| 00:31.01 | CubieFAQ | vga-lvds-tv: VGA/LVDS/TV outputs are available on the 2mm headers. To make use of them you need to add the resistors/buffers and connector required by the interface you want to use. Cubieboard only supports two displays at the same time and some pins are shared between VGA/LVDS/TV. You have to provide the interface hardware *and* properly configure the pins to which it is attached. |

| 11:36.37 | mnemoc | then we can write a driver |

| 21:31.48 | mur_ | - 1 USB 2.0 port *or* a standard LAN port |
| 21:31.49 | mnemoc | mur_: this channel is about the cubieboard, and by extension about it's SoC. |
| 21:31.57 | mur_ | - 2GB of RAM on SoC |
| 21:32.22 | mur_ | yeah it's fine, can be a tiny SoC board, doesn't have to be a stick. |
| 21:33.13 | mur_ | so back to my original question then, does anyone knows if a cubieboard with 2GB RAM and a more punchy CPU are in the works? |
| 21:33.33 | mnemoc | mur_: i answered you |
| 21:33.35 | mur_ | beacuse at least cubieboard has integrated LAN & and a SATA port. |
| 21:34.01 | mnemoc | for other SoCs there are other boards |
| 21:34.08 | mur_ | so just cause they "discourage" it means no one's gonna try it? |
| 21:34.46 | FergusL | I don't know of an android stick with quad core |
| 21:34.53 | FergusL | well there is the very new |
| 21:34.57 | FergusL | Zelz or someting |
| 21:34.59 | mur_ | FergusL, thanks. |
| 21:35.19 | FergusL | but I'm looking at MK808 (1.6Ghz quad, ubuntu compatible with picuntu) |
| 21:35.21 | FergusL | 1Gb ram |
| 21:35.56 | mur_ | I've been at it for days, all the sticks you find on the market are Rockchip RK3066, however they released RK3188 few weeks ago but nothing. |
| 21:36.08 | mur_ | RK3188 is quad core A9. |
| 21:36.19 | FergusL | yes |
| 21:36.27 | FergusL | are you looking for Linux support ? |
| 21:37.00 | mur_ | SATA port on a stick is a "no-no" so then I require 2 USB ports, one for FE100M/GE and one for external storage HDD. |
| 21:37.09 | mur_ | yeah, definitely need Debian. |
| 21:37.22 | mnemoc | again, this is off-topic. there are other channels for that |
| 21:37.25 | mur_ | these sticks/SoC will be hosted in a datacenter. |
| 21:37.31 | mur_ | mnemoc, we heard you once. |
| 21:38.21 | FergusL | is it too far off ? |
| 21:38.48 | mur_ | FergusL, don't mind the guy, probably a rampant troll who's on "that" specific period of the month. |
| 21:38.50 | FergusL | maybe that's the start of something, and made possible by this channel, maybe this conversation could attract new people ! |
| 21:39.12 | mur_ | communists, you know.. |
| 21:39.41 | mnemoc | no, channel owner |
| 21:40.04 | mur_ | so, if you're the channel "owner", does that mean you "own" us all and our right of free speech? |
| 21:40.50 | mur_ | no wonder why there are 106 lusers and no one is actually "talking". |
| 21:40.58 | RaYmAn | seriously? free speech argument? |
| 21:41.07 | mur_ | yeah, seriously. |

| 21:41.51 | RaYmAn | by your argument, I'm being supressed if I can't go up to $random building and spraypaint my personal message, without fear of prosecution. |
| 21:41.57 | RaYmAn | free speech!!!! |
| 21:42.21 | mur_ | I asked if there was a 2.0 version coming of the cubieboard with a beefier CPU planned or not. |
| 21:42.31 | RaYmAn | but yes, this is freenode. You are *free* to start your own channel and discuss whatever you want :) |
| 21:42.37 | RaYmAn | Did you not get an answer? :) |

