The new qTimestamp attribute was added to UFS 4.0 spec, in order to synchronize timestamp between device logs and the host. The spec recommends to send this attribute upon device power-on Reset/HW reset or when switching to Active state (using SSU command). Due to this attribute, the attribute's max value was extended to 8 bytes. As a result, the new definition of struct utp_upiu_query_v4_0 was added. Signed-off-by:

The variable phba->fcf.fcf_flag is often protected by the lock phba->hbalock() when is accessed. Here is an example in lpfc_unregister_fcf_rescan(): spin_lock_irq(&phba->hbalock); phba->fcf.fcf_flag |= FCF_INIT_DISC; spin_unlock_irq(&phba->hbalock); However, in the same function, phba->fcf.fcf_flag is assigned with 0 without holding the lock, and thus can cause a data race: phba->fcf.fcf_flag = 0; To fix this possible data race, a lock and unlock pair is added when accessing the variable phba->fcf.fcf_flag.

Reading the 800+ pages of SPC often leads to a brain shutdown and to less than ideal code...

Replace this with a comment describing the cases we are interested in and replace the if-else code block with a simple test of the cdlp field that is used as the function return value. Reported-by:

One-element arrays are deprecated, and we are replacing them with flexible array members instead. So, replace one-element arrays with flexible-array members in a couple of structures, and refactor the rest of the code, accordingly. This helps with the ongoing efforts to tighten the FORTIFY_SOURCE routines on memcpy(). This results in no differences in binary output.

To improve this, only annotate the one uint64_t field inside of lpfc_name as packed, with an explicit 4-byte alignment, as is the default already on the 32-bit x86 ABI but not on most others. With this, the other __packed annotations can be removed again, as this avoids the incorrect padding. Two other structures change their layout as a result of this change: - struct _LOGO never gained a __packed annotation even though it has the same alignment problem as the others but is not used anywhere in the driver today. - struct serv_param similarly has this issue, and it is used, my guess is that this is only an internal structure rather than part of a binary interface, so the padding has no negative effect here.

Martin Wilck <mwilck@suse.com> says: This patch series addresses some issues we saw in a test setup with a large number of SCSI LUNs. The first two patches simply increase the number of available sg and bsg devices. 3-5 fix a large delay we encountered between blocking a Fibre Channel remote port and the dev_loss_tmo. 6 renames scsi_target_block() to scsi_block_targets(), and makes additional changes to this API, as suggested in the review of the v2 series. 7 improves a warning message.

All callers (fc_remote_port_delete(), __iscsi_block_session(), __srp_start_tl_fail_timers(), srp_reconnect_rport(), snic_tgt_del()) pass parent devices of scsi_target devices to scsi_target_block(). Rename the function to scsi_block_targets(), and simplify it by assuming that it is always passed a parent device. Also, have callers pass the Scsi_Host pointer to scsi_block_targets(), as every caller has this pointer readily available. Suggested-by:

scsi_device_block() is only called from scsi_target_block(), which calls it repeatedly for every child device. For targets with many devices, waiting for every queue to quiesce may cause a substantial delay (we measured more than 100s delay for blocking a FC rport with 2048 LUNs). Just call blk_mq_wait_quiesce_done() once from scsi_target_block() after stopping all queues. Signed-off-by:

Martin Wilck authored
scsi_stop_queue() has just two callers, one with and one without "nowait". As blk_mq_quiesce_queue() comes down to blk_mq_quiesce_queue_nowait() followed by blk_mq_wait_quiesce_done(), we might as well open-code this in scsi_device_block(). Also, add a comment explaining why blk_mq_quiesce_queue_nowait() must be called with the state_mutex held, see https://lore.kernel.org/linux-scsi/3b8b13bf-a458-827a-b916-07d7eee8ae00@acm.org/.

There are three flags that control Write Booster Feature: 1. WB ON/OFF 2. WB Hibern Flush ON/OFF (implicitly) 3. WB Flush ON/OFF (explicit) In the case of "Hibern Flush", one of the conditions for flush WB buffer is that avail_wb_buff < wb_flush_threshold. As we know, different users have different requirements for power consumption and performance. Therefore, we need the ability to manually set wb_flush_threshold, so that users can easily and flexibly adjust the wb_flush_threshold value, thereby achieving a balance between power consumption and performance. So the sysfs attribute that controls this is necessary. wb_flush_threshold represents the threshold for flushing WB buffer, whose value expressed in unit of 10% granularity, such as '1' representing 10%, '2' representing 20%, and so on.

Now that there is a new dedicated ICE driver, drop the ufs-qcom-ice and use the new ICE api provided by the Qualcomm soc driver ice. The platforms that already have ICE support will use the API as library since there will not be a devicetree node, but instead they have reg range. In this case, the of_qcom_ice_get will return an ICE instance created for the consumer's device. But if there are platforms that do not have ice reg in the consumer devicetree node and instead provide a dedicated ICE devicetree node, the of_qcom_ice_get will look up the device based on qcom,ice property and will get the ICE instance registered by the probe function of the ice driver. The ICE clock is now handle by the new driver. This is done by enabling it on the creation of the ICE instance and then enabling/disabling it on UFS runtime resume/suspend. Signed-off-by:
