headers: Remove some left-over license text in include/uapi/linux/dvb/ Remove some left-over from commit e2be04c7f995 ("License cleanup: add SPDX license identifier to uapi header files with a license") When the SPDX-License-Identifier tag has been added, the corresponding license text has not been removed. Remove it now. Signed-off-by: Christophe JAILLET <christophe.jaillet@wanadoo.fr> Signed-off-by: Hans Verkuil <hverkuil-cisco@xs4all.nl>

media: dvb: add continuity error indicators for memory mapped buffers While userspace can detect discontinuity errors, it is useful to also let Kernelspace reporting discontinuity, as it can help to identify if the data loss happened either at Kernel or userspace side. Update documentation accordingly. Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>

media: dvb-core: get rid of mmap reserved field The "reserved" field was a way, used at V4L2 API, to add new data to existing structs without breaking userspace. However, there are now clever ways of doing that, without needing to add an uneeded overhead. So, get rid of them. Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>

media: videobuf2: Add new uAPI for DVB streaming I/O Adds a new uAPI for DVB to use streaming I/O which is implemented based on videobuf2, using those new ioctls: - DMX_REQBUFS: Request kernel to allocate buffers which count and size are dedicated by user. - DMX_QUERYBUF: Get the buffer information like a memory offset which will mmap() and be shared with user-space. - DMX_EXPBUF: Just for testing whether buffer-exporting success or not. - DMX_QBUF: Pass the buffer to kernel-space. - DMX_DQBUF: Get back the buffer which may contain TS data. Originally developed by: Junghak Sung <jh1009.sung@samsung.com>, as seen at: https://patchwork.linuxtv.org/patch/31613/ https://patchwork.kernel.org/patch/7334301/ The original patch was written before merging VB2-core functionalities upstream. When such series was added, several adjustments were made, fixing some issues with V4L2, causing the original patch to be non-trivially rebased. After rebased, a few bugs in the patch were fixed. The patch was also enhanced it and polling functionality got added. The main changes over the original patch are: dvb_vb2_fill_buffer(): - Set the size of the outgoing buffer after while loop using vb2_set_plane_payload; - Added NULL check for source buffer as per normal convention of demux driver, this is called twice, first time with valid buffer second time with NULL pointer, if its not handled, it will result in crash - Restricted spinlock for only list_* operations dvb_vb2_init(): - Restricted q->io_modes to only VB2_MMAP as its the only supported mode dvb_vb2_release(): - Replaced the && in if condiion with &, because otherwise it was always getting satisfied. dvb_vb2_stream_off(): - Added list_del code for enqueud buffers upon stream off dvb_vb2_poll(): - Added this new function in order to support polling dvb_demux_poll() and dvb_dvr_poll() - dvb_vb2_poll() is now called from these functions - Ported this patch and latest videobuf2 to lower kernel versions and tested auto scan.

License cleanup: add SPDX license identifier to uapi header files with a license Many user space API headers have licensing information, which is either incomplete, badly formatted or just a shorthand for referring to the license under which the file is supposed to be. This makes it hard for compliance tools to determine the correct license. Update these files with an SPDX license identifier. The identifier was chosen based on the license information in the file. GPL/LGPL licensed headers get the matching GPL/LGPL SPDX license identifier with the added 'WITH Linux-syscall-note' exception, which is the officially assigned exception identifier for the kernel syscall exception: NOTE! This copyright does *not* cover user programs that use kernel services by normal system calls - this is merely considered normal use of the kernel, and does *not* fall under the heading of "derived work". This exception makes it possible to include GPL headers into non GPL code, without confusing license compliance tools. Headers which have either explicit dual licensing or are just licensed under a non GPL license are updated with the corresponding SPDX identifier and the GPLv2 with syscall exception identifier. The format is: ((GPL-2.0 WITH Linux-syscall-note) OR SPDX-ID-OF-OTHER-LICENSE) SPDX license identifiers are a legally binding shorthand, which can be used instead of the full boiler plate text. The update does not remove existing license information as this has to be done on a case by case basis and the copyright holders might have to be consulted. This will happen in a separate step. This patch is based on work done by Thomas Gleixner and Kate Stewart and Philippe Ombredanne. See the previous patch in this series for the methodology of how this patch was researched.

[media] demux.h: Remove duplicated enum "enum dmx_ts_pes" and "typedef enum dmx_pes_type_t" are just the same enum declared twice, since Kernel (2.6.12). There's no reason to duplicate it there, and sparse complains about that: drivers/media/dvb-core/dmxdev.c:600:55: warning: mixing different enum types So, remove the internal define, keeping just the external one. Internally, use only "enum dmx_ts_pes", as it is too late to drop dmx_pes_type_t from the userspace API. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
