[−][src]Struct cgroups_rs::cpuset::CpuSetController

pub struct CpuSetController { /* fields omitted */ }

A controller that allows controlling the cpuset subsystem of a Cgroup.

In essence, this controller is responsible for restricting the tasks in the control group to a set of CPUs and/or memory nodes.

Implementations

impl CpuSetController[src]

pub fn new(root: PathBuf, v2: bool) -> Self[src]

Contructs a new CpuSetController with root serving as the root of the control group.

pub fn cpuset(&self) -> CpuSet[src]

Returns the statistics gathered by the kernel for this control group. See the struct for more information on what information this entails.

pub fn set_cpu_exclusive(&self, b: bool) -> Result<()>[src]

Control whether the CPUs selected via set_cpus() should be exclusive to this control group or not.

pub fn set_mem_exclusive(&self, b: bool) -> Result<()>[src]

Control whether the memory nodes selected via set_memss() should be exclusive to this control group or not.

pub fn set_cpus(&self, cpus: &str) -> Result<()>[src]

Set the CPUs that the tasks in this control group can run on.

Syntax is a comma separated list of CPUs, with an additional extension that ranges can be represented via dashes.

pub fn set_mems(&self, mems: &str) -> Result<()>[src]

Set the memory nodes that the tasks in this control group can use.

Syntax is the same as with set_cpus().

pub fn set_hardwall(&self, b: bool) -> Result<()>[src]

Controls whether the control group should be "hardwalled", i.e., whether kernel allocations should exclusively use the memory nodes set via set_mems().

Note that some kernel allocations, most notably those that are made in interrupt handlers may disregard this.

pub fn set_load_balancing(&self, b: bool) -> Result<()>[src]

Controls whether the kernel should attempt to rebalance the load between the CPUs specified in the cpus field of this control group.

pub fn set_rebalance_relax_domain_level(&self, i: i64) -> Result<()>[src]

Contorl how much effort the kernel should invest in rebalacing the control group.

See @CpuSet 's similar field for more information.

pub fn set_memory_migration(&self, b: bool) -> Result<()>[src]

Control whether when using set_mems() the existing memory used by the tasks should be migrated over to the now-selected nodes.

pub fn set_memory_spread_page(&self, b: bool) -> Result<()>[src]

Control whether filesystem buffers should be evenly split across the nodes selected via set_mems().

pub fn set_memory_spread_slab(&self, b: bool) -> Result<()>[src]

Control whether the kernel's slab cache for file I/O should be evenly split across the nodes selected via set_mems().

pub fn set_enable_memory_pressure(&self, b: bool) -> Result<()>[src]

Control whether the kernel should collect information to calculate memory pressure for control groups.

Note: This will fail with InvalidOperation if the current congrol group is not the root control group.
