Emva kweenyanga ezimbini zophuhliso, ILinus Torvalds ityhilile ukukhutshwa kweLinux kernel 5.14 kwaye kule nguqulelo intsha yotshintsho olubalulekileyo, umzekelo entsha quotactl_fd () kunye memfd_secret () iifowuni, ukususa i-ide kunye nabaqhubi abaluhlaza, intsha Umqhubi ophambili we-I / O weqela, SCHED_CORE imo yokucwangciswa kwemisebenzi, iziseko zophuhliso zenkqubo ye-BPF eqinisekisiweyo.
Inguqulelo entsha ifumene izilungiso ezili-15883 ezivela kubaphuhlisi Ubungakanani bepatch ka-2002: 69MB (utshintsho oluchaphazele iifayile ze-12,580, Imigca engama-861501 yekhowudi yongezwa, 321,654 imigca isuswe).
Iimpawu ezintsha eziphambili zeLinux 5.14
Kule nguqulo intsha a umqhubi omtsha we-I / O wokubeka phambili kwiqela -rq-qos, Enako lawula ukubaluleka kokuqhubekeka kwezicelo zokuthintela izixhobo eziveliswe ngamalungu eqela ngalinye. Inkxaso yomlawuli omtsha ophambili kuye kwongezwa kumcwangcisi we-I / O we-mq-wokugqibela.
Olunye utshintsho olubalulekileyo ku ext4, Ngoku isebenzisa umyalelo omtsha we-EXT4_IOC_CHECKPOINT ioctl enyanzela yonke intengiselwano yejenali esalindelweyo kunye neetabha ezinxulumene noko ukuba zikhutshelwe kwidiski, kwaye iphinde ibhale ngaphezulu indawo yokugcina esetyenziswe lishicilelo. Utshintsho yayilungiselelwe njengenxalenye yephulo lokuthintela ukuvuza kolwazi kwiinkqubo zefayile. Kwakhona ukwenziwa komsebenzi kwenziwe kwiBtrfs xa ucima ushicilelo lweempawu ezingafunekiyo ngexesha lokuqhutywa kwe-fsync, ukusebenza kwemisebenzi ebanzi enezimpawu ezandisiweyo kuye kwanda ukuya kwi-17%.
Kwelinye icala yongeza i-quotactl_fd () inkqubo yomnxeba, ekuvumela ukuba ulawule izabelo hayi kwifayile yesixhobo esikhethekileyo, kodwa ngokuchaza inkcazo yefayile enxulunyaniswa nenkqubo yefayile esetyenziselwa yona isabelo.
Kwakhona Abaqhubi abadala bezixhobo zebhloko kunye ne-IDE interface basusiwe kwikernel, ekudala zithathelwe indawo yinkqubo esezantsi ye-libata. Inkxaso yezixhobo ezindala igcinwe iyonke, utshintsho lubhekisa kuphela kwimeko yokusebenzisa iidrives ezindala, xa usebenzisa iidrives ezazinegama / dev / hd *, hayi / dev / sd *.
Isicwangcisi somSebenzi sinendlela entsha yokucwangcisa ye-SCHED_CORE que ikuvumela ukuba ulawule ukuba zeziphi iinkqubo ezinokuqhuba kunye kwisiseko esinye se-CPU. Inkqubo nganye inokunikezelwa ngecookie yokuchonga echaza ubungakanani bokuthenjwa phakathi kweenkqubo (umzekelo, ezomsebenzisi omnye okanye isikhongozeli).
Inkqubo ye memfd_secret () yongezwa, que ikuvumela ukuba wenze indawo yememori yabucala kwindawo yedilesi iyodwa, ibonakala kuphela kwinkqubo yokuthengisa, ayiboniswanga kwezinye iinkqubo, kwaye ayifikeleleki ngqo kwi-kernel.
Isiphathamandla Iinkqubo ze-KVM ze-ARM64 zongeze amandla okusebenzisa ulwandiso lwe-MTE kwiinkqubo zeendwendwe, ezikuvumela ukuba ubophe iithegi ekusebenzeni kwememori nganye kwaye uququzelele itsheki Usetyenziso oluchanekileyo lwezikhombisi ukuvimba ukuxhaphaza ubungozi kubangelwe kukufikelela kwiibhloko esele zikhululwe zememori, ukugcwala kwempazamo, iifowuni ngaphambi kokuqalisa, kunye nokusebenzisa ngaphandle komxholo wangoku.
