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.

env_dpdk: add DPDK-independent driver information to spdk_pci_driver We want to make struct spdk_pci_driver public, so add env-agnostic fields that define a driver directly to that struct. PCI driver registration (potentially in upper layers) will only use spdk_pci_id-s and spdk pci drv_flags, then those will be translated to DPDK equivalents inside env_dpdk.

pci: register dpdk pci drivers right after init DPDK 18.11+ does its best to ensure all devices are equally attached or detached in all processes within a shared memory group. For SPDK it means that if a device is hotplugged in the primary, then DPDK will automatically send an IPC hotplug request to all other processes. Those other processes may not have the same SPDK PCI driver registered and may fail to attach the device. DPDK will send back the failure status and the primary process will also fail to hotplug its device. To prevent that, we need to pre-register the pci drivers on env init. We register the drivers just after the EAL init because we don't want the matching devices to be picked up by the initial bus probe in DPDK. That's for 2 reasons: 1) we don't want to attach *all* available devices 2) devices attached from non-SPDK context (that is, outside of the spdk attach or enumerate functions) will still fail to attach - the entire attaching process will only take significant amount of time and will bloat the log with useless status messages Change-Id: I7b4c3a2e355f98ea755649f789137f5a727bc935 Signed-off-by: Darek Stojaczyk <dariusz.stojaczyk@intel.com> Reviewed-on: https://review.gerrithub.io/434415 Tested-by: SPDK CI Jenkins <sys_sgci@intel.com> Chandler-Test-Pool: SPDK Automated Test System <sys_sgsw@intel.com> Reviewed-by: Jim Harris <james.r.harris@intel.com> Reviewed-by: Shuhei Matsumoto <shuhei.matsumoto.xt@hitachi.com>
