Changes to a plane's type after it has been registered aren't propagated to userspace automatically.

2025-02-14drm/atomic: Let drivers decide which planes to async flipAndré Almeida1-1/+2
Currently, DRM atomic uAPI allows only primary planes to be flipped asynchronously. However, each driver might be able to perform async flips in other different plane types. To enable drivers to set their own restrictions on which type of plane they can or cannot flip, use the existing atomic_async_check() from struct drm_plane_helper_funcs to enhance this flexibility, thus allowing different plane types to be able to do async flips as well. Create a new parameter for the atomic_async_check(), `bool flip`. This parameter is used to distinguish when this function is being called from a plane update from a full page flip. In order to prevent regressions and such, we keep the current policy: we skip the driver check for the primary plane, because it is always allowed to do async flips on it.

2024-12-02Get rid of 'remove_new' relic from platform driver structLinus Torvalds10-10/+10
The continual trickle of small conversion patches is grating on me, and is really not helping. Just get rid of the 'remove_new' member function, which is just an alias for the plain 'remove', and had a comment to that effect: /* * .remove_new() is a relic from a prototype conversion of .remove(). * New drivers are supposed to implement .remove(). Once all drivers are * converted to not use .remove_new any more, it will be dropped. */ This was just a tree-wide 'sed' script that replaced '.remove_new' with '.remove', with some care taken to turn a subsequent tab into two tabs to make things line up. I did do some minimal manual whitespace adjustment for places that used spaces to line things up. Then I just removed the old (sic) .remove_new member function, and this is the end result. No more unnecessary conversion noise. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

