Demora no boot, todas as kexts são lidas

Cassio · September 13, 2011

Atualizado:

Na versão 2.1 r2109 do Chameleon tem um module KernelPatcher.dylib que possibilita o carregamento do kernelcache (que é padrão) juntamente com kexts extras. Coloque em /Extra/modules

http://Olarila.com/forum/viewtopic.php?f=9&t=70

O Clover também carrega kexts da pasta EFI junto com o kernelcache

http://Olarila.com/forum/viewtopic.php?f=9&t=1032

A informação abaixo refere-se a versões anteriores do Chameleon ou se não usar o KernelPatcher.

Se o Chameleon não estiver usando cache de kexts ou kernelcache, todas as kexts serão lidas no boot, e se você usar -v (verbose) o boot vai demorar bastante, mas o que demora é mostrar o nome das kexts na tela, não a leitura em si. Se não usar -v não deve demorar tanto, apenas alguns segundos a mais que o Snow Leopard.

Isso acontece porque o Lion não usa o Extensions.mkext como o Snow Leopard (o cache de kexts não é criado automaticamente), ao invés disso ele usa o kernelcache (pre-linked kernel + kexts), mas o Chameleon não usa esse arquivo por padrão.

Se quiser que o Chameleon use esse arquivo você precisa ativar a opção UseKernelCache (pode usar este app). Com essa opção ativada as kexts de /Extra/Extensions (ou /Extra/Extensions.mkext) não serão carregadas, então você precisa botar todas as kexts em /System/Library/Extensions.

Caso o kernelcache seja mais antigo que a pasta Extensions, ele não será usado e o Chameleon mostrará a seguinte mensagem

Para verificar o que está impedindo o kernelcache de ser atualizado, rode o comando
sudo kextcache -prelinked-kernel
Outra alternativa, se você fizer questão de ter as kexts "hack" na pasta /Extra, é criar o arquivo Extensions.mkext manualmente, mas lembre de atualizá-lo sempre que fizer qualquer mudança na pasta Extensions do sistema
sudo kextcache -v 1 -a i386 -a x86_64 -m /System/Library/Caches/com.apple.kext.caches/Startup/Extensions.mkext /System/Library/Extensions

Ótima dica, realmente dá raiva ele carregando tudo a cada boot, fica perfeito dessa forma.

Marombeiro · January 5, 2012

Realmente a dica é excelente, acabou a demora ao carregar o sistema em -v.

Valeu ˆˆ

Apareceu essa mensagem quando dou o comando sudo kextcache -prelinked-kernel

"Kernel file /mach_kernel does not contain requested arch: i386" Alguma susgestão?

Rode este app e procure por erros no bdmesg http://Olarila.com/forum/viewtopic.php?f=9&t=398

Se você poder analisar o erro, eu agradeço, pois não sei identificar!

Chimera 1.11.0 (svn-r1394) [2012-07-20 08:32:13]

Nunca usei Chimera, uso Chameleon e funciona.

Loading Darwin 10.8
Loading kernel mach_kernel

Não parece ter ativado UseKernelCache.

Deveria aparecer

Loading Darwin 10.8
Loading kernel cache /System/Library/Caches/com.apple.kext.caches/Startup/kernelcache

LoadDrivers: Loading from [/Extra/Extensions.mkext]

A essa altura você não deveria mais ter kexts na Extra

você precisa ativar a opção UseKernelCache. Com essa opção ativada as kexts de /Extra/Extensions (ou /Extra/Extensions.mkext) não serão carregadas, então você precisa botar todas as kexts em /System/Library/Extensions.

deivin503 · August 10, 2012

Deu certo, mas deu kp em AppleIntelCPUPowerManagement, o chameleon.boot.plist estava fora de extra por isso não dava certo! Como resolver esse kp?

Cassio · August 10, 2012

Comece a ler o que tá escrito. Vor repetir de novo

Com essa opção ativada as kexts de /Extra/Extensions (ou /Extra/Extensions.mkext) não serão carregadas, então você precisa botar todas as kexts em /System/Library/Extensions.

O Extensions.mkext que você tem na /Extra deve ter a NullCPUPowerManagement. Ou você instala essa kext em /System/Library/Extensions, ou faz os ajustes necessários pra ter o power management funcionando http://Olarila.com/forum/viewtopic.php?f=2&t=34
