- Kupyolera mu fanotify file tracking tracking API, mutha kulandira zidziwitso fayilo ikatsegulidwa kuti ichitike.
- Wolamulira wa cpuset waphatikizidwa, womwe ungagwiritsidwe ntchito kuchepetsa magulu a njira pogwiritsa ntchito ma CPU ndi ma node a NUMA.
- Thandizo la zipangizo za ARM zotsatirazi zikuphatikizidwa: Qualcomm QCS404, Allwinner T3, NXP/Freescale i.MX7ULP, NXP LS1028A, i.MX8, RDA Micro RDA8810PL, Rockchip Gru Scarlet, Allwinner Emlid Neutis N5, ndi ena ambiri.
- Kupititsa patsogolo kagawo kakang'ono ka ARM: memory hot-plug, Meltdown ndi Specter chitetezo, 52-bit memory adilesi, etc.
- Thandizo la malangizo a WBNOINVD a x86-64.
Memory subsystem:
- Kusintha kwa tag yoyeserera ndi kukumbukira pang'ono kulipo pa chida cha KASAN pamapulatifomu a ARM64.
- Kugawikana kwa kukumbukira kwachepetsedwa kwambiri (mpaka 90%), zomwe zimapangitsa kuti Transparent HugePage imagwirira ntchito bwino.
- Kuchita kwa mremap(2) m'malo akulu okumbukira kwawonjezedwa mpaka nthawi 20.
- Mu makina a KSM, jhash2 imasinthidwa ndi xxhash, chifukwa chake liwiro la KSM pa machitidwe a 64-bit lawonjezeka ndi kasanu.
- Kusintha kwa ZRam ndi OOM.
Tsekani zida ndi mafayilo amafayilo:
- Makina a blk-mq okhala ndi mizere yamitundu yambiri yama mizere yopempha akhala wamkulu pazida zotchinga. Ma code onse omwe si a mq achotsedwa.
- Kusintha kwa chithandizo cha NVMe, makamaka pankhani yogwiritsira ntchito chipangizo pa intaneti.
- Kwa Btrfs, chithandizo chonse cha mafayilo osinthana chimakhazikitsidwa, komanso kusintha FSID popanda kulembanso metadata.
- Kuyimba kwa ioctl kwawonjezedwa ku F2FS kuti muwonetsetse FS kudzera pa fsck.
- Integrated BinderFS - pseudo-FS yolumikizirana. Imakulolani kuyendetsa maulendo angapo a Android pamalo amodzi.
- Zosintha zingapo mu CIFS: Cache ya DFS, mawonekedwe owonjezera, smb3.1.1 protocol.
- ZRam imagwira ntchito bwino kwambiri ndi zida zosinthira zosagwiritsidwa ntchito, kupulumutsa kukumbukira.
Chitetezo ndi virtualization:
- Anawonjezera ntchito ya Streebog hash (GOST 34.11-2012), yopangidwa ndi FSB ya Russian Federation.
- Kuthandizira kwa Adiantum encryption algorithm yopangidwa ndi Google pazida zotsika mphamvu.
- Ma aligorivimu XChaCha12, XChaCha20 ndi NHPoly1305 zikuphatikizidwa.
- Kugwira mafoni a seccomp tsopano kungasunthidwe kumalo ogwiritsira ntchito.
- Kwa machitidwe a alendo a KVM, chithandizo cha Intel processor Trace extensions chimakhazikitsidwa ndi kuwonongeka kochepa.
- Kusintha kwa KVM/Hyper-V subsystem.
- Dalaivala wa virtio-gpu tsopano amathandizira kuyerekezera kwa EDID kwa oyang'anira.
- Dalaivala wa virtio_blk amagwiritsa ntchito kuyimba foni.
- Kukhazikitsidwa kwachitetezo cha kukumbukira kwa NV kutengera mafotokozedwe a Intel DSM 1.8.
Oyendetsa Chipangizo:
- Zosintha pa DRM API kuti zithandizire kulunzanitsa kosinthika (gawo la muyezo wa DisplayPort) ndi mitengo yotsitsimutsa (gawo la HDMI).
- Muyezo wa Display Stream Compression umaphatikizidwira kuphatikizika kosataya kwa makanema amakanema omwe amayankhidwa pazithunzi zapamwamba kwambiri.
- Dalaivala wa AMDGPU tsopano amathandizira FreeSync 2 HDR ndi GPU kukonzanso kwa CI, VI, SOC15.
- Woyendetsa kanema wa Intel tsopano amathandizira tchipisi ta Amber Lake, YCBCR 4:2:0 ndi YCBCR 4:4:4 mafomu.
- Dalaivala wa Nouveau amaphatikizanso ntchito ndi makanema amakanema abanja la Turing TU104/TU106.
- Madalaivala ophatikizika a Raspberry Pi touchscreen, CDTech panels, Banana Pi, DLC1010GIG, etc.
- Dalaivala wa HDA amathandizira batani la "jack", zizindikiro za LED, zida za Tegra186 ndi Tegra194.
- Dongosolo lolowetsamo laphunzira kugwira ntchito ndikupukuta mwatsatanetsatane pa mbewa za Microsoft ndi Logitech.
- Zosintha zambiri pamadalaivala amakamera, ma TV tuner, USB, IIO, ndi zina zambiri.
Network subsystem:
- Stack ya UDP imathandizira makina a zero-copy potumiza deta pa socket popanda kusungitsa pakati.
- Makina a Generic Receive Offload nawonso awonjezedwa pamenepo.
- Kupititsa patsogolo ntchito zofufuzira mu ndondomeko za xfrm pamene pali zambiri.
- Kutha kutsitsa ma tunnel awonjezedwa kwa dalaivala wa VLAN.
- Zosintha zingapo zothandizira Infiniband ndi maukonde opanda zingwe.
