Linux 5.14 inouya neDPI 400 kutsigira, zvinowedzera EXT4, madhiraivha, KMV nezvimwe

Mushure memwedzi miviri yekuvandudza, Linus Torvalds yakafumura iyo Linux kernel 5.14 kuburitswa uye mune iyi vhezheni nyowani yeshanduko inonyanya kuzivikanwa, semuenzaniso new quotactl_fd () uye memfd_secret () system yekufona, kubvisa ide uye mbichana madhiraivha, nyowani Ini / O wekutanga mutyairi weboka, SCHED_CORE basa rekugadzirisa maitiro, zvivakwa zvekugadzira BPF yakasimbiswa chirongwa chevarongi.

Iyo itsva vhezheni yakagamuchira 15883 gadziriso kubva kune vanogadzira 2002 chigamba saizi: 69MB (shanduko dzakabata mafaira 12,580, 861501 mitsara yekodhi yakawedzerwa, mitsara 321,654 XNUMX yakabviswa).

Main nyowani maficha eLinux 5.14

Mune iyi vhezheni itsva a nyowani I / O kuisa pamberi mutyairi weboka -rq-qos, Inogona chengetedza kukosha kwekugadzirisa zvikumbiro zvekuvharira zvishandiso inogadzirwa nenhengo dzeboka rega rega. Tsigiro yemutungamiriri mutsva wekutanga yakawedzerwa kune mq-nguva yakatarwa I / O scheduler.

Imwe shanduko yakakosha iri mu ext4, iyo ikozvino inoshandisa nyowani EXT4_IOC_CHECKPOINT ioctl rairo iyo inomanikidza zvese zvakamirira zvinyorwa zvejenari uye mabhaidhi avo anowirirana kuti atorwe kudisk, uyezve anonyora nzvimbo yekuchengetera inoshandiswa nejenali. Shanduko yakagadzirirwa sechikamu chekutanga chekudzivirira kuburitsa kweruzivo kubva kumafaira masystem. Mukuwedzera optimization yekuita yakaitwa kuBtrfs nekubvisa kuburitswa kweasina kufanira kuwedzerwa hunhu panguva yekuitwa kwefsync, mashandiro ekushanda kwakasimba nehunhu hwakawedzerwa kusvika ku17%.

Pane rimwe divi akawedzera quotactl_fd () system yekufona, iyo inobvumidza iwe kubata makota kwete kuburikidza neakasarudzika faira faira, asi nekutsanangudza iyo faira dudziro inosanganisirwa neiyo faira system iyo iyo quota inoiswa.

Mukuwedzera madhiraivha ekare emidziyo yekuvharira neiyo interface yeIDE abviswa kubva kune kernel, iyo yakagara ichisimudzwa neiyo libata subsystem. Rutsigiro rwezvigadzirwa zvekare rwachengetedzwa zvizere, shanduko dzinongoreva mukana wekushandisa madhiraivha ekare, kana uchishandisa madhiraivha ayo akanzi / dev / hd *, kwete / dev / sd *.

Basa Rinoronga rine itsva SCHED_CORE kuronga nzira , que inokutendera iwe kudzora kuti ndeapi maitiro anogona kumhanya pamwechete pane imwechete CPU musimboti. Maitiro ega ega anogona kupihwa kodhi yekuziva iyo inotsanangura chiyero chekuvimba pakati pezvakaitwa (semuenzaniso, zvemumwe mushandisi kana mudziyo).

Iyo memfd_secret () system yekufona yawedzerwaque inokutendera kuti iwe ugadzire yakavanzika nzvimbo yekurangarira munzvimbo yekero yakasarudzika, inoonekwa chete kune muridzi maitiro, isingaratidzwe mune mamwe maitiro, uye isinganetsi kusvika kune kernel.

Iye hypervisor KVM yeARM64 masisitimu akawedzera kugona kushandisa iyo MTE yekuwedzera pamasisitimu evaenzi, ichikubvumidza iwe kusunga mateki kune yega yekugovanisa ndangariro mashandiro uye kuronga ongororo yekushandisa chaiko kwekunongedzera kuvharira kushandiswa kwekusasimba inokonzereswa neakawana atosunungurwa mabhureki endangariro, buffer inopfachukira, mafoni asati atanga, uye shandisa kunze kwechimiro chiripo.

