O projeto desenvolve uma vers\u00e3o do projeto coreboot, fornecendo uma alternativa aos firmwares propriet\u00e1rios UEFI e BIOS, respons\u00e1veis pela inicializa\u00e7\u00e3o da CPU, mem\u00f3ria, dispositivos perif\u00e9ricos e outros componentes de hardware, minimizando inser\u00e7\u00f5es bin\u00e1rias.      <\/p>\n<p>O Libreboot visa formar um ambiente de sistema que permite a total depend\u00eancia de software livre, n\u00e3o apenas no n\u00edvel do sistema operacional, mas tamb\u00e9m em firmwares que garantem a inicializa\u00e7\u00e3o. O Libreboot n\u00e3o apenas limpa o coreboot de componentes n\u00e3o livres, mas tamb\u00e9m o complementa com ferramentas para facilitar o uso por parte de usu\u00e1rios finais, formando uma distribui\u00e7\u00e3o que qualquer usu\u00e1rio sem habilidades especiais pode aproveitar.       <\/p>\n<p>Entre os equipamentos suportados pelo Libreboot:  <\/p>\n<ul>\n<li class=\"l\"> Sistemas desktop: Gigabyte GA-G41M-ES2L, Intel D510MO, Intel D410PT, Intel D945GCLF e Apple iMac 5,2.  <\/li>\n<li class=\"l\"> Notebooks: ThinkPad X60 \/ X60S \/ X60 Tablet, ThinkPad T60, Lenovo ThinkPad X200 \/ X200S \/ X200 Tablet \/ X220 \/ X230, Lenovo ThinkPad R400, Lenovo ThinkPad T400 \/ T400S \/ T420 \/ T440, Lenovo ThinkPad T500 \/ T530, Lenovo ThinkPad W500 \/ W530, Lenovo ThinkPad R500, Apple MacBook1 e MacBook2, bem como v\u00e1rios dispositivos Chromebook das empresas ASUS, Samsung, Acer e HP.  <\/li>\n<\/ul>\n<p>No novo lan\u00e7amento:  <\/p>\n<ul>\n<li class=\"l\"> Suporte para notebooks Lenovo ThinkPad W530 e T530 foi adicionado. Na pr\u00f3xima vers\u00e3o, espera-se suporte para HP EliteBook 8560w, Lenovo G505S e Dell Latitude E6400.\n<li class=\"l\"> O suporte para placas Asus p2b_ls e p3b_f foi encerrado.\n<li class=\"l\"> O c\u00f3digo para inicializa\u00e7\u00e3o de mem\u00f3ria (raminit) foi adaptado para placas com processadores baseados na microarquitetura Haswell. O funcionamento foi testado nos notebooks ThinkPad T440p e ThinkPad W541.\n<li class=\"l\"> Foram resolvidos problemas com a transi\u00e7\u00e3o para o modo de suspens\u00e3o (S3) nos notebooks ThinkPad T440p e ThinkPad W541.\n<li class=\"l\"> No GRUB, foi ativado o modo for\u00e7ado de sa\u00edda para o console (GRUB_TERMINAL=console) sem alterar o modo de v\u00eddeo, o que melhorou a exibi\u00e7\u00e3o dos menus de inicializa\u00e7\u00e3o de alguns distribui\u00e7\u00f5es Linux.\n<li class=\"l\"> Para a maioria das placas x86, foi feita a sincroniza\u00e7\u00e3o com a base de c\u00f3digo do CoreBoot de fevereiro de 2023, incluindo melhorias para dispositivos com chips baseados na microarquitetura Haswell (ThinkPad T440p \/ W541).\n<li class=\"l\"> As altera\u00e7\u00f5es foram transferidas a partir das bases de c\u00f3digo atuais do GRUB e SeaBIOS.\n<li class=\"l\"> O tempo de espera em grub.cfg foi reduzido de 10 para 5 segundos.\n<li class=\"l\"> Para notebooks ThinkPad GM45, o tamanho da mem\u00f3ria de v\u00eddeo alocada por padr\u00e3o foi reduzido de 352MB para 256MB.\n<li class=\"l\"> A base de c\u00f3digo do nvmutil foi reestruturada.  <\/ul>\n<p>Al\u00e9m disso, o autor do Libreboot come\u00e7ou a desenvolver uma nova distribui\u00e7\u00e3o Live minimalista para a recupera\u00e7\u00e3o de sistemas ap\u00f3s falhas. Semelhante \u00e0 distribui\u00e7\u00e3o Heads, o projeto desenvolve um ambiente de sistema reduzido que pode ser carregado a partir do LibreBoot, CoreBoot ou LinuxBoot. No entanto, em vez de ser montado como um \"payload\" de inicializa\u00e7\u00e3o, o novo projeto pretende preparar uma imagem do sistema separada, carregada no CBFS e chamada a partir de payloads intermedi\u00e1rios com GRUB ou SeaBIOS, capazes de executar arquivos execut\u00e1veis armazenados no Flash.        <\/p>\n<p>O projeto \u00e9 interessante porque visa combinar o kernel Linux, a biblioteca padr\u00e3o C Musl e as ferramentas do ambiente b\u00e1sico OpenBSD. Para implementar essa ideia, o desenvolvimento do projeto lobase, que se ocupou do porting de utilit\u00e1rios OpenBSD para Linux, mas foi abandonado h\u00e1 5 anos (o autor do Libreboot criou um fork do lobase, que foi atualizado para o OpenBSD 7.2 e portado para Musl), foi continuado. Para gerenciamento de pacotes e instala\u00e7\u00e3o de programas adicionais, est\u00e1 previsto o uso da ferramenta apk-tools do Alpine Linux, e para a forma\u00e7\u00e3o de imagens, as ferramentas de constru\u00e7\u00e3o abuild e aports. Ap\u00f3s a conclus\u00e3o do fork do ambiente de usu\u00e1rio OpenBSD, est\u00e1 previsto que ele seja transferido para o projeto Alpine para ser usado como uma alternativa ao pacote BusyBox.    <\/p>\n<p>Al\u00e9m disso, pode-se destacar o an\u00fancio do projeto CloudFW 2.0 com a implementa\u00e7\u00e3o de firmware baseado em Coreboot e LinuxBoot para substituir o UEFI, fornecendo uma pilha de firmware totalmente aberta para x86.<a class=\"wpil_keyword_link\" href=\"https:\/\/prohoster.info\/pt\/server\/\"   title=\"servidores\" data-wpil-keyword-link=\"linked\"  data-wpil-monitor-id=\"1695\">servidores<\/a>O desenvolvimento est\u00e1 sendo realizado pela empresa chinesa Bytedance (que possui o TikTok), que utiliza o CloudFW em seu hardware na sua infraestrutura.      <center>  <div class=\"youtube-placeholder\" data-id=\"gB3wgOuvLJQ\" onclick=\"loadVideo(this)\">\r\n        <img decoding=\"async\" src=\"https:\/\/img.youtube.com\/vi\/gB3wgOuvLJQ\/hqdefault.jpg\" alt=\"Por que no hosting comum a administra\u00e7\u00e3o do PrestaShop \u00e9 lenta, e no seu n\u00e3o \u00e9?\" loading=\"lazy\" width=\"480\" height=\"360\" style=\"width:100%;height:auto;\">\r\n        <div class=\"play-button\"><\/div>\r\n    <\/div>  <\/center><br \/>\n<br \/>Fonte: <a content=\"nofollow\" rel=\"nofollow\" href=\"https:\/\/www.opennet.ru\/opennews\/art.shtml?num=58824\">opennet.ru<\/a> <\/p>","protected":false,"gt_translate_keys":[{"key":"rendered","format":"html"}]},"excerpt":{"rendered":"<p>\u041f\u0440\u0435\u0434\u0441\u0442\u0430\u0432\u043b\u0435\u043d \u0432\u044b\u043f\u0443\u0441\u043a \u0441\u0432\u043e\u0431\u043e\u0434\u043d\u043e\u0439 \u0437\u0430\u0433\u0440\u0443\u0437\u043e\u0447\u043d\u043e\u0439 \u043f\u0440\u043e\u0448\u0438\u0432\u043a\u0438 Libreboot 20230319. \u041f\u0440\u043e\u0435\u043a\u0442 \u0440\u0430\u0437\u0432\u0438\u0432\u0430\u0435\u0442 \u0433\u043e\u0442\u043e\u0432\u0443\u044e \u0441\u0431\u043e\u0440\u043a\u0443 \u043f\u0440\u043e\u0435\u043a\u0442\u0430 coreboot, \u043f\u0440\u0435\u0434\u043e\u0441\u0442\u0430\u0432\u043b\u044f\u044e\u0449\u0443\u044e \u0437\u0430\u043c\u0435\u043d\u0443 \u043f\u0440\u043e\u043f\u0440\u0438\u0435\u0442\u0430\u0440\u043d\u044b\u043c \u043f\u0440\u043e\u0448\u0438\u0432\u043a\u0430\u043c UEFI \u0438 BIOS, \u043e\u0442\u0432\u0435\u0447\u0430\u044e\u0449\u0438\u043c \u0437\u0430 \u0438\u043d\u0438\u0446\u0438\u0430\u043b\u0438\u0437\u0430\u0446\u0438\u0438 CPU, \u043f\u0430\u043c\u044f\u0442\u0438, \u043f\u0435\u0440\u0438\u0444\u0435\u0440\u0438\u0439\u043d\u044b\u0445 \u0443\u0441\u0442\u0440\u043e\u0439\u0441\u0442\u0432 \u0438 \u0434\u0440\u0443\u0433\u0438\u0445 \u043a\u043e\u043c\u043f\u043e\u043d\u0435\u043d\u0442\u043e\u0432 \u043e\u0431\u043e\u0440\u0443\u0434\u043e\u0432\u0430\u043d\u0438\u044f, \u0441 \u043c\u0438\u043d\u0438\u043c\u0438\u0437\u0430\u0446\u0438\u0435\u0439 \u0431\u0438\u043d\u0430\u0440\u043d\u044b\u0445 \u0432\u0441\u0442\u0430\u0432\u043e\u043a.
