapagulu ya Oracle Git.
Unbreakable Enterprise Kernel 5 idakhazikitsidwa pa Linux kernel 4.14 (UEK R4 idakhazikitsidwa pa kernel 4.1, ndipo UEK R6 idakhazikitsidwa pa 5.4), yomwe yasinthidwa ndi zatsopano, kukhathamiritsa ndi kukonza, ndipo yayesedwa kuti igwirizane ndi mapulogalamu ambiri. ikuyenda pa RHEL ndipo yakonzedwa mwapadera kuti igwire ntchito ndi mapulogalamu a mafakitale ndi zida za Oracle. Kuyika ndi src phukusi ndi UEK R5U5 kernel zakonzedwa Oracle Linux 7 (palibe zopinga kugwiritsa ntchito kernel iyi m'matembenuzidwe ofanana a RHEL, CentOS ndi Scientific Linux).
Kusintha kwakukulu:
- Khodi yomwe ili ndi udindo wochotsa cache ya tsamba la kukumbukira mu hypervisor ya KVM yakonzedwa bwino, zomwe zathandiza kuti machitidwe akuluakulu a alendo apite patsogolo ndikuchepetsa nthawi yawo yoyambira.
- Ziphuphu zakonzedwa ndipo kuwongolera kwapangidwa ku code ya btrfs, CIFS, ext4, NFS, OCFS2 ndi XFS file system.
- RDMA yasintha magwiridwe antchito a RDS (Reliable Datagram Sockets) zosinthira zolephera / zolephera ngati zitalephereka. Adawonjezera zida zatsopano za RDS zomwe zimatsata pogwiritsa ntchito eBPF ndi DTrace.
- Mawonekedwe a /sys/kernel/security/lockdown awonjezedwa kwa ma securityfs kuti azitha kuyang'anira Secure Boot Lockdown mode, yomwe imachepetsa mwayi wogwiritsa ntchito mizu ku kernel ndikuletsa njira za UEFI Secure Boot bypass.
- Madalaivala a zida asinthidwa, kuphatikiza mitundu yatsopano yoyendetsa LSI MPT Fusion SAS 3.0, BCM573xx, Intel QuickData, Intel i10nm EDAC, Marvell PHY, Microsoft Hyper-V ndi QLogic Fiber Channel HBA.
