2024-06-20block: Add core atomic write supportJohn Garry
Add atomic write support, as follows: - add helper functions to get request_queue atomic write limits - report request_queue atomic write support limits to sysfs and update Doc - support to safely merge atomic writes - deal with splitting atomic writes - misc helper functions - add a per-request atomic write flag New request_queue limits are added, as follows: - atomic_write_hw_max is set by the block driver and is the maximum length of an atomic write which the device may support. It is not necessarily a power-of-2. - atomic_write_max_sectors is derived from atomic_write_hw_max_sectors and max_hw_sectors. It is always a power-of-2. Atomic writes may be merged, and atomic_write_max_sectors would be the limit on a merged atomic write request size. This value is not capped at max_sectors, as the value in max_sectors can be controlled from userspace, and it would only cause trouble if userspace could limit atomic_write_unit_max_bytes and the other atomic write limits. - atomic_write_hw_unit_{min,max} are set by the block driver and are the min/max length of an atomic write unit which the device may support. They both must be a power-of-2. Typically atomic_write_hw_unit_max will hold the same value as atomic_write_hw_max. - atomic_write_unit_{min,max} are derived from atomic_write_hw_unit_{min,max}, max_hw_sectors, and block core limits. Both min and max values must be a power-of-2. - atomic_write_hw_boundary is set by the block driver. If non-zero, it indicates an LBA space boundary at which an atomic write straddles no longer is atomically executed by the disk. The value must be a power-of-2. Note that it would be acceptable to enforce a rule that atomic_write_hw_boundary_sectors is a multiple of atomic_write_hw_unit_max, but the resultant code would be more complicated. All atomic writes limits are by default set 0 to indicate no atomic write support. Even though it is assumed by Linux that a logical block can always be atomically written, we ignore this as it is not of particular interest. Stacked devices are just not supported either for now. An atomic write must always be submitted to the block driver as part of a single request. As such, only a single BIO must be submitted to the block layer for an atomic write. When a single atomic write BIO is submitted, it cannot be split. As such, atomic_write_unit_{max, min}_bytes are limited by the maximum guaranteed BIO size which will not be required to be split. This max size is calculated by request_queue max segments and the number of bvecs a BIO can fit, BIO_MAX_VECS. Currently we rely on userspace issuing a write with iovcnt=1 for pwritev2() - as such, we can rely on each segment containing PAGE_SIZE of data, apart from the first+last, which each can fit logical block size of data. The first+last will be LBS length/aligned as we rely on direct IO alignment rules also. New sysfs files are added to report the following atomic write limits: - atomic_write_unit_max_bytes - same as atomic_write_unit_max_sectors in bytes - atomic_write_unit_min_bytes - same as atomic_write_unit_min_sectors in bytes - atomic_write_boundary_bytes - same as atomic_write_hw_boundary_sectors in bytes - atomic_write_max_bytes - same as atomic_write_max_sectors in bytes Atomic writes may only be merged with other atomic writes and only under the following conditions: - total resultant request length <= atomic_write_max_bytes - the merged write does not straddle a boundary Helper function bdev_can_atomic_write() is added to indicate whether atomic writes may be issued to a bdev. If a bdev is a partition, the partition start must be aligned with both atomic_write_unit_min_sectors and atomic_write_hw_boundary_sectors. FSes will rely on the block layer to validate that an atomic write BIO submitted will be of valid size, so add blk_validate_atomic_write_op_size() for this purpose. Userspace expects an atomic write which is of invalid size to be rejected with -EINVAL, so add BLK_STS_INVAL for this. Also use BLK_STS_INVAL for when a BIO needs to be split, as this should mean an invalid size BIO. Flag REQ_ATOMIC is used for indicating an atomic write.

2024-06-19block: move cache control settings out of queue->flagsChristoph Hellwig
Move the cache control settings into the queue_limits so that the flags can be set atomically with the device queue frozen. Add new features and flags field for the driver set flags, and internal (usually sysfs-controlled) flags in the block layer. Note that we'll eventually remove enough field from queue_limits to bring it back to the previous size. The disable flag is inverted compared to the previous meaning, which means it now survives a rescan, similar to the max_sectors and max_discard_sectors user limits. The FLUSH and FUA flags are now inherited by blk_stack_limits, which simplified the code in dm a lot, but also causes a slight behavior change in that dm-switch and dm-unstripe now advertise a write cache despite setting num_flush_bios to 0. The I/O path will handle this gracefully, but as far as I can tell the lack of num_flush_bios and thus flush support is a pre-existing data integrity bug in those targets that really needs fixing, after which a non-zero num_flush_bios should be required in dm for targets that map to underlying devices.

