dma-buf: make kobj_type structure constant

2023-02-17T08:16:34Z

Since commit ee6d3dd4ed48 ("driver core: make kobj_type constant.") the driver core allows the usage of const struct kobj_type. Take advantage of this to constify the structure definition to prevent modification at runtime.

dma-buf: actually set signaling bit for private stub fences

2023-02-01T10:17:34Z

In dma_fence_allocate_private_stub() set the signaling bit of the newly allocated private stub fence rather than the signaling bit of the shared dma_fence_stub.

Merge v6.2-rc6 into drm-next

2023-01-31T11:23:23Z

Due to holidays we started -next with more -fixes in-flight than usual, and people have been asking where they are. Backmerge to get things better in sync. Conflicts: - Tiny conflict in drm_fbdev_generic.c between variable rename and missing error handling that got added. - Conflict in drm_fb_helper.c between the added call to vgaswitcheroo in drm_fb_helper_single_fb_probe and a refactor patch that extracted lots of helpers and incidentally removed the dev local variable. Readd it to make things compile. Signed-off-by: Daniel Vetter

Pull driver core updates from Greg KH: "Here is the set of driver core and kernfs changes for 6.2-rc1. The "big" change in here is the addition of a new macro, container_of_const() that will preserve the "const-ness" of a pointer passed into it. The "problem" of the current container_of() macro is that if you pass in a "const *", out of it can comes a non-const pointer unless you specifically ask for it. For many usages, we want to preserve the "const" attribute by using the same call. For a specific example, this series changes the kobj_to_dev() macro to use it, allowing it to be used no matter what the const value is. This prevents every subsystem from having to declare 2 different individual macros (i.e. kobj_const_to_dev() and kobj_to_dev()) and having the compiler enforce the const value at build time, which having 2 macros would not do either. The driver for all of this have been discussions with the Rust kernel developers as to how to properly mark driver core, and kobject, objects as being "non-mutable". The changes to the kobject and driver core in this pull request are the result of that, as there are lots of paths where kobjects and device pointers are not modified at all, so marking them as "const" allows the compiler to enforce this. So, a nice side affect of the Rust development effort has been already to clean up the driver core code to be more obvious about object rules. All of this has been bike-shedded in quite a lot of detail on lkml with different names and implementations resulting in the tiny version we have in here, much better than my original proposal. Lots of subsystem maintainers have acked the changes as well. Other than this change, included in here are smaller stuff like: - kernfs fixes and updates to handle lock contention better - vmlinux.lds.h fixes and updates - sysfs and debugfs documentation updates - device property updates All of these have been in the linux-next tree for quite a while with no problems" * tag 'driver-core-6.2-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core: (58 commits) device property: Fix documentation for fwnode_get_next_parent() firmware_loader: fix up to_fw_sysfs() to preserve const usb.h: take advantage of container_of_const() device.h: move kobj_to_dev() to use container_of_const() container_of: add container_of_const() that preserves const-ness of the pointer driver core: fix up missed drivers/s390/char/hmcdrv_dev.c class.devnode() conversion. driver core: fix up missed scsi/cxlflash class.devnode() conversion. driver core: fix up some missing class.devnode() conversions. driver core: make struct class.devnode() take a const * driver core: make struct class.dev_uevent() take a const * cacheinfo: Remove of_node_put() for fw_token device property: Add a blank line in Kconfig of tests device property: Rename goto label to be more precise device property: Move PROPERTY_ENTRY_BOOL() a bit down device property: Get rid of __PROPERTY_ENTRY_ARRAY_EL*SIZE*() kernfs: fix all kernel-doc warnings and multiple typos driver core: pass a const * into of_device_uevent() kobject: kset_uevent_ops: make name() callback take a const * kobject: kset_uevent_ops: make filter() callback take a const * kobject: make kobject_namespace take a const * ...

Pull drm updates from Dave Airlie: "The biggest highlight is that the accel subsystem framework is merged. Hopefully for 6.3 we will be able to line up a driver to use it. In drivers land, i915 enables DG2 support by default now, and nouveau has a big stability refactoring and initial ampere support, AMD includes new hw IP support and should build on ARM again. There is also an ofdrm driver to take over offb on platforms it's used. Stuff outside my tree, the dma-buf patches hit a few places, the vc4 firmware changes also do, and i915 has some interactions with MEI for discrete GPUs.

dma-buf: fix dma_buf_export init order v2

2022-12-13T07:31:45Z

The init order and resulting error handling in dma_buf_export was pretty messy. Subordinate objects like the file and the sysfs kernel objects were initializing and wiring itself up with the object in the wrong order resulting not only in complicating and partially incorrect error handling, but also in publishing only halve initialized DMA-buf objects. Clean this up thoughtfully by allocating the file independent of the DMA-buf object. Then allocate and initialize the DMA-buf object itself, before publishing it through sysfs. If everything works as expected the file is then connected with the DMA-buf object and publish it through debugfs. Also adds the missing dma_resv_fini() into the error handling. v2: add some missing changes to dma_bug_getfile() and a missing NULL check in dma_buf_file_release() Signed-off-by: Christian König Reviewed-by: Michael J.
