Code in the Linux kernel runs in one of three contexts: Process context, kernel thread context, and Interrupt. 5. A World of Bottom Halves Multiple mechanisms are available for bottom halves softirq: (available since 2.3) Random technical bits and thoughts: Linux SoftIRQ based Linux SoftIRQ based applications & throttling & yield Some common packet processing applications are implemented in Linux Kernel in softirq context. Examples include Linux IP tables, IPSec VPN etc.. Based on some questions in checkpoint firewall product forums, it appears that checkpoint firewall and IPSec VPN were also implemented in Linux Linux Device Driver Environment: Deferred Activities Linux (2.4.20) has only 4 softirqs: HI_SOFTIRQ; NET_TX_SOFTIRQ and NET_RX_SOFTIRQ; TASKLET_SOFTIRQ; Relevant for Linux DDE are for now only the first and the latter - NET_* softirqs allow transparent mutli-threading in Linux' network code. HI_SOFTIRQ is for high priority bottom halves as old-style BHs and sound related drivers. 14.04 - Occasional dmesg log "NOHZ: local_softirq_pending
