2024-03-11drm/i915: Show bios vbt when read from firmware/spi/opromRadhakrishna Sripada
Make debugfs vbt only shows valid vbt when read from ACPI opregion. Make it work when read from firmware/spi/pci oprom cases.

In LPFC_MBOXQ_t, the void *context3 ptr is used for various paths. It is treated as a generic pointer, and is type casted during its usage. The issue with this is that it can sometimes get confusing when reading code as to what the context3 ptr is being used for and mistakenly be reused in a different context. Rename context3 to ctx_u, and declare it as a union of defined ptr types. From now on, the ctx_u ptr may be used only if users define the use case type.

In LPFC_MBOXQ_t, the ctx_buf ptr shouldn't be defined as a generic void *ptr. It is named ctx_buf and it should only be used as an lpfc_dmabuf *ptr. Due to the void* declaration, there have been abuses of ctx_buf for things not related to lpfc_dmabuf. So, set the ptr type for *ctx_buf as lpfc_dmabuf. Remove all type casts on ctx_buf because it is no longer a void *ptr. Convert the abuse of ctx_buf for something not related to lpfc_dmabuf to use the void *context3 ptr. A particular abuse of the ctx_buf warranted a new void *ext_buf ptr. However, the usage of this new void *ext_buf is not generic. It is intended to only hold virtual addresses for extended mailbox commands.

2024-03-10scsi: lpfc: Update lpfc_ramp_down_queue_handler() logicJustin Tee
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().

2024-03-10scsi: lpfc: Remove IRQF_ONESHOT flag from threaded IRQ handlingJustin Tee
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.

2024-03-10scsi: lpfc: Move NPIV's transport unregistration to after resource clean upJustin Tee
There are cases after NPIV deletion where the fabric switch still believes the NPIV is logged into the fabric. 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.
