For v3 hw we will add support for runtime PM which is only supported in new framework. Legacy PM support and new framework are not allowed to be used together. Switch to new framework to support suspend and resume. Link: https://lore.kernel.org/r/1601649038-25534-3-git-send-email-john.garry@huawei.comSigned-off-by:

A call trace is observed when running function level reset with online CPUs less than 16 and MSI auto-affinity enabled. [16538.348038] Call trace: [16538.348422] pci_irq_vector+0x98/0xc0 [16538.348947] disable_host_v3_hw+0x8c/0x288 [hisi_sas_v3_hw] [16538.349706] hisi_sas_reset_prepare_v3_hw+0x60/0x88 [hisi_sas_v3_hw] [16538.350631] pci_dev_save_and_disable+0x38/0x68 [16538.351290] pci_reset_function+0x44/0x88 [16538.351846] reset_store+0x6c/0xb8 [16538.352429] dev_attr_store+0x44/0x60 [16538.353035] sysfs_kf_write+0x58/0x80 [16538.353558] kernfs_fop_write+0x140/0x230 [16538.354175] __vfs_write+0x48/0x80 [16538.354675] vfs_write+0xb8/0x1d8 [16538.355145] ksys_write+0x74/0xf8 [16538.355615] __arm64_sys_write+0x24/0x30 [16538.356240] el0_svc_common.constprop.4+0x80/0x1f0 [16538.356905] do_el0_svc+0x2c/0x38 [16538.357408] el0_svc+0x14/0x40 [16538.357848] el0_sync_handler+0xbc/0x2ec [16538.358388] el0_sync+0x140/0x180 The reason is that if we use pci_alloc_irq_vectors_affinity() to allocate IRQs, the number of CQ IRQs can only be less than or equal to the number of online CPUs, but we use hisi_hba->queue_count (always 16) to iterate during interrupt_disable_v3_hw(). Use hisi_hba->cq_nvecs to replace hisi_hba->queue_count to avoid synchronize IRQ on a CPU which does not exist.

The be_fill_queue() function can only fail when "eq_vaddress" is NULL and since it's non-NULL here that means the function call can't fail. But imagine if it could, then in that situation we would want to store the "paddr" so that dma memory can be released.

The fnic drivers assigns an ioreq structure to each command and severs this assignment once scsi_done() has been called and the command has been completed. When traversing commands to terminate outstanding I/O we should not call scsi_done() on commands which do not have a corresponding ioreq structure; these commands have either never entered the driver or have already been completed.

Some iSCSI targets went with the traditional "export N ports" approach and then allowed the initiator to multipath over them. Other targets went the opposite direction and export a single port, and then software on the target side performs load balancing and failover to other targets via an iSCSI specific feature or IP takover. The problem for the 2nd type of config is we quickly run out of our five retries and get I/O errors. In these setups we want to reduce resource use on the initiator side so we only wanted the one session and no dm-multipath. To handle traditional multipath operations like failover we do IP takover on the target side. So we would have an iSCSI target running on node1. Some monitoring software decides it's dead or the node is overloaded so it starts the iSCSI target on node2. The problem is for the failover case where we might have the equivalent of a dm-multipath temporary all paths down, or we just have to try more than 5 nodes before finding a good one. To handle this type of issue allow the user to configure the disk cmd retries from -1 to the current max of 5. -1 means infinite retries and should be used for setups where some other setting is going to control when to fail. For example iSCSI has the replacement/recovery timeout and fc (some users have used FC with NPIV and done something similar as IP takover) has dev_loss_tmo/fast_io_fail which will eventually expire and fail I/O.

Driver was using a shorter timeout waiting for PLOGI from the peer in point-to-point configurations. Some devices takes some time (~4 seconds) to initiate the PLOGI. This peer initiating PLOGI is when the peer has a higher P-WWN. Increase the wait time based on N2N R_A_TOV. Link: https://lore.kernel.org/r/20200929102152.32278-7-njavali@marvell.comReviewed-by:

Normally, the MPI firmware is reset when an MPI dump is collected. If an unsaved MPI dump exists in the driver, though, an alternate mechanism is used. This mechanism, which was not fully correct, is not recommended and instead an MPI dump template walk is suggested to perform the MPI reset. To allow for the MPI dump template walk, extra space is reserved in the MPI dump buffer which gets used only when there is already an MPI dump in place.

The high-performance mode will be enabled if all below conditions are well-declaired in device tree, - Proper platform-specific compatible string which enables the host capability "UFS_MTK_CAP_BOOST_CRYPT_ENGINE". - "dvfsrc-vcore" node is available in this platform. - Required minimum vcore voltage for high-performance mode. - Clock mux and clock parents of inline encryption engine for both "low-power mode" and "high-performance mode".
