#1. I see two packages but don't know what the difference is between the community and alarm repos and did not see anything about it on the Arch wiki

$this->bbcode_second_pass_code('', 'community/kodi 14.1-2
A software media player and entertainment hub for digital media
alarm/kodi-rbp 14.1-4
A software media player and entertainment hub for digital media for the Raspberry Pi')
#2. I don't know which libgl is optimized for the RPi2.
$this->bbcode_second_pass_code('', ':: There are 5 providers available for libgl:
:: Repository extra
1) mesa-libgl
:: Repository alarm
2) gpu-viv-bin-mx6q-dfb 3) gpu-viv-bin-mx6q-fb 4) gpu-viv-bin-mx6q-wl 5) gpu-viv-bin-mx6q-x11')
Thank you in advance.
