This time, I've removed 'detached' scheme introduced in the previous series out of this series to focus on subsystem scheme in ths series. The attach/detach scheme will be introduced in the next series with ns-mgmt functionality. Here's an example of how-to: # Specify a subsystem -device nvme-subsys,id=subsys0 \ -device nvme,serial=foo,id=nvme0,subsys=subsys0 \ -device nvme,serial=bar,id=nvme1,subsys=subsys0 \ -device nvme,serial=baz,id=nvme2,subsys=subsys0 \ -device nvme-ns,id=ns1,drive=drv10,nsid=1,subsys=subsys0 \ -device nvme-ns,id=ns2,drive=drv11,nsid=2,bus=nvme2 \ \ # Not specify a subsystem -device nvme,serial=qux,id=nvme3 \ -device nvme-ns,id=ns3,drive=drv12,nsid=3,bus=nvme3 \ # nvme list -v NVM Express Subsystems Subsystem Subsystem-NQN Controllers ---------------- ------------------------------------------------------------------------------------------------ ---------------- nvme-subsys1 nqn.2019-08.org.qemu:subsys0 nvme0, nvme1, nvme2 nvme-subsys3 nqn.2019-08.org.qemu:qux nvme3 NVM Express Controllers Device SN MN FR TxPort Address Subsystem Namespaces -------- -------------------- ---------------------------------------- -------- ------ -------------- ------------ ---------------- nvme0 foo QEMU NVMe Ctrl 1.0 pcie 0000:00:06.0 nvme-subsys1 nvme1c0n1 nvme1 bar QEMU NVMe Ctrl 1.0 pcie 0000:00:07.0 nvme-subsys1 nvme1c1n1 nvme2 baz QEMU NVMe Ctrl 1.0 pcie 0000:00:08.0 nvme-subsys1 nvme1c2n1, nvme1c2n2 nvme3 qux QEMU NVMe Ctrl 1.0 pcie 0000:00:09.0 nvme-subsys3 nvme3c3n1 NVM Express Namespaces Device NSID Usage Format Controllers ------------ -------- -------------------------- ---------------- ---------------- nvme1n1 1 134.22 MB / 134.22 MB 512 B + 0 B nvme0, nvme1, nvme2 nvme1n2 2 268.44 MB / 268.44 MB 512 B + 0 B nvme2 nvme3n1 3 268.44 MB / 268.44 MB 512 B + 0 B nvme3 Thanks, Since RFC V3: - Exclude 'deatched' scheme from this series. This will be covered in the next series by covering all the ns-related admin commands including ZNS and ns-mgmt. (Niklas) - Rebased on nvme-next. - Remove RFC tag from this V4. Since RFC V2: - Rebased on nvme-next branch with trivial patches from the previous version(V2) applied. (Klaus) - Fix enumeration type name convention with NvmeIdNs prefix. (Klaus) - Put 'cntlid' to NvmeCtrl instance in nvme_init_ctrl() which was missed in V2. - Added 'detached' parameter to nvme-ns device to decide whether to attach or not to controller(s) in the subsystem. (Klaus) - Implemented Identify Active Namespace ID List aprt from Identify Allocated Namespace ID List by removing fall-thru statement. Since RFC V1: - Updated namespace sharing scheme to be based on nvme-subsys hierarchy.
