We use the LF to do the logistics, but it's in no way controlled by them or aligned with their member companies. The first LSF/MM was aided logistically by google, the next by Intel, then USENIX for a while and now the LF. I certainly wouldn't be in favour of turning LSF/MM into a corporate discussion forum ... that's what standards bodies are for.

Hello Nic, Since the LSF/MM summit is organized by the Linux Foundation and since one of the goals of the Linux Foundation is to promote Linux I think every company that is active in both the NVMeOF committee and in the Linux kernel community should be invited.

So what I'd like to discuss wrt this topic is what existing common code relates to vhost-nvme, based on other's fabric driver work already out there. -- To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

[LSF/MM TOPIC] NVMe target support
Hi lsf-pc & Co, I'd like to propose a NVMe target discussion topic for LSF/MM 2016. My interest wrt NVMe target drivers is specifically around using shared infrastructure with existing TCM backend drivers (IBLOCK, FILEIO, RAMDISK), and how se_device->dev_group configfs symlinks can be associated with NVMe target driver ports following HCH's WIP code. Also, there is still a vendor need around some type of NVMe backend driver (eg: target_core_nvme) for exposing + mapping NVMe-HI queues to front-end fabric driver RDMA queues. Beyond the back-end driver discussion, our target_core_fabric_configfs.c logic for exposing a common user-space ABI has served LIO target drivers well over the last 10 upstream fabrics, plus other out-of-tree and WIP drivers. The design has never once had to break userspace ABI compatibility, and the only user-visible addition to original design was allowing network portal attributes to be exposed by fabrics for iser-target + iscsit_transport friends. I think one of the more interesting questions is going to be around how NVMe-over-Fabrics (NVMe_OF) + vhost-nvme will end up using target_core_fabric_configfs.c code. What struct config_groups from target_core_fabric_configfs.c can be common across both SCSI target and NVMe controller export..? The folks for such a discussion would include: Christoph Hellwig, Hannes Reinecke, Dave Minturn, Sagi Grimberg, Ming Lin, Roland Dreier and Mike Christie.
