Alex Elder says: ==================== net: ipa: fix HOLB timer register use The function ipa_reg_init_hol_block_timer_val() generates the value to write into the HOL_BLOCK_TIMER endpoint configuration register, to represent a given timeout value (in microseconds). It only supports a timer value of 0 though, in part because that's sufficient, but mainly because there was some confusion about how the register is formatted in newer hardware. I got clarification about the register format, so this series fixes ipa_reg_init_hol_block_timer_val() to work for any supported delay value. The delay is based on the IPA core clock, so determining the value to write for a given period requires access to the current core clock rate. So the first patch just creates a new function to provide that. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
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.
