The recently added DEVLINK_ATTR_FLASH_UPDATE_OVERWRITE_MASK allows userspace to indicate how a device should handle subsections of a flash component when updating. For example, a flash component might contain vital data such as PCIe serial number or configuration fields such as settings that control device bootup. The overwrite mask allows specifying whether the device should overwrite these subsections when updating from the provided image. If nothing is specified, then the update is expected to preserve all vital fields and configuration. Add support for specifying the overwrite mask using the new "overwrite" option to the flash command line. By specifying "overwrite identifiers", the user request that the flash update should overwrite any settings in the updated flash component with settings from the provided flash image $devlink dev flash pci/0000:af:00.0 file flash_image.bin overwrite identifiers By specifying "overwrite settings" the user requests that the flash update should overwrite any settings in the updated flash component with setting values from the provided flash image. $devlink dev flash pci/0000:af:00.0 file flash_image.bin overwrite settings These options may be combined, in which case both subsections will be sent in the overwrite mask, resulting in a request to overwrite all settings and identifiers stored in the updated flash components. $devlink dev flash pci/0000:af:00.0 file flash_image.bin overwrite settings overwrite identifiers Signed-off-by: Jacob Keller <jacob.e.keller@intel.com> Signed-off-by: David Ahern <dsahern@gmail.com> |

How to compile this.
--------------------
1. libdbm
arpd needs to have the berkeleydb development libraries. For Debian
users this is the package with a name like libdbX.X-dev.
DBM_INCLUDE points to the directory with db_185.h which
is the include file used by arpd to get to the old format Berkeley
database routines. Often this is in the db-devel package.
2. make
The makefile will automatically build a config.mk file which
contains definitions of libraries that may or may not be available
on the system such as: ATM, ELF, MNL, and SELINUX.
3. To make documentation, cd to doc/ directory , then
look at start of Makefile and set correct values for
PAGESIZE=a4 , ie: a4 , letter ... (string)
PAGESPERPAGE=2 , ie: 1 , 2 ... (numeric)
and make there. It assumes, that latex, dvips and psnup
are in your path.
4. This package includes matching sanitized kernel headers because
the build environment may not have up to date versions. See Makefile
if you have special requirements and need to point at different
kernel include files.
