Emva kweenyanga ezimbini zophuhliso, ULinus Torvalds watyhilwa kwiintsuku ezimbalwa ezidlulileyo ukuqaliswa kwekwinguqulo entsha ye-Linux kernel 5.17.
Phakathi kweenguqu eziphawulekayo iqaqambisa inkqubo entsha yolawulo lwentsebenzo ye Iiprosesa AMD, inkxaso yeenkqubo zeBPF iilaptops ezihlanganisiweyo, utshintsho ukusuka kwi-pseudo-random number generator ukuya kwi-BLAKE2s algorithm, fscache yangasemva entsha Ukugcina inkqubo yefayile yomsebenzi womnatha, phakathi kwezinye izinto.
Inguqulelo entsha ifumene ukulungiswa kwe-14203 kubaphuhlisi be-1995, ubungakanani bepatch yi-37 MB (utshintsho oluchaphazelekayo lweefayile ze-11366, imigca ye-506043 yekhowudi yongezwa, imigca ye-250954 isusiwe).
Eyona nto iphambili kwiLinux Kernel 5.17
Kule nguqulo intsha ukuba nokwenzeka kokwenziwa kweemephu ezibekwe kwindlwane yee-ID zabasebenzisi beenkqubo zefayile ezinyusiweyo ziphunyeziwe, esetyenziselwa ukwenza imephu iifayile zomsebenzisi othile kwisahlulelo sangaphandle exhonywe nomnye umsebenzisi kwinkqubo yangoku. Uphawu olongeziweyo lukuvumela ukuba usebenzise imephu ngokuphindaphindiweyo kwiinkqubo zefayile apho imephu sele isetyenzisiwe.
Inkqubo esezantsi fscache ibhalwe ngokutsha ngokupheleleyo. Ukuphunyezwa okutsha yahlulwa ngokwenziwa lula okubalulekileyo kwekhowudi kunye nokutshintshwa kwenkqubo entsonkothileyo kunye nemisebenzi yokulandela umkhondo wemeko ngeendlela ezilula. Inkxaso yefscache entsha iphunyezwe kwinkqubo yefayile yeCIFS.
I-Btrfs ilungiselelwe imisebenzi yokubhalisa kunye ne-fsync kubalawuli abakhulu, baphunyezwe ngokukopa kuphela izitshixo zesalathiso kunye nokunciphisa inani lemetadata erekhodiweyo, kunye nokukhangela kunye nokukhangela ngenkxaso yobungakanani besithuba esikhululekileyo sinikezelwe, ukuncitshiswa kwe-latency kunye nexesha lokufuna malunga ne-30%, eyavumela ukuba imisebenzi yokuqhawula iphazamiseke.
I-Ext4 ifudukele kwindawo entsha ye-API esahlula izigaba zokwahlulahlula iinketho zentaba kunye nokuqwalasela i-superblock, kunye nenkxaso ye-lazytime kunye ne-nolazytime yokunyuka kweenketho zasuswa, ezongezwa njengotshintsho lwexeshana ukuze kube lula ukuguquka ukusuka kwi-util-linux ukuya ekusebenziseni iflegi MS_LAZYTIME kunye inkxaso eyongeziweyo yokuseta nokufunda iithegi kwiFS (ioctl FS_IOC_GETFSLABEL kunye FS_IOC_SETFSLABEL).
Umlawuli i-amd-pstate yongezwe ukubonelela ngolawulo oluguquguqukayo lwamaza ukusebenza ngokugqibeleleyo. Umqhubi uxhasa ii-CPU ezintsha ze-AMD kunye nee-APU, kuquka ezinye ze-Zen 2 kunye ne-Zen 3 ze-chips zesizukulwana, kwaye yaphuhliswa ngokubambisana neValve ukuphucula ulawulo lwamandla olusebenzayo. Ukutshintshela i-frequency switching, i-CPPC (i-Collaborative Processor Performance Control) isetyenzisiwe, ekuvumela ukuba utshintshe izikhombisi ngokuchanekileyo (izingaphelelanga kumanqanaba amathathu okusebenza) kwaye uphendule ngokukhawuleza kwiinguqu kwimeko kune-P-state esetyenziswe ngaphambili kwi-ACPI. abaqhubi. (i-CPU frequency).
