Functions ¶

func AddDevice ¶

func AddDevice(ctx context.Context, vm *uvm.UtilityVM, idType, deviceID string, index uint16, deviceUtilPath string) (vpci *uvm.VPCIDevice, locationPaths []string, err error)

AddDevice is the api exposed to hcsoci to handle assigning a device on a UVM

`idType` refers to the specified device's type, supported types here are `VPCIDeviceIDType` and `VPCIDeviceIDTypeLegacy`.

`deviceID` refers to the specified device's identifier. This must refer to a device instance id for hyper-v isolated device assignment.

`deviceUtilPath` refers to the path in the UVM of the device-util tool used for finding the given device's location path(s).

Returns the allocated vpci device in `vpci` to be tracked for release by the caller. On failure in this function, `vpci` is released and nil is returned for that value.

Returns a slice of strings representing the resulting location path(s) for the specified device.

func InstallWindowsDriver ¶

func InstallWindowsDriver(ctx context.Context, vm *uvm.UtilityVM, driver string) (closer resources.ResourceCloser, err error)

InstallWindowsDriver mounts a specified kernel driver using vsmb, then installs it in the UVM.

`driver` is a directory path on the host that contains driver files for standard installation.

Returns a ResourceCloser for the added vsmb share. On failure, the vsmb share will be released, the returned ResourceCloser will be nil, and an error will be returned.
