| | | * | scsi: lpfc: Define lpfc_nodelist type for ctx_ndlp ptrJustin Tee2024-03-107-39/+36
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In LPFC_MBOXQ_t data structure, the ctx_ndlp ptr shouldn't be defined as a generic void *ptr. It is named ctx_ndlp and it should only be used as an lpfc_nodelist *ptr. Due to the void* declaration, there have been abuses of ctx_ndlp for things not related to ndlp. So, set the ptr type for *ctx_ndlp as lpfc_nodelist. Remove all type casts on ctx_ndlp because it is no longer a void *ptr. Convert the abuse of ctx_ndlp for things not related to ndlps to use the void *context3 ptr.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | To reduce usage of and contention for hbalock, a separate dedicated lock is used to protect ras_fwlog state.

| | | * | scsi: lpfc: Release hbalock before calling lpfc_worker_wake_up()Justin Tee2024-03-103-20/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | lpfc_worker_wake_up() calls the lpfc_work_done() routine, which takes the hbalock. Thus, lpfc_worker_wake_up() should not be called while holding the hbalock to avoid potential deadlock.

| | | * | scsi: lpfc: Update lpfc_ramp_down_queue_handler() logicJustin Tee2024-03-102-10/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Typically when an out of resource CQE status is detected, the lpfc_ramp_down_queue_handler() logic is called to help reduce I/O load by reducing an sdev's queue_depth. However, the current lpfc_rampdown_queue_depth() logic does not help reduce queue_depth. num_cmd_success is never updated and is always zero, which means new_queue_depth will always be set to sdev->queue_depth. So, new_queue_depth = sdev->queue_depth - new_queue_depth always sets new_queue_depth to zero. And, scsi_change_queue_depth(sdev, 0) is essentially a no-op. Change the lpfc_ramp_down_queue_handler() logic to set new_queue_depth equal to sdev->queue_depth subtracted from number of times num_rsrc_err was incremented. If num_rsrc_err is >= sdev->queue_depth, then set new_queue_depth equal to 1. Eventually, the frequency of Good_Status frames will signal SCSI upper layer to auto increase the queue_depth back to the driver default of 64 via scsi_handle_queue_ramp_up().

| | | * | scsi: lpfc: Remove IRQF_ONESHOT flag from threaded IRQ handlingJustin Tee2024-03-101-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | IRQF_ONESHOT is found to mask HBA generated interrupts when thread_fn is running. As a result, some EQEs/CQEs miss timely processing resulting in SCSI layer attempts to abort commands due to io_timeout. Abort CQEs are also not processed leading to the observations of hangs and spam of "0748 abort handler timed out waiting for aborting I/O" log messages. Remove the IRQF_ONESHOT flag. The cmpxchg and xchg atomic operations on lpfc_queue->queue_claimed already protect potential parallel access to an EQ/CQ should the thread_fn get interrupted by the primary irq handler.

| | | * | scsi: lpfc: Move NPIV's transport unregistration to after resource clean upJustin Tee2024-03-101-4/+4

This occurs when a vport is unregistered before the Remove All DA_ID CT and LOGO ELS are sent to the fabric. Currently fc_remove_host(), which calls dev_loss_tmo for all D_IDs including the fabric D_ID, removes the last ndlp reference and frees the ndlp rport object. This sometimes causes the race condition where the final DA_ID and LOGO are skipped from being sent to the fabric switch. Fix by moving the fc_remove_host() and scsi_remove_host() calls after DA_ID and LOGO are sent.

This can cause problems if another process has locked the hub to remove it or change its configuration: Removing the hub or changing its configuration requires the hub interface to be removed, which requires the port device to be removed, and device_del() waits until all outstanding sysfs attribute callbacks for the ports have returned. The lock can't be released until then. But the disable_show() or disable_store() routine can't return until after it has acquired the lock. The resulting deadlock can be avoided by calling sysfs_break_active_protection(). This will cause the sysfs core not to wait for the attribute's callback routine to return, allowing the removal to proceed. The disadvantage is that after making this call, there is no guarantee that the hub structure won't be deallocated at any moment. To prevent this, we have to acquire a reference to it first by calling hub_get().

Additionally, move 8 bits from reserved_1 to features in the ucsi_capability struct. This makes the field 16 bits, still 8 short of the 24 bits allocated for it in UCSI v3.0, but it will not overflow because UCSI only defines 14 bits in bmOptionalFeatures.

The current quirk still leaves room for races because it requires two consecutive ACK commands to be sent. Refactor and significantly simplify the quirk to fix this: Send a dummy command and bundle the connector change ack with the command completion ack in a single UCSI_ACK_CC_CI command. This removes the need to probe for the quirk. While there define flag bits for struct ucsi_acpi->flags in ucsi_acpi.c and don't re-use definitions from ucsi.h for struct ucsi->flags.

For host mode, if the controller goes through the dwc3 code path, then a child xHCI platform device is created. Make sure the platform device also inherits the wakeup setting for xHCI to enable remote wakeup. For device mode, make sure to disable system wakeup if no gadget driver is bound. We may experience unwanted system wakeup due to the wakeup signal from the controller PMU detecting connection/disconnection when in low power (D3). E.g. In the case of Steam Deck, the PCI PME prevents the system staying in suspend. Cc: stable@vger.kernel.org Reported-by: Guilherme G.
