Meetings are public and DPDK community members ar= e welcome to attend. =20 NOTE: Next meeting will be on Wednesday 2019-11-06 @3pm UTC, and will be ch= aired by Jerin 1. SPDX Discussions Hemant and Stephen provided an update on the gaps to be closed for achiev= ing use of SPDX tags alone (i.e. no license text in files) in 19.11.=20 Key gaps: =20 * Issue identified with pmdinfogen using GPL derived code, meaning it needs a license exception. Stephen to follow with GB to get exceptio= n approval.=20 =20 * Few drivers, test files are still having old licensing style. Patches have been created, but we are still waiting for original authors to ack them.=20 * In the worst, we will apply top SPDK tag while leaving the original License text in the file intact for the remaining files. 2. MIT license for Windows. - The code has been re-submitted as BSD-3 (or MIT+BSD-3), we will check th= e legal team for any concerns.=20 - TB will check for global exception for dual licensing.=20 3. Removal of examples (standing agenda item): All the removed examples should be mentioned in Release notes. Bruce's patchset (5 examples) was agreed. =20 Jin Yu also submitted a patch to remove vhost_scsi example. 4. KNI IOVA as VA support KNI supposes that mbufs are contiguous in kernel virtual memory. This may n= ot be true when using the IOVA=3DVA mode. - check original context at http://mails.dpdk.org/archives/dev/2019-Octob= er/148339.html - It is not wise to break KNI - as customers are using it in production. - choice to enable it optionally with EAL FLAG is not acceptable to Jerin= .=20 - Olivier's new mempool patch series for " mempool: avoid objects allocat= ions across pages" will help here.=20 The decision is to accelerate the review of this mempool patch series and m= ake it part of 19.11 itself to resolve this issue.=20 5. VFIO - PF Kernel module - enabling SRIOV of VFIO PF device.=20 - some members raised concerns for supporting out of tree kernel modules (e= specially related to VM) as it creates lots of long term support nightmare. - for this particular module, kernel.org is not in favour on integrating th= ese changes as this may cause security issue with netdev - mcoquelin and shemminger to review it further and discuss this topic agai= n in next meeting.7
