| 00:51.49 | br- | penguin42: is the point.. latency is the major factor at play |
| 00:55.18 | penguin42 | br-: Yeh, although I have seen truly grim USB interfaces that are painful |
| 01:06.33 | br- | turns out i've been calling this new caddy a pos all night because it wouldn't do more than 15mb/sec sequential |
| 01:06.50 | br- | except the tar | tee /tmp/error-log | tar combo i was using was actually teeing an entire copy of the disk back on itself, ha |
| 01:07.11 | penguin42 | hehe |
| 01:07.43 | br- | tried truncating it, then gdb dup2'ing a /dev/null fd over it, which caused osx to desparsify the newly truncated error log, which kicked off an uninterruptible writing of 200gb worth of nulls |
| 01:07.51 | br- | has just rebooted the machine |
| 01:08.50 | bsdfox_ | libv, the problem I kept running into was libs in /usr/lib/arm-linux-gnueabihf/mesa-egl taking priority over the mali libs |
| 01:09.10 | bsdfox_ | just mv mesa-egl mesa-egl.bak works |
| 01:09.31 | bsdfox_ | apt-get remove on all the packages providing want to get rid of lots of other stuff (ubuntu-desktop, unity etc) |
| 01:10.21 | bsdfox_ | I do get somewhat poor performance it seems. 24fps in glmark2-es2 |
| 01:14.16 | penguin42 | that sounds exactly like it's vsync locked |

| 01:21.35 | ssvb | about moving /usr/lib/arm-linux-gnueabihf/mesa-egl out of the way, this did not seem to help GeorgeIoak earlier, but it's good to know that it generally works :) |
| 01:21.57 | bsdfox_ | you still need to have mali setup right :) |
| 01:22.15 | ssvb | yes, sure |
| 01:24.13 | ssvb | bsdfox_: about 24fps, was it a fullscreen benchmark with 1920x1080 screen resolution? |
| 01:24.30 | bsdfox_ | windowed default size with 1920x1080 |
| 01:25.15 | ssvb | unity desktop? |
| 01:26.02 | bsdfox_ | fluxbox |
| 01:27.03 | ssvb | that's strange, the performance is a bit too low |
| 01:27.56 | ssvb | bsdfox_: you can also try this instead of xf86-video-mali - https://github.com/ssvb/xf86-video-sunxifb |
| 01:28.50 | ssvb | bsdfox_: if you don't use a compositing window manager, then the performance should be good |
| 01:32.57 | ssvb | bsdfox_: I hope to also get reasonable performance with the heavyweight kwin/gnome-shell/unity things in a day or two |
| 01:33.41 | bsdfox_ | hmm I guess SUBSYSTEM=="misc" was my problem with udev.. removed that and I think it's working |
| 01:34.15 | bsdfox_ | I am rerunning glmark2-es2 right now |
| 01:35.37 | bsdfox_ | ssvb, what changes do I need to make to use your xf86-video-sunxifb? just change the drive in xorg.conf? |

| 16:53.25 | hramrach | not so far AFAIK |
| 16:53.47 | mnemoc | there is a CF-ish variant of eoma |
| 16:54.12 | hramrach | that's pretty much the same thing, just smaller |
| 16:54.26 | aexl | Lachezar: http://elinux.org/Embedded_Open_Modular_Architecture |
| 16:54.50 | Lachezar | Both these (PCMCIA/CF) require manufactured ports. Probably better for commercial use, but I find it a tad bit hard to use. |
| 16:55.33 | Lachezar | asks for some leniency since he's a total noob in the area. |
| 16:55.33 | mnemoc | the point of eoma is to be granny-exchangeable |
| 16:56.07 | hramrach | there are more recent connector designs than pin-socket like PCMCIA |
| 16:56.31 | Lachezar | mnemoc: You mean that I can swap two SOC borads easily: That's commendable, but I still have to make the other side of the hardware, that's what bothers me. |
| 16:56.33 | hramrach | and grannies tend to bend the pins on this particular one occasionally so not that great |
| 16:56.54 | mnemoc | hramrach: good point :) |

| 16:58.44 | Lachezar | Well... Thats VERY commendable, but couldn't an ISA-style port be the same? Maybe I'm putting my noob nose in an area reserved for high-end corporate developers? |
| 16:59.33 | hramrach | ISA would do I guess. You caould have a case for the card with edge connector like those console cards do |
| 16:59.41 | mnemoc | Lachezar: but how many connections an ISA-style connector supports? |
| 16:59.46 | hramrach | but ISA is HUUUUGE |
| 16:59.59 | mnemoc | I mean, connect/disconnect the card |
| 17:00.34 | Lachezar | I was thinking of building a RACK-mountable MULTI-EOMA chasis with KVM integrated, and I still believe a bit more noob/amateur-friendly port could help. |
| 17:00.46 | hramrach | not sure about ISA but those console cartridge connectors are supposed to be replaceable |
| 17:01.13 | Lachezar | I do not mean ISA as in THE-ISA, just the same style: one end on the board is the connectors... |

