Merge branch 'implement-kthread-based-napi-poll'

The idea of moving the napi poll process out of softirq context to a kernel
Merge branch 'implement-kthread-based-napi-poll'
Wei Wang says:
==================== implement kthread based napi polle
The idea of moving the napi poll process out of softirq context to a kernel thread based context is not new. Paolo Abeni and Hannes Frederic Sowa have proposed patches to move napi poll to kthread back in 2016. And Felix Fietkau has also proposed patches of similar ideas to use workqueue to process napi poll just a few weeks ago.
The main reason we'd like to push forward with this idea is that the scheduler has poor visibility into cpu cycles spent in softirq context, and is not able to make optimal scheduling decisions of the user threads. For example, we see in one of the application benchmark where network load is high, the CPUs handling network softirqs has ~80% cpu util. And user threads are still scheduled on those CPUs, despite other more idle cpus available in the system. And we see very high tail latencies. In this case, we have to explicitly pin away user threads from the CPUs handling network softirqs to ensure good performance. With napi poll moved to kthread, scheduler is in charge of scheduling both the kthreads handling network load, and the user threads, and is able to make better decisions. In the previous benchmark, if we do this and we pin the kthreads processing napi poll to specific CPUs, scheduler is able to schedule user threads away from these CPUs automatically.
And the reason we prefer 1 kthread per napi, instead of 1 workqueue entity per host, is that kthread is more configurable than workqueue, and we could leverage existing tuning tools for threads, like taskset, chrt, etc to tune scheduling class and cpu set, etc. Another reason is if we eventually want to provide busy poll feature using kernel threads for napi poll, kthread seems to be more suitable than workqueue. Furthermore, for large platforms with 2 NICs attached to 2 sockets, kthread is more flexible to be pinned to different sets of CPUs.
In this patch series, I revived Paolo and Hannes's patch in 2016 and made modifications. Then there are changes proposed by Felix, Jakub, Paolo and myself on top of those, with suggestions from Eric Dumazet.
In terms of performance, I ran tcp_rr tests with 1000 flows with various request/response sizes, with RFS/RPS disabled, and compared performance between softirq vs kthread vs workqueue (patchset proposed by Felix Fietkau). Host has 56 hyper threads and 100Gbps nic, 8 rx queues and only 1 numa node. All threads are unpinned.
req/resp QPS 50%tile 90%tile 99%tile 99.9%tile softirq 1B/1B 2.75M 337us 376us 1.04ms 3.69ms kthread 1B/1B 2.67M 371us 408us 455us 550us workq 1B/1B 2.56M 384us 435us 673us 822us
softirq 5KB/5KB 1.46M 678us 750us 969us 2.78ms kthread 5KB/5KB 1.44M 695us 789us 891us 1.06ms workq 5KB/5KB 1.34M 720us 905us 1.06ms 1.57ms
softirq 1MB/1MB 11.0K 79ms 166ms 306ms 630ms kthread 1MB/1MB 11.0K 75ms 177ms 303ms 596ms workq 1MB/1MB 11.0K 79ms 180ms 303ms 587ms
When running workqueue implementation, I found the number of threads used is usually twice as much as kthread implementation. This probably introduces higher scheduling cost, which results in higher tail latencies in most cases.
I also ran an application benchmark, which performs fixed qps remote SSD read/write operations, with various sizes. Again, both with RFS/RPS disabled. The result is as follows: op_size QPS 50%tile 95%tile 99%tile 99.9%tile softirq 4K 572.6K 385us 1.5ms 3.16ms 6.41ms kthread 4K 572.6K 390us 803us 2.21ms 6.83ms workq 4k 572.6K 384us 763us 3.12ms 6.87ms
softirq 64K 157.9K 736us 1.17ms 3.40ms 13.75ms kthread 64K 157.9K 745us 1.23ms 2.76ms 9.87ms workq 64K 157.9K 746us 1.23ms 2.76ms 9.96ms
softirq 1M 10.98K 2.03ms 3.10ms 3.7ms 11.56ms kthread 1M 10.98K 2.13ms 3.21ms 4.02ms 13.3ms workq 1M 10.98K 2.13ms 3.20ms 3.99ms 14.12ms
In this set of tests, the latency is predominant by the SSD operation. Also, the user threads are much busier compared to tcp_rr tests. We have to pin the kthreads/workqueue threads to limit to a few CPUs, to not disturb user threads, and provide some isolation.
Changes since v9: Small change in napi_poll() in patch 1. Split napi_kthread_stop() functionality to add separately in napi_disable() and netif_napi_del() in patch 2. Add description for napi_set_threaded() and return dev->threaded when dev->napi_list is empty for threaded sysfs in patch 3.
Changes since v8: Added description for threaded param in struct net_device in patch 2.
Changes since v7: Break napi_set_threaded() into 2 parts, one to create kthread called from netif_napi_add(), the other to set threaded bit in napi_enable(), to get rid of inconsistency through all napi in 1 dev. Added documentation for /sys/class/net/<dev>/threaded.
Changes since v6: Added memory barrier in napi_set_threaded(). Changed /sys/class/net/<dev>/thread to a ternary value. Change dev->threaded to a bit instead of bool.
Changes since v5: Removed ASSERT_RTNL() from napi_set_threaded() and removed rtnl_lock() operation from napi_enable().
Changes since v4: Recorded the threaded setting in dev and restore it in napi_enable().
Changes since v3: Merged and rearranged patches in a logical order for easier review. Changed sysfs control to be per device.
Changes since v2: Corrected typo in patch 1, and updated the cover letter with more detailed and updated test results.
Changes since v1: Replaced kthread_create() with kthread_run() in patch 5 as suggested by Felix Fietkau.
Changes since RFC: Renamed the kthreads to be napi/<dev>-<napi_id> in patch 5 as suggested by Hannes Frederic Sowa. ====================