2024-06-14block: move integrity information into queue_limitsChristoph Hellwig
Move the integrity information into the queue limits so that it can be set atomically with other queue limits, and that the sysfs changes to the read_verify and write_generate flags are properly synchronized. This also allows to provide a more useful helper to stack the integrity fields, although it still is separate from the main stacking function as not all stackable devices want to inherit the integrity settings. Even with that it greatly simplifies the code in md and dm. Note that the integrity field is moved as-is into the queue limits. While there are good arguments for removing the separate blk_integrity structure, this would cause a lot of churn and might better be done at a later time if desired. However the integrity field in the queue_limits structure is now unconditional so that various ifdefs can be avoided or replaced with IS_ENABLED(). Given that tiny size of it that seems like a worthwhile trade off. Signed-off-by: Christoph Hellwig <hch@lst.de> Reviewed-by: Hannes Reinecke <hare@suse.de> Reviewed-by: Martin K.

2024-06-07dt-bindings: HID: i2c-hid: elan: add 'no-reset-on-power-off' propertyJohan Hovold
When the power supply is shared with other peripherals the reset line can be wired in such a way that it can remain deasserted regardless of whether the supply is on or not. This is important as it can be used to avoid holding the controller in reset for extended periods of time when it remains powered, something which can lead to increased power consumption. Leaving reset deasserted also avoids leaking current through the reset circuitry pull-up resistors. Add a new 'no-reset-on-power-off' devicetree property which can be used by the OS to determine when reset needs to be asserted on power down. Note that this property can also be used when the supply cannot be turned off by the OS at all.

2024-06-07dt-bindings: HID: i2c-hid: add dedicated Ilitek ILI2901 schemaJohan Hovold
The Ilitek ILI2901 touch screen controller was apparently incorrectly added to the Elan eKTH6915 schema simply because it also has a reset gpio and is currently managed by the Elan driver in Linux. The two controllers are not related even if an unfortunate wording in the commit message adding the Ilitek compatible made it sound like they were. Add a dedicated schema for the ILI2901 which does not specify the I2C address (which is likely 0x41 rather than 0x10 as for other Ilitek touch controllers) to avoid cluttering the Elan schema with unrelated devices and to make it easier to find the correct schema when adding further Ilitek controllers.

2024-06-06kconfig: doc: document behavior of 'select' and 'imply' followed by 'if'Masahiro Yamada
Documentation/kbuild/kconfig-language.rst explains the behavior of 'select' as follows: reverse dependencies can be used to force a lower limit of another symbol. The value of the current menu symbol is used as the minimal value <symbol> can be set to. This is not true when the 'select' property is followed by 'if'. [Test Code] config MODULES def_bool y modules config A def_tristate y select C if B config B def_tristate m config C tristate [Result] CONFIG_MODULES=y CONFIG_A=y CONFIG_B=m CONFIG_C=m If "the value of A is used as the minimal value C can be set to", C must be 'y'. The actual behavior is "C is selected by (A && B)". The lower limit of C is downgraded due to B being 'm'. This behavior is kind of weird, and this has arisen several times in the mailing list. I do not know whether it is a bug or intended behavior. Anyway, it is not feasible to change it now because many Kconfig files are written based on this behavior. The same applies to 'imply'.

We're stuck supporting scalar misaligned loads in userspace because they were part of the ISA at the time we froze the uABI. That wasn't the case for vector misaligned accesses, so depending on them unconditionally is a userspace bug. All extant vector hardware traps on these misaligned accesses.

2024-05-30netdev: add qstat for csum completeJakub Kicinski
Recent commit 0cfe71f45f42 ("netdev: add queue stats") added a lot of useful stats, but only those immediately needed by virtio. Presumably virtio does not support CHECKSUM_COMPLETE, so statistic for that form of checksumming wasn't included. Other drivers will definitely need it, in fact we expect it to be needed in net-next soon (mlx5). So let's add the definition of the counter for CHECKSUM_COMPLETE to uAPI in net already, so that the counters are in a more natural order (all subsequent counters have not been present in any released kernel, yet).

2024-05-27platform/x86: touchscreen_dmi: Add support for setting touchscreen ↵Hans de Goede
properties from cmdline On x86/ACPI platforms touchscreens mostly just work without needing any device/model specific configuration. But in some cases (mostly with Silead and Goodix touchscreens) it is still necessary to manually specify various touchscreen-properties on a per model basis. touchscreen_dmi is a special place for DMI quirks for this, but it can be challenging for users to figure out the right property values, especially for Silead touchscreens where non of these can be read back from the touchscreen-controller. ATM users can only test touchscreen properties by editing touchscreen_dmi.c and then building a completely new kernel which makes it unnecessary difficult for users to test and submit properties when necessary for their laptop / tablet model. Add support for specifying properties on the kernel commandline to allow users to easily figure out the right settings. See the added documentation in kernel-parameters.txt for the commandline syntax.
