Struct ShellTestDescriptor 

pub struct ShellTestDescriptor {

    pub numa_nodes: u32,
    pub llcs: u32,
    pub cores: u32,
    pub threads: u32,
    pub memory_mib: u32,
    pub wprof: bool,
    pub extra_include_files: Vec<String>,
    pub scheduler_name: String,
    pub scheduler_kind: SchedulerKind,
    pub wprof_args: Option<String>,
    pub performance_mode: bool,
    pub scheduler_enable_cmds: Vec<String>,
    pub scheduler_disable_cmds: Vec<String>,
}

Wire-format descriptor exchanged between a test binary and cargo ktstr shell --test <NAME> to let the shell VM mirror the named #[ktstr_test]’s topology, scheduler, wprof config, and performance mode.

scheduler_kind is a typed SchedulerKind discriminator so the banner can hint at how to repro the scheduler (Discover/Path = userspace binary at /bin/<n>; KernelBuiltin = no binary, runs scheduler_enable_cmds before drop-to-shell and scheduler_disable_cmds on shell exit; Eevdf = no setup needed).

scheduler_enable_cmds and scheduler_disable_cmds are extracted from the crate::test_support::SchedulerSpec::KernelBuiltin variant’s enable and disable slices respectively; the other three variants emit empty vecs (no kernel-builtin shell ops to invoke).

wprof_args: requires the wprof cargo feature. When the feature is enabled and Some, replaces WprofConfig::args; without the feature, the value is ignored by run_shell. None means “use the default wprof args.”

performance_mode mirrors the test’s #[ktstr_test(performance_mode)] attribute so the shell VM reproduces vCPU pinning, hugepages, NUMA mbind, and SCHED_FIFO promotion when the test requested them.

Fields

numa_nodes: u32

llcs: u32

cores: u32

threads: u32

memory_mib: u32

wprof: bool

extra_include_files: Vec<String>

scheduler_name: String

scheduler_kind: SchedulerKind

wprof_args: Option<String>

Custom wprof CLI args (requires the wprof cargo feature). When Some and the feature is enabled, the shell VM overrides WprofConfig::args with the space-tokenised value before booting.

performance_mode: bool

Mirrors KtstrTestEntry::performance_mode. The shell VM forwards this to crate::vmm::KtstrVmBuilder::performance_mode.

scheduler_enable_cmds: Vec<String>

Shell commands invoked before drop-to-busybox when the test’s scheduler is a crate::test_support::SchedulerSpec::KernelBuiltin variant — empty vec for the other three variants. Populated from the variant’s enable slice.

scheduler_disable_cmds: Vec<String>

Shell commands invoked on shell exit when the test’s scheduler is a crate::test_support::SchedulerSpec::KernelBuiltin variant — empty vec for the other three variants. Populated from the variant’s disable slice.

Trait Implementations

impl Clone for ShellTestDescriptor

fn clone(&self) -> ShellTestDescriptor

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ShellTestDescriptor

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for ShellTestDescriptor

fn default() -> ShellTestDescriptor

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for ShellTestDescriptor

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for ShellTestDescriptor

fn eq(&self, other: &ShellTestDescriptor) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for ShellTestDescriptor

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
