Linus Torvalds da aka fitar a wannan Lahadi, sigar 5.2 ta Linux Kernel, bayan RCs bakwai (ɗan takarar sakewa). Sabuwar sigar Kernel ba reshe bane na LTS (Taimako na Tsawon Lokaci), wanda ke nufin cewa masu amfani da yawa na iya fifita kiyaye sigar ta LTS.
Linux 5.2 ya zo tare da Sound Open Firmware, wata babbar hanyar firmware wacce ke tallafawa na'urorin audio na DSP, sabon API mai gyara don hawa tsarin fayiloli, sabon matattarar buɗe GPU direbobi don na'urorin ARM Mali da sauran abubuwan haɓakawa da yawa.
Da farko, Torvalds ya ce a shirye yake ya ci gaba da wani mako na RC, amma jerin abubuwan da suka faru sun tilasta shi.
A ƙarshe ya yanke shawarar buga kernel kamar yadda yake, bayan RCs bakwai.
“Na ɗan yi ɗoki ga rc8, kawai saboda tafiye-tafiye na da kuma rashin kasancewa gaba ɗaya daga intanet makon da ya gabata. Don haka kodayake kwaya ya dawo da latti, ban ga wani dalili mai ma'ana ba na wani mako na rc, saboda haka muna da sigar 5.2 tare da lokacin saki na yau da kullun, 'an bar shi a matsayin saƙo a jerin Kernel Broadcast Broadcast. Linux 5.2 yanzu yana nan kuma yana ba da fasali da haɓakawa don mafi ban sha'awa.
Babban sabon labari na Kernel 5.2
Nau'in 5.2 na Linux Kernel ya fita waje don bayarwa aikin da yake yi sa yanayin fayil ɗin EXT4 ya zama mara hankali, da goyon baya ga Intel Open Firmware, Direbobin hoto na ARM Mali tare da Lima da Panfrost, sabon mai sarrafa Realtek WiFi don maye gurbin mai sarrafa RTLWIFI na yanzu, sababbin tsarin tsarin filin wasa da ƙididdigar jigilar abubuwa, da dai sauransu.
Wannan sigar ta inganta ingantaccen bayanan abubuwan matsi don amfani da Android. Hakanan akwai tallafi ga samfuran Intel masu yawa, kuma an sake tsara API mai gyara tare da sabon kiran tsarin.
Bude sauti
Duk da yake da yawa na'urorin audio na DSP suna da matukan buɗe ido, firmware dinka ya kasance a rufe kuma an kawo shi azaman fayilolin binary.
Sakamakon haka, matsalolin firmware galibi suna da wahalar warwarewa. Wannan aikin Bude Firmware (SOF), goyan bayan Intel da Google, an ƙirƙira shi don inganta wannan yanayin ta hanyar samar da dandamali mai buɗewa don ƙirƙirar firmware mai buɗewa don sautin DSP.
Fayilolin SOF ba kawai za su ba masu amfani damar samun firmware mai buɗewa ba, amma kuma ba su damar tsara nasu firmware. Layin Linux na 5.2 ya haɗa da SOF kernel da Intel Open Source firmware don yawancin manyan kayan sa: Baytrail, CherryTrail, Broadwell, ApolloLake, GeminiLake, CannonLake da IceLake.
Ingantawa zuwa EXT4
Tun halittarta, Linux ya kasance mai saurin damuwa. Koyaya, cA kan sigar 5.2, tsarin fayil na EXT4 zai ba da izini fayil da kuma goyon bayan babban fayil wannan ba matsala bane.
Waɗannan gyaran sun kasance suna cikin ci gaba na dogon lokaci, amma a ƙarshe sun kasance a shirye don tallafi na al'ada. Farawa tare da sigar 5.2, kernel na Linux yanzu yana ƙara sabon fasali zuwa tsarin fayil na ETX4 wanda ba shi da matsala.
Protectionarin kariya game da kurakuran CPU da zaɓin tayaƙa
Wannan fitowar yana ƙara tsarin bug don ɗaukar raunin kayan aikin Microarchitecture Data Sampling (MDS) wanda ke ba da damar samun damar keɓaɓɓen damar samun bayanan da ke cikin ɗakunan CPU na ciki.
Wannan sabon saitin lahani yana da nau'uka da yawa. Domin taimakawa masu amfani da shi wajen magance yawan kurakuran masu sarrafawa tsakanin gine-gine daban-daban, an kara sabon zabin taya mai zaman kansa mai suna "mitigations ="
Wannan saiti ne na keɓaɓɓu da zaɓuɓɓukan baka (a halin yanzu x86, PowerPC, da s390) don sauƙaƙe don kunna ko musaki kariya ba tare da la'akari da tsarin da suke ciki ba. 'a jere.
Kernel na Linux 5.2 kuma ya haɗa da sababbin sabbin direbobi da sabunta don ingantaccen kayan aiki, kazalika da gyaran kura-kuran da ba za a iya kirgawa da gyaran tsaro ba.
Sabuwar sigar kwayar Linux, ta 5.2, ta ƙunshi direbobi biyu na al'umma don masu haɓaka ARM Mali.
