I-Libreboot ihlose ukudala indawo yesistimu ekhipha ngokuphelele isoftware yokuphathelene
Kukhishwe inguqulo ye-Libreboot boot firmware 20230625, inguqulo lapho kulungiswe iziphazamisi eziningi, kanye nalokho kusekelwa kwamabhodi amasha namadivayisi ahlukahlukene kwengeziwe naphezu kokuba inguqulo yokulungisa.
Kulabo abangajwayele i-Libreboot, kufanele bazi ukuthi lokhu iphrojekthi eyenza imfoloko yamahhala yephrojekthi ye-CoreBoot, ehlinzeka ngokushintshwa kwamahhala kanambambili kwe-UEFI yobunikazi kanye ne-BIOS firmware enesibopho sokuqalisa i-CPU, inkumbulo, ama-peripheral, nezinye izingxenye zehadiwe.
libreboot inikeza i-firmware esebenzayo yemishini ye-x86/ARM ehambisanayo, ukuqala i-bootloader ebese ilayisha uhlelo lwakho lokusebenza. Ingena esikhundleni se-firmware ye-BIOS/UEFI emishinini ye-x86 futhi inikeza ukucushwa kuthuthukisiwe kuma-Chromebook asekelwe ku-ARM asekelwe (i-U-Boot bootloader, esikhundleni se-Google yokulayisha umthwalo ojulile).
Emishinini ye-x86, i-GRUB kanye ne-SeaBIOS coreboot payloads kusekelwa ngokusemthethweni futhi kunikezwa ngokulungiselelwa okuhlukile ngomshini ngamunye. Ungathola uhlu lwehadiwe ehambisanayo kumadokhumenti e-Libreboot.
Izindaba eziyinhloko ze-Libreboot 20230625
Kule nguqulo entsha ye-Libreboot 20230625 eyethulwe, kugqanyiswe lokho Kwenziwe umsebenzi wokuthuthukisa ukuzinza futhi ulungise iziphazamisi lapho usebenza namabhodi ahambisanayo ngaphambilini.
Olunye ushintsho olugqamile kule nguqulo entsha ukuthi ihlanganise yonke imibhalo kumkhombandlela oyinhloko we-lbmk (isistimu yokwakha). Wonke ama-core logic manje ayisikripthi esisodwa, esisusa ukuphindaphinda kwekhodi okungadingekile, kanye nombhalo wosizo ususiwe emibhalweni ethile.
Ngaphezu kwalokhu, kubuye kugqanyiswe ukuthi manje Izinsiza ze-coreboot ziqine kakhulu, kanye nokulungisa iphutha lapho izinsiza ziphinde zahlanganiswa ngokungadingekile, kwehliswe ukudalwa kwezithombe eziningi.
I- uhlelo olusha lwe-"spkmodem_recvim" ikhasi langaphambili le-coreboot, okwathi ekuqaleni yayifohloza isuka ku-GNU GRUB. Lokhu iklayenti lokwamukela le-spkmodem, uhlobo lwe-serial console elethwa ngama-pulses ngesipika se-PC. Inguqulo ye-Libreboot ithuthukisa kakhulu ukuphathwa kwamaphutha, futhi iklanyelwe kabusha isitayela sekhodi se-OpenBSD, ukuze singene esikhundleni sesitayela sokubhala se-GNU.
Ngakolunye uhlangothi, kuqokonyiswa lokho usayizi welogo yokuqalisa wehliselwe ku-~3KB, kuze kufike ku-~12KB, okwenziwa, ngaphandle kokulahlekelwa ikhwalithi yesithombe.
Ngokuqondene ne ukulungiswa kwamaphutha izimbungulu ezingaphakathi kwamagobolondo angaphansi ziyagqanyiswa, kanye nokukhulisa usayizi webhafa eguquguqukayo ye-EFI ukuze kulungiswe iphutha lapho i-shim esayiniwe ye-Debian yabela okuguquguqukayo okuningi kwe-EFI ukuze kungene esikhaleni esinikeziwe, kwephula inqubo yokwakha.
Ngaphezu kwalokho izithombe ezizenzakalelayo ezifaka i-firmware ye-x86 CPU, kunezinye izithombe eziza ngaphandle kwe-firmware.
Ngu ingxenye yokuthuthukiswa kosekelo, Amadivayisi alandelayo agqanyisiwe futhi manje ayasekelwa kulokhu kukhishwa okusha:
