| 20:10.25 | *** join/#arm-netbook discopig (~discopig@unaffiliated/discopig) |
| 20:47.53 | steev | chrs_: i do |
| 20:51.11 | hno | popolon, normally 912MHz. |
| 20:51.32 | hno | for all A20 chips. |
| 20:54.43 | popolon | hno, thanks |
| 20:54.48 | popolon | as I seen 1Ghz somewhere |
| 20:55.16 | popolon | and a20 Olinuxino also didn't write frequency on it's site |
| 20:57.25 | popolon | someone today said me than a7 is crappy |
| 20:57.32 | hno | popolon, Allwinner markets that as 1GHz. just as they market the 1.008MHz of A10 as 1.2GHz... |
| 20:57.59 | popolon | but after the spec, that's a little slower than a8 for int/cpu operation |
| 20:58.08 | popolon | and far faster for float/simd |
| 20:58.21 | hno | popolon, a single core A7 is generally less than a single core A8. |
| 20:58.29 | popolon | yes |
| 20:58.41 | popolon | but not other problems isn't it ? |
| 20:58.50 | popolon | it also use less energy |
| 20:58.58 | popolon | I would like to run it 24/24 |
| 20:59.14 | hno | <PROTECTED> |
| 20:59.53 | popolon | and on fp will be really faster, if applications are multithreaded so |
| 21:00.20 | popolon | well I will try it :) |
| 21:00.32 | hno | there is reports of A20 at full utilization being significantly hotter than A10 at full utilization, but it also chews a bit more processing/s than the A10. |
| 21:00.52 | hno | getting more done. |
| 21:01.20 | popolon | is there some bench ? |
| 21:01.31 | popolon | I don't want to use it at full power every time |
| 21:01.40 | popolon | in fact, only some times, rarely |
| 21:02.16 | popolon | enough power to some crypted network operation and some really light personal web service is enough for me |
| 21:02.30 | popolon | and some other nework applications |
| 21:02.41 | popolon | +t |
| 21:03.07 | hno | popolon, I haven't run any benchmarks myself. Only seen reports from others. |
| 21:03.30 | popolon | didn't find benchmarks with A10 vs A20 |
| 21:03.43 | hno | no links, but most likely in the linux-sunxi mailintlist archives. |
| 21:03.48 | hno | somewhere.. |
| 21:03.59 | popolon | oh, thanks I will search for that |
| 21:04.14 | hno | popolon, first stop is linux-sunxi.org |
| 21:04.26 | popolon | does a20 shutdown the second core in low usage mode ? |
| 21:05.25 | popolon | ok thanks ;) |
| 21:05.35 | popolon | I will press the buy button :⁾ |
| 21:05.41 | hno | I don''t know how well developer power control is, but the hardware can dynamically enable/disable each core. |
| 21:07.08 | hno | others in #linux-sunxi channel might be able to answer that question if asked during daytime european time. |
| 21:08.44 | popolon | ok, I will add this channel to my list of channels then |
| 21:08.47 | popolon | thanks a lot |
| 21:30.26 | chrs_ | steev: hey |
| 21:30.39 | chrs_ | steev: got a sec? |
| 21:30.40 | steev | chrs_: hi |
| 21:30.41 | steev | sure |
| 21:30.54 | chrs_ | some questions coming :) |
| 21:31.08 | chrs_ | what distro are you running on your chromebook? |
| 21:35.38 | steev | chrs_: gentoo |
| 21:35.47 | steev | also Kali |
| 21:38.00 | chrs_ | do you have opengl es support? |
| 21:43.22 | steev | chrs_: yes |
| 21:43.37 | steev | well, yes on gentoo, no on kali |
| 21:45.06 | chrs_ | is it hardware support or software support via mesa? |
| 21:47.34 | steev | it's a mixture - you need either xorg 1.12 or 1.13 |
| 21:47.43 | steev | and then you need their opengles libraries |
| 21:48.01 | steev | and then you need to use their xf86-video-armsoc git repository (NOT linaro's) |
| 21:49.04 | steev | http://git.chromium.org/gitweb/?p=chromiumos/overlays/board-overlays.git;a=blob;f=overlay-daisy/media-libs/mali-drivers-bin/mali-drivers-bin-1.20-r123.ebuild;h=6b0a675b0324daaa0d67c7c0b36838358c7a6ad3;hb=HEAD just replace ${PVR} with 1.20-r123 to get the .bin file to extract the opengles libraries |
| 21:49.45 | steev | http://git.chromium.org/gitweb/?p=chromiumos/third_party/xf86-video-armsoc.git;a=summary is their git tree for the video driver |
