Re: Fedora 21 REMIX for Raspbery Pi 2B

Thanks for including NAT in the kernel. This makes it possible to use the F21 REMIX for OpenVPN services.
(Standard Pidora does not include NAT)

Re: Fedora 21 REMIX for Raspbery Pi 2B

Ok. Findings so far. 1. Fedora seems to achieve about 60-70% of the performance of (some? most? all?) other distros. This was tested using the pystone benchmark version 1.1 on the following configurations (pystones/second numbers between parens): * Raspberry Pi model B, 512MB, distro's: Pidora 18, P...

Re: Fedora 21 REMIX for Raspbery Pi 2B

Can you give it a try on your hardware, with the standard raspbian (e.g. via NOOBS)?
If you get the same results it may be time to file an issue at Fedora.

Re: Fedora 21 REMIX for Raspbery Pi 2B

Indeed :(

With the new power supply, Raspbian (not overclocked):

Pystone(1.1) time for 50000 passes = 3.63

Re: Fedora 21 REMIX for Raspbery Pi 2B

It does, however, not explain why Raspbian gets the higher pystones with the same power supply that apparently is not enough for Fedora.

Re: Fedora 21 REMIX for Raspbery Pi 2B

I got it from http://svn.python.org/projects/python/t ... pystone.py .

However, I do not expect this a possible cause, since I use exactly this pystone script on all configurations.

Re: Fedora 21 REMIX for Raspbery Pi 2B

I'm running the unmodified F21 remix from the first post of this thread on RPi2. I'd expect anyone else running the same install on the same hardware to get the same results. And yes, I did update the kernel: Linux fidora-minimal-remix 3.18.9-504.20150311git5e3fb83.sc20.armv7hl.bcm2709 #1 SMP PREEMP...

Full speed ahead?

Installs and runs flawlessly, except for one thing: I cannot get the CPUs to run at maximum speed. It seems that the CPUs are locked to 600MHz. Switching to performance governor doesn't help.

How can I get the full speed?

Re: Minimal server

Interesting, please share.

I made some attempts to start from the other side: a minimal Fedora 20 system (about 700MB) but I got stuck trying to find out what RasPI components were required.
I wish we had a good RasPI emulator, since testing is tedious.

Re: Minimal server

The idea of removing packages to save a few MB of space is rather overkill. SD cards are relatively cheap and you just need to get one that is big enough for your needs, even with the packages present on the distribution. Just don't run them by whittling down what services are started at boot time....

Re: Minimal server

Yes, of course. In fact, Pidora 20 is already much better than Pidora 18 in that it starts much less daemons in multi-user mode.
However, I frequently need to copy the SD cards so having less files on the cards matters also.

Minimal server

I often use Pidora systems for small servers (DNS, DHCP, NTP, VPN, ...). For this it would be nice to have a real minimal Pidora system. E.g., no Gnome, no X, no desktop tools, no fancy applications. Has anyone ever tried to build such a system? Removing packages from the standard remix is very tedi...

Re: Installation stalls at time syncro

I ran into the same problem.
I restarted the install from scratch and disabled NTP synch. Everything went well.
Later I ran fastboot again (manually) to set the time/zone/ntp synching and it works since.

XBMC video with subtitles via JSON

Given a video file with external subtitles (.srt) file, how can I instruct XBMC via JSON to start playing this movie with this subtitles file? I can start playing the video but I cannot find how to associate the subtitles.

Thanks.
