This series implements the new i40e driver for Intel's upcoming
Intel(R) Ethernet Controller XL710 Family of devices.
V7: many changes from a few comments:
use linux errno types
change I40E_SUCCESS to 0, standardize returns
change s32 return values to int
use void return values where possible
prefer use of int over i40e_status
V6: rename Kbuild to Makefile
rename i40e_mem[set|cpy] to regular memset/memcpy
V5: remove sysfs support from this set, will rearchitect
changes from community comments
V4: addresses remaining community comments, mostly trivial edits.
major sparse based cleanup of possible endian issues
removal of most of __func__ references
sizeof(*var) instead of sizeof(struct ...)
change 'NULL ==' tests to !NULL
implement xps
use kernel bitshift macros (upper_32_bits, etc)
V3: many more individual comments addressed, thanks reviewers! Many
other changes due to internal review and development.
V2: each patch has individual comments, in general, feedback from the
list was applied and addressed. Many changes due to internal review
and coding as well.
V1: initial send
Let me start by saying thanks and we appreciate any time spent by
those of you who review and comment on this new driver, and we will
attempt to address and respond to all issues brought to our attention.
I tried to break the patches up to ease review, but the series should
apply and still be bisectable, as the last patch adds the driver to
the kernel compile with CONFIG_I40E.
This driver is for a brand new bit of silicon that has a different
design than other Intel Ethernet silicon, and therefore needed a new
driver.
The hardware has quite a bit of capability and this driver is only
meant to provide basic functionality at first. Future patches will
continue to add functionality and bug fixes.
This initial release is very early in the product cycle with the intent
of getting initial support into the kernel before users have the
hardware available to purchase. A software development manual is not
ready yet but will be available when the hardware ships.
The driver development model and interaction with community submitted
patches *will not be any different* than what we are currently doing
today. We plan to continue established processes.
An associated i40evf driver has been posted for review.
List of tools we ran in preparation:
way more sparse clean
make W=1, W=2 clean
checkpatch (almost) clean
total: 1 errors, 4 warnings, 30461 lines checked
NOTE: Ignored message types: LONG_LINE
- issues have been addressed and the remainders
are noise.
codespell clean
smatch (almost) clean with a couple minor warnings
coccicheck clean
namespacecheck clean
allmodconfig clean
ppc64 build clean (untested)
This driver is a team effort, thank you to Joseph Gasparakis,
Shannon Nelson, Anjali Singhai-Jain, Mitch Williams, Neerav
Parikh, Vasu Dev, Kavindya Deegala, Yi Zou, and PJ Waskiewicz.
TODO (known issues)
BQL implementation
finish rtnl_stat64 locking (we have a patch but debugging it)
