2020-10-01media: vidtv: simplify parameters for vidtv_pes_write_stuffing()Mauro Carvalho Chehab

2020-10-01media: vidtv: cleanup SDT string identifiersMauro Carvalho Chehab
In order to better test userspace applications, add an encoding for the strings. The original channel string is also too big. As we're just playing the first compasses of the 5th Beethoven Symphony, change the service name to just "Beethoven". Also, add a provider's name. For such purpose, let's point it to the Linux media community website. With such changes, the SDT table now looks more like one got from a real digital TV channel: SDT | table_id 0x42 | section_length 44 | one 2 | zero 1 | syntax 1 | transport_stream_id 1860 | current_next 1 | version 0 | one2 3 | section_number 0 | last_section_number 0 | network_id 65281 | reserved 255 |\ |- service 0x0880 | EIT schedule 0 | EIT present following 0 | free CA mode 0 | running status 4 | descriptor length 27 | 0x48: service_descriptor | service type 1 | provider 'LinuxTV.org' | name 'Beethoven' |_ 1 services Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org>
2020-10-01media: vidtv: cleanup PSI version numbersMauro Carvalho Chehab
There's no reason to use static vars to store PSI version numbers. Also, currently, version numbers are starting with 0x01, because there's a code being called that increases it to 1 for all table initializer code, as the code may support dynamic changes at the PS tables on some future. So, let's just initialize them to 0x1f, in order for the versions to be reported as starting from 0. Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org>
2020-10-01media: vidtv: fix initialization of the network_id field at SDTMauro Carvalho Chehab

For now, let's use the temporary private one. Once the Network Information Table (NIT) gets added, this should be reviewed. Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org>

The signal RKISP1_CIF_ISP_FRAME is set when the ISP completes outputting the frame to the next block in the pipeline. In order to keep buffer synchronization we assume that the RKISP1_CIF_ISP_V_START signal never arrives together with the RKISP1_CIF_ISP_FRAME signal. In case those signals arrive together then the code is not able to tell if the RKISP1_CIF_ISP_FRAME signal relates to the frame of the current v-start or the previous.

2020-09-27media: staging: rkisp1: params: avoid using buffer if params is not streamingDafna Hirschfeld
Currently, the first buffer queued in the params node is returned immediately to userspace and a copy of it is saved in the field 'cur_params'. The copy is later used for the first configuration when the stream is initiated by one of selfpath/mainpath capture nodes. There are 3 problems with this implementation: - The first params buffer is applied and returned to userspace even if userspace never calls to streamon on the params node. - If the first params buffer is queued after the stream started on the params node then it will return to userspace but will never be used. - The frame_sequence of the first buffer is set to -1 if the main/selfpath did not start streaming. A correct implementation is to apply the first params buffer when stream is started from mainpath/selfpath and only if params is also streaming. The patch adds a new function 'rkisp1_params_apply_params_cfg' which takes a buffer from the buffers queue, apply it and returns it to userspace. The function is called from the irq handler and when main/selfpath stream starts - in the function 'rkisp1_params_config_parameter' Also remove the fields 'cur_params', 'is_first_params' which are no more needed.

2020-09-27media: rc: gpio-ir-recv: add QoS support for cpuidle systemJoakim Zhang
GPIO IR receive is much rely on interrupt response, uneven interrupt latency will lead to incorrect timing, so the decoder fails to decode it. The issue is particularly acute on some systems which support cpuidle, not all, dynamically disable and enable cpuidle can solve this problem to a great extent. However, there is a downside to this approach, the measurement of header on the first frame may incorrect. Test on i.MX8M serials, when enable cpuidle, interrupt latency could be about 500us. With this patch: 1. has no side effect on non-cpuidle system, even runtime pm api won't be invoked to avoid a bunch of pm busy work for devices that do not need it, including spinlocks, ktime, etc. 2. latency is still much longer for the first gpio interrupt on cpuidle system, so the first frame may not be decoded. Generally, RC would transmit multiple frames at once press, we can sacrifice the first frame. 3. add "linux,autosuspend-period" property in device tree if you also suffer this cpuidle issue.