| 17:04.55 | hramrach | yes, it's male connector on the board. when you have full depth kit with rails all the way and no way to put in the card other than the right way and the card going fully in it's pretty much granny-proof |
| 17:05.16 | mnemoc | lkcl: any suggested source for buying the male pcmcia connector? Lachezar asking |

| 17:14.23 | hramrach | oh, well |
| 17:14.53 | hramrach | the eoma goes for minimalistic interface so all parts are mandatory and pretty much any SoC can do that |
| 17:15.03 | hramrach | so all cards should be interchangeable |
| 17:16.30 | hramrach | but requires adaptation of the minimalistic interface in the eoma device making it needlessly more costly if a signal is converted from the minimalistic interface to something the SoC would support anyway but there is no room for it on the eoma interface |
| 17:17.30 | hramrach | on the other hand, if anything is allowed and everything is optional mixing and matching cards and devices becomes difficult |
| 17:17.32 | Lachezar | mramrach: Like a video signal that's HDMI-like, and not RGB-TTL (or whatever it's called)? |
| 17:17.41 | L84Supper | eoma is an incomplete standard with no shipping products, just about anyone with experience designing hardware has better suggestions for a standard |
| 17:18.52 | hramrach | the problem is if you design an interface with HDMI, e-DP, DP and LVDS as EDM has noc hip will do all |
| 17:19.02 | hramrach | so it must be optional to provide those |
| 17:19.39 | L84Supper | or have enough pins to support them on the standard connector |
| 17:19.41 | hramrach | and then you have to check that your EDM module and EDM screen have some intersection in the subsets on EDM they support |
| 17:19.58 | L84Supper | the RGB-TTL pins are a big waste of pins |
| 17:20.03 | hramrach | eno longer plug anything anywhere |
| 17:20.21 | hramrach | no, they aren't. they are the least common denominator |
| 17:21.37 | hramrach | maybe you whould choose a different one if you designed from scratch today but it's the single display interface EOMA has |
| 17:21.54 | hramrach | so that every card has to provide and every screen has to consume |

| 17:28.17 | hramrach | the olinuxino and cubieboard seem cool. If they are lacking then you do have some requirements ;-) |
| 17:28.44 | Lachezar | hramrach: Well... Something like a kiosk-stand, but with a USB bar-code scanner, optional keyboard, no mouse, touch screen, etc. |
| 17:28.46 | hramrach | also odroid for more powerful computer-like device |
| 17:29.06 | Lachezar | hramrach: No, they tend to be very close to what I need... |
| 17:29.09 | hramrach | any of those mentioned so far can do a kiosk-stand |

| 17:29.54 | L84Supper | https://www.olimex.com/Products/OLinuXino/A13/ |
| 17:30.26 | hramrach | another alternative is to get a tablet (=working touchscreen out of the box) and hide it in the stand |
| 17:30.47 | mnemoc | has seem too many ipads deployed that way :| |
| 17:30.54 | mnemoc | seen* |

| 17:31.41 | mnemoc | sure, but buying an ipad for that??? |
| 17:31.47 | hramrach | but need to fiddle with Android/iOS so in the end not good tradeoff |

| 20:17.20 | wingrime | I think flash have to be same blank size |
| 20:19.52 | aexl | can't you find the same chip? |
| 20:20.05 | wingrime | right |
| 20:20.46 | wingrime | I even can replace A10 to A10s as they pin-to-pin compatble |
| 20:21.23 | aexl | wouldn't do it^^ |
| 20:23.50 | wingrime | for that I must have IR-solder |
| 20:27.15 | aexl | if i could do that i would solder a board with imx6 quad and sata |

| 20:29.56 | wingrime | a31 faster than a10 ? and why they not used 4x cortex a9? |
| 20:31.07 | RaYmAn | a7 is probably faster than a9 |
| 20:31.54 | RaYmAn | but not exactly a lot of benchmarks yet |
| 20:33.14 | mnemoc | wingrime: the A10 and A10s are NOT compatible at all |
| 20:35.38 | aexl | a13 then. |
| 20:38.28 | mnemoc | eh? |
| 20:38.37 | mnemoc | even more different |
| 20:38.51 | aexl | oh |
| 20:40.08 | aexl | but i'm with wingrime that there was something pin compatible ... |
| 20:43.41 | mnemoc | A10 and A20 |
| 20:44.29 | aexl | right^^ |
| 20:50.43 | aexl | wingrime: hm only ft232h mentions jtag www.ftdichip.com/Products/ICs/FT232H.htm |
| 20:50.58 | aexl | wingrime: but ft232r mentions at least bit-banging www.ftdichip.com/Products/ICs/FT232R.htm |