| 21:50.01 | Dave77 | is it possible to change the overscan area in ubuntu/linaro? what is the configuration app cmd line or config file I need to edit? |
| 21:50.37 | mnemoc | FergusL: no, didn't have the pleasure |
| 21:50.56 | FergusL | "<mur_> fucking islamic communist garbage motherfucks are everywhere these days." that line was great |
| 21:50.57 | mnemoc | RaYmAn: but the first time I see one on these channels |
| 21:51.13 | mnemoc | FergusL: rotfl :D |
| 21:51.38 | FergusL | that being said, I don't think we were that far off, I only agree about his behaviour |
| 21:52.12 | mnemoc | Dave77: last time you asked Turl told you to disable it in your TV... |
| 21:53.36 | RaYmAn | mnemoc: I suspect a lot of those overscan questions come from the fact that rpi lets you change overscan.. tbh, I'm rather surprised there's even an overscan issue on hdmi when using standard resolutions |
| 21:53.50 | Dave77 | I'm using PC monitor, no such options, that can only be configured using a service mode probably, I can adjust overscan on my CRT in service mode.. but no DVI/HDMI |
| 21:53.54 | RaYmAn | (though, the i.mx6q stick I have, actually has overscan controls in android as well) |
| 21:54.26 | mnemoc | i see |
| 21:54.45 | FergusL | OFF TOPIC, insult us and leave |
| 21:54.53 | mnemoc | FergusL: :) |
| 21:56.24 | Dave77 | on my monitor it says 720p - linaro image.. booted android and it seems ok (usable) apart from purple screen |
| 21:56.33 | FergusL | (there's also the wandboard btw) |
| 21:57.24 | mnemoc | FergusL: imo, it's very different when someone already here and interested by the $topic asks about not-too-far topics than when someone comes just to ask about those things with a clear attitude problem |
| 21:57.38 | FergusL | yes, that's the point |

