2024-03-11soc: sunxi: sram: export register 0 for THS on H616Andre Przywara
The Allwinner H616 SoC contains a mysterious bit at register offset 0x0 in the SRAM control block. If bit 16 is set (the reset value), the temperature readings of the THS are way off, leading to reports about 200C, at normal ambient temperatures. Clearing this bits brings the reported values down to the expected values. The BSP code clears this bit in firmware (U-Boot), and has an explicit comment about this, but offers no real explanation. Experiments in U-Boot show that register 0x0 has no effect on the SRAM C visibility: all tested bit settings still allow full read and write access by the CPU to the whole of SRAM C. Only bit 24 of the register at offset 0x4 makes all of SRAM C inaccessible by the CPU. So modelling the THS switch functionality as an SRAM region would not reflect reality. Since we should not rely on firmware settings, allow other code (the THS driver) to access this register, by exporting it through the already existing regmap. This mimics what we already do for the LDO control and the EMAC register. To avoid concurrent accesses to the same register at the same time, by the SRAM switch code and the regmap code, use the same lock to protect the access. The regmap subsystem allows to use an existing lock, so we just need to hook in there.

2024-03-11mm: Introduce vmap_page_range() to map pages in PCI address spaceAlexei Starovoitov
ioremap_page_range() should be used for ranges within vmalloc range only. The vmalloc ranges are allocated by get_vm_area(). PCI has "resource" allocator that manages PCI_IOBASE, IO_SPACE_LIMIT address range, hence introduce vmap_page_range() to be used exclusively to map pages in PCI address space.

2024-03-10scsi: lpfc: Define types in a union for generic void *context3 ptrJustin Tee
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.

2024-03-10scsi: lpfc: Define lpfc_dmabuf type for ctx_buf ptrJustin Tee
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.
