02:41 cbxbiker61 i just received my hummingboard i2ex, it's a sweet piece of kit
02:42 cbxbiker61 now i just need to figure out why it's resetting about the time I get xbmc loaded (i used a card working in a cubox-i4)
12:04 joost_dtn okay, which linux image should i use to get decent, proper working bluetooth connectivity for my cubox-i2ultra
12:06 joost_dtn the closest thing to get it working was on geexbox, which was my original goal to begin with to get it working with that
12:07 joost_dtn figured that i might just as well try on a regular distribution
12:08 joost_dtn the current jessie image doesn't even have a proper kernel that has bluetooth enabled it seems
12:10 joost_dtn been searching on the geexbox forums, the cubox forums and even plain debian forums and tried every suggestion, but it all fails
12:10 joost_dtn on the geexbox image i do get to see the bluez controller, am able to power it up, but scans do not show up anything, not using hcitool or bluetoothctl

13:13 cbxbiker61 i've just been doing a bit of experimentation with ffmpeg/x265
13:14 cbxbiker61 found out that my couple of year old quad core notebook is fast enough to decode, which is a good thing
13:15 cbxbiker61 a quick look at cpu utilization on my amd 5350 showed the cores running at about 60%, so i don't think the quad cubox-i is going to be quite enough
13:16 cbxbiker61 i also think most of the assembler optimations in x265 are for x86
13:19 cbxbiker61 wasn't too long ago the x265 guys were saying "desktop" level machine, nice to see the progress to running fine on a notebook
13:20 bencoh x265 running fine ?
13:20 bencoh well I guess you're not talking about live encoding :)
13:20 cbxbiker61 it looks good to me
13:21 bencoh (decoding in ffmpeg isnt done by x265 btw)
13:22 cbxbiker61 i've got dueling ffmpeg's running right now, so all i can say is that even though half of the cpu is soaked up by another process, i'm doing about 20fps encoding on an 4.7GHz 8 core
13:23 cbxbiker61 720p @ crf 24
13:23 bencoh yeah, not ready for live ;)
13:23 cbxbiker61 tell ya what...
13:24 cbxbiker61 they've been working on opencl support, but haven't released the code yet
13:25 cbxbiker61 at least the h265 spec was written with parallel processing in mind
13:27 cbxbiker61 if opencl with a good card could boost that 3-4 times, we'd be in relatively good shape
13:30 joost_dtn just tried archlinux using the wiki instructions, on linux 3.10 kernel, with the firmware installed: no dice.
13:30 joost_dtn starting to suspect bluetooth hardware failure
14:56 joost_dtn okay. may it be forever noted that for bluetooth to work on a Cubox i2ultra, you need to make sure that brcm_patchram_plus needs to be invoked WITHOUT --enable_lpm
15:00 joost_dtn One parameter '--enable_lpm' would send a 'hci_sleep_cmd' to Bluetooth chip, which means that Bluetooth chip may 'sleep' at some time after that command has been sent. So, I tried to remove it from the command, and bluetooth works well afterwards.
15:19 balrog joost_dtn: is the chip sleeping and not waking up?
15:20 joost_dtn apparently
15:20 joost_dtn tried all major distro's and images, all had the same trouble
15:21 joost_dtn found out in some unrelated github project about that --enable_lpm switch
15:21 joost_dtn removed it from geexbox' start-brcm-patcram-plus script and it worked instantly
20:08 msalerno Archlinux - Has anyone gotten bluetooth working?
