Title:
[Feature] Volume Management Device (VMD) Driver
Status in intel:
Fix Released
Status in linux package in Ubuntu:
Fix Released
Bug description:
The Volume Management Device (VMD) is a secondary PCI Express host bridge
provided by the Intel CPU. Individual CPU-attached root ports, and all devices
behind them, may be configured by BIOS to appear underneath VMD instead of
underneath the primary root bus.
VMD is represented by a root bus integrated endpoint, which serves as a proxy
to the devices beneath it for access to configuration space, MMIO, DMA, and MSI.
The VMD driver implements Linux's PCI host bridge interface. When probed, the
driver dynamically creates a new PCI domain(segment). The PCI subsystem
enumerates the VMD PCI domain and loads drivers for devices and ports it finds.
A software validation team is testing the driver with VMD-enabled servers,
PCIe switches, and NVMe PCIe SSDs. They will also be testing error handling and
hotplug for SSDs behind VMD-owned root ports.
