Oracle e lokolitse Unbreakable Enterprise Kernel R5U2

Khampani ea Oracle lokollotsoe ntlafatso ea karolo ea bobeli bakeng sa kernel Enterprise Kernel R5, e behiloeng bakeng sa tšebeliso ea Oracle Linux e le mokhoa o mong oa sephutheloana se tloaelehileng le kernel ho tsoa ho Red Hat Enterprise Linux. Kernel e fumaneha bakeng sa meralo ea x86_64 le ARM64 (aarch64). Mehloli ea kernel, ho kenyelletsa le karohano ea li-patches ka bomong, phatlalalitsoe sebakeng sa polokelo ea sechaba sa Oracle Git.

Sephutheloana sa Unbreakable Enterprise Kernel 5 se thehiloe holim'a kernel Linux 4.14 (UEK R4 e ne e ipapisitse le 4.1 kernel), e nchafalitsoeng ka likarolo tse ncha, ntlafatso le litokiso, hape e lekoa bakeng sa ho lumellana le lits'ebetso tse ngata tse sebetsang ho RHEL, mme e ntlafalitsoe ka ho khetheha ho sebetsa le software ea indasteri ea Oracle le hardware. Ho kenya le liphutheloana tsa src ka kernel ea UEK R5U1 lokisitsoe bakeng sa Oracle Linux 7.5 le 7.6 (ha ho na litšitiso ho sebelisa kernel ena liphetolelong tse tšoanang tsa RHEL, CentOS le Scientific Linux).

Senotlolo ntlafatso:

• Li-patches li fetisitsoe ka ts'ebetsong ea "PSI" (Pressure Stall Information), e u lumellang ho sekaseka tlhahisoleseling mabapi le nako ea ho leta bakeng sa ho fumana lisebelisoa tse fapaneng (CPU, memori, I / O) bakeng sa mesebetsi e itseng kapa lihlopha tsa lits'ebetso ka har'a sehlopha. . Ho sebelisa PSI, basebelisi ba sebaka sa basebetsi ba ka hakanya ka nepo boemo ba tsamaiso ea tsamaiso le mekhoa ea ho fokotseha ha e bapisoa le Karolelano ea Mojaro;
• Bakeng sa cgroup2, cpuset resource controller e nolofalitsoe, e fanang ka mokhoa oa ho fokotsa ho behoa ha mesebetsi ho li-memory node tsa NUMA le li-CPU, ho lumella tšebeliso ea lisebelisoa feela tse hlalositsoeng bakeng sa sehlopha sa mosebetsi ka sebopeho sa cpuset pseudo-FS;
• Moralo oa ktask o kentsoe tšebetsong ho bapisa mesebetsi e kernel e jang lisebelisoa tsa bohlokoa tsa CPU. Mohlala, ho sebelisa ktask, parallelization ea ts'ebetso ho hlakola likarolo tsa maqephe a memori kapa ho sebetsana le lethathamo la li-inode li ka hlophisoa;
• Ka DTrace eketsoe ts'ehetso ea ho nka lipakete ka libpcap ho sebelisa ketso e ncha "pcap(skb,proto)" Ka mohlala "dtrace -n 'ip:::send {pcap((void *)arg0, PCAP_IP); }'";
• Ho tsoa ho li-kernel tse ncha fetisoa litokiso ts'ebetsong ea litsamaiso tsa lifaele tsa btrfs, CIFS, ext4, OCFS2 le XFS;
• Ho tloha kernel 4.19 fetisoa liphetoho tse amanang le tšehetso bakeng sa li-hypervisors tsa KVM, Xen le Hyper-V;
• E ntlafalitsoe bakhanni ba lisebelisoa le tšehetso e atolositsoeng bakeng sa li-drive tsa NVMe (liphetoho ho tloha ho li-kernel 4.18 ho ea ho 4.21 li fetisitsoe);
• Litokiso li sebelisitsoe ho ntlafatsa ts'ebetso ho li-platform tsa ARM.
