[PATCH kernel-4.19] net_sched: remove need_resched() from qdisc_run()
by Yang Yingliang 15 Oct '21

15 Oct '21

From: Eric Dumazet <edumazet(a)google.com> mainline inclusion from mainline-v5.5-rc1 commit b60fa1c5d01a10e358c509b904d4bead6114d593 category: bugfix bugzilla: 182865 CVE: NA ------------------------------------------------- The introduction of this schedule point was done in commit 2ba2506ca7ca ("[NET]: Add preemption point in qdisc_run") at a time the loop was not bounded. Then later in commit d5b8aa1d246f ("net_sched: fix dequeuer fairness") we added a limit on the number of packets. Now is the time to remove the schedule point, since the default limit of 64 packets matches the number of packets a typical NAPI poll can process in a row. This solves a latency problem for most TCP receivers under moderate load : 1) host receives a packet. NET_RX_SOFTIRQ is raised by NIC hard IRQ handler 2) __do_softirq() does its first loop, handling NET_RX_SOFTIRQ and calling the driver napi->loop() function 3) TCP stores the skb in socket receive queue: 4) TCP calls sk->sk_data_ready() and wakeups a user thread waiting for EPOLLIN (as a result, need_resched() might now be true) 5) TCP cooks an ACK and sends it. 6) qdisc_run() processes one packet from qdisc, and sees need_resched(), this raises NET_TX_SOFTIRQ (even if there are no more packets in the qdisc) Then we go back to the __do_softirq() in 2), and we see that new softirqs were raised. Since need_resched() is true, we end up waking ksoftirqd in this path : if (pending) { if (time_before(jiffies, end) && !need_resched() && --max_restart) goto restart; wakeup_softirqd(); } So we have many wakeups of ksoftirqd kernel threads, and more calls to qdisc_run() with associated lock overhead. Note that another way to solve the issue would be to change TCP to first send the ACK packet, then signal the EPOLLIN, but this changes P99 latencies, as sending the ACK packet can add a long delay.

[PATCH openEuler-1.0-LTS 1/2] cache: Workaround HiSilicon Taishan DC CVAU

From: Weilong Chen <chenweilong(a)huawei.com> ascend inclusion category: feature bugzilla: 46922 CVE: NA ------------------------------------- Taishan's L1/L2 cache is inclusive, and the data is consistent. Any change of L1 does not require DC operation to brush CL in L1 to L2. It's safe that don't clean data cache by address to point of unification. Without IDC featrue, kernel needs to flush icache as well as dcache, causes performance degradation. The flaw refers to V110/V200 variant 1.
