2020-10-01media: vidtv: cleanup SDT string identifiersMauro Carvalho Chehab1-2/+5
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 Chehab1-6/+3
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>

2020-09-27media: rc: gpio-ir-recv: add QoS support for cpuidle systemJoakim Zhang1-0/+53
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.

pm_runtime_get_sync() increments the runtime PM usage counter even when it returns an error code, causing incorrect ref count if pm_runtime_put_noidle() is not called in error handling paths. Thus call pm_runtime_put_noidle() if pm_runtime_get_sync() fails.

pm_runtime_get_sync() increments the runtime PM usage counter even when it returns an error code, causing incorrect ref count if pm_runtime_put_noidle() is not called in error handling paths. And also, when the call of function vpe_runtime_get() failed, we won't call vpe_runtime_put(). Thus call pm_runtime_put_noidle() if pm_runtime_get_sync() fails inside vpe_runtime_get().
