Basically it is all coming from the removed hacks. It was 2084 LOC and now it is 1609 LOC - it is near 500 LOC less.

I have also Anysee, AU6610 and EC168 drivers converted, but those are far away complexity compared for AF9015, since not so interesting.Īll-in-all, code size goes down rather much. I selected Afatech AF9015 driver as it is one of the most complex and main motivator of whole DVB USB changes. I finally decided to publish one rather complex DVB USB driver as a demonstration what it looks like. are broken because driver/chip could support multiple DTV standard.need to be properties per delivery system.currently implemented as a properties per driver.those has been broken since MFE => SFE change.some drivers blocks IOCTL when taking measurement (bad).some drivers starts own internal work-queue for polling (complexity).typical cycle is : start measurement => wait => read counters.many static counters could not be read as a 'one go'.currently not supported => LNA is configured off typically.there is quite a lot of devices having LNA.LNA (low-noise amplifier) support for DVB API I already ran RFC but have been too busy for implementing it :].what are new parameters needed for DVB API?.

some core changes needed, like status (is locked etc).

new delivery system for frontend API called SDR?.

SDR is quite near what is digital TV streaming.

there is existing devices that are SDR (RTL2832U 'rtl-sdr').

SDR - Softaware Defined Radio support DVB API

own PM is still working very well, at least I dont know any problems.

study if it is wise to use Kernel services instead of own.

there seems to be Kernel services for power-management.

Use Kernel power management instead of own

quite a lot work to get it working in case of streaming is ongoing.

support is currently quite missing, all what is done is on interface drivers.

for example BER is not valid when demod is unlocked.

we can also check if call is possible to perform in given condition.

we can do almost all validly checking inside core.

values are highly hooked up to used television standard.

currently each driver needs to validate those.

General validly checking for demodulator callback input values Will try to implement what I can (and what I like most interesting.

Feel free toĬomment - what are not needed or what you would like to see instead. Here is my list of needed DVB core related changes. I ended-up listing known bugs, insufficientįunctionality and some new features and sent plan to the Linux-Media I will write article about thatĭVB core part recently. DVB USB changes are quite ready and I am going to sent

First one was DVB USB enhancements and second part was for DVBĬore issues. As you could remember I initially scheduled my GSoC project to two
