Tony Nguyen says: ==================== ice: cleanups and preparation for live migration Jake Keller says: Various cleanups and preparation to the ice driver code for supporting SR-IOV live migration. The logic for unpacking Rx queue context data is added. This is the inverse of the existing packing logic. Thanks to <linux/packing.h> this is trivial to add. Code to enable both reading and writing the Tx queue context for a queue over a shared hardware register interface is added. Thanks to ice_adapter, this is locked across all PFs that need to use it, preventing concurrency issues with multiple PFs. The RSS hash configuration requested by a VF is cached within the VF structure. This will be used to track and restore the same configuration during migration load. ice_sriov_set_msix_vec_count() is updated to use pci_iov_vf_id() instead of open-coding a worse equivalent, and checks to avoid rebuilding MSI-X if the current request is for the existing amount of vectors. A new ice_get_vf_by_dev() helper function is added to simplify accessing a VF from its PCI device structure. This will be used more heavily within the live migration code itself. * '100GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/next-queue: ice: introduce ice_get_vf_by_dev() wrapper ice: avoid rebuilding if MSI-X vector count is unchanged ice: use pci_iov_vf_id() to get VF ID ice: expose VF functions used by live migration ice: move ice_vsi_update_l2tsel to ice_lib.c ice: save RSS hash configuration for migration ice: add functions to get and set Tx queue context ice: add support for reading and unpacking Rx queue context ==================== Link: https://patch.msgid.link/20250710214518.1824208-1-anthony.l.nguyen@intel.com 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 reStructuredText 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.
