Alex Elder says: ==================== net: ipa: GSI interrupt handling fixes This series implements fixes for some issues related to handling interrupts when GSI channel and event ring commands complete. The first issue is that the completion condition for an event ring or channel command could occur while the associated interrupt is disabled. This would cause the interrupt to fire when it is subsequently enabled, even if the condition it signals had already been handled. The fix is to clear any pending interrupt conditions before re-enabling the interrupt. The second and third patches change how the success of an event ring or channel command is determined. These commands change the state of an event ring or channel. Previously the receipt of a completion interrupt was required to consider a command successful. Instead, a command is successful if it changes the state of the target event ring or channel in the way expected. This way the command can succeed even if the completion interrupt did not arrive while it was enabled. ==================== Link: https://lore.kernel.org/r/20201222180012.22489-1-elder@linaro.org Signed-off-by: Jakub Kicinski <kuba@kernel.org>
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.
