i open this thread to provide infos and get reports about new OpenELEC testbuilds.

to update a older build without reinstalling: http://wiki.openelec.tv/index.php?title ... g_OpenELEC
I have created a new build to test a more actual kernel based on bootc's work. He wants to get reports how well this kernel works for the "masses", what are the problems and if it runs stable. This kernel is based on the active developed kernel "linux-3.2.18".
After some tests here with this kernel i have noticed this kernel provides us a much better data transferrate from SDcards. for example:
- Kernel 3.1.10 (original):
Code: Select all
root ~ # sync; rm testing; sync; time ( dd if=/dev/zero of=testing bs=16k count=10000; sync) 10000+0 records in 10000+0 records out 163840000 bytes (156.3MB) copied, 38.149376 seconds, 4.1MB/s real 0m39.139s user 0m0.060s sys 0m3.420s
- Kernel 3.2.18 (new):
as you see, writing on the SDcard is around 2 times faster (at least here for me).
Code: Select all
root ~ # sync; rm testing; sync; time ( dd if=/dev/zero of=testing bs=16k count=10000; sync) 10000+0 records in 10000+0 records out 163840000 bytes (156.3MB) copied, 21.412055 seconds, 7.3MB/s real 0m23.431s user 0m0.060s sys 0m3.440s
Code: Select all
dmesg
- End of kernel start:
Kernel 3.1.10:Kernel 3.2.18:Code: Select all
[ 2.913671] Freeing init memory: 3728K
(this means (here) the kernel starts in 1s sec instead 3 sec.)Code: Select all
[ 1.095703] Freeing init memory: 3740K
- or starting of service "udev"
Kernel 3.1.10:Kernel 3.2.18:Code: Select all
>[ 6.948481] udevd[717]: starting version 184
(another 3.3 sec improvenment here)Code: Select all
>[ 3.620709] udevd[736]: starting version 184
- or beginning to start XBMC:
Kernel 3.1.10:Kernel 3.2.18:Code: Select all
[ 9.901918] Console: switching to colour dummy device 80x30
(what i should say?)Code: Select all
[ 6.121219] Console: switching to colour dummy device 80x30
- The wrong thumbnail colors should be fixed
- there are much changes in in the XBMC which needs to resetup your audio hardware, it is important to remove your "guisettings.xml" before if you upgrade from a earlyer build, reboot and resetup your audio device:
Code: Select all
rm -rf /storage/.xbmc/userdata/guisettings.xml
- i have tried a WLAN stick with this build based on the "r8712u" wlan driver which work very well here (but is not fast enough to stream 1080p movies over samba)
- mounting external USB drives works here too
let me know how it works for you