This patch adds a new sysfs attribute to the network device class. Said attribute provides a per-device control to enable/disable the threaded mode for all the napi instances of the given network device, without the need for a device up/down. User sets it to 1 or 0 to enable or disable threaded mode. Note: when switching between threaded and the current softirq based mode for a napi instance, it will not immediately take effect if the napi is currently being polled. The mode switch will happen for the next time napi_schedule() is called.

Merge tags 'spi-nor/for-5.11' and 'nand/for-5.11' into mtd/next
SPI NOR core changes:
- Initial support for stateful Octal DTR mode using volatile settings - Preliminary support for JEDEC 251 (xSPI) and JEDEC 216D standards - Support for Cypress Semper flash - Support to specify ECC block size of SPI NOR flashes - Fixes to avoid clearing of non-volatile Block Protection bits at probe
Generic NAND core: * ECC management: - Add an I/O request tweaking mechanism - Entire rework of the software BCH ECC driver, creation of a real ECC engine, getting rid of raw NAND structures, migration to more generic prototypes, misc fixes and style cleanup. Moved now to the Generic NAND layer. - Entire rework of the software Hamming ECC driver, creation of a real ECC engine, getting rid of raw NAND structures, misc renames, comment updates, cleanup, and style fixes. Moved now to the generic NAND layer. - Necessary plumbing at the NAND level to retrieve generic NAND ECC engines (softwares and on-die). - Update of the bindings.
Raw NAND core: * Geting rid of the chip->ecc.priv entry. * Fix miscellaneous typos in kernel-doc
Raw NAND controller drivers: * AU1550: Ensure the presence of the right includes * Davinci: Do not use extra dereferencing * GPMI: - Fix the driver only sense CS0 R/B issue - Fix the random DMA timeout issue - Use a single line for of_device_id - Use of_device_get_match_data() - Fix reference count leak in gpmi ops - Cleanup makefile - Fix binding matching of clocks on different SoCs * Ingenic: remove redundant get_device() in ingenic_ecc_get() * Intel LGM: New NAND controller driver * Marvell: Drop useless line * Meson: - Fix a resource leak in init - Fix meson_nfc_dma_buffer_release() arguments * mxc: - Use device_get_match_data() - Use a single line for of_device_id - Remove platform data support * Qcom: - Add support for SDX55 - Support for IPQ6018 QPIC NAND controller - Fix DMA sync on FLASH_STATUS register read * Rockchip: New NAND controller driver for RK3308, RK2928 and others * Sunxi: Add MDMA support
SPI-NAND core: * Creation of a SPI-NAND on-die ECC engine * Move ECC related definitions earlier in the driver * Fix typo in comment * Fill a default ECC provider/algorithm * Remove outdated comment * Fix OOB read * Allow the case where there is no ECC engine * Use the external ECC engine logic
SPI-NAND chip drivers: * Micron: - Add support for MT29F2G01AAAED - Use more specific names * Macronix: - Add support for MX35LFxG24AD - Add support for MX35LFxGE4AD
Others: * onenand: Use mtd->oops_panic_write as condition * plat-ram: correctly free memory on error path in platram_probe()
