The design of INT indicator register (R_AX_PCIE_HIMR00_V1) is to reduce IO during frequent interrupts, because it can stop chip sending interrupt to host if we just set this indicator to 0, not all IMR(s). This indicator register looks like a root interrupt controller of wifi chip. However, we can't set all other IMR(s) to 0 during we are running on interrupt service routine, or the indicator register can't reflect the status of certain interrupt happened during this period, and then miss some interrupts especially SER interrupt events.

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.
