piCorePlayer6.1.0-Xenomai-44.1-48KHz雙機入門簡易安裝教學

原來 Xenomai 的 20 週年紀念是 2021 年 8 月 20 日：

另外有一些關於 KVM 和 out-of-band 的東西：

I probably should not assume that everyone here knows what KVM is, so let me explain.

That's why most servers provide out of band management interface. Think of it as an option to use keyboard, video, and mouse remotely from a web-browser. It's a low-level hardware device that does not need an operating system to operate.

And what if I use HQplayer with no oversampling and connect via KVM to control the software. Well, this my friends was one of the biggest improvements on my DIY server.

大約一年前 Philippe Gerum 兄亦有提及這些關於 EVL network stack 和 out-of-band 的課題：

https://evlproject.org/pipermail/evl...ly/000189.html

Depending on how low is low latency, I may have to implement in the driver a fast channel for talking to the EVL network stack directly from the out-of-band context, guaranteeing the bare minimum EVL can support in terms of jitter.

然後 linux-evl 最新的一些 commits 已經加入這個 net core 以及 dovetail 的 out-of-band networking：

小弟的猜想是這樣的，理論上好像有可能篩選／分隔 network traffic 的說，那麼有沒有方法參考 CPU core isolation 的方法，把最重要的 traffic 和其他跟音樂無關的 traffic 分配給 in-band 和 out-of-band 呢？

- a selected portion of the traffic flowing in and out NIC drivers can be diverted though the out-of-band stack.

Nenon 兄還指出無網路（zero traffic？）就是最好的網路：

2. No matter what you do, network activity has impact on the server performance. No network is the best network.

不知道有沒有可能參考這個 stop_idlenet() 的方法，當沒有任何 network traffic 的時候就把 in-band 或者 out-of-band 的部分暫時關上：
