2022-09-24media: cx88: add IR remote support for NotOnlyTV LV3HDaniel González Cabanelas
The PCI hybrid card NotOnlyTV LV3H has a built-in IR receiver connected via I2C bus, currently not supported. This receiver is probably present in more Geniatech cards. It has no capability for repeating when a key is held down. Add support for this built-in IR receiver. Use the existing Total Media In Hand_02 remote keytable (Geniatech Mygica X8507) which matches exactly the LV3H remote.

2022-09-24media: mc: entity: Rewrite media_pipeline_start()Laurent Pinchart
[Note: the code is mostly from Laurent but the patch description is from Tomi] The media_pipeline_start() and media_pipeline_stop() functions use the media graph walk API to traverse the graph and validate the pipeline. The graph walk traverses the media graph following links between the entities. Also, while the pipeline can't change between the start and stop calls, the graph is walked again from scratch at stop time, or any time a driver needs to inspect the pipeline. With the upcoming multiplexed streams support we will need a bit more intelligent pipeline construction, as e.g. two independent streams may be passing through a single entity via separate pads in which case those pads should not be part of the same pipeline. This patch essentially rewrites the media_pipeline_start/stop so that a pipeline is defined as a set of pads instead of entities and the media graph traversal considers the pad interdependencies when choosing which links to follow. Currently all the entity's pads are considered as interdependent. This means that the behavior with all the current drivers stays the same, but in the future we can define a more fine-grained pipeline construction. Additionally the media pipeline's pads are cached at media_pipeline_start() time, and re-used at media_pipeline_stop() which avoid the need to re-walk the whole graph as the previous implementation did. Also, caching pads in the pipeline can serve in the future as the foundation to provide a better API than the media graph walk to drivers to iterate over pads and entities in the pipeline. Note that the old media_pipeline_start/stop used the media graph walk API. The new version does not use the media graph walk API, but instead a new implementation. There are two reasons for not changing the graph walk: it proved to be rather difficult to change the graph walk to have the features implemented in this patch, and second, this keeps the backward compatibility of the graph walk as there are users of the graph walk API The long term plan is that all the existing code would be converted to use the new cached pipeline, thus allowing us to remove the graph walk.

2022-09-24media: mc: entity: add alloc variant of pipeline_startTomi Valkeinen
Add new variant of media_pipeline_start(), media_pipeline_alloc_start(). media_pipeline_alloc_start() can be used by drivers that do not need to extend the media_pipeline. The function will either use the pipeline already associated with the entity, if such exists, or allocate a new pipeline. When media_pipeline_stop() is called and the pipeline's use count drops to zero, the pipeline is automatically freed.

2022-09-24media: v4l2-dev: Add videodev wrappers for media pipelinesTomi Valkeinen
With the upcoming stream related improvements to the pipelines, the pipelines are moved from media entities to media pads. As the drivers currently use the pipelines with the entity based model, moving the pipelines to pads will cause changes to the drivers. However, most of the uses of media pipelines are related to a video device (a DMA engine) with a single pad, and thus there's never a need to support multiple pads in these use cases. We can avoid pushing the complexities of the pad based model to the drivers by adding video device wrappers for the pipeline related functions. This patch adds a number of wrappers to media_pipeline functions, all of which take a video_device as a parameter (instead of a media_entity), and verify that there's just one pad.

V4L2_FRAME_DESC_ENTRY_MAX is currently set to 4. In theory it's possible to have an arbitrary amount of streams in a single pad, so preferably there should be no hardcoded maximum number. However, I believe a reasonable max is 8, which would cover a CSI-2 pad with 4 streams of pixel data and 4 streams of metadata.

2022-09-24vfs: add vfs_tmpfile_open() helperMiklos Szeredi
This helper unifies tmpfile creation with opening. Existing vfs_tmpfile() callers outside of fs/namei.c will be converted to using this helper. There are two such callers: cachefile and overlayfs. The cachefiles code currently uses the open_with_fake_path() helper to open the tmpfile, presumably to disable accounting of the open file. Overlayfs uses tmpfile for copy_up, which means these struct file instances will be short lived, hence it doesn't really matter if they are accounted or not. Disable accounting in this helper too, which should be okay for both callers. Add MAY_OPEN permission checking for consistency. Like for create(2) read/write permissions are not checked.