Pointer kusimbiswa kunopihwa neARM64 ikozvino inogona kugadzirirwa zvakasiyana kune kernel uye mushandisi nzvimbo. Iyo tekinoroji inobvumidza kushandiswa kwehunyanzvi ARM64 mirairo yekuona kudzoka kero uchishandisa masiginecha edhijitari, ayo anochengetwa mune asina kushandiswa epamusoro mabhii eiyo pointer pachayo.

YeIntel CPUs, kutanga nemhuri yeSkylake uye kupera neCofi Lake, uchishandisa Intel TSX (Transactional Kubvumirana Kuwedzeredzwa) yakaremara nekutadza, iyo inopa nzira yekuvandudza mashandisirwo ezvinyorwa zvakaverengeka nekubvisa zvine simba mashandiro asina kufanira ekuwiriranisa. Iwo ekuwedzeredzwa akaremara nekuda kwekugona kwekuita Zombieload kurwisa.

Tambien ramba uchienderera mberi nekubatanidzwa kweMPTCP (MultiPathTCP), mushanduro nyowani, michina yakawedzerwa kumisikidza yako wega traffic hash marongero ePv4 neIPv6, izvo zvinoita kuti zvive nyore kubva kune mushandisi nzvimbo kuona kuti ndeapi epakeji minda, kusanganisira akavharirwa, anozoshandiswa pakuverenga hashi inosarudza sarudzo yemugwagwa wepaketi.

Mutungamiriri amdgpu yakatsigira rutsigiro rweiyo nyowani AMD Radeon RX 6000 nhevedzano yeGPU, yakagadzirirwa pasi pemazita emakodhi "Beige Goby" (Navi 24) uye "Yero Carp", pamwe nekutsigirwa kwakatsigirwa kweGPU Aldebaran (gfx90a) uye APU Van Gogh. Wakawedzera kugona kushanda nemazhinji eDP mapaneru panguva imwe chete.

Para Renoir APU, rutsigiro rwekushanda nemabhaudhi akavharidzirwa muvhidhiyo memory inoitwa, Panguva yeiyo yapfuura Radeon RX 6000 (Navi 2x) uye AMD GPUs, Active State Power Management (ASPM) rutsigiro inogoneswa nekutadza, iyo yaimbove inogoneswa chete kuna Navi 1x, Vega, uye Polaris GPUs.

Zve AMD machipisi, rutsigiro rwekugovana virtual memory rwakawedzerwa (SVM) yakavakirwa paiyo Heterogeneous Memory Management Subsystem (HMM), iyo inogonesa michina ine yavo yekumusoro manejimendi mayunitsi (MMUs) kuti ishandiswe, iyo inogona kuwana main memory. Kunyangwe nerubatsiro rweHMM, unogona kuronga nzvimbo yekubatanidza kero pakati peGPU neCUU, umo iyo GPU inokwanisa kuwana ndangariro huru yeichi chiitiko.

Pane dzimwe shanduko dzinobuda pachena:

• Pakutanga rutsigiro rwakawedzerwa kune AMD Smart Shift tekinoroji, iyo inoshandura zvine simba CPU neGPU simba rekushandisa mumalaptop ane AMD chipset uye kadhi yemifananidzo kuvandudza mashandiro mumitambo, kugadzirisa vhidhiyo, uye 3D kupa.
• Wakawedzera simpledrm giraidhi mutyairi uchishandisa EFI-GOP kana VESA furemu yebuffer yakapihwa neEFI firmware kana BIOS yekubuditsa.
• Wakawedzera rutsigiro rweRaspberry Pi 400.
• YeLenovo laptops, iyo WMI interface yakawedzerwa kushandura marongero eBIOS kuburikidza / sys / kirasi / firmware-hunhu /.
• Yakawedzerwa rutsigiro rwe USB4.
