When these failures happen, the warning and call trace is printed which is excessive. Instead, just print the error but rate limited to prevent warns to unnecessarily pollute the kernel log buffer and make the serial console practically unusable. For example, on an AM625 BeaglePlay board where accessing a SDIO WiFi chip fails with an -110 (ETIMEDOUT) error: $ dmesg | grep "sdio write\|read failed (-110)" | wc -l 39 Signed-off-by: Javier Martinez Canillas <javierm@redhat.com> Reviewed-by: Breno Leitao <leitao@debian.org> Signed-off-by: Kalle Valo <kvalo@kernel.org> Link: https://msgid.link/20240228101042.728881-1-javierm@redhat.com
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.
