In addition, systemd-modules-load provides several directories for [. SEE ALSO depmod(8) modprobe(8) modprobe. Provided by: msr-tools_1. The kernel uses modprobe to request modules. and it's generally a good idea to use := rather than = in a Makefile, so the variable only gets interpolated once. The x86 kernel supports tracing most MSR (Model Specific Register) accesses. That's the whole point. . 9 and higher, userspace writes to MSR are restricted, for now (in the future this may become impossible) you can allow writing to MSR from userspace using one of the following methods: Hi, I’ve been trying everything that I could find in related threads. In principle you could open a UserVoice to request the functionality be The problem I’m running into is getting the containers to be able to access the MSR module so that they can do the mining at a much more efficient speed. The 2 only communicates that there are two lines containing the string nfnetlink, not necessarily meaning there being a module exactly named nfnetlink For example, ac is the ACPI AC Adapter Driver kernel Those files and the use of msr-tools requires the msr kernel module to be loaded first, sudo modprobe msr.
