2025-05-07cpufreq/sched: schedutil: Add helper for governor checksRafael J. Wysocki
Add a helper for checking if schedutil is the current governor for a given cpufreq policy and use it in sched_is_eas_possible() to avoid accessing cpufreq policy internals directly from there. No intentional functional impact. Signed-off-by: Rafael J.

2025-05-07dt-bindings: clock: thead: Add TH1520 VO clock controllerMichal Wilczynski
Add device tree bindings for the TH1520 Video Output (VO) subsystem clock controller. The VO sub-system manages clock gates for multimedia components including HDMI, MIPI, and GPU. Document the VIDEO_PLL requirements for the VO clock controller, which receives its input from the AP clock controller. The VIDEO_PLL is a Silicon Creations Sigma-Delta (integer) PLL typically running at 792 MHz with maximum FOUTVCO of 2376 MHz. This binding complements the existing AP sub-system clock controller which manages CPU, DPU, GMAC and TEE PLLs.

2025-05-07irqdomain: Add IRQ_DOMAIN_FLAG_MSI_IMMUTABLE and irq_domain_is_msi_immutable()Frank Li
Add the flag IRQ_DOMAIN_FLAG_MSI_IMMUTABLE and the API function irq_domain_is_msi_immutable() to check if the MSI controller retains an immutable address/data pair during irq_set_affinity(). Ensure compatibility with MSI users like PCIe Endpoint Doorbell, which require the address/data pair to remain unchanged after setup. Use this function to verify if the MSI controller is immutable.

2025-05-06io_uring: enable per-io write streamsKeith Busch
Allow userspace to pass a per-I/O write stream in the SQE: __u8 write_stream; The __u8 type matches the size the filesystems and block layer support. Application can query the supported values from the block devices max_write_streams sysfs attribute. Unsupported values are ignored by file operations that do not support write streams or rejected with an error by those that support them.

2025-05-06block: add new helper for disabling elevator switch when deleting diskMing Lei
Add new helper disable_elv_switch() and new flag QUEUE_FLAG_NO_ELV_SWITCH for disabling elevator switch before deleting disk: - originally flag QUEUE_FLAG_REGISTERED is added for preventing elevator switch during removing disk, but this flag has been used widely for other purposes, so add one new flag for disabling elevator switch only - for avoiding deadlock risk, we have to move elevator queue register/unregister out of elevator lock and queue freeze, which will be done in next patch. However, this way adds small race window between elevator switch and deleting ->queue_kobj, in which elevator queue register/unregister could be run concurrently. The added helper will be used for avoiding the race in the following patch. - drain in-progress elevator switch before deleting disk Suggested-by: Nilay Shroff <nilay@linux.ibm.com> Reviewed-by: Christoph Hellwig <hch@lst.de> Reviewed-by: Hannes Reinecke <hare@suse.de> Signed-off-by: Ming Lei <ming.lei@redhat.com> Reviewed-by: Nilay Shroff <nilay@linux.ibm.com> Link: https://lore.kernel.org/r/20250505141805.2751237-21-ming.lei@redhat.com Signed-off-by: Jens Axboe <axboe@kernel.dk>
2025-05-06block: prevent adding/deleting disk during updating nr_hw_queuesMing Lei
Both adding/deleting disk code are reader of `nr_hw_queues`, so we can't allow them in-progress when updating nr_hw_queues, kernel panic and kasan has been reported in [1]. Prevent adding/deleting disk during updating nr_hw_queues by adding rw_semaphore to tagset, write lock is grabbed in blk_mq_update_nr_hw_queues(), and read lock is acquired when adding/deleting disk. Also mark GFP_NOIO allocation scope for adding/deleting disk because blk_mq_update_nr_hw_queues() is part of some driver's error handler. This way avoids lot of trouble.

2025-05-06media: common: Add v4l2_find_nearest_size_conditional()Sakari Ailus
v4l2_find_nearest_size() returns a mode from sensor driver's mode list that is a best match width and height wise for the sensor. Some drivers have different set of available modes depending on the number of lanes. While this could be handled within a driver by providing different lists of modes, provide a helper v4l2_find_nearest_size_conditional() to ignore modes that aren't available. Also use size_t for the array index and remove extra commas while at it. Signed-off-by: Sakari Ailus <sakari.ailus@linux.intel.com> Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl>