Ubungqina besikhombisi bunikezelwa yi-ARM64 ngoku inokuqwalaselwa ngokwahlukeneyo kwindawo yekernel kunye neyomsebenzisi. Itekhnoloji ivumela ukusetyenziswa kwemiyalelo ekhethekileyo ye-ARM64 yokuqinisekisa iidilesi zokubuyisa zisebenzisa iisiginitsha zedijithali, ezigcinwe kwiibhithi ezingasetyenziswanga eziphezulu zesikhombisi uqobo.
Kwii-Intel CPUs, ukuqala nosapho lwaseSkylake kwaye uphele ngeCofi Lake, usebenzisa i-Intel TSX (Ukwandiswa kokuNxibelelanisa okwenziweyo) ikhubazekile ngokungagqibekanga, Oku kubonelela ngeendlela zokuphucula ukusebenza kwezicelo ezifundwayo ngokususa ngamandla imisebenzi yokuvumelanisa. Izandiso zikhubazekile ngenxa yokwenzeka kokwenza uhlaselo lweZombieload.
Tambien qhubeka nokudityaniswa kwe-MPTCP (MultiPathTCP), Kwinguqulelo entsha, umatshini wongezwe ukuseta eyakho imigaqo-nkqubo ye-hash ye-IPv4 kunye ne-IPv6.
Umlawuli I-amdgpu isebenzise inkxaso ye-AMD Radeon RX 6000 uthotho lwee-GPU, iphuhliswe phantsi kwamagama ekhowudi "Beige Goby" (Navi 24) kunye "neYellow Carp", kunye nenkxaso ephuculweyo yeGPU Aldebaran (gfx90a) kunye neAPU Van Gogh. Yongeze amandla okusebenza ngeepaneli ezininzi ze-eDP ngaxeshanye.
ukuba I-APU Renoir, inkxaso yokusebenza kunye ne-encrypted buffers kwimemori yevidiyo iyaphunyezwa, Ngelixa i-Radeon RX 6000 yangaphambili (i-Navi 2x) kunye ne-AMD GPUs, i-Active State Power Management (ASPM) inkxaso inikwe amandla ngokungagqibekanga, ngaphambili eyayivunyelwe kuphela kwiNavi 1x, Vega, kunye nePolaris GPUs.
Iitshipsi ze-AMD, inkxaso yememori ekwabelwana ngayo yongezwa (SVM) esekwe kwi-Heterogeneous Memory Management Subsystem (HMM), eyenza ukuba izixhobo ezinolawulo lwazo lweememori (ii-MMUs) zisetyenziswe, ezinokufikelela kwimemori ephambili. Ngaphandle koncedo lwe-HMM, unokucwangcisa indawo edibeneyo yedilesi phakathi kwe-GPU kunye ne-CPU, apho i-GPU inokufikelela kwimemori ephambili yenkqubo.
Olunye utshintsho olwahlukileyo:
- Inkxaso yokuqala yongezwa kubuchwephesha be-AMD Smart Shift, etshintsha ngamandla i-CPU kunye nokusetyenziswa kwamandla kwi-laptops nge-chipset ye-AMD kunye nekhadi lemizobo ukuphucula ukusebenza kwimidlalo, ukuhlela ividiyo kunye nokunikezelwa kwe3D.
- Kongezwe isilawuli semizobo ye-simpledrm usebenzisa i-EFI-GOP okanye i-VESA framebuffer ebonelelwe yi-UEFI firmware okanye i-BIOS yemveliso.
- Yongeze inkxaso yeRaspberry Pi 400.
- Kwiilaptops zeLenovo, ujongano lweWMI lwongezwa ukutshintsha useto lweBIOS nge / sys / class / firmware-attribute /.
- Inkxaso eyandisiweyo ye-USB4.
Isishwankathelo esihle seendaba endizifundileyo kwi-Hispanic blogosphere, epheleleyo, ecacisayo kunye neenkcukacha ngaphandle kokudinwa. Ke kufuneka kusoloko kunjalo. Enkosi!
