irq_softirq_exit
Full Name: IRQ SoftIRQ Exit
Meaning: Counts the occurrences of soft interrupt (softirq) handlers exiting. Softirqs are deferred work that is executed in response to hardware interrupts or kernel events.
irq_softirq_entry
Full Name: IRQ SoftIRQ Entry
Meaning: Tracks the occurrences of soft interrupt handlers starting to execute. It measures the entry point of the softirq handling mechanism.
irq_softirq_raise
Full Name: IRQ SoftIRQ Raise
Meaning: Measures the occurrences of softirqs being raised. Raising a softirq signals the kernel to schedule deferred work for later execution.
kmem_kmem_cache_free
Full Name: Kernel Memory Cache Free
Meaning: Counts the number of times objects are released back to kernel memory caches. Kernel memory caches are used for efficient allocation and deallocation of small objects.
kmem_kmem_cache_alloc
Full Name: Kernel Memory Cache Allocate
Meaning: Counts the occurrences of objects being allocated from kernel memory caches. These operations are optimized for frequent allocations of fixed-sized objects.
net_netif_rx
Full Name: Network Interface Receive
Meaning: Tracks the number of packets received by network interfaces and handed over to the kernel for further processing.
net_netif_rx_ni_exit
Full Name: Network Interface Receive Non-Interruptible Exit
Meaning: Counts the exits from non-interruptible network receive processing paths. Indicates the completion of such processing.
net_netif_rx_ni_entry
Full Name: Network Interface Receive Non-Interruptible Entry
Meaning: Tracks the entry points into non-interruptible processing for packets received by the network interface.
rpm_rpm_usage
Full Name: Runtime Power Management Usage
Meaning: Measures the usage count of runtime power management for devices. Reflects how often devices' power management routines are accessed.
rpm_rpm_resume
Full Name: Runtime Power Management Resume
Meaning: Tracks the number of times devices are resumed from a low-power state by the runtime power management system.
