Read the project’s introduction
Linux kernel
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use make htmldocs or
make pdfdocs. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.

5 sourcesArch Linux has a decent guide explaining the behind-the-scenes stuff: https://wiki.archlinux.org/index.php/Power_management/Suspen...
On desktops and laptops, it Usually Should Just Work (tm). The general culprits for issues are proprietary graphics and wifi drivers as well as shoddy BIOSes with broken ACPI tables, but I never had to dig this deep.
For embedded systems, the situation is more complex, as the chipset needs to support it - suspend itself is not the problem in most cases, but wakeup is - for example, the Raspberry Pi does not have a dedicated interrupt (https://github.com/raspberrypi/linux/issues/1281). If you're working with an embedded chipset, your best bet is the manufacturer, they have to deal with that in the BSP.
In Automotive Grade LinuxI was curious about this as well. The issue appears to be lack of scatter-gather support. See: https://github.com/raspberrypi/linux/issues/875#issuecomment...
In UASP makes Raspberry Pi 4 disk IO 50% fasterSorry if it was short on software details.
It's realtime raspbian. Headless ardour (lua implementation). A mix of guitarix and other amp sims. Proprietary cab sim IRs. Various other effects packages like rkr, ardour-native plugins.
Person speaks to alexa, alexa calls a series of lambdas (basically the not-yet-public API), and sends MQTT messages to the device which is tied to the user's Thingamagig account which is linked to their Alexa account.

Let me know if you have any other questions.
