[PATCH 00/15] Add runtime PM support for libsas
by chenxiang 13 Dec '21

13 Dec '21

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

[PATCH plinth/topic-sas-5.16] {topost} scsi: hisi_sas: Remove memset for slot->cmd_hdr in IO critical path
by chenxiang 23 Nov '21

23 Nov '21

From: Xiang Chen <chenxiang66(a)hisilicon.com> For ssp and stp commands, most fields of slot->cmd_hdr will be overwrote by function prep_ssp_v3_hw() and prep_ata_v3_hw(), so it is not necessary to memset them in front, and just write dw7 and sg_len to 0 for them (dw5 is alway 0). For smp and abort commands, they are not used frequently and most fields of them are not overwrote, so memset slot->cmd_hdr separately for them.
