This series implements the iproute2 side of the new DEVLINK_ATTR_FLASH_UPDATE_OVERWRITE_MASK.
This attribute is used to allow userspace to indicate what a device should do with various subsections of a flash component when updating. For example, a flash component might contain vital data such as the PCIe serial number or configuration fields such as settings that control device bootup. The overwrite mask allows the user to specify what behavior they want when performing an update. If nothing is specified, then the update should preserve all vital fields and configuration. By specifying "overwrite identifiers" the user requests that the flash update should overwrite any identifiers in the updated flash component with identifier values 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 Cc: Jiri Pirko <j...@mellanox.com> Cc: Jakub Kicinski <k...@kernel.org> Jacob Keller (2): Update devlink header for overwrite mask attribute devlink: support setting the overwrite mask devlink/devlink.c | 48 ++++++++++++++++++++++++++++++++++-- include/uapi/linux/devlink.h | 27 ++++++++++++++++++++ 2 files changed, 73 insertions(+), 2 deletions(-) base-commit: ad34d5fadb0b4699b0fe136fc408685e26bb1b43 -- 2.28.0.218.ge27853923b9d
