Oracle yakaburitsa yechipiri inoshanda dhizaini yeIsingaputsike Enterprise Kernel R6, yakamisikidzwa kuti ishandiswe mukugovera Oracle Linux seimwe nzira kune yakajairwa package ine kernel kubva kuRed Hat Enterprise Linux. Iyo kernel inowanikwa kune x86_64 uye ARM64 (aarch64) zvivakwa. Iyo kernel masosi, kusanganisira kuparara kuita zvigamba zvega, zvinoburitswa muruzhinji Oracle Git repository.
Isingaputsike Enterprise Kernel 6 yakavakirwa paLinux 5.4 kernel (UEK R5 yaive yakavakirwa pa4.14 kernel), iyo inogadziridzwa neatsva maficha, optimizations negadziriso, uye zvakare inoedzwa kuti ienderane neakawanda maapplication ari kushanda paRHEL, uye akagadziridzwa zvakananga. yekushanda nemaindasitiri software uye Oracle midziyo. Kuiswa uye src mapakeji ane UEK R6 kernel akagadzirirwa Oracle Linux 7.x uye 8.x.
Shanduko huru:
- Kune mapoka, itsva slab memory controller yakawedzerwa, iyo inokosha pakufambisa slab accounting kubva pachiyero peji peji kusvika kune kernel chinhu chinhanho, izvo zvinoita kuti zvikwanise kugovera mapeji e-slab mumapoka akasiyana, panzvimbo yekugovera akaparadzana slab cache kune imwe neimwe. cgroup. Iyo yakarongwa nzira inoita kuti iwedzere kugona kwekushandisa slab, kuderedza saizi yendangariro inoshandiswa kuslab kusvika ku50%, kuderedza zvakanyanya kurangarira kwese kudyiwa kwekernel uye kuderedza kupatsanurwa kwendangariro.
- Kune Mellanox ConnectX-6 Dx zvishandiso, mutyairi mutsva wevpda akawedzerwa nerutsigiro rwevDPA (vHost Data Path Acceleration) chimiro, chinokutendera kuti ushandise hardware kukwidziridza I/O zvichibva paVirtIO mumashini chaiwo.
- Kuvandudzwa kwakabatana nerutsigiro rweNVMe zvishandiso kwakatakurwa kubva kuLinux kernel 5.9.
- Kugadziriswa uye kuvandudzwa kwakaiswa kune Btrfs, CIFS, ext4, NFS, OCFS2 uye XFS faira masisitimu.
- Vatyairi vakagadziridzwa, kusanganisira lpfc 12.8.0.5 (Broadcom Emulex LightPulse Fiber Channel SCSI) nerutsigiro rwe256-gigabit mode yeSCSI Fiber Channel, mpt3sas 36.100.00.00 (LSI MPT Fusion SAS 3.0), qla2x0.02.00.103xXNUMX Fiber Channel XNUMX. HBA).
- Yakawedzera kuyedza rutsigiro rweVPN Wireguard, inoshandiswa padanho re kernel.
- NFS yakawedzera tsigiro yekuyedza yekukwanisa kukopa mafaera zvakananga pakati pemaseva, anotsanangurwa muNFS 4.2 yakatarwa.
- Murongi webasa ane hunyanzvi hwekuyedza kudzikamisa kuita kwakafanana kwemabasa akakosha pane akasiyana CPU cores kuvharira nzira dzinobuda dzine chekuita nekushandiswa kwecache yakagovaniswa paCPU.
