Samuel Mendoza-Jonas says: ==================== net/ncsi: Allow enabling multiple packages & channels This series extends the NCSI driver to configure multiple packages and/or channels simultaneously. Since the RFC series this includes a few extra changes to fix areas in the driver that either made this harder or were roadblocks due to deviations from the NCSI specification. Patches 1 & 2 fix two issues where the driver made assumptions about the capabilities of the NCSI topology. Patches 3 & 4 change some internal semantics slightly to make multi-mode easier. Patch 5 introduces a cleaner way of reconfiguring the NCSI configuration and keeping track of channel states. Patch 6 implements the main multi-package/multi-channel configuration, configured via the Netlink interface. Readers who have an interesting NCSI setup - especially multi-package with HWA - please test! I think I've covered all permutations but I don't have infinite hardware to test on. Changes in v2: - Updated use of the channel lock in ncsi_reset_dev(), making the channel invisible and leaving the monitor check to ncsi_stop_channel_monitor(). - Fixed ncsi_channel_is_tx() to consider the state of channels in other packages. Changes in v3: - Fixed bisectability bug in patch 1 - Consider channels on all packages in a few places when multi-package is enabled. - Avoid doubling up reset operations, and check the current driver state before reset to let any running operations complete. - Reorganise the LSC handler slightly to avoid enabling Tx twice. Changes in v4: - Fix failover in the single-channel case - Better handle ncsi_reset_dev() entry during a current config/suspend operation. ==================== Signed-off-by: David S.

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.