| 21:49.56 | chrs_ | hmm |
| 21:50.24 | chrs_ | i should i have that stuff installed |
| 21:50.24 | chrs_ | i think |
| 21:50.31 | steev | chrs_: or if you're on gentoo, you can use my github.com/steev/arm overlay just switch to the dev branch to pull in the proper mali-drivers-bin, xorg-server and xf86-video-armsoc |
| 21:50.49 | chrs_ | interesting |
| 21:51.05 | chrs_ | i may end up doing that because i can't get my opengl es stack properly working |
| 21:51.06 | steev | chrs_: if you do, you also need to have an xorg.conf snippet to use the armsoc driver (xorg defaults to fbdev on arm) |
| 21:51.24 | chrs_ | can you post your xorg.conf? |
| 21:51.59 | chrs_ | i'm not using gentoo but i'll switch to it |
| 21:52.04 | steev | steev@rose ~ $ wgetpaste /etc/X11/xorg.conf.d/20-armsoc.conf |
| 21:52.05 | steev | Your paste can be seen here: http://bpaste.net/show/124348/ |
| 21:52.05 | steev | steev@rose ~ $ wgetpaste /etc/X11/xorg.conf.d/10-synaptics-chromebook.conf |
| 21:52.05 | steev | Your paste can be seen here: http://bpaste.net/show/124349/ |
| 21:52.41 | chrs_ | that's it? just one section? |
| 21:52.48 | steev | chrs_: yes, notice the path |
| 21:53.26 | steev | everything else is defaults from the xorg auto configuration itself (i.e. i have no /etc/X11/xorg.conf) |
| 21:53.36 | chrs_ | i didn't either |
| 21:53.42 | chrs_ | i created one to stop glx from loading |
| 21:53.46 | chrs_ | or try to anyway |
| 21:54.35 | steev | chrs_: if you have a 32gb sdcard |
| 21:54.59 | steev | i have an image up at http://steev.net/distfiles/chromeos iirc |
| 21:55.27 | steev | yep, that's the url - the .img.xz - extract that, write it to a 32gb card, and bob's your uncle |
| 21:55.42 | chrs_ | i do have a 32gb sd card |
| 21:55.45 | steev | i should do a newer one but i'm being lazy currently (also read working on other things) |
| 21:55.53 | chrs_ | i was hoping to install onto the internal storage though |
| 21:56.13 | steev | the newer install i have is done on the internal storage |
| 21:56.32 | steev | p1 has the nv-uboot, p2 has vmlinux.uimg, p3 is root and p12 has the boot.scr.uimg |
| 21:56.45 | chrs_ | do you still have the chromeos files? |
| 21:56.52 | steev | hm? |
| 21:56.59 | steev | no, i completely replaced what is on eMMC |
| 21:57.03 | chrs_ | oh ok |
| 21:57.11 | chrs_ | how would you get chromeos back if you wanted to? |
| 21:57.22 | steev | the SPI nor is still the chrome one |
| 21:57.26 | steev | so their uboot boots |
| 21:57.32 | steev | and then loads the nvuboot |
| 21:57.37 | chrs_ | ok |
| 21:57.41 | steev | and that uboot then loads my kernel |
| 21:58.26 | chrs_ | what is the output when you run 'es2_info'? |
| 21:59.23 | chrs_ | http://bpaste.net/show/PlNBKK8VgzqW09SKE5ER/ |
| 21:59.45 | chrs_ | thats some info from my system |
| 22:01.03 | steev | chrs_: that's really old |
| 22:01.07 | steev | the .45 drivers |
| 22:01.18 | chrs_ | ooh.. |
| 22:01.29 | steev | so if you've got a newer kernel |
| 22:01.41 | steev | it isn't gonna work as they modified something kernel side that requires newer drivers |
| 22:01.54 | steev | and i forgot to install mesa-progs on this install, let me do that |
| 22:03.14 | steev | and it looks like i forgot to switch to mali so once mesa-progs installs i'll restart x |
| 22:03.29 | chrs_ | ok cool |
| 22:05.07 | steev | or not. hrm |
| 22:05.17 | steev | i've been working on building a system completely devoid of opengl |
| 22:05.27 | steev | to fix things that look for opengl when we only use opengles |
| 22:05.34 | chrs_ | the mali gpu doesn't support opengl |
| 22:05.38 | chrs_ | only opengl es |
| 22:05.46 | chrs_ | but it does have hardware accel for opengl es |
| 22:05.51 | WarheadsSE | needs to eventually retry on Arch |
| 22:07.00 | steev | chrs_: yes, that's why i'm fixing it to not install anything opengl |
| 22:07.07 | steev | where it = mesa, xorg, mesa-progs |
| 22:07.14 | steev | and pretty much anything else that needs opengl |
