Due to so many misinformation, false claims and confusion that goes around the web I've decided to make this quick comparison of all most known backup enabling tools, hackable vita firmwares and which one you should be using and why.

This is being hosted here, until the reddit post I made gets approved.

I saw, in the recent reddit thread about sighax, a lot of information being posted that's factually incorrect. I'd like to go ahead and clarify how sighax works, and how it's different from arm9loaderhax, while also clearing up some misconceptions I'm seeing (I really dislike misinformation).

What is sighax?

Sighax is an exploit taking advantage of a flaw in the arm9 bootrom, causing the signatures (which those of you less technically oriented may think of as "proofs of authenticity" that normally only Nintendo can generate) for arbitrary firmwares to be read as valid. On a normal boot, if one modifies the header for the firmware partition stored in NAND, the signatur

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:

git add . vs git add -A

Both of these will stage all files, including new files (which git commit -a misses) and deleted files.

The difference is that git add -A also stages files in higher directories that still belong to the same git repository. Here's an example:

/my-repo
  .git/

Intro

perf is very handy, it comes with linux and works without a lot of setup (contrast: oprofile, systemtap)

probes work for kernel and userspace and you can record function arguments and local frame and other variables in the trace

you can use perf script to view the output of such traces, and it will display the variables bundled with the trace, by name, and with the format given when the probe was added

Context

recently someone was asked to record what happened in systemd at source_dispatch, in sd-event; to see what the value of s->description was at the time, they were advised to use gdb
