    magicbook 与debian的故事

    mirrors.tuna.tsinghua.edu.cndebian-security busterupdates main contrib non-freenano 是ctrl+o保存然后回车,按ctrl+xvim是在命令模式下按: 然后输入wq 接着回车改完源之后就需要安装安装firmware-linux-nonfree 我看我的x-server报错为firmware然后输入apt-get install firmware-linux-nonfree接着如果出现YN 输入Y 回车然后等会输入reboot。 但是没有wifi,有蓝牙进入桌面后,使用ctrl+alt+T弹出终端输入apt-get update然后输入apt-get install firmware-iwlwifi一路Y下去然后输入modprobe root.profile 文件最后加上pulseaudio --start --log-target=syslog接着在终端中输入source root.profile使之生效就ok啦总结装好后需要安装firmware-linux-nonfree 不然无法启动桌面环境wifi 需要驱动firmware-iwlwifiroot用户下pluseaudio需要加载。

    IOMMU(三)-初始化

    ineligible for IOMMU domain attach due to platform RMRR requirement),HP的服务器带外管理和正常的流量共用一个网卡,这个网卡只能把流量DMA到一个firmware 规定的物理内存区域(RMRR),如果不在这个区域firmware就拿不到流量,把这个网卡绑定到vfio-pci后,网卡DMA的目的地址是dpdk进程的虚拟地址,虚拟地址对应着大页内存的物理地址,大概率和 firmware上报的RMRR不同,所以vfio-pci就报错不让绑定,解决办法就是升级firmware,在BIOS中disable 网卡shared memory功能。

    AMD芯片架构中TEE实现技术之PSP初探

    PSP firmware is cryptographically signed with a strong key similar to the Intel ME. If the PSP firmware is not present, or if the AMD signing key is not present, the x86 cores will not Furthermore, multiple security vulnerabilities have been demonstrated in AMD firmware in the past, and there is every reason to assume one or more zero day vulnerabilities are lurking in the PSP firmware that you flash, making replacement boot firmware (e.g. libreboot, coreboot) impossible on some boards
