Kernel for Galaxy S24, rebased on CLO sources (WIP)
0200f1b6ba
[ Upstream commit 7ac90b4cf107a3999b30844d7899e0331686b33b ]
On sc7180 when the watchdog timer fires your logs get filled with:
watchdog0: pretimeout event
watchdog0: pretimeout event
watchdog0: pretimeout event
...
watchdog0: pretimeout event
If you're using console-ramoops to debug crashes the above gets quite
annoying since it blows away any other log messages that might have
been there.
The issue is that the "bark" interrupt (AKA the "pretimeout"
interrupt) remains high until the watchdog is pet. Since we've got
things configured as "level" triggered we'll keep getting interrupted
over and over.
Let's switch to edge triggered. Now we'll get one interrupt when the
"bark" interrupt goes off and won't get another one until the "bark"
interrupt is cleared and asserts again.
This matches how many older Qualcomm SoCs have things configured.

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.
