Coreboot (yaimbonzi LinuxBIOS) ipurojekiti ine chinangwa chekutsiva isina-yemahara firmware mune yevaridzi BIOS.
Yakaziviswa nguva pfupi yapfuura kuburitswa kweshanduro itsva dzeCoreboot 4.22 uye 4.22.01 izvo zvinosanganisira zvigadziriso zvichangoburwa, kuvandudzwa kwekuchengetedza uye yakawedzera rutsigiro rwehardware kubva mumwedzi mitatu yapfuura.
Zvinonzi kuburitswa kutsva uku ndiyo vhezheni yekupedzisira kushandisa 4.xx incremental version yekupa zita chirongwa, sezvo mushanduro dzinotevera Coreboot ichachinja kuenda kuGore.Mwedzi.Subversion zita chirongwa. Saizvozvo, kuburitswa kunotevera, kwakarongerwa Kukadzi 2024, kuchaverengerwa 24.02.00 uye kana gadziriso kana ramangwana revhezheni 24.02 rikaitwa, kukosha .01, .02, nezvimwe zvichawedzerwa. kune kukosha kwevhezheni yekutanga.
Hunhu hutsva hutsva hweCoreboot 4.22 uye 4.22.01
Mune iyi vhezheni itsva yeCoreboot, ku kuburitsa kutenderera 4.22 kukanganisa kwakasiyana kwakaonekwa haina kutanga paSandybridge/ivybridge mapuratifomu uye izvi chaive chikonzero chekuburitsa vhezheni 4.22.01.
Panyaya yekuvandudzwa kunoitwa, inosimbiswa kuti x86 inotsigira .data chikamu che pre-memory stages, Shanduko iyi inobvumira kushandiswa kwepasi rose tsanangudzo dzekuchinja muC code. Munguva yekurodha block block, data inowedzerwa pakarepo mushure mekodhi uye yozoiswa mu cache uchishandisa Cache-As-RAM (VMA) pfungwa.
MuCoreboot 4.22 yakagadzirirwa masisitimu x86 mune ramstage uye pre-memory nhanho, kuitiswa kwecache rutsigiro yeCBFS faira system inoshandiswa kubata Coreboot zvikamu muFlash. Zvinonzi mamiriro ezvinhu apo imwe romastage ingave yakakosha inosanganisira zvigadziriso nevboot kana imwe modhi, pamwe nemidziyo ine yakaderera boot block saizi kana inononoka boot media (mamwe maARM SoCs). Kuti ugadzirise saizi yecache, PRERAM_CBFS_CACHE_SIZE uye RAMSTAGE_CBFS_CACHE_SIZE maparamita anokurudzirwa.
Imwe shanduko inomira pachena mukuburitswa uku ndeye yekutanga rutsigiro rwe AMD OpenSIL iyo inoshanda neiyo yega referensi chikuva che AMD EPYC 9004 Genoa/Onyx processor uye iyo inofanirwa kutsiva zvachose raibhurari yeAGESA (AMD Generic Encapsulated Software Architecture) mune ramangwana.
Zvakare yakasimudzwa muCoreboot 4.22 itsigiro yekumhanyisa Microsoft Windows pane mamwe Coreboot-based Chromebooks, iyo inofanirwa kunge iri nani, sezvo imwe yekodhi kodhi yakagadziridzwa.
Kudivi rakerutsigiro rwemidziyo mitsva Ivo zvakare kubva kumahwendefa Google ISH, Anraggar, Brox, Chinchou, Ciri, Deku, Deku4ES, Dexi, Dochi, Nokris, Quandiso uye Rex4ES EC. Zvakare, Coreboot 4.22 inowedzera rutsigiro rwebudiriro yeIntel Meteorlake-P, iyo Purism Librem 11 yataurwa pamusoro (pamwe Librem L1UM v2) uye Siemens FA EHL uye Supermicro X11SSW-F.
Yeimwe shanduko izvo zvinomira pachena:
- Coreboot ikozvino inoisawo vBIOS checksum kana ichizadza tafura yeVFCT, seWindows AMD mutyairi anosimbisa cheki ye data yevBIOS.
- An API yakawedzerwa kune gfx kuona kuvepo kwekunze kwekuratidzira pamidziyo ine Intel chips.
- Yakawedzera shanduko kubvumira Windows kumhanya pane mamwe maChromebook ane Coreboot.
- Yakamisikidzwa ACPI tafura chizvarwa chemidziyo yakavakirwa paArM64 dhizaini.
- Tsigiro yakavandudzwa ye ACPI yakatarwa.
- Iyo MRC (memory reference code) gadziriso yeSNB+MRC mabhodhi yakaendeswa kune iyo DeviceTree chimiro.
- General kuchenesa uye reformating.
- Yakagadziriswa SMM get_save_state calculation isiri kushanda apo STM yakagoneswa
Kana iwe uchifarira kuziva zvakawanda nezve iyi vhezheni itsva yeCoreBoot 4.18, unogona kubvunza iwo ruzivo Mune inotevera chinongedzo.
Tora CoreBoot
Chekupedzisira, kune avo vanofarira kugona kuwana iyi nyowani vhezheni yeCoreBoot vanogona kuzviita kubva muchikamu chavo chekurodha pasi, iyo inogona kuwanikwa pawebhusaiti yepamutemo yeprojekti.
Pamusoro peizvozvo mairi ivo vanozokwanisa kuwana zvinyorwa uye rumwe ruzivo nezve chirongwa. Iyo yekubatanidza ndeiyi.
