[PATCH net-next 0/6] net/ncsi: Allow enabling multiple packages & channels
From: Samuel Mendoza-Jonas
Date: Wed Oct 17 2018 - 23:59:55 EST
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
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.
Samuel Mendoza-Jonas (6):
net/ncsi: Don't enable all channels when HWA available
net/ncsi: Probe single packages to avoid conflict
net/ncsi: Don't deselect package in suspend if active
net/ncsi: Don't mark configured channels inactive
net/ncsi: Reset channel state in ncsi_start_dev()
net/ncsi: Configure multi-package, multi-channel modes with failover