gitolite.kernel.org:pub/scm/linux/kernel/git/vfs/vfs Pull misc vfs updates from Christian Brauner: "This contains the usual pile of misc updates: Features: - Add F_CREATED_QUERY fcntl() that allows userspace to query whether a file was actually created. Often userspace wants to know whether an O_CREATE request did actually create a file without using O_EXCL. The current logic is that to first attempts to open the file without O_CREAT | O_EXCL and if ENOENT is returned userspace tries again with both flags. If that succeeds all is well. If it now reports EEXIST it retries. That works fairly well but some corner cases make this more involved. If this operates on a dangling symlink the first openat() without O_CREAT | O_EXCL will return ENOENT but the second openat() with O_CREAT | O_EXCL will fail with EEXIST. The reason is that openat() without O_CREAT | O_EXCL follows the symlink while O_CREAT | O_EXCL doesn't for security reasons. So it's not something we can really change unless we add an explicit opt-in via O_FOLLOW which seems really ugly. All available workarounds are really nasty (fanotify, bpf lsm etc) so add a simple fcntl(). - Try an opportunistic lookup for O_CREAT. Today, when opening a file we'll typically do a fast lookup, but if O_CREAT is set, the kernel always takes the exclusive inode lock. This was likely done with the expectation that O_CREAT means that we always expect to do the create, but that's often not the case. Many programs set O_CREAT even in scenarios where the file already exists (see related F_CREATED_QUERY patch motivation above). The series contained in the pr rearranges the pathwalk-for-open code to also attempt a fast_lookup in certain O_CREAT cases. If a positive dentry is found, the inode_lock can be avoided altogether and it can stay in rcuwalk mode for the last step_into. - Expose the 64 bit mount id via name_to_handle_at() Now that we provide a unique 64-bit mount ID interface in statx(2), we can now provide a race-free way for name_to_handle_at(2) to provide a file handle and corresponding mount without needing to worry about racing with /proc/mountinfo parsing or having to open a file just to do statx(2). While this is not necessary if you are using AT_EMPTY_PATH and don't care about an extra statx(2) call, users that pass full paths into name_to_handle_at(2) need to know which mount the file handle comes from (to make sure they don't try to open_by_handle_at a file handle from a different filesystem) and switching to AT_EMPTY_PATH would require allocating a file for every name_to_handle_at(2) call - Add a per dentry expire timeout to autofs There are two fairly well known automounter map formats, the autofs format and the amd format (more or less System V and Berkley). Some time ago Linux autofs added an amd map format parser that implemented a fair amount of the amd functionality. This was done within the autofs infrastructure and some functionality wasn't implemented because it either didn't make sense or required extra kernel changes. The idea was to restrict changes to be within the existing autofs functionality as much as possible and leave changes with a wider scope to be considered later. One of these changes is implementing the amd options: 1) "unmount", expire this mount according to a timeout (same as the current autofs default). 2) "nounmount", don't expire this mount (same as setting the autofs timeout to 0 except only for this specific mount) . 3) "utimeout=<seconds>", expire this mount using the specified timeout (again same as setting the autofs timeout but only for this mount) To implement these options per-dentry expire timeouts need to be implemented for autofs indirect mounts. This is because all map keys (mounts) for autofs indirect mounts use an expire timeout stored in the autofs mount super block info. structure and all indirect mounts use the same expire timeout. Fixes: - Fix missing fput for FSCONFIG_SET_FD in autofs - Use param->file for FSCONFIG_SET_FD in coda - Delete the 'fs/netfs' proc subtreee when netfs module exits - Make sure that struct uid_gid_map fits into a single cacheline - Don't flush in-flight wb switches for superblocks without cgroup writeback - Correcting the idmapping mount example in the idmapping documentation - Fix a race between evice_inodes() and find_inode() and iput() - Refine the show_inode_state() macro definition in writeback code - Prevent dump_mapping() from accessing invalid dentry.d_name.name - Show actual source for debugfs in /proc/mounts - Annotate data-race of busy_poll_usecs in eventpoll - Don't WARN for racy path_noexec check in exec code - Handle OOM on mnt_warn_timestamp_expiry() - Fix some spelling in the iomap design documentation - Fix typo in procfs comment - Fix typo in fs/namespace.c comment Cleanups: - Add the VFS git tree to the MAINTAINERS file - Move FMODE_UNSIGNED_OFFSET to fop_flags freeing up another f_mode bit in struct file bringing us to 5 free f_mode bits - Remove the __I_DIO_WAKEUP bit from i_state flags as we can simplify the wait mechanism - Remove the unused path_put_init() helper - Replace a __u32 with u32 for s_fsnotify_mask as __u32 is uapi specific - Replace the unsigned long i_state member with a u32 i_state member in struct inode freeing up 4 bytes in struct inode.

Commit <17de3f5fdd35> ("iommu: Retire bus ops") removes iommu ops from the bus structure. The iommu subsystem no longer relies on bus for operations. So iommu_domain_alloc() interface is no longer relevant. Replace iommu_domain_alloc() with iommu_paging_domain_alloc() which takes the physical device from which the host1x_device virtual device was instantiated. This physical device is a common parent to all physical devices that are part of the virtual device.

2024-08-29drm/tegra: gem: Don't attach dma-bufs when not neededMikko Perttunen2-30/+57
The dma-buf import code currently attaches and maps all imported dma-bufs to the drm device to get their sgt for mapping to the directly managed IOMMU domain. In many cases, like for newer chips (Tegra186+), the directly managed IOMMU domain is, however, not used. Mapping to the drm device can also cause issues e.g. with swiotlb since it is not a real device. To improve the situation, only attach and map imported dma-bufs when required.

2024-07-08drm/tegra: Call drm_atomic_helper_shutdown() at shutdown timeDouglas Anderson1-0/+6
Based on grepping through the source code this driver appears to be missing a call to drm_atomic_helper_shutdown() at system shutdown time. Among other things, this means that if a panel is in use that it won't be cleanly powered off at system shutdown time. The fact that we should call drm_atomic_helper_shutdown() in the case of OS shutdown/restart comes straight out of the kernel doc "driver instance overview" in drm_drv.c.
