then try to update firmware (hence "microcode update" files). If so, it is to my surprise booting Linux can update my CPU, etc. w/out asking me, AFAIK firmware updates if gone wrong can make hardware non-working unless taken to service. Or it does ask if...
A kernel panic is one of several Linux boot issues. In basic terms, it is a situation when the kernel can't load properly and therefore the system fails to boot. During the boot process, the kernel doesn't load directly. Instead,initramfsloads in RAM, then it points to the kernel (vml...
但是在当前的实现中,cpu-clock相当于task-clock.甚至有可能“修复”现有的计数器可能会破坏某些用户空间程序。如果有这样的程序,Linux 可能无法“修复”这个计数器。 Linux 可能需要定义一个新的计数器。 异常(exception):starting with v4.7-rc1,在分析一个或多个 CPU 时 - 而不是特定任务 - 例如perf stat -a...
In a nutshell, when your bootloader (GRUB?) loads your Linux kernel, it is of course the kernel’s job to finish the boot process. But to do so, it might require particular drivers to be able to work with, say, hardware RAID controllers, or a network, and so on. And depending on ...
I'm using busybox for initramfs and I'll be running the kernel on an arm64 virtual machine. The command for getting file is tftp -g -r axpu_ldd_kc.ko my_ip_addr(of course my tftp server is working). But the response is : tftp: sendto: Network is unreachable ...
And here’s where we might part ways regarding terminology. I will always refer to the above file as the “initrd” file since, in my opinion, the “initramfs” early root file system is something quite different. Quite simply, the “initramfs” (initial RAM file system) is what I call...
However, this is obviously not the code used by the kernel, which provides its own routine. How the kernel code reacts in these circumstances is unknown to me. This leaves a few next steps on the table : Check if the tool generating the compressed payload (initramfs?) does pad a few ...
kernel with a specially crafted initramfs in order to make vTPM extract the root volume key. As both the traditional kernel and UKI were using the same signing SecureBoot certificate, it was not possible to check the fact that a genuine RHEL UKI is loaded by just observing the PCR7 value....

In RHEL 7 GA, hostonly_cmdline is newly introduced in /usr/lib/dracut/dracut.conf.d/01-dist.conf file. hostonly_cmdline is set to "no" by default in RHEL 7 GA. What is the impact of hostonly_cmdline on initramfs image? If it is set to "yes" then what is the impact and if ...
