[Verse 1]
Hardware screams electric warnings through copper veins
CPU drops everything when that signal breaks the chains
Context switching lightning fast, registers preserved in RAM
Kernel mode awakens from its patient, waiting trance
[Chorus]
Interrupt the flow, save the state you know
Top half handles fast, bottom half can grow
Softirq spins in batches, tasklets queue in line
Workqueues thread the heavy loads when we have the time
[Verse 2]
IRQ numbers mapped to vectors in the table's grid
Handler functions registered where urgent work gets bid
Atomic operations guard the critical path tight
Preemption disabled while we race against the clock's bite
[Chorus]
Interrupt the flow, save the state you know
Top half handles fast, bottom half can grow
Softirq spins in batches, tasklets queue in line
Workqueues thread the heavy loads when we have the time
[Bridge]
Network packets flooding in, timer ticks demand attention
Disk controllers crying out for immediate intervention
Split the work strategically between urgent and deferred
Let the scheduler breathe again when priorities are blurred
[Verse 3]
Softirqs process network floods in kernel thread context
Tasklets guarantee serialization, never parallel text
Workqueues sleep when blocked on locks, threads can safely wait
Process context luxury when timing isn't desperate fate
[Chorus]
Interrupt the flow, save the state you know
Top half handles fast, bottom half can grow
Softirq spins in batches, tasklets queue in line
Workqueues thread the heavy loads when we have the time
[Outro]
Hardware screams, kernel dreams of balanced response time
Splitting work across the halves keeps the system's paradigm
