[PATCH net-next v2 0/4] add frag page support in page pool
by Yunsheng Lin 25 Mar '22

25 Mar '22

This patchset adds frag page support in page pool and enable skb's page frag recycling based on page pool in hns3 drvier. V2: 1. resend based on the latest net-next. V1: 1. avoid atomic_long_read() in case of freeing or draining page frag, and drop RFC tag. RFC v6: 1. Disable frag page support in system 32-bit arch and 64-bit DMA. RFC v5: 1. Rename dma_addr[0] to pp_frag_count and adjust codes according to the rename. RFC v4: 1. Use the dma_addr[1] to store bias. 2. Default to a pagecnt_bias of PAGE_SIZE - 1. 3. other minor comment suggested by Alexander. RFC v3: 1. Implement the semantic of "page recycling only wait for the page pool user instead of all user of a page" 2. Support the frag allocation of different sizes 3. Merge patch 4 & 5 to one patch as it does not make sense to use page_pool_dev_alloc_pages() API directly with elevated refcnt. 4. other minor comment suggested by Alexander. RFC v2: 1. Split patch 1 to more reviewable one. 2. Repurpose the lower 12 bits of the dma address to store the pagecnt_bias as suggested by Alexander. 3. support recycling to pool->alloc for elevated refcnt case too. Yunsheng Lin (4): page_pool: keep pp info as long as page pool owns the page page_pool: add interface to manipulate frag count in page pool page_pool: add frag page recycling support in page pool net: hns3: support skb's frag page recycling based on page pool drivers/net/ethernet/hisilicon/Kconfig | 1 + drivers/net/ethernet/hisilicon/hns3/hns3_enet.c | 79 +++++++++++++++-- drivers/net/ethernet/hisilicon/hns3/hns3_enet.h | 3 + drivers/net/ethernet/marvell/mvneta.c | 6 +- drivers/net/ethernet/marvell/mvpp2/mvpp2_main.c | 2 +- drivers/net/ethernet/ti/cpsw.c | 2 +- drivers/net/ethernet/ti/cpsw_new.c | 2 +- include/linux/mm_types.h | 18 ++-- include/linux/skbuff.h | 4 +- include/net/page_pool.h | 68 +++++++++++--- net/core/page_pool.c | 112 +++++++++++++++++++++++- 11 files changed, 258 insertions(+), 39 deletions(-) -- 2.7.4

Dzień dobry! Czy mógłbym przedstawić rozwiązanie, które umożliwia monitoring każdego auta w czasie rzeczywistym w tym jego pozycję, zużycie paliwa i przebieg? Dodatkowo nasze narzędzie minimalizuje koszty utrzymania samochodów, skraca czas przejazdów, a także tworzenie planu tras czy dostaw. Z naszej wiedzy i doświadczenia korzysta już ponad 49 tys. Klientów. Monitorujemy 809 000 pojazdów na całym świecie, co jest naszą najlepszą wizytówką. Bardzo proszę o e-maila zwrotnego, jeśli moglibyśmy wspólnie omówić potencjał wykorzystania takiego rozwiązania w Państwa firmie. Pozdrawiam, Marek Onufrowicz

[RFCv2 net-next 000/167] net: extend the netdev_features_t
by Jian Shen 27 Jan '22

27 Jan '22

For the prototype of netdev_features_t is u64, and the number of netdevice feature bits is 64 now. So there is no space to introduce new feature bit. This patchset try to solve it by change the prototype of netdev_features_t from u64 to bitmap. With this change, it's necessary to introduce a set of bitmap operation helpers for netdev features. Meanwhile, the functions which use netdev_features_t as return value are also need to be changed, return the result as an output parameter. With above changes, it will affect hundreds of files, and all the nic drivers. To make it easy to be reviewed, split the changes to 167 patches to 5 parts. patch 1~22: convert the prototype which use netdev_features_t as return value patch 24: introduce fake helpers for bitmap operation patch 25~165: use netdev_feature_xxx helpers patch 166: use macro __DECLARE_NETDEV_FEATURE_MASK to replace netdev_feature_t declaration. patch 167: change the type of netdev_features_t to bitmap, and rewrite the bitmap helpers. Sorry to send a so huge patchset, I wanna to get more suggestions to finish this work, to make it much more reviewable and feasible. The former discussing for the changes, see [1] [1]. https://www.spinics.net/lists/netdev/msg753528.html ChangeLog: V1->V2: use bitmap by comment from Andrew Lunn Jian Shen (167): net: convert the

