2025-07-03media: pisp_be: Fix pm_runtime underrun in probeJacopo Mondi
During the probe() routine, the PiSP BE driver needs to power up the interface in order to identify and initialize the hardware. The driver resumes the interface by calling the pispbe_runtime_resume() function directly, without going through the pm_runtime helpers, but later suspends it by calling pm_runtime_put_autosuspend(). This causes a PM usage count imbalance at probe time, notified by the runtime_pm framework with the below message in the system log: pispbe 1000880000.pisp_be: Runtime PM usage count underflow! Fix this by resuming the interface using the pm runtime helpers instead of calling the resume function directly and use the pm_runtime framework in the probe() error path. While at it, remove manual suspend of the interface in the remove() function. The driver cannot be unloaded if in use, so simply disable runtime pm. To simplify the implementation, make the driver depend on PM as the RPI5 platform where the ISP is integrated in uses the PM framework by default.

2025-07-03media: pisp_be: Split jobs creation and schedulingJacopo Mondi
Currently the 'pispbe_schedule()' function does two things: 1) Tries to assemble a job by inspecting all the video node queues to make sure all the required buffers are available 2) Submit the job to the hardware The pispbe_schedule() function is called at: - video device start_streaming() time - video device qbuf() time - irq handler As assembling a job requires inspecting all queues, it is a rather time consuming operation which is better not run in IRQ context. To avoid executing the time consuming job creation in interrupt context split the job creation and job scheduling in two distinct operations. When a well-formed job is created, append it to the newly introduced 'pispbe->job_queue' where it will be dequeued from by the scheduling routine. As the per-node 'ready_queue' buffer list is only accessed in vb2 ops callbacks, protected by the node->queue_lock mutex, it is not necessary to guard it with a dedicated spinlock so drop it. Also use the spin_lock_irq() variant in all functions not called from an IRQ context where the spin_lock_irqsave() version was used.

2025-07-03media: pisp_be: Remove config validation from schedule()Jacopo Mondi
The config parameters buffer is already validated in pisp_be_validate_config() at .buf_prepare() time. However some of the same validations are also performed at pispbe_schedule() time. In particular the function checks that: 1) config.num_tiles is valid 2) At least one of the BAYER or RGB input is enabled The input config validation is already performed in pisp_be_validate_config() and while job.hw_enables is modified by pispbe_xlate_addrs(), the function only resets the input masks if - there is no input buffer available, but pispbe_prepare_job() fails before calling pispbe_xlate_addrs() in this case - bayer_enable is 0, but in this case rgb_enable is valid as guaranteed by pisp_be_validate_config() - only outputs are reset in rgb_enable For this reasons there is no need to repeat the check at pispbe_schedule() time. The num_tiles validation can be moved to pisp_be_validate_config() as well. As num_tiles is a u32 it can'be be < 0, so change the sanity check accordingly.

2025-06-18media: nxp: imx8-isi: Simplify a couple of error messagesKrzysztof Hałasa
The error messages in the mxc_isi_crossbar_enable_streams() and mxc_isi_crossbar_disable_streams() functions are similar, with a single word difference between them. The word is moved out of the format string to a separate dev_err() argument to try and save memory through string de-duplication. The total savings are however small, as the .data size reduction is partly offset by a .text size increase, with a total saving of 8 bytes in total on an ARM64 platforms. They also come at the cost of making the error message difficult to grep, which outweights the gains. Simplify the error messages to make them grep-able.

2025-06-18media: vsp1: Add VSPX supportJacopo Mondi
Add support for VSPX, a specialized version of the VSP2 that transfers data to the ISP. The VSPX is composed of two RPF units to read data from external memory and an IIF instance that performs transfer towards the ISP. The VSPX is supported through a newly introduced vsp1_vspx.c file that exposes two interfaces: vsp1_vspx interface, declared in vsp1_vspx.h for the vsp1 core to initialize and cleanup the VSPX, and a vsp1_isp interface, declared in include/media/vsp1.h for the ISP driver to control the VSPX operations.

2025-06-18media: rcar-vin: Check for correct capture interrupt eventNiklas Söderlund
Depending on if the capture session deals with fields or whole frames interrupts can be generated at an end of field, or end of frame event. The interrupt mask is setup to generate an interrupt on one of the two events depending on what is needed when the VIN is started. The end of field bit is set in both cases so controlling the mask that generates an interrupt have been enough to control the two use-cases. Before extending the interrupt handler to deal with other types of interrupt events it is needs to extended to "capture complete" check for correct the use-case in operation. Without this the simplification in the handler can result in corrupted frames when the mask on what type of events can generate an interrupt generated can no longer be assumed to only be an "capture complete" event. Which bit is checked matches which bit is enabled at configuration time as which event can generate an interrupt for "capture complete". There is no functional change. While at it switch to use the BIT() macro to describe the bit positions for the interrupt functions.

2025-06-17media: raspberrypi: cfe: Fix min_reqbufs_allocationTomi Valkeinen
The driver checks if "vq->max_num_buffers + *nbuffers < 3", but vq->max_num_buffers is (by default) 32, so the check is never true. Nor does the check make sense. The original code in the BSP kernel was "vq->num_buffers + *nbuffers < 3", but got mangled along the way to upstream. The intention was to make sure that at least 3 buffers are allocated. Fix this by removing the bad lines and setting q->min_reqbufs_allocation to three.
