主要作用是检查CPU ID, Architecture Type,初始化BSS等操作,并跳到start_kernel函数。在执行前,处理器应满足以下状态: r0 - should be 0 r1 - unique architecture number MMU - off I-cache - on or off D-cache – off /* 部分源代码分析 */ ...
此外,6.13 支持在 Arm CCA (Confidential Compute Architecture) 下的受保护虚拟机(又称为领域)中运行 Linux;并通过受控控制堆栈 (GCS) 为 AArch64 (ARM64) 提供用户态影子栈支持。 6.13 引入了 AMD 3D V-Cache 优化器驱动程序,多 CCD 的锐龙 R9 X3D 处理器从而受益,而且新的 AMD EPYC 9005“Turin”服务...
一款全新的虚拟CPUfreq驱动被引入,旨在协调主机和虚拟机(VM)系统中的CPU频率。通过将虚拟CPU的频率作为「提示」发送给主机,该驱动能够有效优化虚拟机内部任务的性能和能效,为虚拟机的高效稳定运行提供了关键支持。 ARM CCA支持:强化安全与开发体验 对于需要在ARM Confidential Compute Architecture (CCA)的受保护VM中运行...
