Once again, a busy development cycle, with lots of changes happening in the driver core in the quest to be able to move "struct bus" and "struct class" into read-only memory, a task now complete with these changes. This will make the future rust interactions with the driver core more "provably correct" as well as providing more obvious lifetime rules for all busses and classes in the kernel. The changes required for this did touch many individual classes and busses as many callbacks were changed to take const * parameters instead. All of these changes have been submitted to the various subsystem maintainers, giving them plenty of time to review, and most of them actually did so. Other than those changes, included in here are a small set of other things: - kobject logging improvements - cacheinfo improvements and updates - obligatory fw_devlink updates and fixes - documentation updates - device property cleanups and const * changes - firwmare loader dependency fixes. All of these have been in linux-next for a while with no reported problems" * tag 'driver-core-6.4-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core: (120 commits) device property: make device_property functions take const device * driver core: update comments in device_rename() driver core: Don't require dynamic_debug for initcall_debug probe timing firmware_loader: rework crypto dependencies firmware_loader: Strip off \n from customized path zram: fix up permission for the hot_add sysfs file cacheinfo: Add use_arch[|_cache]_info field/function arch_topology: Remove early cacheinfo error message if -ENOENT cacheinfo: Check cache properties are present in DT cacheinfo: Check sib_leaf in cache_leaves_are_shared() cacheinfo: Allow early level detection when DT/ACPI info is missing/broken cacheinfo: Add arm64 early level initializer implementation cacheinfo: Add arch specific early level initializer tty: make tty_class a static const structure driver core: class: remove struct class_interface * from callbacks driver core: class: mark the struct class in struct class_interface constant driver core: class: make class_register() take a const * driver core: class: mark class_release() as taking a const * driver core: remove incorrect comment for device_create* MIPS: vpe-cmp: remove module owner pointer from struct class usage. ... 2023-04-11T22:20:20+00:00 Florian Fainelli f.fainelli@gmail.com 2023-04-02T13:54:14+00:00 urn:sha1:b645fc696bec7653f3396e933015dd8728bbb10f Newline characters will be taken into account for the firmware search path parameter, warn users about that and provide an example using 'echo -n' such that it clarifies the typical use of that parameter.

In order to avoid this in the future we should document some expectations around linux-firmware.

For example, FPGA based PCIe cards load firmware and FPGA images from local FLASH when the card boots. The images in FLASH may be updated with new images provided by the user at his/her convenience. A device driver may call firmware_upload_register() to expose persistent "loading" and "data" sysfs files. These files are used in the same way as the fallback sysfs "loading" and "data" files. When 0 is written to "loading" to complete the write of firmware data, the data is transferred to the lower-level driver using pre-registered call-back functions. The data transfer is done in the context of a kernel worker thread.
