The ice driver supports a region for both the flat NVM contents as well as the Shadow RAM which is a layer built on top of the flash during device initialization. These regions use an almost identical read function, except that the NVM needs to set the direct flag when reading, while Shadow RAM needs to read without the direct flag set. They each call ice_read_flat_nvm with the only difference being whether to set the direct flash flag. The NVM region read function also was fixed to read the NVM in blocks to avoid a situation where the firmware reclaims the lock due to taking too long. Note that the region snapshot function takes the ops pointer so the function can easily determine which region to read. Make use of this and re-use the NVM snapshot function for both the NVM and Shadow RAM regions. This makes Shadow RAM benefit from the same block approach as the NVM region. It also reduces code in the ice driver. Signed-off-by: Jacob Keller <jacob.e.keller@intel.com> Acked-by: Jakub Kicinski <kuba@kernel.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.
