Author: Paolo Abeni Date: Mon May 8 08:17:44 2023 +0200 Revert "softirq: Let ksoftirqd do its job" This reverts the following commits: 4cd13c21b207 ("softirq: Let ksoftirqd do its job") 3c53776e29f8 ("Mark HI and TASKLET softirq synchronous") 1342d8080f61 ("softirq: Don't skip softirq execution when softirq thread is parking") in a single change to avoid known bad intermediate states introduced by a patch series reverting them individually. Due to the mentioned commit, when the ksoftirqd threads take charge of softirq processing, the system can experience high latencies. In the past a few workarounds have been implemented for specific side-effects of the initial ksoftirqd enforcement commit: commit 1ff688209e2e ("watchdog: core: make sure the watchdog_worker is not deferred") commit 8d5755b3f77b ("watchdog: softdog: fire watchdog even if softirqs do not get to run") commit 217f69743681 ("net: busy-poll: allow preemption in sk_busy_loop()") commit 3c53776e29f8 ("Mark HI and TASKLET softirq synchronous") But the latency problem still exists in real-life workloads, see the link below. The reverted commit intended to solve a live-lock scenario that can now be addressed with the NAPI threaded mode, introduced with commit 29863d41bb6e ("net: implement threaded-able napi poll loop support"), which is nowadays in a pretty stable status. While a complete solution to put softirq processing under nice resource control would be preferable, that has proven to be a very hard task. In the short term, remove the main pain point, and also simplify a bit the current softirq implementation.