| 22:07.37 | steev | i just saw the other day there was a 2012 GSOC project for Blender to run on OpenGL ES |
| 22:18.24 | chrs_ | so you're using mesa for opengl es now? |
| 22:18.40 | chrs_ | i don't think the opengl es apps will run over mesa |
| 22:23.09 | steev | chrs_: correct, that's why gentoo has eselect |
| 22:23.17 | steev | eselect opengl set mali, startx |
| 22:23.20 | steev | done. |
| 22:23.23 | chrs_ | wow |
| 22:23.30 | chrs_ | i've never used gentoo |
| 22:23.42 | steev | it's not for everyone |
| 22:24.00 | steev | and i cheat because i have a bunch of arm boxen, so i build binpkgs of everything |
| 22:24.41 | chrs_ | i only have one :( |
| 22:24.57 | chrs_ | i'm not including my iphone or ipod |
| 22:25.22 | chrs_ | were you able to run es2_info yet? |
| 22:37.11 | steev | no, i have to fix mesa-progs to not require opengl first |
| 22:37.17 | steev | which is gonna take me a bit of time |
| 22:37.22 | chrs_ | how are you going to do that? |
| 22:37.36 | steev | patch out the opengl bits if opengl isn't required? |
| 22:37.44 | chrs_ | sounds tricky |
| 22:38.52 | steev | not really |
| 22:39.03 | steev | but it's not a top priority |
| 22:40.06 | steev | i'm far more interested in fixing chromium 30 to build with vfpv3-d16 |
| 22:41.48 | chrs_ | whats vfpv3-d16? |
| 22:43.19 | chrs_ | when i run es2_info i get |
| 22:43.27 | chrs_ | Error: eglInitialize() failed |
| 22:43.43 | chrs_ | i guess my opengl es driver isn't isntall properly... |
| 22:43.54 | chrs_ | ldd `which es2_info` isn't showing missing libs |
| 22:47.18 | steev | mfpu |
| 22:47.33 | steev | it's mostly for machines that don't have a neon unit |
| 22:47.38 | steev | so marvell and tegra2 |
| 22:47.58 | steev | but there are some boards out there with a broken neon unit as well (efika to2 boards) |

| 23:32.21 | steev | chrs_: http://bpaste.net/show/124380/ its' rather terse as it expects people to be somewhat familiar with gentoo |
| 23:34.12 | chrs_ | ok |
| 23:34.18 | chrs_ | i should probably read up on gentoo first |
| 23:34.26 | chrs_ | since i wasn't even familiar with some of the terms you were using earlier |
| 23:34.27 | chrs_ | thanks |
| 23:35.15 | steev | chrs_: well it's all built from source |
| 23:35.41 | *** part/#arm-netbook DonkeyHotei (~danielg4@70-36-141-91.dsl.dynamic.sonic.net) |
| 23:35.55 | chrs_ | well, except for the binary mali opengl es drivers |
| 23:36.16 | chrs_ | or any other binary drivers i'm not aware of |
| 23:36.19 | chrs_ | but i get your point |
| 23:36.33 | chrs_ | it's different system from where i'm coming from |
| 23:37.05 | steev | chrs_: well, the only difference there is that it copies the files into place, and makes it switchable in the gentoo way of doing things |
| 23:38.10 | chrs_ | ok |
| 23:38.17 | chrs_ | i'm a little scared that i have to partition things myself |
| 23:38.25 | chrs_ | i'm not sure i want to blow away chromeos at this point |
| 23:38.55 | steev | haha |
| 23:39.00 | chrs_ | the ubuntu script i'm using to install chromeos (i've busted the system a nubmer of times and reinstalled) lets me keep chromeos on a small 1gb partition |
| 23:39.01 | steev | well |
| 23:39.19 | steev | the way i do it, worst case you can always plug in the restore chromeos usb and replace everything |
| 23:39.25 | chrs_ | i thnk it's 1gb, might be 2 |
| 23:39.35 | steev | also can just use an sdcard |
| 23:39.38 | chrs_ | the restore chromeos usb? |
| 23:39.48 | chrs_ | i got this machine off craigslist |
| 23:39.55 | chrs_ | i don't think it came with a "restore usb" |
| 23:40.19 | steev | which is what i did until i was ready |
| 23:40.19 | steev | at some point i'll remove the screw to make the NOR read-write and write the u-boot to it |
| 23:41.13 | chrs_ | you have a restore chromeos usb stick that came with the machine? |
| 23:42.00 | chrs_ | i guess installing to this 32gb sd would be better than nothing |
| 23:44.07 | steev | chrs_: you can download a restore image |
