Add initial media request support: 1) Add MEDIA_IOC_REQUEST_ALLOC ioctl support to media-device.c 2) Add struct media_request to store request objects. 3) Add struct media_request_object to represent a request object. 4) Add MEDIA_REQUEST_IOC_QUEUE/REINIT ioctl support. Basic lifecycle: the application allocates a request, adds objects to it, queues the request, polls until it is completed and can then read the final values of the objects at the time of completion. When it closes the file descriptor the request memory will be freed (actually, when the last user of that request releases the request). Drivers will bind an object to a request (the 'adds objects to it' phase), when MEDIA_REQUEST_IOC_QUEUE is called the request is validated (req_validate op), then queued (the req_queue op). When done with an object it can either be unbound from the request (e.g. when the driver has finished with a vb2 buffer) or marked as completed (e.g. for controls associated with a buffer). When all objects in the request are completed (or unbound), then the request fd will signal an exception (poll).

Define the public request API. This adds the new MEDIA_IOC_REQUEST_ALLOC ioctl to allocate a request and two ioctls that operate on a request in order to queue the contents of the request to the driver and to re-initialize the request.

A new helper function was introduced to facilitate the calculation of time per frame value whenever we have access to the full v4l2_dv_timings structure. This should be used only for receivers and only when there is enough accuracy in the measured pixel clock value as well as in the horizontal/vertical values.

Add a new flag to UAPI for DV timings which, whenever set, indicates that hardware can detect the difference between regular FPS and 1000/1001 FPS. This is specific to HDMI receivers.

pm_runtime_get_if_in_use() returns -EINVAL if runtime PM is disabled. This should not be considered an error. Generally the driver has enabled runtime PM already so getting this error due to runtime PM being disabled will not happen. Instead of checking for lesser or equal to zero, check for zero only. Address this for drivers where this pattern exists. This patch has been produced using the following command: $ git grep -l pm_runtime_get_if_in_use -- drivers/media/i2c/ | \ xargs perl -i -pe 's/(pm_runtime_get_if_in_use\(.*\)) \<\= 0/!$1/' Signed-off-by: Sakari Ailus <sakari.ailus@linux.intel.com> Reviewed-by: Tomasz Figa <tfiga@chromium.org> Signed-off-by: Mauro Carvalho Chehab <mchehab+samsung@kernel.org>

Replace the calls to pm_runtime_get_noresume() and pm_runtime_put() with pm_runtime_idle() in the driver's probe function.

Add support for 4:2:2, 4:4:4 and RGB 24/32 bits formats. This makes it a lot more useful, esp. as a simple video compression codec for use with v4l2-ctl/qvidcap. Note that it does not do any conversion between e.g. 4:2:2 and 4:2:0 or RGB and YUV: it still just compresses planes be they Y/U/V or R/G/B.

Merge tag 'libnvdimm-for-4.19_dax-memory-failure' of gitolite.kernel.org:pub/scm/linux/kernel/git/nvdimm/nvdimm Pull libnvdimm memory-failure update from Dave Jiang: "As it stands, memory_failure() gets thoroughly confused by dev_pagemap backed mappings. The recovery code has specific enabling for several possible page states and needs new enabling to handle poison in dax mappings. In order to support reliable reverse mapping of user space addresses: 1/ Add new locking in the memory_failure() rmap path to prevent races that would typically be handled by the page lock. 2/ Since dev_pagemap pages are hidden from the page allocator and the "compound page" accounting machinery, add a mechanism to determine the size of the mapping that encompasses a given poisoned pfn. 3/ Given pmem errors can be repaired, change the speculatively accessed poison protection, mce_unmap_kpfn(), to be reversible and otherwise allow ongoing access from the kernel. A side effect of this enabling is that MADV_HWPOISON becomes usable for dax mappings, however the primary motivation is to allow the system to survive userspace consumption of hardware-poison via dax. Specifically the current behavior is: mce: Uncorrected hardware memory error in user-access at af34214200 {1}[Hardware Error]: It has been corrected by h/w and requires no further action mce: [Hardware Error]: Machine check events logged {1}[Hardware Error]: event severity: corrected Memory failure: 0xaf34214: reserved kernel page still referenced by 1 users [..] Memory failure: 0xaf34214: recovery action for reserved kernel page: Failed mce: Memory error not recovered <reboot> ...and with these changes: Injecting memory failure for pfn 0x20cb00 at process virtual address 0x7f763dd00000 Memory failure: 0x20cb00: Killing dax-pmd:5421 due to hardware memory corruption Memory failure: 0x20cb00: recovery action for dax page: Recovered Given all the cross dependencies I propose taking this through nvdimm.git with acks from Naoya, x86/core, x86/RAS, and of course dax folks" * tag 'libnvdimm-for-4.19_dax-memory-failure' of gitolite.kernel.org:pub/scm/linux/kernel/git/nvdimm/nvdimm: libnvdimm, pmem: Restore page attributes when clearing errors x86/memory_failure: Introduce {set, clear}_mce_nospec() x86/mm/pat: Prepare {reserve, free}_memtype() for "decoy" addresses mm, memory_failure: Teach memory_failure() about dev_pagemap pages filesystem-dax: Introduce dax_lock_mapping_entry() mm, memory_failure: Collect mapping size in collect_procs() mm, madvise_inject_error: Let memory_failure() optionally take a page reference mm, dev_pagemap: Do not clear ->mapping on final put mm, madvise_inject_error: Disable MADV_SOFT_OFFLINE for ZONE_DEVICE pages filesystem-dax: Set page->index device-dax: Set page->index device-dax: Enable page_mapping() device-dax: Convert to vmf_insert_mixed and vm_fault_t
