Nhasi Linus Torvalds yakaburitswa vhezheni 5.13 yeLinux kernel iyo iyo inowanikwa yekutanga rutsigiro rweiyo nyowani Apple M1 chip nerutsigiro rwekutanga, matsva ekuchengetedza maficha yeLinux 5.13 senge Landlock LSM, Clang CFI rutsigiro uye kugona kurongedza iyo kernel stack offset pane yega system kufona, pamwe neiyo sTsigiro yeFreeSync HDMI uye kutanga kuitiswa kweAldebaran, pakati pevamwe.
About 47% yeshanduko dzese dzakaburitswa muna 5.13 dzakabatana nemadhiraivha emidziyo, ingangoita 14% yeshanduko inoenderana nekugadzirisa yakatarwa kodhi yezvivakwa zvehardware, 13% zvine hukama nesitaki stack, 5% zvine hukama nemafaira masystem uye 4% zvine hukama. kune yemukati kernel subsystems.
Torvalds akadana iyo nyowani vhezheni "yakakura kwazvo."
“Takaita vhiki rakanyarara kubva rc7, uye ini handione chikonzero chekunonoka 5.13. Kutenderera kwevhiki kudiki, iine makumi masere nemasere chete asina kushandiswa (uye mamwe acho anongova marara). Ehezve, nepo vhiki rekupedzisira raive diki uye rakanyarara, 88 seyakazara yakakura. Muchokwadi, ndeimwe yeakanyanya kukosha 5.13.x vhezheni, ine anopfuura gumi nematanhatu anoita (anopfuura zviuru gumi nemana kana iwe ukaverenga kubatanidzwa), kubva kune vanopfuura zviuru zviviri vanogadzira. Asi ichi chiitiko chinowanzoitika, kwete chiitiko chakasiyana chinosiyaniswa nehunhu hwacho husina kujairika, ”akanyora kudaro Torvalds.
Main nyowani maficha eLinux 5.13
Chimwe chezvinhu zvakakosha zvakakosha zveLinux 5.13 kernel ndiyo kutanga rutsigiro rweApple's M1 machipisi, mairi panguva ino iwe unongova nerutsigiro rwehardware uye kuitisa kodhi, asi zvakawanda optimization zvinotarisirwa. Iyo yekumhanyisa yekumhanyisa haisati yavapo, asi zvinotarisirwa kuti mune inotevera vhezheni yekutanga rutsigiro ichave yatove nayo futi.
Dzimwe nhau dzinounzwa muLinux 5.13 zvine chekuita nekuchengetedza ndeye Landlock, inova nyowani yekuchengetedza module inogona kumhanya padivi peSELinux kugadzirisa zvirinani maitiro. Iyo inobvumidza kudzikamisa kudyidzana nemaitiro eboka rekunze kwenharaunda uye rakagadziriswa nechinangwa chekuzviparadzanisa nzira dzakadai seSandbox, XNU, Capsicum's FreeBSD uye OpenBSD Pledge / Unveil.
Nerubatsiro rweLandlock, chero maitiro, kusanganisira asiri akadzika midzi, anogona kuve akavimbika ari ega uye kudzivirira kupfuudza kuzviparadzanisa kana paine njodzi kana shanduko yekushandisa yakaipa. Landlock inogonesa maitiro ekugadzira akachengetedzeka emarara mabhokisi ayo anoitwa seyekuwedzera rukoko pamusoro penzvimbo dziripo svomhu yekudzivirira nzira. Semuenzaniso, chirongwa chinogona kuramba kupinda kwemafaira kunze kweye dhairekitori rinoshanda.
Uyewo zvinowedzera kune iyo RISC-V yekuvakisa inosimbiswa, Zvakanaka, mune iyi nyowani vhezheni rutsigiro inoitwa kexec, kuparara kwekurasa, kprobe uye kuvhurwa kweiyo kernel munzvimbo yayo (kuuraya munzvimbo, kuuraya kubva kune yepakutanga svikiro, pasina kuteedzera kune RAM).
Mukuwedzera yeanhasi maIntel processors, nyowani kutonhodza controller yakundwa, Pakutanga rutsigiro rwakapihwawo masisitimu matsva emugadziri aya, iyo Alder Lake-S brand (chizvarwa chegumi nembiri).
Panguva ye AMD inosimbisa FreeSync rutsigiro pamusoro peHDMI, rutsigiro rweASSR (Alternative Encoder Mbeu Reset), ioctl kubvunza vhidhiyo encoding uye kududzira kugona, uye modhi CONFIG_DRM_AMD_SECURE_DISPLAY kuona shanduko muzvikwangwani zvichiratidza ruzivo rwakakosha. Tsigiro yeASMM yekuchengetedza magetsi maitiro yakawedzerwa.
Yeimwe shanduko dzinomira yeiyi nyowani vhezheni yeKernel:
- Tsigiro yeSimultaneous Translation (TLB) Yekutarisa Buffer Dump ficha yemamwe madiki ekuita mabhenefiti Chaizvoizvo, Linux 5.13 x86 ndangariro manejimendi basa rinopa mashoma mashandiro ekugadzirisa ayo anonyanya kubatsira muchiedza cheCPU chengetedzo yekudzora yemakore apfuura ichikanganisa TLB.
- Tsigiro ye AMD Zen yeTurbostat.
- Loongson 2K1000 bracket.
- KVM inopa AMD SEV uye Intel SGX zvinowedzera zvevaenzi chaiwo michina.
- Tsigiro yeIntel bhavha yekucherechedzwa yakawedzerwa mukuwedzera kune iripo rutsigiro rwekuparadzanisa kukiya kuona.
KCPUID chishandiso chitsva mumuti kubatsira kumisikidza nyowani x86 processor. - Iyo generic USB inoratidzira mutyairi yakawedzerwa kune setups senge kushandisa Raspberry Pi Zero seadapter adapta.
- Tsigiro ye "Intel DG1 Platform Monitoring Technology" / telemetry chikuva.
- Iyo POWER9 NVLink 2.0 mutyairi yabviswa nekuda kwekushaikwa kweyakavhurika sosi mushandisi rutsigiro.
- Direct Kupa Manager mutyairi inogadziridza.
