When debugging issues that involve more than one video queue, messages related to multiple queues get interleaved without any easy way to tell which queue they relate to. Fix this by adding a queue name to vb2_queue, and printing it in all debug messages in the vb2 core and V4L2 layers. If the name isn't set by drivers, it is automatically filled with the queue direction and address.

2020-06-23media: videobuf2: add cache management membersSergey Senozhatsky1-0/+10
Extend vb2_buffer and vb2_queue structs with cache management members. V4L2 UAPI already contains two buffer flags which user-space, supposedly, can use to control buffer cache sync: - V4L2_BUF_FLAG_NO_CACHE_INVALIDATE - V4L2_BUF_FLAG_NO_CACHE_CLEAN None of these, however, do anything at the moment. This patch set is intended to change it. Since user-space cache management hints are supposed to be implemented on a per-buffer basis we need to extend vb2_buffer struct with two new members ->need_cache_sync_on_prepare and ->need_cache_sync_on_finish, which will store corresponding user-space hints. In order to preserve the existing behaviour, user-space cache managements flags will be handled only by those drivers that permit user-space cache hints. That's the purpose of vb2_queue ->allow_cache_hints member. Driver must set ->allow_cache_hints during queue initialisation to enable cache management hints mechanism.

2020-06-11media: videobuf2-dma-contig: fix bad kfree in vb2_dma_contig_clear_max_seg_sizeTomi Valkeinen1-1/+1
Commit 9495b7e92f716ab2bd6814fab5e97ab4a39adfdd ("driver core: platform: Initialize dma_parms for platform devices") in v5.7-rc5 causes vb2_dma_contig_clear_max_seg_size() to kfree memory that was not allocated by vb2_dma_contig_set_max_seg_size(). The assumption in vb2_dma_contig_set_max_seg_size() seems to be that dev->dma_parms is always NULL when the driver is probed, and the case where dev->dma_parms has bee initialized by someone else than the driver (by calling vb2_dma_contig_set_max_seg_size) will cause a failure. All the current users of these functions are platform devices, which now always have dma_parms set by the driver core. To fix the issue for v5.7, make vb2_dma_contig_set_max_seg_size() return an error if dma_parms is NULL to be on the safe side, and remove the kfree code from vb2_dma_contig_clear_max_seg_size(). For v5.8 we should remove the two functions and move the dma_set_max_seg_size() calls into the drivers.

2020-04-29media: cec-gpio: handle gpiod_get_value errors correctlyHans Verkuil1-9/+7
gpiod_get_value() can return negative values if an error occurs. In several places this error code was ignored. Ensure that errors codes are handled correctly throughout the CEC pin framework and CEC pin drivers. The return code of the cec_pin_ops read() callback had to be changed from 'bool' to 'int', which mean the prototype of that callback in the sun4i drm driver also had to be changed.

Building those list is a standard procedure described in section '8.2.4 Decoding process for reference picture lists construction' of the H264 specification. We already have 2 drivers needing the same logic (hantro and rkvdec) and I suspect we will soon have more. Let's provide generic helpers to create those lists.

v4l2_fh struct define differently by CONFIG_V4L2_MEM2MEM_DEV. If some vendors use CONFIG_V4L2_MEM2MEM_DEV by module, it can make the mismatch of v4l2_fh sturct. By the mismatch, the following error occurs. =============================== [ 7.533506] v4l2_mem2mem: disagrees about version of symbol video_devdata [ 7.533594] v4l2_mem2mem: Unknown symbol video_devdata (err -22) [ 7.535319] v4l2_mem2mem: disagrees about version of symbol v4l2_event_pending [ 7.542532] v4l2_mem2mem: Unknown symbol v4l2_event_pending (err -22) =============================== So v4l2_fh struct is modified to does not have dependency for CONFIG_V4L2_MEM2MEM_DEV.

2020-04-21media: rc: if kernel is built without an IR codec, don't advertise itSean Young1-27/+76
If the kernel is built without e.g. the imon IR decoder, the protocols sysfs file still show the protocol as available. If user-space tries to enable this decoder, the kernel will report an error: $ echo +imon > /sys/class/rc/rc0/protocols [ 57.693033] rc_core: Loaded IR protocol module ir-imon-decoder, but protocol imon still not available Ensuring that unavailable protocols are not advertised, ensures that users space knows it is not available, and a BPF based IR decoder can be loaded instead. This supports the case when no kernel-based codec needs to be compiled in, and every IR decoder can be BPF based.

2020-04-14media: add v4l2 JPEG helpersPhilipp Zabel1-0/+135
Add helpers for JPEG header parsing. They allow both scanning for marker segment positions and later parsing the segments individually, as required by s5p-jpeg, as well as parsing all headers in one go, as required by coda-vpu. The frame header is always parsed, as basically all decoders are interested in width, height, and number of components. For convenience, the JPEG chroma subsampling factors are decoded into a v4l2_jpeg_chroma_subsampling enum. Only baseline and extended sequential DCT encoded JPEGs with 8-bit or 12-bit precision with up to four components are supported.
