| 23:59 | michaelcubox | what is DT? |
| 23:59 | shesselba | make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- -j2 uImage |
| 23:59 | shesselba | cp arch/arm/boot/zImage arch/arm/boot/zImage.orig |
| 23:59 | shesselba | make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- dtbs |
| 23:59 | shesselba | cat arch/arm/boot/zImage.orig arch/arm/boot/dts/dove-cubox.dtb > arch/arm/boot/zImage |
| 23:59 | shesselba | make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- -j2 uImage |
| 00:00 | shesselba | gives you a bootable uImage with cubox device tree blob (dtb) attached |
| 00:00 | shesselba | allows you to boot a DT kernel without DT support in u-boot |
| 00:01 | michaelcubox | but i can also use the hf compiler,right? |
| 00:02 | shesselba | yes |
| 00:03 | michaelcubox | ok, you mean this git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc.git, right? |
| 00:03 | shesselba | nopr |
| 00:03 | shesselba | mainline linux kernel |
| 00:04 | shesselba | torvalds/linux.git |
| 00:04 | shesselba | or just download 3.7.0 tar bz2 from kernel.org |
| 00:05 | michaelcubox | so git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git |
| 00:05 | shesselba | yes |
| 00:05 | michaelcubox | cuase in cubox forum somebody told me to clone the arm-soc.git |
| 00:06 | shesselba | arm-soc.git is not a stable repository |
| 00:06 | michaelcubox | ok. you have 3.7 running on your cubox? |
| 00:06 | shesselba | 3.8-rc1 |
| 00:07 | shesselba | so yes, I had 3.7 running on my cubox too |
| 00:08 | shesselba | 3.8-rc1 is what you will get if you clone torvalds/linux.git |
| 00:08 | michaelcubox | i run make dove_defconfig and after that your set of commands to get the uImage and modules with make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- -j2 modules? |
| 00:08 | shesselba | I never built any modules |
| 00:08 | michaelcubox | oh ok. and how does it run on the cubox? |
| 00:09 | michaelcubox | ok. i just need a kernel with sata and ext4 + lan. kiss |
| 00:09 | shesselba | sata and lan are enabled by default .. just select ext4 in menuconfig |
| 00:10 | michaelcubox | ok. I guess that i dont have to set any setting to get the full 1gb ram,right? |
| 00:10 | shesselba | just don't set mem= cmdline parameter |
| 00:12 | michaelcubox | i dont know this parameter. i did disable framebuffer devices and dove gpu in 3.57 and 3.6.9, that was all |
| 00:12 | shesselba | there is no framebuffer nor gpu in mainline linux |
| 00:14 | shesselba | mem is set to 1G in dtb, if you override it with a lower value on boot, there will be less mem available.. that's why I said just don't set mem= in uboot cmdline |
| 00:14 | michaelcubox | so DT tells the system normally while compiling,which drivers are needed,right? |
| 00:14 | shesselba | no |
| 00:14 | michaelcubox | ok. thx for the advice |
| 00:14 | michaelcubox | thats what i found with google ;-) |
| 00:15 | shesselba | DT tells the kernel what devices are available during _runtime_ |
| 00:15 | shesselba | if there is a driver in your kernel for a specific device it will match with the DT information |
| 00:15 | shesselba | basically all that's available on your cubox is also selected by dove_defconfig (except ext4) |
| 00:16 | michaelcubox | so i can tell that i have a specific wlan stick, and if this stick is plugged in, the kernel loads the module. |
| 00:17 | shesselba | usb wlan is not part of DT but usb bus probing |
| 00:17 | shesselba | just compile the driver into ther kernel (y) or as module (m) and it will work |
| 00:17 | michaelcubox | ok, just for example ;-) |
| 00:17 | michaelcubox | so where are you from? im from germany |
| 00:17 | shesselba | me too |
| 00:18 | michaelcubox | .... |
| 00:18 | michaelcubox | welche stadt? |
| 00:18 | shesselba | hannover |
| 00:18 | michaelcubox | ich wohne in bonn und studiere informatik |
| 00:18 | michaelcubox | habe vorher fisi ausbildung gemacht |
| 00:19 | shesselba | we should stick with english as there will be others wondering what you say ;) |
| 00:19 | michaelcubox | ok,no problem |
| 00:19 | michaelcubox | so what are your services running on the cubox? |
| 00:19 | shesselba | none, I am porting it to mainline linux only |
| 00:20 | shesselba | but in some distant future it will be xmbc for sure |
