18:12.49DocScrutinizer05Pali: fix welcome screen to allow closing it by hw button press or ctrl-Q?
18:13.08PaliDocScrutinizer05: it is closed :-(
18:13.17DocScrutinizer05sheeet
18:13.19Paliand written in C++ (instead C)
18:13.22Paliso hard to RE
18:13.25Palimaybe impossible
18:13.26DocScrutinizer05ohmy
18:13.41Palione piece of C++ program in Maemo...
18:13.43DocScrutinizer05wrap into a wrapper which you could kill off?
18:14.19DocScrutinizer05http://campmap.mazdermind.de/
18:14.23DocScrutinizer05oops
18:14.40PaliI will wait... I believe somebody could know why SPI bus is broken
18:14.45Paliin 4.2-rc1 kernel
18:15.02DocScrutinizer05sure, but that shit welcome screen needs to die or get fixed anyway
18:15.36DocScrutinizer05maybe simply kill it after 90s
18:17.58DocScrutinizer05((why SPI bus is broken)) blame DT ;-)
18:19.02Palithis looks like some bug in spi code
18:19.06Palior maybe drivers...
18:19.27Paliand I see also problems with i2c bus and drivers
18:19.30Palitimeout errors
18:19.46Palitwl4030 parts probe failing...
18:20.06Palibut after few seconds at second/third attmpt, they are ok
18:20.09Paliand drivers loaded...
18:20.26PaliI believe it is just some funny race condition error
18:20.34*** join/#neo900 Zero_Chaos (~zerochaos@gentoo/developer/pentoo/zerochaos)
18:20.36DocScrutinizer05ouch
18:20.50DocScrutinizer05power sequencing?
18:21.12Paliproblem with linux kernel globally is that you cannot write driver dependency... (A depends on B, B depends on C, ...)
18:21.24DocScrutinizer05OUUUUUUCH
18:21.43Paliand if kernel init drivers in random order, just init functions check unment dependency and return -EPROBEDEFER
18:21.47Palior what
18:22.19Paliand after some time kernel try to call driver init function again
18:23.02Paliit is same as problem with isp1704 and bq2415x drivers... isp1704 send events to bq2415x about "charger attached"
18:23.20Paliso bq2415x in init code has check if isp driver is loaded and working
18:23.44DocScrutinizer05:nod:
18:23.48DocScrutinizer05hail DT
18:24.03Paliits not DT
18:24.09DocScrutinizer05exactly
18:24.10Palisame problem is with board code
18:24.22DocScrutinizer05since DT lacks any reasonable way to handle that
18:24.31Paliproblem is in kernel itself
18:24.41Paliwith device drivers API
18:24.49Palino way to define this situation
18:24.55DocScrutinizer05:nod:
18:25.03DocScrutinizer05my complaints since.... ages
18:25.26Palithis problem is also x86 systems
18:25.27DocScrutinizer05drivers need to be smart and platform specific
18:25.43DocScrutinizer05with DT they are not

22:24.46MonkeyofDoomby bunnie :)
22:32.45DocScrutinizer05Bunnie! :-D
22:32.50DocScrutinizer05thanks a lot!
23:01.14Oksanawonders if it is possible to attach an external mouse by the time of welcome screen, to use it instead of touchscreen? Likely not?
23:01.33DocScrutinizer05likely not
23:02.00DocScrutinizer05you'd need to enable hostmode
