2024-09-10block: Prevent deadlocks when switching elevatorsDamien Le Moal
Commit af2814149883 ("block: freeze the queue in queue_attr_store") changed queue_attr_store() to always freeze a sysfs attribute queue before calling the attribute store() method, to ensure that no IOs are in-flight when an attribute value is being updated. However, this change created a potential deadlock situation for the scheduler queue attribute as changing the queue elevator with elv_iosched_store() can result in a call to request_module() if the user requested module is not already registered. If the file of the requested module is stored on the block device of the frozen queue, a deadlock will happen as the read operations triggered by request_module() will wait for the queue freeze to end. Solve this issue by introducing the load_module method in struct queue_sysfs_entry, and to calling this method function in queue_attr_store() before freezing the attribute queue. The macro definition QUEUE_RW_LOAD_MODULE_ENTRY() is added to define a queue sysfs attribute that needs loading a module. The definition of the scheduler atrribute is changed to using QUEUE_RW_LOAD_MODULE_ENTRY(), with the function elv_iosched_load_module() defined as the load_module method. elv_iosched_store() can then be simplified to remove the call to request_module().

2024-09-10drm/tegra: Use iommu_paging_domain_alloc()Lu Baolu
Commit <17de3f5fdd35> ("iommu: Retire bus ops") removes iommu ops from the bus structure. The iommu subsystem no longer relies on bus for operations. So iommu_domain_alloc() interface is no longer relevant. Replace iommu_domain_alloc() with iommu_paging_domain_alloc() which takes the physical device from which the host1x_device virtual device was instantiated. This physical device is a common parent to all physical devices that are part of the virtual device.

2024-09-10ACPI: CPPC: Add support for setting EPP register in FFHMario Limonciello
Some Asus AMD systems are reported to not be able to change EPP values because the BIOS doesn't advertise support for the CPPC MSR and the PCC region is not configured. However the ACPI 6.2 specification allows CPC registers to be declared in FFH: ``` Starting with ACPI Specification 6.2, all _CPC registers can be in PCC, System Memory, System IO, or Functional Fixed Hardware address spaces. OSPM support for this more flexible register space scheme is indicated by the “Flexible Address Space for CPPC Registers” _OSC bit. ``` If this _OSC has been set allow using FFH to configure EPP.

2024-09-10Bluetooth: replace deprecated strncpy with strscpy_padJustin Stitt
strncpy() is deprecated for use on NUL-terminated destination strings [0] and as such we should prefer more robust and less ambiguous string interfaces. The CAPI (part II) [1] states that the manufacturer id should be a "zero-terminated ASCII string" and should "always [be] zero-terminated." Much the same for the serial number: "The serial number, a seven-digit number coded as a zero-terminated ASCII string". Along with this, its clear the original author intended for these buffers to be NUL-padded as well. To meet the specification as well as properly NUL-pad, use strscpy_pad(). In doing this, an opportunity to simplify this code is also present. Remove the min_t() and combine the length check into the main if.

2024-09-10Bluetooth: Use led_set_brightness() in LED trigger activate() callbackHans de Goede
A LED trigger's activate() callback gets called when the LED trigger gets activated for a specific LED, so that the trigger code can ensure the LED state matches the current state of the trigger condition (LED_FULL when HCI_UP is set in this case). led_trigger_event() is intended for trigger condition state changes and iterates over _all_ LEDs which are controlled by this trigger changing the brightness of each of them. In the activate() case only the brightness of the LED which is being activated needs to change and that LED is passed as an argument to activate(), switch to led_set_brightness() to only change the brightness of the LED being activated.

The former is for initial setup including setting baud rates, downloading fw, starting chip and etc, while the latter is for dumping firmware versions and setting public address after firmware updates and normal startup.

2024-09-10btrfs: only unlock the to-be-submitted ranges inside a folioQu Wenruo
[SUBPAGE COMPRESSION LIMITS] Currently inside writepage_delalloc(), if a delalloc range is going to be submitted asynchronously (inline or compression, the page dirty/writeback/unlock are all handled in at different time, not at the submission time), then we return 1 and extent_writepage() will skip the submission. This is fine if every sector matches page size, but if a sector is smaller than page size (aka, subpage case), then it can be very problematic, for example for the following 64K page: 0 16K 32K 48K 64K |/| |///////| |/| | | 4K 52K Where |/| is the dirty range we need to submit. In the above case, we need the following different handling for the 3 ranges: - [0, 4K) needs to be submitted for regular write A single sector cannot be compressed. - [16K, 32K) needs to be submitted for compressed write - [48K, 52K) needs to be submitted for regular write. Above, if we try to submit [16K, 32K) for compressed write, we will return 1 and immediately, and without submitting the remaining [48K, 52K) range. Furthermore, since extent_writepage() will exit without unlocking any sectors, the submitted range [0, 4K) will not have sector unlocked. That's the reason why for now subpage is only allowed for full page range. [ENHANCEMENT] - Introduce a submission bitmap at btrfs_bio_ctrl::submit_bitmap This records which sectors will be submitted by extent_writepage_io(). This allows us to track which sectors needs to be submitted thus later to be properly unlocked. For asynchronously submitted range (inline/compression), the corresponding bits will be cleared from that bitmap. - Only return 1 if no sector needs to be submitted in writepage_delalloc() - Only submit sectors marked by submission bitmap inside extent_writepage_io() So we won't touch the asynchronously submitted part. - Introduce btrfs_folio_end_writer_lock_bitmap() helper This will only unlock the involved sectors specified by @bitmap parameter, to avoid touching the range asynchronously submitted. Please note that, since subpage compression is still limited to page aligned range, this change is only a preparation for future sector perfect compression support for subpage.

2024-09-10btrfs: remove btrfs_folio_end_all_writers()Qu Wenruo
The function btrfs_folio_end_all_writers() is only utilized in extent_writepage() as a way to unlock all subpage range (for both successful submission and error handling). Meanwhile we have a similar function, btrfs_folio_end_writer_lock(). The difference is, btrfs_folio_end_writer_lock() expects a range that is a subset of the already locked range. This limit on btrfs_folio_end_writer_lock() is a little overkilled, preventing it from being utilized for error paths. So here we enhance btrfs_folio_end_writer_lock() to accept a superset of the locked range, and only end the locked subset. This means we can replace btrfs_folio_end_all_writers() with btrfs_folio_end_writer_lock() instead.
