Re: Next firmware tree is now 3.10

Was there any resolution to the loss of FSTRIM in recent kernels? I've just updated to #614 from #577, and now my fstrim cron job is failing with the new kernel.

If fstrim serves no purpose on an SD card then fine, I'll stop running it, is everyone now agreed it is of no value?

fstrim is useless on sdcards, as dummy controllers in sdcards don't support trim command anyway.

Minor update, I could not find a binary "bc" but the source kit loaded and built running code with warnings. I used:

Code: Select all

mkdir /usr/src/bc/
cd /usr/src/bc/
cat /etc/apt/source.list
#
deb-src http://ftp.us.debian.org/debian stable main contrib non-free rpi
#
apt-get source bc
./configure
. . . 
make
. . . 
make install
I am a little surprised by the Debian comment . . . "bc" eliminated a 'perl' utility . . . yet introduced a whole new 'language.' Regardless, the build is working.

Hello,

Not sure if this is the right place to mention, but I suspect gpio_pcf857x is broken in 3.10.36/37:

I tried to recompile 3.10.36 with usb driver as a module and it fails like this

Code: Select all

  Kernel: arch/arm/boot/zImage is ready
  Building modules, stage 2.
  MODPOST 1226 modules
ERROR: "DWC_TASK_HI_SCHEDULE" [drivers/usb/host/dwc_otg/dwc_otg.ko] undefined!
ERROR: "fiq_fix_enable" [drivers/usb/host/dwc_otg/dwc_otg.ko] undefined!
make[1]: *** [__modpost] Error 1
I admit it is not very practical to have it as module, I just tried to experiment with power consumption of model B. It did save significant power when not enabled in kernel but otherwise it brings more questions than answers :-) More details in this thread
