Do you know any website similar to "elixir.bootlin.com"

[VisualLab]

From time to time, I work on some simple projects on Raspberry Pi (version 3), of course under the control of Linux (Raspberry Pi OS). For this purpose I use Lazarus. The projects concern GPIO support (and to a limited extent: PWM, I2C, SPI). In my projects, I try to refer directly to the interfaces provided by Linux. For this purpose, I have been using the website "elixir.bootlin.com" for several years. Its advantage was that it allowed for quick and easy viewing and searching of Linux kernel source files. I am mainly interested in UAPI (headers) regarding support for: GPIO, I2C, SPI, PWM, etc. peripherals.

Today, unexpectedly, it turned out that this website was not working. In the suggestions returned by the Google search engine, information appears that it has been disabled. So, does any Free Pascal or Lazarus user know any other website that would allow you to browse Linux kernel source files in a similar way?

Of course, I'm going to look for such a website. However, I thought that if someone already uses a similar website, it wouldn't hurt to ask on the forum.

For me the mentioned website loads. I am unsure how to test that site since I am not aware about anything LINUX specific

So I guess I was in a hurry unnecessarily. Indeed, the mentioned website is already operational. In any case, for some time (today, about an hour) there was no access to it (or something went wrong in part of the network in my region).

Either way, it's good that it's available.

By a quick research about alternates:
https://lxr.linux.no/linux
https://makelinux.github.io/kernel/map/

While the first offer a search similar to your mentioned site the second is different

Thank you for the information. I will add it to my bookmarks in my browser. In the case of the LXN website, I remembered that I had looked at it before (I recognised it by the logo visible in the upper right corner).

https://web.archive.org/web/20240000000000*/elixir.bootlin.com which shows it was last archived a couple of weeks ago.

If this is something on which you rely heavily, I suggest that using something like https://superuser.com/questions/828907/how-to-download-a-website-from-the-archive-org-wayback-machine to make your own local copy would be in order.

As a general point for the future, I suggest that a title specifically referring to e.g. "any documentation website" would be more helpful.