Kwelinye icala, kuyacaciswa ukuba umiliselo oluhlaziyiweyo luyandululwa ukusuka kwi-pseudorandom number generator RDRAND, ojongene nokusebenza kwezixhobo / dev / random kunye / dev / urandom, ephawulekayo kwinguqu ekusebenziseni i-BLAKE2s umsebenzi we-hash endaweni ye-SHA1 kwimisebenzi yokuxuba i-entropy. Utshintsho lwenza ukuba kube lula ukunyusa ukhuseleko lwe-pseudo-random number generator ngokususa i-algorithm ye-SHA1 enzima kunye nokususa ukubhala ngaphezulu kwe-RNG yokuqalisa i-vector. Ekubeni i-algorithm ye-BLAKE2s iphambi kwe-SHA1 ngokwemigaqo yokusebenza, ukusetyenziswa kwayo kube nefuthe elihle ekusebenzeni.
Yongezwe ukhuseleko ngokuchasene nobuthathaka beprosesa obangelwa kukubulawa okuqikelelwayo yemiyalelo emva kwemisebenzi yokutsibela phambili ngaphandle kwemiqathango. Ingxaki ivela kulungiselelo lwangaphambili lwemiyalelo ngokukhawuleza emva komyalelo wokutsiba kwimemori (i-SLS, i-Straight Line Speculation). Ukunika amandla ukhuseleko kufuna ulwakhiwo nge-GCC inguqulo ye-12, ekuvavanyo ngoku.
Inkqubo esezantsi Idrm (UMlawuli oBonelela ngokuthe ngqo) kunye nomqhubi we-i915 wongeze inkxaso kwizikrini ukubonisa ulwazi olubuthathaka, umzekelo, ezinye iilaptops zixhotyiswe ngezikrini ezinemowudi yokuJonga iMfihlo eyakhelweyo, eyenza kube nzima ukujonga ngaphandle. Utshintsho olongeziweyo lukuvumela ukuba uqhagamshele kubaqhubi abakhethekileyo kwizikrini ezinjalo kwaye ulawule iindlela zokukhangela zabucala ngokuseta iipropathi kubaqhubi abaqhelekileyo be-KMS.
Umlawuli i-amdgpu ibandakanya inkxaso yetekhnoloji yokulungisa i-STB (I-Smart Trace Buffer) yazo zonke ii-AMD GPU ezixhasayo. I-STB iququzelela uhlalutyo lokungaphumeleli kwaye ichonge umthombo weengxaki ngokugcina ulwazi olukhethekileyo lwe-buffer malunga nemisebenzi eyenziwa phambi kokusilela kokugqibela.
Olunye utshintsho olwahlukileyo:
- Umqhubi we-i915 wongeza inkxaso yeetshiphusi ze-Intel Raptor Lake S kwaye unika inkxaso kwimizobo ye-Intel Alder Lake P ngokungagqibekanga.
- Abaqhubi be-fbcon/fbdev babuyise inkxaso yokuskrola okukhawulezileyo kwehardware kwi-console.
- Ukuhlanganiswa okuqhubekayo kweenguqu zokuxhasa i-Apple M1 chips.
- Iphunyezwe amandla okusebenzisa umqhubi we-simpledrm kwiinkqubo ezine-Apple M1 chip ukuvelisa imveliso nge-firmware enikezelweyo yefreyim buffer.
- bpf_loop() isibambi kwisistim esezantsi ye-eBPF, ebonelela ngenye indlela yokulungelelanisa iilophu kwiiprogram ze-eBPF, ngokukhawuleza nalula ukuba umqinisekisi aqinisekise.
Ukuba ukhona unomdla wokwazi ngakumbi ngayo, ungajonga iinkcukacha Kule khonkco ilandelayo.
