Replace most BSD 3-clause license text with SPDX identifier. Many open source projects have moved to using SPDX identifiers to specify license information, reducing the amount of boilerplate code in every source file. This patch replaces the bulk of SPDK .c, .cpp and Makefiles with the BSD-3-Clause identifier. Almost all of these files share the exact same license text, and this patch only modifies the files that contain the most common license text. There can be slight variations because the third clause contains company names - most say "Intel Corporation", but there are instances for Nvidia, Samsung, Eideticom and even "the copyright holder". Used a bash script to automate replacement of the license text with SPDX identifier which is checked into scripts/spdx.sh.

update Intel copyright notices per Intel policy to include file commit date using git cmd below. The policy does not apply to non-Intel (C) notices. git log --follow -C90% --format=%ad --date default <file> | tail -1 and then pull just the 4 digit year from the result. Intel copyrights were not added to files where Intel either had no contribution ot the contribution lacked substance (ie license header updates, formatting changes, etc). Contribution date used "--follow -C95%" to get the most accurate date. Note that several files in this patch didn't end the license/(c) block with a blank comment line so these were added as the vast majority of files do have this last blank line. Simply there for consistency.

module/idxd: accel framework plug-in for idxd Docs, RPC, unit tests, etc., will follow. Notes: * The current implementation will only work with VFIO. * The current implementation supports only the existing accel framework API. The API will be expanded for DSA exclusive features in a subsequent patch. * SW is required to manage flow control, to not over-run the work queues. This is provided in the accel plug-in module. The upper layers use public API to manage this. * As we need to support any number of channels (we can't limit ourselves to the number of work queues) we need to dynamically size/resize our per channel descriptor rings based on the number of current channels. This is done from upper layers via public API into the lib. * As channels are created, the total number of work queue slots is divided across the channels evenly. Same thing when they are destroyed, remaining channels will see the ring sizes increase. This is done from upper layers via public API into the lib.

so_ver: increase all major versions To allow SO_MINOR updates on LTS for the whole year it is supported, the major version for all components needs to be increased. This is to prevent scenario where two versions exists with matching versions, but conflicting ABI. Ex. Next SPDK release adds an API call increasing the minor version, then LTS needs just a subset of those additions. Increasing major so version after LTS, allows the future releases to update versions as needed. Yet allowing LTS to increase minor version separately. Disabled test for increasing SO version without ABI change, as that is goal of this patch. This check shall be removed with SPDK 23.05 release. Looks like this was left over from prior LTS, to avoid that make sure it is only skipped when running against v23.01.x as latest release. This patch: - increases SO_VER by 1 for all components - resets SO_MINOR to 0 for all components - removes suppressions for ABI tests Short reference to how the versions were changed: MAX=$(git grep "SO_VER := " | cut -d" " -f 3 | sort -ubnr | head -1) for((i=$MAX;i>0;i-=1)); do find . -name "Makefile" -exec \ sed -i -e "s/SO_VER := $i\$/SO_VER := $(($i+1))/g" {} +; done find . -name "Makefile" -exec \ sed -i -e "s/SO_MINOR := .*/SO_MINOR := 0/g" {} + Change-Id: I3e5681802c0a5ac6d7d652a18896997cd07cc8bf Signed-off-by: Tomasz Zawadzki <tomasz.zawadzki@intel.com> Reviewed-on: https://review.spdk.io/gerrit/c/spdk/spdk/+/16419 Reviewed-by: Ben Walker <benjamin.walker@intel.com> Reviewed-by: Konrad Sztyber <konrad.sztyber@intel.com> Tested-by: SPDK CI Jenkins <sys_sgci@intel.com>

modules/accel_dsa: update IDXD references to DSA where it makes sense IDXD has always been used everywhere but technically it stands for the driver, not the HW (Intel Data Streaming Accelerator Driver) where the X comes from "Streaming Accelerator" somehow. Anyway, the underlying hardware is just DSA. It doesn't matter much now but upcoming patches will add support for a new HW accelerator called the Intel In-Memory Analytics Accelerator which we'll call IAA and it will use the same (mostly) device driver (IDXD) as DSA. So, calling the HW what it is will lessen confusion when adding IAA support. This patch just does renaming for the accel_fw module and associated files (RPC, etc).