| 23:37.01 | mnemoc | lawrence mentioned the A20 is already out, so it might be possible to get some A20-based 2012-09-09 boards... not sure about core code availability |
| 23:37.42 | mnemoc | damn CNY |
| 23:37.44 | Gumboot | I'd be quite interested in that. |
| 23:37.49 | mnemoc | me too |
| 23:37.57 | Gumboot | NEON performance should be good. |
| 23:37.59 | mnemoc | far more than a A31-based board |
| 23:38.11 | pidpawel | hmm. i used cubieboard.fex (not cubieboard512) and set in menuconfig 896MB, but once booted i see about 40MB of ram. what am i missing? |
| 23:38.11 | mnemoc | interest I mean |
| 23:38.42 | mnemoc | pidpawel: the head of your dmesg will show what reserves tou have active |
| 23:38.46 | Gumboot | Twice as many cores and twice the pipeline width on each core (for NEON). If you have a lot of compute to do it should be very impressive for its size. |
| 23:39.22 | ssvb | Gumboot: twice the pipeline width on each core? |
| 23:39.34 | Gumboot | For NEON. |
| 23:39.39 | Gumboot | Might have to double-check that. |
| 23:40.32 | Gumboot | Definitely true for A15, and I think A7 followed suite. Maybe just so the performance profile wasn't too far out of place for the big.LITTLE arrangement. |
| 23:40.51 | Gumboot | Or maybe it's a configuration option. |
| 23:42.27 | ssvb | Gumboot: I would be very happy if A7 had roughly the same NEON performance as A8 per cycle, but this does not seem to be likely |
| 23:42.51 | pidpawel | [ 0.000000] Memory: 448MB = 448MB total |
| 23:42.51 | pidpawel | [ 0.000000] Memory: 314584k/314584k available, 144168k reserved, 0K highmem |
| 23:42.51 | pidpawel | mnemoc |
| 23:42.52 | ssvb | Gumboot: after all, the NEON unit in A8 is better than A9 |
| 23:44.01 | mnemoc | pidpawel: paste from there everything up to the begining... in a paste service. e.g. http://dpaste.com |
| 23:44.11 | Gumboot | I don't think A9 is worse. I think it just needs different tuning. |
| 23:44.20 | mnemoc | ssvb: so you expect 2xA7 to be worse than A8? |
| 23:44.50 | ssvb | mnemoc: I expect 1xA7 to be worse than A8 :) |
| 23:44.56 | Gumboot | Hm. Some random page says A7 NEON is 64-bit. I wonder if I can find a reference which disagrees. |
| 23:45.53 | ssvb | Gumboot: that's too vague, for example NEON unit is 64 bit for floating point and 128 bit for integer workload in both A8 and A9 |
| 23:46.43 | pidpawel | mnemoc: what are you looking for exactly? |
| 23:46.46 | Gumboot | Same reference put Krait down as 128bit. |
| 23:47.16 | ssvb | Gumboot: but of course anadtech has labelled A8/A9 as 64-bit, just to make them seem twice worse than qualcomm on paper :) |
| 23:47.21 | mnemoc | pidpawel: you said you had ~800MB of memory, that line tells you actually have 512 - reserves |
| 23:47.28 | mnemoc | pidpawel: so something is fishy |
| 23:47.30 | Gumboot | Well, it's _possible_ they know what they're talking about. |
| 23:47.52 | Gumboot | some NEON implementations have a 128-bit wide ALU. Cortex A8 and A9 do not. Their 128-bit timings are worse than their 64-bit timings. |
| 23:48.01 | mnemoc | pidpawel: by default you lose the memory reserved to mali, fb, ve and g2d |
| 23:48.21 | pidpawel | i said that i set in .config to about 900MB of memory but i only see about 500 |
| 23:48.22 | ssvb | Gumboot: for integer workload they are fully 128-bit wide |
| 23:48.35 | pidpawel | i know that. but its about a 150MB |
| 23:48.43 | mnemoc | pidpawel: you probably have the wrong u-boot then |
| 23:48.59 | Gumboot | ssvb: Are you sure about that? |
| 23:49.09 | ssvb | Gumboot: yes, of course |
| 23:49.19 | mnemoc | pidpawel: u-boot spl initializes the dram, and the kernel takes it from ATAG_MEM |
| 23:49.39 | pidpawel | hmm. so i should try to update u-boot's spl? |
| 23:49.52 | mnemoc | pidpawel: nand or mmc? |
| 23:50.11 | pidpawel | hmm. when i look into files it seems that i made a mele a1000 uboot :D |
| 23:50.12 | ssvb | Gumboot: the timings for 128-bit floating point instructions are worse than 64-bit timings, that's true |
| 23:50.14 | pidpawel | mmc ;P |
| 23:50.37 | mnemoc | pidpawel: that's why you got 512 :) build a u-boot for cubieboard |
| 23:50.55 | pidpawel | ok. thanks for finding out a problem ;) |
| 23:51.01 | mnemoc | yw |
| 23:53.45 | Gumboot | ssvb: You seem to be right. I guess I could try timing a floating-point loop, but I kind of don't care about floating-point. |
| 23:53.56 | ssvb | Gumboot: here are the timings for integer NEON instructions in A8 - http://infocenter.arm.com/help/topic/com.arm.doc.ddi0344k/ch16s06s02.html |
| 23:55.32 | Gumboot | I wonder if it's the floating-point pipe that's been expanded to 128-bit on A7, then. |
| 23:55.35 | Gumboot | OR maybe nothing at all. |
| 23:55.53 | ssvb | Gumboot: Q registers are 128-bit and D registers are 64-bit, there are indeed a couple of instructions that are slower when working with 128-bit registers (VCLS/VCLZ/VCNT/VBIT/VBIF/VBSL/VABA) |
| 23:55.58 | Gumboot | There was this one time they made me do floating-point code. That must be where I got these crazy-ass numbers from. |
| 23:56.51 | ssvb | but the vast majority of the most common integer instructions can process 128-bit data in 1 cycle |

| 23:58.06 | ssvb | too bad that A7 documentation does not provide cycle timings information, so we can't check it |
| 23:58.24 | pidpawel | 814MB right now. seems to be good |
