* move asm/unaligned.h to linux/unaligned.hAl Viro2024-10-021-1/+1
| | | | | | | | | | | | | | | | | | | asm/unaligned.h is always an include of asm-generic/unaligned.h; might as well move that thing to linux/unaligned.h and include that - there's nothing arch-specific in that header. auto-generated by the following: for i in `git grep -l -w asm/unaligned.h`; do sed -i -e "s/asm\/unaligned.h/linux\/unaligned.h/" $i done for i in `git grep -l -w asm-generic/unaligned.h`; do sed -i -e "s/asm-generic\/unaligned.h/linux\/unaligned.h/" $i done git mv include/asm-generic/unaligned.h include/linux/unaligned.h git mv tools/include/asm-generic/unaligned.h tools/include/linux/unaligned.h sed -i -e "/unaligned.h/d" include/asm-generic/Kbuild sed -i -e "s/__ASM_GENERIC/__LINUX/" include/linux/unaligned.h tools/include/linux/unaligned.h

* fpga: Simplify and improve fpga region test using deferred actionsMarco Pagani2024-08-141-17/+24
| | | | | | | | | | | | | | | Use deferred actions to simplify the test suite and avoid potential memory leaks when test cases fail. Remove unnecessary calls to kunit_device_unregister() since kunit devices are tied to the test context and released by a deferred action when the test is completed.

Lots of stuff in here, with not a huge diffstat, but apis are evolving which required lots of files to be touched. Highlights of the changes in here are: - platform remove callback api final fixups (Uwe took many releases to get here, finally!) - Rust bindings for basic firmware apis and initial driver-core interactions. It's not all that useful for a "write a whole driver in rust" type of thing, but the firmware bindings do help out the phy rust drivers, and the driver core bindings give a solid base on which others can start their work. There is still a long way to go here before we have a multitude of rust drivers being added, but it's a great first step. - driver core const api changes. This reached across all bus types, and there are some fix-ups for some not-common bus types that linux-next and 0-day testing shook out. This work is being done to help make the rust bindings more safe, as well as the C code, moving toward the end-goal of allowing us to put driver structures into read-only memory. We aren't there yet, but are getting closer. - minor devres cleanups and fixes found by code inspection - arch_topology minor changes - other minor driver core cleanups All of these have been in linux-next for a very long time with no reported problems" * tag 'driver-core-6.11-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core: (55 commits) ARM: sa1100: make match function take a const pointer sysfs/cpu: Make crash_hotplug attribute world-readable dio: Have dio_bus_match() callback take a const * zorro: make match function take a const pointer driver core: module: make module_[add|remove]_driver take a const * driver core: make driver_find_device() take a const * driver core: make driver_[create|remove]_file take a const * firmware_loader: fix soundness issue in `request_internal` firmware_loader: annotate doctests as `no_run` devres: Correct code style for functions that return a pointer type devres: Initialize an uninitialized struct member devres: Fix memory leakage caused by driver API devm_free_percpu() devres: Fix devm_krealloc() wasting memory driver core: platform: Switch to use kmemdup_array() driver core: have match() callback in struct bus_type take a const * MAINTAINERS: add Rust device abstractions to DRIVER CORE device: rust: improve safety comments MAINTAINERS: add Danilo as FIRMWARE LOADER maintainer MAINTAINERS: add Rust FW abstractions to FIRMWARE LOADER firmware: rust: improve safety comments ...
| * driver core: have match() callback in struct bus_type take a const *Greg Kroah-Hartman2024-07-031-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In the match() callback, the struct device_driver * should not be changed, so change the function callback to be a const *. This is one step of many towards making the driver core safe to have struct device_driver in read-only memory. Because the match() callback is in all busses, all busses are modified to handle this properly. This does entail switching some container_of() calls to container_of_const() to properly handle the constant *. For some busses, like PCI and USB and HV, the const * is cast away in the match callback as those busses do want to modify those structures at this point in time (they have a local lock in the driver structure.) That will have to be changed in the future if they wish to have their struct device * in read-only-memory. Cc: Rafael J.

| * | fpga: region: add owner module and take its refcountMarco Pagani2024-04-231-10/+14

This approach is problematic since it can lead to a null pointer dereference while attempting to get the region during programming if the parent device does not have a driver. To address this problem, add a module owner pointer to the fpga_region struct and use it to take the module's refcount. Modify the functions for registering a region to take an additional owner module parameter and rename them to avoid conflicts. Use the old function names for helper macros that automatically set the module that registers the region as the owner. This ensures compatibility with existing low-level control modules and reduces the chances of registering a region without setting the owner. Also, update the documentation to keep it consistent with the new interface for registering an fpga region.

|/ | | | | | | | | | | | | | | | Add PCI subdevice ID for the Intel D5005 Stratix 10 FPGA card as used with the Open FPGA Stack (OFS) FPGA Interface Manager (FIM). Unlike the Intel D5005 PAC FIM which exposed a separate PCI device ID, the OFS FIM reuses the same device ID for all DFL-based FPGA cards and differentiates on the subdevice ID. The subdevice ID values were chosen as the numeric part of the FPGA card names in hexadecimal.

| * fpga: altera-fpga2sdram: Convert to platform remove callback returning voidUwe Kleine-König2023-12-211-4/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is ignored (apart from emitting a warning) and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new(), which already returns void. Eventually after all drivers are converted, .remove_new() will be renamed to .remove(). Trivially convert this driver from always returning zero in the remove callback to the void returning variant.

| * drivers/fpga: use standard array-copy functionPhilipp Stanner2023-11-171-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | dfl.c utilizes memdup_user() and array_size() to copy a userspace array. array_size() will likely never trigger thanks to the preceding check. Nevertheless, in the theoretical event that it would, it would return SIZE_MAX to memdup_user(), resulting in an attempt to allocate huge amounts of memory. string.h from the core-api now provides memdup_array_user() which also performs an overflow check and returns an error-pointer with -EOVERFLOW to the caller. As an additional advantage it standardizes how userspace-arrays are being copied and, thus, makes it more obvious to readers that an array is being copied. Replace memdup_user() with memdup_array_user().

|/ | | | | | | | | | | | | | | Ever since the eventfd type was introduced back in 2007 in commit e1ad7468c77d ("signal/timer/event: eventfd core") the eventfd_signal() function only ever passed 1 as a value for @n. There's no point in keeping that additional argument.

| * fpga: versal: Add support for 44-bit DMA operationsNava kishore Manne2023-10-161-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | The existing implementation support only 32-bit DMA operation. So, it fails to load the bitstream for the high DDR designs(Beyond 4GB). To fix this issue update the DMA mask handling logic to support 44-bit DMA operations.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Use preferred spi_get_device_match_data() instead of of_match_device() and spi_get_device_id() to get the driver match data. With this, adjust the includes to explicitly include the correct headers. Also drop of_match_ptr for of_ef_match, which is not necessary because DT is always used for this driver.
