Pre-requisites

Install IPMItools using your package manager on laptop and target machine. Load the drivers on the target.

modprobe ipmi_devintf
modprobe ipmi_si

If you see the following, drivers are not loaded.

# Build with:
#     NIX_PATH=nixpkgs=$HOME/src/nixpkgs nix-build --no-link '<nixpkgs/nixos>' -A config.system.build.tarball -I nixos-config=thisfile.nix
# You can also use
#     -A config.system.build.toplevel
# to build something you can browse locally (that uses symlinks into your nix store).

  # We need no bootloader, because the Chromebook can't use that anyway.

Here's a list of mildly interesting things about the C language that I learned mostly by consuming Clang's ASTs. Although surprises are getting sparser, I might continue to update this document over time.

There are many more mildly interesting features of C++, but the language is literally known for being weird, whereas C is usually considered smaller and simpler, so this is (almost) only about C.

1. Combined type and variable/field declaration, inside a struct scope [https://godbolt.org/g/Rh94Go]

struct foo {
   struct bar {
 int x;

TDP and turbo parameter modification with MSR on non-overclockable CPU

Disclaimer

• MSR modification may void your CPU's (or system board's) warranty. Proceed with care. I'm not responsible for any destruction caused by this article.
• MSR address (greatly) differs from CPU to CPU. Check your own CPU's MSR address using Intel's documentation.
• Only tested on Intel i7-8550U (Kaby Lake R).
• This article is translation of this article. If you can understand Korean, I recommend reading that article, not this.

# Why?
# To paste text into windows that normally don't allow it or have access to the clipboard.
# Examples: Virtual machines that do not yet have tools installed, websites that hijack paste
#
# Extended vs Simple?
# * Includes an initial delay to allow you to change active windows
# * Adds small delay between keypresses for slower responding windows like SSH sessions
# * Better handling of numbers
# * VMWare bug fix

Tuning Intel Skylake and beyond for optimal performance and feature level support on Linux:

Note that on Skylake, Kabylake (and the now cancelled "Broxton") SKUs, functionality such as power saving, GPU scheduling and HDMI audio have been moved onto binary-only firmware, and as such, the GuC and the HuC blobs must be loaded at run-time to access this functionality.

Enabling GuC and HuC on Skylake and above requires a few extra parameters be passed to the kernel before boot.

Instructions provided for both Fedora and Ubuntu (including Debian):

Note that the firmware for these GPUs is often packaged by your distributor, and as such, you can confirm the firmware blob's availability by running:
