[Zaurus-devel] Event based zaurusd
Hello, now that we are running 2.6.38 kernels can we move to the new event based zaurusd [1]? Any particular drawback?

Re: [Zaurus-devel] Event based zaurusd
reading following lines from linux-arm-kernel [2] I wonder if we could have zaurusd as driver in kernel tree... ... Since this is a one-off kind of thing, a singleton driver that controls power, reset and some GPIO on the chip. I contemplate moving the stuff to either: drivers/misc/ux500/* include/linux/misc/ux500/* or: drivers/platform/arm/ux500/* include/linux/platform/arm/ux500/* Are any of these generally speaking good ideas? Or maybe drivers/arm? ...

Therefore, this structure is replaced by struct nand_ecclayout in linux kernel from the version 2.6.17. Consequently, the ioctl command changed from MEMGETOOBSEL to ECCGETLAYOUT I was using 2.6.26 kernel. Please report if that happens on other hardware too.

Re: [Zaurus-devel] Zaurus CF tests -- ok
Hi! After getting _good_ power supply, I was able to untar and rm ltp tree 100 times so far. 2.6.38, ext3. (So metan no, I do not see any weird ext3 problems). Hmm, I'm using original adapter, but who knows if it's okay to use... Another strange thing is... I see lots of duplicated keystrokes -- like type pavel but machine understands paavel. But it only seems to happen when I'm _not_ trying to debug it?! That seems to be side effect of machine under load (it has gpio keyboard). ( So... just because something needs 5V does not mean you should charge it from USB. Yes, I'm talking about zaurus. I noticed that it crashed rather quickly when connected to USB power. (For example in tar/rm test). So I took multimeter, and there was 4.15..4.5V on USB :-(. With power from USB extension cable, it crashes in 5 minutes. It seems to toggle charger a lot, as voltage on the cable is only 4.2..4.5V. I guess it is software problem in the charging code. ) The zaurus actually is AFAIK unable to run from battery when connected to the external power, so weak power line may explain some of the strange behaviour. -- metan ___ Zaurus-devel mailing list Zaurus-devel@lists.linuxtogo.org http://lists.linuxtogo.org/cgi-bin/mailman/listinfo/zaurus-devel
