This series adds runtime PM support for v3 hw. Consists of: - Switch to new PM suspend and resume framework - Add links to devices to ensure host cannot be suspended while devices are not - Filter out phy events during suspend to avoid deadlock - Add controller RPM support - And some more minor misc related changes
I also included a random small fix, only visible when #CPUs < #queues and MSI affinity module param set. Note that this series does not conflict with patch "scsi: hisi_sas: Switch v3 hw to MQ", which is supposed to go through the block tree: https://lore.kernel.org/linux-scsi/32574da3d8de863ff38347ef6ead9...@mail.gmail.com/T/#m39c82fc8a3e3a6b20247d0bd0122d2916e620a28 Luo Jiaxing (1): scsi: hisi_sas: Use hisi_hba->cq_nvecs for calling calling synchronize_irq() Xiang Chen (6): scsi: hisi_sas: Switch to new framework to support suspend and resume scsi: hisi_sas: Add controller runtime PM support for v3 hw scsi: hisi_sas: Add the check of the definition of method _PS0 and _PR0 scsi: hisi_sas: Add device link between SCSI devices and hisi_hba scsi: hisi_sas: Filter out new PHYs up events during suspended scsi: hisi_sas: Recover phys state according to the status before reset drivers/scsi/hisi_sas/Kconfig | 1 + drivers/scsi/hisi_sas/hisi_sas.h | 2 + drivers/scsi/hisi_sas/hisi_sas_main.c | 10 ++- drivers/scsi/hisi_sas/hisi_sas_v3_hw.c | 105 +++++++++++++++++++++++-- 4 files changed, 107 insertions(+), 11 deletions(-) -- 2.26.2
