linux_session - Linux Remote Session

Linux OS translator.

Translate OS-unaware calls into Linux calls/utilities. Most of Linux distributions are mostly compliant with POSIX standards, so this module only implements the parts that aren’t. This intermediate module implements the common parts of mostly POSIX compliant distributions.

class LshwConfigurationOutput

Bases: TypedDict

The relevant parts of lshw’s configuration section.

link: str

class LshwOutput

Bases: TypedDict

A model of the relevant information from lshw’s json output.

Example

{
...
"businfo" : "pci@0000:08:00.0",
"logicalname" : "enp8s0",
"version" : "00",
"serial" : "52:54:00:59:e1:ac",
...
"configuration" : {
  ...
  "link" : "yes",
  ...
},
...

businfo: str

logicalname: typing_extensions.NotRequired.<class 'str'>

serial: typing_extensions.NotRequired.<class 'str'>

configuration: LshwConfigurationOutput

class LinuxSession

Bases: PosixSession

The implementation of non-Posix compliant parts of Linux.

get_remote_cpus() → list[framework.testbed_model.cpu.LogicalCore]

Overrides get_remote_cpus().

get_dpdk_file_prefix(dpdk_prefix: str) → str

Overrides get_dpdk_file_prefix().

setup_hugepages(number_of: int, hugepage_size: int, force_first_numa: bool) → None

Overrides setup_hugepages().

Raises:

ConfigurationError – If the given hugepage_size is not supported by the OS.

get_port_info(pci_address: str) → tuple[str, str]

Overrides get_port_info().

Raises:

ConfigurationError – If the port could not be found.

bring_up_link(ports: Iterable[Port]) → None

Overrides bring_up_link().

configure_port_mtu(mtu: int, port: Port) → None

Overrides configure_port_mtu().

configure_ipv4_forwarding(enable: bool) → None

Overrides configure_ipv4_forwarding().