START_USER_RECOVERY and END_USER_RECOVERY are two new control commands to support user recovery feature. After a crash, user should send START_USER_RECOVERY, it will: (1) check if (a)current ublk_device is UBLK_S_DEV_QUIESCED which was set by quiesce_work and (b)chardev is released (2) reinit all ubqs, including: (a) put the task_struct and reset ->ubq_daemon to NULL. (b) reset all ublk_io. (3) reset ub->mm to NULL. Then, user should start a new process and send FETCH_REQ on each ubq_daemon. Finally, user should send END_USER_RECOVERY, it will: (1) wait for all new ubq_daemons getting ready. (2) update ublksrv_pid (3) unquiesce the request queue and expect incoming ublk_queue_rq() (4) convert ub's state to UBLK_S_DEV_LIVE Note: we can handle STOP_DEV between START_USER_RECOVERY and END_USER_RECOVERY.

2022-09-23vmlinux.lds.h: CFI: Reduce alignment of jump-table to function alignmentWill Deacon
Due to undocumented, hysterical raisins on x86, the CFI jump-table sections in .text are needlessly aligned to PMD_SIZE in the vmlinux linker script. When compiling a CFI-enabled arm64 kernel with a 64KiB page-size, a PMD maps 512MiB of virtual memory and so the .text section increases to a whopping 940MiB and blows the final Image up to 960MiB. Others report a link failure. Since the CFI jump-table requires only instruction alignment, reduce the alignment directives to function alignment for parity with other parts of the .text section. This reduces the size of the .text section for the aforementioned 64KiB page size arm64 kernel to 19MiB for a much more reasonable total Image size of 39MiB.

resctrl_arch_rmid_read() returns a value in chunks, as read from the hardware. This needs scaling to bytes by mon_scale, as provided by the architecture code. Now that resctrl_arch_rmid_read() performs the overflow and corrections itself, it may as well return a value in bytes directly. This allows the accesses to the architecture specific 'hw' structure to be removed. Move the mon_scale conversion into resctrl_arch_rmid_read(). mbm_bw_count() is updated to calculate bandwidth from bytes.

2022-09-23x86/resctrl: Rename and change the units of resctrl_cqm_thresholdJames Morse
resctrl_cqm_threshold is stored in a hardware specific chunk size, but exposed to user-space as bytes. This means the filesystem parts of resctrl need to know how the hardware counts, to convert the user provided byte value to chunks. The interface between the architecture's resctrl code and the filesystem ought to treat everything as bytes. Change the unit of resctrl_cqm_threshold to bytes. resctrl_arch_rmid_read() still returns its value in chunks, so this needs converting to bytes. As all the users have been touched, rename the variable to resctrl_rmid_realloc_threshold, which describes what the value is for. Neither r->num_rmid nor hw_res->mon_scale are guaranteed to be a power of 2, so the existing code introduces a rounding error from resctrl's theoretical fraction of the cache usage. This behaviour is kept as it ensures the user visible value matches the value read from hardware when the rmid will be reallocated.

2022-09-23x86/resctrl: Pass the required parameters into resctrl_arch_rmid_read()James Morse
resctrl_arch_rmid_read() is intended as the function that an architecture agnostic resctrl filesystem driver can use to read a value in bytes from a hardware register. Currently the function returns the MBM values in chunks directly from hardware. To convert this to bytes, some correction and overflow calculations are needed. These depend on the resource and domain structures. Overflow detection requires the old chunks value. None of this is available to resctrl_arch_rmid_read(). MPAM requires the resource and domain structures to find the MMIO device that holds the registers. Pass the resource and domain to resctrl_arch_rmid_read(). This makes rmid_dirty() too big. Instead merge it with its only caller, and the name is kept as a local variable.

2022-09-23x86/resctrl: Abstract __rmid_read()James Morse
__rmid_read() selects the specified eventid and returns the counter value from the MSR. The error handling is architecture specific, and handled by the callers, rdtgroup_mondata_show() and __mon_event_count(). Error handling should be handled by architecture specific code, as a different architecture may have different requirements. MPAM's counters can report that they are 'not ready', requiring a second read after a short delay. This should be hidden from resctrl. Make __rmid_read() the architecture specific function for reading a counter. Rename it resctrl_arch_rmid_read() and move the error handling into it. A read from a counter that hardware supports but resctrl does not now returns -EINVAL instead of -EIO from the default case in __mon_event_count(). It isn't possible for user-space to see this change as resctrl doesn't expose counters it doesn't support.

This change adds support for not enabling carrier during TUNSETIFF interface creation by specifying the IFF_NO_CARRIER flag. Our tests make heavy use of tun interfaces. In some scenarios, the test process creates the interface but another process brings it up after the interface is discovered via netlink notification. In that case, it is not possible to create a tun/tap interface with carrier off without it racing against the bring up. Immediately setting carrier off via TUNSETCARRIER is still too late.
