Re: Buster & Kodi

The 17.6 version is actually the wrong version (not optimized for Raspberry Pi), you need the versions in archive.raspberrypi.org like 2:18.2-1~stretch. For pointers on how to run the stretch version under buster see: https://superuser.com/questions/1454950/raspberry-pi-kodi-wont-start-after-upgradi...

Re: Kodi installation on Raspbian Buster

You can run the stretch version (2:18.2-1~stretch) on buster by downgrading libcurl4 to libcurl3. Just change all "buster" references in /etc/apt/sources.list and /etc/apt/sources.list.d/* to stretch; make sure the archive .raspberrypi.org is in there, since that has the version that is optimized fo...

Re: Wrong SD card IO scheduler

Both SD-cards and SSD-drives perform best with the NOOP scheduler. I take care of this by creating /etc/udev/rules.d/60-mmc-scheduler.rules : # set noop scheduler for non-rotating disks ACTION=="add|change", KERNEL=="sd[a-z]", ATTR{queue/rotational}=="0", ATTR{queue/scheduler}="noop" # set noop sche...

Re: [Guide] Kodi on Raspbian Stretch

Small improvement on initial post, for those who are running kodi from a newly initialized chroot/schroot environment: There is also a dependency on libraspberrypi0; on most raspberry pi's this is already there, but to make this manual 110%, please add this package to the apt-get install line in the...

Re: Kodi on Raspbian Stretch

SOLVED kodi 2:17.4-1~stretch segfaulting after upgrading raspbian jessie to stretch: Turns out a normal upgrade+dist-upgrade leaves A LOT of old packages installed. The problem on my system was solved by doing: aptitude purge libnettle4 libhogweed2 libgnutls-deb0-28 , where I chose the following sol...

Re: Kodi on Raspbian Stretch

Upgraded from Jessie to Stretch, the kodi 2:17.3-1~jessie package was withheld, all worked fine. After an apt-get dist-upgrade it upgraded to kodi 2:17.4-1~stretch, I now get a segfault when starting kodi. I added start_x=1 to my /boot/config.txt ; did not help. I ran raspi-config to make sure the o...

Thanks for correcting that, I'm not an expert on sysbench...

It makes Eben even more right, I guess :-)

Re: Repository pool

I tried downgrading from raspbian stretch to raspbian jessie via Pinning, but found this was not working.

Am I right in that the raspbian pool is cleaned of old versions of packages, which causes downgrading this way not to work? Or is there something else going wrong in my downgrading process?

Re: 64bit vs 32bit benchmark. Eben was right

My conclusions were: 1) Floating point operations are up to 12 times faster in 64bits (see sysbench tests); 2) Binary size (on disk) increased with app. 22%, 3) memory usage can vary (in these tests) from no increase (memtester) to 4 times as much memory usage (valgrind test) in a 64 bits environmen...

Re: 64bit vs 32bit benchmark. Eben was right

In december 2016 I did some benchmarking, because I was convinced that 64bits would bring a lot more speed enhancements then people suspected; I had this experience on moving from i386 to x86_64, especially with FFDECSA, which is used for the decryption of media streams. It turned out then that not ...

Hi all, First of all big thanks to all Raspbian maintainers who provide such a beautiful OS for us all!

Re: Can we control the on-board leds

This is not really taking control from userspace, since the kernel has to be recompiled also (first reason to recompile is to enable sms95xx support as a module, since per default in Raspbian it is compiled in the kernel itself; second reason to recompile is for the module to include the patch... ) ...

Re: Can we control the on-board leds

I succesfully managed to clear the bright colored LED's on my Raspberry Pi, except for the red power led. Clearing or setting the green led is already documented, so I won't cover that here. Clearing the led's that are flickering at ethernet access can be done by modifying a few lines of kernel code...
