Ao compilar no modo CONFIG_SSE, o c\u00f3digo de descompacta\u00e7\u00e3o baseado no algoritmo LZMA utiliza instru\u00e7\u00f5es SSE prefetch, permitindo a pr\u00e9-carregamento de dados no cache da CPU sem interromper a opera\u00e7\u00e3o de descompacta\u00e7\u00e3o. Durante os testes da interface SPI com largura de banda de 100Mbit\/s em CPUs m\u00f3veis Intel Sandy Bridge, foi poss\u00edvel reduzir o tempo de carregamento em 46 ms e acelerar a descompacta\u00e7\u00e3o dos componentes payload em 30%.\n<p>Para plataformas Intel Panther Lake, foi implementado suporte para carregamento ass\u00edncrono de arquivos, utilizando SPI DMA para carregar o arquivo fsps.bin paralelamente \u00e0 execu\u00e7\u00e3o de outras tarefas na CPU. Em dispositivos Fatcat, a otimiza\u00e7\u00e3o proposta acelerou o carregamento em 17-18 ms. A efici\u00eancia das opera\u00e7\u00f5es DMA foi aumentada. Uma nova fun\u00e7\u00e3o de sincroniza\u00e7\u00e3o cbfs_preload_wait_for_all() foi adicionada, permitindo concluir opera\u00e7\u00f5es ass\u00edncronas de forma segura antes da desativa\u00e7\u00e3o dos backends de armazenamento. No subsistema Fast SPI DMA, foi implementada uma fila de transfer\u00eancia de dados baseada em tokens, que minimiza as lat\u00eancias entre opera\u00e7\u00f5es DMA sequenciais e proporciona um desempenho de carregamento mais previs\u00edvel.    <\/p>\n<li class=\"l\"> Foi implementada a capacidade de detectar o modo de inicializa\u00e7\u00e3o, permitindo que as plataformas transmitam informa\u00e7\u00f5es cr\u00edticas sobre o estado de inicializa\u00e7\u00e3o para os componentes payload.