Dzień dobry! Czy mógłbym przedstawić rozwiązanie, które umożliwia monitoring każdego auta w czasie rzeczywistym w tym jego pozycję, zużycie paliwa i przebieg? Dodatkowo nasze narzędzie minimalizuje koszty utrzymania samochodów, skraca czas przejazdów, a także tworzenie planu tras czy dostaw. Z naszej wiedzy i doświadczenia korzysta już ponad 49 tys. Klientów. Monitorujemy 809 000 pojazdów na całym świecie, co jest naszą najlepszą wizytówką. Bardzo proszę o e-maila zwrotnego, jeśli moglibyśmy wspólnie omówić potencjał wykorzystania takiego rozwiązania w Państwa firmie. Z poważaniem, Mateusz Talaga

[PATCH] {topost} scsi: hisi_sas: Change the timeout value of phyup
by chenxiang 04 Jan '22

04 Jan '22

From: Xiang Chen <chenxiang66(a)hisilicon.com> Normally phyup will occur very quickly (about 0.1~0.2s) after enabling the PHY, so currently the timeout value of phyup is 2s. But it is possible that it takes more time to wait phyup in some extreme situations. So change the timeout of phyup from 2s to 5s to decrease the possibility that error occurs since the waiting time for phyup is not enough.

From: Xiang Chen <chenxiang66(a)hisilicon.com> Right now hisi_sas driver has already supported runtime PM, and it works well on based function. But for some exception situations, there are some issues related to libsas layer: - Remove a directly attached disk when sas host is suspended, a hang will occur in the resume process, patch 1~2 solve the issue; - Insert a new disk (for expander) during suspended, and the disk is not revalidated when resuming sas host, patch 4~7 solve the issue; - SMP IOs from libsas may be sending when sas host is suspended, so resume sas host when sending SMP IOs in patch 9; - New phyup may occur during the process of resuming controller, then work of DISCE_DISCOVER_DOMAIN of a new phy and work PORTE_BYTES_DMAED of suspended phy are blocked by each other, so defer works of new phys during suspend in patch 10~12; - Work PORTE_BROADCAST_RCVD and PORTE_BYTES_DMAED are in the same workqueue, but it is possible that they are blocked by each other, so keep sas host active until finished some work in patch 14. And patch 3 which is related to scsi/block PM is from Alan Stern (https://lore.kernel.org/linux-scsi/20210714161027.GC380727@rowland.harvard.…) John Garry (3): libsas: Don't always drain event workqueue for HA resume Revert "scsi: hisi_sas: Filter out new PHY up events during suspend" scsi/block PM: Always set request queue runtime active in blk_post_runtime_resume() Xiang Chen (12): scsi: libsas: Add spin_lock/unlock() to protect asd_sas_port->phy_list scsi: hisi_sas: Fix some issues related to asd_sas_port->phy_list scsi: mvsas: Add spin_lock/unlock() to protect asd_sas_port->phy_list scsi: libsas: Send event PORTE_BROADCAST_RCVD for valid ports scsi: hisi_sas: Add more prink for runtime suspend/resume scsi: libsas: Resume sas host before sending SMP IOs scsi: libsas: Add a flag SAS_HA_RESUMING of sas_ha scsi: libsas: Refactor out sas_queue_deferred_work() scsi: libsas: Defer works of new phys during suspend scsi: hisi_sas: Keep controller active between ISR of phyup and the event being processed scsi: libsas: Keep sas host active until finished some work scsi: hisi_sas: Use autosuspend for SAS controller block/blk-pm.c | 22 +++----- drivers/scsi/hisi_sas/hisi_sas.h | 1 + drivers/scsi/hisi_sas/hisi_sas_main.c | 39 +++++++++---- drivers/scsi/hisi_sas/hisi_sas_v3_hw.c | 25 +++++++-- drivers/scsi/libsas/sas_event.c | 77 +++++++++++++++++++++----- drivers/scsi/libsas/sas_expander.c | 3 + drivers/scsi/libsas/sas_init.c | 50 ++++++++++++++++- drivers/scsi/libsas/sas_internal.h | 2 + drivers/scsi/mvsas/mv_sas.c | 5 ++ drivers/scsi/scsi_pm.c | 2 +- include/linux/blk-pm.h | 2 +- include/scsi/libsas.h | 2 + 12 files changed, 182 insertions(+), 48 deletions(-) -- 2.33.0
