Of course, they are available for tech enthusiasts like you. But look at your Asus 10Gbe card with a passive cooler [1], and I bet your 10Gbe switch gets pretty hot or you are using a big switch. They have thermal/space limitations - t

Then what are the use cases of IB at home? I mean, the comments talk about IB at home, so I am really curious.

10GBASE-T has a different story to USB3. 10GBASE-T consumes too much power (2-5 Watts!) and generates too much heat for a single port (a transceiver can go up to 90 celsius!) , so it is not suitable for most of areas, including for home NIC

Does USB4/Thunderbolt will change the story? I heard their signaling is quite different than USB3.

That is so weird. If they don't share the same codebase then why Canonical would want to use "Anbox" trademark?
222.
by kbumsik 6y ago
That's pretty good sign! These kinds of open source emulators or similar stuff usually driven by individuals and often have risk of being unmaintained. But this project is used by larger companies like Canonical so we can expect better

The delay is just 10ms and this is a bootloader code that runs only once at bootup. As a bootloader for an MCU, a less error-prone way with less code size is more preferrable.
224.
by kbumsik 6y ago
The OP delay loop is for MCU/Arduino where embedded devs typically have all control of the PLLs and know exact CPU timings. You can see that the other part of the bootloader example fixes all related clocks manually. [1] These MCUs are

But the example here is to simply delay, not to sleep for power consumption.
226.
by kbumsik 6y ago
I agree. Using timer is not as deterministic as precisely-calculated NOP loop. And why even bother setting timer peripherals if it is to delay for 10ms once in the entire program?
227.
by kbumsik 6y ago
To be fair, this is not a "sleep" routine, but a delay routine. The purpose of the function is to give a slight delay until other part of the hardware is ready. This is actually the most deterministic (so it means great) way to do

A good real-world example is the Arduino bootloader. [1] Once you read the OP and learn basic idea, it is pretty simple. [1] https://github.com/arduino/ArduinoCore-samd/blob/master/boot...

So then the OP is a LGPL header-only library, which is always statically compiled in every source. Do we need to do the same thing, and if yes, how we provide an application to allow recompiling?
230.
by kbumsik 6y ago
I am confused with that paragraph. So if I statically compiled a project with Qt without any modification, does it fall outside the scope of LGPL as well?
231.
by kbumsik 6y ago
In this case I interpret LGPL as "Please don't maintain your own fork (with bugfixs) in your company internally, contribute to my repo directly", which make sense.

I took a OS class with Xv6. As a Linux kernel dev I can tell you Xv6 is great for teaching OS than Linux. 1. I remember the first assignment if the class was adding a new syscall. It was quite trivial task for Xv6 because Xv6 syscall layers