| 00:20 | michaelcubox | lets hope the gpu will be ready for this some day. the yet results are not that.... |
| 00:21 | shesselba | _rmk_ is working hard on convincing linux people to get it into mainline |
| 00:22 | michaelcubox | i like cubox,because its small, has 1gb ram and especially e-sata |
| 00:23 | michaelcubox | i have done some work to get debian in the cubox installer and you can select it from there and it is on your device in about 10min |
| 00:25 | shesselba | great, I installed it from some generic installer and also ubuntu 12.10 armhf .. but as I said, currently I only use it for kernel integration |
| 00:28 | michaelcubox | do you also have other embedded devices? here i got a pogoplug and a rasperry |
| 00:28 | michaelcubox | alix did die last month... |
| 00:28 | shesselba | yeah, I got some others from marvell to port them to mainline |
| 00:28 | shesselba | and I still have a dockstar |
| 00:29 | michaelcubox | nearly same device as the pogoplug |
| 00:29 | michaelcubox | is porting your main job aor do you also have antoher one? |
| 00:30 | shesselba | I am a research engineer at Leibniz Universitaet Hannover |
| 00:30 | lubiana | shesselba: wow, i thought im the only one in hannover owning a cubox |
| 00:30 | shesselba | nope |
| 00:32 | michaelcubox | lol |
| 00:32 | neofob | shesselba: is the tdma patch by Phil Sutter for mv-cesa in 3.7 mainline now? |
| 00:33 | shesselba | hmm, don't know - you have a link to the patch discussion? |
| 00:33 | neofob | shesselba: http://thread.gmane.org/gmane.linux.kernel.cryptoapi/7162 |
| 00:34 | michaelcubox | good night guys, see you soon |
| 00:36 | shesselba | is there a more recent discussion about a real patch? last msg is from Jul 2012.. |
| 00:37 | shesselba | you should encurage phil sutter to resend his patches |
| 00:37 | neofob | not that i know of, i'm looking for hardware support for the crypto engine and openssl via cryptodev so i found that on internet |
| 00:37 | shesselba | there is mv_cesa support in mainline linux |
| 00:38 | shesselba | but I don't know if it is using dma capabilities yet |
| 00:39 | neofob | i'll try with current 3.7 first; currently cryptodev & openssl dont fully work in 3.5 |
| 00:39 | neofob | discussion on solid-run forum: http://www.solid-run.com/phpbb/viewtopic.php?f=9&t=634 |
| 00:39 | shesselba | what is the current approach with cryptodev vs the other one? |
| 00:40 | shesselba | IIRC there are two different crypto apis? |
| 00:40 | neofob | the other one is OCF (i think) and it was stopped developed like 2 years ago |
| 00:41 | neofob | at least cryptodev last release 1.5 is august 2012 |
| 00:41 | shesselba | ok, I quickly checked crypto support some month ago while enabling it on dove (cubox soc) |
| 00:41 | shesselba | and I remember hardware crypto support for aes and some other |
| 00:42 | shesselba | so basically it is accelerated on your cubox with recent kernel |
| 00:42 | shesselba | (with "older" kernel from rabeeh too) |
| 00:43 | neofob | ok, hopefully it works out of the box this time; the "old" one has some patches from vDorst that use init call instead of DTS thing that i saw you committed |
| 00:44 | shesselba | well, if you don't use DT then you need to patch mv cesa support the old way .. I haven't checked what the vDorst patch does but I guess it is still non-DT kernel |
| 00:44 | shesselba | and yes - mv_cesa init on dove was missing |
| 00:46 | neofob | ok, thanks for the info shesselba; i'm heading to my friend's place for free food now :D (it's almost 7pm in east coast america now) |
| 00:47 | shesselba | ok |
| 02:26 | rmull | Yikes, tried to play a video with mplayer... that didn't go well. |
| 02:27 | Punkley_Chillin | yer don't do that |
| 02:27 | Punkley_Chillin | not untill we get a avconv and hardware encoding working :) |
| 02:28 | rmull | How close are you guys? That'd be a dramatic accomplishment |
| 02:36 | rmull | rabeeh: Any chance the 2GB RAM of the new cubox is pin-compatible with the 1GB of the old one? |
| 02:37 | rmull | for the purposes of swapping ram ICs |
| 13:25 | Sage | rabeeh: pong |
| 19:43 | N30N | Hi guys, hope you had a happy holiday and new year. :) |
| 19:44 | N30N | Hmmm no dotarray about. |
