HPA PCIe Passthrough Policy Example

pciCount

pciVendorId

pciDeviceId

pciePassthrough

pci_passthrough:alias=ALIAS:COUNT

Openstack administrator is expected to create ALIAS as

<name>-<PCIe vendor ID in Hex>-<PCIe device ID>

QuickAssist example: "mycrypto-8086-0443"

In case of SRIOV-NIC:

aggregate_instance_extra_specs:sriov-device-<name>="<Vendor ID>-<Device ID>"

It is expected that Openstack administrator creates host aggregate and metadata 'sriov-device-<name>' .

Example: Assume that there are two SRIOV-NIC cards supported by a region, Intel and Mellanox.

Examples:

sriov-device-intel=8086-1563

sriov-device-mellanox=15B3-1003

HPA Huge Pages Policy Example

memoryPageSize

hugePages

hw:mem_page_size

values can be ANY, 4KB, 2MB, 1GB

How to handle large, small, any from openstack?

if the hw:mem_page_size is an integer it is assumed the unit is in KB
