Struct kernel::introspection::KernelInfo

pub struct KernelInfo { /* private fields */ }

This struct provides the inspection functions.

Implementations

impl KernelInfo

pub fn new(kernel: &'static Kernel) -> KernelInfo

pub fn number_loaded_processes( &self, _capability: &dyn ProcessManagementCapability ) -> usize

Returns how many processes have been loaded on this platform. This is functionally equivalent to how many of the process slots have been used on the board. This does not consider what state the process is in, as long as it has been loaded.

pub fn number_active_processes( &self, _capability: &dyn ProcessManagementCapability ) -> usize

Returns how many processes are considered to be active. This includes processes in the Running and Yield states. This does not include processes which have faulted, or processes which the kernel is no longer scheduling because they have faulted too frequently or for some other reason.

pub fn number_inactive_processes( &self, _capability: &dyn ProcessManagementCapability ) -> usize

Returns how many processes are considered to be inactive. This includes processes in the Fault state and processes which the kernel is not scheduling for any reason.

pub fn process_name( &self, app: ProcessId, _capability: &dyn ProcessManagementCapability ) -> &'static str

Get the name of the process.

pub fn number_app_syscalls( &self, app: ProcessId, _capability: &dyn ProcessManagementCapability ) -> usize

Returns the number of syscalls the app has called.

pub fn number_app_dropped_upcalls( &self, app: ProcessId, _capability: &dyn ProcessManagementCapability ) -> usize

Returns the number of dropped upcalls the app has experience. Upcalls can be dropped if the queue for the app is full when a capsule tries to schedule a upcall.

pub fn number_app_restarts( &self, app: ProcessId, _capability: &dyn ProcessManagementCapability ) -> usize

Returns the number of time this app has been restarted.

pub fn number_app_timeslice_expirations( &self, app: ProcessId, _capability: &dyn ProcessManagementCapability ) -> usize

Returns the number of time this app has exceeded its timeslice.

pub fn number_app_grant_uses( &self, app: ProcessId, _capability: &dyn ProcessManagementCapability ) -> (usize, usize)

Returns a tuple of the (the number of grants in the grant region this app has allocated, total number of grants that exist in the system).

pub fn timeslice_expirations( &self, _capability: &dyn ProcessManagementCapability ) -> usize

Returns the total number of times all processes have exceeded their timeslices.
