Pull driver core updates from Danilo Krummrich:
"Arch Topology:
- Move parse_acpi_topology() from arm64 to common code for reuse in
RISC-V
CPU:
- Expose housekeeping CPUs through /sys/devices/system/cpu/housekeeping
- Print a newline (or 0x0A) instead of '(null)' reading
/sys/devices/system/cpu/nohz_full when nohz_full= is not set
debugfs
- Remove (broken) 'no-mount' mode
- Remove redundant access mode checks in debugfs_get_tree() and
debugfs_create_*() functions
Devres:
- Remove unused devm_free_percpu() helper
- Move devm_alloc_percpu() from device.h to devres.h
Firmware Loader:
- Replace simple_strtol() with kstrtoint()
- Do not call cancel_store() when no upload is in progress
kernfs:
- Increase struct super_block::maxbytes to MAX_LFS_FILESIZE
- Fix a missing unwind path in __kernfs_new_node()
Misc:
- Increase the name size in struct auxiliary_device_id to 40
characters
- Replace system_unbound_wq with system_dfl_wq and add WQ_PERCPU to
alloc_workqueue()
Platform:
- Replace ERR_PTR() with IOMEM_ERR_PTR() in platform ioremap
functions
Rust:
- Auxiliary:
- Unregister auxiliary device on parent device unbind
- Move parent() to impl Device; implement device context aware
parent() for Device<Bound>
- Illustrate how to safely obtain a driver's device private data
when calling from an auxiliary driver into the parant device
driver
- DebugFs:
- Implement support for binary large objects
- Device:
- Let probe() return the driver's device private data as pinned
initializer, i.e. impl PinInit<Self, Error>
- Implement safe accessor for a driver's device private data for
Device<Bound> (returned reference can't out-live driver binding
and guarantees the correct private data type)
- Implement AsBusDevice trait, to be used by class device
abstractions to derive the bus device type of the parent device
- DMA:
- Store raw pointer of allocation as NonNull
- Use start_ptr() and start_ptr_mut() to inherit correct
mutability of self
- FS:
- Add file::Offset type alias
- I2C:
- Add abstractions for I2C device / driver infrastructure
- Implement abstractions for manual I2C device registrations
- I/O:
- Use "kernel vertical" style for imports
- Define ResourceSize as resource_size_t
- Move ResourceSize to top-level I/O module
- Add type alias for phys_addr_t
- Implement Rust version of read_poll_timeout_atomic()
- PCI:
- Use "kernel vertical" style for imports
- Move I/O and IRQ infrastructure to separate files
- Add support for PCI interrupt vectors
- Implement TryInto<IrqRequest<'a>> for IrqVector<'a> to convert
an IrqVector bound to specific pci::Device into an IrqRequest
bound to the same pci::Device's parent Device
- Leverage pin_init_scope() to get rid of redundant Result in IRQ
methods
- PinInit:
- Add {pin_}init_scope() to execute code before creating an
initializer
- Platform:
- Leverage pin_init_scope() to get rid of redundant Result in IRQ
methods
- Timekeeping:
- Implement abstraction of udelay()
- Uaccess:
- Implement read_slice_partial() and read_slice_file() for
UserSliceReader
- Implement write_slice_partial() and write_slice_file() for
UserSliceWriter
sysfs:
- Prepare the constification of struct attribute"
* tag 'driver-core-6.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/driver-core/driver-core: (75 commits)
rust: pci: fix build failure when CONFIG_PCI_MSI is disabled
debugfs: Fix default access mode config check
debugfs: Remove broken no-mount mode
debugfs: Remove redundant access mode checks
driver core: Check drivers_autoprobe for all added devices
driver core: WQ_PERCPU added to alloc_workqueue users
driver core: replace use of system_unbound_wq with system_dfl_wq
tick/nohz: Expose housekeeping CPUs in sysfs
tick/nohz: avoid showing '(null)' if nohz_full= not set
sysfs/cpu: Use DEVICE_ATTR_RO for nohz_full attribute
kernfs: fix memory leak of kernfs_iattrs in __kernfs_new_node
fs/kernfs: raise sb->maxbytes to MAX_LFS_FILESIZE
mod_devicetable: Bump auxiliary_device_id name size
sysfs: simplify attribute definition macros
samples/kobject: constify 'struct foo_attribute'
samples/kobject: add is_visible() callback to attribute group
sysfs: attribute_group: enable const variants of is_visible()
sysfs: introduce __SYSFS_FUNCTION_ALTERNATIVE()
sysfs: transparently handle const pointers in ATTRIBUTE_GROUPS()
sysfs: attribute_group: allow registration of const attribute
