- linuxに関する基本的な知識があるソフトウェアエンジニアもしくはヘビーユーザで、Quest 3のlinuxをGUI環境で使いたい人
- apkのインストールとか説明しませんが、Quest 3に入れたやつは、アプリ一覧からカテゴリでUntrusted Sourcesみたいなのを選ぶと出てきます
- termuxの上にlinux distroを載せるのは、遅いのでやりません(下記ベンチマーク参照)。prefixed-rootだろうがシングルユーザだろうがmusl libcだろうが我々なら大丈夫だ!
- linuxアプリのインストールは特記事項ない限り省略します。勝手にpkg installとかして

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:

では、この数字について根拠はなんでしょうか。そもそも何のためにconntrack tableというものがあるのか考えたことはありますか? | |
闇雲に最大値をあげることにたいして抵抗がある方もいると思います。 | |
このテキストは、転職後2日目にGWとして使っているLinux NAT BOXが爆発したことを起因とした、netfilterのチューニングについてまとめようと思います。 |
